Abstract
A sound signal generation method for a keyboard including a pedal and a key, the method according to an embodiment of the present disclosure comprises generating a first sound signal and a second sound signal different from the first sound signal based on first operation data corresponding to an operation of the key, and adjusting a 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 to control a decay rate of the first sound signal to be different from a decay rate of the second sound signal based on a key release operation of the key.
Claims16
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.
