PURPOSE:To feed a music selection program in a short time and furthermore to reduce the increment of the capacity of a memory, by adding five keys, i.e., an AND key, a TO key, a repeat key, a WITHOUT key and an index ky in addition to ten-key as program keys. CONSTITUTION:A program key input device 1 and a program play start command means 2 are stored in a keyboard 10. At the same time, a concentrated array is formed among ten-key 11, an AND key 12, a TO key 13, a repeat key 14, a WITHOUT key 15, an index key 16 and a start key 17. A 1-chip microcomputer 20 contains a CPU, an ROM, an RAM, an input/output device, etc. within a 1-chip LSI. The inputs given by the program keys 11-16 mean the writing of a music selection program to the RAM serving as a memory of the computer 20. When the key 17 is turned on, the music selected previously by the program keys is played. |
