Yeah thats what i do too. When you do you dont have to know what the cc numbers are!!! And you get more feeling to your tweaking.

Well wadda ya know, i was reading an article and it seems there is a virus c midi device panel included in cubase sx 3 , works like a charm :D :D
Just go to the midi device manager , click import setup , go to the steinberg\cubase sx\midi device ... and there it is , isn't that great.
After trying all the CC's and stuff i find out there is a midi panel included haha.
