Raw Analog Destruction & Tube Self-Oscillation

STIGMA is not just a module: it is a destructive, versatile analog sonic organism, powered by real vacuum tubes and designed to disrupt your Eurorack ecosystem.

Built with a flexible True Stereo and Dual Mono architecture, STIGMA offers total control over signal routing, allowing you to process independent sources or shape the stereophonic space with dense, harmonically rich tube saturation.

From Signal Processor to Pure Synthesizer
While STIGMA is designed to filter, mangle, and brutally distort any external source (drum machines, oscillators, full mixes), it also hides an autonomous and unpredictable soul.

By driving the filter into self-oscillation, the module transforms into a fully-fledged solo synthesizer or a formidable percussive sound generator. By modulating the resonance and leveraging the lightning-fast response of its circuitry, STIGMA can sculpt devastating kicks, metallic toms, and thick, industrial percussive textures, saturated directly by the tube stage.

Key Features:
True Stereo & Dual Mono: Two completely independent tube channels for maximum routing flexibility.

Warmth & Destruction: A tube saturation and distortion stage to go from subtle analog warmth to harsh, destructive clipping.

Advanced Filtering: Analog filters molded around the tube character, capable of cutting through the mix or screaming when pushed to the limit.

Self-Oscillation & Percussive Engine: Generate heavy kicks, industrial toms, and unique percussive sounds by using the circuit's self-oscillation as a sound source.

Eurorack Interface: Integrated CV controls for total, dynamic interaction with the rest of your modular system.
