    摘要: A resonance signal generating method includes generating a first resonance signal of a first pitch circulating through first loop processing by inputting a first excitation signal to the first loop processing including first delay that delays the signal by a time corresponding to the first pitch and first attenuation that attenuates the signal, the first pitch being a pitch having a resonance frequency of a predetermined speaking length of a piano, generating a second resonance signal of a second pitch circulating through second loop processing by inputting a second excitation signal to the second loop processing including second delay that delays the signal by a time corresponding to the second pitch and second attenuation that attenuates the signal, the second pitch not being a pitch having a resonance frequency of any of speaking lengths of the piano or a pitch of a harmonic thereof but being higher than the first pitch, and outputting the first resonance signal circulating through the first loop processing and the second resonance signal circulating through the second loop processing.

    摘要: A resonance tone generation apparatus 20 is applied to an electronic musical instrument DM having a tone generator for generating a musical tone signal indicative of a piano sound in accordance with a tone generation instruction signal having a key number n, and a plurality of output portions for externally outputting a musical tone signal. The resonance tone generation apparatus 20 has a plurality of resonance tone generation circuits 30(n) each of which is assigned a different key number n, retrieves a musical tone signal indicative of a musical sound of the piano, generates a musical tone signal indicative of a resonance tone imitating a tone of a string of the piano resonated by the musical sound of the piano indicated by the retrieved musical tone signal, and supplies the generated musical tone signal to the plurality of output portions. Each of the resonance tone generation circuits 30(n) has a resonance circuit 40(n) which has a plurality of resonance frequencies corresponding to the assigned key number n, and generates a musical tone signal indicative of the resonance tone imitating the tone of the string of the piano resonated by the musical sound of the piano indicated by the retrieved musical tone signal, and a panning setting circuit 50(n) which generates a plurality of musical tone signals which are to be supplied to the plurality of output portions, respectively, and each of which indicates a different resonance tone in which a tone volume of the resonance tone indicated by the musical tone signal generated by the resonance circuit 40(n) is changed in accordance with the assigned key number, and supplies the generated musical tone signals to the plurality of output portions, respectively.

    摘要: A resonance tone generation apparatus 20 is applied to an electronic musical instrument DM having a tone generator for generating, in accordance with a tone generation instruction signal having a key number n, a musical tone signal indicative of a piano sound having a key tone pitch specified by the key number. In the resonance tone generation apparatus 20, the key numbers n are assigned. The resonance tone generation apparatus 20 has a plurality of resonance tone generation circuits 30(n) each being configured to have a plurality of resonance frequencies and each retrieving a musical tone signal indicative of a musical sound of the piano and generating a musical tone signal indicative of a resonance tone which imitates a sound of strings of the piano, the sound being resonated by the piano sound indicated by the retrieved musical tone signal. The resonance tone generation apparatus 20 also has a resonance circuit setting portion 60 which allows respective resonance frequencies of the resonance tone generation circuit 30(n) to coincide with frequencies of a fundamental tone and overtones of a musical sound PS(n) generated by the tone generator in accordance with tone generation instruction information including the key number n.
