[sdiy] OTA to voltage-control resonance?

[cheater cheater]

Hi guys,
I've been looking at some monosynths and one thing has me wondering:
if I have a potentiometer somewhere in the filter's resonance
feedback, can I safely replace it with an OTA based 'voltage
controlled resistor' without changing the sound?

I understand the best answer could be 'depends' - so, what does it depend on?

Do OTAs work like buffers, similarly to op-amps?

Thanks
D.
