Open up new worlds of creative music making possibilities with Audiobus, the musical hub that lets you use your 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. Or plug in your guitar, and create your own effects chain, in parallel with your mic input. Adjust the mix and balance with the mixer. And send the result to your favourite DAW, sampler or looper, or run it out through a multi-channel audio interface.

Integrate your music gear with Audiobus: connect a Bluetooth or wired MIDI keyboard to play a synth or other app or Audio Unit. 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.

The possibilities are endless.

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

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

...And many, many more. See the full list at

MIDI Hardware Control

The new IAP makes it easy to control all aspects of your Audiobus sessions with your MIDI hardware and be able to easily recall your setups. With MIDI learn, you can easily mix and match MIDI hardware plus this also works with Bluetooth MIDI too. Audiobus 3 will remember specific controls for specific pieces or MIDI hardware in each preset. You can easily create templates for your MIDI controller setups and put in various synths, filters, eq, and effects as desired.

I like to use a foot pedal to start/stop play plus being able to mute/bypass audio/MIDI app sources in a setup allows for great flexibility in performances or for dialing in sounds without having to navigate screens.

Being able to use an iPad in conjunction with an iPhone to use MIDI apps which take advantage of the phone’s built-in sensors is very useful for controlling multiple parameters simultaneously.

The Very Best For My Workflow

When it comes to communicating between music apps, Audiobus is the best. I will be the first to admit that I have a very simple workflow, not relying on multiple effects to create my sounds. I prefer to adjust my sound in the app itself. With the addition of the IAP of Midi Learn for only $2.99 I free myself from having to use the on pad controls, using my Midi Control Surfaces instead. Start, Stop, Switch between apps, Mix, Adjust; all these and more are now at my fingertips. Ableton Link insures everything is in time. And with one of the most robust support communities at the Audiobus forums you just can’t go wrong.

A must have for all iOS musicians

If you own a couple of music apps that support Audiobus and especially if you own a few Audio Unit intruments or effects, you are doing yourself a big disfavor if you don't own this app yet.

It puts all the pieces of the audio routing puzzle together and lets everything jive together as a perfect matching ensemble. And version 3.1 takes it even a step further with the great new workflow improvements.

I started out with Audiobus years ago but at some point when AUM got released I moved away from Audiobus. However with version 3.1.1 and the improved and very solid support for Audio Units it has drawn me back into the Audiobus camp and feels like returning home. Thanks to the developer's fantastic support it also fixed a couple of technical issues i was having and everything now plays like a dream.

Highly recommended app. Get it now if you don't own it yet!
