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.

Music And Measure Theory
Didn't watch the videos, but for me, A is and will always be the "first" note. It's the first letter in the alphabet, it's the tuning reference, A minor has all white keys, so it feels just as "natural" on a piano keyboard as C major.
