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.
TC-Data + Gestrument?
TC-Data is a breeze to get working with most every synth I've tried... Nave, Animoog, Magellan, Z3TA+, ThumbJam, SampleTank... Having lots of fun. Huge time suck. This does not get old. More than a great app, this is an important app. But for the life of me, I can't seem to get it to work with Gestrument!
Can't find Gestrument's Background Audio toggle, even though app description & updates in the App Store say it's supported. I really want to leverage it's SoundFont capabilities, ostensibly a different orchestral instrument in each of it's eight banks, with a touch gesture & motion mapping patch in TC-Data. Can this be done?
