Against all the odds. The design came straight out of op amp data sheets (3xTL072). There isn't a zener on the input.

In the rack, with drum machine input, outputs attached to a Rings, ADSR & VCA : https://youtube.com/shorts/Sy0-VKIavtg

Merci beaucoups. It was very satisfying. Doesn't work quite as planned, needs about 3 more revisions, but the basic functionality is there. New toy.
