Patent ID: 7476797

Claim:
A resonance generator comprising: normal sound generating means for generating a normal sound in response to a sounding instruction; first resonance generating means for generating first resonance; second resonance generating means for generating second resonance; switching means for selecting the first resonance generating means when a damper operator is operated when the sounding instruction is inputted, and selecting the second resonance generating means when the damper operator is not operated when the sounding instruction is inputted; level control means for controlling levels of the first resonance and the second resonance according to an operation depth of the damper operator; and resonance mixing means for adding the normal sound and either resonance selected of the first resonance or the second resonance by the switching means, wherein the first resonance is resonance when the damper operator is operated before inputting of the sounding instruction, and the second resonance is resonance when the damper operator is operated after inputting of the sounding instruction.
