PROBLEM TO BE SOLVED: To provide a KARAOKE sing-along machine which enables a singer to sing desired KARAOKE sing-along music without making double singing. SOLUTION: When an operator inputs the music number of the music to be played by operating an operation section 12, a CPU section 7 temporarily stores the music number data into a RAM 7b, adds reservation number data, time reservation data and playing completion data to the music number data and stores the data in a playing music information memory section 15. This CPU section 7 compares the music number data of the musical piece which cannot be registered for reservation to be stored in this playing music information memory section and the music number data of this musical piece. The CPU section registers this music if the music number data do not coincide with each other. If the data coincide, the CPU section generates an alarm sound or displays the alarm indicating this effect and rejects the registration. The CPU section 7 stores the music number data of the musical piece which cannot be registered for reservation in the playing music information memory section 15 by the user of the device who inputs this data together with a password by operating the operation section 12. The cancellation thereof is executed by the similar operation. |
