About Score
ossia score is a sequencer for audio-visual artists that is used to build interactive shows. It schedules and sequences OSC, MIDI, DMX, sound, and video across multiple software and hardware tools. Users can write interactive and intermedia scores, and scripts or live code in JavaScript, ISF Shaders, Faust, PureData, or C++.
The project connects to IoT protocols such as CoAP and MQTT, and to input devices including joysticks, Wiimotes, Leap Motion, BLE sensors, and LSL-compatible devices. It can load many audio and video formats, process visuals through Spout, Syphon, NDI, Shmdata, or Sh4lt, and sonify large datasets from CSV or HDF5 files. The homepage states that it runs on desktop, mobile, web, and embedded systems, down to the Raspberry Pi Zero 2. The repository page describes it as free and open source. Pricing is not stated.
