Zlob Modular - Entropy Noise/Random Source 3hp - Sample and Hold / Track and Hold - Smooth Random

Zlob Entropy Sample and Hold/Random Module

The Zlob Modular Entropy is a compact 3HP analog random voltage and noise generator for Eurorack systems. It combines sample/track and hold functionality with multiple analog noise sources, giving you a flexible source of unpredictable CV, stepped random voltages, smooth random movement, and noise-based patching in a very small footprint.

The sample/track and hold section is normalled to white noise and can be switched between sample & hold or track & hold operation. A PCB trimmer lets you adjust the spread of the random voltage output, from smaller scalar movement to wide interval jumps. Entropy also provides analog white, pink, and brown noise outputs, plus a smooth random CV output with two range settings for anything from wiggly modulation to slower, envelope-like random motion.
