[sdiy] Famous Fixed Filters - FFF PCB ?

[Jorn Bilse]

I agree, although it would probably be a box with a different design brief than 
Famous Filters. I would definately buy a filter box with the design brief of 
simply trying to be the BEST sounding analog preset formant filter ever made, 
one which can turn any string machine into a choir with an extended set of 
preset formants like "Ih", "Eh", "Ah", "Oh", "Uh", "Mm", that could quickly be 
called up at the touch of a dial and where adjacent formants could be crossfaded 
with an envelope or LFO.

As has been noted in recent posts today, in order to achieve this, some time 
would probably have to be spent analysing the frequency spectrum of the best 
sounding vocal formants and applying those spectra to the circuit design to get 
the closest approximation and thus the best sound. This is where creative 
circuit design would be important in order to make an efficient design with as 
few filter poles as possible, but which still matches the measured frequency 
spectrum pretty closely, and the artistry would of course be in determining what 
the best formants are.

i've been trying to get good formant type behaviour out of my modular
for ages and so far i've not been that happy with the results.

i would buy a PCB just for the VP330 filter! anything else would be a bonus.

thanks for providing excellent designs to the community.
