ossia score is a free, open-source interactive sequencer designed for audiovisual performances, installations, and experimental media production. It provides a timeline-based environment for coordinating audio, video, lighting, and external devices. Users can sequence MIDI, OSC, DMX, and other control messages alongside multimedia content. The software supports interactive compositions that respond to sensors, controllers, and network events. Its visual programming tools integrate JavaScript, Faust, Pure Data, shaders, and C++ processing. Artists can create generative visuals, manipulate three-dimensional geometry, and process audio in real time. It also supports audiovisual routing through NDI, Spout, Syphon, and other protocols. Available across desktop and embedded platforms, ossia score enables complex multimedia installations and live performances.
