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.
Using overdub on looper with Roland AC 33
I have FS 6 footswitch, single cable to looper. 'A' pedal stops, 'B' pedal records, then press B again I get overdub for just a short time. The B pedal is set to momentary not latch. Can't seem to control length of the 'overdub' . Any ideas out there please on how best to use the looper and overdub.
