Yamaha DTXpress/DTXplorer/DTXtreme

First, an aside.  I have recently resumed drumming after a 34 year 
hiatus.  There is a definite theme developing here.  Unwittingly, I 
have joined a group that has at least one  thread other than Yamaha 
DTX running through it.  Advanced years would be it.  

I think that thread goes to the often posed questioned concerning 
the issues that distinguish accoustic and electronic drums. I don't 
know if others have already confronted this but how about the weight 
of acoustic equipment compared with the weight of electronic kits.  
The difference really matters to me.  I cannot worry much about the 
the realism, the relative dynamics etc. of a kit that I cannot 
carry.  I wonder if the American Medical Association has statistics 
on the relative likelihood of having a coronary if you play (and 
carry around) e-drums or acoustic drums.  But I digress ...  

I have recently added a PCY65s and a TP65 to the standard DTXpressII 
kit.  I linked the PCY65 trigger from the base kit along with the 
new TP65 trigger to input 9/10 using the 2 monos to 1 stereo 
adapter.  I programmed the two inputs as a ride cymbal and as a Tom 
4 in this instance, respectively.  Both triggers send out the same 
voice even though I programmed 2 different voices.  The rest of the 
kit is working as programmed.

Perhaps, just perhaps, I have erred in some way.  Anybody have some 
light to shed?
