Electronic musical instrument with simplified operation for setting numerous tone parameters

A parameter setting apparatus for an electronic musical instrument for independently setting a plurality of parameter values, for controlling tones, comprising:

• a plurality of parameters value setting means, arranged on an operation panel, each corresponding to one of said plurality of parameters, each of said plurality of parameter value setting means including an incrementing operation member for incrementing the corresponding parameter value, a decrementing operation member for decrementing the corresponding parameter value, and a preset operation member for setting the corresponding parameter value to a corresponding preset value;
• increment/decrement means for incrementing or decrementing each corresponding parameter value when said corresponding incrementing operation member or said corresponding decrementing operation member is operated, respectively;
• preset value setting means for independently setting the corresponding parameter value to the corresponding preset value when said corresponding preset operation member is operated;
• and
• a tone generator for generating a musical tone signal based on the plurality of parameter values;
• parameter memory means for storing the plurality of parameter values supplied to said tone generator;
• initial value memory means for storing initial values of the plurality of parameters;
• means for transferring the parameter initial values to said preset value setting means and said parameter memory means upon a power-ON operation;
• preset values supplier means for transferring the corresponding preset value set in said preset value setting means to said parameter memory means when said corresponding preset operation member is operated;
• preset value renewal means for incrementing of decrementing the corresponding parameter value in said preset value setting means upon operation of said corresponding incrementing or decrementing operation member, respectively;
• and
• parameter value increment/decrement means for incrementing or decrementing the corresponding parameter value in said parameter memory means upon operation of said corresponding incrementing or decrementing operation member, respectively.
