The Behringer 121 Dual VCF Eurorack module brings the classic filter sounds of vintage modular synthesizers to your Eurorack system. With two voltage-controlled filters based on 1980s circuitry, you can shape and modulate your sounds for endless sonic creativity.

Dual Vintage VCFs

At the heart of the 121 are two voltage-controlled filters that recreate the warm, rich sound of classic analog filters. Each low-pass VCF has its own resonance control to emphasize harmonics as well as a cutoff knob to sweep the filter frequency. Create anything from smooth, rounded tones to aggressive, biting textures. Whether you're looking for subtle movement or wild, animated effects, the 121's filters give you the tools to take your sound design further.

Explore Complex Modulations

For dynamic filter modulation, each VCF provides 3 CV inputs with individual attenuators, allowing you to blend LFOs, envelopes and other CV sources. Create slowly evolving pads, pulsating basslines and rhythmic filter sequences. The creative possibilities are endless when you combine the 121 with sequencers, envelopes and LFOs from your system.

Add Vintage Character to Your Eurorack Rig

Designed for Eurorack, the 121 seamlessly integrates with your existing modular gear. Connect it to your VCOs, submixes and other sound sources to infuse your patches with classic analog filter flavor. Dial in the signature warmth and movement that defined the sound of vintage synths. Whether you're just starting out in Eurorack or looking to add more modular power, the 121 Dual VCF lets you explore vintage filter tones without the vintage price tag.
