Looks like Roger has his tracking quite nicely. I have never had the
opportunity to play with the dot com filter.  But, I sure do like this one.

Very interesting.  Thanks for the detailed info, as I have been
curious.

I just stuck a frequency counter on my Synthesizers.com Q150 ladder
LPF after reading your reply.  The results were:

220
440
882
1755
3456

Like your filter, this one can be tweaked (though not internally) for
greater accuracy in particular ranges.  It does have a nice sweet
sine.  Interesting to compare.
