About this plugin
The MF-105S MuRF represents a faithful digital recreation of Moog's landmark multi-resonant filter array, originally designed in the early 2000s as a direct application of modular synthesizer filter topology to real-time audio processing. The plugin's core architecture comprises eight parallel resonant filters that can be tuned across either bass or midrange frequency regions, with independent level control over each band. The real musicality emerges from the included Animation module, which generates envelope sequences that modulate filter levels in real time, creating distinctive swept and animated tonal effects that feel organic rather than mechanical.
Unlike static graphic EQs, the MuRF's resonant design imparts a characteristic colored tone that emphasizes the musical interaction between filters during modulation. The stepped animation patterns transform ordinary audio sources into rhythmically complex, glitchy textures or smooth, vowel-like modulations depending on source material and parameter settings.

The plugin's modernized feature set includes stereo processing, CV interconnectivity for modulation from other sources, preset management, and the ability to instantiate multiple instances. This expands the original pedal's workflow significantly while maintaining the sonic character that defined the hardware version.
The MuRF occupies a specific niche: producers working with rhythmic material, experimental guitarists, and sound designers seeking characterful, non-linear filtering rather than surgical precision. It excels on drums, percussion, synthesizers, and vocals. While less suited to transparent tone-shaping, its strength lies in generating movement and texture that feels deliberately designed rather than algorithmic.
