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.
I bought hardware and connecting it makes my brain hurt
I've bought a Roland TB-3, and now I have absolutely no idea how to actually connect and use it with my iPad (Pro / USB-C), if anyone here has one and has some pointers it would be much appreciated. Can this thing do audio and midi over the USB? At the same time? Do I need to buy a mixer?
Currently I have the USB on the TB-3 connected to an Anker thunderbolt hub, and USB-C connections out of that going to an Audient ID4 and the iPad. None of my apps seem to be able to see the TB-3 though, and I can't seem to send midi to it.
