楽器のビブラート装置。It has a first memory that stores frequency information of a musical tone and a second memory that stores a predetermined musical sound waveform, and performs a predetermined calculation repeatedly on the set value of the predetermined frequency information read from the first memory. When the result data reaches a predetermined attainment value, a read clock is applied to the second memory, and waveform data for one step of the musical sound waveform is read from the second memory to generate and emit the musical sound. and a means for making the value of the predetermined attained value variable, and by changing the value of the predetermined attained value by the variable means, the generation cycle of the read clock is changed, and a vibrato effect is added to the generated musical tone. Features a vibrato device for electronic musical instruments.
