ABSTRACT:
An electronic musical apparatus is constructed to play an automatic performance and a manual performance during progression of a musical composition. A data memory is provided for storing a sequence of automatic performance data representative of the musical composition which is composed of a plurality of parts and which is divided into a series of passages by musically rational manner, and for storing a sequence of check point data indicative of break points of the passages. An input implement is manually operated for inputting a sequence of manual performance data assigned to a particular part of the musical composition. A tone generator receives the inputted manual performance data for sounding the manual performance. A microprocessor sequentially retrieves the automatic performance data and the check point data from the data memory and for feeding the retrieved automatic performance data to the tone generator so as to enable the same to sound the automatic performance. The microprocessor further operates when the manual performance data is continuously inputted for controlling the tone generator to mute the particular part of the automatic performance while allowing the sounding of the same particular part of the manual performance. The microprocessor processes the retrieved check point data for checking when the musical composition during the progression thereof reaches each break point and for controlling the tone generator to release the muting of the particular part of the automatic performance timely at a desired break point so that a complete passage of the automatic performance can be restored for the particular part.
