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.
BopPad Midi Mash Makes StreamByter 12 Strike Smash
Sharing some idle work (heavy-lifting done by the marvelous nic at Audeonic Apps):
Input of 4 notes and turns it into 12 output notes, dependent on cc strike position i.e. three radius note zones per quadrant of the bopPad.
The output notes are configured to a GM drum set and have been tested with DrumJam and SampleTank(live mode). Additional cc re-mapping code is included but switched off. (i.e. to remap pressure aftertouch)
