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.
Korg Module on iOS 13
When I run Korg Module on iOS 12 (on an old iPod Touch) it works fine. But if I run it on either of my two newer iPads (a 10.5 and a 12.9) the latency makes it so sluggish as to be unusable. I’ve checked all the advanced buffer and voices settings. Has anyone else noticed this?
