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.Download on the App Store
Audiobus is the app that makes the rest of your setup better.
Blueboard and Sustain Pedal?
The Blueboard manual says that you can plug in either footwitches or continuous controllers to its external controller input jacks. I have been able to use it with a continuous controller (an expression pedal), but it doesn't detect any of of the footswitches or sustain pedals that I have tried (including one with switchable polarity).
Is the manual just wrong?
Has anyone used a sustain pedal as an external input?
Mine has the latest firmware (it is a unit without the mini-usb connector).
