Yamaha DTXpress/DTXplorer/DTXtreme

Hi you guys,

I got me a dtxpress 2 a couple of months ago and I'm very happy with it.
The only thing that sucks are the built-in hi-hat sounds. Can anybody
give me some tips on how to adjust the hi-hat sounds to a good rock
sound. The hi-hat pedal could use some adjustment too. I can't get it
to act "natural" maybe someone could help me there. Please post some
syx files, I'd like to know how other people's kit sounds.

regards,
Tom
