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.
Send MIDI messages to Playbeat 3 inside Audiobus 3
I currently have Playbeat 3 running as an audio unit inside of Audiobus 3. Playbeat has a midi learn functionality, and I'm trying to map its parameters to my midi controller (an Akai Midi Mix). How do I route this properly? I know I am sending midi to the iPad as when I click on the Playbeat icon in Audiobus, click "send midi message" and press a button on the controller, it successfully shows the note value in the "listening to Midi" field. But how to I pass that message onto Playbeat?
