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.
Export audio loops with tempo info
I have recorded some audio that I want to trim and mark with tempo metadata so that BeatHawk (and other apps) will see them as loops they can tempo sync.
Bonus points if slice markers can be created/exported with the loop, too.
I have seen an Audio Dabbler tutorial showing how to do it with BM2.
What other apps can do it?
