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 sync issue!!
Edit This looks like an Aum transport issue, as it lags gradually even using Beathawk as an AU inside Aum.
Listen to this recording, it starts out sync'd up, then by the 2.5 minute mark it is dreadfully behind...
Has anyone noticed that when in Aum using Link, tempo gradually falls behind non-Au apps like Beatmaker, AfroLatin DM, and others? If I stop and restart Beatmaker (or others) it resyncs, but immediately starts drifting again. Takes about 45 seconds to be totally off... I will run tests on Apematrix and see if it is happening there too...
