If I play with velocity wouldn't that change the sound of each drum? I mean it wouldn't just make it louder, but it might trigger a totally different sound that resides on the same drum key note...

Since you mentioned EQ, tell me what's your favorite EQ setting for the "parts" in the Master Equalizer setting. I use "Jazz" since the piano sound on the left side sounds low.

Or what's your setting if you tweaked things yourself? (I would need the exact numbers "parameters" for the High, Mid, Low that you use, so I can set it up on my BK-9 and hear your setting)
