What it does

The MF-107S FreqBox is Moog's plugin version of the MF-107 Moogerfooger pedal, which Moog calls "a direct descendant of the original Moog modular synthesizers." Instead of only processing the input, it adds a synth oscillator that the input signal syncs, modulates and drives: in Moog's words, "a box of gnarly synced VCO sounds."

Oscillator: a VCO with a range of about 25Hz to 1.6kHz and variable waveshape across triangle, sawtooth, square and pulse, in MONO or STEREO mode.
Hard sync: the oscillator can be hard-synced to the input, giving fizzy, edgy high-frequency tones laid over the source.
FM: linear frequency modulation of the oscillator by the input signal, for synthetic drones, clusters and pitch-obliterating textures.
Envelope follower: the input's dynamics control the oscillator's FREQUENCY and LEVEL, or FREQUENCY only.
Mix: blends the oscillator output with the dry signal, so the source can stay audible underneath.
CV inputs: virtual CV inputs for Oscillator Frequency, Waveform, Envelope Amount, FM Amount and Mix, each with attenuation, plus presets and multiple instances.

It is also part of Moog's bundle of seven Moogerfooger plugins.

When to use it

FreqBox is the pick when you want to generate new, synth-like sound from an input rather than run it through a chain of effects. Compared with Infiltrator 2 or Multipass, it does one thing, with no effect chain, filters or modular routing, but its synced and FM oscillator tones are something those multi-effects don't offer in the same form. It behaves somewhat like a distortion with a much more synthetic, unpredictable character. Next to Effect Rack, it is narrower in scope but far stranger in sound.

Best for: snarling, sync-style synth tones from guitar, bass and synths, and experimental or Radiophonic-style effects on drums and vocals.
Genres: electronic, experimental, rock and sound design.
Look elsewhere if: you want predictable, musical processing or a conventional effect chain; Infiltrator 2 or Multipass suit that better.
Tip: Sound On Sound suggests treating it as a 1960s-style tone generator for Radiophonic effects rather than an everyday processor.

What producers say

Reviewers found it wild and creative, but hard to control for conventional music.

MusicRadar (Robbie Stamp, 2022) said it turns a niche pedal into a versatile plugin that adds "snarl, fizz and warped distortion" to basses, leads, arps, drums and vocals, and works well in CV-linked chains.
Sound On Sound (Robin Bigwood, 2023) described it as "chaotic and uncontrollable" yet creative, with sync giving fizzy distortion and FM producing Dalek-like drones.
Criticisms: Sound On Sound found its output often "anti-musical" and best suited to Radiophonic-style effects; the bundle also lacks MIDI Learn and resizable windows.
