Also, do you think there is any way this circuit to could overall voltage-controlled gain (like the Serge X-fader)? Maybe more CV summing tricks? Or another VCA needed? Hmmm....


Two VCAs? You mean one to do +X-Y and another, with its own CV and initial pots to control the level of +X-Y to the two output amps? Too many pots for my taste, but yeah, I suppose it would work. Might even allow, via switches, for the 2 VCAs to optionally function independently.

Depends on how you wire it. Serge systems always seem to have more features on the boards than are always brought to the panel. For example, the difference between the Universal Slope Generator and the different transient generators, clocks and oscillators built from the same circuit.

But this doesn't look like too many pots to me Cool

bumping this old thread - these circuits look great! Any further developments or testing done by anyone yet?

I'm thinking about trying the 13700 version...
