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.

OT: A one hour Rick Beato music theory lesson with his best ever instructional deals
I was self-taught musically and always wished I would have taken lessons. I personally like Rick’s style and am glad I found his channel.
The deals are on his massive “Beato Book” pdf, as well as his ear training program. The deals are typically for 24 hrs, so they may have already ended where you live, but hopefully you’ll learn something useful from the video...
