Random Source Generator
The Random Source Generator is a powerful hybrid module combining classic analog randomness with precision control. It merges a dual random voltage generator with a high-quality Sample & Hold (S&H) circuit—perfect for adding unpredictability, texture, and character to your patches.
The top section features the legendary Serge-style White & Pink Noise Generator, alongside two distinct random voltage outputs: a unipolar 0–5V and a bipolar ±2.5V, giving you versatile modulation sources for everything from subtle variations to chaotic shifts.
The bottom section houses a precision Sample & Hold circuit with an integrated manual trigger button, letting you capture and freeze voltages on demand or via external clocking.
One of our favorite creative uses? Patch an audio signal into the S&H input and clock it at audio rate to turn it into a gritty, lo-fi bit crusher—a simple patch with wild sonic results.
Whether you're sculpting ambient textures or designing generative sequences, the Random Source Generator is an inspiring tool for experimental sound design.

** 4U Modular is a term used for the format most commonly known as “Serge Format” or “Loudest Warning Format”. Out of respect for the ever growing format, 4U Modular is the easiest way to refer to it. More Specifically it refers to the panel height and mounting hole style. 4U Modular will patch up just fine with other 4U "Serge" formats such as "Random Source", but it will not mount in RS boats or Buchla Boats (or power off Buchla power for that matter). An info page about this will be added to the website soon to make this a lot more easy to understand.
