I haven't built a CGS 75 yet. I am waiting to see what the Bridechamber
MOTM format panel looks like first. And I'm waiting for the CGS-75 PCB
boards to become available from Ken Stone again. But I can give some
answers.
The AC output is ground-centered - it has zero bias.
The Rise/Fall CV pots are reversible attenuators, with the center
position being the minimal amount.
Exponential CV affects both rise and fall equally in an exponential
manner. If cycling, it works similar to a 1V/oct CV input on a VCO, but
not accurate to 1V/oct.
I designed a Front Panel Express panel for the CGS 75 Serge VCS. It's
available in this directory on Yahoo Groups:

On my panel design I put input and output jacks for the Processor, so
that it can be patched in wherever you want it. I think the best option
for hard-wiring it would be in front of the Both CV input.
