The MF-101S Lowpass Filter is a re-invention of the classic Moog MF-101 analog effects pedal. The hardware MF-101 Lowpass Filter, introduced in 1998, contained two complete modular functions: a classic, all-analog 4-pole Lowpass Filter paired with an envelope follower to impart dynamic motion to the filtered sound. Designed by Bob Moog and his engineering team, the MF-101 was a direct descendant of the original Moog modular synthesizers, adapted to process, modulate, and play with inputs ranging from guitar, voice, and synthesizer to any imaginable audio source. The MF-101 Lowpass Filter has been meticulously recreated as the MF-101S, capturing not only the warm and vibrant sound of the original, but also the organic way in which the parameters interact to create a musical playing experience. With CV interconnectivity, stereo functionality, an extended feature set, the ability to run multiple instances, and presets, the MF-101S plug-in further tailors the classic Moogerfooger functionality to the modern digital creator.
