These four paths are used just like the sin path was used above. Try replacing some of the ``sin'' path with some of these other paths. Of course, you can mix and match paths as you prefer: for example, and element's duration could follow the path of a square wave, while its amplitude follows the path of a sawtooth wave.
Here's a datafile to create a sound using all the standard paths, followed by a plot of the paths used.
