Abstract
Prestored melody data is read out as the performance of the melody progresses. When event data contained in the read melody data represents a key to be depressed for a melody performance, the key represented by the event data is indicated to a performer. When the performer does not depress the key even when a timing when the key is to be depressed has passed, reading the melody data is stopped until the key is depressed. When the performer depresses the key before the timing when the key is to be depressed, relevant event contained in the melody data to be read out in a time period between the time when the key was actuated and the time when the timing at which the key is to be depressed comes is rapidly read out. When the event data rapidly read out contains volume control event data, the processing of the event data is changed such that the volume of the musical sound to be produced is minimized.
