Hi Ross

> ok, now you got me thinking...if you take the inverted out of an envelope, run it thru a linear mixer, and add a voltage bias from the S&H as i describe, would it achieve the "zero crossing" Stu describes can't test atm...

Yes this would work as you think.

Thats what I am doing always.

Btw. some years ago I played around whith dc-coupled Audiomoduls. It can
have really nice effects. But the disadvantige is, that you always have
annoying clicks or "whoooom"s if you switch to some module or add its
signal with the mixer, which is not bearable for live situations. Thats
why I decided to go back to ac-coupling.
