PROBLEM TO BE SOLVED: To provide a karaoke device in which the maintenance of programs is made easier. SOLUTION: A control program (OS) is stored in a ROM cartridge 14 and application programs such as a sequence program are stored in an incorporated ROM 11 and a hard disk storage device(HDD) 15. Moreover, a file list is stored to specify which application program is started by the control program when the electric power supply is turned on. If the power supply is turned on, the control program is executed based on the file list and the application program is started. If an application program, which is not stored in the ROM 11 and the HDD 15, is specified, the program is down loaded from a host station and then, the device is started. |
