source code for both object look really diferent, so i don't know if it is possible.
but seriously : why do you need to replace vcf~ with bp~???

I wouldn't say I *need* to, I'd just like to... Here's an example: I was making a composition that used a choral pad with vcf~ objects acting as movable formants.  I decided I only really need the voices to sing "aaaaah," so I realized I don't need the movable formants after all, so I can economize on CPU by using static bandpass filters rather than moving ones.  I've never seen anything about differences between the filters' internal math, so I was surprised to find that they sound different.

So basically what I want to know is: if I have a vcf~ with a given q and constant center frequency, is there a way to replace it more cheaply?
