Yamaha DTXpress/DTXplorer/DTXtreme

Steve,

I'm on the road, but I wanted to make one thing clear. Rejection 
proper is also a local phenomenon on the dtx. In principle, it, like 
specific rejection, won't work on crosstalk emanating from pads 
connected to another interface either. But the longshot is that when 
you hit the tom on the PM-16, you may also be hitting something on 
the dtx, like the kick--at least some of the time--that will activate 
rejection and protect the cymbal. Like I said, it's a longshot. In 
general, the PM-16 and the dtx have to take care of their own.
