This patch allows you to see and hear the sum of up to 16 harmonically-related sinusoidal tones, mixed with equal amplitudes. The sinusoids are all in cosine phase. (If the phases were different, the sum would look different, but it would sound pretty much the same.) As you add a number of tones together, you'll need to adjust the volume to avoid clipping.
This is an algorithmic generator of sound patterns based on the number 6. The patch a) uses the urn object to generate a list consisting of a random ordering of the six digits 0 to 5, b) uses a metro to bang a counter six times per second in order to count through that list of digits, c) uses those six digits to produce six frequencies representing harmonics 7 through 12 of a fundamental (110 Hz, initially), and d)uses those freque
