These subroutines generate stored functions as sums of sinusoids of different frequencies.

In each case the composite wave, once drawn, is then rescaled to unity if p4 was positive. A negative p4 will cause rescaling to be skipped.

Here is a simple example of the GEN10 routine. It uses the file <a class="ulink" href="examples/gen10.csd" target="_top"><em class="citetitle">gen10.csd</em></a>. It will generate a simple sine wave. Here is its diagram:
