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.
Pre or post fader fx bypass
It's great being able to use a midi controller to click fx on and off in Audiobus. But the problem is that the bypass button is after the effect, so when you click it your lovely long reverb just gets chopped off. Most Au effects don't have their own input levels, or bypasses so you have to use your mixer, which in this case is Audiobus. In AUM there is an option to use effects post or pre fader. Can this be acheived in Audiobus I wonder?
