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.

    These tutorials are just what I need.

    I'm finally starting to connect with Audulus.

    In addition to the obvious uses as an instrument or effect, I can see myself using this for custom MIDI glue, special purpose audio adapters, and maybe custom controllers - pending more tutorials.
