PROBLEM TO BE SOLVED: To add different vibrato by partial sounds by adding pieces of vibrato information to sound signals and putting them together. SOLUTION: Respective partial sounds are assigned to time-division channels, vibrator data are selected by the partial sounds, and the level of the vibrato is also specified. According to musical factors such as tone number data TN or the like, the vibrato data on the respective partial sounds are selected by a vibrato data memory through a vibrato ROM 23 and on the basis of the vibrato level data SL, multipliers 55A to 55C control the level of the vibrato. Further, filter characteristic FCs 1 to FC4 for the vibrato data on the partial sounds and respective digital filters 51A to 51D to which the data are inputted are selected through the vibrato ROM 23 according to the musical factors such as the tone number data TN. |
