MOTM

It's an envelope generator (which can be used to modulate anything, filters etc.) *plus* a (very special) FET-based VCA.

I'm confused. Doesn't trapezoid refer to the shape produced by the envelope generator? What is a Trapezoid VCA?

Thanks,

I wonder how many interest there would be in a PCB for a Trapezoid VCA.

It would - of course - be designed to emulate the behaviour of the famous EMS Synthi A and VCS3 Trapezoid, and it would be - of course - not be a direct copy of the EMS circuit.

Usual pricing for my PCBs, no exotic components needed, rather easy to build, no component selection necessary.

Let me know.
