[sdiy] good VCA chip?

[synth at charlielamm.com]

I built a VCA using the 2018T....copied the exact circuit
in the spec sheet, just added an inverter and voltage summer using
a TLO72 to process the CV before hitting the VCA's control input.

To my ears, the VCA sounds good, and was certainly easy to build.

However, I have not tried running DC-CV through it.  Only audio.  Someone
else in the group probably has first hand experience with using it to
control DC, if it's even possible.
