The Frisson Eurorack Module by Nonlinearcircuits is an electronic music device that leverages the Mackey-Glass equations to generate natural complex chaos in sound patterns. It features a three-part system made up of a nonlinear stage, a low pass stage, and a delay stage. The delay stage is a careful fusion of 8 Bessel filters configured for sub-audio rates, voltage-controlled via Light Dependent Resistors (LDRs), much like an 8-stage phase shifter. Each filter stage has an individual output to the front panel, enhancing the range of sound generation possibilities.
The module also includes an external input to introduce signals into the chaotic configuration, promoting unique auditory experiences. Frisson’s control mechanisms allow the user to adjust the frequency of the chaos via control voltage (CV) or manually. Notably, the module is designed to self-oscillate, operating without any input. With Frisson, users can switch to CV Phaser mode, transforming the Bessel filter section into a voltage-controlled CV Phaser with 8 differing outputs.
Frisson’s adaptability extends to its end-user customization. Users can specify the operating frequency range of the module to their desired pace by adopting capacitor values given in the Build Notes. By harnessing the flexibility of the Frisson Eurorack Module, electronic music enthusiasts can engineer an expansive realm of sound patterns that are both chaotic and harmonious.

The Nonlinear Circuits Snake Joke is a Eurorack module, designed by Tom Hirst, that condenses Euclidian rhythm generation and control voltage (CV) modulation within a minimalistic design based on three CMOS chips. It primarily functions as a Euclidian trigger, gate, and CV generator, providing an even distribution of triggers over 16 steps.
User interaction is facilitated through onboard switches or external signal inputs to control the number of triggers per step. In addition, the Snake Joke allows patching in gates to switch patterns dynamically, adding an element of unpredictability to sequences. Internally, the module utilizes circuit switching to deliver multiple gate outputs labeled C1-4, serving as primary options for shaping your patterns.
The module also features CV output capabilities via a direct-to-analog resistor network attached to C1-4, covering a 0-5V range. This enables the module to interact with other components of the Eurorack system, expanding modulation possibilities and integrating sequences into broader soundscapes.
A key limitation of Snake Joke compared to microprocessor-based Euclidian pattern generators is its fixed 16-step patterns. However, careful use of reset input and switch configurations can mitigate this limitation.
The Snake Joke module affords a unique approach to rhythm composition, emphasizing spontaneity and unpredictability within the generated patterns. Therefore, it requires an open approach to music creation, embracing off-beat patterns and allowing them to fuel creativity.

The article provides an in-depth exploration of several Eurorack modules: the SH5-VCF, Grids MK2, Chance Delay, and Fracture.
The SH5-VCF module is an all-analog adaptation of the Roland SH-5 mixer and Dual Filter. It features a Voltage Controlled Filter (VCF) with High Pass, Low Pass, and Band Pass configurations, along with a dedicated Band Pass Filter circuit, aiming for versatile sound shaping possibilities.
The Grids MK2 made by Blue Lantern Modules is a percussion and Euclidean sequencer that simplifies percussion sequences creation. It offers user-friendly interfaces and internal clock sources.
The Chance Delay module, developed by AJH Synth, introduces randomness into Eurorack setups, offering functionalities like pulse delay, pulse conditioning, and clock division. This module grants users manual and CV control options to fine-tune chance factors, delay times, and pulse lengths.
Finally, WMD’s Fracture module is a multi-particle percussion synthesizer utilizing granular synthesis methods and proprietary micro-samples. It provides extensive sound design possibilities including control over density, decay, tail, stereo output, reverb, trigger inputs, filter types, envelopes and voltage-controlled parameters.
When combined, these modules allow users to create a diverse range of sound design techniques, rhythmic patterns, and experimental sonic landscapes.
