Yamaha DTXpress/DTXplorer/DTXtreme

Greetings All,

I posted this question to the Roland Handsonic group and didn't get a 
response.  With all the knowledge in this group, I'm betting I can get 
an answer.  And no, that isn't just blatant sucking up.

I'm thinking of buying an Roland HPD-15 (basically an electronic hand 
drum) and hoping I can use the foot controls and triggers from my 
Yamaha DTXPress II.  It can support the Roland High Hat Controller and 
Kick Drum Triggers.

Has anyone gotten the Yamaha HH65 Hi-Hat Controller or the HP65 Bass
Drum Trigger to work with the HPD-15?

From my understanding, the HPD-15 is electronically similar to the V-
Drum module.  Of course with pads designed for hand drumming. 

Thanks in advance.
