Generally, the adjustable range of each sound effect parameter is predetermined. When the values of a plurality of sound effect parameters are adjusted within such a certain range, changes in the sound such as noise may occur depending on the combination of the values of the sound effect parameters. If the user is familiar with the relationship between multiple sound effect parameters, it is possible to adjust the value of each sound effect parameter within an appropriate range, but for the average user, such adjustment is possible. Difficult to do.

An object of the present invention is to provide a sound effect control device, a sound effect control program, and a sound effect control method capable of appropriately controlling a sound effect with a simple operation without requiring special knowledge. ..

A parameter output means for outputting the value of each determined parameter is provided, and the parameter value determination means determines whether or not to link a plurality of types of parameters based on the acquired sound effect information.

In this sound effect control device, sound effect information corresponding to the selected sound effect type is acquired, and it is determined whether or not to link a plurality of types of sound effect parameters based on the sound effect information. In this case, for the sound effect type in which changes in the sound that the user does not intend are unlikely to occur, each sound effect parameter is adjusted independently without interlocking multiple types of sound effect parameters, and the sound effect is controlled with a high degree of freedom. can do. In this way, various sound effects can be appropriately controlled by switching the presence / absence of interlocking of sound effect parameters according to the sound effect type.

Therefore, for an acoustic effect in which a change in sound that is not intended by the user is unlikely to occur, the acoustic effect can be controlled with a high degree of freedom by independently adjusting each of a plurality of types of parameters.

When a plurality of types of parameters are linked when the operator in which the operation is detected is set as the reference operator, the parameter value determining means determines the parameter corresponding to the reference operator based on the detected operation. The value may be determined.

When a plurality of types of parameters are linked, the parameter value determining means determines an adjustable range of parameters corresponding to other controls having a lower priority than the reference operator based on the determined parameter values. May be good.

In this case, when the other controls are manipulated, the values of the parameters corresponding to the other controls change only within the appropriate range depending on the values of the parameters corresponding to the reference controls. Therefore, the relationship between the value of the parameter corresponding to the reference operator and the value of the parameter corresponding to the other operator is properly maintained. In this way, by appropriately maintaining the relationship between the values of the parameters of the plurality of controls, it is possible to prevent unintended changes in sound such as noise from occurring. Therefore, the user can appropriately control the acoustic effect by a simple operation without causing an audible discomfort without requiring special knowledge.

The parameter value determining means corresponds to another operator having a lower priority than the reference operator when the operator in which the operation is detected is set as the reference operator and multiple types of parameters are not linked. The adjustable range of the parameters may be a predetermined reference range.

In this case, for an acoustic effect in which a change in sound that is not intended by the user is unlikely to occur, the acoustic effect can be controlled with a high degree of freedom by independently adjusting each of a plurality of types of parameters.

Multiple types of sound effect parameters are classified into multiple types of sound effects. The sound effect types include, for example, "Low Pass Filter", "Delay", "Oscillator", "LFO" (low frequency oscillator), "Distortion", and rotary. There are speakers etc. The types of sound effect parameters corresponding to the "Low Pass Filter" include "Cutoff Frequency", "Resonance", and "Dry / Wet" (volume balance between the original sound and the effect sound). be. Types of sound effect parameters corresponding to "Delay" include "Delay Time" (delay time), "Feedback" (feedback amount), "Pan" (sound localization), and the like.

The user selects one sound effect type by operating the setting operation unit 4. Based on the sound effect information described below, the sound effect parameters corresponding to the selected sound effect type are assigned to each controller 7.

(2) Functional Configuration of Sound Effect Control Device 100 FIG. 2 is a diagram for explaining a functional configuration of the sound effect control device 100 according to the embodiment of the present invention. As shown in FIG. 2, in the present embodiment, three controls 7 including a rotary encoder are provided. Hereinafter, in order to distinguish the three controls 7, the three controls 7 are referred to as controls 7A, 7B, and 7C, respectively. Each of the operators 7A to 7C has a convex reference portion ST. Further, an arcuate scale SC is attached so as to surround the outer periphery of each of the controls 7A to 7C. One end SCa of the scale SC corresponds to the lower limit value of the adjustable range of the parameter value corresponding to each operator (hereinafter referred to as the operation range), and the other end SCb corresponds to the upper limit value of the operation range. The user rotates the operators 7A to 7C to align each reference portion ST with an arbitrary position between one end SCa and the other end SCb of the scale SC. Hereinafter, the position of the scale SC pointed to by the reference unit ST of the controls 7A to 7C is referred to as a scale position.

By executing the sound effect control program stored in the ROM 10 or the storage device 13, the CPU 11 of FIG. 1 executes the reference controller setting unit 21, the operation detection unit 22, the selection unit 23, the sound effect information acquisition unit 24, and the parameter type acquisition. The functions of the unit 26, the parameter value determination unit 27, and the parameter output unit 28 are realized. These functional parts may be realized by hardware such as an electronic circuit.

The reference operator setting unit 21 sets one of the operators 7A to 7C as the “reference operator”. The details of the "reference operator" will be described later. The operation detection unit 22 detects the operations of the setting operation unit 4 and the operators 7A to 7C in FIG. 1. Further, the operation detection unit 22 detects the states of the operators 7A to 7C. In this example, the states of the controls 7A to 7C correspond to the scale positions of the controls 7A to 7C. The selection unit 23 accepts the selection of the sound effect type based on the operation of the setting operation unit 4 detected by the operation detection unit 22. The sound effect information acquisition unit 24 acquires sound effect information corresponding to the selected sound effect type. For example, sound effect information corresponding to all sound effect types is stored in advance in the storage device 13 of FIG. In that case, the sound effect information acquisition unit 24 reads the corresponding sound effect information from the storage device 13. The sound effect information may be acquired from the external storage device 15 by the communication I / F 14, or may be acquired via the communication network.

The parameter type acquisition unit 26 acquires a plurality of types of sound effect parameters (hereinafter, referred to as parameter types) corresponding to the operators 7A to 7C, respectively, based on the acquired sound effect information. The parameter value determination unit 27 determines a plurality of parameter values corresponding to the operators 7A to 7C, respectively. In this case, the parameter value determination unit 27 determines whether or not to link a plurality of types of sound effect parameters based on the acquired sound effect information. When a plurality of types of sound effect parameters are linked, the parameter value determination unit 27 determines the operation range of the parameter values corresponding to the other controls 7 based on the parameter values corresponding to the “reference operator”.

The parameter output unit 28 outputs the parameter types and parameter values corresponding to the controls 7A to 7C as sound effect data. The acoustic effect data output from the parameter output unit 28 is given to the effect circuit 17 of FIG. In the effect circuit 17, the parameter value stored in the register corresponding to the given parameter type is updated to the given parameter value.

(3) Sound effect information FIG. 3 is a diagram for explaining an example of sound effect information. FIG. 3 shows sound effect information corresponding to “Low Pass Filter” and “Delay”, which are examples of sound effect types. Further, in FIG. 3, the sound effect parameter corresponding to the operator 7A is represented as “parameter A”, the sound effect parameter corresponding to the operator 7B is represented as “parameter B”, and the sound effect corresponding to the operator 7C is represented. The effect parameter is represented as "parameter C". Priority is set for the controls 7A to 7C. In the example of FIG. 3, the priorities of the controls 7A, 7B, and 7C are set to the first, second, and third, respectively. The priority may be fixed or changeable. Further, the priorities of the controls 7A to 7C may be set for each sound effect type.

Each sound effect information includes parameter types and reference ranges of parameters A to C. The reference range is a predetermined reference range for each parameter type, and is, for example, the maximum operation range. For example, the sound effect information corresponding to "Low Pass Filter" includes "Cutoff Frequency", "Resonance" and "Dry / wet" as parameter types, and "10Hz to 20kHz" and "-" as reference ranges for these. Includes "20 dB to + 20 dB" and "0% to 100%".

In addition, each sound effect information includes interlocking information indicating whether or not a plurality of acoustic effect parameters are interlocked. In the following description, with respect to the two sound effect parameters corresponding to the n (n is a positive integer) position operator 7 and the n + 1 position operator 7, the sound effect parameter corresponding to the n-position operator 7 is ranked higher. The sound effect parameter corresponding to the n + 1th operator 7 is called a lower parameter. When the interlocking information is on, the operation range of the lower parameter changes depending on the value of the upper parameter. In this example, the operating range of parameter B depends on the value of parameter A, and the operating range of parameter C depends on the value of parameter B. The details of the interlocking of sound effect parameters will be described later. When interlocking information is off, the operating range of each sound effect parameter does not depend on the values of other parameters.

The sound effect information further includes a change mode of the operation range of the lower parameter when the interlocking information is on. In the example of FIG. 3, the acoustic effect information corresponding to the “Low Pass Filter” includes “Pattern A” and “Pattern B” as the variation modes of the parameters B and C. The mode of change in the operating range is represented by, for example, a map, a table or a mathematical formula. In this example, the on / off of the interlocking information is predetermined for each sound effect type, but the user may be able to switch the on / off of the interlocking information.

(4) Interlocking of sound effect parameters The interlocking of a plurality of sound effect parameters will be specifically described. Here, an example in which the sound effect type is “Low Pass Filter” and the operation range of parameter B (“Resonance”) changes depending on the value of parameter A (“Cutoff Frequency”) will be described.

FIG. 4 is a diagram showing the relationship between the states of the controls 7A and 7B and the values of the parameters A and B. FIG. 5 is a diagram showing an example of a change mode of the operation range of the parameter B. The example of FIG. 5 corresponds to the pattern A of FIG. In FIG. 5, the horizontal axis represents the value of the parameter A, and the vertical axis represents the upper limit value of the operation range of the parameter B. The straight line L1 represents the relationship between the value of the parameter A and the upper limit value of the operation range of the parameter B. Specifically, as the value of the parameter A increases, the upper limit of the operation range of the parameter B decreases linearly. In this example, the operation range of the parameter B changes so that the absolute value of the lower limit value becomes equal to the upper limit value.

The operating range of the parameter A corresponding to the operator 7A having the highest priority coincides with the reference range. Therefore, in the examples of FIGS. 4 (a) and 4 (b), the operating range of the parameter A is “10 Hz to 20 kHz”. Within the operating range of the parameter A, the value of the parameter A is determined based on the state of the actuator 7A. In the example of FIG. 4A, the value of the parameter A is “TA1”, and in the example of FIG. 4B, the value of the parameter A is “TA2”.

As shown in FIG. 5, when the value of parameter A is "TA1", the upper limit of the operation range of parameter B is "+ TB1r", and when the value of parameter A is "TA2", the operation of parameter B is performed. The upper limit of the range is "+ TB2r". Therefore, in the example of FIG. 4A, the operation range of the parameter B is "-TB1r to + TB1r", and in the example of FIG. 4B, the operation range of the parameter B is "-TB2r to + TB2r". ..

Within the operating range of parameter B, the value of parameter B is determined based on the state of the operator 7B. In the example of FIG. 4A and the example of FIG. 4B, the states of the controls 7B are the same as each other. However, the operating ranges of parameter B are different from each other. Therefore, the value of the parameter B is also different. In the example of FIG. 4A, the value of the parameter B is “TB1”, and in the example of FIG. 4B, the value of the parameter B is “TB2”.

In the example of FIG. 5, when the value of the parameter A is the lower limit value “10 Hz”, the upper limit value of the operation range of the parameter B is “+ TB3r”. “+ TB3r” is, for example, the upper limit value “20 (dB)” of the reference range of the parameter B.

In this way, the operating range of the lower parameter is determined based on the value of the higher parameter. In the examples of FIGS. 4 and 5, the operating range of the parameter B is determined based on the value of the parameter A, and similarly, the operating range of the parameter C is determined based on the value of the parameter B.

In the example of FIG. 5, the lower limit value and the upper limit value of the operation range of the lower parameter (“Resonance”) change depending on the value of the upper parameter (“Cutoff Frequency”), but the operation of the lower parameter is performed. Only one of the lower and upper limits of the range may change. For example, when “Dry / Wet” in FIG. 3 is a lower parameter, the lower limit of the operation range of the lower parameter is fixed to the lower limit value “0%” of the reference range, and the upper parameter (“Resonance”). Depending on the value of, only the upper limit of the operating range of the lower parameters may change.

Further, in the example of FIG. 5, since the upper limit value of the operation range of the parameter B is equal to the absolute value of the lower limit value, the lower limit value is also uniquely determined by determining the upper limit value of the operation range based on the straight line L1. However, the upper limit value and the lower limit value of the operation range may be determined independently. For example, a straight line representing the value of the upper parameter and the upper limit of the operation range of the lower parameter, and a straight line representing the value of the upper parameter and the lower limit of the operation range of the lower parameter may be set separately. ..

FIG. 6 is a diagram showing another example of the change mode of the operation range. In FIGS. 6A to 6C, the horizontal axis represents the value of the upper parameter, and the vertical axis represents the upper limit value or the lower limit value of the operation range of the lower parameter. The points that the examples of FIGS. 6A to 6C are different from the example of FIG. 5 will be described. In the examples of FIGS. 6A and 6B, the relationship between the value of the upper parameter and the operation range of the lower parameter is represented by curves L1a and L1b instead of a straight line. In the example of FIG. 6C, as represented by the straight line L1c, the operation range of the lower parameter increases linearly with the increase of the upper parameter. Depending on the combination of the types of upper and lower parameters, the operating range of the lower parameters changes in such various aspects. In the example of FIG. 3, the change mode of the operation range of the lower parameter is predetermined, but the user may be able to select the change mode to be used from a plurality of change modes stored in advance. Alternatively, the user may arbitrarily set the change mode.

(5) Sound effect control processing FIGS. 7 and 8 are flowcharts showing an example of sound effect control processing by each functional unit of FIG. 2. The sound effect control process of FIG. 7 is performed by the CPU 11 of FIG. 1 executing the sound effect control program stored in the ROM 10 or the storage device 13.

First, the reference operator setting unit 21 of FIG. 2 sets the operator 7 having the highest priority as the “reference operator” (step S1). Next, the sound effect information acquisition unit 24 secures an area in the storage device 13 for temporarily storing the “current parameter value” and the “current range” of each operator 7 (step S2). Next, the CPU 11 determines whether or not the operation for ending the sound effect control process is detected by the operation detection unit 22 (step S3). The operation for ending is, for example, an operation for making a setting other than the sound effect. When the operation for termination is detected, the CPU 11 terminates the sound effect control process.

If the operation for termination has not been detected, the selection unit 23 determines whether or not the operation for selecting the sound effect type has been detected by the operation detection unit 22 (step S4). When the operation for selection is detected, the sound effect information acquisition unit 24 acquires the sound effect information corresponding to the selected sound effect type (step S5).

Next, the parameter type acquisition unit 26 acquires the parameter type represented by the acquired acoustic effect information for each operator 7 (step S6). Next, the parameter value determination unit 27 determines whether or not to interlock the acquired plurality of types of acoustic effect parameters based on the interlocking information of the acquired acoustic effect information (step S7). When a plurality of types of sound effect parameters are not linked, the parameter value determination unit 27 is based on the reference range represented by the acquired sound effect information and the state of each operator 7 detected by the operation detection unit 22. The parameter value corresponding to each operator 7 is calculated (step S8). In this case, the operation range of the sound effect parameter corresponding to each operator 7 is set to the reference range represented by the sound effect information. Next, the parameter output unit 28 outputs the acquired parameter type and the calculated parameter value as sound effect data (step S9).

When a plurality of types of sound effect parameters are linked in step S7, the reference controller setting unit 21 and the parameter value determination unit 27 perform parameter update processing (step S10), and the “current parameter value” stored in the storage device 13 is stored. And "Current Range" are updated. The details of the parameter update process will be described later. Next, the parameter output unit 28 outputs the acquired parameter type and the updated "current parameter value" as sound effect data (step S11).

If the operation for selecting the sound effect type is not detected in step S4, if step S9 is executed, or if step S11 is executed, the CPU 11 detects the operation of any of the controls 7. It is determined whether or not it has been detected by the unit 22 (step S12 in FIG. 8). If the operation of any of the controls 7 is not detected, the CPU 11 returns to step S3. When the operation of any of the controls 7 is detected, the parameter value determination unit 27 determines whether or not to link a plurality of types of sound effect parameters based on the linked information of the acquired sound effect information. (Step S13).

When step S9 or step S11 is executed, the determination in step S13 is performed based on the sound effect information acquired in step S5. On the other hand, if the operation for selecting the sound effect type is not selected in step S4 immediately after the start of the sound effect control process, the determination in step S13 is made based on the sound effect information acquired in advance. Is done. For example, at the start of the sound effect control process, the sound effect information corresponding to the default sound effect type or the sound effect information corresponding to the sound effect type selected at the end of the previous sound effect control process is acquired, and the sound effect information is acquired. The determination in step S13 is performed based on the sound effect information.

When a plurality of types of sound effect parameters are not linked, the parameter value determination unit 27 determines the parameter value corresponding to each operator 7 based on the reference range and the state of each operator 7 as in step S8 of FIG. Calculate (step S14). Next, the parameter output unit 28 outputs the parameter type acquired in step S6 and the parameter value calculated in step S14 as sound effect data (step S15), and returns to step S3 in FIG. 7.

When linking a plurality of types of sound effect parameters in step S13, the reference operator setting unit 21 sets the operator 7 in which the operation is detected as the “reference operator” (step S16). Next, the reference controller setting unit 21 and the parameter value determination unit 27 perform the parameter update process described later (step S17), and update the “current parameter value” and the “current range” stored in the storage device 13. do. Next, the parameter output unit 28 outputs the parameter type acquired in step S6 and the updated "current parameter value" as sound effect data (step S18), and returns to step S3 in FIG. 7.

The parameter update process of step S10 of FIG. 7 and step S17 of FIG. 8 will be described. FIG. 9 is a flowchart showing an example of the parameter update process. First, the parameter value determination unit 27 calculates the parameter value corresponding to the “reference operator” based on the states of the “current range” and the “reference operator” corresponding to the “reference operator” (step S21). ). At the start of the parameter update process in step S10, the "reference operator" is the operator 7 having the highest priority, and the "current range" is the reference corresponding to the operator 7 having the first priority. It is a range. At the start of the parameter update process in step S17, the "reference operator" is the operator 7 whose operation was detected in the immediately preceding step S12, and the "current range" was updated in the previous parameter update process. The operation range. The method of calculating the parameter value is the same as the method of calculating the parameter value in step S8 of FIG. 7 and step S14 of FIG. 8, except that the “current range” is used instead of the reference range.

Next, the parameter value determination unit 27 updates the "current parameter value" corresponding to the "reference controller" to the parameter value calculated in step S21 (step S22). Next, the parameter value determination unit 27 determines whether or not the priority of the “reference operator” is the lowest (step S23). If the priority of the "reference operator" is not the lowest, the parameter value determination unit 27 uses the "current parameter value" corresponding to the "reference operator" and the operation range represented by the acquired acoustic effect information. Based on the change mode of the above, the operation range of the operator 7 (hereinafter, referred to as “lower operator”) having a priority one lower than that of the “reference operator” is calculated (step S24). In this case, the sound effect parameter corresponding to the "reference manipulator" corresponds to the upper parameter, and the sound effect parameter corresponding to the "lower manipulator" corresponds to the lower parameter. In step S24, as in the examples of FIGS. 4 and 5, the operation range of the lower parameter is determined based on the value of the upper parameter.

Next, the parameter value determination unit 27 updates the "current range" corresponding to the "lower control element" to the operation range calculated in step S24 (step S25). Next, the parameter value determination unit 27 is based on the states of the "current range" and the "subordinate operator" corresponding to the "subordinate operator", and the parameter corresponding to the "subordinate operator" is the same as in step S21. Calculate the value (step S26).

Next, the parameter value determination unit 27 updates the "current parameter value" corresponding to the "lower-level operator" to the parameter value calculated in step S26 (step S27). Next, the reference operator setting unit 21 sets the “subordinate operator” to the “reference operator” (step S28), and returns to step S23.

In step S23, when the priority of the "reference operator" is the lowest, the reference operator setting unit 21 sets the operator 7 having the first priority as the "reference operator" (step S29). End the process.

In this way, a plurality of controls 7 are sequentially set as "reference controls" in order of priority, and the "current range" and "current parameter value" of the "reference controls" are sequentially updated. In step S10 of FIG. 7, since the operator 7 having the highest priority is first set as the “reference operator”, the “current range” and the “current parameter value” of all the operators 7 are set. Is updated. In step S17 of FIG. 8, since the operator 7 in which the operation is detected is first set as the “reference operator”, the operator 7 in which the operation is detected and the operator 7 having a lower priority than that of the operator 7 have an operation detected. The "Current Range" and "Current Parameter Value" are updated.

(6) Effect In the sound effect control device 100 according to the present embodiment, one of the controls 7 is set as the reference operator, and the priority is higher than the reference operator based on the parameter value of the reference operator. The operating range of the operator 7 (lower controller) with a lower value is determined. As a result, when the subordinate operator is operated, the parameter value corresponding to the subordinate operator changes only within an appropriate range depending on the parameter value corresponding to the reference operator. Therefore, the relationship between the parameter value corresponding to the reference operator and the parameter value corresponding to the lower-level operator is appropriately maintained. In this way, by appropriately maintaining the relationship between the parameter values of the plurality of controls 7, it is possible to prevent unintended changes in sound such as noise from occurring. Therefore, the user can appropriately control the acoustic effect by a simple operation without causing an audible discomfort without requiring special knowledge.

Further, the parameter value corresponding to the lower-level operator is determined based on the operation range of the lower-level operator and the state of the lower-level operator. As a result, the user can arbitrarily adjust the parameter value corresponding to the subordinate operator within an appropriate operation range depending on the parameter value corresponding to the reference operator by operating the subordinate operator.

Further, in the present embodiment, the sound effect information corresponding to the selected sound effect type is acquired, and it is determined whether or not a plurality of types of sound effect parameters are linked based on the sound effect information. In this case, for the sound effect type in which changes in the sound that the user does not intend are unlikely to occur, each sound effect parameter is adjusted independently without interlocking multiple types of sound effect parameters, and the sound effect is controlled with a high degree of freedom. can do. In this way, various sound effects can be appropriately controlled by switching the presence / absence of interlocking of sound effect parameters according to the sound effect type.

For example, both the operating range of parameter B and the operating range of parameter C may be determined based on the value of parameter A in FIG. Further, among the plurality of controls 7, only the sound effect parameters corresponding to some of the controls 7 may be interlocked, and the sound effect parameters corresponding to the other controls 7 may be arbitrarily adjustable. For example, the operation range of the parameter B depends on the value of the parameter A, but the operation range of the parameter C does not depend on any of the parameters A and B, and may be fixed to a certain range (for example, a reference range).

(C) In the above embodiment, the operation range of the sound effect parameter having the highest priority and the operation range of the sound effect parameter that is not the target of interlocking are set to the reference range represented by the sound effect information, but the user The upper limit value and the lower limit value of these operation ranges may be set.
