Unlike a "sawtooth animator" the Super Sawtor doesn't simulate several phase-shifted oscillators creating an ultra-wide sound but it adds harmonics to the input signal. Best results are achieved when using a sawtooth at the input, resulting in a supersaw, but the module works well with other waveforms, too.
The Spread parameter sets the amount of the detune of the new harmonics, both manually and voltage controlled. The Mix potentiometer controls the effect amount.
The module is entirely analog and has no aliasing or whatsoever.
