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.

Hi all. Happy to announce the availability of the first version of the iPad version of MIDISynth-Circuit. Looks like it's on the US store and should ripple around the world within the next 24 hours. There's a couple of minor issues I found today but nothing to stop the release and these'll be fixed when I'm home in a few days time. Going to enjoy a wedding and a few beers over the weekend, so I'll be a bit unresponsive until Tue of next week.
