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.
Am I the only one that dream about using Garage Band not just as output but also as:
Effect: using the various keyboard or the guitar amplifier and effects
Input: using the various instruments of garage band or a real guitar plugged in?
... And am I the only one dreaming about the possibility of have Garage band simultaneously in two positions?
Why can't this be done?
There are some other app that I really would like to use both as input and effects, but Garage Band is quite the only one we really could take advantage of in all three positions!
Best regards :-)
