Claim Text:
1. A resonance tone generation apparatus applied to an electronic musical instrument having a tone generator which generates a musical tone signal indicative of a musical sound which has a tone pitch specified by a tone pitch number and is generated by a polyphonic musical instrument by vibrating a vibrating body corresponding to the tone pitch number, in accordance with a tone generation instruction signal including the tone pitch number, and a plurality of output portions for outputting a musical tone signal, the resonance tone generation apparatus comprising: a plurality of resonance tone generation portions each of which is assigned a different tone pitch number of the electronic musical instrument, retrieves a musical tone signal indicative of a musical sound of the polyphonic musical instrument, generates a musical tone signal indicative of a resonance tone imitating a tone of the vibrating body of the polyphonic musical instrument resonated by the musical sound of the polyphonic musical instrument indicated by the retrieved musical tone signal, and supplies the generated musical tone signal to the plurality of output portions; each of the plurality of resonance tone generation portions including: a resonance portion having a plurality of resonance frequencies corresponding to the assigned tone pitch number, and generating a musical tone signal indicative of a resonance tone which imitates a tone of the corresponding vibrating body of the polyphonic musical instrument resonated by the musical sound of the polyphonic musical instrument indicated by the retrieved musical tone signal; and a panning setting portion for generating a plurality of musical tone signals which are to be supplied to the plurality of output portions, respectively, and each of which indicates a resonance tone in which a tone volume of the resonance tone indicated by the musical tone signal generated by the resonance portion is changed in accordance with the assigned tone pitch number, and outputting the generated musical tone signals to the plurality of output portions, respectively.
