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.

Major issue (MIDI control) in AUM Mixer!
You cannot have more than 127 sessions, as the developer has not implemented the recognition of the LSB midi message... believe me, when you set up sessions based on songs, the slots add up REAL quick!!
So the best you can do as all he has is MSB and PC is 127...you cannot even change the MSB as there is no way in the app you can exceed 127. If you the return to 0 for the next song after 127 (by then using for example, MSB 01 then patch 1 again) it won't let you as that number has already been assigned.
It would appear the MIDI implementation, at least from a MSB/LSB/PC perspective is very basic!
If someone has a way of accessing more than 127 session in AUM, I'd be happy to be corrected and learn how??
