Taking bold inspiration from a classic MF-style analog effects pedal, the Behringer BM-15M Resonance Filter will infuse your sound with an exhilarating sense of motion, groove, and life. The Filter section contains an 8-band array of resonance filters that you can rhythmically enhance with the 12 sequenced patterns in the Animation section. Ripe for pairing with electric guitars and synthesizers, the BM-15M unleashes fast, percussive sequences and slow, evolving textures with equal aplomb. Moreover, the Envelope knob yields dynamic, expressive modulations that you can accelerate or decelerate with the Rate knob. The aspect of the BM-15M we found most invigorating here is the USB/MIDI features, which let you lock the effect to the beat or, with the help of an expression pedal, take a more hands-on, real-time approach to control. You also get a Mix knob for blending between the Audio In signal and the BM-15M’s stereo Audio Outs. Boasting a compact, rugged design with vintage MF-style aesthetics, the BM-15M Resonance Filter culminates in a sonic playground that invites both precision tweaking and spontaneous exploration.
