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 StoreAudiobus is the app that makes the rest of your setup better.

Brilliant! I used to have this same model, but sold it years ago. Great interface, but presets were hard to save.
Too bad Youtube 'destroys' the audio with its super aggressive limiter
Is it AUv3?

That certainly is (a) musical.
A very fine thing indeed. 
(big influence on late 70s me, for sure, ‘Don’t dream it, be it’ etcetera…) Although, pace Frank, there is something to be said for The Madison too…
