MF-105S MuRF
A groundbreaking effect combining a resonant filter bank with a pattern generator and skewing envelope for vibrant animation of an incoming sound
The MF-105S MuRF is a re-invention of Moog Music’s classic MF-105 analog effects pedal.
The MF-105 MuRF (Multiple Resonant Filter Array), originally introduced in 2004, contained two basic functions: an 8-band array of resonant filters that can be voiced for bass or mid frequency response, and a pre-programmed ANIMATION module that generates sequences of envelopes that modulate the levels of the 8 filters. Designed by Bob Moog and his engineering team, the MF-105 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-105 MuRF has been meticulously recreated as the MF-105S, capturing not only the distinctive 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-105S plug-in further tailors the classic Moogerfooger functionality to the modern digital creator.
The MF-105S also introduces unique features not seen on the hardware instrument, including:
PATTERN EDITOR allows for editing of the pre-programmed ANIMATION modulation patterns of the original or creation of your own.
MODE sends all eight filters to both the left and right channels, or splits filters for STEREO spread.
ENVELOPE MODE switches between the original envelope shapes or a new alternate bank of envelopes.
The MF-105S offers CV Inputs for Animation Pattern Rate, Internal LFO Rate, Envelope Shape, LFO Amount, and Mix, as well as the capability to attenuate or soften these modulations.
The Moogerfooger Effects Plug-ins range from clean filtering to wildly experimental modulation designed to manipulate, enhance, and fully transform any sound. Each with its own distinct identity, these effects are designed to work perfectly alongside one another in your audio chain.

This video demonstrates using the MF-105S MuRF to process several sounds generated from a eurorack modular synthesizer in a mix. The MuRF is a versatile processor that can be used for EQing, filtering, and spectral animation of a signal. The MF-105S is a unique way to incorporate classic Moog filter bank sounds into your DAW tracks.
