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.

This is an update for an old app, it's a great Theremin emulation but sadly no IAA or AB yet, but still a lot of fun as a standalone and maybe if it gets some attention the dev may add AB, its from the same dev as Synthdrum Pads and I think that supports AB

Ha, yeah the door creaks as someone enters the room, when I watched it back I thought that fits in quite well
