Interactive scores proposes a model to write and execute interactive multimedia scores. The software i-score implements the above model using Hierarchical Time Stream Petri Nets (HTSPN). However, this model is very static and modelling new features would require a complete redesign of the network or sometimes they cannot be expressed. Another problem of i-score is that it does not provide a good visual feedback of the execution of the scenario. In this work, we define and implement an interpreter of interactive scores using the synchronous programming language ReactiveML. Our work takes advantage of the expressiveness of the reactive model and the power of functional programming to develop an interpreter more dynamic and simple. Contrary to the Petri Net model, our approach allows to model precisely the hierarchical behaviour, and permits the easy prototyping of new features. We also propose a visualization system using the environment INScore that provides a real-time visualization of the execution of the score.
