Well, now I'm successfully getting CC messages from the BlueBoard to control things on the H9. A welcome step in the right direction. 

I'm just randomly assigning controllers and testing things for now. I'm getting some unexpected behavior. For example, I have the "A" button on the BlueBoard set to send CC20. I've tried assigning it to toggle between Active & Bypass on the H9 (something I wouldn't do in reality), as well as toggling the tuner. In both cases I have to hit the A button twice to activate, and twice again to bypass. Obviously, I'm expecting it to toggle between the two states with a single hit of the A button, instead of two. 

Seems like a probable BlueBoard problem. Any suggestions on this? Thanks.
