Possibly the best VSTi for natural sounding drums out there.

Take your MIDI file of the arranger drums, map to this, edit the part so ALL the fills are a bit different, and stand back in amazement! Close mikes, overheads, room mikes and distant room mikes, most drums have at least 15 or 20+ velocity levels (snare MUCH more than this), top and bottom mikes for the snare, in and out mikes for the kick....

I could go on and on

Only problem is that ALL the drums are recorded without ANY EQ or dynamics processing. You get basically what you would get miking up a live drummer. It's up to you and your plug-ins to get that 'studio' sound, but at least YOU get to chose how to process them, not someone else!

I can't recommend this too highly, especially for your rock-ish flavor. It's still only as good as the MIDI file you play into it, but feed it a good one, with nice dynamics, and it can fool even the pickiest of ears...
