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.
I plan to use my iPad on stage, not with too complicated setting (iMidiPatchbay as Midi Router). Due to testing by myself and another thread here I saw, that only few synth apps support patch change using Midi Prog Change et al. So iPad Synthesis is still faily limited in live situations.
So would it be possible to switch presets in AudioBus using Program change?
Or maybe you could implement preset switching in your SDK, so that devs like that of iMidiPatchbay could start a preset change remotely?
Or could at least the preset popup be made permanent visible/visibility toggleable? So one could switch patches easier.
Also it would be great if Audiobus would start apps automatically upon preset loading.
I've bought some synth without the possiblity to switch patches using Midi, this money was wasted...
