Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.Download on the App Store
Audiobus is the app that makes the rest of your setup better.
Routing audio to separate outputs on iRig 2
I use an iRig2 with an iPod Touch through the headphone jack. I run the Tonebridge app for guitar effects and I play backing tracks with the built-in Music app. I would like to route ONLY the backing track music through the stereo headphone output and ONLY the processed guitar sounds through the 1/4" amplifier output jack.
Not sure if this is even possible with the iRig 2 (I posted this same question on the IK forums as well to see if this device even can support this) but I figured I'd ask this question here too since this app sounds relevant to what I am trying to do.
I want to do this because it is convenient to have all my backing tracks and guitar effects on a single small device and be able to play the backing track audio through the stereo input of my Roland Cube amp whilst being able to play the processed guitar sounds through the guitar channel of my amp so that I can also add amp effects to the signal before it comes out of the speaker.
Right now I have to turn off all of my amp's effects when I'm playing along to backing tracks because adding delays, choruses, reverbs, etc. to the backing track audio + the guitar sounds doesn't sound right as you can imagine.
Thanks for any guidance you can provide!
