I never use the drum View, I am much more comfortable using PRV, which I wished would name the keys, so I could have the best of both words. I do use step sequencer though, and everytime I kick myself for not sorting out the drum map for AD2.
Just did it, it looks cool, very handy. Also deleted the 4,257,133 other drum maps I don't need to see. Just kept Session drummers in case I ever install it.
Being AD has been bundled for so long long, I don't know why it isn't part of the CCC install!?!
