#X text 168 499 - the filtered signal (imaginary part).;
#X text 76 283 [vcf~] is like [bp~] except that it takes an audio signal
to set center frequency \, which may thus change continuously in time.
The "Q" or filter sharpness is still only set by messages. More expensive
than bp~ in CPU time but more powerful too.;
