<P>PROBLEM TO BE SOLVED: To improve a creation efficiency when creating reproduction control information to be added to music data such as audio data and performance data. <P>SOLUTION: A music playback device for reproducing audio data such as a CD reproduces music in a processing section, and displays, on the other hand, an audio signal waveform AW in the processing section on a display panel of a display part. While listening to the reproduced music, beat positions are inputted in real time by tapping or the like. A beat time at each beat position relating to the input is decided based on the audio data, and is stored as the reproduction control information. Beat position lines L<SB>1</SB>-L<SB>4</SB>are displayed based on the beat time relating to the decision, and a revised position of the beat position line L<SB>4</SB>is instructed by mouse operation or the like. A beat time relating to the storage is revised correspondingly to the revised position, and a new beat position line La corresponding to the beat time relating to the revision is displayed. The reproduction control information can be utilized when reproducing music based on the detection signal outputted from an operation sensor according to gesture by hand(s). <P>COPYRIGHT: (C)2004,JPO |
