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.

First claim

What is claimed is:

1. 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, and
wherein the musical sound control information is a tone control parameter or a volume control parameter.

2. The sound source control information generating apparatus according to claim 1 , wherein if the output value obtained by the first acquisition means is determined as the striking on the housing, the memory control means stores the information that is based on the output value in the memory means to identify a timing that the output value is obtained by the first acquisition means.

3. The sound source control information generating apparatus according to claim 1 , wherein the memory control means sequentially stores the information in the memory means, and the information is based on the output value obtained by the first acquisition means.

4. The sound source control information generating apparatus according to claim 1 , wherein if the output value obtained by the second acquisition means is equal to or greater than a predetermined value, the memory control means does not store the information that is based on the output value obtained by the first acquisition means in the memory means.

5. The sound source control information generating apparatus according to claim 1 , wherein the information that the memory control means stores in the memory means is the output value obtained by the first acquisition means, and
the determining means determines that the housing is struck if the output value stored in the memory means is equal to or greater than the predetermined value, and determines that the housing is not struck if the output value stored in the memory means is not equal to or not greater than the predetermined value.

6. The sound source control information generating apparatus according to claim 1 , wherein the generation means generates the musical sound control information that is based on the output value obtained by the second acquisition means if the determining means determines that the housing is not struck in the predetermined time interval, and generates the musical sound control information that is based on the output value obtained by the second acquisition means and the information stored in the memory means if the determining means determines that the housing is struck in the predetermined time interval.

7. A non-transitory computer readable medium stored with a program adapted for causing a computer to control the sound source control information generating apparatus of claim 1 .

8. 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.

9. The sound source control information generating apparatus according to claim 8 , further comprising a memory control means, wherein if the first determining means determines that the housing is struck, the memory control means stores information that is based on the first output value corresponding to the determination in the memory means to identify a timing of obtaining the first output value, and
the third determining means determines whether the housing is struck in the predetermined time interval before the striking that triggers the sound generation based on a memory content stored in the memory means.

10. The sound source control information generating apparatus according to claim 8 , further comprising a time counting means that starts counting time if the first determining means determines that the housing is struck, wherein
the third determining means determines that the housing is struck in the predetermined time interval before the striking that triggers the sound generation if the second determining means determines that the striking that triggers the sound generation occurs in a time period before the predetermined time interval lapses by the time counting means.

11. The sound source control information generating apparatus according to claim 8 , wherein the first determining means determines that the housing is struck if the first output value outputted by the first sensor is equal to or greater than a first predetermined value and the second output value outputted by the second sensor is not equal to or not greater than a second predetermined value at a timing that the first sensor outputs the first output value, and determines that the housing is not struck if the second output value outputted by the second sensor is equal to or greater than the second predetermined value at the timing that the first sensor outputs the first output value.

12. The sound source control information generating apparatus according to claim 8 , further comprising a memory control means storing the information that is based on the first output value sequentially in the memory means, wherein
the third determi
