The NonlinearCircuits Stochaos Eurorack module is a versatile generator of gates and control voltages that can be switched to produce either pink noise, chaos, or both. The module is based on a 1980 patent for a random rhythm pattern generator, and uses CMOS chips that are widely available. The result is a powerful and creative module that offers a unique approach to noise generation in the Eurorack format.
The Stochaos module provides a range of outputs, including gate and CV outputs, with CV3 being mainly negative voltage. The Stochaos output provides longer gates than other stages in the circuit, making it ideal for generating complex rhythms and patterns. The module also features a reset input that allows you to start the pattern from scratch, providing even more creative possibilities.
One of the standout features of the Stochaos module is its ability to generate both random and chaotic patterns. This gives you the ability to create complex and unpredictable patterns that are perfect for experimental and avant-garde music. By selecting the "Both" option, you can combine the two patterns to create something truly unique.
The module also includes pink noise generation, which can be useful for creating atmospheric textures, as well as adding depth and character to other sounds. Pink noise is a type of noise that has equal energy across a wide frequency range, making it ideal for use as a sound source or as a modulator.
Overall, the NonlinearCircuits Stochaos module is an excellent choice for anyone looking for a powerful and creative noise generator in the Eurorack format. Its unique ability to generate both random and chaotic patterns, combined with its range of gate and CV outputs, make it a versatile tool for any electronic musician or sound designer. Whether you're exploring the outer reaches of noise and experimental music, or looking to add some character and depth to your existing sounds, the Stochaos module is a must-have addition to any Eurorack setup.
Example Usage
If you're new to the NonlinearCircuits Stochaos Eurorack Module, a fun way to experiment with it is to send a gate to IN and set the switch to BOTH. You'll hear a mix of random and chaotic gates and control voltages. Try routing the gate signals to different sound sources or effects and see what unique sounds you can create. Don't be afraid to experiment and embrace the creative chaos!
An intermediate usage example for the NonlinearCircuits Stochaos Eurorack Module is to use it as a source of random modulation for a VCO. Patch the gate output to trigger an envelope generator that controls the VCO's frequency, set the chaos/random switch to 'BOTH', and CV3 to the VCO's frequency input. This will result in an unpredictable and ever-changing frequency modulation that can add unique character and texture to your sound design. Tweak the CV1 and CV2 inputs to manipulate the amount and direction of the modulation, and experiment with different settings to see how the Stochaos module can navigate the border between order and chaos in your modular setup.
Further Thoughts
One of the most interesting and powerful features of the NonlinearCircuits Stochaos Eurorack module is its ability to generate chaotic control voltages. By selecting the "CHAOS" mode, you can create complex and unpredictable patterns that can add a unique flavor to your music. For example, you could use the chaotic CV signal to modulate the cutoff frequency of a filter, creating constantly evolving textures and timbres. Or you could use it to control the pitch of an oscillator, creating a sequence of notes that are at once dissonant and compelling. The possibilities are endless, and the Stochaos module is an essential tool for any electronic musician interested in exploring the creative chaos of modular synthesis.
