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 files gen10.orc and gen10.sco. It will generate a simple sine wave. Here is its diagram:
