Abstract
A string signal generator generates a string signal representing vibration of a string corresponding to a specified pitch in response to a note-on instruction such that the string signal rises and then attenuates in response to a note-off instruction. The string signal generator distributes the generated string signal to a plurality of loop circuits of a string resonance simulator. The plurality of the loop circuits correspond to a plurality of pitches and circulate resonant signals of the corresponding pitches, each loop circuit having a delay element for delaying the resonant signal by a time depending on the corresponding pitch, and an attenuation element for variably attenuating the resonant signal according to an attenuation coefficient. A controller respectively provides attenuation coefficients to the attenuation elements in the plurality of the loop circuits based on the note-on instruction, the note-off instruction, a damper-pedal-on instruction, and a damper-pedal-off instruction.
