Analog VCF Synthesizer Module Behringer WASP 0720-ADB86-001 – Resonant Voltage-Controlled Filter

The Behringer WASP analog VCF module is a voltage-controlled filter designed to deliver the characteristic resonant sound of the original WASP circuit in a compact module format. Intended for integration into Eurorack-style systems or use as part of a modular synthesizer rig, this VCF lets you shape timbre, emphasize harmonics and produce classic filter sweeps and rhythmic filtering effects. It offers hands-on control for live performance and studio sound design where an authentic analog filter response is required.

Advantages

The module provides a resonant filter circuit optimized for musical response, with controls that allow precise adjustment of cutoff and resonance. Its analog architecture preserves harmonic content and yields the warm, sometimes aggressive character associated with the WASP design. The compact form factor enables easy installation into modular setups while maintaining tactile control for live tweaking and sound shaping.

Suitable for

• Shaping timbre and removing or emphasizing frequency bands in analog synthesizer patches
• Creating filter sweeps, peaks and rhythmic filtering effects in electronic music production
• Integration into Eurorack-style modular rigs as a dedicated resonant VCF
• Live performance where hands-on filter manipulation is required

Key specifications

• Analog voltage-controlled filter with resonant behavior
• Controls for cutoff frequency and resonance for tonal shaping
• Compact module form factor suitable for modular synth systems
• Designed to preserve harmonic content and deliver an authentic analog filter character

How to use

Patch the module into your synthesizer system according to your system's power and signal conventions. Route audio into the filter input and take the filtered signal from the output. Use the cutoff control to set the filter frequency and adjust resonance to increase harmonic emphasis and self-oscillation if required. Modulate the cutoff with control voltages from LFOs, envelopes or sequencing sources to create dynamic sweeps and rhythmic patterns. Adjust levels to avoid unwanted distortion unless a more aggressive character is desired.

Usage recommendations

For predictable behavior in a modular setup, ensure proper power connections and respect the voltage ranges of your system. Use moderate resonance when adding subtle harmonic color, and higher resonance settings for pronounced peaks or self-oscillation. Pair with rich analog oscillators or external effects to explore a wide range of timbres and textures.
