JP 2009-300892 A

  In the above-described conventional electronic music apparatus, display control is performed so that the first display object moves on the rail object. The mode of change of the control value can be changed by changing the position of the first display object, the position of the second display object, and the shape of the rail object.

  However, it is desired to change the value of an arbitrary sound effect parameter in various ways with a simpler operation.

  An object of the present invention is to provide a sound effect data generating apparatus capable of continuously and variously changing the value of an arbitrary sound effect parameter with a simple operation.

  (1) A sound effect data generation device according to the present invention detects a first operation of placing a parameter index corresponding to a sound effect parameter on a virtual control operator placed in a virtual space having a reference axis. Detection means, placement means for placing a parameter index on the control operator based on the detected placement operation, second detection means for detecting an operation for rotating the control operator in at least one direction, and detection A rotation means for rotating the control operator together with the parameter index arranged on the control operator based on the rotation operation performed, and determining the value of the acoustic effect parameter based on the position of the parameter index based on the reference axis, Generating means for generating sound effect data based on the determined value.

  In the sound effect data generation apparatus, when a parameter index placement operation on the control operator by the user is detected, the parameter indicator is placed on the control operator in the virtual space based on the detected placement operation. . When the rotation operation of the control operator by the user is detected, the control operator is rotated together with the parameter index in the virtual space based on the detected rotation operation. The value of the sound effect parameter is determined based on the position of the parameter index based on the reference axis in the virtual space, and sound effect data based on the determined value is generated.

  Therefore, the user continuously and variously changes the value of any one or a plurality of sound effect parameters by a simple operation of arranging one or a plurality of parameter indicators on the control operator and rotating the control operator. be able to.

  (3) The sound effect data generation device may further include a display unit that displays the control operator on the screen and displays the parameter index arranged on the control operator on the screen. In this case, the user can perform the parameter index placement operation and the control operator rotation operation while visually recognizing the control operator and the parameter index displayed on the screen. Thereby, the value of one or several sound effect parameters can be adjusted easily and appropriately.

  (4) The display means displays a plurality of parameter operators corresponding to the plurality of sound effect parameters on the screen, and the parameter index displayed on the screen can adjust the sound effect parameter corresponding to the parameter index.

The data generation device includes: a third detection unit that detects an operation for changing the first range information or an operation for changing the second range information; and an operation for changing the first range information or the second range information. When a change operation is detected, there is further provided change means for linking changes in the first and second range information so that the first range information and the second range information corresponding to each other become equal. It may be provided.

  In this case, when the user changes the first range information, the adjustable range of the sound effect parameter corresponding to the parameter index is changed, and when the user changes the second range information, the sound effect corresponding to the parameter operator is changed. The adjustable range of parameters is changed. Thereby, the adjustable range can be appropriately set for each acoustic effect parameter. In this case, the other of the first and second range information corresponding to each other is also changed in conjunction with the change of one of the first and second range information corresponding to each other. Therefore, the adjustable range of the parameter operator and the parameter index can be changed with a simple operation.

  (5) The position of the parameter index on the control operator is specified by the coordinate value on the reference axis, and the sound effect data generation device uses the lower limit value in which the coordinate value of the parameter index is set in advance by the rotation of the control operator. A position control means for controlling the position of the parameter index so that the coordinate value of the parameter index is maintained at the lower limit value when it is to be reduced may be further provided.

  The position of the parameter index on the control operator is specified by the coordinate value on the reference axis, and the sound effect data generation device is configured to make the coordinate value of the parameter index larger than a preset upper limit value by the rotation of the control operator. In this case, a position control unit that controls the position of the parameter index so that the coordinate value of the parameter index is maintained at the upper limit value may be further provided.

  In these cases, the coordinate value on the reference axis of the parameter index is maintained at the lower limit value or the upper limit value even when the user rotates the control operator too much in the direction in which the value of the acoustic effect parameter decreases or increases. The value of the sound effect parameter does not become extreme, and an unnatural sound effect is prevented from being obtained.

  (6) The display unit displays a plurality of parameter operators corresponding to the plurality of sound effect parameters on the screen, and the first detection unit selects one or a plurality of parameter operations selected from the plurality of parameter operators. The operation of moving the child as one or more parameter indicators on the control operator is detected, and the arranging means arranges and displays one or more parameter indicators on the control operator based on the detected movement operation. The means may display one or a plurality of parameter indicators after arrangement on the screen.

  In this case, the user arranges the desired parameter index on the control operator by a simple operation of moving one or more selected parameter operators displayed on the screen onto the control operator on the screen. be able to.

(2) Operation Method of Sound Effect Data Generating Device 100 FIG. 2 is a diagram illustrating an example of a sound effect parameter adjustment screen displayed on the touch panel display 6. A control operator 21 and a plurality of parameter operator display areas 22 are displayed on the sound effect parameter adjustment screen 20. The control operator 21 is arranged in a three-dimensional virtual space and has a virtual spherical shape. The position in the virtual space is represented by a three-dimensional coordinate system having an X axis, a Y axis, and a Z axis. On the sound effect parameter adjustment screen 20, the upper half of the control operator 21 is displayed. The control operator 21 is displayed so as to be rotatable in all directions in the virtual space by a user operation. Specifically, the user can rotate the control operator 21 in an arbitrary direction by moving a finger while touching the surface of the touch panel display 6.

  A plurality of parameter operators 23 are displayed in each parameter operator display area 22. Different sound effect parameters are assigned to the plurality of parameter operators 23, respectively. Here, the plurality of parameter operators 23 in the upper parameter operator display area 22 are called parameter operators P1 to P4, respectively, and the plurality of parameter operators 23 in the lower parameter operator display area 22 are respectively parameter operated. They are called children P5 to P8.

  The user can place one or a plurality of parameter operators 23 among the plurality of parameter operators 23 on the control operator 21 as the parameter index 24. Since the control operator 21 has a spherical shape, the parameter index 24 located at the center of the outer surface of the control operator 21 on the sound effect parameter adjustment screen 20 is the highest position on the hemisphere and is therefore displayed as the largest. The parameter index 24 located on the outer periphery 21a of the child 21 is displayed smallest.

  Each parameter index 24 is assigned the same acoustic effect parameter as the corresponding parameter operator 23. Here, the parameter indexes 24 corresponding to the plurality of parameter operators P1 to P8 are referred to as parameter indexes p1 to p8, respectively. For example, the parameter indicators p1, p2, and p4 can be arranged on the control operator 21 by dragging the parameter operators P1, P2, and P4. The parameter operator 23 and the parameter index 24 have the same configuration.

  FIG. 3 is a schematic diagram showing the configuration of the parameter operator 23. As shown in FIG. 3, the parameter operator 23 has a circular button BU. A partial annular parameter value display area Dr for displaying parameter values is arranged along the outer periphery of the button BU. One end MIN of the parameter value display area Dr corresponds to the minimum value of the parameter value, and the other end MAX of the parameter value display area Dr corresponds to the maximum value of the parameter value.

  A parameter value display Dp indicating the parameter value is displayed in the parameter value display area Dr. The length of the parameter value display Dp changes according to the parameter value. In this case, the position of one end C1 of the parameter value display Dp represents the parameter value. On the button BU, a parameter value display C2 is displayed so as to indicate one end C1 of the parameter value display Dp. The user can change the length of the parameter value display Dp by bringing the finger into contact with the one end C1 of the parameter value display Dp and moving it. Alternatively, the direction of the parameter value display C2 can be changed by rotating the button BU with a finger. Thereby, the parameter value can be adjusted.

  In the present embodiment, a parameter value adjustable range is set. The adjustable range is a range that the parameter value can take. By setting the adjustable range, it is possible to prevent musical failure due to improper adjustment of the parameter value, and it is possible to prevent an extreme change of the parameter value due to a user operation such as rotation. A partial annular adjustable range display Da indicating the adjustable range of the parameter value is arranged along the outer periphery of the parameter value display area Dr. One end Lo of the adjustable range display Da corresponds to the lower limit value of the adjustable range, and the other end Up corresponds to the upper limit value of the adjustable range. The user can change the lower limit value of the adjustable range of the parameter value by moving the finger by touching one end Lo of the adjustable range display Da. Further, the user can change the upper limit value of the adjustable range of the parameter value by moving the finger by touching the other end Up of the adjustable range display Da.

  The configuration of the parameter index 24 corresponding to the parameter operator 23 is the same as the configuration shown in FIG. The adjustable range display Da is displayed around the parameter index 24 on the control operator 21 and the parameter value display area Dr of the parameter operator 23 corresponding thereto.

  In FIG. 2, when the user rotates the control operator 21, the position of the parameter indicator 24 on the control operator 21 changes. In the present embodiment, the Z axis corresponds to the reference axis. The Z coordinate value of the reference position of the parameter index 24 (for example, the center of the button BU) corresponds to the parameter value. As the control operator 21 rotates, the Z coordinate value of the reference position of the parameter index 24 changes and the parameter value changes. Therefore, the user can adjust the parameter value corresponding to the parameter indicator 24 on the control operator 21 by rotating the control operator 21.

  In the present embodiment, the Z coordinate value of the outer periphery 21a of the control operator 21 is zero. The Z coordinate value of the uppermost part (center of the outer surface) of the control operator 21 is the maximum value. When the parameter indicator 24 on the control operator 21 is positioned at the uppermost part on the control operator 21, the corresponding parameter value becomes the upper limit value of the adjustable range. When the parameter indicator 24 on the control operator 21 is positioned on the outer periphery 21a on the control operator 21, the corresponding parameter value becomes the lower limit value of the adjustable range.

  When the parameter indicator 24 on the control operator 21 reaches the outer periphery 21a by the rotation of the control operator 21, even if the user further rotates the control operator 21, the parameter indicator 24 is maintained at the outer periphery 21a. The Z coordinate value of is not negative and is maintained at zero. Accordingly, the corresponding parameter value is maintained at the lower limit value. On the other hand, the other parameter index 24 positioned on the inner side of the outer periphery 21 a can move until the outer periphery 21 a is reached by the rotation of the control operator 21.

  When the user changes the length of one adjustable range display Da among the parameter operator 23 and the parameter index 24 corresponding to each other, the length of the other adjustable range display Da is also changed. Further, when the user changes the parameter value display Dp or the parameter value display C2 of the arbitrary parameter operator 23, the parameter value displays Dp and C2 of the corresponding parameter index 24 on the control operator 21 are also changed, and the control operator 21 The position of the upper parameter index 24 is also changed. Thus, the parameter indicator 24 on the control operator 21 and the corresponding parameter operator 23 are interlocked with each other.

  Next, an operation example of the sound effect parameter adjustment screen 20 will be described. FIG. 4 is a diagram for explaining an operation example of the sound effect parameter adjustment screen 20. When the user rotates the control operator 21 in the direction of the solid arrow A0 in FIG. 4 in the state of FIG. 2, the positions of the parameter indexes p1, p2, and p4 on the control operator 21 change. Since the parameter index p1 moves away from the top of the control operator 21, the corresponding parameter value decreases as the Z coordinate value at the position of the parameter index p1 decreases. Since the parameter index p2 approaches the top of the control operator 21, the corresponding parameter value increases as the Z coordinate value at the position of the parameter index p2 increases. Since the parameter index p4 reaches the outer periphery 21a of the control operator 21, the Z coordinate value at the position of the parameter index p4 becomes 0, and the corresponding parameter value is maintained at the lower limit value.

  Next, as indicated by a dotted arrow A1, the user can remove the parameter index p1 from the control operator 21 by dragging the parameter index p1 on the control operator 21 to the outside of the control operator 21 with a finger. it can. In this case, the parameter index p1 is deleted. At the same time, the adjustable range display Da of the parameter operator P1 in the parameter operator display area 22 is deleted. As indicated by a one-dot chain line arrow A2, the user can place the parameter index p5 on the control operator 21 by dragging the parameter operator P5 in the parameter operator display area 22 into the control operator 21 with a finger. it can. In this case, an adjustable range display Da is added to the parameter operator P5 in the parameter operator display area 22.

(3) Functional configuration of sound effect data generation device 100 FIG. 5 is a block diagram showing a functional configuration of the sound effect data generation device 100 according to the embodiment of the present invention. As illustrated in FIG. 5, the acoustic effect data generation device 100 includes a storage unit 101, a detection unit 102, an arrangement unit 103, a rotation unit 104, a display unit 105, a change unit 106, a control unit 107, and a generation unit 108.

  The storage unit 101 includes the RAM 9 and the storage device 13 shown in FIG. The storage unit 101 stores a sound effect parameter list L1 (FIG. 6) described later. Further, in the RAM 9 of the storage unit 101, a control target parameter list L2 (FIG. 7) is generated by a sound effect data generation process described later. The display unit 105 includes the touch panel display 6 and displays the sound effect parameter adjustment screen 20 of FIG. Further, the CPU 11 executes a sound effect data generation program stored in the ROM 10 or the storage device 13, whereby the detection unit 102, the arrangement unit 103, the rotation unit 104, the display unit 105, the change unit 106, the control unit 107, and the generation unit 108. The function is realized.

  The detection unit 102 detects an operation of the sound effect parameter adjustment screen 20 displayed on the touch panel display 6 of FIG. Specifically, the detection unit 102 performs an operation for rotating the control operator 21, an operation for placing the parameter indicator 24 on the control operator 21, an operation for removing the parameter indicator 24 from the control operator 21, and a parameter operator 23. The operation for changing the adjustable range display Da and the parameter value displays Dp and C2, the operation for changing the adjustable range display Da of the parameter index 24, and the like are detected.

  The arrangement unit 103 arranges the parameter index 24 on the control operator 21 and removes the parameter index 24 from the control operator 21 based on the operation detected by the generation unit 108. The rotating unit 104 rotates the control operator 21 based on the operation detected by the detecting unit 102. Based on the operation detected by the detection unit 102, the changing unit 106 changes the adjustable range display Da of the parameter operator 23 and the parameter index 24, or changes the parameter value displays Dp and C2 of the parameter operator 23. . The control unit 107 controls the position of the parameter index 24 when the control operator 21 rotates. For example, when the parameter indicator 24 is positioned on the outer periphery 21a by the rotation of the control operator 21, the control unit 107 maintains the parameter indicator 24 on the outer periphery 21a. The generation unit 108 determines a parameter value based on the Z coordinate of the position of the parameter indicator 24 on the control operator 21, and generates the determined parameter value as sound effect data.

(4) Sound effect parameter list L1 and control target parameter list L2
FIG. 6 shows an example of the sound effect parameter list L1. FIGS. 7A, 7B, and 7C are diagrams showing examples of the control target parameter list L2.

(5) Operation of Sound Effect Data Generating Device 100 FIGS. 8 to 10 are flowcharts showing sound effect data generating processing performed by the sound effect data generating device 100. FIG. The sound effect data generation process in FIGS. 8 to 10 is performed by the CPU 11 in FIG. 1 executing the sound effect data generation program stored in the ROM 10 or the storage device 13.

  First, the CPU 11 displays the sound effect parameter adjustment screen 20 on the touch panel display 6 (step S1). Next, the CPU 11 determines whether or not a display switching instruction to another screen has been detected (step S2). When detecting a display switching instruction to another screen, the CPU 11 ends the sound effect data generation process. When the display switching instruction to another screen is not detected, the CPU 11 determines whether or not the rotation operation to the control operator 21 is detected (step S3).

  When the rotation operation to the control operator 21 is detected, the CPU 11 determines whether or not the parameter index 24 is on the control operator 21 (step S4). When the parameter indicator 24 is present on the control operator 21, the CPU 11 executes a control operator rotation process shown in FIG. 11 described later (step S5), and proceeds to step S6. If the rotation operation of the control operator 21 is not detected in step S3 and if the parameter index 24 is not present on the control operator 21 in step S4, the CPU 11 proceeds to step S6.

  In step S6, the CPU 11 determines whether or not a removal operation of the parameter index 24 from the control operator 21 has been detected (step S6). When the removal operation of the parameter index 24 is detected, the CPU 11 deletes the corresponding parameter index from the control target parameter list L2 (step S7). For example, when the removal operation of the parameter index p4 shown in FIG. 4 is performed, the parameter index p4 and the corresponding parameter value, lower limit value, upper limit value, and position from the control target parameter list L2 in FIG. Is deleted. As a result, the control target parameter list L2 is in the state shown in FIG. Further, the CPU 11 deletes the display of the parameter indicator 24 on the control operator 21 (step S8), and deletes the adjustable range display Da of the corresponding parameter operator 23 in the parameter operator display area 22 (step S9). The process proceeds to step S10. Even when the removal operation of the parameter index 24 is not detected in step S6, the CPU 11 proceeds to step S10.

  In step S <b> 10, the CPU 11 determines whether or not an operation for placing the parameter index 24 on the control operator 21 is detected. When detecting the placement operation of the parameter index 24, the CPU 11 adds the corresponding parameter index 24 to the control target parameter list L2 (step S11). For example, when the placement operation of the parameter index p5 shown in FIG. 4 is performed, the parameter index p5 and the corresponding parameter value, lower limit value, upper limit value, and position are displayed in the control target parameter list L2 of FIG. Is added. As a result, the control target parameter list L2 is in the state shown in FIG. Further, the CPU 11 displays the corresponding parameter index 24 on the control operator 21 (step S12), and the parameter value of the control target parameter list L2 can be adjusted based on the position of the parameter index 24 on the control operator 21. (Step S13). At this time, the parameter values in the sound effect parameter list L1 are updated in the same manner.

  Further, the CPU 11 adds an adjustable range display Da and parameter value displays Dp, C2 to the corresponding parameter index 24 (step S14). Further, the CPU 11 adds the adjustable range display Da and the parameter value displays Dp, C2 to the corresponding parameter operator 23 (step S15), and proceeds to step S16. Even when the placement operation of the parameter index 24 is not detected in step S10, the CPU 11 proceeds to step S16.

  In step S <b> 16, the CPU 11 determines whether or not an operation for changing the adjustable range for the parameter operator 23 has been detected. When detecting an operation for changing the adjustable range for the parameter operator 23, the CPU 11 updates the corresponding adjustable range in the control target parameter list L2 (step S17). At this time, the corresponding adjustable range of the sound effect parameter list L1 is also updated. Next, the CPU 11 determines whether or not the operated parameter operator 23 corresponds to the parameter index 24 on the control operator 21 (step S18). If the operated parameter operator 23 does not correspond to the parameter index 24 on the control operator 21, the CPU 11 proceeds to step S21. When the operated parameter operator 23 corresponds to the parameter indicator 24 on the control operator 21, the CPU 11 updates the adjustable range display Da of the corresponding parameter indicator 24 on the control operator 21 (step S19). ), The adjustable range display Da of the corresponding parameter operator 23 is updated (step S20), and the process proceeds to step S21. Even when the change operation of the adjustable range to the parameter operator 23 is not detected in step S16, the CPU 11 proceeds to step S21.

  In step S <b> 21, the CPU 11 determines whether or not a parameter value changing operation on the parameter operator 23 has been detected. When detecting the change operation of the parameter value to the parameter operator 23, the CPU 11 updates the corresponding parameter value in the control target parameter list L2 (step S22). At this time, the corresponding parameter value in the sound effect parameter list L1 is updated in the same manner. Next, the CPU 11 determines whether or not the operated parameter operator 23 corresponds to the parameter index 24 on the control operator 21 (step S23). If the operated parameter operator 23 does not correspond to the parameter index 24 on the control operator 21, the CPU 11 proceeds to step S26. When the operated parameter operator 23 corresponds to the parameter indicator 24 on the control operator 21, the CPU 11 updates the parameter value displays Dp, C2 of the corresponding parameter indicator 24 on the control operator 21 (step S24), the parameter value display Dp, C2 of the corresponding parameter operator 23 is updated (step S25), and the process proceeds to step S26. Even when a parameter value change operation to the parameter operator 23 is not detected in step S21, the CPU 11 proceeds to step S26.

  In step S <b> 26, the CPU 11 determines whether an operation for changing the adjustable range for the parameter index 24 on the control operator 21 has been detected. When detecting the change operation of the adjustable range to the parameter index 24, the CPU 11 updates the corresponding adjustable range in the control target parameter list L2 (step S27). At this time, the corresponding adjustable range of the sound effect parameter list L1 is also updated. Next, the CPU 11 updates the adjustable range display Da of the corresponding parameter indicator 24 on the control operator 21 (step S28), and updates the adjustable range display Da of the corresponding parameter operator 23 (step S29). Return to step S2. Even when the change operation of the adjustable range to the parameter index 24 is not detected in step S26, the CPU 11 returns to step S2.

  Next, referring to FIG. 11, the process at the time of rotation of the control operator in step S5 of FIG. 8 will be described. FIG. 11 is a flowchart showing the process when the control operator rotates. The CPU 11 calculates the current position (X coordinate value, Y coordinate value, and Z coordinate value) of each parameter index 24 on the control operator 21 (step S51). Further, the CPU 11 detects the direction and angle as the rotation information of the control operator 21 (step S52), and calculates the movement trajectory and the arrival position of each parameter index 24 based on the rotation information and the current position of each parameter index 24. (Step S53).

  Next, the CPU 11 determines whether or not there is a parameter index 24 whose Z coordinate value of the reaching position is smaller than the lower limit value (step S54). When there is a parameter index 24 smaller than the lower limit value, the CPU 11 calculates an X coordinate value and a Y coordinate value when the Z coordinate value becomes the lower limit value in the trajectory for the corresponding parameter index 24 (step S55). Further, the CPU 11 changes the arrival position to the calculated X coordinate value, Y coordinate value, and Z coordinate value (step S56), and proceeds to step S57. Thereby, the position of the parameter index 24 is maintained on the outer periphery 21 a of the control operator 21. Even when there is no parameter index 24 smaller than the lower limit value in step S54, the CPU 11 proceeds to step S57.

  In step S57, the CPU 11 moves each parameter index 24 on the control operator 21 from the current position to the arrival position along the calculated trajectory, and changes the display position and the display size. Further, the CPU 11 updates the parameter value in the control target parameter list L2 based on the Z coordinate value of the reaching position for each parameter index 24 on the control operator 21 (step S58). At this time, the parameter values in the sound effect parameter list L1 are updated in the same manner. Thereafter, the CPU 11 updates the parameter value display Dp, C2 of each parameter index 24 on the control operator 21 based on the updated parameter value (step S59), and the parameter value display Dp of the corresponding parameter operator 23. , C2 is updated (step S60).

(6) Effects of the Embodiment In the sound effect data generation device according to the present embodiment, the user can place an arbitrary parameter index 24 at an arbitrary position on the control operator 21, and the control operator An arbitrary parameter index 24 on the control unit 21 can be removed, and the control operator 21 can be easily rotated in an arbitrary direction. Thereby, the user can change any one or a plurality of parameter values continuously and variously with a simple operation. In addition, since a plurality of parameter values can be changed simultaneously, an acoustic effect with a large change in audibility can be obtained.

  In this case, the user can perform the placement operation and the removal operation of the parameter indicator 24 and the rotation operation of the control operator 21 while visually checking the control operator 21 and the parameter indicator 24 displayed on the sound effect parameter adjustment screen 20. Therefore, one or a plurality of parameter values can be adjusted easily and appropriately.

  Further, the user can select the parameter operator 23 displayed in the parameter operator display area 22 and move it as the parameter indicator 24 on the control operator 21. Thereby, a desired parameter index 24 can be arranged on the control operator 21 by a simple movement operation by the user.

  Furthermore, the user can easily change the adjustable range of the parameter value by changing the adjustable range display Da of either one of the parameter operator 23 or the parameter index 24 corresponding to each other on the screen. . Thereby, the parameter value can be adjusted in an appropriate range by the rotation operation of the control operator 21. In this case, since the other adjustable range display Da is also changed in conjunction, the user can simultaneously change the adjustable range display Da of the parameter operator 23 and the parameter index 24 corresponding to each other with a simple operation. .

  Further, the user can easily change the parameter value by changing the parameter value display Dp, C2 of the parameter operator 23 on the screen. This diversifies the parameter value adjustment method.

  Even when the user rotates the control operator 21 too much, the position of the parameter index 24 is maintained on the outer periphery 21a so that the value of the Z coordinate of the parameter index 24 is maintained at 0, and the parameter value is excessively small. Is prevented. Therefore, a natural acoustic effect can be obtained by adjusting the parameter value.

However, the X axis or Y axis corresponds to the reference axis, and the X coordinate of the parameter index 24 The value or the Y coordinate value may correspond to the parameter value. For example, when the X coordinate value of the parameter index 24 corresponds to the parameter value, the parameter value is minimized when the parameter index 24 is positioned at one end (for example, the left end) of the control operator 21 in the X-axis direction. When the index 24 is positioned at the other end (for example, the right end) of the control operator 21 in the X-axis direction, the parameter value becomes maximum.

  In the above embodiment, the parameter indicators 24 are individually arranged on the control operator 21, but a plurality of sound effect parameters may be grouped and arranged on the control operator 21 at once, for example. In the above embodiment, the parameter indicator 24 can move in the upper half of the control operator 21, but the parameter indicator 24 may move in the entire sphere of the control operator 21. In this case, the parameter indicator 24 can also move in the lower half of the hemisphere of the control operator 21.

  In the above embodiment, the position of the parameter index 24 is maintained so that the Z coordinate value of the parameter index 24 does not become smaller than the lower limit value when the control operator 21 is rotated too much. The position of the parameter index 24 may be maintained so that the Z coordinate value of the parameter does not become larger than the upper limit value.
