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.
Did you know Multitrackstudio has this amazing feature.....?
I just found out today that Multitrackstudio can convert audioclips to midi data, either beats or pitched notes! When you drag an audio clip from an audio track to a midi track with the drum editor or piano roll view, it converts the audio to beats or picthed notes, depending on the type of editor view selected! Nice one!
