If you look through the archives of this mailing list, or (more simply) look
at the comments by John Loffink at the end of the page on Ken's CGS site
about this filter, you'll see that some people have found that the frequency
control has too much effect rather than too little. That suggests to me that
something is wrong with your filter.
I started with John's modifications but ended up adding a new op-amp-based
CV mixer to get this filter to work to my liking.

Subject: [cgs_synth] steiner filter supercharger?
Well, my first attempt a +/-15 device - a Steiner filter - isn't going
so well. Seems the frequency and res controls have little or no
effect, depending on which input is being used. I will keep tweaking,
however. I'm quite new to this, although I've built a number of
successful 9V devices.
