Yamaha DTXpress/DTXplorer/DTXtreme

Just bought the Pinetech CC102ST pad at my local Guitar Center. 

Initially the snare wasn't very sensitive, but using 
the Voice Edit menu, I was able to tweak it to a more 
acceptable level. I noticed that there are already 
sensitivity presets that you can select. I started off 
with 'misc 1' and tweaked from there. I'm getting a bit 
of cross talk on the rim trigger, so I need to see how 
to correct that. 

I have been able to get both triggers to activate on the
Pinetech snare by putting a tom input into the rim input 
on the snare and the snare going into the snare input on 
the brain. However, I haven't spent the time yet to get 
the rim input configured on the DTXpress Snare input. Is this the
problem that you guys are discussing? Getting the rim 
trigger to activate in the Snare input on the DTXpress 
brain?

I wonder if the problem might be related to what I am
currently running into with trying to split the signal
off the '7crash' input on the brain. I noticed that only one
of the cable ends would allow a trigger to occur. It wasn't 
the cable because I could switch what was plugged into the 
splitter and I would get a trigger on the opposite end of the 
splitter cable. 

Then I noticed that if I hit the crash, and then immediately
hit the other pad in '7 crash', the sound would stop immediately.
So, I knew that the pad was doing something, but I couldn't get
it to trigger so that I could assign a voice to it.

So, investigating the DTXpresss manual, I've found that I can get
the pad to register on the brain if I 'enable' the Rim to Pad 
setting (on page 45 of the manual). Now when I hit the pad, I 
see that the pad is registering on the brain, but the next 
difficulty is getting a voice to activate after each pad hit. 

I'm still not sure if this is what needs to be enabled for the
pad to start to produce voices, or whether I have missed a step
somewhere else. Anyone have any experience with this part. I'm 
curious if this could be the same problem that is happening with
the snare?

Sorry for the long post, but now that I'm deep into this drum set, 
the questions are really starting to pop up.
