Bringing a Classic Filter Effect Back to Life
The BM-15M resonance filter revives a distinctive style of filter-based modulation first introduced by Moog’s MF-105 MuRF (Multiple Resonance Filter Array). Known for its ability to create rhythmic movement and sonic animation, the original MuRF became a cult favourite among experimental guitarists, electronic artists and producers looking to bring their sounds to life. Behringer’s version pays tribute to the original with a faithful analog-inspired design, while adding useful modern features like USB and MIDI control. At the centre of the BM-15M are eight band-pass filters, each tuned to specific frequency bands. These filters are animated by preset rhythmic patterns that adjust the filter gains over time. The result is a sequence-like effect that imparts motion to static sounds—turning simple chords, pads, or sustained notes into pulsating textures and evolving tonal layers.
What makes the BM-15M particularly flexible is its envelope control, which reacts dynamically to your playing. This gives the effect a touch-sensitive quality, enhancing the musicality and keeping things interactive. It can respond subtly for gentle pulses or more aggressively for staccato-style filtering, depending on how the envelope is set. Modulation speed is handled via a rate control, allowing for both fast, rhythmic patterns and slower ambient washes. The resonance knob adds harmonic emphasis, letting certain frequencies stand out for a more pronounced filter effect. For those who prefer a blend of effect and original tone, the mix control makes it easy to dial in just the right amount of movement without overwhelming the source signal.
Modern Updates
Integration into modern setups is made simple thanks to USB and MIDI inputs. Syncing with external hardware, DAWs or drum machines is straightforward, making the pedal a natural fit in tempo-locked environments. Using the free Guitar Tribe app, users can access deeper editing functions, build custom animation patterns, and store an unlimited number of presets—all from a computer interface. The inclusion of an expression pedal input provides hands-on control during live performances, allowing players to adjust parameters like rate or mix in real time. This adds a level of performance interactivity not always found in modulation effects, especially those as complex as sequenced filters. Physically, the BM-15M is housed in a rugged, compact chassis that’s ready for travel or stage use. Despite its complex internal engine, it fits neatly onto a pedalboard and integrates well with other effects—especially delay, reverb or overdrive units that can accentuate its rhythmic capabilities.
For those familiar with modular synthesis or vintage filter arrays, the BM-15M offers a familiar but more accessible experience. For those new to the concept, it opens the door to a different style of modulation—one that isn’t just about swirling phasers or auto-wahs, but about programmed motion and dynamic tone shaping.
The Behringer BM-15M resonance filter will be available in Australia from late September to early October 2025. To explore specs and software options, visit www.behringer.com.
