Cheers matey - this really helps but there's still one more 
question..... (hee hee)

you wrote "If the timing and
the degree of interaction between switch and piezo are not perfect,
the desired rim sound won't take place."

Then how does a cymbal choke work? You can't hit the cymbal with a 
stick and choke it at the same time?

so surely the switch is working by itself there?
