The Moogerfooger MF-108S Cluster Flux, by Moog, is a plug-in recreation of the classic analog pedal, offering BBD-based chorus, flanging, and vibrato with expanded stereo and CV features.
Core Purpose
The MF-108S Cluster Flux recreates the classic Moog analog effects pedal, focusing on a dual-range Bucket Brigade Device (BBD) delay line and a multi-waveform LFO. It delivers the original subtle swirling and intense flanging sounds, while preserving the organic interaction between parameters for a musical experience.
This plug-in processes any audio source, from guitar and voice to synthesizers, adapting the classic modular synth approach. The recreation captures the original hardware’s character, making it suitable for adding movement and texture in a modern production environment, with presets and multiple instances supported.
Key Capabilities
The MF-108S extends beyond the hardware with switchable TYPE for normal stereo ECHO or PING-PONG delay modes. TONE settings offer Legacy, Analog, and Modern EQ and filtering options, shaping the grit of the delayed signal. TIMING toggles between tight digital or loose, unstable timing, adding flexibility.
The OUT OF PHASE feature enables numerous stereo routings, splitting DRY and WET signals and creating phase-inverted outputs for deeper stereo imaging. The plug-in also supports running multiple instances, allowing complex layered effects that the original pedal couldn’t achieve alone.
Workflow Integration
For creative modulation, the MF-108S provides dedicated CV Inputs for Delay Time, Feedback, LFO Rate, LFO Amount, and Mix. Each CV input includes attenuation capabilities to soften or scale the modulation depth, integrating seamlessly with virtual modular environments or DAW automation.
The stereo functionality and extended features simplify routing in a mix, from adding subtle chorus to busses to creating wide stereo effects on individual tracks. Presets allow quick recall of settings, and multiple instances can be used across different tracks, making the plug-in a versatile tool for sound design and music production.
Practical Applications
Use the MF-108S for classic chorus on guitars, synths, or vocals, or push it into intense flanging for dramatic sweeps. Vibrato effects can be shaped with the LFO, while the TONE and TIMING controls let you tailor the color and stability to fit the track.
The PING-PONG delay mode is ideal for widening stereo mixes, and OUT OF PHASE routines enhance spatial depth. For advanced sound design, CV inputs allow external modulation sources to drive the effect, making it suitable for experimental patches, ambient textures, and rhythmic modulation in modern electronic music.
