i-score is an intermedia sequencer dedicated to interactive scenario authoring. Designed as a generic data sequencer, this open source software allows a remote dialog with various applications, such as Max, Pd, Live ... using show-control protocols like OSC to store and recall parameters value.

Founded by the National French Research Agency project OSSIA, the 1.0 version of i-score proposes a graphical formalism to set precise temporal and conditional relationships between events that can be interactively triggered. The edition and the execution of several independant time layers offer an unique way to manage parameters automations being attended by tools to interpolate states or to draw your own curved breakpoint function.

As the result of continuous discussions between scientists, ingeneers and users, the presentation will be articulated around well known issues identified during the development of setups for show-control or interactives setups used in museographic situations.
