ABSTRACT:
An electronic musical instrument includes a keyboard, a first tone generator, a second tone generator, a hold switch, and a control unit. The keyboard designates a pitch of a musical tone to be generated. The first tone generator generates a first musical tone signal corresponding to the pitch designated by the keyboard. The second tone generator generates a second musical tone signal corresponding to the pitch designated by the keyboard. The hold switch generates a pitch hold command. When the pitch hold command is generated, the control unit inhibits a pitch change in the second musical tone signal generated by the second tone generator to hold a predetermined pitch.
