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 Gadget 2 exits to home page after launch when UMC1820 is connected
I finally got around to reinstalling Gadget on my new iPad Air and to my surprise it won't run. When I launch the app, the screen goes black for a second and then returns to the home page. The app is in the background, but when I try to bring it into focus, it goes right back to the home page. I'm running iOS 13.3.1. Restarting doesn't help. I actually got it to work once by running it through the app store, but I think it was a fluke because it doesn't work that way anymore. Any ideas?
