The Edge control can also give triangle-like sounds, when used with a 50% 
pulse wave.  From a technical point of view, a triangle and a square wave 
are similar, but the triangle has less high frequency content:

Square = f1 + 1/3 * f3 + 1/5 * f5 + 1/7 * f7 + ...

Triangle = f1 + 1/9 * f3 + 1/25 * f5 + 1/49 * f7 + ...

Turning the Edge to 0 makes a sine wave; turning it to 20-50 makes a 
triangle-like wave.
