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.
Keeping Loopy Pro and Modular Clock in sync
I am using loopy pro with modular via an es-8 interface. It works great. Im not that pleased with how I am keeping things in sync, however, which is via ableton link and a Circuit Happy ML:2 module. It works, but its not super tight.
What are other people doing to maintain sync?
It would be amazing if Loopy Pro could watch for transients on a channel to ‘tap tempo’, but wont put that on the roadmap if anyone else has a good workaround.
