A musical sound generation device includes a control device which, when a performance operator among a plurality of performance operators has been operated for a part that has been set to sound a predetermined number of simulated voices of an analog synthesizer, assigns a sounding parameter of one or two or more voices, which form a timbre of a simulated voice of the analog synthesizer corresponding to the operated performance operator and are selected from a plurality of sounding voices, to a sound generation circuit, and assigns, to the sound generation circuit, an information set selected from a plurality of information sets and each include a variation value that applies a variation to the sounding parameter of the one or two or more voices, and a sound generation circuit that performs a sounding process of the one or two or more voices using the sounding parameter and the information set.

Musical sound generation method, musical sound generation device, and recording medium

When the on-on time between Noteand Noteis shorter than the double stop judgment time JT, as shown in FIG.A, the mode is changed from Unisonto Unison. When note-on information of Noteis inputted at time t, the parts-are assigned to Note, and simultaneously start sound generation at pitch n, as shown in FIG.B. Next, when note-on information of Noteat pitch nlower than Noteis inputted at time t, the mode is switched to Unison. Part(with the timbre being trumpet) and Part(with the timbre being clarinet) which are higher in the pitch order are assigned to Note, and continue generating the musical sound at pitch nof Note, and Part(with the timbre being alto saxophone) and Part(with the timbre being trombone) which are lower in the pitch order are assigned to Note, stop the sound generation at pitch n, and start sound generation at pitch nof Note
