Claims

[Scope of utility model registration request]

(1) A timbre specifying means for specifying a desired timbre from among a plurality of preset tones, and an envelope for imparting envelope information preselected by the timbre specified by the timbre specifying means. An electronic musical instrument having an information adding means includes an envelope information changing means for changing the preselected envelope information to other envelope information, and it is possible to add different envelope information to one tone. Characteristic electronic musical instruments.

(2) The other envelope information is obtained by changing the attack time of the preselected envelope information.
An electronic musical instrument listed on the tomb.

(3) Each of the plurality of tones is obtained by synthesizing two or more musical sound waveforms, and the other enlope information differs in attack time for the two or more musical sound waveforms. An electronic musical instrument according to claim 1 of the utility model registration claim, characterized in that:
