Abstract
A synchronous player system is used for recording an ensemble between an automatic player piano and an audio player and playback therebetween; while a user is playing on the automatic player piano in ensemble with the audio player, reference characteristic data of the performance is extracted from the audio music data, and are stored in a memory together with the event codes; when the user instructs the synchronous player system to reproduce the performance in ensemble with the same piece of music recorded in another compact disc, the synchronous player system extracts objective characteristic data from the audio data recorded in the other compact disc, finds differences through a correlation analysis, by way of example, and rescheduling the timing to reproduce the note events for synchronously controlling the automatic player piano and audio player.
