ICONIC. VERSATILE. UNCOMPROMISING.

FILTER CLASSICS deliver the unique, iconic sound of the filters from three of the most sought-after vintage synths ever created; the Moog Minimoog, the Roland TB-303, and the Korg MS-20. Modelled exclusively by using cutting-edge DSP based on the same techniques as used in industrial circuit simulators, LADDER, PMS-20, and ACID faithfully capture the rich, analogue character of the original hardware units. With minimalistic, easy-to-use interfaces and unrivalled sonic quality FILTER CLASSICS provides an essential addition to any production toolbox.
