Abstract
An electronic musical instrument comprises a pitch designation device such as a keyboard, performance manipulators such as foot pedals, a tone color designation device such as tone color switches for designating a tone color, an effect designation device for selectively designating an effect as the effect assigned to at least one of the foot pedals on the basis of the selected tone color, and a tone generation control device for controlling the tone generation to be accompanied with the designated effect. That one pedal is assigned with a plurality of effects and a predetermined effect is automatically given correspondingly to the designation of the tone color of musical tone to be generated. For example, a sosenuto effect and a bright effect are selectively assigned correspondingly to the piano tone color and the non-piano tone color. Further, an intermediate output which increases continuously is generated when the pedal is pushed down. An output which changes multistageously step by step is generated on the basis of the intermediate output. At the time of the releasing of the pedal, a multistageous change is produced by a smaller value than that at the time of the pushing of the pedal.
