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.
How can I crossfade two audio tracks and automate the fade?
Preferably in Cubasis but if you know a technique in another environment, let me know. I know how I'd do this in Reason 12, but for iOS I'm drawing a blank.
I have two audio tracks that I want to fade back and forth between. I'd like to be able to twist a knob or push a slider to blend between the two seamlessly. Then I'd like to automate that knob/slider to either program (or "play" it line and record the automation that way).
