The Surprise Drop That Nobody Saw Coming
While everyone was waiting for Behringer’s promised analog delay pedal, the company quietly dropped something completely unexpected: the BM-15M Murf Box. This faithful clone of the legendary Moog Moogerfooger MF-105M MIDI MuRF suddenly appeared on Thomann for pre-order, catching the music community completely off guard.
What Made the Original MF-105M So Special
The Moog Moogerfooger MF-105M MIDI MuRF (Multiple Resonance Filter Array) wasn’t just another filter pedal—it was a sonic playground that combined eight tuned bandpass filters with a pattern generator and envelope follower. Released in 2009, it became the holy grail for electronic musicians seeking that distinctive rhythmic filtering effect that could transform any audio source into complex, evolving textures.
Eight Filters, Endless Possibilities
Like its legendary predecessor, the BM-15M Murf Box features eight analog bandpass filters that process your input signal in sequence. These filters are controlled by both a built-in pattern generator and an envelope follower, creating the signature “talking” effect that made the original so coveted.
Dual Frequency Ranges for Maximum Versatility
The Murf Box includes the MIDI MuRF’s ability to switch between two frequency ranges:
- Mid Range: 110 Hz – 1.8 kHz for vocal-like effects and melodic content
- Bass Range: 200 Hz – 3.4 kHz for low-end emphasis and rhythmic punch
24 Built-In Patterns Plus LFO Control
The built-in pattern generator offers 24 distinct filter patterns, each available with or without an active LFO. Each filter has its own volume control, allowing you to craft complex rhythmic patterns by varying the level of individual frequency bands. An adjustable drive circuit adds extra power and saturation to the output stage.
Modern Connectivity for Today’s Studios
While staying true to the original’s analog heart, the BM-15M brings modern connectivity options:
Audio I/O:
- Mono audio input
- Stereo outputs (L/R)
Control Options:
- TRS inputs for Rate, Mix, Envelope Follower, and LFO/Sweep
- TAP/Step input for manual pattern control
- Expression pedal compatibility
Digital Integration:
- MIDI input for parameter control and sync
- USB-C port for advanced MIDI capabilities
- External power supply input
The €149 Question: How Does It Compare?
At just €149, the BM-15M represents a massive price advantage over vintage MF-105M units, which now command astronomical prices on the used market. The original Moogerfoogers have achieved cult status not just for their sound, but for their build quality and sophisticated design philosophy that treated synthesists and guitarists as equals.
The big question remains: will Behringer include the pattern editor software that made the original MIDI MuRF so powerful? Moog’s original editor allowed users to create custom filter patterns, significantly expanding the unit’s creative potential.
Part of a Larger “Boogerfooger” Vision
The Murf Box represents the latest entry in Behringer’s ongoing effort to clone the entire Moogerfooger line. Previously announced models include:
- BM-101: Low Pass Filter (MF-101 clone)
- BM-103: 12-Stage Phaser (MF-103 clone)
- AD-104: Analog Delay (MF-104 clone)
- BM-107: Frequency Box (MF-107 clone)
The sudden appearance of the Murf Box suggests that Behringer’s Moogerfooger project is further along than many expected.
Why the MuRF Matters in 2025
In an era of digital everything, the MuRF’s analog filtering approach offers something that plugins struggle to replicate: the organic interaction between envelope following, pattern generation, and analog filter behavior. It’s particularly valuable for:
- Electronic Music Production: Adding movement and rhythm to static sounds
- Live Performance: Real-time transformation of any audio source
- Sound Design: Creating complex, evolving textures from simple inputs
- Mix Processing: Adding interest to drums, basslines, and pads
Availability and Expectations
The BM-15M Murf Box is available for pre-order at €149, though no specific shipping date has been announced. Given Behringer’s track record with Moogerfooger clones, expect a waiting period before units actually ship.
The real test will be whether Behringer can capture not just the functionality but the musical character that made the original MF-105M so beloved. At this price point, even a “close enough” approximation would make advanced filtering techniques accessible to a much wider range of musicians.
For producers and performers who’ve been priced out of the vintage Moogerfooger market, the BM-15M Murf Box could represent the return of an iconic effect that helped define the sound of electronic music in the 2000s and beyond.

Hi, I’m Canoy Dang. I grew up in Granada and now living in Málaga, in the south of Spain. Sound has always played a central role in my life — from early home recordings to the deeper, ongoing exploration of the modular synth world. Modular, semi-modular, and desktop synthesizers have become my main tools for expression, experimentation, and sometimes, simply for getting lost in the process.
