symSin
Symmetrical sineshaper with treshold. Above the value set by the knob, the signal will turn into a sine-shape. At this treshold the sineshaper will be at 45degrees, thus at a 1:1 ratio, before curving the signal. This module is alike the sinelord module, but only has a single control for both positive and negative treshold. Use "asymSin" for asymmetrical distortion.
