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.

Wonderful App, indispensable!

I had been getting help on the excellent Audiobus forum for a while, not realising there was also an App of the same name, DOH!

I am just beginning to explore its powers and it’s blowing me away.

Not only does it receive, process and output MIDI and Audio, but many other things as well. The Midi-learn is superb btw.

A super discovery was its ability to run StreamByter scripts in order to do the impossible with all things MIDI.

I am now able to play my acoustic guitar into my iPhone and:

1. Get its audio processed with an amp simulator, along with reverb and cabinet selection etc, etc,
2. Get the audio converted to Midi; both by Midi Guitar 2,
3. Which then sends the Midi to AudioKit’s super Synth One.
4. In addition I run a drum machine, AudioKit’s AR-909, inside AudioBus3.
5. All of these are controlled by the amazing wireless Bluetooth pedal “BlueBoard” from IK Multimedia, using only 4 foot buttons and one external sustain pedal. (There is a spare pedal socket btw)

I’m a veritable one man band, and this is all possible with the help of AUDIOBUS3.

Thank you!

Top banana!

Brilliant app, developer and forum. AB3 has come in useful many times for various reasons for me - at the present I’m just getting into using it in split-screen mode with Koala sampler (a lot of fun to be had).
There is overlap with some other apps and if you’re only looking for one, you could consider other competitors like AUM or ApeMatrix, but I have got more than my money’s worth from AB3 even though I use AUM more frequently.
The app’s stability is maintained to a high level and the developer is very responsive to any issues arising in the iOS ecosystem. Thoroughly recommended.

Great customer support 🥇

Thank you Michael for your fast response and fix, turning off both Multiroute Mode and Measurement Mode in settings (system and app) cured the problems below. I’m now a happy Audiobus user👍

Just purchased Audiobus 3, but using it with Cubasis3 disables the volume buttons on my iPad Air 4 (iOS15), the speakers and headphones are set at one level and can’t be adjusted. I also thought Audiobus would help prevent apps like Nave, iM1, SampleTank plus a few others from going unexpectedly mute! So, at this moment in time I am not really impressed with it.

Strange! But please just get in touch for help. Tap "Get Support" in app or email me at
