Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.

Patterning + Audiobus issue...
Hey all,
I have an iPad Air running iOS 9.0.2 and an iPad 4 running iOS 8.4.
My iPad Air will let me use Patterning in Audiobus. The iPad 4 will not. It will not show on the list.
The previous version of Audiobus let me use Patterning.
When I try to load a save state in Audiobus with Patterning, it will work.
But Patterning does not show up on my available inputs list...
Can you help?

Try opening the application first, then Audiobus. If you're quick it usually shows at the top before it loads all other supported apps. Just a workaround though.
