Yamaha DTXpress/DTXplorer/DTXtreme

Woooohoooooo. I got to open up my DTXPRESSII last night and jam on it
for the first time!!! Oh man it was exactly what I had expected. We
recorded the whole session, so I shall be posting it soon. It sounds
fantastic, and so easy to play. We were super impressed by how well it
records. Recording directly into the MiniDisc was a dream. Every
subtle nuance from some of the wackier kits got recorded perfectly.
Now comes the long and complicated task of tweaking those kits so they
sound a little bit more realistic. Any advice for setting up for the
first time? Which one of the pre-set kits do you use most often? Which
one is the best to sculpt into a realistic drum set?

DTXPRESS ruuuuuules!  ;)
