I see your point, but--
Don't you already have voltage control over frequency on your 420s?! You
should have three inputs that will control the cutoff frequency via voltage,
labeled: 1V/OCT, FM1, and FM2. What you ∗don't∗ have is voltage control over
resonance amount. You do get that (as well as cutoff control) on the 440.
I don't know the technical answer to your question, but having asked similar
questions on AH awhile back and getting learned responses from the likes of
Kevin Lightner and probably Paul too, the answer is no. With some circuits
it might be a simple matter, with others, not a simple matter. So there
would be no "generic" approach that would work.
