There's also quite a few EG+VCA combo modules that would be ideal for this purpose. Or perhaps using something simpler would do the trick, since we're talking percussion here and not something that requires a gate. You might consider Doepfer's A-142-4, which is a quad decay (Schmitt trigger, more or less) with a very fast fixed attack and ONLY decay as a parameter. Given that the rise on those is immediate, then all you'd be doing there is adjusting the "ring time". The A-142-4 can be dialed down to as short a decay as 20 msec or up to 2 seconds max. The factory setting on the attack time (3 msec) can also be adjusted via a trim pot on the board.
