Description

  The present invention relates to a mixing console including a sub display that always displays an auxiliary menu for a parameter to be operated on a main display.

  Conventionally, mixing consoles used in concert halls, etc. that adjust the level and frequency characteristics of audio signals output from a large number of microphones and electric / electronic musical instruments placed on a stage, etc., and send them to a power amplifier are known. It has been. The user who operates the mixing console adjusts the volume and tone of each audio signal of musical instruments and singing to the state that seems to best represent the performance by operating various panel controls on the digital mixer. ing. The mixing console includes a bus for mixing an audio signal from an input channel and an output channel for outputting the mixed audio signal. Each input channel controls the frequency characteristics, mixing level, and the like of the input acoustic signal and outputs it to each mixing bus, and each mixing bus mixes the input acoustic signal and outputs it to the corresponding output channel. The output from the output channel is amplified and emitted from a speaker or the like.

  In a conventional mixing console, a parameter value used for signal processing can be edited in accordance with a user operation. For example, a mixing console is known in which a GUI (Graphical User Interface) screen for receiving parameter settings is displayed on a main display, and an editing operation is received using this screen. In this mixing console, a touch panel is provided on the main display so that the user can directly operate the GUI by touching the screen. In such a mixing console, by operating buttons and fields corresponding to specific parameters on the main screen to be displayed on the main display, a pop-up window displaying the details and list of the parameters is displayed. Detailed editing operations related to parameters can be performed in the window. This is because it is difficult to display a GUI for accepting detailed editing operations related to parameters on the main screen alone. When displayed, the display for accepting editing operations becomes finer, and visibility and This is because operability is lowered.

  However, if a pop-up window is displayed on the main display, the lower main screen becomes invisible during the display. In this case, if the main screen and the pop-up screen are simply displayed at different positions, after selecting the parameter to be edited on the main screen, the editing instruction is operated on the pop-up screen displayed at another location. Therefore, the operability deteriorates because the operation is performed at different places. Therefore, a mixing console that solves this problem has been proposed. In this mixing console, in addition to the display panel that displays the main screen, a touch panel that displays the detailed edit screen is provided, and by double-clicking the operator or block related to the parameter on the main screen, the clicked operator or The detailed edit screen corresponding to the block is displayed on the touch panel. A button for editing a plurality of parameters is displayed on the detailed edit screen displayed on the touch panel, and a plurality of parameters can be edited by operating the buttons.

  However, with the conventional mixing console, the detailed editing screen is displayed on the touch panel only when a special operation (double-click) is performed on the main screen for the purpose of editing multiple parameters on the touch panel. The detailed edit screen is not always displayed. The detailed editing screen only displays the parameter itself, and does not display an auxiliary operation function on the touch panel for copying or pasting the state of one selected parameter. However, there is a problem that an auxiliary operation function cannot be executed using the touch panel.

  Accordingly, the present invention provides a mixing console in which a menu for performing an auxiliary operation is always displayed on a sub display for a parameter that is an operation target on a display screen on a main display. It is an object.

In order to achieve the above object, a mixing console of the present invention has a touch panel function and is capable of displaying a plurality of parameters relating to a channel for a plurality of channels, and a first display means for the first display means. By detecting a touch operation, selecting a parameter corresponding to the touch operation from among a plurality of parameters displayed on the first display means, and detecting an operation of an operator that selects a channel, A first selection means for determining one parameter to be operated by selecting a channel corresponding to the operated operator among the plurality of channels; a touch panel function; When a parameter to be operated is determined by the selection means, an operation function related to the parameter A second display means always displays a submenu comprising a plurality of items, when a predetermined item is selected in the displayed submenu on the second display means, determined by the first selection means Second selection means for executing an operation corresponding to the selected item for the parameter to be operated, and the second display for a plurality of parameters displayed on the first display means. The most important feature is that it includes editing means that can be edited independently of the display state of the means.

  According to the present invention, since the submenu of the item of the operation function related to the parameter to be operated is always displayed on the second display unit, conventionally, it can be performed only on the main screen which is the first display unit. Auxiliary operation functions such as copying and pasting can be easily performed on the parameters displayed on the first display means without requiring troublesome operations such as pop-up display. In addition, parameters can be edited independently of the display state of the second display means.

FIG. 1 is a block diagram showing a configuration of a mixing console according to an embodiment of the present invention.
In the mixing console 1 shown in FIG. 1, a central processing unit (CPU) 10 executes a management program (OS: Operating System), and the overall operation of the mixing console 1 is controlled on the OS. The mixing console 1 includes a non-volatile ROM (Read Only Member) 11 in which operation software such as a mixing control program executed by the CPU 10 is stored, and a RAM (Random Access Memory) in which the work area of the CPU 10 and various data are stored. ) 12. The CPU 10 performs a mixing process by executing a mixing control program and applying a sound signal processing to a plurality of input sound signals by a DSP (Digital Signal Processor: Digital Signal Processor) 20. Note that by making the ROM 11 a rewritable ROM such as a flash memory, the operation software can be rewritten, and the version of the operation software can be easily upgraded. The DSP 20 adjusts and mixes the volume level and frequency characteristics of the input acoustic signal based on the set parameters under the control of the CPU 10, and controls the acoustic characteristics such as volume, pan, and effect based on the parameters. Digital signal processing is performed. The effector (EFX) 19 adds effects such as reverb, echo, chorus and the like to the mixed audio signal under the control of the CPU 10.

  The display IF 13 is a display interface that displays various screens related to mixing on the display unit 14. As shown in FIG. 2, the display unit 14 includes main displays 14a and 14b having a touch panel function, and a sub display 14c having a touch panel function. The detection IF 15 scans the operation elements 16 such as faders, knobs, and switches provided on the panel of the mixing console 1 to detect operations on the operation elements 16, and generates an acoustic signal based on the detected operation signals. Editing and operation of parameters used for processing can be performed. The communication IF 17 is a communication interface for communicating with an external device via the communication I / O 18, and is a network interface such as Ethernet (registered trademark). The CPU 10, ROM 11, RAM 12, display IF 13, detection IF 15, communication IF 17, EFX 19, DSP 20 exchange data and the like via the communication bus 21.

  The EFX 19 and the DSP 20 exchange data with the AD 22, DA 23, and DD 24 via the audio bus 25. The AD 22 is a plurality of analog input ports for inputting analog signals to the mixing console 1. The analog input signals input at the AD 22 are converted into digital signals and sent to the audio bus 25. The DA 23 is a plurality of analog output ports for outputting the mixed signal mixed from the mixing console 1 to the outside, and the digital output signal received via the audio bus 25 in the DA 23 is converted into an analog signal to be sent to the venue or stage. Output from the arranged speaker. The DD 24 is a plurality of digital input / output ports for inputting digital signals to the mixing console 1 and outputting the mixed digital signals to the outside. The digital input signals input at the DD 24 are sent to the audio bus 25. The digital output signal received via the audio bus 25 is output to a digital recorder or the like. The digital signal sent from the AD 22 and DD 24 to the audio bus 25 is received by the DSP 20 and subjected to the above-described digital signal processing. The DA 23 or DD 24 receives the mixed digital signal sent from the DSP 20 to the audio bus 25.

Next, FIG. 2 is a block diagram showing the mixing processing algorithm executed in the mixing console 1 as an equivalent hardware configuration.
In FIG. 2, a plurality of analog signals input to a plurality of analog input ports (AD 22) are converted into digital signals and input to an input patch 30. The plurality of digital signals input to the plurality of digital input ports (DD24) are input to the input patch 30 as they are. In the input patch 30, any one input port of a plurality of input ports that are signal input sources is set to each input channel (N is an integer greater than or equal to 1; for example, 96 channels) of the input channel unit 31. Input channels) 31-1, 31-2, 31-3,..., 31-N are selectively patched (connected). The audio signals In.1, In.2, In.3,..., In.N from the input ports patched by the input patch 30 are supplied to the input channels 31-1 to 31-N, respectively. .

  The input channel signals in the input channels 31-1 to 31-N in the input channel unit 31 are adjusted to M (M is an integer equal to or greater than 1) by adjusting the characteristics of the acoustic signal and controlling the delivery level by an equalizer or a compressor. : For example, it is sent to 24 mix buses (Mix Bus) 34. In this case, the N input channel signals output from the input channel unit 31 are selectively output to one or more of the M mixing buses 34. In the mixed bus 34, one or a plurality of input channel signals selectively input from arbitrary input channels among the N input channels are mixed in each of the M buses, and a total of M mixed outputs are output. Is done. The mixed outputs from each of the M mixed buses 34 are output channels (Output Channels) 32-1, 32-2, 32-3,. -M is output respectively. In each of the output channels 32-1 to 32-M, the characteristics of the acoustic signal such as the frequency balance are adjusted by an equalizer or a compressor, and the output channel signals Mix.1, Mix.2, Mix.3,. This M output channel signal Mix.1 to Mix.M is output to an output patch 33.

  In addition, one or a plurality of output channel signals among the M output channel signals Mix.1 to Mix.M from the output channel section 32 are selectively used as a matrix bus (P is an integer greater than or equal to 1; for example, 8). This is sent to the MTRX Bus 35. In the MTRX bus 35, in each of the P buses, one or a plurality of output channel signals selectively input from any of the M output channels are mixed, and a total of P mixed outputs MRX. 1, MRX.2, MRX.3,..., MRX.P are output to the output patch 33. As described above, the MTRX bus 35 further mixes (submixes) the signal mixed by the mixing bus 34 and outputs P-mixed submix signals MRX.1 to MRX.P. The submix signal can be used in the following cases. For example, if the performance hall is a concert hall and vocals are output to the first output channel, guitar is output to the second output channel, drums are output to the third output channel, etc., they are installed in the lobby or hallway of the hall. The acoustic signal emitted from the speaker is preferably an acoustic signal in which vocals, guitars, drums,... Are mixed. Therefore, by mixing the output channel signals Mix.1 to Mix.M of the vocal, guitar, drum,... Output from the output channel section 32 by the MTRX bus 35, the submix signal output from the MTRX bus 35 is obtained. MRX.1 to MRX.P can be emitted from speakers installed in the lobby or hallway.

  In the output patch 33, any one of the M output channel signals Mix.1 to Mix.M from the output channel section 32 and the P submix signals MRX.1 to MRX.P from the MTRX bus 35 is connected to a plurality of output ports (DA23). And DD24) can be selectively patched (connected), and the output channel signal patched by the output patch 33 is supplied to each output port. At the output port of the DA 23, the digital output channel signal is converted into an analog output signal, amplified by an amplifier, and emitted from a plurality of speakers arranged in the venue. Further, this analog output signal is supplied to an in-ear monitor worn by a musician or the like on the stage or reproduced by a stage monitor speaker placed in the vicinity thereof. A digital audio signal output from a digital output port section (DD24) having a plurality of digital output ports is supplied to a recorder, an externally connected DAT, etc., and can be digitally recorded.

Next, FIG. 3 shows the configuration of the display unit 14 and the configuration of the operation element 16 arranged on the panel in the mixing console 1 of the present invention.
The display unit 14 includes a main display composed of a main display (Left) 14a and a main display (Right) 14b which are touch panels, and a sub display 14c which is a touch panel. Below the main display (Left) 14a, for example, a physical panel (Left) 16a provided with a plurality of operators 16 constituting a channel strip for 8 channels is arranged, and below the main display (Right) 14b. For example, a physical panel (Right) 16b provided with a plurality of operators 16 constituting a channel strip for 8 channels is arranged. Furthermore, on the left side of the physical panel (Left) 16a, a physical panel (SELECTED CHANNEL SECTION) 16c provided with a plurality of operators 16 is arranged. In the main display, an intuitive operation with a touch panel is realized. In this case, on the main display, the area where the setting screen and the operation screen are displayed is clearly divided, and only necessary items are displayed when necessary, so that the touch panel can be operated while maintaining intuitive operation. I try to prevent misoperation.

  Specifically, the central area of the main display (Left) 14a is the OVERVIEW AREA L-1 on which the setting screen is displayed. In the OVERVIEW AREA L-1, eight channels on the physical panel (Left) 16a are displayed. The channel strip is configured so that the image manipulator displayed on the main display (Left) 14a and the plural manipulators 16 on the physical panel (Left) 16a are seamlessly connected in the vertical direction. Then, a screen of an example of a display mode shown in FIG. 4 described later can be displayed. The area above OVERVIEW AREA L-1 is NAVIGATION AREA L-2 on which the setting screen is displayed, and the block switching of the channel block assigned to the physical panel (Left) 16a can be performed. This channel block is a channel block consisting of a predetermined number, for example, 8 channels, and all the channel blocks are always displayed on the NAVIGATION AREA L-2, and the desired channel block is displayed by touching the desired channel block. L-1 and physical panel (Left) 16a can be assigned. Each displayed channel block always displays the input / output meter and fader position, allowing you to see an overview of the entire channel.

  In addition, the area on the left side of OVERVIEW AREA L-1 and NAVIGATION AREA L-2 is Selected Channel Area L-3 where the operation screen is displayed, and Selected Channel Area L-3 contains the currently selected channel. On the other hand, an image manipulator that makes it possible to always operate important parameters is displayed. The Selected Channel Area L-3 is linked to the physical panel (SELECTED CHANNEL SECTION) 16c, and the channel assigned to the Selected Channel Area L-3 by the operator 16 provided on the physical panel 16c is real-time. You can operate all items that need to be operated. SELECTED CHANNEL AREA L-3 displays channel parameters that cannot be expressed on the physical panel (SELECTED CHANNEL SECTION) 16c. These can be broadly classified into “parameters that make up the sound itself”, “routing parameters”, and “other parameters”. In SELECTED CHANNEL AREA L-3, operation and display functions for the parameters of the assigned channel are always provided regardless of the state of other areas.

  Next, the central area of the main display (Right) 14b is the OVERVIEW AREA R-1 where the setting screen is displayed, and this area is the same as the OVERVIEW AREA L-1 described above. Description is omitted. The upper area of OVERVIEW AREA R-1 is NAVIGATION AREA R-2 where the setting screen is displayed, and is the same as NAVIGATION AREA L-2 described above. Furthermore, the area on the right side of OVERVIEW AREA R-1 and NAVIGATION AREA R-2 is ADMINISTRATION AREA R-3 where the operation screen is displayed. The ADMINISTRATION AREA R-3 controls the overall mode of the mixing console 1 as an overall control area and does not depend on the state of other areas. Functions that cannot be expressed only by channel parameters, such as configuration in the mixing console 1, are called from this area.

Here, an example of the display mode of the screen displayed on the main display of the mixing console 1 according to the present invention is shown in FIG. In FIG. 4, an example of the display mode of the OVERVIEW AREA L-1 on the main display (Left) 14a and the configuration of the physical panel (Left) 16a are shown, but the OVERVIEW AREA R-1 on the main display (Right) 14b is shown. Are displayed in the same display manner, and the configuration of the physical panel (Right) 16b is the same.
On the OVERVIEW AREA L-1 in the main display (Left) 14a shown in FIG. 4, an image manipulator 41 for each parameter for eight channels constituting the channel block assigned to the area is displayed. The image operation elements 41 of each channel are arranged in 16 long and narrow lines in the vertical direction, and important parameters for the channel and parameters to be operated in real time are assigned to each image operation element 41. Then, the image operation elements 41 arranged in the elongated direction in each channel displayed on the OVERVIEW AREA L-1 and the operation elements 16 arranged in the elongated direction in the physical panel (Left) 16a seem to be seamlessly connected in the vertical direction. A channel strip 42 for one channel is formed, and in the case shown in FIG. 4, channel strips 42 for eight channels are formed. In OVERVIEW AREA L-1, a parameter assigned to the touched image operator 41 is selected by touching one of the displayed image operators 41. For example, when the image operator 41 of the parameter “VoFB” is touched in any channel, the parameter “VoFB” is selected, and a rectangular frame 40 surrounding the image operator 41 of the selected parameter is displayed. By touching one image operator 41, the same parameter is selected for each channel displayed in the OVERVIEW AREA L-1, and the image of the parameter “VoFB” is shown for each channel as shown in the figure. A rectangular frame 40 surrounding the operation element 41 is displayed in an overlapping manner in each channel.

  When one of the parameters is selected as described above, the value of the selected parameter can be changed in the operator 43 by operating the operator 43 in the upper stage of the physical panel (Left) 16a. What is changed by the operator 43 is the selected parameter of the channel assigned to the channel strip 42 to which the operator 43 belongs. The parameter can be edited by the operator 43 regardless of the display state of the sub display 14c described later. When the SEL key 44 provided on the physical panel (Left) 16a is operated, the channel strip 42 to which the operated SEL key 44 belongs is assigned to the selected channel area L-3 and the physical panel (SELECTED CHANNEL SECTION) 16c. Channel is assigned. Then, by operating the operator 16 provided on the physical panel (SELECTED CHANNEL SECTION) 16c, the parameters of the assigned channel can be edited. Further, when the channel fader 45 provided on the physical panel (Left) 16a is operated, the level of the channel assigned to the channel strip 42 to which the operated channel fader 45 belongs can be edited.

  In the example shown in FIG. 4, the SEL key 44 of the third channel 3 from the left side on the physical panel (Left) 16a is selected and lit. As a result, the parameter “VoFB” in the channel 3 in the selected parameter “VoFB” is focused, and the focused parameter “VoFB” is set as the operation target parameter, and includes an operation item for the operation target parameter. The sub menu (CONTEXT MENU) and the input image (CONTEXT PAD) are always displayed on the sub display 14c. The display mode includes the CONTEXT MENU mode and the CONTEXT PAD mode. In the CONTEXT MENU mode, a CONTEXT MENU consisting of items of auxiliary operation functions for copying and pasting the focused parameter is displayed. In this case, the items in the CONTEXT MENU are displayed according to the type of the focused parameter. In the CONTEXT PAD mode, a software keyboard for inputting numerical values for the focused parameter and a surround pan display screen when the pan parameter is focused are displayed as the CONTEXT PAD. Note that the parameter specified by focusing is one parameter, and the sub-display 14c displays a CONTEXT MENU and a CONTEXT PAD that allow an operation on the focused parameter. The display mode of the screen displayed on the sub display 14c will be described later.

  In addition, OVERVIEW AREA L-1 and OVERVIEW AREA R-1 can display the detailed editing screen of the selected channel, and you can make detailed settings for the channel selected in this detailed editing screen. it can. FIG. 5 shows a display mode in which the detailed edit screen is displayed in OVERVIEW AREA L-1. In the display screen shown in FIG. 5, the SEL key 44 of channel 3 is operated to light up, and the detailed edit screen of the selected channel 3 is displayed in OVERVIEW AREA L-1. As shown in the figure, channel 3 is an input channel, and the detailed editing screen shows the head amplifier (HA) level, the attenuator (ATT) attenuation level, the equalizer (EQ) frequency characteristic curve, and the compressor (Comp). An image operation element 41 for adjusting a curve, a send level to the mixing bus 34, and a master level is displayed. Then, the image operation element 41 of the head amplifier (HA) is touched, and a rectangular frame 40 surrounding the image operation element 41 is displayed. In this case, the head amplifier (HA) level parameter is focused, and the CONTEXT MENU and CONTEXT PAD capable of performing operations on the focused parameter are always displayed on the sub display 14c. In the OVERVIEW AREA L-1 display screen shown in FIG. 4, by operating the SEL key 44 of any channel, the OVERVIEW AREA L-1 display screen changes to the detailed editing screen shown in FIG. 5 for any channel. It will be switched. In this case, a detailed editing screen may be popped up and displayed on the OVERVIEW AREA L-1.

An example of the display mode displayed on the sub-display 14c is shown in FIG. The sub display 14c is a display unit for auxiliary operation of the main displays 14a and 14b, and improves the operability for the user. In addition, the sub display 14c realizes an intuitive operation using a touch panel.
As shown in FIG. 6, the display area of the sub-display 14c is divided into three areas: a long and narrow channel strip function area S-1, an upper utility area S-2, and a user-defined key area S-3. Yes. Of the channel strip controls to which the focused parameter belongs, ASSIGNABLE FUNCTION ENCODER, Fn KEY, CUE KEY, and CHANNEL METER are assigned to the channel strip function area S-1, and the channel strip function area S-1 corresponds to the focused parameter. The function is displayed. In the case shown in FIG. 6, a state in which Input Gain is assigned to ASSIGNABLE FUNCTION ENCODER is displayed, and Fn KEY (Function KEY) is not displayed, but CUE KEY and CHANNEL METER are displayed. In the utility area S-2, CONTEXT MENU and CONTEXT PAD are displayed for the parameters focused on the main displays 14a and 14b, and the CONTEXT PAD has an interface for directly inputting values. . In the case shown in FIG. 6, the CONTEXT MENU is displayed in the utility area S-2.

  In the utility area S-2, when the user touches either the “CONTEXT MENU tab” or the “CONTEXT PAD tab” provided at the top of the area, the CONTEXT MENU or CONTEXT PAD corresponding to the touched tab is displayed. Is displayed. In this case, it may be determined in advance according to the type of parameter to be focused, which of the CONTEXT MENU and the CONTEXT PAD is to be preferentially displayed. In the case shown in FIG. 6, the CONTEXT MENU mode is set and the CONTEXT MENU is displayed. Furthermore, a maximum of 24 user-defined keys (USER DEFINED KEYs) are arranged on the screen in the user-defined key area S-3. Since four switching keys for switching between banks A, B, C, and D are arranged above the user-defined keys, a maximum of 24 × 4 user definitions can be set for each key. An “Edit” key is arranged next to the switching key. In the illustrated example, the bank A key is lit and bank A is selected. Also, four physical operators 50 are arranged under the sub-display 14c, and a user-defined function can be assigned to each of the physical operators 50. In the user-defined key area S-3, an arbitrary function defined by the user is assigned to an image operator or a hardware operator on the GUI, and a function corresponding to the selected user-defined key can be used. By touching the “Edit” key, a screen for setting user-defined keys is opened, and each user-defined key can be set.

In the CONTEXT MENU displayed in the utility area S-2 in FIG. 6, the following item buttons can be displayed, and each item will be described below.
“COPY”: Saves the operation target parameter to the copy buffer.
“CHANNEL COPY”: Saves the parameters of the entire channel strip including the parameter to be operated to the copy buffer.
“PASTE”: Reflects (pastes) a parameter from a copy buffer to a parameter to be operated (or a channel including the parameter). Since parameters have types such as level and frequency, pasting is possible only when the type of the parameter to be operated is equivalent to the type of the copied parameter, and pasting is not possible when the type is different. The
“COPY TO [ALL xxx ↑ ↓]” (xxx: MIX / MATRIX): All parameters of Send Level / On / Pan / Follow Fader to be operated are sent to the mixed bus 34 or MTRX bus 35 in the same channel. Reflect to send. No copy buffer is used. The portion “xxx” is “MIX” when the operation target is the mixing bus 34, and is “MATRIX” when the operation target is the MTRX 35. Each bus of the mixer is generally arranged in the column direction like the MTRX bus 35 shown in FIG. 2, and the “↑ ↓” is indicated in the item because the copying direction is the vertical direction.

“COPY TO [ALL xxx] (xxx: CH / MIX / MATRIX / ST / DCA, etc.)”: Reflects the target parameter directly on all channels. No copy buffer is used. The “xxx” portion varies depending on the operation target. When the operation target is a send parameter, “COPY TO [ALL xxx ← →]” and “← →” are added. This is because each bus of the mixer is generally arranged in the column direction like the MTRX bus 35 shown in FIG. 2, and the channel direction to be copied is in the horizontal direction, so that “← →” is indicated in the item. .
“COPY TO [ALL xxx x ALL xxx]”: Reflects the send level / on / pan / follow fader parameters of the operation target to all sends of all channels. No copy buffer is used. The “xxx” portion varies depending on the operation target. For example, “COPY TO [ALL CH × ALL MIX]”.

“UNDO”: Returns the state to the starting point of the last UNDO. The start point is created when the UNDO target CONTEXT MENU is executed, either immediately before it, or immediately after the popup is opened (except for some popups). Up to 10 starting points are stored, and information on the oldest starting point is sequentially deleted each time the starting point is stored. The parameters held at the starting point are all the parameters to be executed when the CONTEXT MENU for UNDO is executed, and all the parameters handled by the popup when the popup is opened. In the case of UNDO, UNDO is performed by forcibly recalling the parameter group stored as the starting point (however, recall safe cannot be performed). In addition, the parameters to be subjected to UNDO execution are stored as the redo starting point immediately before UNDO execution.
“REDO”: Returns the state to the starting point of the latest Redo. A starting point is created immediately before undo execution, and the state of all parameters subject to undo execution is retained. Although the number of starting points is not limited, since the starting point is created by performing UNDO, it actually depends on the number of possible undos. Note that redo is enabled when UNDO is performed, but if any parameter is changed in the enabled state, all redo starting points are deleted and the redo is disabled.

“SET DEFAULT”: Returns the focused operation target parameter to the default value.
“SET NOMINAL”: The focused operation target parameter is set to a nominal value (0 dB).
“SET DEFAULT (CHANNEL)”: Resets the parameters of the entire channel strip including the operation target to the default values.
“GLOBAL PASTE”: The GLOBAL PASTE screen is opened, and only the focused operation target parameter is pasted (overwritten) on the existing Snapshot. You can select multiple destination snapshots. Snapshot refers to a setting state of sound created when the DSP 20 performs signal processing using a signal processing parameter set.
“GLOBAL PASTE (CHANNEL)”: The GLOBAL PASTE screen is opened, and only the channel strip that contains the operation target is pasted (overwritten) on the existing Snapshot. You can select multiple destination snapshots.
“LR-MONO TYPE”: Displays the LR-MONO TYPE SELECT screen, allowing you to select stereo or monaural TYPE. This can be selected only when the focused operation target is an input channel of STEREO TYPE.
“IDENTIFY”: By blinking the display 14 of the actual machine corresponding to the focused device, the focused device can be specified when there are a plurality of devices. When it is selected again, it stops blinking.
“HELP”: Displays the help screen and jumps to help for the selected element.

Since the CONTEXT MENU items displayed in the utility area S-2 include items corresponding to the parameters, the contents of the CONTEXT MENU change for each focused parameter. However, the menu contents of the predetermined parameters are common. In this case, the utility area S-2 has a large number of items corresponding to the focused parameter, and may not be able to display all of the items in the utility area S-2 having a limited area size. FIG. 7 and FIG. 8 show other display modes in the utility area S-2 displaying the CONTEXT MENU in such a case.
In the display modes shown in FIGS. 7 and 8, a display switching button 51 is provided, and the display switching button 51 is operated to switch from the display mode of FIG. 7 or 8 to the display mode of FIG. 8 or FIG. be able to.
