Abstract: To provide a change of sound in response to a player's operation that is close to the change of sound of real hi-hat cymbals. A hi-hat cymbal sound generation apparatus according to the present invention includes an input part, a recording part, a trigger part and a sound volume control part. The input part acquires state information and vibration information. The recording part records data on a foot close sound, data on a foot open sound, and data on a hit sound in each state indicated by the state information. The trigger part checks whether the vibration indicated by the vibration information falls within a predetermined range in which a sound generation procedure is to be started, and starts sound generation procedures for at least all the hit sounds when the trigger part determines that the vibration falls within the range in which a sound generation procedure is to be started.

Abstract: A hi-hat cymbal sound generation apparatus according to the present invention includes an input part, a recording part, a trigger part and a sound volume control part. The input part acquires distance information on a distance between a top pad and a bottom pad, state information and vibration information on a vibration of the top pad. The input part acquires the state information by determining the state information based on a corrected distance, which is obtained by adding a distance correction value, which corresponds to a magnitude of the vibration indicated by the vibration information, to the distance indicated by the distance information. The recording part records data on a hit sound in each state indicated by the state information. The trigger part checks whether the vibration indicated by the vibration information falls within a predetermined range in which a sound generation procedure is to be started.
