Abstract
An electronic musical instrument for causing a tone generator to generate a musical tone corresponding to a musical performance while controlling an envelope by operation of a pedal. An operated-amount signal generator is provided for detecting an operated amount of the pedal and for generating an operated-amount signal, and an effect adding unit is provided for controlling parameters for effect addition so as to add an effect to a musical tone generated from the musical tone generator in accordance with the operated-amount signal from the operated-amount signal generator. The operated-amount signal from the operated-amount signal generator is changed by the operation of the pedal, and an effect-adding parameter in the effect adding unit is changed accordingly, to thereby add an effect to the generated musical tone.
