Well it looks like I can create an aggregate midi device in Midipipe and combine the behringer foot controller and the Megadrum and have them both come out of one port. There is Applescript capability in midipipe, so I'm sure there is a way to write code to listen for the midi signal from the behringer and then have a series of conditionals that will modify the midi notes being sent from Megadrum.
Problem is I don't know a damn thing about Applescript. I know PHP and that's about it for programming languages for me. Applescript looks like a PITA.
Dmitri-do you accept payment to make custom firmware or some way to get this to work?
I'm not rich-I'm a working musician like everyone else here, but our live shows are screeching to a halt with such long delays between songs, and I've gotta figure something out. Feel free to email directly: joel (at) rattletree (dot) com
