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. And control it all with a MIDI controller. 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, MIDI learn, 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

Indispensable pour les musiciens

C’est un outil absolument indispensable pour tous les musiciens amateurs ou professionnels qui utilisent un iPad.
Personnellement, il représente avec Auria Pro, mes deux app de base. J’encourage donc vivement et sans réserve son développement ! Veillez surtout à conserver sa simplicité d’utilisation !

Must have!!

Une app essentielle pour la production musicale iOS, certaines choses ne sont possibles qu’avec Audiobus comme enregistrer certaines apps vers d’autres apps, la sauvegarde state saving, la barre d’outils pour switcher entre les apps, le routing midi... un super forum anglophone également.
