摘要： A keyboard unit includes a planar member, a frame, a key, a hammer assembly, and a stopper. The frame is supported by and attached to the planar member. The key is connected to the frame. The hammer assembly is rotationally movably mounted to the frame. The stopper is configured to restrict a rotational and downward movement of the hammer assembly. The stopper is softer in hardness than the frame. At least part of the stopper is disposed below an upper surface of the planar member.

摘要： In an embodiment, the reed 10 includes a base part 150 and a vamp 153. The base part 150 has a planar portion 151 and a heel 157 at a first end of the base part 150. The vamp 153 extends from a second end of the base part 150, opposite the heel 157. The vamp 153 includes a sloping shape ending in a tip 100 which is inclined relative to the planar portion 151 when the vamp 153 is viewed from the planar portion 151.

摘要： A sound processing method includes: generating with a trained generative model, for each of a plurality of time points including a first time point, a first acoustic feature amount of a target sound to be generated, by sequentially processing input data including condition data representing conditions of the target sound; generating, for each of the plurality of time points, a time-domain waveform signal representing a waveform of the target sound based on the first acoustic feature amount; and generating, for each of the plurality of time points, a second acoustic feature amount based on the time-domain waveform signal. The input data at the first time point includes the second acoustic feature amount generated before the first time point.

摘要： An audio signal processing method includes obtaining, performing, and outputting. The step of obtaining includes obtaining localization control information that determines an acoustic image localization position of an own terminal in an audio signal processing system. The step of performing includes performing localization processing on the audio signal of the own terminal, based on the obtained localization control information. The step of outputting includes outputting the audio signal on which the localization processing has been performed.

摘要： 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, in accordance with determination whether a key corresponding to a pitch of event data is drivable by the keyboard driver, sound is generated based on a first sound-generating process in which the keyboard driver is configured to drive the key corresponding to the pitch or a second sound-generating process that is different from the first sound-generating process.
