Compositor Software is an independent audio software project founded by Moscow-based musician, sound engineer, and programmer Ruslan Yusipov. The operation specializes in algorithmic composition tools and real-time generative audio systems, with a particular focus on techno, ambient, and experimental sound. Much of the catalog is built in Max/MSP, and several tools ship as Max for Live devices for integration with Ableton Live.

The flagship product line is the Compositor series, which began as an algorithmic techno generator in Max/MSP and has progressed through numerous iterations — including Compositor 4, Compositor v8 (a loop production studio oriented around radio-ether signal processing), and Compositor v9, described as a real-time embedded network operating system and audio middleware. Surrounding that line are additional tools such as SASER (a mobile audio application for macOS, iOS, and Android), the MDL12 sound processor, Compositor NTP for temporal coherence on mobile platforms, and the AjavaOS project.

The software sits at an unusual intersection of DSP research, embedded systems, and experimental music production, drawing on concepts like virtual radio ether simulation, spherical interaction networks, and quantized ULF transmission. The aesthetic leans toward noise, ambient drone, and dub-influenced techno, and the tools are typically aimed at producers and sound designers working in experimental and generative idioms. Yusipov also releases his own music made with these systems through Bandcamp.

Compositor Software has 6 products cataloged on Equipboard, including Generator Plugins, Virtual Instrument, and Vocoder Plugins.
