PURPOSE:To efficiently process the operations of iteration and jump by providing a means of reading out music sheet information from a memory device and automatically playing according to said music sheet information. CONSTITUTION:When a presettable counter 222 counts the length of one note, it outputs a carry output. This carry output is connected to the clock input of an address counter 216. Hence, the assigned address of a memory device 212 advances by 1. The carry output is applied to the set input of the presettable counter 222 and when the carry signal is produced in this way, the address of the memory device 212 advances by 1 and the note information following the note having been played thus far is outputted in its output and the sound length information of the terminal (h) out of these is set. |
