Moogerfooger MF-104S Analog Delay plugin is a digital recreation of Moog’s legendary MF-104 hardware delay pedal. Originally introduced in 2000, the MF-104 quickly became a sought-after effect for its lush, warm analog delay tones. This software version aims to capture the essence of the original hardware while adding modern features for increased flexibility in digital audio workstations. At its core is an emulation of the dual-range Bucket Brigade Device (BBD) delay line, providing delay times from 40 to 800 milliseconds. The plugin preserves the rich, full-bodied character of the analog circuitry, complete with the subtle imperfections and organic qualities that made the original so desirable. Moog has expanded on the hardware’s capabilities by including stereo functionality, extended modulation options, and DAW-friendly features like preset management and automation support.
Pros:
• Authentic emulation of the coveted MF-104 analog delay sound
• Expanded feature set beyond the original hardware capabilities
• Intuitive interface with vintage-inspired design
• Flexible modulation options with multi-waveform LFO
• Stereo functionality for wider soundscapes
Cons:
• Limited to 800ms maximum delay time, which may be restrictive for some users
• Learning curve for users unfamiliar with modular-style patching concepts
The MF-104S Analog Delay plugin boasts an impressive array of features that both honor the original hardware and expand its capabilities for modern production workflows. The delay section offers a dual-range BBD-style delay line, allowing users to switch between short (40-400ms) and long (80-800ms) delay ranges. This preserves the characteristic tonal shift between ranges that was present in the hardware. The Feedback control can push the delay into self-oscillation territory when set above 8, opening up possibilities for experimental soundscapes and dub-style effects.
The LFO section is a standout feature, providing extensive modulation options for the delay time. Users can choose from six waveforms: Sine, Triangle, Square, Sawtooth, Ramp, and Random Stepped. The LFO Rate spans from 0.05 Hz to 50 Hz, enabling subtle chorusing effects at slow rates and wild pitch modulations at faster settings. The Amount control determines the depth of modulation, allowing for anything from gentle wobbles to extreme warping of the delayed signal.
Moog has introduced several modern enhancements in the plugin version. The Type switch toggles between normal stereo echo and a ping-pong mode, creating bouncing stereo image delays. The Tone control affects the EQ, filtering, and grittiness of the delayed signal, with Legacy, Analog, and Modern settings to tailor the effect to different production styles. A Timing control allows users to choose between precise digital timing or looser, more unstable analog-style timing fluctuations.
The Feedback Mode switch is another new addition, determining whether the feedback signal is routed through the entire effect chain or only through the delay line. This flexibility allows for preserving certain sonic characteristics or creating more complex, evolving delay textures.
CV (Control Voltage) inputs for Delay Time, Feedback, LFO Rate, LFO Amount, and Mix provide deep modulation possibilities. These inputs can be controlled by other instances of Moogerfooger plugins or external modulation sources within the DAW, mimicking the interconnectivity of modular systems.
The plugin’s interface is designed to resemble the original hardware, with skeuomorphic knobs and switches that provide a tactile feel even in the digital realm. The ability to save and recall presets, as well as full parameter automation support, brings the classic Moog delay firmly into the modern production environment.
While the 800ms maximum delay time might be limiting for some applications, it stays true to the hardware’s limitations and encourages creative use within these constraints. The plugin’s learning curve, particularly regarding the CV modulation system, may be steep for some users, but it rewards experimentation and deep diving into its capabilities.
When compared to other delay plugins on the market, the MF-104S stands out for its focus on authentic analog emulation. While many digital delays offer pristine, clear repeats, the MF-104S excels at delivering warm, slightly degraded echoes that sit naturally in a mix. Its character is reminiscent of other BBD-style delay emulations like Universal Audio’s EP-34 or Soundtoys’ EchoBoy, but with a distinctly Moog flavor. Unlike some more feature-packed delay plugins such as FabFilter’s Timeless 3 or Valhalla Delay, the MF-104S doesn’t offer multiple delay algorithms or extensive routing options. Instead, it focuses on perfecting a single, characterful delay type. This makes it less versatile but potentially more appealing to those seeking a specific analog color. The modulation capabilities of the MF-104S are more extensive than many dedicated delay plugins, putting it in competition with modulation-heavy effects like Eventide’s UltraTap or Unfiltered Audio’s Sandman Pro. However, its modular-inspired CV inputs set it apart, offering a unique approach to parameter control that will appeal to experimental producers and sound designers.
This plugin is best for:
• Producers seeking authentic analog delay tones in a digital environment
• Sound designers looking for creative modulation possibilities
• Musicians wanting to add warmth and character to digital recordings
• Moog enthusiasts unable to acquire the original hardware
• Electronic and experimental music producers
The Moogerfooger MF-104S Analog Delay plugin successfully translates the beloved sound of the original hardware into the digital domain while expanding its capabilities for modern music production. It captures the essence of analog delay—warm, slightly lo-fi, and full of character—while providing the convenience and flexibility of software. The addition of stereo functionality, extended modulation options, and CV inputs opens up new creative possibilities that weren’t available in the original hardware. For producers and musicians seeking to add genuine analog flavor to their digital productions, the MF-104S offers a compelling option. Its ability to range from subtle tape-like echoes to wild, modulated soundscapes makes it a versatile tool for various genres. The attention to detail in emulating the original hardware, combined with thoughtful modern additions, results in a plugin that bridges the gap between vintage charm and contemporary functionality. Whether used for adding depth to a mix, creating atmospheric textures, or as a sound design tool, the MF-104S Analog Delay plugin stands as a worthy successor to its hardware predecessor and a valuable addition to any digital effects arsenal.
