XiiixxiQ is a unique step sequencer that combines non-linear, polymetric, and polyrhythmic elements to create complex rhythmic patterns. It integrates up to four summed Euclidean rhythm generators, delivering intricate sequences that evolve dynamically. Designed primarily as a MIDI FX plugin for Logic, it offers considerable flexibility in rhythm creation, allowing users to explore a wide range of musical ideas within their projects.

This sequencer features advanced morphing capabilities, including two modes: a 2-dimensional A/B blend and a 3-dimensional A/B/C triangulation, enabling smooth transitions between different rhythmic setups. Additionally, it supports subset sequencing, which analyzes common rhythmic patterns across generators to create evolving sequences that shift naturally over time. Users can also input a custom rhythm pattern, either to drive the sequencer independently or to enhance the overall rhythmic output, expanding creative possibilities.

XiiixxiQ can operate in various environments, including Blue Cat's Patchwork as both a MIDI FX plugin and standalone application, with features to address timing nuances such as note-off event handling. The plugin also includes pattern matching functionality that allows Euclidean generators to closely mimic custom rhythms for further manipulation. A comprehensive manual accompanies the installation, ensuring users can fully utilize the sequencer's extensive features to craft rich, evolving rhythmic textures.
