+#X text 172 419 to listen to.;
+#X text 97 511 You can make a phasor-generated envelope generator using
+"min" and "clip" to combine line segments. Here a rise segment starts
+at phase 0 \, and a decay segment passes through zero at a controllable
+point (the "duty cycle" \, as a percentage of a cycle.) Each has a
+controllable slope (in units per cycle). The resulting triangle wave
+(the minimum of the rise and decay segments) is limited to 1 \, thus
+making a flat "sustain" segment (unless the rise and decay segments
+meet at a value less than one \, in which case there is none). Limiting
+below by 0 prevents us from following the decay segment into negative
+values. Reasonable values to start with are 6 Hz. frequency \, rise
+and decay slope 10 \, duty cycle 75%.;
