Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an effector or the like for applying a variety of effects to an input original sound signal to process and output a timbre, and more particularly to an effector equipped with a foot controller and a technique for editing an electronic musical instrument.

In an effector for a guitar or the like, both hands are blocked due to the nature of the rendition style. Therefore, a foot controller is used to perform patch switching and the like, but it is also possible to perform not only patch switching and other editing operations. desired.

[0003]

2. Description of the Related Art An effector is a device for processing various tone colors such as delay, reverb, chorus and flanger for an input original sound signal, and various effects can be selected by switching patches. . That is, in the effector, a patch (a kind of tone color unit) in which the mode of the effect to be applied is set by the user
It is decided by. A patch is a combination of an algorithm and a plurality of data such as parameters set by the user, which is preset in advance before playing. The algorithm is, for example, a program for adding an effect corresponding to each type of effect such as delay and reverb, and the parameter is an adjustment value with which the user operates the operator to set the tone color mode. For example, when delay is selected as an algorithm, delay time, feedback amount, etc. are parameters. A patch number (or patch name) is given to the patch, and the user can select the effect to be applied by the effector by designating the patch number and switching the patch.

Conventionally, in this type of effector, for example, in the case of a guitar effector or the like, both hands are blocked due to the rendition method, so that a foot controller is used to operate the effector by pedal operation. This foot controller is used for effect selection and parameter adjustment by patch switching. In this case, by pressing the foot switch (pedal switch, etc.) provided on the foot controller, the pressing operation is performed using the MIDI message channel message (program change message or control change message) from the foot controller. Corresponding to MID
A message defined by the I standard is sent to the effector main body, and the effector main body analyzes the message and performs the corresponding processing.

[0005]

The conventional foot controllers that can be operated are limited to those that change the performance sound during performance such as patch switching instructions and parameter value changes. So-called edit operations such as setting new contents (combination of algorithm and parameters, etc.) cannot be performed.

When performing this editing operation, the state of the effect is changed by switching the algorithm or changing the parameter value, and the performance is tested to see if the desired effect is obtained. It is necessary to repeat trial and error, such as switching between, changing parameter values, and playing again.

For this reason, for example, when editing the contents of a patch in a guitar effector, it is not possible to perform the editing operation while playing the phrase because both hands are blocked due to the playing method. It has to be interrupted and the editing operation must be performed on the effector body side, which makes the editing operation cumbersome.

The present invention has been made in view of the above problems, and an object thereof is to enable a so-called edit operation to be performed by a foot controller.

[0009]

FIG. 1 is a diagram illustrating the principle of the present invention. In order to solve the above problems, a foot controller connected to an effector or an electronic musical instrument body according to the present invention includes a mode switch 41 for selecting an edit operation mode and a plurality of foot switches 42.
And a transmitting means 43 for transmitting the operation information of the foot switch 42 when the edit operation mode is selected by the mode switch 41 to the main body as edit instruction information.

Further, according to the present invention, the main body device of the effector or electronic musical instrument to which the foot controller is connected,
Receiving means 44 for receiving information from the foot controller
And a judging means 45 for judging whether or not the received information is the edit instruction information, and an edit operating means 46 for performing an edit operation based on the edit instruction information when the judging means 45 receives and determines the edit instruction information.

The foot controller according to the present invention also has, as one mode, a mode in which the foot controller has a mode switch 41 for selecting an edit operation mode, and the mode switch 41 selects the edit operation mode. The operation information of the foot switch 42 at that time is transmitted to the main body of the effector or the electronic musical instrument as the edit instruction information, and when the main body receives the edit instruction information, the main body performs the edit operation based on the edit instruction information.

As another form of the edit operation method by the foot controller according to the present invention, the foot controller includes a mode switch for selecting an edit operation mode, and when the edit operation mode is selected by the mode switch, the edit operation mode is selected. After the operation mode selection notification information is sent to the main body of the effector or electronic musical instrument, and the main body receives the edit operation mode selection notification information, when the foot switch operation information is received from the foot controller, the editing operation corresponding to the operation information is performed. It's something that you do.

In the above edit operation method, the main body is
It is equipped with a correspondence table that associates the foot switch of the foot controller with the edit operator on the main body side, and the operation information of the foot switch received from the foot controller side is referred to this edit table to the edit operator. The corresponding edit operation can be performed in association with each other.

Further, in the above-mentioned edit operation method, at least the patch operation mode can be switched in addition to the edit operation mode, and the foot controller can operate the foot switch in the patch operation mode. Then, the patch switching information is transmitted to the main body, and the main body can switch the patch according to the received patch switching information.

Further, in the above-described editing operation method, the foot controller is provided with display means for displaying the state of the main body involved in editing, and in the edit operation mode, information indicating the state of the main body involved in editing is transmitted from the main body to the foot controller. The foot controller displays the state of the main body relating to editing on the display means based on the received information (for example, patch setting mode, main body setting mode, effect on / off state, currently selected). The parameter number / type and the set value are displayed).

The editing operators described above may include a parameter selection operator, a parameter value setting operator, and a setting storage instruction operator.

[0017]

In the present invention, when the foot controller is used for the edit operation, the mode switch 41 is used to select the edit operation mode.
Operate 2. When the edit operation mode is selected by the mode switch 41, the transmission means 43 transmits the operation information of the foot switch 42 as edit instruction information to the main body.

The main body receives the edit instruction information 44
When it is determined that the edit instruction information has been received by the determining means 45 and the content is received by the determining means 45, the edit operating means 46 performs the edit operation based on the edit instruction information. As a result, the editing operation that can be performed on the main body can also be performed by the foot controller.

In this case, if the foot switch of the foot controller and the edit operator on the main body side are associated with each other on the main body side in the correspondence table, not only the edit operation that can be performed on the main body can be performed by the foot controller but also the foot controller. Since the edit operation method in the controller corresponds to the edit operation method in the main body, even when performing the edit using the foot controller, there is no confusion about the operation method.

Further, if the display means is provided on the foot controller side, the setting state of the main body in the edit operation mode can be easily confirmed on the foot controller side, so that duplicate operations related to the edit operation can be prevented.

FIG. 2 is a diagram showing the overall configuration of the effector. As shown in the figure, it comprises a rack-type effector 1 as an effector main body and a foot controller 2 connected to this by a MIDI cable 3. The MIDI cable is a MIDI cable.
Two are used for in and MIDI out. A foot volume (volume pedal) 243 can be connected to the foot controller 2 as needed.

FIG. 3 is a diagram showing a block configuration of the internal circuit of the rack-type effector 1. In FIG. 3, 11 is a CPU (central processing unit) that controls the entire apparatus, 12 is a control program, a tone processing algorithm, a correspondence table of edit operators / foot switches (corresponding exclusive messages) described later, and the like. ROM (read only memory) for storing the data, 13 is a RAM (random access memory) for storing various work data, the setting state of the patch and the setting state of the effector body, and 14 is various operators , 15 is an LCD display unit, 16
Is an analog original sound signal converted to a digital original sound signal A
A / D converter, 17 is a DSP (digital signal processor) for performing a predetermined tone color processing on the digital original sound signal from the A / D converter 16, and 18 is a digital tone signal after the tone color processing is converted into an analog signal. A D / A converter, 19 is a bus connecting these circuits to each other.

The front panel of the rack-type effector 1 has L
A CD display unit 15 and various operators 14 are arranged. The operators 14 include encoders for various selections, various switch groups, various adjustment volumes, power switches, and the like.

Among these operators 14, the operators related to the edit operation (tone effect setting, other function setting) are a light switch, an EXIT switch, an effect switch, an edit switch, a utility switch, There are a parameter encoder and a value encoder, and other operators include a number encoder, an input volume, and an output volume. These functions are shown below.

Light switch: A switch for storing patch settings. ○ EXIT switch: A switch for canceling the operation and giving an instruction to exit from each mode. -Effect switch: A switch that specifies on / off of the effect. -Edit switch: A switch for entering a mode for making patch settings.

Utility switch: A switch for entering the parameter setting mode of the effector main body. The following are examples of parameters of the effector body. A parameter that determines the contrast of the LCD display unit 15.・ When the effect is turned off by the effect switch, you can decide whether to mute the tone-processed effect sound and output only the original sound, or to mute both the effect sound and the original sound. Parameters.・ When operating the effect switch, toggle the effect on / off each time the switch is operated (pressed), or turn on the effect only while operating (pressed) the switch. A parameter that determines whether or not.

Parameter encoder: An encoder for selecting a parameter by increasing or decreasing the parameter number. -Value encoder: An encoder for setting the value of a parameter by increasing or decreasing the set value of the parameter. -Number encoder: An encoder for selecting a patch by increasing or decreasing the patch number. * Input volume: Volume for adjusting the input level. * Output volume: Volume for adjusting the output level.

An example of a switch operating method for editing will be given below. (1) When editing a patch • Select the patch to be edited with the number encoder. • Press the edit switch to switch to patch setting mode. -Operate the parameter encoder to select the parameter to be set. • Operate the value encoder to set the parameter value. -Press the write switch to write the edited contents to memory. This automatically exits the patch setting mode.

(2) When editing the effector body • Press the utility switch to switch to the effector body setting mode. -Operate the parameter encoder to select the parameter to be set. • Operate the value encoder to set the parameter value. As a result, the automatically set parameter value is written in the memory. When editing the effector body, unlike editing a patch, the parameter value is set in the memory simply by setting the parameter value without operating the write switch.

In the above operation, by operating the EXIT switch, it is possible to exit from the patch setting mode and the effector main body setting mode. Further, by operating the effect switch to switch the effect on / off state, it is possible to confirm how the effect is applied.

With respect to these switches, push data in which 1 bit is allocated for each switch is prepared, and whether or not these switches are pressed is constantly monitored by a timer at predetermined time intervals. Therefore, when the switch is pressed, the corresponding bit in the push data is set to "1". As a result, the main program periodically checks the state of this push data and if there is a bit of "1", after returning it to "0", the mode of the switch corresponding to that bit or It is designed to shift to operation.

Further, the encoder outputs rectangular waves (having a cycle corresponding to the rotation speed) having different phases depending on the direction of rotation thereof. Counters for counting the amount of rotation of each encoder are provided for the respective right and left rotation directions, and thus there are a total of six counters. If the encoder outputs a rectangular wave indicating that the rectangular wave has been rotated to the right, the counter value corresponding to each cycle of the rectangular wave is incremented, and a rectangular wave indicating that the rectangular wave has been rotated to the left is generated. When output, the value of the counter corresponding to each cycle of the rectangular wave is incremented. The main program of the CPU 11 periodically performs the following processing.・ Read the value of each counter and increase / decrease the parameter number, parameter value, and patch number respectively according to the value.
Select parameters, set parameter values, and select patches.・ Clear each counter value.

As for the volume, A / D conversion is performed and the value is read. It should be noted that when the volume is changed, the display unit 15 displays the changed value for a certain period of time instead of the display content (for example, patch number) that has been displayed until then, so that the accurate value of the volume operation can be known. You can do it. It should be noted that after the elapse of the certain time, the display content is returned to the display content originally displayed.

As shown in FIG. 4, the foot controller 2
Are 13 foot switches (or pedal switches) 241 on the board and a mode switch 24 for mode selection.
2. A display LED (light emitting diode) 252 corresponding to each switch 241 and an indicator 251 are arranged, and a foot volume (volume pedal) 243 is provided if necessary.
Can be connected. This foot volume 243
Can output continuous set values. The numbers 1 to 13 are assigned to the foot switches 241 respectively, and the number 1 is assigned to the lower row.
~ 7 footswitches are arranged side by side, 6 footswitches numbered 8 to 13 are placed between the lower footswitch and the footswitch in the upper row, thereby using the foot controller as a keyboard In this case, the respective foot switches are arranged in a similar manner to the white and black keys of the keyboard so that the correspondence between the foot switches and the keys can be easily understood. LED 25 for display
Reference numeral 2 is for displaying that the corresponding foot switch is operated by turning on / off the light, and can be turned on / off from the outside by a predetermined exclusive message of MIDI information as described later. The display 251 displays the mode number selected by the mode switch 242.

FIG. 5 shows a block configuration of the internal circuit of the foot controller. As shown in the figure, 21 is a CPU that controls the entire foot controller, 22 is a ROM that stores a correspondence table of exclusive messages output in response to the foot switch and its operation, a control program, and 23 is a working memory. RA which is the area
M and 24 are a foot switch 241 and a mode switch 24
2 operators, 25 is a display LED 252 and a display unit 25
A display unit such as 1 and 26 are buses for connecting these circuits to each other.

The foot controller 2 is a mode switch 2
By pressing 42, the following three modes can be sequentially switched. The number of the selected mode is displayed on the display 251.

Mode # 1: Mainly patch (program)
This is a mode for making changes, which is a mode that is commonly used in conventional foot controllers. In this mode, a function is assigned to each foot switch 241 on the foot controller, and the instruction data of the function corresponding to the operated foot switch is MID.
It is transmitted to the rack effector 1 by a program change message of I information. Further, when the foot volume (volume pedal) 243 is connected, data indicating how much the foot volume 243 is stepped on is transmitted to the rack-type effector 1 by the main volume data of the MIDI information control change message. Sent.

Mode # 2: This mode is for performing operations relating to editing, and the foot controller 2 is used to remotely control the editing operation of the rack-type effector 1. In this mode, the footswitch operation information is transmitted to the rack-type effector 1 using a predetermined exclusive message in the MIDI information system message.

Mode # 3: This is a mode in which the foot controller is used as a pedal keyboard, and note-on / off information corresponding to each foot switch is a rack-type effector based on a MIDI information note-on message and note-off message. Sent to 1.

These modes # 1 to # 3 are sequentially switched by pressing the mode switch 242, but the function assigned to each foot switch 241 is different in each mode, and therefore the same foot switch operation is output. The MIDI information depending on each mode is different.

An example of the operation in mode # 1 will be described. Now, for example, if there are up to 100 patches, it is assumed that every 10 patches are regarded as one bank, and the bank has patch numbers 1 to 10.
In mode # 1, for example, the foot switches 241 of number 1 to number 10 are used as switches for designating the patch numbers corresponding to the patch numbers in the current bank, and one of the remaining foot switches is incremented in the bank. The function is assigned to each foot switch so that the other foot switch (for bank up) and the other one for decrementing the bank (for bank down) are used. Therefore, a desired bank is selected by using the bank up foot switch or the bank down foot switch, and the patch numbers in the bank are numbered 1 to 10.
Select with the foot switch of. This selection information is provided by the rack type effector 1 by the program change message.
The rack type effector 1 switches the patch to the designated patch number. When a patch number is selected with the switches of Nos. 1 to 10, the LED 252 corresponding to the operated switch is turned on, and the LED that has been turned on until then is turned off.

An example of the operation in mode # 3 will be described. In this mode # 3, an arbitrary pitch is assigned to each foot switch 241, and these foot switches 241 are used as a pedal keyboard for playing an external sound source or a pitch shift amount such as a pitch shifter built in an external effector. It is also used as a keyboard for controlling. When used as a pedal keyboard, the lower numbered foot switches 241 correspond to the white keys C, D ... B, and the upper numbered foot switches 241 correspond to C # and D #, respectively. No. 11 and 1 on each black key
2 and 13 foot switches are F #, G #, A # respectively
Corresponds to each black key. The number 10 foot switch 241 in the upper row does not correspond to any key. In mode # 3, the operation of the foot switches other than the number 10 foot switch in the upper row is valid, so the LEDs corresponding to the foot switches other than the number 10 foot switch in the upper row are effective.
Lights up to show the foot switch for which the operation is valid. When each foot switch 241 is pressed, the note-on message of the corresponding note number is output, and when the pressing is stopped, the note-off message of the corresponding note number is output.
Send to.

Next, the operation in the mode # 2 which is the edit operation according to the present invention will be described in detail with reference to FIGS. 6 and 7. Here, FIG. 6 shows the foot controller 2 when a switch is operated in the foot controller 2.
7 is a flowchart showing a processing routine of the rack type effector 1 when receiving MIDI information from the foot controller 2.

Each foot switch 241 of the foot controller 2 is associated with each operator for editing on the rack type effector 1 side, for example, as follows. "Rack-type effector 1" → "Foot controller 2" Light switch → Number 1 foot switch EXIT switch → Number 2 foot switch Effect switch → Number 3 foot switch Edit switch → Number 4 foot switch Utility switch → Number 5 foot switch Parameter encoder → Number 6 foot switch (for increment) Parameter encoder → Number 7 foot switch (for decrement) Value encoder → Number 8 foot switch (for increment) Value encoder → Number 9 foot switch (for decrement)

Note that the number encoder, input volume, and output volume are not controls for editing, but if there are a number of foot switches,
These number encoder, input volume, and output volume may also be used for operation in association with the foot switch.

This foot switch (exclusive
The correspondence table between the message) and the editing operator is provided on the rack-type effector 1 side. In addition, the foot controller 2 side is provided with a correspondence table of foot switches and their corresponding exclusive messages, and the operator name corresponding to each foot switch can be identified so that the correspondence with the edit operator can be known. Is displayed.

Now, when the switch is pushed on the side of the foot controller 2, the processing routine of the foot controller 2 of FIG. 6 is started. This processing routine is started when an interrupt occurs when any of the switches is turned on, and when the processing of the routine is completed, it returns to the routine that was being executed.

When the switch is pressed (step S1),
First, it is determined whether or not it is the mode switch 242 (step S2). When it is the mode switch 242, the mode setting corresponding to the operation is performed and the mode number is displayed on the display device 251, and when the previous mode is the mode # 1, that of each LED 252 is changed. Up to the RAM 23, and when the newly set mode is the mode # 1, the previously saved lighting states of the LEDs 252 are read from the RAM 23 and the LEDs 252 are turned on / off accordingly. And then
When the new mode is the mode # 3, the LED 252 corresponding to the foot switch other than the number 10 is turned on, and the LED corresponding to the number 10 foot switch is turned on.
The light 252 is turned off (step S3).

It is determined whether this mode setting is mode # 2 or not (step S4), and if it is mode # 2, a MIDI notification of mode # 2 setting indicating that mode # 2 has been selected is issued.
Information is transmitted to the rack-type effector 1 using a predetermined exclusive message corresponding to the mode # 2 setting notification (step S5).

The operated switch is the foot switch 24.
If it is 1, the current mode is determined (step S6). If it is mode # 1 or # 3, the operation information corresponding to the switch operation is MID as described above.
It is transmitted to the rack-type effector 1 side using a predetermined program change message, note-on message, and note-off message of the I information (step S7,
S9). In the foot switch processing of mode # 1, when the switches of the numbers 1 to 10 are operated,
The LED that has been lit until then is turned off, and the LED 252 corresponding to the operated switch is lit (step S
7). On the other hand, in the case of mode # 2, the operation information of the operated switch is transmitted to the rack type effector 1 side using a predetermined exclusive message corresponding to the operated switch of the MIDI information (step S8). ).

Upon receiving MIDI information from the foot controller 2 side, the rack-type effector 1 side activates the processing routine of the rack-type effector 1 shown in FIG. This processing routine is started upon interruption when MIDI information is received, and when the routine processing is completed, the routine that was being executed is returned to. When the MIDI information is received (step S11), it receives a predetermined exclusive information corresponding to the above-mentioned mode # 2 setting notification or operation information of the foot switch 241 defined between the foot controller 2 and the rack-type effector 1. It is determined whether the message is a message (step S12). If the message is other than the above exclusive message, processing according to the message content, for example, mode #
The patch switching process and the like in 1 are performed (step S1).
6).

On the other hand, if the message is the above-mentioned predetermined exclusive message, the message content is analyzed, and if the message content is the above-mentioned mode # 2 setting notification, the current status of the rack-type effector 1 side. If there is an LED display or the like corresponding to the operation status of each switch, the information is transmitted to the foot controller 2 using a predetermined exclusive message (step S14).

When the content of the message is the operation information of the foot switch 241, the edit operator corresponding to the operated foot switch is obtained from the above edit operator / foot switch correspondence table, and the edit is performed. The bit of push data corresponding to the operator is set to "1". If the operation information is a message corresponding to the encoder, the corresponding counter value is incremented (step S15).

Thus, as seen from the main program of the rack-type effector 1, the push data setting and the counter value setting for the encoder by the foot controller are the same as when the editing operator of the main body of the rack-type effector 1 is operated. Since the situation is the same, the main program shifts to the mode or operation according to the operation of the editing operator. At this time, when controlling the LED display or the like corresponding to each switch, the corresponding display control information is also notified to the foot controller 2 using an exclusive message at the same time.

When the current mode is the mode # 2, the foot controller 2 receives the LED display control information from the rack effector 1 side through an exclusive message, and the corresponding foot controller 2
The display LED 252 on the side is turned on / off. This LE
The following are examples of D display.・ Number 4 depending on whether it is in patch setting mode
The display LED 252 corresponding to the foot switch is turned on / off. -Display LED 25 corresponding to the foot switch of the nyver 5 depending on whether or not the setting mode of the effector body is set.
2 is turned on / off. -The display LED 252 corresponding to the number 3 foot switch is turned on / off according to the effect on / off state.

As a result, the mode or operating state of the rack-type effector 1 and the lighting state of the display LED 252 operated by the foot controller 2 coincide with each other.
By observing the display state of the display LED 252 of the foot controller 2, the user can easily know what kind of operation is currently being performed (effect on / off state, in which mode, etc.). It is possible to reduce operational mistakes such as performing the same operation twice.

As a method for making the operation of the rack type effector 1 that can be quickly operated using an encoder or a shuttle dial compatible with the switch operation of the foot controller, for example, the following method can be used.

(1) The foot controller 241 sends notification information to the rack-type effector 1 when the foot switch 241 is stepped on and when it is released.
Thereby, the period during which the foot switch is stepped on on the rack type effector 1 side can be detected, and while the foot controller is stepped on, the setting value of the operator corresponding to the foot switch on the rack type effector 1 side is set. Control is performed so that the value is sequentially incremented or decremented with the passage of time.

(2) Adjacent foot switches 241 on the foot controller 2 are associated with increment / decrement of one operator, and when one foot switch is depressed while the other foot switch is depressed, Allows the value to be changed with a certain range of change that is larger than when stepping alone.

As a method of making an operator (for example, a volume) whose value can be continuously changed on the rack type effector 1 side correspond to the switch operation of the foot controller 2, there are the following methods.

Two foot switches on the foot controller are assigned for increment / decrement, a foot volume 243 is connected to the foot controller, and the operation amount of the foot volume 243 is directly used as the operation amount of the rack type effector 1 side operator. Correspond. In this case, a rough operation can be performed with the foot volume 243, and a detailed operation can be performed with the two foot switches.

In carrying out the present invention, various modifications other than the above-described embodiments are possible. For example, in the above-described embodiment, in the mode # 2 for edit operation, the operation information of the foot switch is sent by a predetermined exclusive message of MIDI information, but the present invention is not limited to this. That is, if the foot controller 2 side notifies the rack type effector 1 of the setting / cancellation of the mode # 2, the mode setting state of the foot controller 2 can be grasped on the rack type effector 1 side. Is mode #
2 After setting, the operation information of the foot switch is transmitted by a normal program change message or control change message, and the rack type effector 1
With respect to the operation information such as the program change message or the control change message received while the foot controller 2 is set to the mode # 2, this is not treated as normal MIDI data, and the above-mentioned edit is performed. It may be handled as control information of a corresponding operator according to the operator / foot switch correspondence table.

In the above-described embodiment, the MIDI message is used to transmit and receive information between the rack-type effector 1 and the foot controller 2, but the present invention is not limited to this, and other than MIDI. It is also possible to connect both via a communication means.

Further, in the above-described embodiment, the number (type) of the parameter currently selected in the mode # 2 of the foot controller 2 and its set value are not displayed, but these are not displayed. It may be displayed. In this case, the rack-type effector 1 detects a new parameter selection operation or a parameter value setting device in the main program, on condition that any of the parameters is currently selected in the process of step S14. When this is done, it sends a predetermined exclusive message to the foot controller 2 for displaying these pieces of information regarding the selected or newly selected parameter,
The foot controller 2 makes a corresponding display according to the exclusive message.

In the above embodiment, the setting notification indicating that the mode # 2 has been switched is transmitted to the rack effector 1 only when the mode # 2 related to editing is switched on the foot controller 2 side. However, even if the mode is switched to another mode, mode # 2
Alternatively, a cancellation notice or a setting notice indicating that the mode has been switched to the corresponding mode may be transmitted to the rack effector 1. In addition, in the above-described embodiment, the rack-type effector 1 is used.
When it is detected that the edit control is operated, the LED display control information corresponding to each switch related to the edit operation of the foot controller 2 is displayed on the foot controller regardless of the mode on the foot controller 2 side. However, when the foot controller 2 side sends a mode # 2 cancellation notification or a setting notification to a mode other than mode # 2 to the rack effector 1 side, the foot controller 2 Since the rack type effector 1 side can also determine whether or not the side is in the mode # 2, the LED display control information described above may be transmitted to the foot controller 2 side only in the case of the mode # 2. The same applies to the above-described process of transmitting the display information regarding the currently selected parameter to the foot controller 2.

In the above embodiment, the mode switch 242 for mode selection of the foot controller 2 is not limited to the type operated by hand or the type operated by foot, but any of these may be used. If the foot-operated type is used, it is convenient because the mode can be switched by the foot during the performance. On the other hand, since the size of the switch operated by hand is smaller than that of the type operated by foot, if the area of the board on which the switch is installed cannot be made large, it is better to use the switch operated by hand. convenient. In this case, the mode cannot be changed with the foot during the performance, but since the mode can be changed only once before and after the edit operation, even if the mode is changed manually, it is not inconvenient in operation. .

Further, as the mode switch for selecting the mode, various methods other than the above-described embodiment can be realized. For example, like the foot volume 243, when a foot switch can be connected to the outside, the mode may be switched by this foot switch.
Alternatively, the mode switching may be performed by simultaneously operating a plurality of predetermined foot switches 241, continuously operating the predetermined foot switches 241 within a short time, or maintaining the operation state of the predetermined foot switches 241 for a predetermined time or longer. .

Further, in the above-mentioned embodiment, each foot switch 241 of the foot controller 2 is made to correspond to each operator related to the editing of the rack type effector 1, but if the number of foot switches 241 is sufficient, The surplus foot switches may be assigned to functions related to editing other than the operators existing in the rack effector 1. For example, it is possible to directly change the value of a specific parameter that is frequently changed without the parameter selection operation and the parameter value setting operation by the foot switches of Nos. 6 and 7.

Further, in the above-mentioned embodiment, the case where the present invention is applied to the effector has been described, but the present invention is not limited to this, and can be applied to an electronic musical instrument having a musical sound generating means. is there.

That is, generally in an electronic musical instrument, similarly to the effector described in the above-described embodiment, a plurality of patches for determining the pitch, tone color of musical tones to be generated, and characteristics of these acoustic characteristics with time change, as patches. A plurality of sets are preset as one set of parameters.
Here, a patch refers to a set of a plurality of parameters that determine the characteristics of an effect or a musical tone to be generated and is preset and stored, and an algorithm is also included in the parameter in a broad sense. The parameters in this case include, for example, pitch, cutoff frequency of a low-pass filter through which a musical sound passes, and so-called attack, decay, sustain, release, etc. that determine the generation mode of an envelope signal that controls the low-pass filter. . Also in the electronic musical instrument, similarly to the effector described in the above-described embodiment, it is possible to select an arbitrary one from a plurality of patches or change the set values of the parameters constituting the selected patch, that is, edit. Has become. Further, also in the electronic musical instrument, similarly to the effector described in the embodiment, the value of the parameter relating to the electronic musical instrument main body can be set. The parameters in this case include, for example, those for determining the contrast of the display and the function assigned to the performance operator such as the lever. Therefore, it is possible to connect a foot controller to the electronic musical instrument, perform an operation related to the edit operation using the foot controller in the same manner as in the above-described embodiment, and cause the electronic musical instrument to perform the corresponding edit operation processing.

[0071]

As described above, according to the present invention, the operation related to the edit of the effector or the electronic musical instrument can be performed by the remote control by the foot controller. Therefore, even when both hands are blocked due to restrictions on the playing method, such as an effector for a guitar, the editing operation can be performed during the performance.
