Abstract
An electronic musical instrument is disclosed as including a tone pitch-assigning device which assigns pitches to musical tones which are to be generated by the instrument; a plurality of manually operable members; a control message-producing device that automatically produces musical tone-controlling messages which respectively correspond to operation of the manually operable members; and a musical tone-generating device which automatically generates a plurality of musical tones for each of the musical pitches assigned by the tone pitch-assigning device. The tone volumes of the musical tones are controlled based upon the tone-controlling messages so that the musical tone-generating device generates musical tones with tone volumes which may change in time, which may maintain a constant volume, or which may be attenuated, depending upon certain predetermined conditions.
