Absolutely Free

Ossia Score overview

Ossia score enables precise and flexible scripting of interactive scenarios.

  • Control and score any OSC-compliant software or hardware:
  • Max/MSP, PureData, openFrameworks, Processing…
  • Multi-protocol sequencer

Remote-control various applications, such as Max/MSP, PureData, Processing, openFrameworks, Unity3D, modul8, Live… using OSC, OSCQuery, ArtNet and more to come.

Flexible time management

Set temporal & conditional relationships between events, interactively trigger them, hierarchize your score, and use loops to produce interactive scenarios.

Interpolation & breakpoint functions

Automatically interpolate parameters’ values between events or draw your own curved breakpoint function. Map addresses together, and live-script your score using JavaScript.

+ a creative coding library for easing the interoperability with score

In order to ease score‘s interoperability with 3rd-party environments and programming languages, we have published score‘s underlying framework: libossia, and published several implementations and bindings for a variety of contexts.
