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.

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.

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.

Do I need this app?

Do I need this app? Not really. But being a semi pro musician, the curiosity got to me. The flexibility this app offers me from routing midi source, au instrument, au effect, then routing to DAW or external interface inputs is amazing. I’ve also downloaded tons of free or low cost synths, effects, sequencers that has allowed a new area of playing and recording.
Audiobus is now the first app I open before I start playing anything, it is that important in my music workflow.
Do I need this app? Most definitely.

Thank you!

Dunno why I bothered..

I used abv1 a little back in the day. V2 borkt functionality but support wouldn’t have it. (Ouch). so I got off the bus eventually as i couldn’t take anymore. Went for all in ones (blip!blip!) instead and found myself more productive. realised having to open at least 3 odd apps inc. ab was just eh.. people sing its praises well bully for them. But ok, v3 deserves an nth chance what with new bellhickies and whistledoolallies? Nah. This inspires me ios stats report this as “used - never”. as an aside, i suspect littledahls aum will be similarly befuddling...but its clear fannadores of ab/aum enjoy complexity oops sorry “options”...each to their own and stuff..
