An 8 voice additive synthesizer. Based upon Polyphonic Additive Synthesizer by wet-noodle. This is a 20 partial additive synthesizer, where each partial is attenuated by 1/n, where n is the harmonic number. Knob one controls transposition (+ / – two octaves). Knob two controls the mix between odd and even partials. The setting 0 (knob two fully left) will give you an additive square wave, while putting knob in the center (.5) will give you an additive sawtooth wave. Knob 3 is the attack and release value (values are the same). Knob 4 is the amount of partials applied to the sound, so when this knob is at 0, you will hear only a sine wave (the fundamental). To get a full spectrum, crank it up to 100%.
