Abstract
An electronic musical instrument changes sound effects, such as resonance and reverberation, during a performance. The instrument has a tone-ON channel counter, for counting keys that are simultaneously depressed; an output channel determination unit, for determining an output channel in consonance with a count value held by the tone-ON channel counter; and an output channel selector, for designating the output channel, so as to provide a desired sound effect through the selected output channel. In a modification, the instrument has a parameter value determination unit, for determining a parameter value in consonance with a count value counted by the tone-ON channel counter; a resonant tone production unit, for adding a desired sound effect; and a controller, for employing the parameter value to control the resonant tone production unit. In a further modification, the instrument has an effect addition unit, for adding sound effects in consonance with a parameter value designated by the parameter value determination unit and the resonant tone production unit.
