<h2><a class='anchor' name='description'>Description</a></h2>
<p>SinOscFB is a sine oscillator that has phase modulation feedback; its output plugs back into the phase input. Basically this allows a modulation between a sine wave and a sawtooth like wave. Overmodulation causes chaotic oscillation. It may be useful if you want to simulate feedback FM synths.<h2><a class='anchor' name='classmethods'>Class Methods</a></h2>
