Claim 0:
1. A sound signal generation device for a keyboard including a pedal and a key, the sound signal generation device comprising:
at least one memory storing instructions; and
a processor that implements the instructions to:
generate a first sound signal and a second sound signal different from the first sound signal based on first operation data corresponding to a first operation of the key; and
adjust a relationship between the first sound signal and the second sound signal based on the first operation data to control a decay rate of the first sound signal to be different from a decay rate of the second sound signal based on second operation data corresponding to an operation on the pedal,

wherein the relationship includes a relationship between a timing of the sounding of the first signal and the second sound signal,
wherein the processor further adjusts the relationship between the first sound signal and the second sound signal to sound at respective timings according to a physical quantity of a key pressing operation of the key,
wherein the physical quantity includes an acceleration of the key,
wherein the timing of the sounding of the first sound signal is before the timing of the sounding of the second sound signal, in a state where the acceleration is relatively small, and
wherein the timing of the sounding of the first sound signal is later than the timing of the sounding of the second sound signal, in a state where the acceleration is relatively large.
