Yamaha DTXpress/DTXplorer/DTXtreme

Greetings one and all,

I am hopefully about to embark upon the fun and frustration of 
owning a DTXpressII. I have a couple of questions on the thorny old 
topics of dual and triple-zone pads... but hopefully questions that 
are not too dumb. I have searched the archives, but this group 
almost uniquely suffers from a problem of too much signal to 
noise... there's a lot of good stuff out there.

Triple zone... am I right in thinking that this is either one piezo 
and two switches, OR a very clever way of processing one piezo and 
one switch to get two different effects when used in combination?

Either way, while I can see that being useful for the snare (for rim 
shot and cross-stick) I struggle to see how that setup is especially 
useful for the other pads it's available on (6 and 7, ride and 
crash). Stereo I can grasp (bow and rim sounds and/or choke) but 
what use is another switch? It can't be used for a bell sound, can 
it? Can someone give me a scenario where the triple-zone 6 and 7 
input can be used to good effect?

Lastly, can someone confirm that since the hi-hat trigger is stereo, 
I could replace the TP65 with a dual-trigger cymbal pad and get a 
more useful bow/rim setup for the hi-hat?

Hoping to join you more in fact than spirit soon...
