Our goal is to avoid this laborious training phase and develop a system that adapts to the musician currently playing without any training. [...] we first convert (a MIDI version of) the given score into a sound file, by using any available software synthesizer. [...] In the live tracking process, the incoming audio stream must be aligned, on-line, to the synthesized audio file. [...] The algorithm to be described here builds on a dynamic programming method first presented by S. Dixon [...]. Robustness against changes in tempo and timing [...] Robustness in the face of structural changes [...] the musician may choose to follow structural indications in the score (specifically, repeats), but may also decide to ignore repeated sections. [...] Error tolerance [...] In both tests the system worked very reliably, even in the presence of errors (and even some re-starts) by the pianist.
