+#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.
