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:

And send the result to your favourite DAW, sampler or looper, or run it out through a multi-channel audio interface.

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.

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.

Extremely Pi%%ed off

With the latest update every session of mine has been removed from the session directory, so extremely aggravating. I want a refund to purchase an acceptable app that isn’t this unstable.

Oh wow what another great find, my presets in all of my synth apps I had made inside of AB are now unavailable, and I’ll tell you, there were quite a few, a right “kick in the teeth” well deserved 1* and if I could go lower I would.

It was most definitely the app as it is only to do with anything that has been done inside of it, may not have been the update as I think I may remember the last thing I had done before updating thinking “oh there is an update maybe that is what the problem is” after updating no fix but the issue arose when I had plugged in headphones and it crashed, would not open after, hence why I had checked if update needed, updated but still would not launch restarted iPad it then opened but still nothing was restored.

Just extremely agitated with the fact every session is gone, a lot of time wasted it seems if it wasn’t for this mishap it would not be a low 1* review but just stating it’s not the app doesn’t make it any better.

That sounds really annoying! I’m sorry to hear it - but it’s not the app doing that; there’s nothing in Audiobus that would explain disappearance of your files. But if you still want a refund, just google “App Store refund” for details.

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
