Abstract
A keyboard device includes a plurality of keys, and a keyboard driver configured to drive at least a part of the plurality of keys. The keyboard device is configured such that sound is generated based on a first sound-generating process in which the keyboard driver is configured to drive a key corresponding to a first pitch, upon receiving performance data including the first pitch. The keyboard device is configured such that sound is generated based on a second sound-generating process that is different from the first sound-generating process, upon receiving performance data including a second pitch that is different from the first pitch.
Claims11
A keyboard device comprising:
- a plurality of keys;
- and
- a keyboard driver configured to drive at least a part of the plurality of keys,
- the keyboard device being configured such that sound is generated based on a first sound-generating process in which the keyboard driver is configured to drive a first key corresponding to a first pitch, upon receiving performance data including the first pitch and upon determining that the first key corresponding to the first pitch is drivable by the keyboard driver, and
- the keyboard device being configured such that sound is generated based on a second sound-generating process that is different from the first sound-generating process, upon receiving performance data including a second pitch that is different from the first pitch and upon determining that a second key corresponding to the second pitch is not drivable by the keyboard driver.
A sound generation control method comprising:
- receiving performance data;
- generating sound based on a first sound-generating process by driving a first key corresponding to a first pitch, upon receiving the performance data including the first pitch and upon determining that the first key corresponding to the first pitch is drivable by a keyboard driver;
- and
- generating sound based on a second sound-generating process that is different from the first sound-generating process, upon receiving the performance data including a second pitch that is different from the first pitch and upon determining that a second key corresponding to the second pitch is not drivable by the keyboard driver.
A non-transitory computer readable medium storing a program causing a computer to execute a process, the process comprising:
- receiving performance data;
- generating sound based on a first sound-generating process by driving a first key corresponding to a first pitch, upon receiving the performance data including the first pitch and upon determining that the first key corresponding to the first pitch is drivable by a keyboard driver;
- and
- generating sound based on a second sound-generating process that is different from the first sound-generating process, upon receiving the performance data including a second pitch that is different from the first pitch and upon determining that a second key corresponding to the second pitch is not drivable by the keyboard driver.
