With the BM-15M Resonance Filter, Behringer presents a clone of the MoogMF-105 MIDI MuRF from the popular MoogerFooger series. The Resonance Filter is basically a filter bank with eight frequency bands that is modulated with the built-in Pattern Animator. If you leave out all modulations, you can anharmonize the incoming audio signal at the input and then filter it frequency-selectively. But that's only half the fun with this iconic filter box. It gets really exciting with the pattern animator! This runs either at its own tempo or in sync with MIDI-Clock and contains 24 patterns that drive the eight envelopes. The patterns are distributed over 2x 12 patterns, as different patterns are provided for the BASS and MIDS sections of the filter bank. This means that completely different results can be achieved not only rhythmically but also in terms of the frequency image. Each filter band is modulated with its own envelope, creating very lively and, above all, unique filter sounds in the context of the trigger patterns, which only very few devices can master in this complexity.
Enough connections for analog setups
The connections are the same as on the original: there are four CV/expression inputs for the Rate, Mix, Envelope and LFO/Sweep parameters. This allows the parameters to be controlled via an expression pedal or any control voltages from the modular system. The audio input is mono, the audio outputs have a special feature: if you only use the L/Mono socket, all filter bands are routed to this output; if you also use the right socket, the filter bands 200, 450, 1K and 2.2K are distributed to the left output and 300, 675, 1.5K and 3.4K to the right output. An external clock signal (e.g. from an analog sequencer) can be connected to the tap/step input. The pattern animator can be synchronized to MIDIClock via the MIDI input and all parameters can also be controlled via Control Change commands. The USB port is primarily intended for configuring the pedal with the SynthTribe-App.
