Title: Positive Grid BIAS Amp Designer (IOS)
Post by: BackDAWman on November 14, 2013, 08:10:30 PM
I did a search on the forum but came up with ziltch therefore:

Has anyone tried Positive Grid's Bias? These are the guys who came up with Jamup Pro XT. In my opinion the best amp/fx simulator on iOS.

I have bought it but haven't tried it yet. It looks great in the promos.

I look forward to the valued opinions of the members here .

I took delivery of an Ipad Air 128GB 3G today - it flies thru tasks  that stall and halt my old ipad2 cold.

Been playing my bigsby JTV-59 into Sonuus I2M + Apple Lighting USB  Camera adapter as audio interface and Skullcandy Titan II travel buds for headphones with the iPad Air

Positive Grid Bias is really amazing -  I dare to say its a spectacular time to be a guitarist. Bias has very good Clarity, The Amps sound and react very close to the real thing, best Tube Amp tone toolbox on IOS today (Nov 2013) with many controls to satisfy those who crave getting inside, its all emulations of circuits and a  Great amp in the room simulator. I was obtaining great tone in seconds  reminiscent of Ritchie Blackmore playing opening to 'Lazy' off the  Deep Purple Machine Head record. sounds great to my ears  Worth the $19.99, and marries into JamUp Pro XT very well. Very Happy.

Good to hear you confirm that this app is a winner, Elantric.

I am super excited about this one.  From all the demos I've watched it sounds just amazing, and the level of tone control looks unprecedented. So I guess this app might be the one to push me off the cliff and either upgrade my ipad 3 to iOS 7 or really bite the bullet and get the ipad air.

Some cool demos.

It does look extremely cool.  Of course the very small part of my brain that tries to keep the much larger G.A.S.-infected portion of my brain in check wonders whether or not it can achieve any tones that I can't get with my current gear.  E.g. The GR-55 may not let you switch out the tubes or adjust the bias on its amp models but it does have a lot of parameters, distortion pedal effects too many to count, etc. and I have to wonder if one couldn't dial in nearly enough any tone that you could dial in with BIAS just using a different paradigm using Roland, Line 6, fill in the blank with your favorite sufficiently complex modeling software.

In the end I'm sure my curiosity will win out and I'll get this - if you already have an ipad its quite inexpensive as far as amp modeling software goes.

I have been so impressed with Jamup Pro XT that I bought this as soon as I received the promo in my email.

The GR55 has some great usable sounds but I still pine for the REAL sound of a tube amp. I much prefer the models on Jamup and even the models on my old Behringer Vampire feel better than those on the GR55, especially the dirty tones. I stick with the GR55 purely for the flexibility, alt. tuning and the access to synths.

I get all the tube amp tones and playing response I need using Positive Grid Bias. I've been so impressed with Positive Grid BIAS Amps that i'm questioning the point of owning my Kemper. Positive Grid BIAS is a serious app for all Tube amp Tone Purists. 

https://itunes.apple.com/app/id711314889?mt=8&&referrer=click%3Dbb041408-4cf4-4e4f-a620-711e171201d4 (https://itunes.apple.com/app/id711314889?mt=8&&referrer=click%3Dbb041408-4cf4-4e4f-a620-711e171201d4)

Description
BIAS is an Amp Designer, Modeler and Processor for iPad. It's warm, accurate and more versatile than any other modeler, processor in hardware or software ever created.

BIAS starts with stunning replications of 36 of the most sought-after vintage and modern amps in rock 'n' roll history and then lets you customize them to respond perfectly to your unique touch and feel. Swap out the tubes, preamp, transformer, tone stacks, cab and mic—even change the tube's bias—to create your dream amp and distinctive signature sound. Tap once to open your BIAS amp in JamUp and add awesome multi-effects.

Close your eyes, and you'll swear you're hearing the real thing. With BIAS, you own a complete virtual collection of the most coveted and unique guitar amps of all time—some dating as far back as the 1940s. Every amp model is meticulously engineered to respond to your playing with immediacy, sensitivity and realism that make you not only sound better but also play better. And BIAS sounds great on bass guitar, too.

But BIAS doesn't stop there. Create totally new sounds by designing your custom dream amp. It's as easy as tap and drag. Using BIAS' highly intuitive and lightning-fast interface, it's child's play to instantly swap out colorful tube preamps, lush distortion circuits, classic tone stacks, boutique power stages, custom-built transformers and cabs loaded with specially matched speakers. The result is a depth and range of tones not possible using traditional guitar amps or other modelers. Whether you're a classic rocker, metalhead, jazz player, bluesman or singer-songwriter—and whether you understand how amplifier electronics work or not—you'll be dialing in killer, exclusive tones in a heartbeat.

BIAS integrates seamlessly with Positive Grid's free JamUp XT and optional JamUp Pro XT guitar multi-effects apps for iPad, expanding BIAS into a powerful and completely unified professional guitar system for live use, recording and jamming. Simply tap the JamUp icon on BIAS' upper bar to open your current BIAS amp setup directly in either JamUp XT or JamUp Pro XT. JamUp XT adds 1 amp and 6 effects to your BIAS rigs. JamUp Pro XT adds fully 6 amps and 16 stomp-box and premium rack effects - including distortion, compression, tape delay, tremolo and spring reverb. Both JamUp XT and JamUp Pro XT include Jam player, 8-track recorder and phrase sampler, tuner and metronome, effectively turning BIAS into a recording studio and top-of-the-line practice utility.

BIAS works with GarageBand and other audio apps using iOS 7's Inter-App Audio and Audiobus. Whether recording, songwriting, or honing your chops—at home or on the road—BIAS places unequaled tone at your fingertips.

If it were me, I would get the sounds I like with the grid and profile them with the Kemper. Done
Then you go from there, as the Kemper always gives the profile tons of control and a gain structure that is 90% of the time better than the original.
I wish I could borrow an iPad...

I own a Kemper, and this app still has me jonesing for a new iPad.  I completely geek out over simulations that let the user swap tubes, change bias and sag, etc.  Amazing I never ponied up for an AxeFX, but I was pretty addicted to Guitar Rig for a while.

Very powerful words. I love my Kemper, but will definitly give this a try. I don't wanna jump to sell my KPA, I tried a lot of things over the years and so far, the KPA is the only thing I've found satisfying. But definetly want to give BIAS a try, as I trust your judgement Paul

Ps: I just got a Pod XT live to contoll my Jtv89 and was surprised (even with some tweaking) just how mediocre it sounds and will only be using it to swicth JTV models???

One thing to consider - even if Positive Grid's software algorithms are as good as, or better than, the Kemper's - is how good the Kemper is from an analog perspective, e.g. the quality of the guitar input, the FX loop, and all of the outputs, to make no mention of the MIDI I/O and expression pedal features.  You'll need some very nice accessories to make your iPad rig stack up, whatever app you're running.

But I still want Positive Grid.  :)

Consider an upgrade to the POD HD line - the difference is night and day.  I personally thought that entire era of Line 6 product (Vetta/ xt) was pretty harsh sounding.  (And I still own a Vetta II, so I've spent my share of time trying to like it.)

Actually an Old XTLive makes an excellent MIDI Foot controller for an ipad guitar rig using iRig Pro+Positive Grid BIAS+Jamup Pro XT

Just connect the iRig Pro 5pin MIDI IN cable to XTLive 5 pin MIDi Out.

I got the Pod XTlive as an inexpensive alternative($99 shipped) to only switch models on my JTV89. I'm gonna try and cut it doen to a light weight package just for that purpose. I was still surprised at how it sounded.

Myself, regarding the Kemper -  I still have not connected well with its lack of assignable remote control for the Kemper FX, and the rear FX Loop is more of a kludge / compromise IMHO. So I'm in the camp of those who feel let down that after 2 years - these issue remain with my Kemper:

* Kemper still lacks an official foot controller. The KPA UNO FCB-1010 is not ideal since its not expandable and can not control other gear in a system.
* The patch organization remains a kludge IMHO , and mentioning on the KPA forum that you want an official Win/Mac based KPA patch editor / organizer will make you a target of derision with the  response "Real men do not need an Editor  / Organizer"

* Even with latest firmware, many of my KPA controls remain "non functional"   - while we await yet another firmware update. Perhaps in 2014 there will be 100% working controls, but i fear that will occur the same day they announce the "new Kemper II with more DSP horsepower"

BTW - I now own

2011 Ipad2 64GB

2012 Ipad Mini 32GB

2013 iPad Air 128GB

I have upgraded all to latest IOS 7, and Positive Grid BIAS runs on any of the above iPads. True it works best on the Ipad  Air, but the main thing you need is IOS7. I would avoid using a 1st gen Ipad.

Post by: supernicd on November 20, 2013, 12:25:09 PM
I've been fawning over the KPA and the AxeFX II for quite a while now, but ultimately haven't pulled the trigger.  The decision to get the new iPad is a lot easier for me to justify since it does all sorts of other music related stuff (DAWs, synths, sequencers, FX), and not to mention it does all sorts of other non-music things like email, web surfing, etc.  And its half the cost of either of those, leaving plenty of room  for any needed accessories.

I have to say though, I'm having some trouble getting pleasing tones out of Bias.  Mostly they all sound kind of thin and lacking punch to me.  Based on the ravings its getting and from what I'm seeing and hearing in the videos I figure it must be something in my signal chain.

I've tried guitar-->apogee jam-->lighting-30pin adapter-->CCK-->headphones
and... same as above but iPad headphone out into the aux in on a Fender Mustang IV.

Maybe the Apogee Jam is the issue.  I know these are quality interfaces and I don't remember having any issues with it before.  But I haven't used it for a while.  Perhaps something's gone wrong with it.

Guess I'll try some other configurations tonight.

With my Guitar on "10"  - most ipad audio interfaces sound about the same with Positive Grid BIAS.
Where I do hear differences in ipad Audio Interfaces and 16bit vs 24 bit  is when I back the Guitar volume down in the "2" to "7"range  - this is where I hear that my 24bit iRig Pro has lower noise / no sputtering. (the Apogee Jam should be comparable - but Ive never actually tried one). The Sonuus I2M sounds good too, but a bit more noise (since its only 16bit), and the Behringer IS-202 has even more hiss and noise - indicating the ipad "sees" the IS-202 audio interface as 16 bit only.

I agree, these are huge oversights and valid complaints.  I know that I'm not using my KPA to its full potential simply because I find it a little too tedious to download profiles, sweat the naming issues, get them on a thumb drive, etc. etc. etc.  I wish Kemper had adopted a more sensible set of naming conventions from the get-go (legal departments be damned!) and allowed for the ability to audition profiles over a USB cable or something.  I'm basically coasting along on Maurizio's backup - his work has been a big help - but who knows what I'm missing from the profile exchange.

Mainly I dig the Kemper for reasons I hadn't even considered when I bought it - it's a really solid piece of hardware that acts as an excellent mixer/ central hub in a studio environment.  And yeah, I have a few go-to profiles that sound great.

I have a few other interface options, as well as a few other possible output destinations, though none of the gear you're using.  It's kind of difficult to describe what I'm hearing.  The tones basically sound right, just slightly more anemic than what I would have expected.  Not drastic, but enough that I'd prefer using one of the various other modelers I have in my arsenal.  So I'll try some more experiments (hopefully I get some guitar time later today) and report back, maybe with some better results.

Which all boils down to the importance of using gear that suits YOUR needs, and not relying 100% on third party recommendations.

QuoteI've tried guitar-->apogee jam-->lighting-30pin adapter-->CCK-->headphones
and... same as above but iPad headphone out into the aux in on a Fender Mustang IV.

Headphones are kind of a wildcard when it comes to amp tones, and "anemic" is a pretty likely outcome.  As for the Mustang, have you tried turning off Bias' speaker emulation?  (I assume this is an option.)

Try to listen to Bias through a good powered monitor if you have one.  Otherwise, compare a different modeler or software package through the same headphones and/or the Mustang - do these sound better than Bias to you?

Yes, it looks like bypassing the cabinet is an option so I'll give that a try.  In retrospect, I may have also left the "room" emulation feature turned on, which might not have been the best thing when playing through the cabinet.  I do have some studio monitors and will try those out too.

Thanks for the tips!

I'm really pleased to report that there's no issue with Bias and thin/anemic-ness.  I think the issue when I was using headphones might have been my headphones, and that the issue when originally connecting up to the Mustang amp was most likely the room modeling algorithm was still turned on.  I tried with the same config into the Mustang and just made sure to have the room emulator off.

My new conclusion.  Bias is great.  Really great.  As in - how did these guys do this in a $20 iPad app - too good to be true kind of great.  I haven't owned a lot of these amp models but I've owned a number of tube amps, and the models sound and play like tube amps.  The models sound like I'd expect them to from recordings.  And you can tweak the amp's entire construct.  And that seems very different and more flexible than trying to EQ an amp model or put an overdrive or distortion in front of it to try to coerce the sound you want from it.

I think Bias and I are going to be spending a lot of quality time together, and Positive Grid probably just sold me the rest of their in-app-purchase effects models for Jamup.

Glad to hear it!  I updated our iPad 3 to iOS 7 last night, and I'm looking forward to checking Bias out tonight.  Is it safe to say that this app leaves Amplitube, AmpKit, JamUp, etc. in the dust as far as amp modeling is concerned?  Running all of these options through their paces can be so time-consuming.

I expect my wife and I will be fighting more about who uses the iPad 3 and who uses the iPad 1 now. ;)

I think so.  But in the case of JamUp specifically, it's deep integration with BIAS gives it a whole new life.  Create an amp model of your liking in BIAS then with one click send it to JamUp to add a complete FX chain.  Will be interested to hear your opinion!

Yes  - BIAS with JAMUP Pro XT is my new #1 (I should point out i already owned all the JAMUP Store in app purchases Amp and FX Bundles = got them last spring during a 50% OFF sale)

AmpKit has one or two nice amps too.

Amplitube sounds like a 80's Zoom by comparison to the above.

BIAS with JAMUP Pro XT sounds way better than my Eleven Rack too.

I think it's going to become my #1 too.  Frankly, after I got my setup issues worked out and started playing with it last night, I was kind of blown away to the point where I had to walk away for a while and make sure I wasn't convincing myself it sounded better than it did.  Already thinking about how to integrate this for live use.

Elantric curious, you said it sounds way better then your Eleven Rack (which I also have and have not used since I got my Kemper) but how are you comparing it sound wise to your Kemper. Paul

And yes I find it irritating , after 2 years, that there are still non working buttons, no foot controller, and no editor/librarian for the Kemper

Just using my ears and array of guitars  - and prior decades of knowledge of what tubes amps sound like

Quotehow are you comparing it sound wise to your Kemper. Paul

Go back in this thread and re-read my prior posts
I've been so impressed with Positive Grid BIAS Amps that i'm questioning the point of owning my Kemper. Positive Grid BIAS is a serious app for all Tube amp Tone Purists. 

I'm very tempted to put the Kemper on Ebay - to fund a better tool - a 2nd iPad Air?

I was more jazzed with the Kemper last year - because it held the promise being updated by the same team that created the Access Virus TI,  (I had hoped there would be KPA VSTi Control  / DAW Integration - things modern computer based musicians take for granted )  and frankly the quality of the shared KPA patches was 1000 times better back in 2012, and even today after 18 months of ownership- there remain bugs on the KPA OS
I'm not a metal headbanger - instead I seek Mike Campbell clean to Sonny Landreth / Derek Trucks high gain slide.

90% of the time I use BIAS/Jamup pro  - I land on great tones I can use

Lately with my Kemper - I have to wade through piles of bad "Metal" shared presets. And lets face it - a 45 second Kemper reboot in the middle of the gig is nuts for a live tool, and I have yet to figure out how to control KPA FX and stomp boxes  with a third party foot controller.

I'll have to do my own A/B KPA vs Bias  / Jamup pro  -
shoot-out using only the top 100  great KPA presets I have.

But realize that in the electronics industry we are in a 18-36 month shelf life for most DSP's, pSOC's, Arm CPU's etc.

My gut tells me there will be a "Kemper II" with more power in 3-12 months - (its inevitable), and the value of my 1st gen KPA will drop  big time.


And I can simply mount the iPad to a mic stand  - and use Bias/JamUp Pro "Live Mode" and have instant access to everything I need to control at a gig. Its brilliant, and I can spend time writing songs.

Elantric, you make some very valid points about the Kemper. I use a FCB1010/Uno to control my GR55 and my KPA, with no real issues. I'm not a Headbanger either , but I do play everything from 50's Do-Wop to GNR and Theory of a Deadman. And agree a lot of the Profiles on the echange are of "Heavy Metal" tones, and I too wish there were more clean to edge of breakup profiles, but I find I have more then enough of these to cover everthing I'm required to play.
I'm allways looking for a way to simplify my stage setup and time, so I do find Ipad and Bias intriguing and certainly will give it a try

Quote from: Elantric on November 21, 2013, 08:02:55 AMLately with my Kemper - I have to wade through piles of bad "Metal" shared presets.

I think this is ultimately what's kept me from parting with the cash for a KPA.  You either need to have access to the amps who's sounds you want to recreate, or rely on others'  profiles.  I'm sure there are some great ones, but I know from using other sharing systems like Line 6's, it can get really time consuming to audition lots of patches (or profiles) and separate the wheat from the chaff, particularly when it comes to freebies.  As a result, I don't invest much time in downloading patches for my Line 6, Fender, etc. stuff, and just make my own.  The GR-55 is a bit of an exception with patches on this site.  I do occasionally download and try new patches for it, because it has such a huge range of possible sounds that someone can come up with a sound that I would never have even thought to try to make.

Another thing I like about BIAS is that the editor is built into it, and it is beautiful, intuitive, and well thought out.  There's no external editor to connect it to, and it really feels like you're changing the way the amp is built or set up rather than changing numeric parameter values on an LCD display and trying to translate in your head what that means.  Like you kind of have to in Roland-land.  There is help available in just the right places for someone like me who's never done any custom work on an amp to get an idea of what I'm doing.

Post by: mbenigni on November 21, 2013, 12:03:16 PM
There is definitely a glut of metal amps on the Kemper Profile Exchange, but IMO there's plenty of chaff at all levels of gain, e.g. tons of anemic Vox-alikes, etc. and it takes a long time to sort through them.  What compounds this problem is that any given profile is best at presenting the tone and gain settings that were selected on that amp at the time it was profiled.  The KPA Gain knob and tone stack don't have any real "knowledge" of the amp's architecture the way a proper modeler (AxeFX or any sophisticated software package) would, so you get farther away from the original amp's character as you deviate with these controls.  Thus - you really need to amass a library of profiles not only for your fave amps, but for those amps at different settings.  In one sense there's a simplicity about it:  the profile kind of is what it is, less tweaking; but for the same reason it can be kind of a juggling act: how far can I push this profile before I'm better off jumping to another?

It will be refreshing to work with a piece of software that's simulating a real amp's architecture again.  I love the KPA for its ability to really capture a given amp in the moment, without too much effort or expertise on the user's part, but I also like fiddling with an amps controls and getting a feel for how they really behave.

As for the whole floorboard thing, I gave up on Kemper a long time ago.  Seemed like it would take forever, likely be more than I wanted, and at a higher price than I could afford.  I cobbled together a bunch of homegrown solutions, but Steve is right - none provide effective visual feedback on the floor.

Post by: mbenigni on November 21, 2013, 12:08:28 PM
But I certainly don't mean to diminish the Kemper.  I'll most likely keep mine even if Bias blows me away.  For a long time I was looking to go all-software with more and more powerful computers, but the KPA changed my mind about the importance of good, purpose-built hardware.  There's a lot to be said for preamps, filtering, routing, mechanical UI components (real knobs!) etc. that are designed to complement the software.

Agreed!  The old adage that your tone can only be as good as the worst component in its signal path still holds true.  As for real knobs, etc, I also agree.  Ever tried to pull the mids down during a performance on a GR-55?  it's as simple as click edit, page right, down arrow, press enter, down arrow, down arrow....  :)

I tried doing this a couple of years ago (right before I bought my Kemper, actually) but man is it hard to find buyers for some of the old miscellany I own.  Even for the good stuff you wind up taking pennies on the dollar.  If it's not vintage or cutting edge, no one wants it.

Oh, OK that was yours!  I remember looking at this a few times, and also looking at Lemur and TB MIDI Stuff which both have [partially completed] templates.  Looks really interesting but I never tried it.  Always wondered whether I'd actually really use it after neat factor wore off.

I really like the way Roland approached the "knob issue" on the GT-100 with the multiple screens and endless rotary encoders that control different parameters on each screen.  It's really fast to get to what you want to edit, the knob gives the tactile feel, and they start the change from the current setting rather than making a big jump like on a fixed encoder.  And the LCDs though even though they don't have beautiful graphics have just enough graphical content to sort of make you feel connected to it.

Roland got a lot of things right on the GT-100, IMO.  Shame I don't use it more.  I hope some its good qualities come through in the VG-100 and/or GR-56.  As for BIAS, I should caveat that I like the interface as far as dialing in a preset from the comfort of home.   It would not be very fun to try to spin the touch screen "knobs" in a live situation.  Knobs in an iPad music app frequently don't go the direction I intend them to. :)

QuoteIn my college town, these words are never spoken: "Lets hire the local heavy metal band for our party!"
Heh, so true.  You would have to look hard to find a metal band playing around here, but for some reason if you look in the musician classifieds it would be really easy to join a metal band as they are forming every day.

QuoteSo can I now assume i should be able to realize my dream of using the air+Behringer IS202+Jamup pro+bias+sampletank+loopy simultaneously for live performances? ?

I would not get too carried away with that concept, until real world trials can be performed. IOS7 has new Inter app Audio and the iPad Air is powerful - but managing 4 CPU / memory intensive apps simultaneously  - and more importantly -  having screen real estate for real time User Control to make minor course corrections mid song (without page flipping or multiple app minimize/expand)   - and playing guitar and singing is not my idea of a good time. 

I'm a believer in having plenty spare margin of horsepower at live gigs. But lately I'm playing lots of low volume "open mic"  / 6 acts per night / 30 minute set/ 5 minutes setup time gigs.  So I intend to run Irig Pro interface to iPad Air for Guitar BIAS  / Jamup Pro XT ( possibly with Auria too) and  iPad mini running FTP and Sampletank - both iPad headphone outputs  feed a battery powered,
ROLLS MX44s Mini-Mix IV

For me, metal reached its peak somewhere around 1990 with Metallica's Master of Puppets and Ride the Lightning.  I really enjoyed those albums, and found them to be innovative, progressive, and musical.  Today's metal music seems to be about how far you can drop tune your guitar and getting someone who can do pig squeals to do vocals.  But maybe I'm just getting old.  ::)

One thing is for sure.  When I do happen to see a metal band playing somewhere today, they are always turned up way too loud.  I get it - it's metal and you can't whisper it, but I didn't set out in search of hearing damage either.

Quoteand i will use an IK Blueboard to control Jamup Pro.
Just curious - Is this working out for you so far?  Have you tried using expression pedals with the Blueboard?  For volume or wah control?  The blueboard currently has one review on Sweetwater (http://www.sweetwater.com/store/detail/iRigBlueBoard?device=t&network=g&matchtype=&gclid=CITX14Go-LoCFaFDMgodvkUADQ) and it's not very favorable.

Correct

That why moving forward I feel TBMIDI Stuff holds promise - since it supports bi directional MIDI  - so iPad status indicators should be in sync with reality on the GR-55  - and works with a cheap MIDI cable

So all these things, iPad, Roland GR55 and iRig MIDI are great, except until now they haven't talked both ways...meaning when you change a patch with TB Midi stuff, the current settings weren't reflected in the iPad (ie the GR55 messages weren't getting back to the iPad). Well since the latest TB Midi Stuff update, it NOW WORKS!

I'd previously verified the GR55 was sending sysex by routing it's MIDI out thru my firewire interface through my laptop and using Bomes Send SX and rtpMIDI to send the messages back to the iPad over wifi. Obviously this wouldn't be a great solution live.

Anyway, this is just to prove that it now works! More videos of other templates soon.

Does anyone know if the newer iPad mini-retina has the same processor power and the new full size iPad? 
Thanks Bill

Full Size iPad Air Retina
Built-in 32.4-watt-hour rechargeable lithium-polymer battery



Ipad Mini Retina
Built-in 23.8-watt-hour rechargeable lithium-polymer battery


slightly slower and less battery life - but the form factor is nice - although for many GUI intense control screens the physics of smaller density  = higher odds of finger missing your target.

(I own the 1st gen iPad Mini)

also note the full size iPad Air needs a 12 watt Power adapter


While Mini Retina uses a smaller 10 watt adapter

(10 watt adapter on left vs 12 Watt on right)

This is due to the higher current demands of the larger battery and faster CPU in full size iPad Air

At minimum - get the 32GB version, you WILL run out of room with a 16 GB version.

Compare iPad Air to iPad Mini

Apple's new Retina iPad mini includes the same 64-bit A7 chip used in the iPad Air and the iPhone 5s, which offers significantly better performance than the A5 chip found in the original iPad mini.

According to new Geekbench 3 benchmarks, the Retina iPad mini is running at 1.3Ghz, much like the iPhone 5s. The iPad Air, however, clocks in at 1.4Ghz, giving it a slight performance edge over both the iPhone 5s and the new mini.

(https://www.vguitarforums.com/smf/proxy.php?request=http%3A%2F%2Fcdn.macrumors.com%2Farticle-new%2F2013%2F11%2Fipad_mini_retina_geekbench.jpg&hash=50261e2ff50fb3d06fccc4972a7aa083ed402519)
The Retina iPad mini scored a 1390 on the single-core test and a 2512 on the multi-core test, which was similar to the iPhone 5s score of 1399/2523, and lower than the iPad Air at 1466/2856. Compared to the 261/493 score of the original mini, the Retina iPad mini marks an incredible boost in performance speeds.

It is unclear why the mini is clocked at 1.3Ghz instead of 1.4Ghz like the iPad Air, but in terms of real world usage, users are unlikely to notice the small speed differences. It is possible that Apple chose the lower clock speed in the iPad mini to improve overall battery life or to reduce heat within the smaller chassis.

Apple's Retina iPad mini went on sale last night at midnight and is currently still available from the Apple Online Store and in Apple retail locations via Personal Pickup.

I took delivery of an Ipad Air 128GB 3G today - it flies thru tasks  that stall and halt my old ipad2 cold.

Been playing my bigsby JTV-59 into Sonuus I2M + Apple Lighting USB  Camera adapter as audio interface and Skullcandy Titan II travel buds for headphones with the iPad Air

Positive Grid Bias is really amazing -  I dare to say its a spectacular time to be a guitarist. Bias has very good Clarity, The Amps sound and react very close to the real thing, best Tube Amp tone toolbox on IOS today (Nov 2013) with many controls to satisfy those who crave getting inside, its all emulations of circuits and a  Great amp in the room simulator. I was obtaining great tone in seconds  reminiscent of Ritchie Blackmore playing opening to 'Lazy' off the  Deep Purple Machine Head record. sounds great to my ears  Worth the $19.99, and marries into JamUp Pro XT very well. Very Happy.

Interesting.  Same processor performs slightly better in the larger unit.  Guess they had to slow down the clock probably due to heat dissipation?

Interesting read about BIAS, sounds promising, although some time ago I tried Jamup Pro and while some amp sounded very organic and interesting to me others not where very much of my taste so it was under the impression it would be a bit limiting. The most disturbing thing are the comments about it to be equivalent in quality of the emulations to Kemper  ??? , because I have just ordered one and Im wanting to receive it any day soon!. 
We all know how personal is this matter, I own an AXEFX and used many other amp modelling gear and I yet like very much the Roland amp emulations (VG99 and GR55), but thats another history.
Anyway at this small cost Im thinking about to buy BIAS to my Ipad3, so the question I wanted to ask is: the BIAS amps are better than the Jamup ones? so its redundant to purchase any of the Jamup amp addons? What would be the ideal setup BIAS+JamupXT+effects addons? or with this I'm going to miss something important?

IMHO - yes, more definition, clarity , realism - but thats only what I'm hearing.

QuoteWhat would be the ideal setup BIAS+JamupXT+effects addons?

You Must get a 24 bit ipad audio interface - my current pic is the iRig Pro because this also has a MIDI IN, so I can use any MIDi Foot controller to control BIAS+JamupXT+effects.
http://www.ikmultimedia.com/products/irigpro/ (http://www.ikmultimedia.com/products/irigpro/)
I paid $143 for mine (used some of my IK Bonus points)

I will probably rig up  iRig Pro+iPad into the FX loop on my HD500X  - and use BIAS for all amps, and run a MIDI cable from HD500 MIDI Out to control BIAS+JamupXT.


and realize every few months Positive Grid has a "FX Sale" - I purchased all for 50% off during an Easter sale last spring (I currently own all JamupXT addons)
(learned about these sales here -

Only your ears will tell you.  But I agree with Elantric's conclusion.  I had a similar experience to you.  I liked some of the JamUp amps -others I did not care for.  I did feel that JamUp XT Pro was the best of the iOS amp sims until now.  I am liking all of the amps in BIAS.  They all sound very high definition to my ears.  Not to mention the ability to tweak them to the nth degree.  In my opinion, Positive Grid could take JamUp FX and BIAS amps and roll them up in a hardware box with some high quality I/O and charge KPA/AxeFX prices for them, and get it.  I'm glad they didn't.

I can't say whether the amp add-ons are redundant as I never bought any. Just JamUp Pro XT.  I'm not feeling the need to buy any amp bundles at this point (they may have shot themselves in the foot with future JamUp amp bundle sales) but I will be loading up on FX.  The amps you create in BIAS and export to JamUp stay there.  I haven't compared the amp models in the JamUp expansions to what's in BIAS but seems like there would be a lot of overlap, and I'm not sure the JamUp models would be as good as the BIAS ones.  My ears are telling me that Positive Grid had some sort of algorithmic mega-breakthrough with this product.

I tested the free version of Jamup yesterday and bought Bias today. Great stuff. I only noticed quite a lot of digital noise, both using the VG99 in standard mode through the camera connection kit and using an old behringer interface through the camera connection kit. Not suree what the source of this can be. Any ideas?

Skip the amp bundles but buy the Jamup FX:

* Effect Expansion Pack

* Tube Comp

Its important when feeding a high gain app like Bias to use the best  / lowest noise audio source  / audio interface for your guitar.

So then I suppose that I dont need to purchase any of the amp addons offered by PositiveGrid.
In fact the amps included or the ones offered by in app purchase probably can be done with BIAS or better yet maybe many of the already included with BIAS (it includes a lot, even more than they offer with Jamuppro, right?


Another question I ask myself is: BIAS is based in a general purpose/neutral amp or it has different amp preconfigurations to tweak just like AxeFx do?

If not iRif Pro would be an interesting option, thanks for your informed suggestion.

The "hurdle" is getting the iPad to reconfigure one of the Scarlett 18i6's Mic Inputs to swap to the Hi-z Guitar Input mode.

Rumor Is this can be accomplished if you

1) Connect scarlett-18i6 to your PC/MAC
2) Run the scarlett-18i6 COntrol app  and change a Mic Input to the Hi-z Guitar Input mode.
3) Power down , remove Scarlett-18i6 from your PC/MAC
4) Use an Apple Camera Connection Kit adapter for ipad and Connect scarlett-18i6.

Thanks for your response to my questions, yes that was my impression, BIAS seems to be all we would need in the "amp department" with Jamup, but also it seems a bit strange that Positive Grid has gone aparently against their own interests, thats why I asked, maybe with more time we will see other opinions on this matter and we will have a broader perspective

QuoteIn fact the amps included or the ones offered by in app purchase probably can be done with BIAS or better yet maybe many of the already included with BIAS (it includes a lot, even more than they offer with Jamuppro, right?
It includes 36 factory amp models.  But really my understanding is that these "amp models" are more like presets that Positive Grid has built up using the technologies available in BIAS.  So you could start out with the factory amp model for the '67 Blackface Duo, but then go change out tubes, cabinets, settings, etc. and turn it into the Mark IIc+ model.  And to take it one step further you could create a model for an amp that's not included in the factory presets at all by designing it using BIAS's components.  This could be some other amp that actually exists and that you can buy today, or something that doesn't exist - your own model.  E.g. maybe someone will build a "Splawn" model in BIAS and share it.  Who knows.

Now most of the above is a bit beyond me at this point, other than trial and error, and how well it could work is TBD, but I'm sure some clever person who really understands tube amp design technology will put it to the test soon.  For my level of understanding, all I can really say is that I think the 36 included factory presets sound amazing, and you can sure get some interesting and good sounding results by playing with the controls in each one whether you really know what you're doing or not.

This is the next thing on my list to try.  I don't have a VG-99 but I want to try it with the COSM guitar models on the GR-55, and see how it reacts, because I really do like some of the COSM guitar models, and I don't have all those guitars.  I may try the guitar out port, or maybe the regular 1/4" outs into either the Apogee Jam or Alesis IO Dock (if it will even work with the iPad air and lightning adapter).

For VG-99 folks - dont overlook the FiiO external DAC (SPDIF to analog out)   - might prove to have lower noise compared to feeding a VG-99 Main Analog out into a third party  iPad audio interface.

I've never experienced anything like digital noise in JamUp.  However, when you export an amp from BIAS to JamUp, there is a noticeable drop in level.  I'm not really sure what causes that.  I have not found a way to adjust or monitor input level in JU like you can in BIAS - only output.

I did have some success (and fun) with the combo of BIAS/JamUp, and the GR-55 today.

I tried the GR-55's guitar out and the GR-55's normal line out (mono) into the Apogee Jam interface.  With the guitar out, I really had to turn up the level of the COSM sounds source more than normal.  Usually 50 seems fine, I pushed it up into the 80s.  And then I also got the regular, expected GR-55 guitar out port noise on higher gain amps.

Hooking it up with the normal line out was better.  No noise.  And of course the bonus of being able to do something like put one of the 55s distortion pedals into the signal chain.  Only downside is this would really limit the ability to use the 55 for its own things, in a live situation. 

For that the guitar out seems most appropriate.  JamUp and BIAS both have noise gates so it should be doable.  Still need to try this with the Alesis IO Dock which is what's been going on stage with me lately.  Hopefully it will work with the iPad Air even though the case might not fit it perfectly.  Wonder if anyone's coming out with a musical dock for this model.  Thought I heard Behringer was going to make one with a lightning connector though I'm not sure they ever did...

Explored possible causes of digital noise. Attached an example. Checked out ampkit on my ipad and found my input level to be very low. Ampkit did not have any digital distortion though. Running through a preamp improved digital noise a lot, but it is still not completely gone.

I think JamUp is switching input levels automatically. There is also some form of compression going on. You can hear noise levels coming up when you let a chord ring until it dies out.

Reverb tails are fine though, so it must be something in the (virtual) input circuitry.

Anyone willing to check this out: let a chord ring out on different levels.  I have used the Tweed Lux model of Bias in JamUp without a Noise gate. Do you also hear Noise levels come up when the chord rings out and if you lower your input level on the guitar, can you replicate the digital noise?

Here's the setup tested.  Strat with GK-3 to GR-55 with 13 pin cable.  GR-55 left output to Apogee Jam--> 30/lightning adapter-->iPad.  Sadly, it appears the Alesis IO Dock does not work at all with the iPad Air (or does not work with iOS 7, not sure which).

Created amp in BIAS (Tweed Lux).  Pulled gain down to 5, did not change anything else.  Exported to JamUp, no additional effects in the JamUp chain.  Added JamUp to Audiobus input slot, added Auria to Audiobus output slot to record (nothing in Audiobus effect slot).

GR-55 set up to output COSM guitar only (Strat H&H model, rear P/U, vol 100, tone 100, level 50, GR-55 main volume knob at 12 o'clock.

Thanks for testing. Your recording is definately cleaner than mine. I will explore some other options. I have an old Terratec Phase 26 lying around at work that might be class compliant. If it is, it will fix a lot of problems...

Also I am looking at the iconnectmidi 2+, but it is not available yet in Europe...
Title: Re: Positive Grid BIAS Amp Designer (IOS)
Post by: supernicd on November 24, 2013, 08:30:10 AM
Another take, same basic setup as above.  Reduced the GR-55 COSM guitar volume to 69.  Boosted up the gain on the Tweed Lux model, and the master just a touch.  Rolled off a bit of treble.

https://soundcloud.com/supernicd/jamup-bias-and-gr-55-take-2/s-kynjK

I don't hear what I'm hearing in the track you uploaded, neither digital noise, and I don't think I hear the compression effect either.  Do you?  There is a little bit of noise floor coming from somewhere that you can hear and see in the Soundcloud graphic render, but it just sounds like slight analog hiss.

Good luck!

If you look at the specs it's revealed the iConnectmidi 4+ does a whole lot more, and includes a USB Host port that allows your Korg nanokontrollers or fishman triple play to drive all your 5pin MIDI hardware or Ipad IOS music apps. It's still not released yet but worth waiting for.

But realize no iConnectMIDI box will solve your distortion in Bias/JamUp Pro. It's not an audio interface.

Yikes. That underlying fizz and distortion that rises upon note decay sounds really bad.
  What is your specific Audio signal path ithat is feeding your IPad?

Is this GK3 guitar>VG99> Behringer guitar interface>Apple CCK> IPad?

Or
Is this GK3 guitar>VG99 In Standard USB Audio mode> USB Powered Hub>Apple CCK> IPad?

Just want the details , so others avoid that mess.

FWIW
My Bias/JamUp Pro tones match what SuperNiCd posted here

My path for the recording was my Charvel guitar straight into the Behringer interface - apple camera kit - ipad 2. It improved when I boosted the signal, but still there is a lot of hiss. I left my VG99 in church this afternoon, so I could not test with it.

With the iconnectmidi 2 you can route audio to and from the ipad. Main reason I want it is to use some ipad synths in Cubase. But maybe I will come up with some more options...

Apologies if these are "duh" type suggestions but have you tried the normal iOS troubleshooting stuff:

Just thinking that if you are experiencing this with more than one audio adapter, then maybe the problem is something else.

Post by: sixeight on November 26, 2013, 10:18:34 AM
Supernicd, I have tried all the options you suggested but it has made no difference.

I think the problem is the 16 bit interface. Both the VG99 in standard mode and the Behringer I used are 16 bit interfaces. The distortion you hear is literally the last bit of the audio signal going from 1 to 0.

If you switch the VG99 to advanced mode it is 24 bits, but the ipad does not recognise it anymore. To fix the problem I will need a 24 bit interface.

I think we can conclude that 16 bit interfaces are no good with JamUp/Bias.

I think its fair to add that not all 16 bit interfaces exhibit the severe "fizz" on note decay that you posted.

For example my Sonuus I2M is also 16 bit, but definitely is usable, with none of the "trail of fizz" as heard here:

But its true  - the best solution is a quality low noise Hi-z Guitar / Instrument Preamp coupled to a modern 24 bit A/D convertor driving a USB Audio class compliant interface that passes audio at 24 bits @ 44.1kHz - for iPad compatibility.

I started working alongside PG since the pre-release days of the original JamUp (a free version with 1 amp and just 5 or 6 effects).  I mainly tested amps and effects...gave my input on what they should sound like, how they should react, etc.  I did some marketing, artist relations, offered my services as a tech rep for users, tutorial videos, and the occasional self promoting vids of me using the product :) I am no longer representing the company these days so I really can't comment on future releases, but I thought some videos might help out....because at the end of the day, I'm still a guitarist!

Only audio works on the Terratec, no Midi, unfortunately. EDIT: midi does work. There is seperate firmware for Mac and Windows use. After flashing the Terratec phase 26 with the Mac version of the firmware, midi works!

The audio is completely fizz free. Something does seem to switch back and forth latency wise. The results with the VG99 in standard mode were better latency wise, but I did get fizz there, though it was acceptable on clean amp models...

3) Inside Bias click the icon to launch Jamup Pro XT (upper right on Bias main screen)

4) After Jamup Pro XT  executes and pops up, click the configuration icon (extreme lower right) and navigate the Settings menu to Ultra Low Latency and move the slider to the right to enable this.

I too get the dreaded 'fizz' when using my irig stomp. I will try a better interface but the major problem I have is switching between Bias and JU. I have an ipad 2 and it has completely crashed Bias on one occasion but mostly the audio just gets all garbled and the latency goes through the roof (500mS or so). I have to shut Bias down and restart JU and it's okay. I can still use the amp I created in Bias.

The HD Pro is still not available in Australia from all of the searching I've done. I can get a Lexicon Lambda for $186 and that will get me 24bit audio and midi. The HD Pro from overseas will still set me back over $200.

It seems though, that the iPad 2 is not going to cope with this level of audio processing so I am keen to get an iPad Air.

That wouldn't surprise me.  My general rule of thumb is that a computing device can withstand 1 major operating system version upgrade and still perform well with the current crop of applications.  Two major versions later, even though it may still be on the supported device list, I'm no longer happy with the way it performs with the most recent OS and apps designed for that OS.  At least that's been my general experience, not just with iPads but PCs, phones, etc.

The ipad 2 can only just about cope. A few tips:
- make sure that JamUp or Bias is the only app running
- switch off ultra low latency in JamUp.
- put the ipad in Flight Mode - no bluetooth, wifi, etc.

I am ok with just step 1. I do get the impression JamUp is switching back and forth latency wise automatically...

Congrats on your new Apple iPad Air!


Post your results / opinions.

Realize due to the clarity and accuracy of Bias's Tube amp modeling, you WILL notice the quality (good or bad)  of your Guitar to iPad Audio interface.

Avoid All guitar to iPad audio interfaces that connect using the iPad's 3.5mm TRRS Headset jack as a Guitar Input - you WILL suffer poor results, and white noise, due to the non bypass-able Apple iPad Microphone preamp.

Use a Guitar Audio Input interface that connects directly to the Lightning port works much better.

Then its a short list of guitar interfaces that provide true 24 bit audio into the ipad.

I would say these are the top runners

Yep. Did that. With absolutely nothing else running I get glitching with the sampletank audio into Loopy HD with audiobus. None at all when it runs by itself.

Just tested with Cubasis. Perfect!

I maybe doing something wrong with Loopy...

Matches my own experience actually

I read about folks running 4 separate IOS apps at once using audiobus and loopy HD - maybe they live with the distortion, stutters, dropouts and are deaf?

Wonder if they are paid schills?

Myself - I'm happy to run multiple ipads at once and run cables from iPad headphone outs to a battery small mixer, then to a final iPad running loopy HD 

as I wrote here:

QuoteSo can I now assume i should be able to realize my dream of using the air+Behringer IS202+Jamup pro+bias+sampletank+loopy simultaneously for live performances? ?

I would not get too carried away with that concept, until real world trials can be performed. IOS7 has new Inter app Audio and the iPad Air is powerful - but managing 4 CPU / memory intensive apps simultaneously  - and more importantly -  having screen real estate for real time User Control to make minor course corrections mid song (without page flipping or multiple app minimize/expand)   - and playing guitar and singing is not my idea of a good time. 

I'm a believer in having plenty spare margin of horsepower at live gigs. But lately I'm playing lots of low volume "open mic"  / 6 acts per night / 30 minute set/ 5 minutes setup time gigs.  So I intend to run Irig Pro interface to iPad Air for Guitar BIAS  / Jamup Pro XT ( possibly with Auria too) and  iPad mini running FTP and Sampletank - both iPad headphone outputs  feed a battery powered,
ROLLS MX44s Mini-Mix IV

Then to a stereo volume pedal

and output of stereo volume pedal  feeds a ROLLS DB24 Stereo Direct Interface - to PA

and i will use an IK Blueboard to control Jamup Pro.

I'm still trying out which "rig" suits my needs best - its helps I'm playing many live gigs again with a "normal band" where I want to use these toys  (as opposed the pure vintage surf band for past 7 years where all I required was my '62 Fender Tube Reverb unit.)

Inter App Audio is the way to go right now.  Sampletank with cubasis is pretty slick.  Once you've completed a track...go to the routing and disconnect IAA and turn it back to a stereo track.  This frees up Sampletank to be used in IAA in another track...do this as many times as you want.  Alchemy is another heavyweight on CPU that I do this with....no problems and I'm running a 3rd gen iPad.

I just tried this and whoo hoo! It works beautifully. Audiobus was problematic with some apps like Voicesynth for example. Inter App Audio is much lighter on resources.

* Make a list of IOS Music apps that work together (including routing topology [i.e. Interapp Audio, AudioBus, MIDI Bridge, etc) 
   i.e - which ones play nice with each other

and more importantly (the proverbial "map to the potential minefields")
* Make a list of IOS Music apps that DO NOT work together (including routing topology [i.e. Interapp Audio, AudioBus, MIDI Bridge, etc) 
   i.e - which ones wreak havok with each other

I literally spend hours each day configuring the best workflow that has the smallest footprint for my compositions, so if you guys have questions just email me or I'll try and list results here.  First and foremost, I'm a guitarist so naturally, I focus on that....but I also work with a lot of synth apps and DAWs as well.  I mainly use Beatmaker 2 as a launching pad and then progress to Auria, although cubasis is also helpful in some respects.  If you're not much for midi controller keyboards or hardware...I would really suggest looking into Sonuus G2M for using your guitar as a midi controller.  It's super fast tracking, although only monophonic.  Also, midi guitar is great for polyphonic control (although not as quick on the tracking) I'll try and post some workflow videos in the next couple weeks.  I've devoted the last few years to iOS production so there's not a whole lot that I don't know and am always happy to share my thoughts and help troubleshoot with you. Also, my album "Afterthoughts" (done completely in iOS) is available as a free download for a limited time.  Here's a link.  (Not a whole lot of guitar, but there's some...this was all pre-audiobus) https://derekbuddemeyer.bandcamp.com/album/afterthoughts-remastered just enter a cost of "0" where it says buy or name your price and you can download for free.

I appreciate your input and shared experiences with IOS apps !

QuoteI would really suggest looking into Sonuus G2M for using your guitar as a midi controller.  It's super fast tracking, although only monophonic.

Agreed - i love my similar Sonuus I2M -(the most under-rated  / least understood accessory for guitarists IMHO.) that not only works as a high speed mono Guitar to MIDI interface  - but also happens to work rather well as a 16 bit Guitar Audio Interface for iPad+CCK too.

Ah yes...the i2m.  Sonuus is sending me one.  Should have it shortly.  I really want to check out their G2M v2 interface (because it has a midi out that I think would connect through my griffin StudioConnect). Their app is only $10 and works pretty well with most apps.

Well didn't have much time to fool with Bias. The iRig pro seemed to work very well. I'll have to reread the little manual I could not get Jamup pro to get input. It's gotta be somethin simple I'm just missin
Sound wise I liked some of the factory presets in Bias and thay did seem pretty reactive to both pick and guitar volume controll. I'll get more time with it tommorrow and will hook it up to my Atomic CLR. In my headphones everything sounded a little bassy.

Post by: Ringleader on December 08, 2013, 07:50:01 AM
I agree that the audio interface makes a huge difference with bias. But not just input, also output. I have an apogee jam and yes it sounds great as an input but you are forced to use the stock headphone output on the ipad. I recently picked up an Apogee one and now I can really hear the difference in the output.

Also look at the small roland duo capture as an option. Haven't heard it but almost got it before going with the apogee. It's cheap and has ins and outs so it should be a great option.

Did not realize that there was some sound quality to be gained by not using the iPad's headphone out.  It seems pretty good, though I always worry about the durability of 1/8" connection esp. if you start using for live use.

I've been eyeing the Roland Duo Capture EX (http://www.sweetwater.com/store/detail/DuoCaptureEX).  A little more than the Duo Caputre mk II, but not too much more than an iRig Pro.  Thing I like about this is that it would give MIDI out in addition to in, as well as 1/4" outputs.  Downside is that it seems to need to be powered.  Though it is capable of running on batteries, I wonder how long a set lasts.

I've been using the Alesis io Dock up until now, and having it charge the iPad will really be missed.  But the 16-bit is going to be a deal breaker for BIAS.
Title: Re: Positive Grid BIAS Amp Designer (IOS)
Post by: Ringleader on December 08, 2013, 09:06:36 AM
I didn't know any difference using the ipad headphone out, until I heard the Apogee output on the one. Now I can hear it! The Apogee is more open and clear and it really makes the soft amp experience much more enjoyable, more than I thought it would.

All of my midi devices are midi over USB because I prefer to have each item show up individually in MidiBridge for filters, and because then all you typically need is 1 powered USB hub to power everything. Something to consider anyways.

Based on the power specs on Roland's site, the duo capture shoud require a powered hub but there are reports online that state that no additional power is required when in the tablet mode. I can't confirm, but if this is the case, the duo capture should be a hot seller at that price.

I am running this through the Peavey Ampkit HD and I am getting great results!!!!!!!!  I have been messing around with all the amp sims and have wasted a lot of money on some products but I am in Love with Positive Grid!!!  So much that I might have to get a iPad Air to top it all off....   

Anyway I am glad that I found this forum as you seem to be a nice and knowledgeable bunch of folks here.

Yes, still needs power with phantom power off.  The Roland Duo Capture does not come with a power supply but shares the same one as the VG-99 if you have one.  I am a pretty low level user and don't use high gain tones, and other users might be more discerning than my 64 year old ears but running thru the CCK to an iPad 2 to a Shertler Jam 150 amp using apps such as Garageband, Amplitude, Jam Up it sounds pretty good.  According to the manual the Duo Capture is 24 bit.   In addition to audio I have used the Duo Capture midi from a Roland FC-300 thru the Duo Capture to Loopy HD.  Loopy HD automatically recognizes the Duo Capture.

I don't have one but the iRig Pro looks pretty good also.

I got to spend some time yesterday with Bias plugged into my CLR. It made a huge difference in the sound compared to my AKG headphones. I was pretty impressed with the tones and they react to both pick and volume control. The on thing I did notice on the clean sounds was an apparent sharp plunky kind of tone on the initial attack. I made sure nothing was overdriving anywhere. This is something I don't get with my Kemper at all.
I don't think I would dump my Kemper , but I am impressed with Bias and Jamup pro and will keep working on this. I haven't tried setting up MIDI switching yet, but that would be the next thing.

iRig pro - iPad 2 - Bias - Jamup Pro

I agree.  Bias is impressive, but it didn't win me over vs. the Kemper.  Not yet anyway.  However, I'm still using a 16-bit interface for Bias, so I'm sure there's room for improvement.

Either way, the integration with Jam Up isn't quite as seamless as I'd prefer it.  Especially since none of the amps have reverb modeled in Bias, it's challenging that all the Jam Up effects get dropped as soon as you dive back into Bias to tweak with the amp proper.

I have found the same issue...  working with a nice effects signal chain then I want to go back and tweak the amp a bit but would be nice to still hear the effects chain.  There have been times where I think yes this is it and port it back to JamUp and uggggg.    But then again its new and its fun.  I am sure this will keep getting better and better.

Post by: Elantric on December 09, 2013, 09:58:31 AM
Agreed - I hope Positive Grid may offer better FX integration inside Bias. After you are in Jamup Pro , Editing a Bias  Amp model does prove to be a bit clunky at this hour.

I would pay for a new version of JamUpXT Pro that contained all the new features of the Bias Amps fully integrated.

Regarding comparing gear, as I grow older I tend to go with gear that works reliably and I can navigate swiftly and delivers what I need in the FX department with minimal setup / teardown time - (even if its not the best sounding gear I own.)  I would not place the Kemper in the  "Easy gig Integration" category, for reasons mentioned before. But I do see a place for micstand mounted ipad running Bias/Jamup Pro XT at many of my future gigs.

The big complaint with Kemper is the 40 seconds reboot should an AC power drop out occur. Its like trying to use a Commodore 64 based sampler that must reboot from the 1541 floppy drive at a gig.

Also I tend to use more straight up guitar tones at live gigs, I'm not they guy who needs 80% DSP Alt Tuning  or lots of Synth Tones.

But if it only adds 30 seconds pre-gig setup time for me to integrate an iPad with Tripleplay into my rig, I will use that.

For travel gigs - there is huge attraction for using an all iPad based mobile rig, particularly since I now have a fully loaded Auria DAW  + a Lighting to USB adapter+ powered hub+ 1818VSL, allows me to make live 8 track recording demos of the band on the road. And using Bias+ Jamup pro today is close enough for my needs, but might not be adequate for others.

Yeah, I don't gig any more, but if I did I'm sure I'd lose patience with the Kemper quickly.  It's more at home in a recording studio - and especially as the centerpiece of a home recording studio - IMO.  If I were performing regularly with a band and needed a wide variety of tones, I'd probably be running an HD500 with an iPad in the loop for synths.  I think it would be hard to beat that combo for price, practicality, and tone.

Have you guys tried using anything like this?
Auria:
Bias-noise gate engaged, bypass cabinet
Convolution Reverb-loaded with RedWirez cabinet IR's
Stereo Delay

Very realistic reproductions.
This way you don't lose the tone of your amp (I.e. When you import your amp into the signal chain of Jamup) and you get the realism of the RedWirez cabinets which greatly enhance your sound.

Also works with Overloud THM (available as a IAP in Auria)

Ok so I also decided if my wife is going to kill me I might as well buy Auria along with Bias and Jamup.... :P   I have 100$ left on itunes what else should I get??  any must have Auria Amps?  And really good i0S synths out there?

I don't know. I record a lot with a band that doesn't play live very often so I don't see them very often and I like that better than the 3 or more bands I play out with a lot who like to spring crappy poorly written charts on me at the last minute/call tunes we haven't played for 3 years/ call tunes the new bass player doesn't know / show up 10 minutes before the gig when they are the PA setup guy/ sing tunes we have no business singing in our 50s/ wear questionable clothing/ bring the wife to the gig who can't shut up during your breaks/ bring the wife to the gig who wants to play 20 questions/ bring the wife to the gig.../ bring gigantic PA mains to a 50 seat club that are bigger than the entire footprint of the stage/ the bass player plays with his bass EQd' right in the same are as the guitar frequencies because HE IS ACTUALLY A GUITAR PLAYER!!! etc... etc....I would rather have some ego to deal with if a guy can play well and not do stupid crap like this stuff. Musicians and common sense aren't often found together.

QuoteFYI, for those who haven't stumbled on it, there's a bit more detailed manual for BIAS than what you get with the in-app help here:
http://www.positivegrid.com/bias-help/ (http://www.positivegrid.com/bias-help/)

Positive Grid Bias Manual (part1)

Getting Started
Welcome to BIAS-Amps! A whole new level of tone!
To get started, connect your iOS audio interface to your iPad and plug in your guitar and line output to your headphone or PA system. Launch BIAS app, pick an amp model from the global presets area, and you are ready to go.
The amp control panel will display once you select an amp model, after which you can adjust the amp's basic controls. If you would like to dive deeper, tap on the gear icon to go into BIAS mode and the amp's internal signal path, where you can be creative and customize your amp.
After you edit an amp, save it as a custom preset by tapping the SAVE button in the upper bar. This opens a menu with two choices. Tap 'Overwrite' to overwrite the current preset. Tap 'Save as new' to save your new preset in the CUSTOM amp category. You can also use Quick Presets to instantly save your current settings to one of 8 memory slots; Quick Presets is helpful for doing A/B comparisons during your sound development.       
Use the input and output level sliders in BIAS' lower bar to optimize your signal levels. BIAS also provides a Noise Gate and Room Control to provide a better listening environment, making it easier to get your sound right.
Setups
Headphone

First, connect your guitar interface to your iPad. We recommend using the JamUp Plug from Positive Grid for an interface that connects to the iPad's headphone jack. Alternatively, or you can use one of the many available third-party dock connector interfaces such as the Apogee Jam.  If you're connecting your interface to the iPad's headphone jack, connect your guitar cable and headphones to the interface prior to activating BIAS.  Make sure your volume is not set too high at first.  If you are using an interface for 30-pin dock or Apple's Lightning connector, plug it in and connect your guitar.  Plug headphones into the headphone output of your iPad.  Launch BIAS, and you are ready to go.
Recording

You can record your sound in a number of ways.  On your iPad, you can open your BIAS amp model into JamUp, and then record and overdub your riffs using JamUp's Sampler. You can also record using any other app that is compatible with Inter-App Audio or Audiobus. 
For those of you who would like to record BIAS' sounds straight to your computer's DAW, simply connect a 1/8" cable to the output of your iPad or a connected external interface and plug the other end of the cable into your computer interface (a 1/4" adapter may be needed for this).
Live

For playing live, connect the audio output of your iPad or external interface to a) an amplifier or b) a PA system or mixing board.
You can open BIAS amp models in JamUp and use JamUp live-view, preset and MIDI capabilities for flexible live use. There are a number of pedals available on the market that are compatible with JamUp, including AirTurn pedals and the Griffin Technology StompBox.
Useful Tips

Be sure to put your iPad in airplane mode to prevent incoming messages from interrupting your playing...or blasting an email notification to your audience! It is usually a good practice to keep your iPad's volume set to about 8/10 of it's full range, while keeping the app's volume slider set to just over halfway. If you're playing through an amplifier, connect your iPad to the amp's Effect Return or Power Amp input, or try starting out with your amp on a clean channel and have your EQ set to 12 o'clock. This will give you a good starting point from which you can adjust your overall tone in BIAS.
Basic Operation
Global Amp Presets

BIAS organizes its global amp presets into two categories: FACTORY contains amp models grouped according to the styles of music they are most typically used for. CUSTOM contains user-created amp models.
Tap on FACTORY or CUSTOM, and the display will list all the amp models in that category. Then scroll and tap to select the amp model you want. Once the amp model is selected, the control panel area will automatically update to match the selected model.
Custom User Presets

Any preset can be edited and saved at any time. Tap the SAVE button in the upper bar and then tap Overwrite to overwrite the current preset and save your edited amp in the FACTORY category. Tap "Save as new" to save your edited preset in the CUSTOM area.
Editing Sound

Each amp preset is a complete amp model with preamp, tone stack, power amp, power supply, transformer, EQs, cab and mic, developed in detail and fine-tuned by artists and sound engineers.
Module Local Presets

Before editing a preamp, tone stack, power amp, transformer or EQ, you might want to quickly load a preset for that module as a starting point for your edits. You can find the 'Preset' button on the left side of the module. Just tap it to load or save a module preset.
Exporting to JamUp

BIAS and JamUp were developed together and seamlessly integrated. Each amp model can be imported into (opened in) JamUp with one finger tap. Once imported, the BIAS model will be saved as one of the amp models listed inside JamUp. So, you won't need to reopen BIAS to run that same BIAS model with JamUp again, and you can freely use all the JamUp features such as 8-Track Recorder, Phrase Sampler, Jam Player, Preset, Live-View, and so on with BIAS.
Facebook Share

It's easy and fun to create your own custom amp and let your friends and fans know about it. Just tap on the Facebook icon in the upper bar. You can include a preview image in the sharing window. Log into your Facebook account, write some comments and press the Share button, and it will appear on your Facebook timeline.
Amp Modules
BIAS is more accurate and versatile, and deeper, than any other modeler or processor ever created in hardware or software. This is possible because BIAS focuses only on hardcore modeling algorithms. Also, mobile devices are now capable of delivering desktop-level computing and processing capabilities. The internal processor of the latest iPad is at least 8x faster than the most expensive guitar processor on the market, and it comes with much more memory and a better audio codec. Not to mention the iPad has an easy-to-use, creative and stunning user interface that traditional modelers and processors can't deliver.
The following guide will help to explain the advanced amps controls in order to get you on the road to achieving great tone.
Control Panel Parameters

GAIN - Gain sets the overall amount of input level to the preamp. It's the master gain and distortion control for the preamp section. See the Preamp section for more information.
BASS, MIDDLE, TREBLE - The tone stack controls replicate exactly the gain and frequency response of the selected tone stack topology, including classic passive tone stack and analog parametric tone stack. They match the knob settings exactly to the original amp tone stack topology.
Depending on the tone stack circuit topology, some of the original tone stacks do not have all of the tone controls, while some have more tone controls. For the sake of consistency, we always show three-knob tone controls. You can go into the tone stack module in BIAS mode to fine-tune the original tone stack parameters.
PRESENCE - Presence boosts or cuts the upper frequencies in the power amp module. See the Power Amp section for more information.
MASTER - Master determines the input level, the overall distortion and dynamic characteristics of the power amp module. See the Power Amp section for more information.
Preamp

3-BAND PRE FILTERS
These are custom-designed filters positioned before the distortion tube stages. They can boost or cut the bass, mid and high frequencies before the guitar signal goes into the tube-simulation stages.
For a clean and glassy tone, you can slightly cut the LOW SHELF control and boost the HIGH SHELF control. For a metal tone, cut the LOW SHELF control quite a lot to prevent too much bass signal from going into overdrive (which might cause too much saturation or a boomy bass response), and cut the HIGH SHELF control to prevent distortion from sounding too fuzzy.
Recipes for Great Tones
American Clean: Bass - 4, Mid - 5, High 6.
British Crunch: Bass - 2, Mid - 5, High 4.
British Chime: Bass - 4, Mid - 4, High 6.
Modern Hi Gain: Bass - 2, Mid - 4, High 2.
TUBE TYPE
Ah, tubes. We love 'em, don't we? A quick and easy tube change can make a more interesting and dramatic tonal change—achievable from a single component swap within our amplifiers—than any other besides perhaps a speaker change. It plays the most important role in shaping the distortion characteristics, it influences the interaction between the tube and the circuit built around it, and it generates so many interesting dynamic circuit interactions that are pleasing to our ears.
Based on our MESH MODELING technology, we carefully considered the many aspects of the vacuum tube, including its transconductance curve, bias circuit topology, input and output impedance, internal effect, and much more. You can experiment with using a different combination of tube types to create your ultimate, warm distortion.
Recipes for Great Tones
Ultra clean: 12AU7, 12AU7
American clean: 12AX7, 12AX7
English crunch and high gain: 12AX7, 12AX7
BRIGHT/NORMAL SWITCH
Many amps contain a simple bright cap circuit with a switch that kicks up the upper frequencies. The effect may be subtle or pronounced depending on the overall amp design.
GAIN KNOB
The GAIN KNOB sets the amount of preamp input gain and thus controls the overall preamp distortion. You can use the GAIN KNOB with the MASTER KNOB (see below) to tweak the sound to be clean, slightly broken up, moderately overdriven, or completely distorted.
We also implemented the widely used gain-knob shelving circuit, which gradually increases the bass response when the GAIN KNOB is turned up.
TUBE STAGES
Some modern high-gain amps are designed specifically to create extreme yet controllable preamp tube distortion by cascading multiple gain stages, with gain and master volume controls between each stage to control their individual drive levels. Used in this way, preamp tubes can produce a scorching, harmonically saturated lead tone that sustains all day—what we usually hear as a classic shred or contemporary rock tone—in an amp that relies on its output tubes to amplify the sound rather than add further distortion to it. When driven into distortion in a simpler, more basic amp with fewer gain stages (a category that might nevertheless include some very high-end, "boutique" tube amps), preamp tube distortion becomes just a part of the amp's overall distortion character and is blended with clipping at the phase inverter and output stages (and often at the speaker, too).
The number of TUBE STAGES provides a straightforward yet effective way to instantly manage the overall gain amount. The more tube stages, the more cascading gain stages and the more gain.
Recipes for Great Tones
Solid state: 1 stage
American clean: 2 stages
English crunch: 3 stages
Modern high-gain: 4 stages
DISTORTION
The distortion knob is an extra control that adjusts the amount of distortion in the selected tube stages. It provides greater resolution to fine-tune the distortion—the break-up point—to match various amp designs.
HIGH CUT FREQ (MILLER EFFECT)
In electronics, the Miller effect accounts for the increase in the equivalent input capacitance of an inverting voltage amplifier due to amplification of the effect of capacitance between the input and output terminals.
As most amplifiers are inverting, the effective capacitance at their inputs is increased due to the Miller effect. This can reduce the bandwidth of the amplifier, restricting its range of operation to lower frequencies. The tiny junction and stray capacitances between the base and collector terminals of a Darlington transistor, for example, may be drastically increased by the Miller effect due to its high gain, lowering the high-frequency response of the device.
The HIGH CUT FREQ knob captures the essential Miller effect and uses one simple knob to adjust the amp's bandwidth. The higher the HIGH CUT FREQ knob setting, the less extended the high-frequency response will be in the preamp's tube stages.
LOW CUT FREQ  (CATHODE CAP)
The cathode capacitance adjusts the bandwidth of lower frequencies. The higher you set the LOW CUT FREQ knob, the less extended the bass response will be in the preamp's tube stages.
Recipes for Great Tones
American clean. LOW CUT - 5, HIGH CUT - 1
English crunch. LOW CUT - 4, HIGH CUT - 2
English chime. LOW CUT - 6, HIGH CUT - 4
Modern high-gain. LOW CUT - 6, HIGH CUT - 6
BIAS ADJUST
In order for a vacuum tube to operate in a safe and fairly linear region of its characteristic curve for low signal, the grid element must be maintained at a certain bias voltage. In the real world, properly setting up the bias voltage will prolong the tube's life cycle, and changing the bias point can adjust the characteristics of the tube distortion.
BIAS provides the most accurate simulation of the actual bias circuit. It faithfully adjusts the operation point as in the real world's tube stage, but in BIAS you can experiment with extreme settings without worrying about damaging the tube. Lowering the BIAS ADJUST control will provide a cleaner tone, while higher settings will provide a warmer tone.
3-BAND POST FILTERS
These are custom-designed filters positioned after the distortion tube stages. They can boost or cut the bass, mid and high frequencies after the tube-simulation stages.
For a cleaner tone, you can slightly cut the LOW SHELF control and boost the HIGH SHELF control to create a glassy tone. For metal tones, boost the LOW SHELF control to increase rich bass response, and cut the HIGH SHELF control to prevent the distortion from sounding fuzzy.
Recipes for Great Tones
American clean. Bass - 6, Mid - 4, High 5
English crunch. Bass - 4, Mid - 6, High 6
English chime. Bass - 6, Mid - 4, High 6
Modern high-gain. Bass - 6, Mid - 4, High 4
Tone Stack

The tone stack is a specialized type of audio filter incorporated into the circuit of an amplifier for altering the frequency response of the amplifier. Tone stacks are typically placed between the preamp and power amplifier. They are the most important tonal circuit in most amplifiers.
TONE STACK TOPOLOGY
Each tone stack was designed differently to shape the tone of its amplifier in order to fulfill different sonic applications. Thus, every tone stack plays an important role by shaping the sound for which that tone stack was originally designed. Pick a tone stack topology that's matched to your currently selected amp or get creative and experiment using different, unrelated tone stacks to create your own tone. Here is the description for each tone stack topology:
American Clean
This is the 3-knob tone stack used (in assorted variations) in so many classic amps. Tried and true, it has fairly responsive gain and can create a big scoop in the mids.
American Tweed
Designed for the '50s-era Tweed guitar amps, these tone controls are highly interactive and not very linear—in a musical way! They work extremely well together, allowing you to precisely dial in your sound. Best used for country, blues and rock.
Tweed Bassman
Initially intended to amplify bass guitars, the '50s-era tube amp to which this tonestack was originally matched was also used by musicians playing electric guitar, harmonica, harp and pedal steel guitar—and the sound of this classic tone stack was part of the reason why!
British Top Boost
This classic British tone stack was designed for the seminal "Top Boost" amps in 1959 and was universally adopted in the British invasion by the The Beatles, The Rolling Stones, The Kinks and The Yardbirds. Later, Brian May and The Edge used it to craft their signature sounds. Never strident and always warm-sounding, this is the perfect tone stack for guitarists in '60s cover bands and anyone wanting a beautifully dark, analog sound.
British Crunch
Harking back to the amp stacks used by 1980s-era hard rock and heavy metal bands, these tone stacks pull the midrange band forward with respect to lows and highs, putting a brilliant spotlight on your playing. Used by Anthrax, Judas Priest, Iron Maiden, AC/DC, Bad Company and practically every other hard-driving group of the decade, this is the tone stack of choice for soaring leads and blazing power chords.
British Modern
This modern tone stack has a thoroughly British flavor. Three bands of warm and silky tone. Never glassy-sounding, it's the perfect tone stack for clean and crunchy patches. A Classic Rock favorite!
German Fireball
Precision German engineering meets raucous heavy metal in this tone stack designed for high-performance guitar amps. Think aggressive tone.
American Treadplate
Distinctly American, this custom 3-knob tone stack is tailor-made for rock and metal. Dial in your tone settings and crank your amp's gain to play massively heavy chords!
American 5153
These tone stacks are the perfect match when you're dishing out insane preamp distortion for harmonically rich leads and overdriven rock chords. Their matching amps are identical to those Eddie Van Halen uses both when recording and on tour.
Bass GK
A solid-state classic from the early '80s, this West Coast tone stack produces a dry growl that sounds fantastic on bass guitar.
Bass American
Passive filters are sought after for their round, pure, musical tone. The lack of amplification in their circuits prevents phasiness from polluting their pristine sound. True to its passive origin, this vintage American tone stack delivers the full, warm sound of a classic late-'60s/early-'70s "blackface" rig.
Bass British
This classic 3-band beauty produces the round, musical tone of passive filters. Voiced specifically for bass, its design was a big step forward from previous passive tone stacks, which were typically copied from standard guitar-amp designs and not particularly suited for bass.
Bass Blueline
Widely praised for its fat, clear and punchy sound, this vintage tone stack from 1969 is a leading choice for rock bass players.
Bass Equalizer
Use this tone stack's midrange controls to radically change the personality of your bass guitar. Set the MID FREQ control to 0 for warm, pillowy tones and to 10 to cut through a mix. Sounds great for comping on jazz guitar, too!
Acoustic Equalizer
Three bands of filters that won't impose a strong personality on your sound. The perfect filter set for sculpting clean, natural, woody tones.
Studio Equalizer
Studio-grade filters offering precision control over three bands. When you need to dial in the exact frequency for each band, this is your ticket! Each filter is designed to emulate the response of a classic analog filter. The result is both surgical precision and ultra-smooth sound, useful in applications from mixing to mastering.
TONE STACK CONTROLS
The tone stack control knobs will appear differently depending on the tone stack topology you select.

Read below for details on  "COMPRESSION"

Positive Grid Bias Manual (part2)

Power Amp
TOPOLOGY
The power amp topology plays an important role in shaping the dynamic characteristics of the power amp's tone. It defines at what point the power amp will start to break up, and how it will break up. It might sound subtle, depending on different parameter settings, but you will certainly find the sonic differences to be just like those for the real power amps' responses.
Single Ended
Models the Class A single-ended amplifier. A single-ended-triode vacuum tube amplifier uses a single triode to produce an output, in contrast to a push-pull amplifier which uses a pair of devices with antiphase inputs to generate an output. When going into distortion, it generates a uniquely abrupt distortion.
Split-Load
Models the Class A/B push-pull amplifier with a split-load (also known as "concertina") phase splitter. Its special topology creates the most smooth and rich power amp distortion.
Push-Pull
Models the Class A/B push pull amplifier with a long-tail pair phase splitter. The long-tail pair phase inverter is generally the best choice for a push-pull guitar amplifier. It provides balanced and warm power amp gain structure and very workable headroom.
Solid State
Models solid-state power amplifiers, which use transistors (such as BJTs, FETs and MOSFETs). It creates the cleanest tone possible, with much less distortion than other types of amps. Your ticket for pure and clean tone.
Recipes for Great Tones
American clean. Push-Pull
Small Tweed. Single Ended
Tweed Deluxe. Split-load
Bass and Acoustic. Solid State
Modern high-gain. Push-Pull
MASTER KNOB
The MASTER KNOB was originally designed to simply control the input signal driving the power amplifier. But since the power amplifier is a highly dynamic beast, it's no surprise there is much more to it than just loudness control.
The MASTER KNOB provides one way to control how much power amp distortion you would like for your amp, as it defines the breakup of the power amp distortion. By working with the preamp GAIN KNOB, you can manage the balance of preamp distortion and power amp distortion.
When the power amp section gets heavily saturated, the EQ controls, tone stack controls and presence control will have less influence on the tone and the sound will have a more "bloomy" effect.
DISTORTION
The DISTORTION knob is an extra control for adjusting the amount of distortion in the power amp tube stages. It provides greater resolution to allow fine-tuning the distortion—the break-up point—to match that in various amp designs.
SPLITTER GAIN
The SPLITTER GAIN knob adjusts the distortion in the phase-splitter tube stage. Use this knob to fine-tune the distortion characteristics just for the phase splitter.
POWER GAIN
The POWER GAIN KNOB adjusts the distortion in the output tube stage. Use this knob to fine-tune the distortion characteristics just for the output tube stages.
BIAS ADJUST
This control sets the bias operation point of the power amp. Lower values will create less power amp harmonics, while higher values will create more dynamic harmonics.
PRESENCE, MODERN/VINTAGE SWITCH
The PRESENCE knob boosts or cuts upper frequencies in the power amp stage by altering the negative feedback's frequency response.
MODERN mode creates a sound that cuts more through effects, especially with higher-gain amp types. VINTAGE mode delivers a more classic and balanced upper range.
RESONATE, PUSH/NORMAL
Guitar speakers have an interesting impedance curve shape, which typically has a peak at about 100 Hz and rises gradually above 1 kHz. The speakers interact with the power amplifier through the transformer. The RESONATE knob controls the resulting effect in the lower and upper frequencies. The effect is different depending on the selected power amp tube types and transformer type.
The PUSH switch mode delivers an effect that helps the guitar tone cut through a mix, whereas NORMAL mode replicates a more balanced interaction between power amp and speakers.
Recipes for Great Tones
American clean. Presence: Vintage, 6, Resonate: Normal, 4
English crunch. Presence: Vintage, 6, Resonate: Normal, 4
English chime. Presence: Modern, 6, Resonate: Push, 6
Modern high-gain. Presence: Modern, 6, Resonate: Push, 6
Power Supply

This module has two sections: Power Supply (controls on the left side of the module) and Transformer (Transformer Type selector on the right side of the module).
POWER SUPPLY
This section of the Transformer module models the power supply sag effect. Voltage or power supply sag is a major contributor to an amp's organic sound. The heart of the amp, the power supply is the foundation where the amp's soul is born.
RECTIFIER TYPE (SOLID STATE VS. TUBE)
A tube rectifier has internal resistance. The more current that travels through a tube rectifier, the more the voltage drops. When the voltage drops, the power of the amplifier also drops. This results in an amp with less headroom, but one that provides flattering compression.
A solid-state rectifier has no internal resistance whatsoever. It has a very consistent, fixed voltage drop that occurs both at zero and full current. When an amplifier needs power at low frequencies, there will be no limit to the current that travels through the rectifier. This results in an amp with more headroom for a punchier, more in-your-face sound.
RECTIFIER TUBE TYPE
Different types of rectifier tubes provide different levels of AC-to-DC conversion. The most common small-amp rectifier tube is the 5Y3, used in older amps. This tube works fine in small combos that put out 15 watts or less, but when pushed hard it can start to sag noticeably—great for certain sounds!
At the other end of the scale, the GZ34 (equivalent to the 5AR4 in the USA) has long been considered the king of the rectifier tubes. This powerful, sturdy rectifier tube makes more DC out of the AC it's fed—and does so very elegantly and with great efficiency—while inducing many of the most-loved characteristics of tube rectification in the amplifier's performance.
INPUT KNOB
This knob adjusts the input gain within a +/- 12dB range. The INPUT knob together with the COMPRESSION knob controls when the amplifier will start to sag. Lower settings produce less compression, higher settings more.
RATIO
Sets the amount of compression: the higher the setting, the greater the compression effect.
ATTACK
Sets how quickly the power supply sag will kick in in response to the guitar signal.
RELEASE
Sets how quickly the power supply sag will return to its normal condition.
COMPRESSION
This knob sets the threshold at which the power supply sag will kick in. The higher the knob setting, the greater the compression effect that will be produced.
REDUCTION METER
This virtual analog meter displays the current amount of compression (in dB).

OUTPUT
This knob adjusts the output level within a +/- 12dB range. It provides a way to compensate for loudness increased or reduced by the power supply sag effect.
Transformer

This section of the Transformer module models the response of different types of transformers. The transformer's function is to convert the high-voltage, low-current signal from the amplifier's power tubes into a low-voltage, high-current signal to power the speakers at a low impedance. The transformer is responsible for how efficiently the audio power of an amp will transfer to the load of the speakers, and it prevents hundreds of volts (DC) from passing to the speakers.
An output transformer does not change an amp's character. A different transformer will not change an amp's DNA or make a British amp sound like an American one. It takes what the amp already is, and then enhances it.
TRANSFORMER TYPE
American Style
This transformer produces the leanest bottom end and spotlights the upper midrange, helping your guitar cut through a dense mix with excellent presence.
British Style
Producing a slightly fuller low-midrange band and enhanced highs compared to the American Style transformer, this British classic offers the perfect balance of presence and warmth.
Fat Style
This custom-designed transformer has a boatload of iron in its mammoth core. It extends both the bass- and high-frequency responses and broadens the midrange band, producing terrific saturation and a full, in-your-face sound.

Cab/Mic

The Cab module simulates the tonal response of a guitar-amp speaker and cabinet and the microphone choice and placement on the cab. BIAS' cab simulations emulate vintage, modern, bass and acoustic types of cabs.
CABINET MODEL
Select the cabinet model you want from the drop-down menu. (Tap the down-pointing disclosure arrow to open the menu).
MIC MODEL
Select the microphone model you want from the drop-down menu. (Tap the down-pointing disclosure arrow to open the menu).
MIC X-Y POSITION
X-Y position simulates the mic's position relative to the speaker. You can drag the mic left, right, up or down with respect to the speaker. The closer you move the mic to the center of the speaker, the brighter and more present it will sound. As you move the mic toward the speaker's outside edge, it will sound darker and bassier.
MIC X-Z POSITION - PROXIMITY
The X-Z position simulates the distance of the mic (depicted as a yellow circle) from the speaker. Close-miking produces the classic proximity effect, in which bass-frequency response increases as the mic moves closer.
LEVEL
This slider controls the output level of the Cab module. Use this control to adjust the amp's overall level.

8-Band EQ

BIAS comes with two 8-band equalizers (one in each module), which you can drag and drop to any location in the signal path. Being able to reorder the equalizers with respect to the other modules provides significantly greater flexibility in custom-designing your tone.
The PREAMP, POWER AMP and TRANSFORM modules each provide nonlinear processing; i.e., they create harmonics that are not present in the original input signal. An EQ module will create a different tonal response depending on whether it is placed pre (before) or post (after) one of these nonlinear modules.
Each EQ contains 2 shelving filters (Band 1 is low shelf and Band 8 is high shelf) and 6 peaking filters. You can alternately enable and disable each of them by tapping on their respective numbered button to the right of the frequency-response graph.
FREQUENCY AND GAIN
Simply drag the EQ point left or right to change the center FREQUENCY of the peaking filter; this will change the 6dB-down cutoff frequency on shelving filters. Drag the EQ point up to increase the GAIN of the filter, and down to decrease the gain.
Q
Use two fingers to pinch an EQ point to change the Q from 0.1 to 18.0. This will change the bandwidth of the filter.
Custom Control Panel

BIAS provides an interesting and easy-to-use custom panels feature: Create your own signature amp by changing the name, tolex, grill cloth, panel and knobs. You can even upload your own pic to use as the background graphic for the amp.
Design your awesome amp, and then share to your friends and fans on Facebook by tapping the Facebook icon in the upper bar.
Global Parameters
The global parameters in the bottom bar include those for the noise gate and room control processors. Any changes to parameter values here affect BIAS overall.
Noise Gate

The Noise Gate reduces noise from an input such as a microphone or electric instrument. It is particularly useful for reducing hum or other background electrical noise.
THRESHOLD - Turn the threshold knob until the noise stops or decreases to an acceptable level. 
DECAY -  Decay sets the rate at which the Noise Gate will attenuate the signal once it drops below the threshold. Higher values will make the signal fade faster once it drops below the threshold.
Room Control

Room control simulates a nice room, small to large in size. This gives a better listening experience and simulates a real world-like environment, so you can develop your sound easier.
SIZE - Size controls the virtual size of a room simulation. Increase the Size value to add increased room ambience to the sound.
DAMPING - Damping controls the decay rate of the room reflections.
COLOR - Color adjusts the amount of high-frequency absorption, for a darker or brighter reverb tail.
MIX - Mix sets the ratio of wet (room) and dry (guitar) sound.
Input and output volume

You can control the overall input and output volumes using their respective sliders in the control bar. Adjust the input volume slider to optimize the input level for your particular guitar pickup. To get the best signal-to-noise ratio, drag the input slider so that when you play your guitar the very loudest, the LEDs in the input level meter hit 0dB. The Lock switch for the input-volume slider prevents you from changing the input volume accidentally.
Quick Presets

BIAS offers 8 quick presets for instantly saving the current global settings. Just press and hold one of the 8 slots to save or overwrite. This is a useful tool to help you do A/B comparisons during your sound development or store your favorite amp settings for instant recall.
Global Settings
Global settings affect BIAS' overall configuration.
Input Channels

Choose whether BIAS receives input from the left channel, right channel or stereo input.
Knob Gesture

BIAS provides three knob gestures:
Linear (Vertical) - The knob will respond when you drag up or down.
Rotary - The knob will respond when you drag in a rotating manner.
Auto Detect - The knob will automatically switch to Linear or Rotary mode by detecting your most recent gesture.
Run in Background

Enabling the Run in Background option allows BIAS to continue processing audio when the app is in the background. Disable this option to stop processing when BIAS enters the background. 
Troubleshooting
Q: Why can't I hear sound in BIAS?
A: This might be caused by any one (or several) things:
- You haven't granted permission for BIAS to access your microphone. Go to iOS settings -> Privacy -> Microphone to enable the microphone for BIAS.
- Your iOS audio interface is faulty or disconnected. To rule this out, check to see if your interface works with JamUp or another audio app.
- Your iPad's volume is turned off.
Q: What volume should I have my iPad's volume set to?
A: We recommend you set your iPad's volume to 8/10 of maximum for optimal performance with BIAS.
Q: I've got an idea that could improve BIAS. How should I let you know?
A: Tap the Settings icon, tap on Feedback in the Settings menu, fill out the form and send it to us. We value your input and check out every suggestion we receive.
Q: How I can use a metronome, tuner and record functions?
A: You can use the metronome, tuner and record functions in JamUp. BIAS works great with JamUp. Simply launch JamUp with one tap in BIAS to use both apps at the same time.
Q: Why can't I receive and record audio in iOS 7?
A: iOS 7 introduced a bunch of new security and privacy features and restrictions. When an app wants to record audio, iOS 7 will block the app from doing so until the user gives it permission. Usually this prompts an alert dialog in the app, such as "AudioTest would like to access the microphone." Opening Privacy Settings for the device and enabling Microphone access for the app will solve this problem. The controls can be found in the system Settings menu: Go to iOS settings -> Privacy -> Microphone to enable the microphone for your audio app.

You're welcome but I wish they'd fix it soon. Sampletank has been broken the entire time I've owned my Air and since Sampletank is my bread and butter with the FTP, I've been just sitting around waiting to put the Air through its paces. Hopefully it is updated before my return period expires.

I hope whatever they roll out includes a new Spring Reverb model, or integrated reverb modeling with each of the applicable amps.  I've been digging into Jam Up and Bias a bit more lately, and finding a lot of great stuff (along with some duds, easily avoided) but none of the reverb options really floats my boat.  The Spring reverb module really lacks character (IMO) and kind of sprays a lot of pink noise all over your tone.

EDIT:  whoops, posted before I saw Derek's reply.  In any case... more reverbs please!  IAP would be fine.  :)

And there's more to come! I've been in touch with Calvin Abel, Product Manager at Positive Grid and he's given me a peek into the future:

"We will be launching ToneCloud for BIAS next month, so users can create and share their custom amps," Abel said.

"We think BIAS is a platform, more than a product, think Spotify for tone, tone on the cloud. So, once you are in BIAS, you will have access to thousands of artist/user created amp models, and then we will build social utilities so you can like, follow, comment, etc. This is the idea of building an open platform in this guitar amp/fx space. Instead of buying a product to get 36 amp models, now you get the whole cloud."

Id love to see Positive Grid follow the lead of Wolfgang Palm  - i.e. port their IOS app over to OSX with support as a 64 bit AU in Logic  / Mainstage

http://wolfgangpalm.com/ (http://wolfgangpalm.com/)

better still - offer an alternative to current clunkiness of resorting to Jamup ProXT just to add FX to Bias

Id pay for a "BiasPro XT" with uniform integration.

ToneCloud infrastructure is OK - but based upon amps only without FX, seems ill conceived to me. But what do i know - since bulk of the shared patches on the Kemper Rig Exchange also lacks any effects.

One thing is undeniable, with each passing year iPads are getting faster and faster , which forces one to reconsider if an iPad + a footcontroller+ 24bit A/D interface has already become the ideal platform for a live gig rig for working musicians in 2014

Somebody needs to release a USB class compliant version of NI Rig Kontrol

Cypress Semiconductor has announced a new development kit that allows companies to quickly create audio accessories for iOS Lightning devices. The CY8CKIT-033A PSoC 3 MFi Digital Audio Development Kit for Lightning is being offered to developers for $199, and as the name suggests, it streamlines the process of designing a custom system-on-chip (SoC) solution to process "bit-perfect" USB digital audio data from Lightning devices.

Cypress notes that Apple's Made for iPod/iPhone/iPad (MFi) connectivity specification has become very complex, now running more than 250 pages long with numerous changes and revisions. The CY8CKIT-033A incorporates the latest MFi specifications and is MFi-licensed, letting developers use a software solution to prototype hardware for Lightning audio accessories such as speakers and musical instruments. Over 100 components are found in the PSoC Creator software, which uses a drag and drop interface to lay out the processor's feature; support for Lightning, older Dock Connectors, MIDI and USB interfaces are all included. Developers interested in the Kit will need to obtain an Apple MFi license before buying the kit directly from Apple's MFi web site.

Its the Jamup pro XT's FX which are stereo - (Bias alone is mono only)

Yep. Definitely using Jamup.

Is there a difference between Jamup Pro XT and Jamup XT. I bought Jamup XT a while back and just added the amps and effects to make it virtually 'Pro'. Could that be why my output is in mono?

Yep, Chaztrip, that's the inherent flaw in just about every online user preset sharing system I've seen.  It ultimately gets loaded up with so much content that it's difficult to sift through.  A lot of the content is questionable - maybe it sounded good through the poster's rig but doesn't translate well to yours.  And so downloading presets ultimately becomes many wasted hours.  Rating systems help some but in most cases there aren't enough ratings or enough ratings by people with discerning ears to really make the real gems stand out.  Would be nice if these preset sharing systems allowed for short audio clips so to speed up the selection process.

For the most part I don't bother downloading presets and instead invest the time in finding and going through quality tutorials on how to DIY. :)  I find it's time better spent.

You nailed it here. I need to spend some time going through what each stage or component of the amp and what it does. I mean I know enough at a high level but I would like to know more. I should probably YouTube some of this as I am sure it's out there.  But still love the product and really think that they can take it a it a long way.

Might accomplish that using Audio Bus
and MasterFX

I've also been considering the possibility of incorporating Auria and BIAS for live use.  Auria has some really outstanding FX models available including some included ones, and for purchase (THM, FabFilter effects, PSP, etc.)  My thinking is that you could use the four available track insert FX slots in a chain, one for BIAS, one or more for some pre-amp/stomp type FX (maybe from THM or other), and one or more for 'effect loop' FX, and there's where I'm thinking some of the stereo FX from Auria would really shine.

This needs more exploration.  I'm thinking that different guitar patches could be saved as individual songs (without any recorded tracks).  The trick would be how quickly you could change presets through the File-->Load mechanism.  Might be kind of clunky and slow in a live situation.

And so downloading presets ultimately becomes many wasted hours....  Would be nice if these preset sharing systems allowed for short audio clips so to speed up the selection process.

Or better still, if the browsing/ loading/ testing of presets were fully integrated into the Jam Up UI, and very, very fast.  You really can't evaluate a patch without playing it for yourself, with your own guitar etc.  But if it's a just a question of opening another menu/screen in Jam Up, clicking around, and instantly playing (and subsequently downloading/organizing your favorites) then I'm sure I'll be hooked.  If it's the more typical case of browsing, downloading, organizing, etc. before you even get to play the patch, then I'll stick with DIY as you said earlier.

And if a Mac, PC and/or iTunes are required to download and move presets to the iPad... I won't give it another moment's consideration.

QuoteCurrent the audio output from JamUp is mono.

I'm really surprised to hear this.  I quickly tested the Jam Up rotary sim the other night and was pretty impressed with it; I'm amazed I didn't notice it was mono.  But this might explain - in part anyway - why the reverbs are so uninspiring.

I've just uploaded my Copperhead amp to Tonecloud in Bias... Search DB's Copperhead.  From there, if you have JamUp Pro XT, you can search my DB Orange Crush preset and substitute the Orange amp for the Copperhead and get a pretty good Lynch/DiMartini sound :)

Great idea! I'll give it a go.

I wrote back and asked if they'd create a harmoniser as well. Stereo and an intelligent harmoniser and I'd switch completely to Jamup for my live rig!

Post by: mbenigni on December 20, 2013, 06:43:36 AM
So I'm probably confused here... is Bias Tonecloud a different animal than the "Share" tab in Jam Up?  I tested the latter last night (hadn't noticed it before) but maybe I'm going off topic here?

Anyway: 

QuoteOr better still, if the browsing/ loading/ testing of presets were fully integrated into the Jam Up UI, and very, very fast.

For the Jam Up sharing feature, at any rate, they have pulled this off in spades.  Beautiful UI, instant playable testing, really a step above the sharing options available for other hardware and software modeling packages.  But...

They need to add an option to suppress any presets that include amps/effects you haven't purchased yet.  Otherwise the whole thing becomes a grating marketing exercise, where you poke around fruitlessly being reminded about all the money you haven't spent yet.  Alternately, they could allow for components to be downloaded automatically, as patches demand, in a demo mode that only works in the sharing browser.  This would really be a win-win:  Positive Grid would still be taking advantage of a marketing opportunity, and users could get a meaningful sense of what these alternate amps and effects are capable of.  (I have already learned a few things poking around the shared database, e.g. that the spring reverb I criticized earlier does much better in front of an amp than behind one.)

But as it stands now, it's a little off-putting, and it's an especially confusing situation for Jam Up users who have already invested in Bias.  I'm not in a hurry to buy the dozen or so Jam Up amps required to share presets with everyone else, when Bias will theoretically deliver better amp simulations anyway.

I'm getting more and more acquainted with Jam Up/ Bias though, and I love it.  I have a couple of really good amp sim options now (e.g. KPA), but some of the effects in Jam Up are the best I've heard.  I'm amazed at how convincing the simple analog stuff (like the Dynacomp clone) is, and how good the wah pedal sounds without any tweaking.  The next big step is for Positive Grid to add true stereo options for some of these effects (rotary, room reverbs, digital delay...)


P.S.  Happy Birthday, Steve!  I'm just a couple days before - 12/30.  :)  (And now we're both one step closer to identity theft LOL.)

i often wonder if those among us who are middle aged ( or more) with birthdays close to Christmas suffer the worst gear acquisition syndrome  today

In my case I gave up celebrating my birthday because.

1 Most of my friends are recuperating from new years eve celebrations to remember mine.

2. In my youth, the day always was routine, while the rest of family watched non stop New Tears Day  College football games, I spent too many rainy day birthdays alone with headphones playing guitar on my day off school / work.

After I moved  out, i spent most New Years Eve's performing in a rock band, then head home avoiding a DUI wake up the next morning watch the Pasadena Rose parade, while tuning into the live Radio lampoon broadcast by the Firesign Theater comedy troupe.

And no help that I'm so imaginative with my login name.  ;)  Seriously though, I try not to worry about ID theft all that much.  There are simply too many ways for people to get this info if they really want it.  Easier to keep your eyes open and take immediate corrective measures (e.g. with your bank) if something is amiss.  And try not to be a very big target.  :D  That whole ounce of prevention is worth a pound of cure thing... I find that most people in the 21st century have the opposite problem:  wasting their energy on a ton of prevention.

I've kept up some birthday rituals into middle age, e.g. a nice dinner out with my wife.  But now there's a baby at home so even that's a stretch.  :)  I'd just as soon keep it simple anyway - stay home and keep warm.  :)

Sorry about the friends you've lost.  Good that you took something positive from it.

Happy Birthday Steve and Marc!  I agree, this is one of the greatest forums ever.  I learn so much here, and feel compelled to contribute where I can.  It really is amazing that such a great community can come together, without having ever met in person, out of love of a common interest.

Yeah, the JamUp preset sharing system is a little bit too much like a sales tool for PG for my taste.  Everything I click prompts me to buy something else.  I did buy the FX bundle during the current sale but I'm not sure I want to buy additional amp bundles - seems like there would be a lot of overlap with BIAS.

I really hope someone who knows a lot about tube amp design will come out with a detailed tutorial on tube amp creation in BIAS at some point.  I can read the manual, and can obviously tweak things and hear what impact they have on the sound.  But being a guy who has never designed a tube amp, I'm not sure I have wholistic picture of how all the different components interact with one another.  It seems like there's a lot of power in this app that I'm not quite sure how to harness outside of a trial and error approach.

Post by: mbenigni on December 23, 2013, 07:33:08 AM
Thanks for the birthday wishes, SuperNiCd!

Sounds like we're on the same page re: Jam Up sharing.  I did test out the Bias Tonecloud feature (which is different, i.e. I was confused above) and of course the in-app purchasing prompts are not a problem there, but the lack of integration with any effects is.  In other words, I can't make much sense of what amps might be useful in absence of any effects or even control over volume and tone.  But... the stuff's free, so if you've got time to kill (downloading, navigating and test driving), it's nice that it's there at all I guess.  Personally, I expect to get more mileage just rolling my own.

And yes, some in depth documentation bridging the gap between Bias usage and real-world tube amp design would be awesome!  In the meantime, probably just Google around in search of websites/ forums discussing real amp design (there are at least a few), and see for yourself how much of that translates perceptibly to Bias.  Gotta set aside a considerable amount of time for that, though; it would be a labor of love.

Why would there be latency problems?  I have just about every VST under the sun and I am able to run with my hardware about 256 for buffer and its fine.  I don't see why they would have issues?   Also they will come out with both a AU/MAC....  VST/Windows.

I'm hoping they do something with it.  I tested an early windows edition of JamUp and it was severely crippled by latency and other issues...I hear the Mac version was even worse...so much that they were about to abandoned the idea...maybe they will focus more on vst version now that the mobile stuff is solid.

Myself, Id prefer if Positive Grid spent their energy on making Bias Amps an in-app purchase add on to Jamup -that would deliver one unified IOS app with all the features of Jamup ProXT  but with all the Bias Amps built right in, and offer an upgrade to Stereo FX.


As things stand now - Bias seems half baked without effects, and launching Jamup ProXT within Bias creates an editing hurdle, jumping back and forth between Bias (to select and edit a new amp), and then bounce back to Jamup to add effects, only to have to jump back to Bias to re-adjust the Amp, its a bit of a kludge that only very patient folks will tolerate.

With recent years computers (i7, i5, etc) and with a normal or decent sound card, latency is not a problem in windows (and I think in OSX either). It is perfectly possible to work with a latency of 128 samples (or less if the audiocard is RME or similar) and this is about 3 ms latency, so that is how I use my computers (desktop and laptop) every day without problems.

I hope you do not mind if a give a different opinion about :
After receiving my new Ipad Air and after buying Bias + Jamup I notice some latency when playing (both in low latency mode). Also, and unfortunately (as it seems I'm one of the few who think it) I have not found very exciting the Jamup / Bias sound and emulations, especially for clean, low and medium gain sounds (the hi gain seems more adecuate), for my its nowhere near the quality of the Kemper, Axe-Fx, not even close to the GR55 which each day has me more in love with the fantastic sounds that I can achieve (even de amp emulation) by mixing the 4 sound sources provided.
Even the GR55 portability is wonderful for me if I think about the amount of things that can be done in a small space and the great musicality it brings, I think would be much more uncomfortable with an Ipad + stand +  sound card + adapters +  pedal board. .. seems very cluttered and so far I see no contribution for a better sound quality. A laptop would be much more powerful and versatile...
I tried it but not liked it, sorry.
I only hope that the future VG1000 be a big SUPER GR55

Myself, Id prefer if Positive Grid spent their energy on making Bias Amps an in-app purchase add on to Jamup -that would deliver one unified IOS app with all the features of Jamup ProXT  but with all the Bias Amps built right in, and offer an upgrade to Stereo FX.


As things stand now - Bias seems half baked without effects, and launching Jamup ProXT within Bias creates an editing hurdle, jumping back and forth between Bias (to select and edit a new amp), and then bounce back to Jamup to add effects, only to have to jump back to Bias to re-adjust the Amp, its a bit of a kludge that only very patient folks will tolerate.

     
I agree with that the Bias+Jamup combination is not very elegant and convenient.

Which is cool if you play Metal

I need a nice '64 Fender Deluxe Reverb and '66 Vox AC30 Top Boost, set midway up with good touch sensitivity and on the verge of breakup.

My iRig Pro and Bias delivers these, while Overloud seems more like "Distortion = On / Off" with nothing in between.

:) being a metal player....yes Overloud in Auria and desktop delivers the goods whether I'm in hair metal mode or full on banging my head in a trash can...but, the desktop mode has some really great boutique style amps that put out some pristine cleans and great bluesy tones.  I've been able to achieve the same in the Auria edition...the presets in Auria have the levels cranked...once you back that off, it's a virtual playground.  Don't get me wrong...I love JamUp too but THM has been killing it in recording sessions...I got hired to do some vintage sounding rock tracks for a band last week and this did the trick

Its an Focusrite Scarlett 18i6, with 24 bit 96khz converters and dedicated guitar input, which works good and solid what I tried.

Anyway IMHO, while important to have 24 bit converters I dont think it would make an enormous difference. Maybe would be more noticeable when rolling out the guitar volume where a 16 bit converter can have less resolution but not in other instances. (there has been a lot of effect units and guitar effect units with 16 bit converters and where perfectly good at their time)
Im like you after a good Deluxe, AC30 and similar emulations, but the ones in Bias do not sound very open and fat to my taste. Also the touch sensitivity don't seem to be much noticeable and musical, if i compare with this feature from the Kemper (which is the king at it) its night and day. Don't know where the problem is, but that is my experience at the moment.

Yes yes yes yes!

While I totally support Positive Grid doing desktop versions (and more importantly AU/VST plugins) of their products, I worry that they'll release a desktop "flagship" and subsequently neglect the less expensive mobile product, which will eventually lag behind in features and be treated as their budget product.  I hope that's not the case, because I'm really enjoying the comparative simplicity of working with an iPad instead of a PC.

There is one part of this app that will make your jaw drop and that is the TONE !! . The tones you get out of this app are amazing and sound like you literally have a room full of vintage amps .

I know that if you get this app there is no possible way you will not be impressed with the tone and attention to detail the Positive Grid has put into this app

I love the griffin studioconnect, though.  Even at just 16 bit a to d it still has midi and it charges my ipad.  It is also cheapola (the 30 pin model).  I also don't notice any latency when used in jamup.  Also the gain trim knob is nifty for fuzzing up and driving my guitar signal. 

Also I can confirm that the studioconnect is ipad only.  Did not work on the iphone 4s I tested it on.

The theory is if you update iPhone 4S to IOS7, this will allow StudoConnect to work  - but Ive never tried it .

But indeed the StudioConnect  is worth owning if only for its utility as a 5 pin MIDI I/O interface and iPad Charger. Sweetwater had these on sale for past 3 months @ at $40, but it looks like these are sold out now.

App, Latency-settings & Latency-time:
Bias normal latency 0.028 seconds (noticeable) = 28 milliseconds
Bias low latency 0.016 seconds (acceptable) = 16 milliseconds
jamUp normal latency 0.016 seconds (acceptable) = 16 milliseconds
jamUp low latency 0.010 seconds (good)

I'm wondering if those latency times stack when you run a Bias amp within JamUp, e.g. 16ms + 10ms = 26ms?  I typically launch JamUp and access Bias as needed from there, but it would be helpful to know if the latency is improved by launching Bias alone, when that app will suffice.

I did a search through the thread to see how people are integrating their VG99 with Bias and it looks like there are mixed results. I have my VG99 in the Standard USB mode going to the CCK and into my iPad. I started Jamup and it's not getting any signal. So to trouble shoot I closed everything, started Audiobus, set beatmaker as an input and Jamup as an output. The VG99 comes into a stereo track in beatmaker. This track is picked up crystal clear by Jamup. The puzzle for me is that Jamup, while in this configuration, is able to output to the VG99 no problem.

I know others have had quality issues but what I noticed is that if in the VG99 usb settings you have your in and out both set to the mixer you will get some weird digital feedback. I changed the input (or better to think of it as the return signal) to the ACosm guitar path and that cleared up the noise problems. Again, all this was while using beatmaker as an input and jamup as an ouput via audiobus.

So ultimately I just want to use Jamup/Bias on its own with my VG99. Do you guys think it's just a weird bug or is there no hope for me?

(I'd love to see audiobus 2 have the ability to see audio devices as inputs and outputs!)

I just wish they would fix the "bugs"  - for example after IOS 7.1 was rolled out - my iPad Mini no longer can use  "Low Latency Mode" in Bias / Jamup Pro with out many pops and clicks. So as always -  think twice and check forums before you perform an IOS Update  -else you may end up with a doorstop.

Bias alone has zero parameters that can be MIDI controlled.

it's only when you launch Jamup Pro from within Bias that you achieve a MIDI Control option.
I can use any MIDI Footcontroller, even an old POD XT live works well or use IK Blueboard for wireless control.

Change Jamup Pro patches with MIDI Patch change commands

The top row of effects foot switches switches on the XT Live send unique MIDI CC# commands, which can be mapped to Jamup Pro Stompbox on/off, Delay on/ off, Modulation On/Off, Reverb on/off  - and have expression pedal mapped to  Jamup Pro Volume

Just imagine running two instances of Bias for the dual paths of the VG99. Way cool.

...or using a Bias AU as an insert in MainStage, one amp per channel strip, and having as many amps as your laptop can handle without choking.  I've done up to 10 instances of Amplitube before I ran out of fingers to count them on.

It understood BIAS Amp tone's still rules on IOS - but using several of my Audio Interfaces that allow "Direct Monitor" (Scarlett 2i4, X-Station) reveal exactly what DSP effort it takes to deliver those amazing BIAS tones.

Last weekend I spent an afternoon trying make BIAS work - but wow after editing any BIAS Amps the latency today running BIAS +JamupPro with iPad Air is MUCH higher than it used to be back in January 2014 -


http://www.ikmultimedia.com/products/irigpro/ (http://www.ikmultimedia.com/products/irigpro/)

and many high gain amps in BIAS are pushing audio delay latency up around 20-30 milliseconds with my iPad Air 128GB

For me, the honeymoon period with JamUp/Bias is running a little thin anyway.  Am I the only one who's having a hard time with latency?  It seemed so usable when I first bought it, and I don't know whether that was the thrill of novelty, or whether the app has gotten (much) slower with recent releases, but I can barely play it now, even after a full reset on an iPad Air with no other apps running, in Ultra Low Latency mode.  The latency is distracting for me, and worse, it seems really inconsistent from moment to moment.  It seems like Positive Grid is piling on bells and whistles and assuming Apple will make it all work with a faster iPad 5 in a couple of months.

Maybe I'm doing something wrong, though?  Do you guys run in airplane mode or otherwise disable core OS features to make JamUp playable?

QuoteToday with latest ipad Air and IOS 7.12, the latency on most high gain BIAS Amp models is very high.

I guess it is more likely that Apple's changes to the OS, rather than Positive Grid's changes to the app, are to blame.  I would think PG would be sensitive about optimizing for low-latency, whereas Apple doesn't have any direct interest in the matter.

I haven't used bias in months but are you saying that bias amps used in jamup are higher latency now, or when using just straight bias?

Bias was always too high of latency for me. But bias amps imported into jamup, with no other audio apps running (including bias) and set to lowest latency was ok enough. But if latency is too high when using it like this then something must have went wrong with updates along the way.

This report breaks my trust in ipad software.
We spend money buying and trying out these apps (most importantly hell lot of time installing learning and getting those to work the way we like) only to find that an update has screwed stuff leaving us at the mercy of a further software update!

I was anyway never pleased with any of the guitar apps on ipad for lush arpeggio like cleans with no overdrive what so ever. The higher notes (1st string onwards) always sounded plastic/artificial. Nothing in comparison (only cleans is what I am referring to) to even a simple zoom G1Xon thats just 100$ with a nice looper.

There was a time when I was so overwhelmed by the idea of possibly taking the ipad as my multiFx and amp sim for smaller live gigs and I spent so much time or rather days together trying and buying different apps without any serious guitar playing at all.

I guess it is an addiction and this is pushing me to buy the new Yonac guitar app claiming so many things.  ;D

With my GR55 its so cool and nice to be playing and being creative! It also sounds much better than any ipad software out there IMHO.

Tried JamUp this morning with a Bias amp loaded. At first, it did seem that the latency was a little bit longer and was kinda noticible. So I checked the latency setting and it was set to ultra low. I switched it to low, then back to ultra low and that seems to have brought it down a bit. It is still not as fast as a dedicated hardware multi but I don't think it ever was. Try it and see what you think.

Post by: mbenigni on July 07, 2014, 07:34:04 AM
I had some surprises with regard to JamUp latency this weekend, too. 

First, I bought ToneStack (just the base product at the $5 intro price) and Flying Haggis - impulse purchases really, but I wanted to see if they felt any better than JamUp had the last time I used it. 

Flying Haggis: very low latency, and I love the no-nonsense simplicity about it, from the single-screen UI to the fixed, well-documented CC MIDI programmability.  I.e. have your controller send the specified numbers, done.  Keeps the software simple so there's very little learning curve.  The whole thing is sufficiently spelled out in about 2 pages of text, which includes a nice introduction concerning the developer's design philosophy.  Having said all that, I'm not personally crazy about its tone, and it is perhaps just slightly too simple for my needs: e.g. I could use at minimum a good OD/DIST in the effects chain, and a more flexible reverb.  But if the developer revs. the app to these or other ends, I hope he doesn't compromise his vision of a simple, one-screen amp sim.  It's extremely uncommon these days, and refreshing.

Then I tested ToneStack, and the default Texas Blues tone kind of blew me away - night and day after Flying Haggis.  I turned up the Reverb Mix, turned down the Reverb tone a bit, and was instantly happy.

Then the weird thing:  I wanted a comparison, so I ran JamUp.  And (drumroll please) the latency was.... fine.  I don't understand it.  I tried several amps, and while I was aware of latency (in other words, aware I was running a software modeler), I heard nothing that would have justified my comments of last week. One major variable: on Friday night I installed the upgrade to iOS 7.13, but based on all I'd read, I actually expected that to make matters worse, not better.

So who knows?  Maybe the f/w update purged memory in some way that a cold boot doesn't?  Maybe in a short while JamUp will start acting up again?  Maybe they ALL will?  In any event I bought the ToneStack Motherload and I spent the rest of the week happily working there.  I can't say yet which I like better of ToneStack vs. JamUp.  JamUp allows for deep editing via Bias, but Tonestack wins me over by virtue of one simple feature I'd been looking for high and low:  a tape deck with a continuous pitch control knob - not just semi-tones.  Learning covers recorded in the 50's and 60's, for instance, this is a serious help.

Elantric - I see in your post above that you were running 7.12 as of last week, not 7.13.  Have you tried the iOS upgrade yet, and if so, have you seen any improvement in JamUp latency?  It may be that I spent a lot of money on amp sims this weekend without actually needing to...  Ah well, not the first time, not the last.  :)

I'm def. not running a beta.  It must be that I installed 7.1.2 this weekend and have since gotten confused. (I Googled iOS 7.13 before posting and got results, so mistakenly assumed...)  It's weird that I wasn't notified of the upgrade to 7.1.2. until just this weekend, but anyway, apologies for the misinformation!

Still stands that latency in JamUp was OK during quick testing after the upgrade, but I will circle back and try Steve's step-by-step test ASAP.

Post by: Elantric on July 07, 2014, 11:14:18 AM
At least I have documented the reproducible Steps which bring high latency to BIAS/JamupPro XT.

In my discussions and research on this problem , frankly I'm surprised to hear these comments

1) "In BIAS  - just enable "Ultra Low Latency"
   On my system, BIAS only offers these choices:  "Latency = "Normal" or "Low" - I have this set to "Low"

    Reminder, its over on Jamup Pro where I have these choices:  "Ultra Low Latency - "On" or "Off"  - I have this set to "On"



I was also surprised to discover folks who say they never tried using BIAS along with Jamup Pro - so they never see the problem. Apparently BIAS alone is fine for their IPAD Guitar Amp needs.

I say BIAS remains a  half baked app with no MIDI control and no FX  - its only until you launch BIAS within Jamup Pro that you have a working Live Guitar system - but its annoying that anytime you want to adjust the amp, you must "do the Positive Grid dance"  by heading back to BIAS alone (which disables Jamup pro's FX and "go dry with no FX) anytime you want to tweak amp settings. its not very productive as I need to always go back and forth and back and forth from BIAS to JAMUP, then back to BIAS, then back to JAMUP - and each round of Amp Editing BIAS amps under Jamup Pro renders higher latency 

Title: Re: Positive Grid BIAS Amp Designer (IOS)
Post by: Ringleader on July 07, 2014, 11:22:27 AM
Elantric - Forgive me if I am mistaken, but I still get the impression that you are using both apps (bias and jamup) at once. Once you have created an amp in bias and exported to jamup, you no longer need bias running in order to use the amp. You only need bias for the deep editing.

I see bias as an amp workbench. I create amps and tweak them and test them. Once I like it, I export to jamup and save as a preset. For playing, I only open jamup (not bias) and the bias created amp is in there to be used with jamup effects and lowest latency. If I decide that my bias amp needs a tweak, I open it in bias to test and tweak, and then repeat as necessary.

Thanks - but in my workflow I'm always Adjusting my amp - typically Cab Mic placement and cant do that without BIAS running along with Jamup ProXT.

But I find the BIAS+Jamup documentation for running both together (necessary for my workflow) to be either "Missing in Action" or an evolving array of loose threads of ever changing confusion, rumor and innuendo.

I agree that the schism between Bias and JamUp is kind of a drag.  It would be nice if Bias behaved like any other in-app purchase in JamUp, allowing deep editing if it were purchased, locked otherwise.  Even if that feature incurred latency when in use, at least you'd be able to tweak an amp without having to completely reset your ears vs. whatever effects you were just hearing in context.  Bias and JamUp are awesome, impressive applications, but not entirely practical.

Basically boils down to my workflow - I always continually adjust my BIAS Amp Controls and go back and forth and back and forth from BIAS to JAMUP, then back to BIAS, then back to JAMUP - and after  each round of BIAS Amp Editing, then returning to Jamup Pro  (ALWAYS) renders higher latency

Yes, there is a dramatic difference in tone depending on the mic placement in these vsts.  Before I touch bass/mid/treble, I experiment with the mic placement (and pu selection...) first.  It's much more convincing than tweaking EQ.

Well - Of course today Positive Grid released Updates to both BIAS and JamUpPro XT  and now my ultra Long Latency problem when I re-entered jamup Pro after editing an amp in BIAS is far more acceptible - nothing like the long processing latency delay I had with prior version.


But yes there is I would say 11-16 ms latency on most BIAS amps right now, and in to my ears this gets 3-5 ms longer when you launch these same BIAS Amps in Jamup Pro ( While many report Latency gets lower after you launch BIAS Amps in Jamup, that has NEVER been my experience) - but its more than acceptable now after today updates  - and nothing like the long long delay  BIAS Amp under Jamup Pro XT latency I was experiencing last weekend with old versions.


So Positive Grid is making progress.

My test system

IK Irig Pro

Audio Technica ATH-M50

Ipad Model MF108LL/A

IOS Version 7.1.2 (11D257)

BIAS Version 1.5.0.2282
     DSP Engine 237
     Crash Report Library 2.1
     Latency = Low

Jamup Pro XT version 3.6.0.700
     DSP Engine 237
     Ultra Low Latency = ON

I admit I own these iPad Amp Sims :GarageBand,  BIAS, Jamup Pro XT, Yonac ToneStack, Flying Haggis, Amplitude, AmpKit+ - with all the addons - each has its place in the tone arsenal and buying all is still cheaper than buying an average Tube amp today - But with a Nov 2013 iPad Air 128GB  - latency does exist in varying degrees - and some folks are more tolerant of it, while others will notice it right away.

This is consistent with my current results with an iPad Air.  The initial latency jump isn't surprising since, once you've made the initial Bias edit, both Bias and JamUp are up and running.  (This is a confusing state of affairs if both apps have background audio turned on, but it seems to manage itself OK.)  The latency is subtle now, even to where I find myself questioning the difference.  Even trying, I didn't manage to make it as bad as I recall its being last week.

But it just occurs to me that last week I was playing along with background songs - either in JamUp's tapedeck, or switching between JamUp and the iPad Music player.  Maybe this exacerbates the problem?  I'll have to get back to retest that.

Last night I plugged my guitar into iRig Pro into iPad 2/ 32 gig and headphone out and it sounded like a garbled mess, not clear a lot of noise and somewhat unnatural sounding. Itsounded the same with Tonestack and Amplitude as well.  ??? I'm scratching my head and can't figure it out. Anyone have any ideas :'( Thanks Paul

What is your Guitar Interface?

But know that latest IOS 7.1.2 does not "play" well with older than iPad 3 devices.

We have heard countless rumors this year that Apple is going to release a "larger" iPad though no one knows just how large this tablet is going to be. Rumor has it that the tablet would be called iPad Pro and that it will have a truly massive 12.9-inch display. Once again we are hearing rumors about the iPad Pro release, with a new rumor coming in from Taiwan suggesting that three iPad models will be launched this year, one of them being the larger model.
Apple is expected to launch its new iPads after it goes through with the iPhone 6 launch this September. The company is expected to launch two iPhones models both with significantly larger displays than their predecessors.
As far as the company's tablets are concerned Economic Daily News claims that a new iPad Air and a new iPad mini will be released later this year alongside a 12.9-inch iPad Pro. Apparently the company aims to capture the enterprise and education market with this particular tablet.
Apple is mum about its tablet plans as always so we shouldn't expect to hear anything from the company until the day of the announcement comes. There have been conflicting reports about the iPad Pro in the past though, with some claiming that the company has shelved the project for the time being and may not revisit it until next year.
Would you see yourself opting for the 12.9-inch iPad Pro instead of the conventional 9.7-inch iPad Air? Its not like the latter has not done well in both enterprise and education markets, so is there really a need for a larger iPad?

QuoteWell I was so absent minded as a kid my mom used to pin my mittens onto my coat sleeves. Some things never change and so here's my solution.

That's awesome.  Looks so easy in the demo... but I wonder.  I have a gimmicky slide that's supposed to serve the same purpose - it's basically half a slide, excepting a ring that goes around your finger, and the idea is you rotate it out of the way when you want to play conventional lines.  But it doesn't really fit comfortably or engage/ disengage in any way that's natural to me.  Though I'm sure there's someone somewhere who can make it look easy, too.

I have the brass one and I really like it. I leave it on my finger for long periods of time and I find it to be pretty comfortable most of the time. I get a tiny pinch sometimes when riffing with higher notes like D chord arpeggios and going up for bends at the 22nd fret can be a bit dicey as the jetslide can hit the lower guitar "horn" if you're not careful. On the other hand I use it for light percussion on that same horn and the tremolo arm or whatever else I can think of to bang around on little monkey that I am. I've only been playing slide for a couple of months and so the fairest description of my slide playing is the "cats fighting in a bag" sound but I'm getting better and I really like being able to switch rapidly between fingers and slide even if just for a quick accent.

Yeah I am still using my hardware(GR55/GT10/HD500 etc...) for live gigging but being able to plug my guitar into my iphone and then into a powered speaker which is usually already at the rehearsal place and use my little Blueboard to switch patches has made rehearsals a hell of a lot easier.I even caught myself laughing and relaxing a bit at the last one while the singers screwed around for 20 minutes.I am not updating my iphone period.It works great.My Iphone is new and has IOS7 and I have not noticed any latency problems with Jamup.

BIAS update – Positive Grid bring some iOS8 tweaks
September 26, 2014 by John Leave a Comment
badge appstore lrg BIAS update   Positive Grid bring some iOS8 tweaksbias logo BIAS update   Positive Grid bring some iOS8 tweaksI posted earlier in the week about Positive Grid's update to JamUp Pro and which bought some optimisations for use under iOS8. As I suggested then, I didn't think it would be long before BIAS got the same treatment and v.1.5.3 duly arrived on the App Store today.
The update brings a number of bug fixes and, in particular, addressed a crash issue that effected some users under iOS8. Running BIAS as a stand-alone app on my iOS8 equipped iPad Air seemed to go pretty smoothly once I'd applied the update. Equally, the app launched and seemed to work very well within Cubasis when inserted via IAA.

The only odd behaviour I experienced was when using BIAS via Audiobus. If I launched Audiobus in the normal fashion as my first app, BIAS didn't appear in the app list for the Input or Effect slots in BIAS. However, if I launched BIAS first, followed by Audiobus, then BIAS did appear. Having noticed this for BIAS, I then checked for JamUp and experienced the same thing. In addition, the Audiobus control strip seemed to have a few quirks when I did get BIAS going in Audiobus. Neither BIAS nor JamUp Pro are currently listed on the Audiobus website as being ready for use with Audiobus under iOS8 so maybe there are still some details that Positive Grid are working on on that front?

All that said, I didn't have any problems sonically; in the short tests I've conducted so far, the audio seemed to be fine. There are obviously still a few iOS8/Audiobus wrinkles to be sorted out here and, if my experience is shared by others, then I suspect Positive Grid will be on to it shortly. That said, there was nothing here to stop me working with the app....
And, of course, it still sounds great...  If you have not had the 'build yourself a virtual amp' experience yet, BIAS is an absolute must for any tone-nerdy iOS guitar player (and I can't wait to see the desktop version when it is officially released). Fingers crossed the last bumps in the code will be sorted soon....

This is a waste of money even at $1. It gives random readouts that are useless - sometimes differing numbers for the same pitch, sometimes the same number for lugs out of tune of even different toms. Avoid.

IMHO the cab modelling in Jamup Pro kills my HD500 fizzy cab modelling with no tweaking.Even my Boss GT10 cabs sound warmer and better than my HD500 and I have tweked the cabs on it for a year.The HD500 is amazing into the effect return of a tube amp though but I dont want to carry them around anymore.

I have run BIAS on my iPad mini, iPad 2 and iPhone 5S.

I cannot run in low latency mode on the iPad mini and even in normal mode I get pops and glitches although reasonably rare. When using the iPhone 5S I can run in low latency mode with about the same clicks and pops as the iPad mini in normal mode. I've got to admit though that the iPhone 5S in normal mode is more than adequate.

I do wish I could some how integrate BIAS into my rig as it sounds so much better than anything else I have (GR-55, GP-10, Zoom G3).

Does BIAS accept MIDI PC commands to at least change amp models?

That was my experience too - When BIAS for IOS was first released in 2013, it ran great on my iPad 2 and iPad mini - then around June 2014, after an IOS update - things went south with crackles and ridiculously high latency:

Positive Grid has diverse projects, throw many darts at the wall , then place their resources on clear profit centers.

Latest press releases indicate they are working with Apple to integrate elements of their Final Touch Mastering app for a new AAC standard  - to raise the bar towards higher audio performance

But in a world where the Ik Blueboard sells for $67,  i really doubt their version (Positive Grid BT-4 ) can make an impact or compete

Alone - no

But if you buy Jamup pro - then you can use the MIDI control in Jam Up pro to change Amp Models  -including BIAS Amp Models.

Lack of MIDI control in all versions of Bias are a turn off to me - and my requests to add MIDI Control to BIAS falls on deaf ears

I have Jamup Pro but I find that once I take an amp in Bias over to Jamup it loses something. The effects are mono in Jamup and that is disappointing as well.

The quality is sufficient for live work but I'm finding it difficult to integrate into my band rig. ie GR-55, Voicelive GTX (which I'd like to replace with my VL3), Zoom G3 and EHX Iron Lung.

BIAS update – and huge reductions on BIAS and JamUp Pro
January 19, 2015 by John
Given the powerful combination that Positive Grid's BIAS guitar amp designer and JamUp Pro guitar amp/cab/effects modeller provide, it is hardly surprising that they have become a combination of choice for lots of iOS musicians with a guitar habit. Oh, and the fact that these iOS music apps happen to sound excellent might also help.... :-)
I've also reviewed some of the expansion packs that both apps offer as IAPs (here and here) and, if you are an absolute guitar tone nut, acquiring these sorts of additional 'virtual' kit can become a bit of a habit.
BIAS; working within Audiobus under iOS8.
BIAS; working within Audiobus under iOS8.
Positive Grid have released a minor update today to BIAS for both the iPad and iPhone versions. Version 1.5.9 includes a number of minor tweaks, the main one being fixes to the Tone Stacks control mapping and within the 'Save As' menu functions; both welcome for a somewhat smoother ride.
However, while technical updates are always welcome for existing owners, perhaps the more interesting news is for potential owners. Both BIAS and JamUp Pro are currently 75% off their normal price; both are currently on offer for just UK£3.99. This represents a brilliant deal.
On top of this, there are various IAP expansion packs that are available at 50% of their usual price; if you want to expand your collection of virtual gear then this is also a good time for doing that.
All of these apps are good value at full price; at 75% off they are a complete no-brainer. Both BIAS and JamUp Pro come highly recommended.

I haven't bought BIAS amp and BIAS fx yet. For me, a simple amp and compressor combination would be great. I have seen several screenshots of BIAS amp and I have noticed that the transformer section has a few knobs to tweak compression (including attack and release). I was wondering whether these would suffice or if I would be better of with a tube compressor from BIAS fx. What do you think?

Bump.

As of the 15th, models on the tonecloud made with IRs on PC can be used on iOS. This is a huge upgrade in quality that I fear may have been too little, too late. As someone who's had a few bugged-out IR models he's been waiting to use, though, this has me feeling a little better about investing in PG.

Has anyone heard word of an iOS Bias Amps update schedule?  The Positive Grid apps are the only ones that still (i.e. post iOS 9) give me trouble when I try to run audio to/from USB.  I want to use Bias Amps as an insert loop in my Helix over the USB cable, but it sounds consistently terrible, like a sampling rate mismatch or buffer overrun type of problem.  Every other amp sim I own works fine in this same configuration, but of course Bias Amps is the one I want to use.  Is Bias Amps just that much more CPU intensive (essentially, no longer compatible with 1st gen iPad Air) or is P.G. asleep at the wheel here?

Its a bit of both.

I Know we praised the iPad AIR when it was new , but today its just another 3 year old iPad and becoming a dog as  latest generations of iPads are much faster, and newer versions of IOS become more of a resource pig.

And Positive Grid is too busy on other tasks  - focused on Desktop Plugins and their Hardware Amp 
Ive moved to Yonac Tonestack myself (lower latency, better workflow, Stereo FX, IAA Host, built in Song learning tools, etc)

Strange that Bias Amps will behave well with certain interfaces, and with audio going out to the 1/8" headphone jack, but it chokes with full-duplex over USB.

And it's a shame that I can't run it - it would be the perfect complement to the Helix, many of whose amp models are questionable to me at the moment, but which provides a great platform otherwise.  Bias Amps seems like it would be more streamlined in absence of all of the effects, recording tools, etc. I don't need, and I'd really like to leverage all of the preamp/ poweramp/ tonestack/ transformer tweaks it offers.  (Theoretically, should be doable with an iPhone 6 velcro'd to the back of the Helix, and how elegant would that be?)

So close yet so far.  Same as it ever was.  :/ 

Guess I go back to holding out for the real solution: a firmware fix from Line 6.

Or put a gently used  Atomic Amplifire in a FX loop on the Helix , and use the Amplifire's superior Amp /Cab Tones

The Helix as USB Audio Interface remains "iffy" and not pop & click free on any platform.

Yes, that would definitely work - but it's considerably more expense and bulk.  (More expense in light of the fact that my iOS devices are already paid for, at any rate.)

I would just about kill for a Kemper stompbox with nothing but the amp/cab block in it.  No effects, etc. - just a kipr loader, basically.
