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.
AUM - assigning external knob to tempo - edit remove fractional increases...
Been messin' with this and I would like to be able to control the tempo from an external controller knob set to a CC.
Is it possible in AUM? (well I am guessing it is, I cannot figure how yet haha!)
Ok I found how to do this under the MIDI Control and Transport, however it increments in fractions - EG when I try to move from 120 to, say, 121 it scans thought a lot of . steps (120.1, 120.5, 120.76 etc) and even when I get to the tempo it is very difficult to get it rounded out.
