nice solution. i say that a little sheepishly, since i do just that
with the snare sound, but am apparently too dense to apply the same
idea to a hihat :{

i met two disadvantages doing this. the first was that the trigger
delay that i use to stretch the trigger covers the entire usable
drum-typical range over about five degrees of a pot turn. dieter, if
you're listening, is there a simple hack to reduce the entire trigger
length range to, say, 1500ms

the second problem applies to all adsr-based solutions, namely no
dynamic variation. so i'm using a few selfmade slew limiters, which
give great results, but i've yet to think of a rack-space friendly way
to kill
the release. i suppose a vcs used to short the cv to ground would do it.

or the fricke hihat module, but that's cheating :)
