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.

Thanks for keeping us in the loop Jo. I'll send some good thoughts your way. Great to feel valued isn't it?
I really hope it's nothing too serious. But, just in case, bring him his iPad, and a handheld mirror. Hook the iPad up to the wi-fi. He should be able to squeeze out a few more preview/review videos that way.
