The VCO Lite from Hampshire Electronics is a compact, high-performance analog oscillator built around the legendary SSI2131 chip. Delivering smooth, musical waveforms and rock-solid tracking, the VCO Lite provides the essential power of a precision VCO in a streamlined Eurorack format.

Designed for reliability and immediacy, this module combines a warm analog tone with simple, intuitive controls — perfect as a standalone sound source, an FM pair partner, or part of a complex modular voice.

Hand-assembled in England, the VCO Lite offers all the classic features you expect from a professional analog oscillator — without unnecessary complexity.

Please note that due to issues sourcing some knobs, the coarse tune / octave knob may be substituted for a different but similar knob.
