GEN10 — Generate composite waveforms made up of weighted sums of simple sinusoids.
These subroutines generate composite waveforms made up of weighted sums of simple sinusoids. The specification of each contributing partial requires 1 pfield using GEN10.
size -- number of points in the table. Must be a power of 2 or power-of-2 plus 1 (see f statement).
str1, str2, str3, etc. -- relative strengths of the fixed harmonic partial numbers 1,2,3, etc., beginning in p5. Partials not required should be given a strength of zero.

Here is a simple example of the GEN10 routine. It uses the file gen10.csd. It will generate a simple sine wave. Here is its diagram:
