Yamaha DTXpress/DTXplorer/DTXtreme

I am STILL having a terrible time programing this midi kiti.  Seems 
like EVERY input is on Channel 1, I"ve changed them to 10, and MOVED 
my Visulite FROM input 1 to 4, and I STILL can't get a sound out of 
the cymbal when I hit it.  Funny thing-GATE time is set to 0, and I 
can't get it to change no matter what...is this supposed to be that 
way?  I am ready to send this thing to Alt. Mode and have them check 
it.  Lord only knows what it was set to before I bought it...can 
anyone offer me any suggestions?
