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.

Dance of the Hidden People - Or, what happens when you get hypnotized by the Moog Model 15
Really had fun with this. Recorded entirely with Garageband on an iPad Pro 12.9 this weekend.
In addition to the Moog Model 15 AUs, there is of course Beat Sequencer, and I just couldn't help myself and had to put in the cinematic strings sustained chord near the end. 
Actually, Garageband is pretty good. My two main gripes: 1) Track volume automation is SO frustrating to use precisely, and 2) "Optimizing performance.................................." o.O
Anyway, here 'tis:

You made some nice, uplifting sounds with that Model 15!
I’ve had a similar fun weekend with GarageBand, but I agree, the volume controls/automation are frustrating to try to control with precision. I hope they fix that.
Keep up the good work!
Ooooooh. Me likey. My teen daughter was walking by when this was playing and she stopped and commented on how cool the drums are. She stood there listening and grooving for about 30 seconds and then danced away.
Thanks! I guess most musicians know that feeling of liking what you just made yourself but you have no idea what anyone else will think.
So nice to hear that others have liked it too!
@obijohn But it's a much bigger deal than that. You managed to grab my kid's attention with your music. My music seems to float away unnoticed most of the time.
Cool piece!
