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.
iconnectivity audio4+ versus iconnectivity audio4c?
I want to be able to share midi inputs and audio interface simultaneously with my Windows PC and my iPad Pro. I'm looking at these two devices and wondering if I need to spend $400 for the 4c or can I do what I need to do with a used 4+. I've tried to compare the two online but don't have a clear answer. Thanks!
