it's how the filters were designed, they're not

Probably it would be better then to warn users about this limit of
~12 kHz in the help-files then.
you'll need to use/build other filters for that
purpose of working with that higher portion of the spectrum (in
which I can hardly still hear, by the way)/
Hmm, I can clearly hear the difference between feeding a high
frequency to [vcf~] and to [bp~] using a large enough Q (~100 for
instance). With that Q, try sweeping from 12kHz until 14kHz in both
filters, and you'll hear that [vcf~] behaves as expected, while
[bp~] does not change the frequency but only affects the amplitude
of the output for some reason.
a few of patches of mine that describe the behaviour
of vanilla and some extended filters
Thanks a lot for the patches, but I am actually aware of [vcf~] and
[biquad~]. This message of mine was intended to be a bug report
rather than a cry for help as I have no particular problem with
filters needing a solution right now. But in any case I will check
your patches, as I know (and enjoy very much) yours Computer

Take care,
