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.
How do I use Network MIDI as an input in AB3?
There used to be a "Network Session" that would show up as an input from time to time, often not when needed and for no specific reason would it work or not. But now, it never shows up at all. How do I use Network MIDI as an input in AB3 when it doesn't show up in the list in MIDI inputs?
So far the only way I've figured out is to use the IAA version of an app instead of the AU, since I can't get the AU versions to accept Network MIDI in AB3.
