BIAS for iPhone Requirements

iPhone 4S, iPod touch 5th gen and newer

From the Guitar interface list above - I suggest avoid all except these

and remember that since IOS7 - all iPod Touch and iPhone with Lightning dock will also work with my favorite IOS Audio /MIDI interface setup

actually the line6 sonic port is pretty good. Good build quality, dedicated outputs and the option of stereo input.

I have a different opinion of Sonic Port and Frankly all Line6 IOS Audio interface efforts - these all suffer the highest Latency delay and not in the same league of low latency as iRig HD iRig Pro, Apogee Jam

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.

That's where I grabbed mine!  Also I can confirm additionally that even with iOS7 it's a no go on iphone 4s

Thanks for the confirmation!

Bit of (useful?) info for anyone interested on Latency times using the bias/jamup app:
Tested using 16Gb ipad air ios7.0.6 with 'roland duo-capture ex' usb interface

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)
= 10 milliseconds

mbenigni

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.

Elantric

Answers to this Bias+Jamup latency question should occur here first:

I'll post results as the latency data is available

Latest version of BIAS (Version 1.1.4.2080) has problems,  I'm getting different results depending on the iPad Model used:

Positive Grid BIAS
App Version 1.1.4.2080
DSP Engine 21
Crash Report Library 2.1.5
============
Interface : Irig Pro

IOS: 7.0.4 (11B554a)

Ipad Air128GB (WI-FI+4G(AT&T))(Model MF018LL/A) = Clean Audio, zero anomalies

Ipad Mini 32GB (WI-FI) (2012 1st version)(Model MD532LL/A)= Random Pops, stutters, anomalies

I have sent a report with all info above to Positive Grid
http://help.positivegrid.com/hc/en-us/requests/new

EDIT:
Positive Grid replied today : For iPad Mini "Disable Ultra Low Latency Mode"

mbenigni

That's not good news.  It sounds like they're fattening up the codebase at the expense of latency.  What (positive) changes was the new version meant to introduce?

Well, at least they weren't overly verbose.  :)

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!)

It looks like a desktop version (Windows/Mac) of Bias is on the way.

really excited for this! I'm going to be having neck surgery soon and won't be carrying my rack for a while (therefore KPA stays home).

Very interesting news.  But with all of these different versions of Bias at our disposal, I wish Positive Grid would make some kind of statement comparing the sound engines between them.  I.e. can we expect the desktop version to sound better or worse than the iPad version?  Same question: re: the iPhone version.  And what features are added/ cut from each of these versions to best suit their respective platforms?

Elantric

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.

For the guys who are using BIAS live with their I-gadgets, what are you using to change patches, activate effects etc. Thanks!
