Abstract
In an automatic performance device which automatically performs a piece of music composed of note information input externally, note information input on a real time basis is corrected on the basis of beat information of a piece of music input thereafter and the resulting note information is stored. Correction information for converting the corrected note information into the originally input uncorrected note information is also stored for each note information. When the piece of music is performed automatically, a tone is generated on the basis of the corrected note information and the correcting information, but when the piece of music is output as a score, output is made on the basis of the corrected note information. Alternatively, for note information input by a step time inputting process, information is stored on a timing at which each note input thereafter is generated. When the piece of music is performed automatically, a tone is generated on the basis of the note information the generation timing of which is corrected on the basis of the information on the timing of generation of that note, while a score is output, the input note information is used as is. As a result, accurate score output is possible with note information input in the real time inputting process, and an automatic performance that is natural and rich in musicality is achieved with note information input by the step time inputting process.
