Toxic Biohazard is the 4th generation in the line of Toxic synthesizers. Toxic Biohazard distills the best features from the previous 3 versions to deliver our most concentrated Toxic ever. Beware! Toxic Biohazard features a hybrid synthesis engine, combining the best of FM and Subtractive synthesis. With the addition of a warm, analog-modelled filter and set of built-in effects, the Toxic concept remains one of convenience, simplicity, and superb sound quality.
