SSinOscFB | SuperCollider 3.13.1 Help

Description

SSinOscFB 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.

Arguments:

freq	Audio-rate frequency of the sine oscillator in Hertz.
feedback	Audio-rate amplitude of phase feedback in radians.
mul	Output will be multiplied by this value.
add	This value will be added to the output after any multiplication.
