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 Store
Audiobus is the app that makes the rest of your setup better.

As always, everybody's feedback is welcome. I'm hoping to join the song of the month club, but I take too long. I finished this one finally because I have been at home on paternity leave the past two weeks. I say screw sleeping when the baby sleeps, that's music time. My obsession with this one was coming up with a good mix, which is something I've really struggled with.
