	I'm working on a drum pad interface and I thought this sub heading
might prove more definitive of the project on this group.
	What I need is a circuit that will take voltage from a piezo element
and 1) Close a contact immediately 2) Close another contact after a delay
period related to the voltage of the trigger signal.  This delay will be
very small, I'm sorry I can't give the range in microseconds, it's less
than one second.

	Anyone have any ideas?

	It must be a *very* responsive circuit.


				Thanks...
