Cgs synth

So,
has anyone got one of these VCO's up and running yet? I am really
curious to hear the what people think about the waveshaper, sub osc
features, and overall sound. I am working on making one up for my
system, but I can't decide if I want to add the kitchen sink or just
keep as a more basic vco... any thoughts would be helpful.
one final thought, there is no pot for Pulse Width on the
schematic, could that be added?

thanks

Howard
