Anyway I think Fonik's SSM2044 is a good and useable filter. Only the resonance control needs to be adjusted slightly to get it easier into selfoscillation.

use trimmer T3... this trimmer is not on the first schematic i released.
current release: http://modular.fonik.de/files/SSM2044.pdf

Hey Fonik btw, could you sell me a couple of those SSM2044 boards without the SSM chips?

PM me and we can talk about...

there are still two sets of PCB+SSM2044 IC available.

Just an update
I've got the ssm2044 VCF up and running and it is sweet

if you drive the resonance hard it has a harsher edge

I've only managed to get it to track 3 octaves with the cv but I haven't spent that much time getting it in tune as i've had more fun playing with it

cheers Matthias for another fine PCB

I will try and sort some samples out soon when i've got it tuned a bit better
