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.
Midi and audiobus
When I use StepPolyArp or genome to control Sunrizer, audio comes out of sunrizer but is not recorded into Loppy. I have Sunrizer in the input slot and Loopy in the output slot. I've tried with and without background audio in Sunrizer. It works fine when I manually hit the keys in Sunrizer.
When I use Soundprism pro to control another app (I.e. Arctic Keys), then put Soundprism in the input slot, Loppy will record the original Soundprism audio, not the controlled audio. It seems that when midi is involved, there is a difference in what I hear in the speakers and what Audiobus hears and records. Is it technically possible to have Audiobus hear the same thing I'm hearing?
