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 Studio was my first DAW on iOS. Kind of stopped using it for reasons unknown to me. The sounds are really great though. I used it as a sound module for a live performance a couple years ago. Worked out great. Now that I have a large capacity iPad, I have put it back on and going to fiddle with it soon.
