Rebel Technology's Stoicheia Black is a dual Euclidean sequencer that enables users to generate rhythmic sequences algorithmically based on an input trigger signal. This Eurorack module is designed to create complex and unique patterns by implementing the Euclidean algorithm. The module is controlled by a column of three knobs and a switch where each sequence's length is measured in clocks or beats and can range from 1 to 16, with the center position being at 8. The second knob from the top controls the number of on-beats, where fully clockwise sets every beat 'on,' and fully counterclockwise sets only one beat 'on.' The third knob, in the center position, sets every other beat 'on', or 50%.
One of the standout features of the Stoicheia Black is the top knob's function, which adjusts the beat the sequence starts on, allowing users to rotate the sequence left or right. This adds an extra layer of manipulation to the sequencer, providing users with a wide range of possibilities when it comes to creating complex and evolving patterns.
The updated version of the Stoicheia Black doesn't require a 5V rail and is now available in kit form from Befaco Synths. This means that users can easily build the module themselves, providing an excellent opportunity for individuals to learn more about the core principles of modular synthesis.
Overall, the Stoicheia Black is an incredibly versatile module that opens up a world of possibilities when it comes to sequencing. Whether it's creating intricate polyrhythmic patterns or evolving sequences that are constantly shifting and changing, this Eurorack module is a must-have for anyone looking to add a touch of randomness and unpredictability to their music.
Example Usage
If you're new to using the Rebel Technology Stoicheia Black, a great way to get started is by creating a simple drum pattern. To do this, first send a clock signal to both sequencers. Set the sequence length to 4 using the second knob from the top, and the number of fills to 2 using the third knob. Finally, adjust the top knob to select which beat the sequence starts on. Now, experiment with different combinations of knobs and switches on both sequencers to create a variety of interesting rhythms.
An intermediate-level usage example for Rebel Technology's Stoicheia Black is to create complex rhythms by combining both sequencers to create polyrhythms. For example, use the first sequencer to generate a 7-step sequence with 3 fills and the second sequencer to generate a 5-step sequence with 2 fills. Patch the two sequencers' outputs into a logic or gate module, and their gates output to the rhythm generators of your preferred percussion modules. Experimenting with the Stoicheia Black's dual sequencers will offer a new level of rhythmic variation in your electronic music productions.
Further Thoughts
Utilizing the Dual Euclidean Sequencing feature on Rebel Technology's Stoicheia Black module can bring a whole new level of complexity to your Eurorack setup. One creative way to implement this feature is by using it as a control source for a drum machine or sampler. By sending the generated rhythmic sequences to different channels or triggers, you can create intricate beats and polyrhythms that would be difficult to produce manually. Experiment with different sequence length, fill, and start position settings to find the perfect combination for your composition.
