ossia score is a sequencer for audio-visual artists, designed to create interactive and intermedia shows.

Sequence various kinds of media in an intelligent timeline:

• Playback most audio formats, with support for multichannel
• H.264 and HAP video playback, with a state-of-the art cross-platform video & shader pipeline
• Send & receive OSC, MIDI, DMX or directly talk through HTTP or a serial port

A sequencer built for interactive shows:

• Trigger any part of the score upon external conditions or hardware controls
• Use conditions to create branching scores visually
• Control and get controlled through any external devices and protocols with a streamlined user interface

Multiple programming languages are embedded in ossia score:

• Livecode with JavaScript directly in the score for advanced mappings, or create device mapping scripts
• Use ISF shaders to create neat visuals
• Write simple math expressions for quick control
