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.


StreamByter is a powerful scripting language for writing MIDI processing scripts from Audeonic. There is a standalone app called MidiFire that lets you create and use StreamByter scripts as well as an AU that can host them. MIDI Designer Pro can also make use of StreamByter scripts.
