outlets for the real and imaginary value. These may be used as bandpass
and lowpass filter outputs \, or combined to allow other possibilities.

#X text 42 54 Vcf~ is a resonant band-pass and low-pass filter that
takes either a control or 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 but more powerful than
the bp~ bandpass filter., f 63;
