Yamaha DTXpress/DTXplorer/DTXtreme

Sorry to have waited so long to get back... been very busy!  Anyways, 
thanks for the input guys; I was able to fix the problem, but to this 
day have no idea what it was.  The volume was up, it would trigger 
the sound with the pad, just not MIDI info.  With MIDI you could hear 
an almost imperceptible click and that was all.  God knows waht I did 
to it to make that happen, I don't.  But when I reset it to factory 
default it worked fine, I was just hoping to not have to do that!  
Anyways, thanks for the help.
