OK, is there a reason that dual zone and triple zone pads are 
stereo?  Do they have to be stereo?  Can you have a dual zone mono 
pad?  Example:a dual zone ride, with the pad and rim of cymbal 
having to seperate voices, connected to mono?  Thanks.  I swear this 
confusion is throwing me off beat!

Unfortunately, we're stuck with the use of the misleading 
term "stereo," rather than "dual-zone," to describe pads that 
comprise a piezo main trigger and a membrane switch (for choking 
and/or rim sounds). The reason is that the description "dual-zone" 
is reserved for pads and cymbals with two independent sounds, either 
from two piezos or two FSRs. These pads--like the Pintech 
ConcertCast snare with its independent rim and body piezo triggers, 
the Hart ECII ride cymbal with its bow and bell piezo triggers, or 
the Drum Tech Pole Pad with its dual FSRs--must use two inputs on 
the DTXPIIU, either 9/10 or any combination of two inputs from 1 to 
8. A dual-zone pad is essentially two mono sounds, each of which 
requires its own input (although there are modules out there that 
will allow such double monos to plug into a single input with a 
stereo cable--adding to the confusion). The distinctions only become 
clearer when the abstractions are associated with the actual pads 
that they represent, because you could never understand what a 
stereo pad is simply by the standard definition. In point of fact, 
the stereo in e-drum lingo has absolutely nothing to do with the 
stereo that we all know from audio.

Thats exactly what I was looking for Ed because I think I saw you 
discuss that at some other time but I didn't print it out.  What are 
piezos and FSRs exactly?  They're the same thing though right?

Piezo's and FSR's are not the same.  FSR stands for Force Sensitive 
Resistor which operates pretty much as described in its name.  Piezo 
crystals actually generate a small amount of voltage in response to 
pressure that is applied to them.  If you have a pad that has both a 
piezo in the center and an FSR strip around the rim, then you 
definitely need a stereo cable to convey these two signals back to 
the drum module.

Hope this helps,

Ed
