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.
