<P>PROBLEM TO BE SOLVED: To provide an electronic keyboard musical instrument capable of setting various kinds of musical parameters such as tone, without having to provide a special switch for changing modes. <P>SOLUTION: When a state (simultaneous key-depressed state) is detected where three keys of a right-end side included in a keyboard section 10 are depressed at the same time, a mode shifts to a setting mode that enables various settings, including tone setting of sounding. Meanwhile, when any key in the simultaneous key-depressed state is released, it returns to a normal performance mode for performing normal key depressing sounding. Since a required setting operation included tone setting is performed, by depressing keys in a keyboard section 10 in the setting mode, tone setting etc. is performed merely by key-depressing operation of the keyboard, special switch, such as the mode-changing switch, need not be installed. <P>COPYRIGHT: (C)2011,JPO&INPIT |
