Yamaha DTXpress/DTXplorer/DTXtreme

Sounds really cool, was wondering if it would work with previous 
versions of the dtxpress module? I have a dtxpress2, and expanding 
the kit is always on my mind this sounds like the thing to do it! 
Also, just a suggestion, if you could work it out to bring the price 
down to 100, 150 us, i bet you would sell a ton, at the current 
estimated rate, it would be easier to buy a second module, in the 
u.s. or canada. I would pitch (then sell $$$)  the idea to yamaha, 
they might love it and  may add it as an accessorie for the dtx 
line.......Good luck!             KEEP ON JAMMIN'! ........JAYMZ.
