I need to share the fact that I was sitting here losing my damn mind because I couldn’t get AUM to actually send midi. It was because I hadn’t hit “play” 
Anyway, all is working wonderfully, and my phone is successfully controlling BIM. Now onto pedals.
This is fun, thanks again ya’ll.
EDIT: I should add that I’m using an IK Multimedia iRig Midi 2 to interface between my phone and the real world (if this is what that is),
