I am not sure if it is what you are looking for, but in the files
section there is a circuit called "DTXpander cheap" which will allow
you to convert two piezo signals into a piezo plus rim switch signal.
 If you are building your own snare, you might want to look at the
DIY-edrums Yahoo group as well

Also, the edrum for free web site might be of interest
