hello bakis,

maybe dieter should also purchase an
analogue solutions sy02 filter for comparison
and take a look at their efforts. they did
really well with the sy02, but dieter can sure
make some improvements like vc of resonance and
the rest of those nasty things you already
mentioned below.

there is another filter i would appreciate, because
it is totally unavailable. i'm speaking of the vintage
yamaha multimode filters. they are a bit weak, but
very creamy and soft. the sound is significantly
different compared with the cem3320 based filters.
the yamaha is (like the korg) made with custom chips.
the slope is 12db for highpass and lowpass and
6db for the bandpass. a long time ago i owned an
yamaha cs20m and i can still remember those creamy
sweeps. but i sold the cm20m because the rest was crap.

best wishes

self oscillate
