Just ran across this device:

http://www.apogeedigital.com/products/jam.php

And with GarageBand now available on the iPad (and working really, really well) I wonder if the GR-55 could be a one stop shop of versatility with the ipad to record. Thoughts?

I'm pretty sure the output from the 55 would work with this, even though this input is obviously not stereo.

There are many other options, Basically you need:

iPad
iPad Camera Connection Kit
Any USB Audio Interface which has "class compliant" drivers.

Here's a short list of iPad compatible Audio / MIDI interfaces which work with the iPad , and IOS Garageband using the Apple iPad Camera Kit :

# Behringer UMA25S (audio & MIDI)

# Digitech GNX4 (audio & MIDI)

# EDIROL PCR-1 (via USB Hub, audio interface also works)

# EDIROL UA-25EX (via USB hub, audio only)

# M-Audio Venom (USB audio works well, MIDI a little patchy)

# Novation X-Station (with power adaptor)

# Novation Xio 25 (audio & MIDI)

# Presonus Audiobox USB (audio & MIDI)

# Zoom H4n (audio only)

"Class-compliant USB audio is the key phrase. If the audio interface doesn't require a driver to use on your Mac or PC, it should work with your iPad with the help of the USB camera connection kit adapter.

As for resolution, if iPad is Fully Class Compliant, then it should be able to address multiple streams, up to reasonable sample and bit rates. Your limits will be set by the power of the iPad, the Touch OS API and whether a particular app developer gives access to the settings the API will support. Some dry reading on the actual audio class standard (nerd alert!) http://www.usb.org/developers/devclass_docs/audio10.pdf

At this stage, it should be theoretically possible to make an app like Multitrack detect available audio streams and direct them to separate channels. For example, I've used a heath-robinson audio interface on my Mac for a few years now, consisting of 4x Sony Singstar USB audio adapters, a passive USB hub and some balanced line adapters on the inputs. Using the CoreAudio control, AudioMIDI Setup, I've built an "aggregate device" which I've then used as my input device to Garage Band, giving me 8, simultaneous recording inputs. It works because each Singstar has a unique serial number as part of the device name, and this separates all the streams from each other.

In theory, replace the passive hub with a powered one, and write a routine into Multitrack to identify separate audio streams, plug all this into the camera kit USB gadget, and you should have a portable multitrack recorder. Whether the Harmonic Dog guys want to bother with such an arcane approach is entirely up to them, but it could be done if Apple will allow the code.

The real key to the success of a feature like this would be to find actual 8 channel audio interface products that are driverless (ie "Class-Compliant") and write specifically for a few of the best.

In short, still a bit of work to do from a lot of different people."

Interesting. I wonder if your YRG will work with it too. I imagine it would. I do have the camera connection kit, but I'm torn as to whether I want to commit to carrying extra stuff around, or whether the size of the JAM and MIKE are what I'd want to do. Of course if I'm carrying the 55 anyway, size is less of an issue.

Oh hey dude, I just remembered: when you get your iPad, go to this page:

http://www.theipadguide.com/content/ipad-dead-pixel-test-how/7171269

and use those images to test two things. 1. make sure it doesn't have any dead pixels. 2. use the black image to make sure there isn't excessive backlight bleed. The latter has been an issue with the initial run of devices.

Has any one used apogee jam with ipad for live use?
I have amplitube n garage band on my ipad after lot of good reviews
on amplitube...but it sounds disastrous using the irig...no life in any
of the patches despite using a strat or ibby prestige. I think the culprit
is irig...i hear people practicing with it but i personally wouldn't
practice with it due to lack of dynamics,noise,signal drop etc.

My plan is to be able to use ipad live by having 4/5 good sounding
patches...will apogee jam be good enough???

RE Apogee Jam
http://www.apogeedigital.com/products/jam.php


Try before you buy.


I find the processing latency to be a negative factor with ALL IOS based guitar Amp simulators.

Various guitar to iPhone/iPad hardware interfaces provide varying degrees of latency. The Line6 Mobile in is the worst, Apogee Jam has among the lowest latency. But all options are more like toys to me - due to the latency. I doubt i could use one for live use, as I'm very picky.  Ive tried several interfaces and software titles on iPAD2, and iPhone 4 , and  iPad mini - i always hear about 60 to 120 milliseconds processing latency before sound emerges after you pluck a string.
Rather easy to test this latency for yourself  - run headphones but keep one ear open so you can hear your non amplified guitar. Hear the processing delay.   

The lowest latency is the internal wolfson CODEC Apple employs  - but the IK MultiMedia iRIG type interface feeding the IOS Device Mic  / headphone jack is prone to self feedback on high gain patches.   

Others seem to live with the latency, or do not care about landing notes in the pocket with a live drummer  - I admit  I'm very picky too.

EDIT: Since 2014 Ive been happy with my similar IK iRig Pro - which is similar to Apogee Jam - but adds MIDi Input (for an external foot controller)

Thanks for the very useful info Elantric!!..However I just got my Apogee Jam and yet to try it...But I guess it is again $100 down the drain.. :-[
I was made to believe that the apogee jam and ipad is the way to go for guitarists...But if the apogee Jam also has the latency issue,its been a bad investment! I will post my views after trying it out tomorrow with my ipad2- I have the irig for comparison as well...the iRig has been useless for me as mentioned earlier..its just a toy..and waste of money!
All those thinking of going the ipad way READ THIS THREAD FIRST before being convinced on some flashy great promos on youtube regarding amplitube with irig or apogee or whatever!

On a different note has anyone tried the Digitech ipb10?

Ok...so i tried my newly purchased apogee jam for the iPad..IT IS MUCH MUCH BETTER  THAN IRIG..NO COMPETITION..
I tried the apogee jam with amplitube,ampkit,garage band, jamup and stompbox software on ipad and ampkit sounded the best. But as elantric stated thered still a  small amount of latency which willnot put you out of rhythm but still doesnot please if you are a serious musician..the clean sounds lacked character on all softwares.
I wouldnt even care to practice with ipad as the tone is uninspiring..so ipad has disappointed me big time and even more the reviews on the internet where people say ipad is "great" with all those "great" apps...
Final verdict: if u must use ipad as a guitar multifx for practice,apogee jam is the ultimate interface.still with the lack of tone i am better off practicing with my laptop and boss micro br80.       
We get limited stuff to try out here in india so now i am very sceptical of buying a
Digitech ipb10, unless someone here gives me the confidence :o

Te be clear - indeed ANYTHING is much better than the original iRig that connects to the iPhone / iPad 3.5mm TRRS Headset jack  - Those are terrible!


Thanks for the review on the Apogee Jam.

Your experience with iPad Guitar Interfaces matches my own.

So instead,  In my own case, I found the Fender G-DEC 3 series amps work VERY well for practice, and Audio Interface to Mac,PC, or iPAD with Camera Connection kit.
(More on the G-DEC 3 here)
https://www.vguitarforums.com/smf/index.php?topic=6003.msg40805#msg40805

9 months ago, Amazon.com was blowing these out for cheap  - i got a pair of the Thirty watt models for $149 each and loved them so much , i got the small 15 watt for $99, and keep in the corner of my girlfriends apartment

Of course I'm using the Fender G-DEC 3  for all Guitar sounds and modeling, with headphones connected to the G-DEC 3.

But the remarkable aspect occurs when i run a usb cable from the G-DEC 3 to the   iPAD with Camera Connection kit.
I will run Meteor Multitrack IOS  App  - and be very productive

https://itunes.apple.com/us/app/meteor-multitrack-recorder/id417726727?mt=8



The Fender Mustang Amps and Mustang Floor work as iPad Audio Interfaces too - but i prefer the G-DEC 3 - as these have more features I use - like the looper and SD card backing track and "Backing track" Volume knob (that also works for USB Audio Return)


If you need a more portable package for iPad - look for a Korg pandora PX5D 
http://www.korg.com/px5d
- use the Amp Modeling in the Korg, while you record USB Audio into iPad with Meteor Mutlitrack using the Apple CCK.


These make excellent guitar practice rigs, Amp Simulator with programmable backing drums and bass  / Real Time External Stereo Audio Transposser , 80 second Phrase Trainer, Footpedal Input jack, and (not too well known) the Korg PX5D also works as a stereo IPAD USB Audio Interface for Ipad IOS Garageband, etc  - using nothing more than the PX5D + Apple Ipad Camera Kit USB adapter. (Powered USB Hub is not needed)

I actually like the  Pandora PX5D's Amp Modelling (excellent Vox AC-30 emulation), and the harmonizer works very well too.
More info on the Korg PX5D as Ipad Audio Interface is here:

http://web.archive.org/web/20110603064953/http://wolfewithane.squarespace.com/blog/2011/2/15/gear-pandora-guitar-effects-for-ipad.html

QuoteThough not designed for iPad, Korg's little effects box has a surprise when you open it: It's capable of sending USB digital audio out to the iPad running iOS 4.2.1 through the iPad Camera Connector Kit. For guitarists, bass players (and of course ukulele players) the Pandora PX5D gives you a world-class effects box for iPad with no extra power chords or USB hubs required.

Stratospheric selection.
Pandora does a little different take on effects. Instead of giving you a few classic effects with multiple parameter controls (the trend among multi-effects processors) the tiny Pandora has one parameter adjustment for the dozens of effects ranging from classic to spacey. For those who like less conventional sounds from their guitar, Pandora has the best selection I've seen in any multi box. The one-parameter-per-effect model makes experimenting with effect patches and getting decent sounds an easy process. You have 100 preset effect patches and 100 of your own.

Like all multi-effects processors, Pandora chains banks of effect together. You chose an effect from each bank or turn the bank off. But unlike many units, each bank can contain some unexpected effects for some wonderfully wild combinations. For instance, the Dynamics and Pickup Effects bank includes a ring modulator, octave pitch and a violin effect and the Amp Effects include guitar and bass synth sounds. You'd expect to find these under Modulation effects, but since they're not, you can add them and still have the Modulation bank to play with.

Pandora and iPad.
It was a pleasant surprise when I plugged Pandora into my iPad Camera Connector and discovered that I could get a solid digital signal into Studio.HD. I was able to turn the digital output in Pandora's Utilities up to 100 and not get distortion, as well as have a workable level on some of the quieter effects. Pandora's tiny size and battery power makes it ideal for quick desktop recording with iPad. I tried to use multi-effect pedals through iMic with the iPad, but found them cumbersome, especially when I wanted to tweak sounds or build patches and had to mess with knobs on the floor. Pandora sits right next to my iPad for a simple workflow and quick sound tweaking.

Noise control.
Every multi-effects unit is prone to noise and some of the modes and effects are more prone than others. After tweaking, I've been able to get noise down to an acceptable level in Pandora and can't really say it's any louder than on the BOSS and ZOOM units I own.

The best way to avoid noise in any multi-effect unit is to turn off all banks and then add effects starting with the first in the chain (Dynamics and Pickup Modeling bank) and working to the right. Since noise early in the chain will snowball, you can get a better grip on where it's coming from and minimize as you build the patch. The Noise Reduction control is last in the chain and should be your last resort, since it's basically a gate. At full setting, the Pandora gate is completely closed and noise-free when you're not playing, but it has an unnatural-sounding, abrupt decay. (If you turn off all effects and use Pandora as a straight USB digital audio converter, you'll find the signal to be very clean.)

What it sounds like.
I threw a quick demo together here using uke and bass. The two instruments used here have high-end, passive piezo pickups, so you'll need to take that into account. This is best listened to with headphones.

While your results with a magnetic pickup will vary, this still gives you an idea of the depth of effects you can create. The Risa Solid soprano is an electric uke stick with a Shadow piezo custom made just for it. The Kala UBass is an acoustic bass with poly strings built on a Baritone uke body. It has a Shadow Bridge Bass pickup. Pandora is designed for magnetic pickups and solid instruments, but it does an admirable job processing electro-acoustics with piezos.

Oh yeah, other features.
Most multi-effect units have a arsenal of other features and the Pandora is no exception here.

Rhythm and bass 128 patterns. Chain 16 together for songs.
Phrase trainer Loops a rhythm and bass pattern + an instrument part you can record to play along with. Can also loop a line feed for play along.
Aux In Play along live with your iPod. For practice you can jack audio from your iPad's headphone output.
Transpose Shift audio from the Aux In up or down in steps up to an octave.
Amp/Line out Line or three different amp settings for better match of output level and EQ depending on where you're sending the signal.
Four faves and footswitch Save your four fave patches. Easily call them up by a dedicated button or optional footswitch.
USB send and receive Allows you to monitor your iPad studio app through Pandora.
MIDI in Use MIDI to control the built-in drums and bass.
PC/Mac software Let's you build patches from the desktop.
My take.
My goal was finding an effects box that's small, battery powered and not a floor unit so it can go anywhere with my iPad. The Pandora is way above everything out there that I've tried. Korg did a competent job with all the classic guitar effects, but since they're a synth company, they've added some way-out guitar synth and modulation effects that can turn your guitar into an other-worldly instrument. Pandora is also one of the few guitar effect boxes with a built-in USB audio converter. This is a unique beast for iPad users who have been looking for a simple and clean way to get stringed instruments with pickups into their iPad for multitrack recording using apps like Studio.HD, Multitrack and StudioTrack. With it's own built-in rhythm and bass and loop recorder, it could be used with a Stereo DAW like TwistedWave on iPad to do simple demos as well.

Thanks for the detail info on the px5d..
Actually i own that nasty boy and yes i love it
for what a feature packed unit it is.
I had its younger brother the px4d too but sold that due to lack of use as
audio interface...but the px5d with the usb is a killer..
I have used it effectively for some demos with cubase with good results.
i will now try that with the cck..
However,my dream of using just an ipad as a guitar processor  live seems to be a distant one
And all the money invested in those toy apps gone down the drain

I was just wondering, does it mean that iPad is not suitable for live use due to the latency issues with different guitar software (amplitube,ampkit,GB etc) and hardware (irig,apogee jam etc) combinations?
I was always wondering of being able to use iPad+guitar into the PA directly with ipad doing all the amp modeling+fx..
For most of my gigs, all I need is about 4/5 patches- 1 acoustic sim,1 clean with lush chorus,1 overdriven rhythm and 1 lead sound that's it.
So I was loving the dream idea of mounting the ipad on a stand with a software such as Stompbox with the look of a multifx floor unit and be able to switch patches with a simple touch...

Now where does the problem exactly lie?
Is it the way these modeling software are built? Or is it the ipad platform itself? Or is it the interfaces like apogee jam?
Will this be ever rectified?

EDIT: in 2014 with my iPad Air and iRig PRO running Positive Grid BIAS and Jamup Pro with "ultra low latency" check box engaged  - already played a few gigs with my iPad!

DURING Live Performance   - Im very picky about ANY latency in my guitar rig

If you can live with processing delays, then you may consider using an iPad for live use.

But as I stated above, all  IOS /IPAD Guitar AMP Simulator apps share a common problem for me - processing latency that is very apparent.

Easy to test the processing latency of ANY system - use a headphone on one ear (to monitor the Amp Sim Latency), while your other ear listens to your natural guitar strings "acoustically". Judge the Amp processing delay.

All DSP based Guitar products that employ an A/D  - DSP - D/A conversion process (VG-99, GR-55, GT-100, POD HD-500, Kemper, etc) all have a short processing latency, typically 8 to 25 milliseconds which is OK with me.

I should point out many DSP based products (like KPA and VG-99) have latency that varies patch to patch  - depending on how many active effects are engaged and running at the same time.

This is one reason why the  VG-99 has independent "Chan Delay" controls for each signal chain, to compensate for these latencies and provide the user with a method to eliminate the inevitable phase cancellation that can result when you mix signals with different latencies.

The fastest , lowest latency devices will be 100% analog signal chain - like a Tube Amp, or Clean channel on a solid state amp, or Tech21 Sansamp - these all have instant response / zero latency.

However as mentioned in prior posts in this thread, all IOS Amp Sim Applications when used with an external Guitar Interface box that uses the Apple Camera Connection Kit, or Apple 30 pin Doc connector, or even the latest ones with "Lightning Dock" support  (Line6 SonicPort, IK iRigHD)  all suffer added latency, typically  75 to 250 milliseconds. 250 milliseconds is 1/4 second and That is something I can't tolerate, nor use at a live gig.

Remember,  Recording is a completely different story - because any processing latency can be corrected in post production in a DAW by dragging  / realigning audio tracks to sit in the pocket with drums and eliminate phase cancellations when combining multiple guitar tracks.

Just to be a bit pedantic - are you referring to round-trip late cues in the VG-99 when used as an audio interface in 'advanced' mode?

I'd have a hard time believing that I'd miss 25ms processing delay from the time I touch a fret until I hear the processed sound. Then again, most of the time I'm employing the models it's a COSM guitar into an amp and little else.

I can hear keyboard latency of 20ms when playing VSTi and that is a non-starter for me. Given that the Megatar neck is 'right' next to my ear - I'd be able to pick up a much smaller delay.

So I'd be curious to know whether the end-to-end processing 'in the box' is really that long. Maybe I'm just distracted by my lack of guitar technique. :-)

The " in the box" latency on the VG-99 for COSM is 10-18 milliseconds. It varies depending on how many effects are activated in the specific patch.

aliensporebomb

For me VG-99 works well for me sitting on my desk with my guitar strapped on and monitoring thru my studio monitors.  Even the guitar to midi response on that box I have tuned so well now that it feels like there's no massive disconnect between me and the sound.  My two cents.  This is while monitoring via USB and the faster the PC the faster the response it seems to me.

Many still read these old threads as "the bible"  - and forget to look at the date of the post! Realize Guitar processing is always a moving target, and many here have changed their philosophy 180 degrees in different directions.

Today (Nov, 2013) with my iPad Air running iRig Pro and Positive Grid BIAS and Jamup Pro XT with "ultra low latency mode engaged" - as a tube amp player I feel right at home and very happy with my tones.

Great to know that elantric!
So is time to start saving for an ipad air now.
So 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? ?
Hope there are no crackles and dropouts with the air.

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.)

Lately I have tried an old 2005 Digitech GNX3000,

and this works very very well as an iPad 24bit Audio I/O, MIDI I/O Interface with just an iPad+CCK
