Pete,

Stereo pads and dual-zone pads are two different animals. The TP80S 
and PCY80S are indeed stereo pads. They have a main piezo in the body 
and an FSR on the rim. The FSR is completely dependent on the piezo, 
parasitically toggling a different voice through it when struck; it 
is incapable of sounding a voice by itself in a stereo pad. Stereo 
pads, which are typically gum rubber, only offer two voices when 
connected through a dedicated stereo input like those found on Yamaha 
and Roland brains. They will not split into two mono inputs such as 
9/10 on the dtxpress brain or any two on the Alesis to give you two 
voices.

Right. Stereo and mono pads behave in exactly the same way when 
connected to Alesis modules because these modules don't have inputs 
capable of detecting the FSR on the rim of stereo pads. Read on.

Here's where the distinction between dual zone and stereo applies. 
Those dedicated stereo inputs that I just described cannot pick up 
dual-zone pads because dual-zone pads are essentially dual-mono pads, 
meaning that they derive their separate voices from two piezos that 
act independently of one another. They need two mono inputs to work 
on the Alesis Pro. Inputs 9/10 on the Xpress are tailor-made for 
them, though the Xpress will also allow you to program their separate 
voices through two stereo inputs if you don't need them for stereo 
pads. The Hart Pro snare, the Hart Ecymbal II ride, the Visu-lite 
dual-zone ride, the Pintech AX14S are all dual zones that require two 
mono, or stereo, inputs to work. Obviously, if you have stereo pads 
from the Xpress that you want to use, you won't want to take up your 
stereo inputs with dual-zone pads.

Got it?
