About Audiobus: Mixer for music apps

Open up new worlds of creative music making possibilities with Audiobus, the musical hub that lets you use your compatible music apps together, just like virtual cables.

Here are some of the things you can do with Audiobus:

Send live audio or MIDI from one Audiobus-compatible app or AUv3 Audio Unit to another. Add effects on top of your favourite synthesizer, and use your favourite step sequencer to drive it. Or plug in your guitar, and create your own effects chain, in parallel with your mic input. Adjust the mix and balance with the mixer. And send the result to your favourite DAW, sampler or looper, or run it out through a multi-channel audio interface.

Integrate your music gear with Audiobus: connect a Bluetooth or wired MIDI keyboard to play a synth or other app or Audio Unit. Or, control your whole session from a foot switch or other MIDI controller using Audiobus' MIDI Learn In-App Purchase. And sync with external hardware with Audiobus' best-in-class MIDI clock.

The possibilities are endless.

Audiobus has a rich community of over a thousand great compatible apps, including:

- Korg Gadget
- GarageBand
- Launchpad
- Animoog
- Loopy HD
- Cubasis
- Auria
- Amplitube

...And many, many more. See the full list at https://audiob.us/apps
