CURRENT DIRECTIONS WITH MUSICAL PLUS ONE

We discuss the varieties of musical accompaniment systems and place our past efforts in this context. We present several new aspects of our ongoing work in this area. The basic system is presented in terms of the tasks of score following, modeling of musical timing, and the computational issues of the actual implementation. We describe some improvements in the probabilistic modeling of the audio data, as well as some ideas for more sophisticated modeling of musical timing. We present a set of recent pieces for live player and computer controlled pianos, written specifically for our accompaniment system. Our presentation will include a live demonstration of this work.
