2hp Rash
Eurorack noise source module generating real-time digital noise with a raw, unstable sound.
Overview
The 2hp Rash is a Eurorack digital noise source designed by 2hp. A microcontroller generates the noise algorithmically in real time. The result is a gritty, dynamic texture, described as "alive" compared to static samples. The panel has one knob that sweeps through noise types, one button that works as a manual trigger, and one jack for a trigger input. It has a single audio output. It draws 30mA from the +12V rail and needs no -12V. At 2HP wide, it takes up very little room in a modular system.

Design
The 2hp Rash is a digital module built around a microcontroller that computes noise algorithms in real time. It is not sample-based, resulting in a raw, unstable, and dynamic character. The noise output is described as gritty and unpredictable, evoking sounds like corrupted floppy disks, untuned radio hiss, or vinyl crackle run through a bit-crusher.
Reception
The Rash adds grit, crackle, hiss or digital chaos to modular patches. It does well at glitchy textures and dirty layers. It is not meant for pristine, filtered noise.
