bp~ doesn't work properly if you try to set its center frequency above 1/4 of the Nyquist frequency, e.g. above 11250 Hz in the case of 44.1kHz sampling frequency.

If you push the center frequency above that value, instead of raising it, it seems that the center frequency and Q don't change while the GAIN of the filter grows.

Note that vcf~ does _not_ suffer from this problem.

    I'm trying to raise the priority but I get an "update failed" error

    Ok I guess you just can't change the priority and post a comment at the same time? (a bug in the bug tracker?)

    Well I think this deserves higher priority because it is one of the most basic objects not functioning as expected.
