Ricochet: a real-time choreographic engine for spatial music

Ricochet is a macOS application for composing and performing the movement of sound in space. It generates the behaviour of up to thousands of points, their positions and amplitudes, on a modular canvas using generators, modifiers, patterners, and mergers. Ricochet transmits the result as Open Sound Control over UDP to spatialisation environments. Native support is included for IRCAM Spat5, IEM plug-ins, ICST Ambisonics, ADM-OSC, and a plain documented dialect, so it pairs with Max/MSP, Reaper, and any OSC-capable renderer. Performance controls include scene morphing, macro banks, MIDI learn (including 14 bit controllers), and OSC input for sensors and trackers. Five demonstration patches are bundled. Universal binary for Apple Silicon and Intel, macOS 11 or later. Released under the MIT licence.
