Behringer CHAOS Eurorack Random Voltage Generator Module (16 HP)

Unleash the power of deterministic chaos with the Behringer CHAOS, a 16 HP Eurorack module that generates complex, non-repeating voltage patterns based on the Lorenz Attractor. With three CV outputs (X, Y, Z) spanning -5V to +5V, this analog random voltage generator breathes life into your patches, offering endlessly evolving modulation for filters, oscillators, and effects.

Overview

The CHAOS module is a true analog random voltage generator built around the Lorenz Attractor algorithm, a mathematical model known for its chaotic yet deterministic behavior. It produces three correlated control voltages that wander unpredictably, perfect for adding organic movement to your modular setup. The module features dedicated attenuators for each output, allowing you to scale the voltage range to suit your needs, and CV inputs for Rate, Damping, and Offset enable dynamic control over the chaos parameters.

What stands out

• Analog Lorenz Attractor chaos engine for unique, non-repeating modulation
• Three simultaneous CV outputs (X, Y, Z) with individual attenuators
• CV control over Rate, Damping, and Offset for evolving patterns
• Compact 16 HP Eurorack format with shallow 35 mm depth
• Low power consumption: only 50 mA on each +12V and -12V rail
• LED indicators for each output to visualize signal activity
