Hi-hat cymbal sound generation apparatus, hi-hat cymbal sound generation method, and recording medium

A hi-hat cymbal sound generation method that generates a sound of hi-hat cymbals based on information on an operation to a top pad, which corresponds to a top cymbal, and a bottom pad, which corresponds to a bottom cymbal, the top pad and the bottom pad being attached to a hi-hat stand with a pedal,

• wherein a distance between the top pad and the bottom pad is changeable by an operation of the pedal,
• state information is information that indicates which of a predetermined number of states a state is, the state being determined by the distance between the top pad and the bottom pad,
• of the states, a state in which the top pad and the bottom pad are closest to each other is designated as a close state,
• data on a foot close sound that corresponds to a sound in the close state generated by the top cymbal and the bottom cymbal coming into contact with each other in response to an operation of the pedal, data on a foot open sound that corresponds to a sound in a state other than the close state generated by the top cymbal and the bottom cymbal coming into contact with each other in response to an operation of the pedal, and data on a predetermined number of hit sounds, which correspond to sounds generated by hitting in the states indicated by the state information are previously recorded in a recorder, and
• the method comprises:
• acquiring at least the state information and vibration information, which is information on a vibration of the top pad;
• a triggering of checking whether the vibration indicated by the vibration information falls within a predetermined range in which a sound generation procedure is to be started, and reading at least all the hit sounds from the recorder and starting sound generation procedures for the hit sounds when the triggering determines that the vibration falls within the range in which a sound generation procedure is to be started;
• and
• a sound volume controlling of generating an output signal by controlling a sound volume of each sound whose sound generation procedure is being performed based on the current state information and information on a change of the distance between the top pad and the bottom pad.
