Abstract

According to which a damper is operated before or after keying, one of two resonances is generated. A second waveform storage 18 storing original waveform data of a first resonance based on a music sound including an impact sound of keying according to a before-key-pressing pedaling, and a third waveform storage 19 storing original waveform data of a second resonance based on a music sound which does not include an impact sound of keying according to an after-key-pressing pedaling, are provided. A switch 20 is switched according to the state of the pedal at the time of key pressing to supply selected resonance waveform data to a resonance generating unit 16. The resonance signal outputted from the resonance generating unit 16 and a music sound signal of a direct sound of keying are added by an adder 24 and inputted into a sound system.

Dependent claims

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.
