ABSTRACT:
In performance data storing tracks, there are stored, in a mixed condition, actual performance data including pairs of pitch data designating a pitch of a tone to be performed and volume data of audible level designating a volume of the tone and fake performance data including pairs of pitch data designating a pitch of a predetermined performance tone and tone volume controlling data of non-audible level and fake performance data including pairs of pitch data designating a pitch of a predetermined performance tone and volume controlling data of non-audible level. Besides, the fake performance data for the predetermined performance tone is stored so as to be read out in advance of the actual data for the performance tone. The read-out fake performance data can be identified from the non-audible level of its volume designating data. In response to the fake performance data, a predetermined preliminary indication is made for preannouncing a key or other performance operating member to be operated. In generating automatic performance tones in response to the data from the tracks, only performance tones based on the actual performance data are actually sounded with no interference by tones based on the fake performance data, because the volume of the fake performance data is at the non-audible level. Thus, without requiring any extra control, the fake performance data can be used for the guiding purposes, causing no interference in automatic performance.
