This patch allows you to see the effect of different exponents in a formula that maps input values to output values with a power function. Input values between 0 and 1, taken to some power, will always yield output values from 0 to 1, provided that the exponent is greater than or equal to 0. (When the exponent is 0, the output values will all be 1.
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.
