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.
iOS compatible audio interface urgently wanted
could you please tell me what audio interfaces work for you on iOS devices and what features could be used at the same time? MIDI? Analog? ADAT? S/PDIF? WC?
After solving a power issue for a PreSonus AudioBox 1818 VSL, all audio channels are shown, but there's no sound on any of the 18 outputs.
