The Koma Elektronik SVF201 is a Eurorack-format filter module that combines two classic filter designs: a state-variable filter (SVF) and a low-pass gate (LPG). It offers a wide range of sounds, from smooth, creamy low-pass filtering to aggressive, distorted high-pass filtering. The SVF201 also features a built-in envelope follower, allowing it to be used as a voltage-controlled amplifier (VCA), as well as a slew limiter for creating smooth transitions between filter settings. The module is ideal for adding character and texture to any Eurorack system.
