Yamaha DTXpress/DTXplorer/DTXtreme

Hey guys

I decided to take the DTXpress to live gig this Friday, if anyone is from 
long island its at Shaker27
on sunrise Highway, anyway.  I need help. I got everything to sound pretty 
good, except  for the hi hat. it sounds very electronic, like some R and B 
salt and peppa hi hat.  Anyone got any tips on how to tweak it up to sound 
good, other wise I'm just going to use a real hi hat

Thanks
