PURPOSE:To detect the completion simultaneously with a sending sound source is completed by comparing an end address of an accumulated sound source with an address at the time of reading the data from a sound source accumulating memory at the time of reading the contents of a digitized sound source and sending the result to a digital line. CONSTITUTION:At the time of starting, a sound sending instruction from the external part is sent to a sound source sending control part 1 by a starting signal 104, the signal of an address bus 101 is successively counted up by the sound source sending control part 1 and the digital data of the sound source are received from a sound source accumulating memory 2 through a data bus 100 to the sound source sending control part 1. Received digital data are processed by a sound source sending control part 1 and sent to a digital line 103. On the other hand, a comparing part 32 compares the address information on the address bus 101 and the set value on a sound source end address setting part 31. When both are coincident, the completion is informed to the sound source sending control part 1 by the coincident signal sent from a comparing device 32 to an end detecting signal line 102.
