Have you made use of the dynamics tool (transfrom). You can drag the midi track into the Transform players title bar (It's a bit of a secret, even XLNs tech guy didn't now). Then alter just the velocities of the high hats, or the accents of the sixteenths.
I'm partly asking, because i'm interested in how AD2 handles EZ drum map when you do this. BUt also because it's a cool feature of AD2, that's not knwon abaout. The one video I recently saw, had the demonstrator drop into a midi folder, but you can just drag it straight into the player's title bar.
