You really must look back through the group archives - this has been 
discussed in detail many times.

The switch triggers no sound on its own. It modifies the sound 
triggered by the piezo. Piezo with switch open gives one sound (the 
centre of a cymbal, for example), piezo with switch closed (the edge 
of a cymbal) another. For choking, the piezo is not triggered at the 
same time but the module interprets the switch close (for a suitable 
pad type) as an instruction to mute the sound being played. 
Yamaha's "3-zone" inputs are the same, except they have two switches 
and (we assume) the switch transition for one is distinguishable 
from the other; perhaps one goes positive and one negative. There's 
still only one trigger.

The Yamaha inputs are not dual trigger. That description is used for 
pads that have two piezos. They are stereo - a stupid name used to 
distinguish them as having one trigger and one switch.

The stereo inputs CAN be used for separate sounds, they just can't 
be split onto distinct pads (until I figure out how to make my magic 
box).
