"Stereo" is really a misnomer for inputs 1-8. What the term 
designates in e-drum parlance is an input that handles a pad or 
cymbal with a piezo trigger for the body and a switch for the rim.  
The switch section of the input cannot be swapped out to an 
independent pad; it must belong to a single pad that has a piezo 
trigger as well. In other words, "stereo" in this context does not 
translate into a left/right situation. Think of "stereo" pads as 
mono rubber pads with an attitude, not as dual-zone pads with two 
separately triggered bodies. Dual-zone pads, with two piezos, 
require two distinct mono inputs, or two distinct "stereo" ones (the 
rim switch doesn't count as a fully independent mono trigger), or 
inputs 9/10 via a splitter. Only one of their voices will sound on a 
stereo input with a stereo cable or with a splitter. If you want to 
build a killer kit with 16 pads (or, more precisely, 16 piezos or 
FSR triggers), you'll need either another module and a mixer or some 
sort of midi interface that can go through your module (like 
Roland's current TMC-6, former PM-16, or Kat's old midiKITI, but 
that's another kettle of fish. Aren't you glad you asked?
