#X text 18 23 The more "natural" units for describing a formant might
be center frequency and bandwidth \, so that you can change the fundamental
without having the formant shift up and down in parallel. Here all
three frequencies are expressed in MIDI units. The bandwidth and center
frequency have to be divided by the fundamental (the expr 1/$f1 takes
its reciprocal and two *~ objects finish the division.);

#X text 19 137 Here we take a somewhat lax approach to sampholding
the center frequency control. The frequency itself changes instantly
\, but the center/fundamental frequency ratio waits for the next period.
This gives a slight "chirp" if the fundamental is abruptly raised a
couple of octaves. There's no easy way using Pd's built-in primitives
to avoid this. Note however that there's a "paf~" extern available
which solves this problem better and \, moreover \, runs much faster.
