Audiobus: Your virtual music studio.
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.
AUM MIDI between iPads
I had this working, and it seemed really simple. Now it doesn't and I don't know why.
I have a Novation LaunchControl plugged into iPad 1, controlling AUM. That works fine. I want to also control AUM on iPad 2. In iPad 1 AUM MIDI Routing, I sent LaunchControl to MIDI Control and to Network Session 1. On iPad 2, I sent Network Session 1 to MIDi Control. That worked, too. I think that's all I did.
I updated the iPads to 11.3.1, and now it doesn't work. I don't know if that's coincidence.
I also had MIDIFire talking between the iPads, and that no longer works.
Am I doing something wrong, or did 11.3.1 break it?
