Yamaha DTXpress/DTXplorer/DTXtreme

Hello,

I'm brand new to this group and to the DTXPRESS and I want to first 
say that I'm very happy to have found out about all of you fellow 
owners.

Having said that, I'm going to ask my first question. After assigning 
a misc. voice (m:), I experience a never ending tone. In other words, 
if i choose BRASS 4, the horns never stop they just hold that note 
forever. What do i have to do to have these tones play just one quick 
note each time I hit the pad?

Thanks,

Scott
