Yamaha DTXpress/DTXplorer/DTXtreme

Hi Everybody,

I have just bought one of the DTXPress III Special Electronic drum
kits. The set is very good in general however, I am experiencing a
problem with the hi-hat. My problem is, to have the footCIV sound I
need to close the hi-hat too fast. And if I close it slowly it just
doesn't recognise the move. Any help and suggestions will be
appreciated...
