Hi,
By playing around with bp~ I've realised that the center frequency can't be raised above 1/4 of the Nyquist frequency (unless it is some "magic number" about 11000). If you raise the center frequency above that, it seems that the actual center frequency sticks to that value and the gain of the filter grows.
Is there some "natural" reason for that??
thanks m.
Well I have just tried vcf~ and it does _not_ suffer from the same problem, so I begin to suspect that the answer to my question is probably "no, it's just a bug"...

And sorry, I meant 1/4 of the sampling frequency, that is 1/2 the Nyquist frequency
