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

Send live audio or MIDI from one Audiobus-compatible app or Audio Unit to another: add effects on top of your favourite synth, use your favourite step sequencer to drive the whole lot, and record it all in your favourite DAW, sampler or looper. Plug in a MIDI keyboard, run it through an arpeggiator or a key quantizer, and record the result in your DAW, or drive several different sound generators with a keyboard splitter. The possibilities are endless.

Then save your setup in a preset to be restored with one touch later on.

With a completely new MIDI routing system, support for Apple's new Audio Unit Extensions standard, a new built-in mixer, and huge new workflow improvements, Audiobus 3 represents a big step forward for mobile music making.

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

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

and many more. See the full list at

What’s New

Version 3.2.7

Audiobus now provides a Virtual MIDI Bridge output for sending to apps that don't support Audiobus or IAA MIDI like GarageBand. This version also enables network MIDI input and output. Other improvements:

- Fixed an issue with effect lag associated with bypass mode
- Fixed an issue where using the system audio input in one of multiple pipelines to an output app could result in audio lag or silence
- Fixed left/right edge screen lag for AUX keyboard
- Fixed an occasional crash when switching presets with the same AU present, and sped up preset switching
- Fixed a crash caused by some strangely-behaving effect apps

Mostly good, aside from listed compatible apps

So, I’m absolutely not complaining about audiobus itself, in fact, it’s like the greatest thing to be made for iOS.
Here’s my main beef, you guys seriously need to cut out like a large amount of apps listed to work w audiobus, I’ve wasted like 200 bucks on apps that don’t work period, or no longer work w audiobus. You should basically delete everything that hasn’t been updated in the last year, because most of those apps don’t work, or are molesting cpu usage due to coding incompatibilities w iOS 12 on 3rd gen iPad Pro and or audiobus 3. It just seriously would make someone interested in getting into iOS production give up quickly depending on the persons will to throw money at a wall and hope at least a couple apps that work come out. Seriously, narrow that list, it looks wonderful that there are so many apps that you can integrate but that is not currently how real life works after you pay for these apps. Even the Moog stuff is unusable, half the sugarbytes stuff, etc,etc,etc. oh and throw the ruismaker dev some cash because he’s the only reason I keep trying apps at this point, every one of his apps function flawlessly in or out of audiobus, and he’s the only one w a fully functional suite of apps as far as I know at the moment.
Thanks for making one of the best apps, just think about the way it looks to advertise these poopy devs apps that don’t care about customers and refuse to update or remove and keep taking our money, and like I said, these are advertised on your site, it doesn’t make you look good to people who used that list and purchased from it.
Devs blame ios12 but some apps have been updated in last 3 weeks and are now fine, so, not sure what kind of lame excuse that is.

Indispensable for me

Connects virtually everything to everything. Simple and solid. It’s the first app I launch when it’s time to play and/or work. Finally had to write this review to say thanks for helping me make music like never before.
