Also crucially, the similated rim switch close timing and duration 
seems to be important. If you just hold the switch closed, and hit 
the pad, you only get the main pad sound. The MRD (say, that has a 
nice ring to it) needs to take that into account.

If this worked (big if: I'm a plumber, Jim, not an electrician), you 
could build a small box with two banks of four mono inputs and four 
stereo outputs. Using the kick and tom1-tom3 inputs, you'd spring 
four more pads on a DTXPU.
