ossia score overview

ossia score is a cross-platform intermedia sequencer for precise and flexible scripting of interactive scenarios.
Control and score any OSC-compliant software or hardware: Max/MSP, PureData, openFrameworks, Processing…

An intermedia sequencer

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

Advanced interaction facilities

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

A scriptable, open software

Multiple programming languages are embedded in ossia score:

Livecode with JavaScript directly in the score for advanced mappings, or create device mapping scripts
Create blazing fast audio processors with Faust
Extend any part of the software through the C++ API
Write simple math expressions for quick control

Mixed modular & timeline workflow

Connect processes in a modular way directly from its timeline:

Switch between timeline and nodal view at any point to edit processes more precisely
Create state-machine-like scores for atemporal scenarios
Nest and group without depth limit

What’s new in version 3.1.3

Updated on Oct 04 2022

New features:

[JS] Add a compute method for off-exec-thread computations ; add a layoutTextLines operation which allows to break a text so that it fits a rect (roughly!)
[Search] WIP on searching addresses within processes and ports in the search text box
[Expressions] Add a 'contains' operator to check whether an array contains a value, or a string contains a substring

Bugfixes:

[avnd] Fix midi scroller bugs
[Scenario] Fix some drag and drop cases (dropping .layer files was broken)
[gfx] Add missing headers for make install (should fix some issues with building templates / addons / jit stuff)
[lv2] Fix memory leak in C API (yay) for ui detection
[gfx] Fix that some shader pairs would fail at linking for isf. This makes a lot more shaders work
[Search] Optimize searching for addresses in state
[Search] Fix that search idget does not do anything in debug mode
[UI] Fix that the ports would sometimes not show up at the right place
[Camera] Set mode to stretch until we add a way to configure it
