+#X text 15 429 Frequency and pitch are converted using the "ftom" and
+"mtof" objects. Frequency refers to the number of cycles per second.

+\, and so on.;

+floating-point messages to set its frequency. Without arguments \,
+its frequency is controlled by connecting an audio signal to its input.
+;
+#X text 14 496 Mtof and ftom work fine for microtones (non-integral
+"MIDI pitch" ) and don't have MIDI's range restriction-- for example
+\, MIDI -36 is about 1 Hz.;
+#X text 15 553 Note also the "set" messages going to the number boxes
+so that they can each update the other without bringing on an infinite
+loop. (get help on number boxes for details.);
