You are right - it is the tip of the jack plug which connects to the
piezo.  The ring is connected to the FSR.  When you hit the rim of the
pad the FSR shorts the ring to ground.  In the case of a three zone
pad, the extra zone is created by using a 10k resistor in series with
the FSR.  By the way, if you try shorting out the ring and then
hitting as pad it won't work.  The DTXpress box expects the switch to
be closed just before the piezo signal arrives.  Try holding the rim
of you snare and hitting the pad and see what happens.

If you look in the photo section, someone (OGD I think) has kindly
dismantled and photographed just about all the Yamaha kit.

I think there were discussions about FSRs on the group a while back,
including where to buy them, so if you search the message archive you
should find it.
