2. Description of the Related Art Conventionally, a musical sound control device such as a synthesizer or a mixer that can adjust parameters to be used with an operator such as a slider or a rotary volume is known.
In addition, in such a musical tone control device, there are some devices in which a plurality of types of parameters can be adjusted by a common operator.
For example, in the parameter editing apparatus described in Patent Document 1, a parameter of a selected type among a plurality of types of displayed parameters is assigned to an operator in which an operation is detected, and according to the detected operation, The value of the assigned type parameter is changed.

Japanese Patent Laid-Open No. 03-126074

However, when the parameter is adjusted by an operator having polarity (that is, an operator such as a rotary operator or slider having a limited rotation angle), the parameter value is set to the value indicated by the operator within the movable range. Is done. For this reason, when the parameter assigned to the operation element is switched, there may occur a situation in which the parameter setting value (volume etc.) suddenly changes to the value indicated by the operation element.
It should be noted that an operator having no polarity (such as an operator capable of infinite rotation provided with a rotary encoder) cannot be easily adopted because of its high mounting cost.
That is, in the prior art, it has been difficult to realize a function for appropriately operating a plurality of types of parameters with a common operator at a low cost.

  The present invention has been made in view of such a situation, and an object thereof is to realize a function for appropriately operating a plurality of types of parameters with a common operator at a low cost.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[First Embodiment]
[Constitution]
FIG. 1 is a schematic diagram showing an external configuration of a musical tone control apparatus 1 according to an embodiment of the present invention.
FIG. 2 is a block diagram showing a hardware configuration of the musical tone control apparatus 1 according to the embodiment of the present invention.
The musical sound control device 1 is an electronic device that realizes a function of a so-called turntable or DJ mixer, which performs a scratch operation on a musical sound or gives an effect, for example, by electronic processing.
1 and 2, a musical sound control device 1 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a bus 14, an input / output interface 15, and the like. An external interface unit 16, an input unit 17, an output unit 18, a storage unit 19, a communication unit 20, and a drive 21 are provided.

  The CPU 11 executes various processes according to a program recorded in the ROM 12 or a program loaded from the storage unit 19 to the RAM 13.

  The RAM 13 appropriately stores data necessary for the CPU 11 to execute various processes.

  The CPU 11, ROM 12, and RAM 13 are connected to each other via a bus 14. An input / output interface 15 is also connected to the bus 14. An external interface unit 16, an input unit 17, an output unit 18, a storage unit 19, a communication unit 20, and a drive 21 are connected to the input / output interface 15.

  The external interface unit 16 includes an input / output port such as USB (Universal Serial Bus) or MIDI (Musical Instrument Digital Interface), and controls input / output of signals to / from an external device.

The input unit 17 includes a rotary operator (knob), a slider, a button, a pad, and the like, and inputs various types of information according to a user's instruction operation. Specifically, as shown in FIG. 1, the input unit 17 selects a rotary operator 17a for setting various parameters such as the strength and type of the effect, and a selection for selecting a parameter to be assigned to the rotary operator 17a. Button 17b.
FIG. 3 is a schematic diagram showing the function of the rotary operator 17a. FIG. 3A is a diagram showing the rotation range of the rotary operator 17a, and FIG. 3B is a state in which the rotary operator 17a is operated. It is a schematic diagram which shows an example.
As shown in FIG. 3A, the rotary operator 17a is constituted by a rotary operator having a polarity, and has an upper limit and a lower limit of the rotation range. That is, the rotary operator 17a can move within a predetermined operation range. A reference position such as a center position can be set in this operation range. The rotary operator 17a accepts an operation for adjusting the assigned parameter. When an operation is performed on the rotary operator 17a, the position of the rotary operator 17a (the rotation angle from the reference position such as the center position) is input to the CPU 11 and according to the operation amount according to the periodic processing of the rotary operator described later. The parameter is changed. In this embodiment, when the rotary operator 17a is operated, the parameter is increased or decreased according to the angle of rotation of the rotary operator 17a. For example, when the reference position is 0 degrees and the maximum angle of the right operation range is 120 degrees, the parameter can be set to increase by 1 every time the rotary operation element 17a is rotated 5 degrees in the right direction. The parameter increases to 24 when rotated to the maximum angle.

Here, in the present embodiment, as shown in FIG. 3B, when the rotary operation element 17a is operated, the parameter is set for the operation in the right direction in the operation range on the right side (positive side) from the reference position. It is changed and the parameter is not changed for the operation in the left direction. Similarly, in the operation range on the left side (negative side) from the reference position, the parameter is changed for the left direction operation, and the parameter is not changed for the right direction operation. That is, only the parameter change in the direction corresponding to the current operation range is allowed. As a result, when the user rotates the rotary operation element 17a in the predetermined direction from the reference position, returns it to the reference position, and then rotates it again in the predetermined direction, the parameter value corresponding to the integral value of the rotation angle in the predetermined direction. Changed to For example, when the user rotates the rotary operator 17a 90 degrees in the right direction, the parameter increases by 18, and the parameter remains 18 until it is returned to the reference position, and when the user rotates it 60 degrees in the right direction again from the reference position, the parameter Further increases 12 to 30 in total.
However, when the rotary operator 17a is operated across the reference position, the direction corresponding to the current operation range is provided if the rotary operator 17a is not stopped at the reference position for a certain time (a threshold time Tth described later) or longer. Changes to parameters are restricted. On the other hand, when the rotary operator 17a is stopped for a certain period of time at the reference position, the parameter is changed in the direction corresponding to the current operation range according to the operation as described above. Thereby, even when the user unintentionally operates beyond the reference position when returning the rotary operation element 17a to the reference position, it is possible to prevent the parameters from being changed unnecessarily.

  The selection button 17b receives an operation for selecting a parameter to be assigned to the rotary operator 17a from among a plurality of types of parameters. When an operation is performed on the selection button 17b, the type of the selected parameter is input to the CPU 11, and the parameter to be adjusted is switched by the CPU 11 according to the periodic processing of the rotary operator. In the present embodiment, as parameters to be adjusted, for example, volume, tempo, selection of rhythms and timbres such as rhythm patterns and tone banks, designation of sequencer track numbers and channel numbers, and effects indicating the types of effects Various parameters such as number, effect duration and effect depth, note number indicating the pitch and order of notes, data storage destination number, and the like can be designated.

The output unit 18 includes a display, a speaker, and the like, and outputs images and sounds. For example, the display of the output unit 18 displays the types and values of parameters to be adjusted by the rotary operator 17a. In addition, from the speaker of the output unit 18, a musical sound or the like to which an effect has been applied is output.
The storage unit 19 is configured by a hard disk or a DRAM (Dynamic Random Access Memory), and stores various data used in the musical sound control apparatus 1 such as a filter for realizing an effect, rhythm or tempo data, and the like.
The communication unit 20 controls communication with other devices (not shown) via a network including the Internet.

  A removable medium 31 composed of a magnetic disk, an optical disk, a magneto-optical disk, a semiconductor memory, or the like is appropriately attached to the drive 21. The program read from the removable medium 31 by the drive 21 is installed in the storage unit 19 as necessary. The removable medium 31 can also store various data stored in the storage unit 19 in the same manner as the storage unit 19.

[Operation]
Next, the operation of the musical tone control apparatus 1 will be described.
[Main flow]
First, a main flow executed by the CPU 11 will be described with reference to FIG.
FIG. 4 is a flowchart for explaining the flow of the main flow executed by the CPU 11.
The main flow is activated when the musical sound control device 1 is powered on.

In step S <b> 1, the CPU 11 performs an initialization process for the tone control device 1. Specifically, the CPU 11 initializes the RAM 13, the external interface unit 16, and the like.
In step S2, the CPU 11 executes basic processing (processing including confirmation of various switches, control of sound generation, recording of musical sound, etc.) of the musical sound control device 1.

  In step S3, the CPU 11 assigns a parameter to be adjusted in the rotary operator 17a. At this time, the CPU 11 assigns the parameter previously set as the adjustment target to the rotary operator 17a, or assigns the parameter selected by the user to the rotary operator 17a.

In step S <b> 4, the CPU 11 executes a periodic process of the rotary operator (see FIG. 5).
In step S5, the CPU 11 determines whether or not an operation for ending the operation of the musical tone control device 1 has been performed. For example, the CPU 11 determines whether or not an operation for turning off the power of the musical tone control device 1 has been performed.
When the operation for ending the operation of the musical tone control device 1 is not performed, NO is determined in step S5, and the process proceeds to step S2.
On the other hand, when an operation for ending the operation of the musical tone control device 1 is performed, it is determined as YES in Step S5, and the main flow ends.

[Rotating operator cyclic processing]
Next, the periodic processing of the rotary operator that is executed in step S4 of the main flow will be described.
FIG. 5 is a flowchart for explaining the flow of periodic processing of the rotary operator.
In step S11, the CPU 11 acquires the current position (rotation angle from the reference position) of the rotary operator 17a.
In step S12, the CPU 11 determines whether or not the current position of the rotary operator 17a is the reference position.
If the current position of the rotary operator 17a is the reference position, YES is determined in step S12, and the process proceeds to step S13.
On the other hand, when the current position of the rotary operator 17a is not the reference position, NO is determined in step S12, and the process proceeds to step S17.

In step S13, the CPU 11 determines whether or not the previous position of the rotary operator 17a is the reference position.
If the previous position of the rotary operator 17a is not the reference position, NO is determined in step S13, and the process proceeds to step S14.
On the other hand, when the previous position of the rotary operator 17a is the reference position, it is determined as YES in Step S13, and the process proceeds to Step S15.

In step S <b> 14, the CPU 11 sets the current time in the variable T. The variable T is used for measuring the elapsed time.
In step S15, the CPU 11 determines whether or not the difference between the current time and the time set in the variable T is equal to or greater than a preset threshold time Tth.
If the difference between the current time and the time set in the variable T is not equal to or greater than the preset threshold time Tth, NO is determined in step S15, and the process returns to the main flow.
On the other hand, if the difference between the current time and the time set in the variable T is greater than or equal to the preset threshold time Tth, YES is determined in step S15, and the process proceeds to step S16.

In step S16, the CPU 11 sets zero to the variable F. A variable F indicates a parameter change state allowed for the operation of the rotary operator 17a. Specifically, when the variable F is zero, the parameter is allowed to both increase and decrease depending on the current operating range of the rotary operator 17a. Further, when the variable F is 1, only an increase in the parameter is allowed. On the other hand, when the variable F is −1, only a decrease in the parameter is allowed.
After step S16, the process returns to the main flow.

In step S17, the CPU 11 determines whether or not the current position of the rotary operator 17a has changed in a direction away from the reference position from the previous position.
If the current position of the rotary operator 17a has not changed in the direction away from the reference position from the previous position, NO is determined in step S17, and the process returns to the main flow. This is because when the current position of the rotary operation element 17a is in the operation range on the right side (positive side) from the reference position and operated in the left direction, the current position of the rotary operation element 17a is on the left side (from the reference position). It means that the parameter is not increased or decreased when operated in the right direction in the negative range.
On the other hand, when the current position of the rotary operator 17a has changed in the direction away from the reference position from the previous position, YES is determined in step S17, and the process proceeds to step S18.

In step S18, the CPU 11 determines whether or not the current position of the rotary operator 17a is on the right side (positive side) from the reference position.
If the current position of the rotary operator 17a is on the right side (positive side) from the reference position, YES is determined in step S18, and the process proceeds to step S19.
On the other hand, if the current position of the rotary operator 17a is on the left side (negative side) from the reference position, NO is determined in step S18, and the process proceeds to step S23.

In step S19, the CPU 11 determines whether or not the variable F is zero.
When the variable F is zero, it determines with YES in step S19, and a process transfers to step S20.
On the other hand, when the variable F is not zero, it is determined as NO in Step S19, and the process proceeds to Step S21.

In step S <b> 20, the CPU 11 sets 1 to the variable F.
In step S21, the CPU 11 determines whether or not the variable F is greater than zero.
When the variable F is larger than zero, it determines with YES in step S21, and a process transfers to step S22.
On the other hand, when the variable F is less than or equal to zero, it is determined as NO in Step S21, and the process returns to the main flow.

In step S22, the CPU 11 increases or decreases the value of the parameter according to the difference between the current position of the rotary operator 17a and the previous position. That is, when the current position of the rotary operation element 17a is in the operation range on the right side (positive side) from the reference position, the processing of the value of the variable F in the above-described step S19 to step S21 allows the operation in the right direction. Only the parameters will be changed. On the other hand, in the operation range on the left side (negative side) from the reference position, the parameter is changed only for the operation in the left direction by processing the value of the variable F in steps S23 to S25 described later. .
After step S22, the process returns to the main flow.

In step S23, the CPU 11 determines whether or not the variable F is zero.
When the variable F is zero, it determines with YES in step S23, and a process transfers to step S24.
On the other hand, when the variable F is not zero, it is determined as NO in Step S23, and the process proceeds to Step S25.

In step S <b> 24, the CPU 11 sets −1 to the variable F.
In step S25, the CPU 11 determines whether or not the variable F is smaller than zero.
When the variable F is smaller than zero, it determines with YES in step S25, and a process transfers to step S22.
On the other hand, if the variable F is greater than or equal to zero, NO is determined in step S25, and the process returns to the main flow.

As a result of such processing, in the musical tone control device 1, when the rotary operation element 17a is operated, the parameter is changed with respect to the operation in the right direction in the operation range on the right side (positive side) from the reference position. The parameter is not changed for leftward operation. Further, in the operation range on the left side (negative side) from the reference position, the parameter is changed for the left direction operation, and the parameter is not changed for the right direction operation.
As a result, when the user rotates the rotary operation element 17a in the predetermined direction from the reference position, returns it to the reference position, and then rotates it again in the predetermined direction, the parameter value corresponding to the integral value of the rotation angle in the predetermined direction. Changed to
Therefore, even when the parameter to be adjusted is switched, the parameter can be appropriately operated by the rotary operation element 17a.
Therefore, it is possible to realize a function for appropriately operating a plurality of types of parameters with a common operator at a low cost.
Further, in the musical tone control device 1, when the rotation operator 17a is operated and then stopped at the reference position for the threshold time Tth or longer, either the right or left operation of the rotation operator 17a is performed. In contrast, the parameter is increased and decreased in the direction corresponding to the current operation range. On the other hand, after the rotation operator 17a is operated, when the stop for the threshold time Tth or more is not performed at the reference position, the variable F is held at the previous value, so that the operation of the rotation operator 17a is performed. On the other hand, only the parameter change according to the operation in the direction allowed by the variable F is valid, and the parameter change according to the operation in the reverse direction is limited. That is, even when the rotary operator 17a is operated rightward (positive side), increase of the parameter is not allowed unless the value of the conventional variable F is F> 0 (step S21: NO). . On the other hand, even if the rotary operator 17a is operated in the left direction (negative side), the parameter is not allowed to decrease unless the value of the variable F from the past is F <0 (step S25: NO). ).
Thereby, even when the user unintentionally operates beyond the reference position when returning the rotary operation element 17a to the reference position, it is possible to prevent the parameters from being changed unnecessarily.

[Second Embodiment]
Next, a second embodiment of the present invention will be described.
The musical tone control apparatus 1 according to the second embodiment is different from the main flow of FIG. 4 in the first embodiment in the content of the periodic processing of the rotary operator.
Therefore, hereinafter, the periodic processing of the rotary operator, which is a different part from the first embodiment, will be described.

FIG. 6 is a flowchart for explaining the flow of the periodic processing of the rotary operator in the second embodiment.
In FIG. 6, the process of step S11 and step S17-step S25 is the same as that of FIG. 5 in 1st Embodiment.
In step S112, the CPU 11 determines whether or not the current position of the rotary operator 17a is the same as the previous position.
If the current position of the rotary operator 17a is not the same as the previous position, NO is determined in step S112, and the process proceeds to step S113.
On the other hand, if the current position of the rotary operator 17a is the same as the previous position, YES is determined in step S112, and the process proceeds to step S114.

In step S113, the CPU 11 sets the current time in the variable T.
After step S113, the process proceeds to step S17.
In step S114, the CPU 11 determines whether or not the difference between the current time and the time set in the variable T is equal to or greater than a preset threshold time Tth.
If the difference between the current time and the time set in the variable T is not greater than or equal to the preset threshold time Tth, NO is determined in step S114, and the process returns to the main flow.
On the other hand, if the difference between the current time and the time set in the variable T is equal to or greater than the preset threshold time Tth, YES is determined in step S114, and the process proceeds to step S115.
In step S115, the CPU 11 sets a variable F to zero.
After step S115, the process returns to the main flow.

As a result of such processing, in the musical tone control device 1, when the rotary operation element 17a is operated, the parameter is changed with respect to the operation in the right direction in the operation range on the right side (positive side) from the reference position. The parameter is not changed for leftward operation. Further, in the operation range on the left side (negative side) from the reference position, the parameter is changed for the left direction operation, and the parameter is not changed for the right direction operation. Therefore, if the rotary operator is operated in a certain direction from the reference position and then returned to the reference position again, the parameter is maintained while returning to the reference position (while operating in the direction approaching the reference position). Is not changed. And if you operate in the direction away from the reference position again before reaching the reference position (in the operation range on the right side (positive side) from the reference position, in the right direction operation, in the operation range on the left side (negative side) from the reference position In the left direction), the parameter is changed again. In the present embodiment, when the rotary operation element 17a is operated and then stopped at an arbitrary position for a predetermined time (threshold time Tth) or more, 0 is set to the variable F. Then, after returning from the above-mentioned arbitrary position to the reference position and further operating beyond the reference position to the opposite side, the parameter is changed in the reverse direction from the time when the reference position is exceeded.
That is, in the first embodiment, the change of the parameter is not limited to the operation of the rotary operation element 17a by stopping at the reference position for the threshold time Tth or longer. Even if it is not limited to the reference position, by stopping at any position for the threshold time Tth or longer, the operation of the rotary operator 17a is operated in the direction opposite to the current operation range beyond the reference position. Even in the case of the change, the parameter change is not restricted.
As a result, the user can stop the rotary operation element 17a not only at the reference position but also at an arbitrary position so that the change of the parameter when the user subsequently operates in the opposite direction beyond the reference position is not restricted. it can.

In the above-described embodiment, the center position of the rotation range is given as an example as the reference position of the rotary operation element 17a, but is not limited thereto. For example, the reference position of the rotary operator 17a can be the upper limit or the lower limit of the rotation range. In this case, the value of the parameter only changes or only decreases according to the operation of the rotary operator 17a.
Moreover, although the case where this invention was applied to the rotary operation element 17a was mentioned as an example in the above-mentioned embodiment, it is not restricted to this. For example, the present invention may be applied to an operator having another shape such as a slider.

Further, in the above-described embodiment, the case where the parameter is increased or decreased according to the angle of the rotation of the rotary operator 17a has been described as an example. On the other hand, the parameter may be increased or decreased according to the angular velocity at which the rotary operator 17a is rotated. For example, when the rotary operator 17a is rotated 15 degrees to the right from the reference position, the parameter is increased by 15 when rotated at an angular velocity of 5 degrees / second, and rotated at an angular velocity of 10 degrees / second. It is possible to increase the parameter by 30 or the like.
Further, the parameter may be increased or decreased according to the position in the rotation range of the rotary operator 17a. For example, when the rotary operator 17a is rotated 5 degrees to the right from the reference position, the parameter is increased by 1, and when the rotary operator 17a is rotated 5 degrees from the position of 50 degrees to the right from the reference position. It is possible to increase the parameter by 10 or the like.

Further, in the above-described embodiment, the configuration of the rotary operation element 17a can have a center click function (function of increasing the rotation resistance at the reference position), and the rotation can be easily stopped at the reference position.
In the above embodiment, when determining the reference position, a range having a certain width including the reference position (for example, a range of 10 degrees on each of the positive side and the negative side) is regarded as the reference position. In other words, so-called “play” can be provided, and the rotary operation member 17a can be easily stopped at the reference position.
Furthermore, the so-called “play” range of the reference position can be changed according to the situation. For example, the reference position in the state where the variable F is other than zero (when the change of the parameter is limited) than the range of “play” of the reference position in the state where the variable F is zero (the state where there is no restriction on the parameter change) The range of “play” can be increased. Thereby, when the user performs an operation of returning the rotary operation element 17a to the reference position, the range determined as the reference position can be expanded, and the user intends to return the rotation operation element 17a to the reference position appropriately. It can be reflected.

The musical tone control apparatus 1 configured as described above includes a rotary operator 17a and a CPU 11.
The rotary operator 17a is movable within a predetermined operation range including a reference position.
In response to an operation in one direction of the rotary operator 17a when the rotary operator 17a is operated in a range on the one direction side from the reference position in the operation range, the CPU 11 rotates the rotary operator 17a. The parameter value assigned to 17a is changed, and control is performed so as not to change the parameter value for an operation in another direction different from the one direction.
As a result, when the rotary operator 17a is rotated in the predetermined direction from the reference position, returned to the reference position and then rotated in the predetermined direction again, the parameter value is changed according to the integral value of the rotation angle in the predetermined direction. Is done.
Therefore, even when the parameter to be adjusted is switched, the parameter can be appropriately operated by the rotary operation element 17a.
Therefore, it is possible to realize a function for appropriately operating a plurality of types of parameters with a common operator at a low cost.

In addition, when the rotation operator 17a has not been stopped at the reference position for a preset time with respect to the operation straddling the reference position of the rotation operator 17a, the CPU 11 opposes the rotation operator 17a beyond the reference position. Even if operated on the side, control is performed so that the parameter value does not change.
Thereby, when returning the operation element to the reference position, even when the operation element is unintentionally operated beyond the reference position, it is possible to prevent the parameter from being changed unnecessarily.

Further, the CPU 11 is set not only at the reference position but also at an arbitrary position after the rotation operator 17a is operated in either direction when an operation across the reference position is performed by the rotation operator 17a. When the operation is stopped for more than the time, even if the operation is performed in the direction opposite to the current operation range after exceeding the reference position, the parameter change is not limited.
As a result, the user can stop the rotary operation element 17a not only at the reference position but also at an arbitrary position so that the change of the parameter when the user subsequently operates in the opposite direction beyond the reference position is not restricted. it can.

Further, the CPU 11 determines that the rotary operation element 17a has been stopped at the reference position when it is stopped within a preset range including the reference position.
As a result, it is possible to easily perform the operation of stopping the operation element at the reference position.

Further, the CPU 11 changes the size of a preset range including the reference position according to the operation state of the rotary operator 17a.
Thereby, when a user performs operation which returns an operation element to a standard position, the range judged as a standard position can be expanded.
Therefore, it is possible to accurately reflect the intention of the user to return the operation element to the reference position.

The electronic musical instrument to which the present invention is applied outputs a musical sound controlled by the musical sound control device 1.
