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.
Using the effects slot of AB like a guitar pedal board?
I want to be able to use my guitar and amp, with the ipad and digital interface and AB in between, processing effects and functioning as a pedal board. Is it possible run my guitar through AB using only an app in the effects slot? It seems to me that when I tried this before it required me to use a guitar modeling app like Tonestack, Bias, and the like as the input source.
