PURPOSE:To obtain a small-noise musical sound signal by the musical sound generation device of the electronic musical instrument which processes and generates musical sound data at a constant speed regardless of the interval of the musical sound, and mixes and outputs plural musical sounds differing in interval by making the maximum value of one sound of the mixed musical sound data, inputted to a DAC, as large as possible. CONSTITUTION:A music sound data generating means 110 generates plural musical sound data, and a musical sound data mixing means 120 mixes N sounds among the musical sound data and outputs the mixed musical sound data to the DAC 130, which converts the mixed musical sound data into an analog musical sound signal. At this time, when the maximum value of the input data to the DAC is denoted as C and the maximum value of each sound of the input data to the DAC is denoted as A, the data are so mixed that the product of A and N is larger than C, the mixed musical sound data overflows/underflows a little, and the maximum value A of each sound is made as large as possible. |
