Mackie MCU Pro as CC controller, anyone?

Well,

I’ve tried to make it work. In fact, using the logic Editor as insert, It works fine. But only for one track. If I set one midi track for modulation, and other for let’s say Expression, the pitchbend message is send to both, regardless of what slide I am moving on the Mackie Pro.

Anyone with a hack solution?
Cheers
