Hi Rich
First off, let me tell you I'm no expert. But the D-beam isn't likely to be able to do the things you wwant. I have an EM2000 and don't use the D-beam at all. Mostly because it is blocked by a Yamaha keyboard that sits on the top tier of that stand.
From what I remember, Roland has a menu page of a limited number of functions you can choose for the beam. I don't think you can choose which CC message you want it to effect. It's an interesting device - just not all that useful. Others may know more.
