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.

Switch between apps using MIDI controller



  • Switching apps with midi, would be a key feature to streamline using the ipad as a keyboard, with a midi controller. Having a bunch of synths loaded up in audiobus, each on their own midi channel, and just switch channels on the keyboard to change your sound. The app switching with midi would mean you'd be able to hit a button on the keyboard, and be able to edit your synth sound on the ipad.

    Some midi keyboards have the ability to fire a midi program change message, at the same time that you switch presets on the keyboard, so you could set it up to switch midi channel to a different synth on the ipad, and switch the app on the ipad screen at the same time. Slick!

  • AUM + Midiflow until Mainstage come to iOS...

  • I use the akai mpk249. You can program any button to send keyboard commands such as command + tab. It’s very useful for switching between apps or going to the launcher page.
