ABSTRACT:
An automatic performance device has a RAM for storing automatic performance information formed of time information and performance information containing time change information. A CPU instructs updating of an automatic performance position within the automatic performance information measure by measure. In response to the instruction, searching is made of the head location of a desired measure in the automatic performance information, by reading out the performance information of the automatic performance information from the RAM, based on the time information, and counting time corresponding to each measure in the performance information read out to obtain a count value of the time. The reading-out is continued until the head location of the desired measure is searched out. When the time change information is read out during the searching, the count value of the time corresponding to one measure in which the time change information is read out, is corrected, based on the time change information.
