Ok, it sounds like what I suspected is true.. There is more than just an on message sent for each CC.. Or rather a single message with more data than I originally suspected. So I understand now when I "unclick" or turn off the IA button on the voodoo it sends a CC05 plus a zero value (sticking with 05 to be consistent). What I still don't see is how to tell the voodoo what value to send when the IA button is switched to on. It seems like I need to tell it the button is CC05 and a value.. I don't see anywhere that let's me choose a value. I guess I better try voodoo support
