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.
USB Cable Recommendation
I am building a pedal board to send audio and MIDI to my iPad via a (Uni Brand) USB C hub.
SooOOooOOOoo - I noticed that the USB cable that I have which is a "Fasgear" brand. The cable doesn't go all the way in as you connect it to the USB hub. It works for sure, but it feels weird that it doesn't go all the way into the receptacle. See the Picture.
