TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation mechanism for controlling an effect applying function of an electronic musical instrument that can be operated by a player with one hand and operated when an effect is applied to a performance sound of the electronic musical instrument.
[0002]
[Prior art]
Conventionally, some electronic keyboard instruments include a bender wheel 90 and a modulation wheel 92 as shown in FIG. The bender wheel 90 is for manually controlling the function of giving the effect of changing the pitch of the musical tone to the musical tone, and continuously changes the pitch of the musical tone within a range of about one tone according to the operation amount. Therefore, it is possible to provide an effect of intentionally changing the musical sound so as to swing up and down. The modulation wheel 92 is for manually controlling a function of giving an effect such as vibrato to a musical tone, and can change the effect giving level according to the operation amount.
[0003]
Further, the bender wheel 90 and the modulation wheel 92 may be operated at the same time when a more complicated changing effect is applied to a musical sound. Therefore, in many cases, the bender wheel 90 and the modulation wheel 92 are arranged side by side on the upper surface near the left end of the electronic keyboard instrument, and even when the player is operating the keyboard 94 with the right hand, the bender wheel 90 and the modulation wheel 92 are often used. Both of them can be operated simultaneously with the left hand.
[0004]
[Problems to be solved by the invention]
When the bender wheel 90 is operated alone, many players place their left hands on the case 96 in such a manner as to grab the left end of the case 96 and operate the bender wheel 90 using their thumbs. If the operation is performed in such a posture, the position of the left hand is unlikely to swing up, down, left, and right, and the left hand is easily stabilized, so that a delicate operation can be performed accurately.
[0005]
On the other hand, when both the bender wheel 90 and the modulation wheel 92 are operated, many players operate the bender wheel 90 with the middle finger and the forefinger for convenience of operating with two fingers. Is used to operate the modulation wheel 92.
[0006]
However, when the bender wheel 90 and the modulation wheel 92 are operated with the middle finger and the forefinger in this manner, the left hand is placed on the case 96 in such a manner as to grip the left end of the case 96, as when operating the bender wheel 90 with the thumb. This makes it impossible to perform such operations, so that the position of the left hand is likely to be unstable, which has the disadvantage of hindering delicate operations. Further, since it is more difficult to operate the bender wheel 90 with the middle finger than to operate it with the thumb, even a player who can skillfully operate the bender wheel 90 with the thumb further operates the bender wheel 90 with the middle finger. I had to practice.
[0007]
SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and an object of the present invention is to operate a first operation means used as a bender wheel or the like in a position that is most easy to operate, and furthermore, perform a modulation operation in that position. It is another object of the present invention to provide an operation mechanism for controlling an effect imparting function of an electronic musical instrument that can be configured to be able to operate a second operation means used for another operation such as the above.
[0008]
Means for Solving the Problems and Effects of the Invention
In order to achieve the above object, an operation mechanism for controlling an effect imparting function of an electronic musical instrument according to claim 1,
The player is provided with first and second operation means that can be operated simultaneously by one hand with one hand and can output a signal corresponding to the operation amount, and an effect of an electronic musical instrument is given based on the signal output from each operation means. In an operation mechanism for controlling an effect giving function of an electronic musical instrument whose function is controlled,
The first operating means includes a movable portion capable of rotating or sliding operation, and a first signal output portion capable of outputting a signal corresponding to the position of the movable portion,
The second operating means includes a second signal output unit that outputs a signal corresponding to a pressing force when the pressing operation is performed.,
In addition, the first operating means is arranged at a place where it can be operated using the thumb,
When the second operating means is placed on a place where the first operating means can be operated using a thumb, the second operating means is arranged on a place where the same operating means can be operated using fingers other than the thumb.
It is characterized by the following.
[0009]
According to this operating mechanism, when the movable portion of the first operating means is rotated or slid, a signal corresponding to the position of the movable portion is output from the first signal output portion. The first effect imparting function of the musical instrument can be controlled. Further, when the second operating means is pressed, a signal corresponding to the pressing force is output from the second signal output unit. Therefore, it is possible to control the second effect imparting function of the electronic musical instrument using the signal as a parameter. it can.
[0010]
Here, the first operation means operates in the same manner as the bender wheel described as the prior art, so that the first operation means can be operated by the thumb with the hand placed on the case of the musical instrument, for example. , The first operating means may be arranged. On the other hand, unlike the bender wheel or the modulation wheel described as the related art, the second operation means outputs a signal corresponding to the pressing force when the pressing operation is performed. For this reason, there is no need to use a finger to perform an operation that significantly displaces the movable part.FingerThe second operation means may be arranged at a place where the user can appropriately perform a pressing operation. As a result, the first operation means used as a bender wheel or the like can be operated in the position that is most easy to operate, and the second operation means used for another operation such as a modulation operation can be operated in that position. Become like
[0011]
Therefore, according to this operation mechanism, it is not necessary to change the finger used when operating the first operation means or change the place of the hand depending on whether or not to operate the second operation means. Since it is possible to improve the operation, regardless of whether the second operation means is operated or not, the two operation means can be satisfactorily operated at the same time in a state where the hand position is stabilized.
Further, when the first operation means is arranged at a place where the thumb can be operated, and the second operation means places the hand at a place where the first operation means can be operated with the thumb. Since it is arranged in a place where it can be operated using fingers other than the thumb of the same hand, the second operation means can be operated with another finger of the same hand while operating the first operation means with the thumb. . Therefore, it is easier to delicately operate the second operation means.
Next, the operating mechanism for controlling the effect imparting function of the electronic musical instrument according to the second aspect of the present invention includes:
The first operating means is arranged on the upper surface side near the side edge of the electronic keyboard instrument,
The second operating means is arranged on a side surface near a side end of the electronic keyboard instrument.
It is characterized by the following.
According to such an operation mechanism for controlling the effect imparting function, the user can place the hand in such a manner as to grasp the vicinity of the upper side end of the electronic keyboard instrument, and operate the first operation means with the thumb in that state, and At the same time, the second operation means can be operated with another finger, so that the hand can be operated without stabilizing the position of the hand without swinging left and right or up and down.
The first and second operating means may be arranged on the upper surface side of the electronic keyboard instrument in addition to the place as described in the second aspect. Although it is possible, the arrangement according to the second aspect is more stable because the hands can be placed so as to grasp the corners of the musical instrument.
[0012]
Next, the claim3The operation mechanism for controlling the effect imparting function of the electronic musical instrument described in the above,
The second operating means includes, as the second signal output unit, a planar pressure-sensitive resistor in which electric resistance between terminals changes according to a pressing force when a pressing operation is performed.
It is characterized by the following.
[0013]
In this operating mechanism, the second operating means includes a planar pressure-sensitive resistor. In principle, this planar pressure-sensitive resistor has an infinite number of contacts inside the planar body, and when pressing force is applied to the planar body, more contacts are closed and the electrical resistance decreases. It is something.
[0014]
More specifically, for example, a conductive filler is dispersed in a rubber-like base material to form a conductive elastic material, and the conductive elastic material is formed in a planar shape, and the positive and negative electrodes are formed on the surface of the planar body. Can be considered. In this case, the positive and negative terminals are electrically connected via the conductive elastic material, and a certain electrical resistance value appears between the positive and negative terminals. When a pressing force acts on the portion, the rubber-like base material in the conductive elastic material is compressed, and the portions that have not been in contact with the conductive filler come into contact with each other. The electric resistance between terminals decreases. That is, when viewed microscopically, the conductive filler dispersed in the rubber-like base material forms countless contacts that are normally open and closed when pressed, and as the pressing force increases, The number of contacts to be closed increases and the electrical resistance decreases.
[0015]
According to the operating mechanism for controlling the effect imparting function of the electronic musical instrument configured as described above, the second operating means includes the above-described planar pressure-sensitive resistor, so that the second operating means can be used. It can be made very thin. Therefore, the degree of freedom in arranging the second operation means is higher than that in the case where the pressing force is detected by using a pressure detection device incorporating a large-scale mechanism. Thus, the second operation means can be very easily arranged at an optimum place.
[0016]
The above claims3It is needless to say that in the operating mechanism described in the above, the second operating means may include a member other than the planar pressure-sensitive resistor in addition to the planar pressure-sensitive resistor. Specifically, it is optional to provide a functionally necessary member such as a protection member for protecting the surface of the planar pressure-sensitive resistor. It is also possible to add some members from a design point of view.
[0017]
Next, the claim4The operation mechanism for controlling the effect imparting function of the electronic musical instrument described in the above,
The second operating means includes a plurality of the second signal output units formed at locations to be determined as different pressing positions.
It is characterized by the following.
[0018]
In this operation mechanism, the plurality of second signal output units are unit structures each capable of independently outputting a signal corresponding to a pressing force, and usually, a plurality of the second signal output units are arranged at a pitch at which the unit structures should be identified as different pressing positions. Is done. With this configuration, for example, by repeatedly scanning the plurality of second signal output units on the signal input side, the largest pressing force among the signals output from the respective second signal output units can be obtained. The pressing force can be obtained by searching for a corresponding signal, and the arrangement position of the second signal output unit that has detected the pressing force can be determined as the pressing position.
[0019]
Therefore, according to this operation mechanism, when the second operation means is pressed, two pieces of information, that is, the pressing force and the pressing position can be obtained, and thus the second effect imparting function of the electronic musical instrument is controlled using the pressing force as a parameter. In addition to the above, it is possible to control the third effect imparting function provided in the electronic musical instrument using the pressed position as a parameter.
[0020]
Incidentally, in using the pressed position as a parameter for controlling the third effect imparting function, various utilization methods can be considered.
For example, the effect imparting level of the third effect imparting function can be variably controlled in ten steps from “1” to “10”, and the coordinate values “1” to “10” of the pressed position of the second operating means can be specified, If the effect imparting level of the third effect imparting function is set to “A” and the player presses the pressing position of the coordinate value “B”, the effect imparting level of the third effect imparting function is changed to “A”. The change may be immediately made from "A" to "B" (that is, the effect application level is changed instantaneously), or "A" is changed to "B" so that the change is completed within a predetermined time (for example, in three seconds). May be changed continuously (that is, the time until the change of the effect applying level is completed), or “A”, “A + 1”, “A + 2”, …, “B-1”, “B” (A <B in this case; however, when B ≧ A depending on the pressed position, Ri obtained) may be continuously changed so on (i.e., specific time of changing one step to effect application level). Other than the instantaneous change, the operation can be interrupted when the desired effect imparting level is reached while listening to the change in the musical sound. These changes indicate that there is a one-to-one correspondence between the coordinate values “1” to “10” of the pressed position and the effect application levels “1” to “10” of the third effect application function. This is a prerequisite change method.
[0021]
On the other hand, there is a method in which the relative displacement of the pressed position is used as a parameter instead of such a one-to-one correspondence.
For example, the effect application level of the third effect application function can be changed from “1” to “10”, the coordinate values “1” to “10” of the pressed position of the second operation unit can be specified, and the current third Is set to “A”, the player presses the pressed position of the coordinate value “B”, and slides the pressed position to the coordinate value “B + C” as it is. The degree to which the effect is applied may be changed in real time from “A” to “A + C” in conjunction with the slide of the pressing position, or may be changed so that the change is completed within a predetermined time (for example, in 3 seconds). “A” may be continuously changed from “A” to “A + C” (that is, the time until the change of the effect imparting level is completed), or “A”, “A + 1” every predetermined time (for example, every 0.5 seconds). , "A + 2", ..., "A + C-1", "A + C" (C> 0 in this case) However, the degree also possible), such cases C ≦ 0 by pressing position may be changed continuously (i.e., specific time of changing one step to effect application level). Each of these changes is a change method in which a relative change in the pressed position is added to the current effect applying level of the third effect applying function.
[0022]
The above claims4In the case of the operation mechanism described in the above, even if it is desired to control only the second effect imparting function, if careless operation is performed, the pushing position is also changed when the pushing operation is performed, and the third effect imparting is performed. It may have some effect on the function.
[0023]
In order to prevent such a problem, it is preferable that whether to control the third effect imparting function be selectively set by another switch or the like. In this way, even if an unnecessary change of the pressed position is performed during the pressing operation, the operation of changing the pressed position is ignored, and the second effect providing function is controlled without affecting the third effect providing function. it can. Conversely, if the setting for ignoring the operation of applying the pressing force can be set, only the third effect applying function can be controlled without controlling the second effect applying function.
[0024]
Further, a configuration may be adopted in which a certain pressing force is set as a threshold value, and a pressing force below the threshold value is ignored. In this case, if the operation of changing the pressing position by lightly touching the movable portion (in a state where only the pressing force equal to or less than the threshold is applied) is performed, the third effect can be obtained without affecting the second effect providing function. The application function can be controlled. Similarly, the change of the pressing position may be configured to ignore the minute displacement. In this case, even if the pressing position is slightly shifted during the operation of applying the pressing force, the second effect applying function can be controlled without affecting the third effect applying function.
[0025]
Next, the claim5The operation mechanism for controlling the effect imparting function of the electronic musical instrument described in the above,
The second operation means includes a third signal output unit that outputs a signal corresponding to a pressed position when the pressing operation is performed.
It is characterized by the following.
[0026]
Here, since the third signal output unit only needs to be able to detect only the pressed position, it can be configured using, for example, various film-shaped touch panels that have already been put into practical use. With a flexible film-shaped touch panel, detection of the pressing force will not be hindered even if it is arranged so as to overlap with the second signal output unit.
[0027]
According to the operation mechanism configured as described above, when the second operation unit is pressed, the second signal output unit outputs a signal corresponding to the pressing force, and the third signal output unit outputs the signal corresponding to the pressing position. Output a signal corresponding to4Similarly to the operation mechanism described above, in addition to controlling the second effect imparting function provided in the electronic musical instrument using the pressing force as a parameter, it is also possible to control the third effect imparting function included in the electronic musical instrument using the pressed position as a parameter. become able to. It should be noted that the pressing position is defined in the claim.4As in the case of the operation mechanism described above, it can be used as a parameter for controlling the third effect providing function in various ways.
[0028]
Next, the claim6The operation mechanism for controlling the effect imparting function of the electronic musical instrument described in the above,
The second operating means has a structure in which a pressing operation can be performed on a planar portion in which a coordinate system defined by two intersecting coordinate axes is assumed, and the pressing position is represented according to the coordinate system. It is configured so that a set of the first and second coordinate values can be specified.
It is characterized by the following.
[0029]
In this operating mechanism, the pressing position can be specified.4Or claims5And the same specific means can be employed, but in particular, since the pressed position can be specified as the first and second coordinate values, the third effect is provided using the first coordinate value as a parameter. In addition to controlling the function, the fourth effect imparting function can be controlled using the second coordinate value as a parameter, so that various effects can be imparted.
[0030]
Incidentally, in controlling the fourth effect imparting function, the effect imparting level thereof can be determined in the same manner as described for the third effect imparting function.
The above claims5Also, in the case of the operation mechanism described in the above, if the operation is performed carelessly when the effect application level of the third effect application function is changed, the effect application level of the fourth effect application function is erroneously changed. If it is necessary to prevent such a problem, it is necessary to determine which one of the third and fourth effects is to be changed by using another switch or the like. It is good to be able to set it selectively by using.
[0036]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of the present invention will be described with an example.
As shown in FIG. 1, an electronic keyboard instrument described as the first embodiment has a left brace 12 formed near the upper left end of a case, and the left brace 12 is provided with a first brace of the present invention. A bender wheel 14 corresponding to the operation means is disposed, and a modulation pad 16 corresponding to the second operation means of the present invention is disposed on the side surface of the left brace 12.
[0037]
The bender wheel 14 has exactly the same structure as that conventionally used in this type of electronic keyboard instrument, is rotatably supported, and has a rotary variable resistor disposed inside the electronic keyboard instrument. It is connected to a rotating shaft of a container (not shown) via an operation transmitting member (not shown) such as a gear or a shaft.
[0038]
When the bender wheel 14 is turned, the turning shaft of the variable resistor turns to change the electric resistance value appearing between the terminals of the variable resistor. Therefore, the operation amount of the bender wheel 14 can be detected based on the change in the resistance value, and the tone control according to the operation amount of the bender wheel 14 can be realized. Specifically, the control unit incorporated in the electronic keyboard instrument detects that the bender wheel 14 has been rotated from the back side to the front side from the change in the resistance value, and generates a tone according to the operation amount. The control for lowering the pitch of the musical tone is performed, or conversely, the rotation operation is detected, and the control for raising the pitch of the musical tone is performed in accordance with the operation amount.
[0039]
A spring that is elastically deformed in accordance with the rotation operation is wound around the bender wheel 14, and the elastic force of the spring causes the bender wheel 14 to automatically move from the position after the rotation operation to the origin position. It is designed to return.
The modulation pad 16 is employed in place of the modulation wheel (see FIG. 5) described as a conventional technique. As shown in FIG. 2, the modulation pad 16 is provided inside an annular projection 20 protruding from the side surface of the left brace 12. A planar pressure-sensitive resistor 22 is arranged, and a pad 24 made of an elastic material is arranged thereon.
[0040]
The planar pressure-sensitive resistor 22 forms a pair of comb-shaped conductors 31 and 32 on the surface of the first insulating film 30, while the pressure-sensitive conductive material is formed on the surface of the second insulating film 34. It has a structure in which a polymer layer 36 is formed and the comb-shaped conductors 31 and 32 and the pressure-sensitive conductive polymer layer 36 are stacked so as to be in contact with each other.
[0041]
The pressure-sensitive conductive polymer layer 36 is a composite material obtained by adding a conductive filler to a rubber-like insulating polymer as a base material. In a state where no pressure is applied, the pressure-sensitive conductive polymer layer 36 exhibits an extremely high electric resistance value, and is subjected to pressure. And the number of contact points of the conductive filler in the pressure-sensitive conductive polymer layer 36 increases, and the electric resistance value decreases.
[0042]
The comb-shaped conductors 31 and 32 are electrically connected via the pressure-sensitive conductive polymer layer 36. Lead wires 37 and 38 are connected to the comb-shaped conductors 31 and 32, respectively, and the lead wires 37 and 38 are connected to the electronic members via holes 39 formed in the left-arm part 12 inside the annular protrusion 20. It is introduced inside the keyboard instrument.
[0043]
In the planar pressure-sensitive resistor 22 configured as described above, the electric resistance value of the pressure-sensitive conductive polymer layer 36 decreases as the pressing force increases, and as a result, the electric resistance appearing between the comb-shaped conductors 31 and 32. The resistance value (that is, the electric resistance value detected via the lead wires 37 and 38) decreases. Therefore, the pressing force received by the modulation pad 16 can be detected based on the change in the resistance value, and the tone control according to the pressing force can be realized. Specifically, the control unit incorporated in the electronic keyboard instrument detects that the modulation pad 16 is pressed from the change in the resistance value, and determines the degree of modulation applied to the musical tone in accordance with the pressing force. Control to change.
[0044]
In the electronic keyboard instrument configured as described above, the left hand of the left hand arm is held in such a manner that the player grasps the left hand arm 12 with the left hand while operating the keyboard using the right hand. It is possible to take the most natural posture for the player by placing the unit on the unit 12 and rotating the bender wheel 14 with the thumb of the left hand in that state, without changing the position of the left hand. Then, a finger other than the thumb can be placed on the modulation pad 16 to perform a pressing operation on the modulation pad 16.
[0045]
Therefore, unlike the related art, it is not necessary to change whether the bender wheel 14 is operated with the thumb or the middle finger depending on whether or not the modulation operation is performed, and the player always performs the bender operation and the natural posture in a natural posture. A modulation operation can be performed.
[0046]
In the electronic keyboard instrument configured as described above, it is desirable that the relationship between the pressing force detected by the modulation pad 16 and the degree of modulation can be variably set in several patterns.
For example, the first pattern in which the rate of increase in the degree of modulation when the pressing force increases in a range where the pressing force is weaker is larger, and the rate of increase in the degree of modulation when the pressing force increases regardless of the magnitude of the pressing force is constant. It is possible to selectively set a second pattern such as the following, a third pattern in which the rate of increase in the degree of modulation when the pressing force increases as the pressing force increases, and the like. In this way, a player with a weak fingertip can select the first pattern in addition to the second pattern in the standard state, whereby the desired effect can be obtained even if the player touches with a light force. Will be able to do it. On the other hand, a player with a strong fingertip can select the third pattern, thereby preventing an unexpected large change from occurring even though the player intends to touch lightly.
[0047]
In addition, if a slight pressing force is recognized as a modulation operation, there is a possibility that even if the modulation operation is unnecessary, it may not even be possible to put a finger on the modulation pad 16. If a pattern is set such that a weak pressing force is set as a threshold and a pressing force higher than the threshold is recognized as a modulation operation, there is no problem even if a finger is put on the modulation pad 16.
[0048]
Next, another embodiment of the present invention will be described. In the following description, portions that are configured in the same manner as in the first embodiment are given the same reference numerals, and detailed descriptions of those portions are omitted.
As shown in FIG. 3, the electronic keyboard instrument described as the second embodiment has a left brace 12 formed near the upper left end of the case. A bender wheel 14 corresponding to the operation means is disposed, and a multi-function operation pad 51 corresponding to the second operation means of the present invention is disposed on the side surface of the left brace 12.
[0049]
The multi-function operation pad 51 has the same function as the modulation pad 16 in the first embodiment, and can also perform a pan-pot operation. As shown in FIG. The pressure-sensitive conductive polymer layer 55 used in the modulation pad 16 and the negative electrode 59 made of a conductor formed in a line on the surface of the insulating film 57 are superposed. .
[0050]
Since the multifunctional operation pad 51 thus configured has a certain length in the arrangement direction of the negative electrode 59, the conductive pad in the pressure-sensitive conductive polymer layer 55 is not applied to the portion where the pressing force is applied. Although the number of contact points of the filler increases, the number of contact points of the conductive filler in the pressure-sensitive conductive polymer layer 55 does not increase at a position distant from the portion where the pressing force is applied. Changes depending on whether or not each is pressed. Therefore, by scanning the potentials of a large number of negative electrode electrodes 59 and detecting the negative electrode 59 where the highest potential appears, the pressing position can be specified from the arrangement position of the electrodes, and at the same time, such a potential Of the multifunction operation pad 51 can be detected on the basis of the change of the electric resistance value (change of the electric resistance value), so that the tone control according to the pressed position and the pressed force can be realized. Specifically, the control unit built in the electronic keyboard instrument detects that the multi-function operation pad 51 is pressed from the change in the resistance value, and changes the pan pot left and right according to the pressed position at that time. Control to change the degree of modulation applied to the musical tone in accordance with the pressing force.
[0051]
In the electronic keyboard instrument configured as described above, the left hand of the left hand arm is held in such a manner that the player grasps the left hand arm 12 with the left hand while operating the keyboard using the right hand. It is possible to take the most natural posture for the player by placing the unit on the unit 12 and rotating the bender wheel 14 using the thumb of the left hand in that state, without changing the position of the left hand. The user can put a finger other than the thumb on the multi-function operation pad 51 to perform a pressing operation on the multi-function operation pad 51.
[0052]
Therefore, unlike the related art, it is not necessary to change whether the bender wheel 14 is operated with the thumb or the middle finger depending on whether or not the modulation operation is performed, and the player always performs the bender operation and the natural posture in a natural posture. A modulation operation can be performed. In addition, if necessary, the pan pot operation can be performed by changing the pressing position on the multifunctional operation pad 51.
[0053]
In the case of the electronic keyboard instrument configured as described above, in order to perform the panpot operation, a certain amount of pressing force must be applied to the multi-function operation pad 51, so that even a slight pressing force is recognized as a modulation operation. With such a configuration, the pan pot operation alone cannot be performed alone. With regard to this, if a certain pressing force is set as a threshold value and a pressing force equal to or higher than the threshold value is recognized as a modulation operation, a pressing operation with a weak force equal to or lower than the threshold value causes a panpot operation. Just be able to do it.
[0054]
Conversely, depending on the method of recognizing the panpot operation, when only the modulation operation is to be performed, it may be recognized as a panpot operation. In this regard, the pressing operation itself is not recognized as a panpot operation, but the relative change in the pressing position is recognized as a panpot operation, and if necessary, the pressing position greatly changes beyond a predetermined threshold. In such a case, it may be recognized as a panpot operation.
[0055]
As described above, the embodiments of the present invention have been described. However, various specific embodiments other than those described above are conceivable for the embodiments of the present invention.
For example, in the above description, the negative electrode electrodes 59 of the multi-function operation pad 51 are arranged in a line so that the linear displacement of the pressed position can be detected. However, similar negative electrode electrodes are arranged vertically and horizontally. If arranged in a matrix, a set of first and second coordinate values indicating the position of a point in the plane can be detected, so that two effects can be simultaneously controlled using each coordinate value as a parameter. .
[0056]
Further, in each of the above-described embodiments, the example in which the modulation pad 16 and the multi-function operation pad 51 are arranged on the side surface of the left brace is described. However, if sufficient operability can be ensured, they are arranged in other places. You may.
Furthermore, in each of the above embodiments, each pad has been described as the modulation pad 16 and the multi-function operation pad 51 for both the modulation operation and the pan pot operation. However, for controlling other effects such as a filter change, etc. A pad may be used, and how to combine the types of the effect imparting functions is not particularly limited. What kind of effect giving function is controlled may be selectively set by a switch or the like.
