The electronic percussion instrument disclosed herein includes a plurality of pads to which different tones are assigned, and a vibration sensor is provided for each of the plurality of pads. By providing the vibration sensor individually for each pad in this manner, it is possible to detect which pad is hit by the hitting member, and thereby, tones with different tones can be generated.

[0003]

[Problems to be solved by the device]

 However, in the conventional electronic percussion instrument, the same pad may be hit by the striking member operated by the left hand or by the striking member operated by the right hand. However, the characteristics of the generated musical sound were constant. In addition, the musical tone characteristics were not changed by hitting with a hand, hitting with a stick, or hitting with a different kind of stick. Therefore, with this electronic percussion instrument, only a monotonous and poorly expressive performance was possible. The present invention has been made in view of the above-mentioned points, and an object thereof is to provide an electronic percussion instrument capable of performing a performance rich in expression.

[0004]

[Means for Solving the Problems]

 The electronic percussion instrument according to the present invention has a performance operator having a pressed surface for performing a pressing for instructing the generation of a musical sound, a pressing member for pressing the pressed surface, and a pressing surface for pressing the pressed surface. In response to the detection means for detecting that an operation has been performed, the instruction means provided on the pressing member for instructing change control of the characteristic of the musical sound, and the pressing force on the pressed surface detected by the detection means. And a tone control means for generating a tone signal and controlling the characteristics of the tone signal in response to an instruction from the instructing means.

[0005]

[Action]

 The detection means detects that a pressing operation has been performed on the pressed surface. In this way, when the detection means detects that the pressing operation has been performed on the pressed surface, the musical sound control means generates a musical sound signal in response to the detection. Further, the instruction means gives an instruction to change the characteristic of the musical sound. In this way, when the musical tone characteristic changing control is instructed by the instruction means, the musical tone control means controls the characteristics of the musical tone signal such as tone color, volume and pitch in accordance with the instruction.

With the above configuration, for example, a pressing member provided with a sensor or a finger for detecting a striking motion, an instruction means such as a switch for switching with a palm or the like and a pressing member not provided with the instruction means, or a finger of a human body, a hand , Etc., the pressing surface of the performance operator is pressed by using two pressing members that are operated by the left and right hands of the performer. When is pressed by the pressing member provided with the instructing means and the instructing means is instructed to change the tone characteristic, the characteristic of the tone signal is controlled in accordance with this instruction. In this way, a member having the indicating means and a member not having the indicating means are respectively held by the left and right hands of the performer, and the performer uses the left and right hands separately to perform various musical tone controls. It becomes possible, and it becomes possible to perform with rich expressive power.

[0007] Here, "pressing" is a concept including hitting that can be said to be relatively strong pressing and contact that can be said to be extremely weak pressing. Therefore, the present invention can be applied to the case where the pressing member strikes the pressed surface and the case where the pressing member contacts the pressed surface. That is, in the former case, the characteristic of the musical sound signal is controlled by detecting the impact pressure received from the pressed surface by the pressing member, and in the latter case, the contact of the pressing member from the pressed surface is controlled. The characteristic of the musical tone signal may be controlled by detecting the repulsive force and the like.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 shows an example of an electronic percussion instrument embodying the present invention. The electronic percussion instrument comprises a percussion instrument body 2 and two striking members 4, 6 such as sticks.

The percussion instrument body 2 includes a plurality of pads PA, PB, PC and PD as performance operators, and these pads PA to PD have different tones (for example, percussion instrument, snare percussion instrument). , Tones such as cymbals) are respectively assigned. Further, a vibration sensor 9 for detecting that the pads PA to PD have been hit is provided inside or on the back surface side of each of the pads PA to PD. When any one of the pads (hereinafter, any one of the pads is indicated by P) is hit, the vibration sensor 9 corresponding to the pad P detects the vibration applied to the pad P, and hits in response to this. It outputs the detection signal STR. This batting detection signal STR is given to an electronic circuit section provided in the percussion instrument body 2.

The hitting members 4 and 6 are operated by being hit by the left and right hands of the performer in order to hit the pads PA to PD. On one of the striking members 6, an impact sensor 10 for detecting an impact generated on the striking member 6 when the pads PA to PD are striking by the striking member 6 is installed at the tip of the striking member 6 or in the vicinity thereof. It is attached. That is, when one of the pads P is hit by the hitting member 6, the shock sensor 10 detects the shock generated in the hitting member 6 and outputs a shock detection signal IMP corresponding to this. The impact detection signal IMP is given to the electronic circuit section provided in the percussion instrument body 2 via the line 11. The shock detection signal IMP may be wirelessly applied to the electronic circuit section without passing through the line 11.

FIG. 2 is a circuit block diagram for explaining the overall configuration of this electronic percussion instrument. The output of each vibration sensor 9 provided for each of the pads PA to PD is connected to two gates G 1 and G 2, and the outputs of the gates G 1 and G 2 are the first input of the tone signal generating circuit 14. IN1 and the second input IN2 are respectively connected. The output of the impact sensor 10 attached to the striking member 6 is output via the one-shot pulse generation circuit 15 to the negative logic control input of each gate G1 and the positive logic control input of each gate G2. It is connected to the. The one-shot pulse generation circuit 15 generates a pulse signal having a predetermined time width in response to the rise of the shock detection signal IMP given from the shock sensor 10. Alternatively, the one-shot pulse generation circuit 15 may generate an output signal by waveform-shaping the impact detection signal IMP into a binary pulse signal of "1" and "0".

The tone parameter memory 18 stores parameters for generating tone signals related to the pads PA to PD, and the parameters of the pads PA to PD are tone color controls for left hand operation. It includes a parameter and a tone color control parameter for the right hand operation, which is different from the parameter for the left hand operation. The gates G1 and G2 provided for each vibration sensor 9 output a hit detection signal STR from the vibration sensor 9 1 as a musical tone signal according to which hitting member 4 or 6 hits the corresponding pad P 1. It passes or is prohibited from passing through the generation circuit 14.

That is, when the corresponding pad P is struck by the impact member 6 having the impact sensor 10, the one-shot pulse generation circuit 15 outputs a positive logic pulse signal to thereby cause the gate G1. , The negative logic control input of which is deactivated, and the positive logic control input of gate G2 is activated. Thus, while the gate G 1 is in the passage prohibited state, the gate G 2 is in the passage enabled state, and the impact detection signal STR from the vibration sensor 9 is transmitted through the gate G 2 to the first part of the tone signal generation circuit 14. It is input to the second input IN2. On the other hand, when the corresponding pad P is hit by the hitting member 4 that does not include the impact sensor 10, no signal is output from the one-shot pulse generation circuit 15, so the negative logic control input of the gate G1 is When activated, the positive logic control input of gate G2 is deactivated. Thus, while the gate G1 is in the passable state, the gate G2 is in the pass-disabled state, and the hit detection signal STR from the vibration sensor 9 is input to the tone signal generation circuit 14 via the gate G1. Taken in IN1.

In the tone signal generation circuit 14, the corresponding pad P is hit by the operation of either the left or right hand, depending on which of the first input IN1 and the second input IN2 the hit detection signal STR is input to. It detects whether or not there is a tone, and generates a tone signal with the characteristics according to this detection. That is, for example, when the batting detection signal STR is input to the first input IN1 in a performance in which the batting member 4 is operated with the left hand and the batting member 6 is operated with the right hand, in the tone signal generation circuit 14, the pad P Is determined to have been struck by the left hand operation. In this way, the tone signal generating circuit 14 reads out from the tone parameter memory 18 the parameters including the tone color control parameters for left hand operation among the parameters relating to the pad P, and generates tone signals in accordance with the parameters.

When the hit detection signal STR is input to the second input IN2, the musical tone signal generating circuit 14 determines that the pad P is hit by the hitting member 6, that is, the right hand operation. Of the parameters relating to the pad P, the parameters including the tone color control parameters for the right hand operation are read from the tone parameter memory 18 and a tone signal is generated according to the parameters.

The musical tone signal generated by the musical tone signal generating circuit 14 as described above is acoustically produced as a musical tone through the sound system SS. The tones thus produced have different tones when the pad P is hit by the left-hand operation and when the pad P is hit by the right-hand operation.

In the above embodiment, the tone color of the musical tone is controlled by using different parameters depending on the presence or absence of the output of the impact sensor 10, but the output of the impact sensor 10 is not limited to this. Of course, the tone volume, pitch, etc. may be controlled appropriately according to the value of the signal. Furthermore, by dividing each pad PA to PD into a plurality of segments and providing a vibration sensor 9 for each segment, it is possible to detect which segment of each pad PA to PD has been hit, and also consider this segment detection. It is more effective if the control is done.

Further, in the above embodiment, when the player uses two striking members operated with both hands, an example of controlling the characteristics of the musical sound by detecting the impact received by one of the striking members will be described. did. However, the present invention is not limited to this, and is applicable to the case where only one striking member is used and the striking by the striking member and the striking by the bare hand of the player are used together. The characteristics of the musical sound are controlled by detecting the impact received by the striking member. In short, the present invention can be applied to all cases in which the impact member whose impact is detected by the impact sensor is used together with the impact member that is not the detection target or the player's hand etc. to strike the pad. is there. It is also possible to use, for example, a finger sack or a glove-shaped member as the pressing member, and incorporate the vibration sensor therein.

Further, in the above embodiment, the impact sensor is provided on the stick and the musical tone characteristics are changed and controlled according to the output of the impact sensor. However, the present invention is not limited to this, and as shown by the dotted line in FIG. In addition, a push button type switch 10 'such as a tact switch is provided in the grip portion of the stick 6 or in the vicinity thereof so as to change and control the tone characteristic in accordance with ON / OFF operation of the push button type switch 10'. Good. As a result, when the pad P is hit with a stick, the musical tone generated by turning on / off the switch 10 'can be made different. Therefore, for example, by repeating the on / off operation of the switch 10 'during striking, it is possible to alternately produce hi-hat sounds, bass drum sounds, hi-hat open sounds, and hi-hat closed sounds. The tone characteristics can be changed and controlled with.

In the above embodiment, the electronic percussion instrument having a plurality of pads has been described, but the present invention may be applied to an electronic percussion instrument having only one pad. Further, the present invention is not limited to the electronic percussion instrument that controls the characteristics of the musical sound by generating a musical sound in response to the striking of the pad and detecting the impact received by the striking member with the striking. In other words, this invention controls the characteristics of a musical sound by generating a musical sound in response to pressing (including contact) with the pad and detecting the repulsive force received by the pressing member from the pad in response to the pressing. Good. In this case, a pressure sensor will be used instead of the impact sensor.

Further, the performance operator is not limited to the drum pad or the striking surface similar to the percussion instrument as in the above embodiment, but may be a keyboard or a doublet switch. In that case, for example, a finger sack or a glove-shaped member may be used as the pressing member, and the pressing force sensor may be incorporated in the member by a pressure sensor or conductive rubber. By doing so, simple touch response control can be performed without incorporating a touch sensor mechanism on the keyboard or doublet switch side.
