Yamaha DTXpress/DTXplorer/DTXtreme

Okay, got ya. Here's what I think is going on. Input 9/10 will 
handle two mono FSRs or two piezos but not one piezo and one 
membrane switch from a "stereo" pad or cymbal, because stereo pads 
and inputs have a totally different electronic makeup than their 
dual-zone, or mono, counterparts. Inputs 1-8, as combinations of 1 
piezo/2 membrane switches (or FSRs), would seem, in principle, to 
permit a triggering opportunity for the two independent FSRs of a BP 
80 or its equivalent if you could just get to them. The problem is 
that those two membrane switches are not independent triggers. Their 
open and closed positions (membranes are basically open/close 
toggles) determine what sound the piezo is going to make--whether 
the sound programed to the rim, the body, or a choke; the switches 
are, if you will, slaves to the piezo. The timing of how the 
interaction between them takes place, not to mention the delicacy of 
their relative physical locations in the pad, is complicated. But 
the upshot is that creative cabling won't help you; those inputs are 
by nature single piezo inputs. You can't treat the "stereo" 
or "trio" inputs as taking multiple mono feeds, whether piezos or 
FSRs. Anyway, that's my understanding.
