Yamaha DTXpress/DTXplorer/DTXtreme

First off, Very nice work! If it were me, I'd a little bit of 
research and tweaking, if any, and see about patent ideas? I'd wait 
to disclose any info till you have the idea secured. Anyways, good 
luck, and I agree with the 4 to 8 box idea. And I would buy one or 
two cause I think I'm gonna get a second module as well =). Oh the 
endless possibilities!
