By the way, there is actually a fofilter opcode in Csound 5,
but the Fofilter UDO is probably useful as it can run on
Csound4.

I don't know the nord modular filter, but I suppose in
order to make a vowel filter, you can group four or
five fofilters, with the right formant CFS, attenuation
and bandwith.
