Hi,
If you set the Delay and Level to zero does the ring mod change ?
Btw, I'm in London, where are you based ?

On this machine, it was far enough gone that I had to replace both IC30 and IC31, and do a fair amount of point-to-point wiring underneath. That said, I'm still seeing some misbehavior.

As best I can figure, it's the filter, not the VCA, that's being modulated at high frequency, as playing with filter cutoff/key amt/env amt changes the amount of this modulation. It's definitely not the LFO bleeding through anywhere - LFO speed has no effect on this audio-rate mod I'm hearing.

I understand just enough to have gotten that far, but am not sure where to take it from here.
