-#X text 172 364 this makes a quick-and-dirty triangle wave;
-#X text 172 382 as described in the previous patch. It's;
-#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%.;
