INPUT ONE
LARYNX
/// EURORACK MODULE
Inject raw, electrical chaos into your Eurorack system. Here you can download the complete Gerber files to build the LARYNX—a filthy, 555-timer based noise generator and modulator. This module blurs the line between an erratic sound source and an unpredictable CV generator. Driven by pure, unpolished circuitry, it delivers rhythmic clicks, digital debris, and brutal signal mutations. The download includes all necessary PCB files for manufacturing. Grab your soldering iron, embrace the grit of the underground, and start building. Completely free download.

INPUT ONE
ATTENUATOR
/// EURORACK MODULE
Tame your wild modulation signals without using power. Here you can download the complete Gerber files to build the Triple Passive Attenuator. Is your LFO too aggressive, tearing your filter cutoff apart with every cycle? This passive module acts as a simple volume knob for your control voltages. No magic, just pure physics. It requires absolutely no power from your bus board—just potentiometers wired between input and output jacks. Grab your soldering iron, print the boards, and take back control. Completely free download.
