摘要 PCT No. PCT/JP91/00085 Sec. 371 Date Sep. 2, 1991 Sec. 102(e) Date Sep. 2, 1991 PCT Filed Jan. 25, 1991 PCT Pub. No. WO91/11811 PCT Pub. Date Aug. 8, 1991.A digital sound source apparatus includes a semiconductor memory connected to a central processing unit. The memory has a quantized data storage area and a program data storage area. A quantized data train and a stop code are stored in a series of addresses in the quantized data storage area, a start address is set in a certain address in the program data storage area. When the start address is read from the program data storage area, the quantized data are sequentially read from the quantized data storage area and are sequentially loaded into a data register. When the stop code is read from the quantized data storage area, loading of the data into the data register is inhibited by a read/write control circuit, the quantized data loaded into the data register are converted into an analog sound signal by a D/A conversion circuit.
