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.
AU instruments: remembering patches
I’m using 3 different ISEM patches for a track. All loaded as AU instruments. I don’t have any issues doing this initially but when I come back to the track the next time after app has been closed and reopened all ISEM tracks are using the same patch which is whatever seems to be the last patch I used in ISEM. This happens in both NS2 and BM3. Am I doing something wrong or is this just a limitation on iOS at the moment?
