Ossia Score is an open-source sequencer designed for audio-visual artists to create interactive shows. It allows sequencing OSC, MIDI, DMX, sound, video, and more across multiple software and hardware. Create interactive intermedia scores, scripting and live-coding with JavaScript, ISF Shaders, Faust, PureData, or C++. Interact with joysticks, Wiimotes, Leap Motions, web APIs, and BLE sensors. Process visuals via Spout, Syphon, NDI, Shmdata, or Sh4lt; and sonify datasets with CSV and HDF5 support. Free, open-source, and runs on desktop, mobile, web, and embedded systems (even Raspberry Pi Zero 2).
