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.
OT: Apple Swift Playgrounds - learn to code
This was posted on iPad Musicians and I thought it might be useful for anyone, like me, thinking about learning to program iPads. The course is very basic but fun, focusing on problem solving in a game style. It requires iOS 10, a 64bit iPad and is about 300mb, but its free! It could be your first step in an amazing 'journey' ha ha!
