Abstract

PURPOSE:To increase the rhythmical sense of a melody and eliminate the unnatural beat of the melody by making a melody memory store the content of strength of a sound as sound-pressure data. CONSTITUTION:A reference signal for time-counting is generated by an oscillator 11 and the frequency of the signal is divided by a frequency divider 12 so as for the signal to be a signal for time-counting, while this divided-frequency signal is counted by a counter 14 for time. Moreover, the note information of the sound of melody is stored in the memory 19 and a reference signal for scale is subjected to variable frequency divider 22 corresponding to the content of a sound height expressed by the note information and is supplied to a melody-sound controlling circuit 23. The circuit 23 supplies a speaker 24 with the sound height signal designated for the strength based on these signals.
