The Continuator is the name of a research project conducted by Francois Pachet at Sony Computer Science Laboratory in Paris. It is an experiment focusing on the interaction in real time with a system that is able to distinguish and store different musical styles. These features make the interaction between a musician and The Continuator a sort of dialogue, because the system is able to produce musical phrases as they accord perfectly with the style of music chosen by the musician and propose, therefore, as a real continuation of the incipit sound stored. Another important feature of The Continuator is its ability to accumulate experience from each interaction, this means that the dialogue becomes increasingly attractive as the system learns about the expressive style of the musician with which it interacts. Just the ability to learn The Communicator distinguished from many other interactive musical systems that have been developed in recent years. From the point of view of the architecture it is possible to identify two modules: the first (dedicated to the analysis) receives input from a MIDI interface, and the second (dedicated to the generation of sounds) can operate in continuous mode (in this case the system, receives input, produces noises incessantly), or in a "question and answer" (for each input follows a single sound output). The experiments performed with The Continuator have focused on musicians 'avant-garde' (Lubat Bernard, Claude Barthélémy, György Kurtag, etc..) And children, for the latter, the system has proved formidable in developing listening skills that is extremely rare in preschool.
