ossia

ossia is a small, open-source collective that caters to artists, designers and educators who need to choreograph sound, video, lighting, sensors and robotics within a single timeline. Its flagship product, score, is an interactive sequencer built for “intermedia” performances and installations: a timeline where every lane can hold MIDI, OSC, DMX, audio, video clips or JavaScript logic, then fire those events in perfect sync or react to live input from cameras, touch screens or IoT devices. Typical use cases range from museum multimedia shows and VJ sets to university research labs that prototype spatial audio or networked lighting rigs. Because the engine is modular, users can extend it with Max/MSP-style boxes, PureData patches, C++ plug-ins or GLSL shaders, then share templates with the community. Projects can run standalone on Windows, macOS or Linux, or be baked into a headless runtime for Raspberry Pi and embedded boards. The same file authored in rehearsal can therefore travel from a laptop to a gallery wall without conversion. ossia score is available for free on get.nero.com; the site supplies the latest build through trusted Windows package sources such as winget, supports batch installation alongside other creative tools, and always delivers the most recent upstream release.
