ABSTRACT:
An automatic musical performance apparatus for an electronic musical instrument provides a buffer memory and a recording medium. The automatic musical performance apparatus further includes a microcomputer for executing programs for read-out and write-in operations of the buffer memory and the recording medium. The musical performance data groups generated by the electronic musical instrument are temporarily stored in the buffer memory and are transferred to the recording medium wherein the musical performance data are recorded thereon. At this time, the microcomputer detects transfer control information corresponding to a data quantity which indicates the data quantity transferred in a unit time. This transfer control information is recorded at a predetermined area of the recording medium. Next, first musical performance data group of the data quantity is read from the recording medium and is stored in the buffer memory before the musical performance data groups are reproduced. Thereafter, remaining musical performance data groups other than the first musical performance data group are sequentially stored in the buffer memory as the previously stored musical performance data groups are read from the buffer memory and are reproduced.
