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

Essential iOS app for music making.

An absolutely essential app to tie all your other production apps together, still with support for older devices!

Developer is on the ball and quick with fixes.

Well worth the entry price.

Ahead of the curve

Still best option when it comes to routing audio and midi in IOS. Slow start but well stable now.

Now with version 3 that includes audio, midi and AU hosting there’s no contender for an IOS musician or any electronic musician. Great!
