Hi Ingo and joost
> i don't know what it is that makes sallen&key filters so special,
As far as I know, the S&K-filter is based on one OpAmp with two rc-pairs
(one in the feedback line, one in the comparator line) instead of the
one rc-pair with other.
btw: a friend of mine owns a 800DV, so I know it a littlebit. I have to
admit, that the filter itself sounds not that special (I wouldn't stand
in for a dedicated module because of the sound), but the access to the
combined cutoff is very cute.
