A "supersaw" is a term coined by Roland for their JP-8080 and JP-8000 Analog Modelling Synthesizer. The actual sonic phenomenon is what we like to call phase desync. Phase desync is a synthesis technique to achieve a "chorus" sound. It can be done by using a carrier wave "saw oscillator for example," and modulating its signal using a comb filter where the filter cutoff frequency is usually modulated with an LFO, which the LFO's depth (or amplitude) is equal to the saw oscillator's current frequency. It can also be done by using a copied signal and have the copy run throught a delay which the delay's time is modulated again by an LFO where the LFO's depth is equal to the saw oscillator's current frequency. But most of the time the effect is achived by taking two saw oscillators and detuning one plus or minus an amount of cents away from the other's current frequency. What produces the effect is the sum of two "desynced" waves produces a sum wave, which its timbre changes according to the position of the "desynced" wave of the pair. This produces the "chorus effect" you all love and know.
Put that in your paper!
