Quadrumvibrate\u00a0demonstrates an approach to directing algorithmic music systems in real time. At the core of\u00a0Quadrumvibrate\u00a0is a performance that unfolds through dynamic interactions between two performers and the generative systems they activate, forming a quartet of human\u2013machine collaborators. The work investigates processes for creating evolving sonic and rhythmic textures derived from algorithmically generated and modulated rhythmic sequences, realised through layered, synthesised percussion.\u00a0<\/p>\n\n\n\n
Rhythm machines have long been central to modern commercial music, yet their role in live experimental electronic performance\u00a0remains\u00a0less explored.\u00a0Quadrumvibrate\u00a0investigates the boundary between pulse\u2011based music and noise-based sound practices through a live, interactive performance featuring two musicians using custom digital instruments that employ generative rhythmic patterns and percussion synthesis. The work examines methods of gestural control over these generative elements, emphasising improvisational expressivity and rich spectral detail. Its new instrument, the Beat Machine S3, extends the legacy of unconventional electronic rhythm generators, such as the Buchla 252e and the\u00a0Ndial, and including the series of Beat Machines<\/a> developed by myself and John Ferguson, to create dynamic, evolving polyrhythmic\u00a0textures.<\/p>\n\n\n\n
