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.
Set up Toggle Simple Mixer view with Midi or an onscreen button?
Ok I am just diving into loop and setting up some stuff. Reading through the manual I know I can tap and hold for a moment the button that you tap to bring up the mixer, and it will toggle the simple mixer on the loops.
I want to put a button on screen to do the same. In a live enviroment, especially with an iPad pro 2017, 12.9" that has touch screen issues, I do not want to rely on tapping a small button to quickly adjust the volume of a loop.
I searched around the midi bindings and really did not see anything that would togged that mode on and off.
