Well, now I'm confused. Your last post said, "Sustains with that level at
zero then turns off w/out it moving." Could you rephrase that? Are you
playing a scratch sound, or something with a non-infinite decay time on the
volume envelope, or something with some nonzero release time on the volume
envelope? What is the voltage doing, and what is the sound doing?

Well, Clean is Good, but so far I don't think you've got a S&H problem.
