Claims (1)

[Scope of Utility Model Registration Claim] In an electronic musical instrument with a delay vibrato effect that applies vibrato to a musical sound generated a predetermined time after a key is pressed, delay vibrato is applied only to the first key press;
a specifying means for selectively specifying whether to apply vibrato from the time the key is pressed when the previously pressed key is not released, or to apply delay vibrato every time even when the key is repeatedly pressed; An electronic musical instrument with a delay vibrato effect, comprising: a detection means for detecting a designated state of the designation means; and a control means for controlling application of delay vibrato to the generated musical tone based on a detection result by the detection means.
