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.
Chordjam scale control
I use Chordjam a lot, so I obviously enjoy it. But there’s something missing, or something I don’t understand.
Particularly when using the robot sequencer, it would be nice to be able to change the main key (that selector at the far upper left) using some kind of midi control. So you could let the thing riff for a while in some key, then - as would be normal in composition - modulate it to a different key.
As it is now, you’re kind of stuck in the selected key, and for that matter in the chord type. Yes, you can randomize both, but it would be really useful to control those directly while it’s running.
