DIY drumpad/controllers

:::Martin,Paul,& DIY,

:::will perform the function of holding a peak voltage

My intention was to use the spike (it is more like a "ring") for
triggering a cheesy drum box resonator.  Thus the amplitude will translate
into resonance wave amplitude.

Anyway, holding means a s&h  or a peak detector?  I guess a peak
detector. Then the only question is how will it be reset for the next hit?
