Moogerfooger MF-107S FreqBox is a digital recreation of Moog’s classic analog effects pedal, bringing the unique sound and functionality of the original hardware into the digital realm. This plugin captures the essence of the MF-107 FreqBox, which was introduced in 2007 as a direct descendant of Moog’s modular synthesizers. The MF-107S combines several modular synth functions, including a voltage-controlled oscillator (VCO) with variable waveshape, hard sync capabilities, and frequency modulation by audio input. It also features an envelope follower that allows the dynamics of the input signal to modulate the VCO frequency. The plugin faithfully emulates these features while adding modern conveniences such as preset management, multiple instances, and enhanced stereo functionality. The MF-107S FreqBox is designed to process, modulate, and transform a wide range of audio sources, from guitars and vocals to synthesizers and drum machines, offering a distinctive palette of sounds ranging from subtle thickening to wild, jagged tones.
Pros:
• Accurately recreates the unique sound and behavior of the original hardware
• Offers extensive modulation options with CV interconnectivity
• Includes modern features like stereo processing and preset management
• Provides a wide range of tonal possibilities, from subtle to extreme
Cons:
• Learning curve may be steep for users unfamiliar with modular synthesis concepts
• Some users might find the interface overwhelming at first
The MF-107S FreqBox boasts an impressive array of features that make it a powerful tool for sound design and audio manipulation. At its core is a voltage-controlled oscillator (VCO) with variable waveshape, capable of producing a range of tones from sine waves to sawtooth and beyond. This oscillator can be hard synced to the input signal, creating classic synthesizer sync effects. The frequency of the VCO can be modulated by the input signal, allowing for complex FM-style sounds.
One of the key components of the FreqBox is its envelope follower. This feature analyzes the dynamics of the input signal and uses that information to modulate various parameters. In the original hardware, and replicated in this plugin, the envelope follower can control both the frequency of the VCO and the level of the effect. This creates a dynamic, responsive effect that reacts to the nuances of the input signal.
The plugin offers two modes for the oscillator: MONO and STEREO. In MONO mode, it behaves like the original hardware, using a single oscillator for both left and right channels. The STEREO mode introduces two independent oscillators, one for each channel, allowing for more complex stereo effects and preserving the stereo image of the input signal.
The ENVELOPE CONTROLS setting allows users to choose whether the envelope follower affects both the frequency and level of the FreqBox effect (as in the original hardware) or only the frequency. This latter option can create interesting drone-like effects where the FreqBox is always present. MF-107S includes extensive modulation options through its CV (Control Voltage) inputs. Users can modulate parameters such as Oscillator Frequency, Waveform, Envelope Amount, FM Amount, and Mix. The plugin also includes digital attenuverters for each CV input, allowing for precise control over the modulation depth and polarity.
A unique feature of the Moogerfooger plugin series is the ability for multiple instances to interact with each other within a DAW session. This recreates the patching capabilities of the original hardware units, allowing for complex modulation routings and creative sound design possibilities.
The user interface of the MF-107S is designed to closely resemble the original hardware, with skeuomorphic knobs and switches that provide a familiar experience for those who have used the physical unit. However, it also includes modern conveniences such as a preset browser, allowing users to quickly save and recall their favorite settings.
When comparing the MF-107S FreqBox to similar plugins, it stands out for its unique approach to sound manipulation. While many synth plugins offer oscillators and modulation options, the FreqBox’s combination of VCO, hard sync, FM, and envelope following creates a distinctive sound that’s hard to replicate with other tools. Its ability to process external audio sets it apart from traditional synthesizer plugins. In terms of modulation and CV routing capabilities, the MF-107S is comparable to modular synth emulations like VCV Rack or Softube Modular. However, it offers a more focused, streamlined experience that’s specifically tailored to the FreqBox concept. When it comes to creating synth-like effects from audio input, the FreqBox can be compared to plugins like Output’s Signal or Native Instruments’ The Finger. However, the MF-107S offers a more analog-inspired sound and behavior, staying true to its hardware origins.
This plugin is best for:
• Sound designers looking for unique ways to manipulate and transform audio
• Electronic music producers seeking to add analog-style grit and character to their tracks
• Experimental musicians who enjoy pushing the boundaries of conventional sounds
• Film and game composers needing to create otherworldly sound effects
• Producers working with drum machines who want to add synth-like elements to their beats
Moogerfooger MF-107S FreqBox is a powerful and versatile plugin that brings the unique sound and functionality of Moog’s classic hardware into the digital domain. It excels at creating a wide range of sounds, from subtle thickening and harmonization to wild, aggressive tones. The plugin’s strength lies in its ability to react dynamically to input signals, creating organic, evolving sounds that can breathe life into static audio material. While it may have a learning curve for those unfamiliar with modular synthesis concepts, the MF-107S rewards experimentation and can lead to unexpected and inspiring results. Its extensive modulation options and ability to interact with other instances of Moogerfooger plugins make it a valuable tool for complex sound design tasks. Whether used subtly to add character to a track or pushed to extremes for experimental sound creation, the MF-107S FreqBox is a plugin that can find a place in many different musical contexts, from electronic and ambient to rock and hip-hop production.
