[sdiy] [AH] Interested in Trapezoid VCA PCB?

[cheater cheater]

So what functions does it have currently? I'm not that familiar with
the Synthi :)

My memory says it's a looping envelope + vca, but is that so?

Where does the "coloration" that you mention come from in the vca -
does it use some special topology?

Cheers,
D.
