Yamaha DTXpress/DTXplorer/DTXtreme

Hey guys,

this group is awesome,  I've read most of the posts, and solutions that you 
guys offer,  I just picked up a DTXPRESS last night from my local 
dealer,  It works great!!!  I just can't seem to get the HH Controller to 
do anything, no response at all, when I step on it I thought I would at 
least hear the sound of the two cymbals smacking together, and be able to 
do all those nice accents I like to do so much, but nothing!!!  not even 
open and closed,  its permanently open...how annoying....any answers,  I 
heard that it has an internal volume, inside the pedal itself is that 
true?  also how do I access all those midi voices I hear so much about, 
Guitar Piano Tuba, that stuff......Thanks for the group guys,

Herb
