MOTM

I think I misdescribed what I was going for, but maybe not... in this 
hypotehtical patch i made, the VCO was maintaining the same 
frequency... it was just that the resonant peak of the filter wasn't 
sliding up in frequency smoothly, it sounded like it was jumping from 
harmonic to harmonic (of the source tone)  Since there was just one 
note being sustained for 20 seconds, it doesn't seem like I'd need to 
patch into any frequency control on the VCF, though if I wanted to be 
able to play this sound...
arrgh getting incoherent here.  I think you probably *did* understand 
my question, and are just advising me on how to get the VCF to track 
the pitch of the VCO, which I can do (usually)

Anyway the sound I'm going for is a single pitched VCO with a VCF, 
and the sinewave type sound, the resonant sound that VCFs make at 
high resonance... the filter was being swept smoothly by the 
enveloper, but the resonant peak sound hopped.  I might just try to 
dig up a clip of it on my machine.  If I can manage to find something 
with that sound, I'll stick it on my site and post the URL.

Thanks for the help, though!
