Polyrhythmix (Poly) is a command-line assistant designed for musicians and composers working in genres such as modern progressive rock, metal, djent, fusion, and Indian Carnatic music. It simplifies the process of creating complex polyrhythmic drum patterns by generating MIDI files based on DSL input. The tool calculates when different drum parts will converge and can also generate a bass MIDI track that follows the kick drum. The author, a guitar player, created Polyrhythmix to have a simple tool to workshop rhythmic ideas and evaluate them through MIDI playback. Users can customize various options such as time signature, tempo, and drum patterns. The software is open for contributions, and users can reach out to the author for support.
