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.
LumBeat apps: great - Please make AUv3s of them ASAP for SaveState where MIDI can be output too.
Currently no LumBeat app has AudioBus State saving. So there's no way of saving everything one has set up in a LB app when using it in combination with other apps - say in AB3.
There's an obvious move to AUv3 these days and there would be so much benefit from having the entire range of LB apps available as AU plugins.
(Maybe even just a single plugin with IAPs for each instrument ? )
