Abstract
PURPOSE:To reduce the data amount to be stored, by storing an sound volume changing rate data to a memory as a sound volume control data, in an automatic player which sequentially reads out a score data stored in the memory and plays music sound. CONSTITUTION:A data of a part of recording medium 12a of a musical note 12 is read in 10 and stored in a memory 14 for sequential readout. The mark of upper rank bit of the data judges and detects 44, 60... sound data or code length data. At first, when the initial sound data is detected 36, it is latched to a latch 38 of a sound control signal forming circuit 25. Thereafter, when a sound charning rate data is detected 52, it is latched to a latch 28. With each tempo-clock 54, the content X of the latch 38 and the content Y of the latch 28 are operated (X+X.Y) to be new content to the latch 38. The content of the latch 38 is in DA conversion 56 to be a sound control signal VC1.
