Abstract
Provided is a sound source control information generating apparatus, adapted for performing slapping techniques. According to the present invention, information based on an output value of a first sensor that detects striking on the housing is stored in a memory means. If striking on the struck head of a percussion instrument is detected based on an output value of a second sensor that detects striking on the struck head, whether an output value equal to or greater than a predetermined value is obtained from the first sensor in a predetermined time interval before a timing of detecting the striking on the struck head is determined based on the information stored in the memory means.
Claims16
A sound source control information generating apparatus, adapted for generating sound source control information which controls a sound source means that generates a musical sound based on striking on a struck head of a percussion instrument that comprises a housing and the struck head, and the sound source control information generating apparatus comprising:
- a first acquisition means obtaining an output value of a first sensor that detects striking on the housing;
- a second acquisition means obtaining an output value of a second sensor that detects the striking on the struck head;
- a memory control means storing information that is based on the output value obtained by the first acquisition means in a memory means;
- a striking detection means detecting the striking, which triggers sound generation, on the struck head based on the output value obtained by the second acquisition means;
- a determining means, wherein if the striking, which triggers the sound generation, is detected by the striking detection means, the determining means determines whether the housing is struck in a predetermined time interval before a timing of detecting the striking based on a content stored in the memory means;
- and
- a generation means, wherein if the determining means determines that the housing is struck in the predetermined time interval, the generation means generates musical sound control information that differs from a situation where the determining means determines that the housing is not struck in the predetermined time interval.
A sound source control information generating apparatus, adapted for generating sound source control information which controls a sound source means that generates a musical sound based on striking on a struck head of a percussion instrument that comprises a housing and the struck head, and the sound source control information generating apparatus comprising:
- a first determining means determining whether the housing is struck based on a first output value, which is an output value of a first sensor that at least detects the striking on the housing;
- a second determining means determining whether the striking on the struck head triggers sound generation based on a second output value, which is an output value of a second sensor that at least detects the striking on the struck head and is different from the first sensor;
- a third determining means determining whether the housing is struck in a predetermined time interval before the striking that triggers the sound generation based on a determination result of the first determining means and a determination result of the second determining means;
- and
- a generation means, wherein if the third determining means determines that the housing is struck in the predetermined time interval before the striking that triggers the sound generation, the generation means generates musical sound control information that differs from a situation where the third determining means determines that the housing is not struck in the predetermined time interval before the striking that triggers the sound generation.
A sound source control information generating method, adapted for generating sound source control information which controls a sound source means that generates a musical sound based on striking on a struck head of a percussion instrument that comprises a housing and the struck head, and the sound source control information generating method comprising:
- using a first determining means to determine whether the housing is struck based on a first output value, which is an output value of a first sensor that at least detects the striking on the housing;
- using a second determining means to determine whether the striking on the struck head triggers sound generation based on a second output value, which is an output value of a second sensor that at least detects the striking on the struck head and is different from the first sensor;
- using a third determining means to determine whether the housing is struck in a predetermined time interval before the striking that triggers the sound generation based on a determination result of the first determining means and a determination result of the second determining means,
- wherein if the third determining means determines that the housing is struck in the predetermined time interval before the striking that triggers the sound generation, using a generation means to generate musical sound control information that differs from a situation where the third determining means determines that the housing is not struck in the predetermined time interval before the striking that triggers the sound generation.
