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.

Nodebeat on 2 iPad-s triggering iMPC & iWavestation MIDI - ambient session 001
.... it´s not perfect, because it´s not MIDI synchronized (Nodebeat has no midi in option). But for creating short loops it´s very useful. Another limitation is that i have no time to discover with midi notes exactly go out, so i have only 5 to create drums. But i will work on this. Stay update and Enjoy.
