flies

so i'm interested in getting traditional subtractive synthesis sounds out of

max, and i've got a whole CV scheme biult with virtual 'modules' and such.

I'd like to make some filters that sound a little better/more interesting

than the stock svf, biquad, etc. I looked into the mcgill nord modular

online book, and they suggested that 'dispersion' was one thing that would

I've tried doing some crossovers and doing my dispersion that way, but what

i'd like to try is to get some kind of dsp object that had a very non-linear

phase response but a fairly linear amplitude response, and put that inside

an explicit feedback path to the svf~ doing the actual filering.

Any info on making dispersion and/or improving the stock filters?

the desired finished product here would be an filter abstraction that would

respond to frequency and Q input, and maybe some third 'analog feel'

There was just recently a long thread about the same issue...

look for the ms20 filter thread in this forum. there's a cool patch made from standard msp objects to get that "porn" feel... (i presume that's what stefan had in mind - the patch not the porn! ;))

however that's not using dispersion techniques to get that wet nord filter sound. allpass~ or some sort of random short delays in the feedback stage might get you closer... perhaps u can look at some of the diffusion techniques used in reverbs to get some ideas.

theres lots of ideas in the article you posted. try connecting up biquads in various configurations. use distortion between them, try feedback, try using staggered cutoff frequencies, vary the resonance with the cutoff, vary distortion with the cutoff. each low pass biquad is a 12db (2 pole) filter. so two in series gives you 24db (4 pole) . 

the frequency dispersion moistness sounds dubious to me, but try that too! then write back and tell us what sounds good

Wooh! Thread link! WOOT PORN FILTER :D yeah I love that sexy bass analogue filter feeling mmmmmmmmmm

Id love to see what you come up with for the nord. I loved the filters on that. I also was really into their FM sound, I was planning on trying that out soon too.
