Yes, it is. However, the rim membrane switch is actually divided 
into two. The track runs from the PCB (where the cable plugs in) out 
to the point where the 'S' is printed on the rim, then divides - 
half runs clockwise, half anticlockwise. One half can (and does) go 
bad. I have a PCY80S cymbal that only has a working rim trigger on 
one side. Not much you can do about this, I'm afraid.

Cross-talk. The vibration is being machanically transmitted down the 
cymbal boom, into the rack, and then to tom1 where it's enough to 
trigger it.

First, make sure the wing nut isn't done up tight on the cymbal - 
there should be some play. Then look at the "specific rejection" 
parameters (trigger settings). The tom1 trigger should be set to 
reject the cymbal trigger (whatever the input numbers are). Try 
raising the value.
