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.

I'd like to discuss these three utilities. Their strengths, weaknesses, irritations and at the least, how well they do at what they were designed to do.
I have a thread going about how to wrap my head around my setup (ios standalone and ios merged with external gear) and I thought, heck, I can't be the only relative noob to this platform who gets lost in the decision by what to use what app for.
I always appreciate your expertise...
