Description

  The present invention relates to a mixing apparatus and a program for performing signal control on a plurality of input musical tone signals and generating one to a plurality of output signals by appropriately mixing them. In particular, the present invention relates to a mixing apparatus and a program that can perform settings related to signal control of a plurality of input musical sound signals in a state where the contents can be intuitively grasped and by a simple operation.

Conventionally, for example, in concert venues, clubs or studios, signal control is performed for each of a plurality of musical sound signals input from input devices (senders) that generate musical sounds such as a large number of microphones and a plurality of electric / electronic musical instruments (For example, volume level control) and then appropriately mixing (so-called mixing) to generate one or a plurality of output signals, and the generated output signals (mixing signals) are monitor speakers. There are known mixing apparatuses that output to one or a plurality of output devices (output destinations). In such a mixing apparatus, a large number of setting operators for performing various settings related to signal control of each of a plurality of input musical tone signals (hereinafter simply referred to as input signals) are arranged on a mixing console (operation console). Thus, the operator can adjust the output signal that is finally output by appropriately operating these setting operators to control the input signal. In addition, a display device such as a liquid crystal display is provided in the mixing device, and a pseudo operation device imitating an actual setting operation device is displayed on the display device, and an operator can operate this. The input signal can be controlled in the same manner as when the actual setting operator is actually operated. A number of such devices are known, but an example is the device described in Patent Document 1 shown below. In this specification, the term “musical sound” is not limited to musical sound, but is used in the sense that it may include voice or other arbitrary sounds.

  However, the mixing device that controls the input signal in accordance with the operation of the pseudo operation element as described above only displays on the display the simulation operation element that imitates the actual setting operation element that is actually disposed. Therefore, regarding the operation mode, the target input signals that can be set, and grasping of the correspondence relationship with the setting contents (control values, etc.), there is no difference between the simulated operator and the actual setting operator. For this reason, the operator cannot naturally use the simulated operator unless the operator knows in advance the association relationship as in the case of the actual setting operator. In other words, the conventional device only displays a simulated operator imitating an actual setting operator, and which output signal or which input signal is affected by operating each simulated operator (reflection) The information on the signal control such as how much operation can be applied to the input signal and how to change it can not be obtained intuitively from the screen display. There is a problem that it is very troublesome for the operator to grasp the information related to the control in advance for each simulated operator. Even if the simulated operation element can be used in the same way as the actual setting operation element, the operation mode is the same as the actual setting operation element, which is boring.

  The present invention has been made in view of the above points, and the operator can easily set the volume level for the signal control of the input signal on the display unit in a state where the contents can be intuitively grasped for each output signal. It is an object of the present invention to provide a mixing apparatus and a program that can be operated.

  The mixing apparatus according to the present invention performs signal control on each of a plurality of tone signals input from a plurality of input devices, and mixes them based on a predetermined input / output path of tone signals. A mixing device that outputs to each of a plurality of output devices, the display unit, a plurality of input device displays corresponding to the input device, and one or more output device displays corresponding to the output device on the display unit. Control means for displaying a signal line representing a correspondence relationship between a transmission source and an output destination of a musical sound signal to be mixed from the input device display to the output device display based on the mixing input / output path of the musical sound signal; And setting means for setting the volume level of each of the plurality of musical sound signals, and the control means is configured to input the input musical sound signal. And displaying said signal lines in different display modes on the volume level for each depending on the volume level or sound level after the signal control based on the set signal.

  According to the present invention, the input device display corresponding to a plurality of input devices that are the transmission source of the music signal to be mixed, and the output device display corresponding to one or more output devices that are the output destination of the music signal after mixing. The tone signal is displayed together with a signal line indicating a correspondence relationship between the transmission source and the output destination of the tone signal to be mixed based on the mixing input / output path. That is, signal control is performed on each of a plurality of musical tone signals input from a plurality of input devices, and the signals are mixed based on a predetermined musical sound signal mixing input / output path to each of one to a plurality of output devices. About the mixing apparatus to output, it displays in the state which looked down at the display means. The signal line is displayed in a different display mode for each volume level according to the volume level of the input musical sound signal or the volume level after signal control based on the setting. As a result, the operator can intuitively grasp the correspondence between input signals reflected on each output device (that is, the correspondence between the transmission source and the output destination) and the volume level.

  As a preferred embodiment of the present invention, the detection means for detecting that the display surface of the display means is touch-operated, and the touch operation detected by the detection means for any of the signal lines displayed on the display means Determination means for determining whether or not the operation is an operation, and the setting means is configured to detect the operation of any of the signal lines displayed on the display means. A setting is made to adjust the volume level of the musical tone signal corresponding to the signal line of the musical tone signal. Further, the determination means determines that a touch operation of a movement that widens or narrows the display width of the signal line is an operation for one of the signal lines displayed on the display means, and the setting means The control means performs a setting to increase the volume level in the case of a touch operation with a movement to widen the display width, while decreasing the volume level in the case of a touch operation with a movement to narrow the display width of the signal line. The display width of the signal line is appropriately changed and displayed according to the volume level set by the setting means. In this way, the volume level of the corresponding input signal can be controlled in accordance with an operation of expanding or narrowing the display width of the displayed signal path with a finger, and the display width of the signal line is changed accordingly. Therefore, the operator can easily set the settings related to the volume level of the input signal on the display unit for each output signal that reflects the input signal, and perform simple operations on the screen. Can be fun to do.

According to the present invention, all output devices and input devices capable of signal control are displayed on the screen in a bird's-eye view, and the signal path of the input signal input to the desired output device is displayed in different display modes depending on the volume level. Since the display is made, the operator can intuitively grasp the correspondence relationship with the input signal and the volume level for each output signal reflecting the input signal. .
In addition, the operator can make a setting related to the volume level of the input signal on the display unit happily with a simple operation on the screen in a state where the setting contents can be intuitively grasped for each output signal reflecting the input signal. Will be able to.

  Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

  FIG. 1 is a hardware configuration block diagram showing an embodiment of the overall configuration of a mixing apparatus according to the present invention. The mixing apparatus shown in the present embodiment is, for example, a mixer for audio signal control, and a hardware configuration example of the mixer is configured using a computer, in which the CPU 1 is input from a plurality of input devices 7A. An output signal (mixing signal) generated by appropriately combining input signals (audio signals) is generated, and the entire mixer is controlled so that the generated output signal is output from any one of the one to a plurality of output devices 8A. . However, in this embodiment, the entire mixer is controlled by a single CPU 1 so as to mix a plurality of input signals, and actual mixing processing and signal control processing for input signals and output signals are separately provided for signal control. A description will be given by taking as an example what is executed by a prepared dedicated digital signal processor (DSP) DP. Here, the case where the minimum necessary resources are used is shown.

  Although details will be described later, in this embodiment, the microcomputer including the CPU 1, the ROM 2, and the RAM 3 executes software including a predetermined control program, thereby allowing the operator to touch the screen on the multi-point touch display 6C. Accordingly, as an example of changing various settings related to signal control of the input signal, the digital signal processing circuit DP is instructed to change the volume level (so-called SEND level) for inputting the input signal and outputting it to a predetermined output signal. The display mode of the corresponding signal line displayed on the multipoint touch display 6C is changed. Of course, such control is not limited to the form of computer software, but can also be implemented in the form of a microprogram processed by a DSP (not shown) separate from the digital signal processing circuit DP for signal control that executes signal mixing and the like. In addition, the present invention is not limited to this type of program, and may be implemented in the form of a dedicated hardware device including a discrete circuit, an integrated circuit, a large-scale integrated circuit, or the like.

  For the CPU 1, via a communication bus (eg, data and address bus) 1D, ROM 2, RAM 3, detection circuits 4, 6A, display circuits 5, 6B, digital signal processing circuit (DSP) DP, storage device 9, A MIDI interface 10 and a communication interface 11 are connected to each other. Further, the CPU 1 is connected to a timer 1A for measuring the interrupt time and various times in the timer interrupt process (interrupt process). For example, the timer 1A generates a clock pulse, and gives the generated clock pulse to the CPU 1 as a processing timing command or to the CPU 1 as an interrupt command. The CPU 1 executes various processes according to these instructions.

  The ROM 2 stores various programs executed by the CPU 1 and various data. The RAM 3 is used as a working memory that temporarily stores various data generated when the CPU 1 executes a predetermined program, or as a memory that stores a currently executed program and related data. A predetermined address area of the RAM 3 is assigned to each function and used as a register, flag, table, memory, or the like.

  The operation element 4A includes a plurality of input / output channels corresponding to a plurality of input / output channels for performing various settings such as control values for signal control of each input or output signal related to mixing processing executed by the digital signal processing circuit DP. A large number of setting operators are arranged on a mixing console that also serves as a main body panel. As conventionally known, as the operation element 4A, for example, an effective / invalid setting operation element for selecting / designating a channel to be operated, a rotary encoder for adjusting a control value for pan control, and setting a control value in more detail A selector switch for switching, a cue (CUE) switch for audition, a volume level (SEND level) for inputting an input signal and outputting it to a predetermined output signal, and a mixed signal are output as a main output signal There are various types such as a button type, a rotary type, a slide type, or a jog shuttle, such as a fader for adjusting a volume level for setting a control value related to the volume such as a volume level. The detection circuit 4 detects the operation state of the operation element 4A, and sends an instruction to change a control value (volume level, etc.) according to the operation state via the data and address bus 1D to the CPU 1, the display 5A, and the multipoint touch type. The data is output to the display 6C and the digital signal processing circuit DP.

  The display circuit 5 displays various information such as a control value of the CPU 1 and a control value currently set in accordance with the operation of the operation element 4A on a display 5A composed of, for example, a liquid crystal display panel (LCD) or a CRT. . The display 5A is a general display widely used in a conventionally known mixer, and is disposed on a mixing console together with the operation element 4A.

  On the other hand, the display circuit 6B controls the display of the multipoint touch display 6C provided separately from the display 5A. Of course, the display circuit 5 can display various information such as control values currently set according to the operation of the operation element 4A as characters, but it does not display such control values as characters themselves, but a graphic image. (As will be described later, for example, a device display corresponding to each device and a linear signal line for the volume level of the input signal can be displayed.) Further, the multipoint touch display 6C is not only provided with a display function for displaying characters, graphic images, etc., but can be displayed corresponding to the touched screen position by an operator touching the screen. It also has a so-called touch panel function for performing various settings according to the display (the displayed graphic image functions as a soft switch). The detection circuit 6A specifies the screen position touched by the operator. A detailed description of a screen display example on the multipoint touch display 6C and a method for setting the volume level of the input signal using the multipoint touch display 6C will be described later (see FIG. 2 described later). Note that the operation element 4A, the detection circuit 4, the display 5A, and the display circuit 5 may be omitted, and all display and operation detection may be performed by the multipoint touch display 6C.

  The digital signal processing circuit DP is a signal control circuit that performs mixing processing and signal control for input signals and output signals independently of the CPU 1, and is connected to the outside of the mixer via the input signal interface 7. A musical tone signal is acquired from each of the plurality of input devices 7A. The input signal interface 7 is an interface device prepared for a plurality of input channels in order to obtain a musical sound signal (for example, an audio signal) from each of the plurality of input devices 7A. The instruction to change various settings related to the signal control of the input signal executed by the digital signal processing circuit DP is performed according to the operation of the operation element 4A, and a multipoint touch display 6C described later. It is performed in accordance with a predetermined touch operation by the operator above. The digital signal processing circuit DP performs mixing processing after performing signal control of each of the plurality of input signals acquired from the input device 7A based on a control value such as a volume level set according to the operation. The output signal (mixing signal) that has been subjected to the mixing process generated by the digital signal processing circuit DP is output to one or more output devices 8A connected to the outside of the mixer via the output signal interface 8. The output signal interface 8 is an interface device prepared for a plurality of output channels in order to supply an output signal to each of one to a plurality of output devices 8A. The input / output path of the musical sound signal that specifies the combination of input signals to be input as mixing targets and the output device to which the mixed signals are to be output is arbitrarily determined by the operator in advance. It is decided to.

  The storage device 9 stores various data and various control programs executed by the CPU 1. When the control program is not stored in the ROM 2 described above, the control program is stored in the storage device 9 (for example, a hard disk) and read into the RAM 3 to store the control program in the ROM 2. It is possible to cause the CPU 1 to have the same function. In this way, control programs can be easily added and upgraded. The storage device 9 is not limited to a hard disk (HD), but may be a flexible disk (FD), a compact disk (CD-ROM / CD-RAM), a magneto-optical disk (MO), or a DVD (Digital Versatile Disk). Any storage device may be used as long as it uses a storage medium in the form. Alternatively, a semiconductor memory such as a flash memory may be used.

  The MIDI interface (I / F) 10 inputs MIDI data from another externally connected MIDI device 10A (for example, a sequencer or an external keyboard) to the device, or receives MIDI data from the device as another MIDI device 10A. This is an interface to output to. The other MIDI device 10A may be any device that generates MIDI data.

  The communication interface (I / F) 11 is connected to a wired or wireless communication network X such as a LAN, the Internet, or a telephone line, and is connected to the server device 11A via the communication network X, and the server device 11A. This is an interface for taking control programs or various data from the electronic musical instrument side. Further, when the control program and various data are not stored in the ROM 2 or the storage device 9 (for example, hard disk), it is used for downloading the control program and various data from the server device 11A. Such a communication interface 11 may be both wired and wireless and may include both.

  Note that the above-described mixing device is not limited to one in which the operation element 4A, the display 5A, the multipoint touch display 6C, the storage device 9 and the like are built in one device body, but each is configured separately, and has a MIDI interface, Needless to say, the present invention can be similarly applied to devices configured to connect devices using communication means such as various networks.

  Next, a screen display example of the multi-point touch display 6C described above and a user operation mode on the screen for performing settings related to signal control of an input signal using the screen display will be described with reference to FIG. . FIG. 2 is a conceptual diagram showing an example of a screen display on the multipoint touch display 6C. In order to make the explanation easier to understand, a display example in the case of using a plurality of microphones 7A as an input device (transmission source) and a plurality of monitor speakers 8A as an output device (output destination) is shown. The manner of operation will be described by taking as an example the case of setting the volume level of the input signal from each microphone 7A sent to each monitor speaker 8A (so-called SEND level setting).

  The multi-point touch display 6C is configured separately from the mixer main body Z including the display 5A. The detection circuit 6A and the display circuit 6B (see FIG. 1) included in the mixer main body Z are connected using a cable or the like. It is connected. The multipoint touch display 6C connected to the mixer main body Z includes a signal transmission source input device 7A connected to the mixer main body Z via an input signal interface 7 including an input cable and the like. Corresponding to the output device 8A of the output destination of the signal connected via the output signal interface 8 including the output cable and the like, a graphic image (icon or the like) corresponding to these devices is displayed on the actual stage by the user. In order to understand the relative arrangement position of each input device and output device arranged at a glance, it is displayed in a display form that gives an overview of the entire stage where they are arranged. Is done. In this embodiment, microphone displays Ma to Md are displayed as graphic images corresponding to the microphone 7A, and speaker displays Da to Dd are displayed as graphic images corresponding to the monitor speaker 8A.

  The graphic images (microphone displays Ma to Md, speaker displays Da to Dd) displayed on the multipoint touch display 6C may be displayed in a shape that allows the device corresponding to the display to be understood at a glance. In addition, not only graphic images but also auxiliary character displays (such as MONITOR A to D and MIC a to d in the figure) representing corresponding devices may be displayed in the vicinity of each graphic image. Also, depending on the range of volume levels that can be controlled in each actual device (that is, the amount of control), the one with a relatively large control amount is large and the one with a relatively small control amount is small. The graphic images may be displayed with different sizes (those with the same control amount are displayed with the same size).

  The user arbitrarily touches any one of the microphone displays Ma to Md or the speaker displays Da to Dd displayed on the multipoint touch display 6C, thereby making an input related to the device corresponding to the touched display. Only the signal can have its signal path displayed on the screen as a signal line. The signal line of the input signal to be displayed is determined according to the mixing input / output path (setting information related to the signal transmission source and output destination) of the musical sound signal determined in advance in the mixer body Z. For example, in the mixer main body Z, signals to be mixed are input signals input from all four microphones (MICs a to d), and the monitor speaker C (MONITOR) is used as an output destination of the mixing signal obtained by mixing these input signals. When the setting information C) is assigned to the monitor speaker C (MONITOR C) from the microphone displays Ma to Md corresponding to the four microphones (MIC a to d) as illustrated in accordance with the setting information. Only the four signal lines L1 to L4 heading to the corresponding speaker display Dc are displayed. Thereby, regarding the monitor speaker C (MONITOR C), the correspondence relationship between the transmission source and output destination of the music signal to be mixed is shown.

  The signal lines L1 to L4 are displayed in a predetermined display mode corresponding to the volume level currently set in the mixer main body Z. Here, the display thicknesses (displays) of these signal lines L1 to L4 are displayed. The width is varied according to the volume level. For example, the higher the volume level set, the thicker the signal line is displayed. For example, in the figure, the display thickness of the signal line L3 is displayed thicker than the display thickness of the signal line L1, but this is input from the microphone a (MIC a) reflected in the monitor speaker C (MONITOR C). This indicates that the volume level of the input signal from the microphone b (MIC b) reflected on the monitor speaker C (MONITOR C) is larger than the volume level of the signal. When the volume level is set to “0”, such as when muted, the signal line is displayed as a broken line (dotted line) instead of a solid line (in the figure, the signal line L4 corresponds).

  As described above, when the user touches any one of the speaker displays Da to Dd corresponding to the desired output device for which the volume level adjustment is desired, the input is made to the monitor speaker 8A corresponding to the touched speaker display Da to Dd. Since the signal path of the input signal being displayed is displayed in a different display mode depending on the volume, the user is any microphone 7A whose output destination is the monitor speaker 8A corresponding to the touched speaker display Da to Dd, and It is possible to intuitively grasp from the screen display how much volume level the input signal is reflected in the output signal output from the monitor speaker 8A for each microphone 7A.

  On the other hand, when the user touches any one of the microphone displays Ma to Md corresponding to the desired microphone 7A whose volume is to be adjusted, the illustration is omitted, but it corresponds to the touched microphone display Ma to Md. Only the signal paths of all the input signals output from the microphone 7A to the monitor speaker 8A are displayed in different display modes according to the volume. In this case, since one to a plurality of signal lines based on one touched microphone display Ma to Md are displayed toward one to a plurality of speaker displays Da to Dd, respectively, the user has touched. Using the microphone 7A corresponding to the microphone displays Ma to Md as a transmission source, it is possible to intuitively grasp from the screen display which volume level the microphone input to the microphone 7A is input to which monitor speaker 8A. it can.

  The user can change the volume level of the input signal set in the mixer body Z by performing a predetermined touch operation on the screen according to the displayed signal line. That is, the volume level of an input signal input from a desired input device can be changed by performing a touch operation on the screen, and the digital signal processing circuit DP is controlled to perform signal control based on the changed volume level. Can be instructed. In the multi-point touch display 6C, as shown in FIG. 2, the predetermined touch operation is performed by sandwiching (stranding) the signal lines L1 to L4 of an arbitrary input signal whose volume level is to be changed as shown in FIG. This is an operation of touching (point A and point B in the figure) and shortening or extending the distance H between the two touched points (between A and B). When an operation of extending the distance H between the two touched points (in this case, an operation of moving a finger in the direction of expanding the display width of the signal line L1), a setting for increasing the volume level can be performed.

  On the other hand, when an operation for shortening the distance H between two touched points (between A and B) (here, an operation of moving a finger in the direction of narrowing the display width of the signal line L1) is performed, the volume level is lowered. Settings can be made. When the volume level is changed in accordance with the operation mode, the display thickness of the operation target signal lines L1 to L4 is adjusted according to the change of the volume level (that is, according to the movement of the finger touching each of the two points). The display thickness is displayed as thick or thin as needed, and the change in the volume level is immediately reflected in the display of the signal lines L1 to L4.

Note that the display thicknesses of the signal lines L1 to L4 of the corresponding input signals displayed on the multipoint touch display 6C may be updated in accordance with a change in volume according to the operation of the operation element 4A.
Note that the operation element 4A may be automatically operated in accordance with a touch operation on the multipoint touch display 6C. For example, in the case of an operation element 4A composed of a motor-driven fader (so-called motor drive fader) that automatically slides the knob portion with a motor, it is adapted to the touch operation on the multipoint touch display 6C. The knob portion may be automatically slid and positioned at an appropriate position corresponding to the set volume.

In addition, by arbitrarily touching any of the microphone displays Ma to Md and the speaker displays Da to Dd displayed on the multipoint touch display 6C, the user can slide the touched finger on the screen, The figure image being touched may be moved to an arbitrary position on the screen (so-called touch and drag). In this case, it goes without saying that the signal lines L1 to L4 displayed in association with the moved graphic image are also displayed and updated so as to move appropriately in accordance with the movement of the graphic image.
In addition, as a method for obtaining whether or not a touch operation is performed on the multipoint touch display 6C and a screen position (specifically, coordinates) on the touched multipoint touch display 6C, a method using infrared light, a resistance There are various methods such as a membrane method and a capacitance method. Since any known technique may be used for each of these methods, description thereof is omitted here.

  Next, in accordance with the touch operation on the multi-point touch display 6C by the operator, the display mode (display thickness here) of the signal lines L1 to L4 is changed and the setting related to the signal control of the corresponding input signal is performed. “Main processing” in which (the volume level here) is changed and reflected in the output signal will be described with reference to FIG. FIG. 3 is a flowchart showing an embodiment of the main process. This “main process” is a process executed by the CPU 1 shown in FIG. 1, and is started when the mixing apparatus body is turned on and is finished when the power is turned off. Here, description will be made with reference to FIG. 2 where the microphone 7A is used as the input device and the monitor speaker 8A is used as the output device.

  First, step S1 corresponds to the relative arrangement positions of the actual microphone 7A corresponding to the input device actually disposed on the stage or the like and the actual monitor speaker 8A corresponding to the output device. The coordinates (display position) in the multipoint touch display 6C on which graphic images (microphone displays Ma to Md, speaker displays Da to Dd) are to be displayed are determined. This coordinate may be specified by the user as appropriate on the mixer main body Z side, or by specifying one of a plurality of templates representing the arrangement of graphic images prepared in advance. . Step S2 clears a predetermined volume register for storing each of the volume levels of a plurality of input signals transmitted from the microphones 7A to the monitor speakers 8A used when displaying the signal lines L1 to L4.

  In step S3, a predetermined operating flag is set to “FALSE”. This in-operation flag indicates whether or not the volume level of a desired input signal can be set according to a touch operation on the multipoint touch display 6C. In step S4, the selection of the microphone 7A or the monitor speaker 8A as a target for displaying the signal lines L1 to L4 of the input signal on the multipoint touch display 6C is canceled (the selected microphone 7A or the monitor speaker 8A is selected). Clear the selected selection register to be stored). Through the processing from step S1 to step S4, preparation for setting the volume level according to the touch operation on the multipoint touch display 6C is performed. At this time, only graphic images (microphone display Ma to Md, speaker display Da to Dd) corresponding to the microphone 7A or the monitor speaker 8A are displayed on the multipoint touch display 6C, and signal lines L1 to L4). Is not yet displayed.

  In step S5, it is determined whether or not the selection operation of the microphone 7A or the monitor speaker 8A has been performed. That is, whether a graphic image (microphone display Ma to Md, speaker display Da to Dd) corresponding to the microphone 7A or the monitor speaker 8A displayed on the multipoint touch display 6C as an operation by the operator is touch-operated. Determine whether or not. When it is determined that the selection operation of the microphone 7A or the monitor speaker 8A has been performed (YES in Step S5), the selected microphone 7A or the monitor speaker 8A is stored in a predetermined selection register, and each monitor speaker 8A is received from each microphone 7A. The volume level of the input signal to be transmitted to is set to the current volume level specified based on the operation of the operation element 4A for setting the actual volume (this is stored in a predetermined corresponding volume register). A signal line (not shown) from the selected microphone 7A to each monitor speaker 8A or a signal from each microphone 7A to the selected monitor speaker 8A according to a predetermined music sound signal mixing input / output path Lines L1 to L4 are represented by display thickness corresponding to the set volume level. (Step S6). On the other hand, when it is determined that the selection operation of the microphone 7A or the monitor speaker 8A is not performed (NO in Step S5), it is determined whether or not the release operation of the microphone 7A or the monitor speaker 8A is performed (Step S18). If it is determined that the microphone 7A or the monitor speaker 8A has been released (YES in step S18), a signal line (not shown) from the selected microphone 7A to each monitor speaker 8A, or the selected monitor speaker The signal lines L1 to L4 from each microphone 7A to 8A are erased (step S19).

  In step S7, it is determined whether or not the in-operation flag is “TRUE”. If it is determined that the in-operation flag is not “TRUE” (no in step S7), two points (A) that are closest to each other among the plurality of touched points on the multipoint display 6C. (Point, B point) is obtained (step S13). In step S14, whether the distance H between the two obtained points is within a predetermined distance and any one of the signal lines L1 to L4 passes between the two points (that is, the position of the two points is the signal line L1). To determine whether or not it is a position for sandwiching (stripping) any one of L4. When it is determined that the obtained distance H between the two points is not within a predetermined distance or that none of the signal lines L1 to L4 passes between the two points (between A and B) (No in step S14). ), The process proceeds to step S17. When it is determined that the obtained distance H between the two points is within a predetermined distance and any one of the signal lines L1 to L4 passes between the two points (yes in step S14), the touch is performed. For the line segment (AB) connecting the two points, the component in the normal direction with respect to the display direction of the signal line L1 straddling the two points is stored as a reference value (step S15). In step S16, the operating flag is set to "TRUE".

  When it is determined in step S7 that the operating flag is “TRUE” (yes in step S7), the touch operation is continued as it is for the two points that were previously touched on the multi-point touch display 6C. It is determined whether the two points are present (step S8). If the two points that are currently being touched are in the vicinity of the two points (points A and B) that were previously touched, it is determined that the two touch operations are continued. If it is determined that the touch operation is not continued (no in step S8), the operating flag is set to “FALSE” (step S9), and the process jumps to the process in step S17.

  On the other hand, when it is determined that the touch operation is continued (yes in step S8), the display direction of the signal line L1 straddling the two points with respect to the line segment (AB) connecting the two touched points. On the other hand, a change in volume level is obtained from the change in the length of the normal component from the reference value of the component in the normal direction (see step S15) (step S10). In step S11, the volume level is set by applying the obtained change in volume level to the volume level of the input signal in the signal path corresponding to the signal line L1, and signal control is performed based on the set volume level. To the digital signal processing circuit DP. The digital signal processing circuit DP controls the volume level of the corresponding input signal according to the instruction. In step S12, the display thickness of the signal line L1 corresponding to the corresponding input signal displayed on the multipoint touch display 6C is updated based on the updated (set) volume level.

  In step S17, the coordinates for displaying the graphic image corresponding to the selected microphone 7A or the monitor speaker 8A are updated according to the touch and drag operation of the microphone displays Ma to Md or the speaker displays Da to Dd, and the selected microphone is selected. This is reflected in the display position of the graphic image (microphone display Ma to Md, speaker display Da to Dd) corresponding to 7A or the monitor speaker 8A and the display of the signal lines L1 to L4. When the process of step S17 is completed, the process returns to the process of step S5, and the processes from step S5 to step S17 are repeatedly executed.

  As described above, when the graphic image corresponding to the input device and the output device is displayed on the multipoint touch display 6C and the user selects an arbitrary graphic image, the input signal of each device related to the graphic image is displayed. The route is displayed as a signal line having a display thickness corresponding to the set volume level. Then, the volume level is changed in accordance with a touch operation that expands or narrows the display width of the displayed signal line, and the input signal is controlled by the digital signal processing circuit DP in accordance with the change in the volume level. It was reflected in the output signal. In other words, the user can control the volume level of the input signal for any device by simply touching the display on the screen in a display state overlooking the arrangement of the entire device. The operator can intuitively understand the signal control information from the display, such as how much the operation can affect the input signal and how much change can be applied to the input signal. The volume level control of the signal can be performed happily.

  In addition, it is projected from a projector or the like separately provided on a mixing console such as a prompter or a rear projector, as well as a display that can emit light and display itself, such as the multi-point touch display 6C described above. It may be a display panel that can display the information. Moreover, the organic EL display etc. which were comprised using organic EL (abbreviation of Electro Luminescence) etc. may be sufficient. When such an organic EL display is used, it is possible to display by emitting light without providing a light source, so that the display can be formed thinner. Furthermore, displaying a graphic image and characters on the multipoint touch display 6C is not limited to electronic control, but may be based on quasi-optical control such as a hologram. In other words, any device can be used as long as it can be displayed and detected by a touch operation.

  The multipoint touch display 6C is not limited to a flat display, and may be a three-dimensional display. A display example in this case is shown in FIG. FIG. 4 is a conceptual diagram showing an example of screen display on the multipoint touch display 6C capable of stereoscopic display.

  Also in this case, graphic images (microphone displays Ma to Md, speaker displays Da to Dd) are displayed in a planar manner on the multipoint touch display 6C. However, in the illustrated example, since three-dimensional models (speaker models Ea to Ed, microphone models Fa to Fd) separately prepared by the user are placed on each graphic image, their displays are not visible. . In this case, the signal line is displayed when any one of the speaker models Ea to Ed and the microphone models Fa to Fd is touched. In addition to changing the display thickness of the signal line according to the sound volume level, the sound volume is also displayed. The signal lines are three-dimensionally displayed so as to undulate in the vertical direction of the screen according to the level (see L1 ′ and L3 ′). The larger the volume level, the thicker the display thickness and the three-dimensional display so as to increase the undulations. As a specific example, for example, the multipoint touch display 6C is configured to have a configuration in which a large number of solenoids are arranged under a screen formed of a member that expands and contracts, and a part of the large number of solenoids according to the volume level. The signal lines are displayed three-dimensionally by moving the screen up and down by driving up and down (those arranged in a place overlapping the signal line display). The signal line itself is projected on the screen by a projector provided separately. Similarly to the example shown in FIG. 2, the user performs the predetermined touch operation as described above on the screen for the three-dimensionally displayed signal lines (L1 ′, L3 ′), The volume level of the input signal set in the mixer body Z can be changed. Of course, the digital signal processing circuit DP controls the input signal according to the change in the volume level and reflects it in the output signal.

In addition, the display mode of the signal line according to the sound volume level is not limited to the display thickness and the undulation size described above. For example, the display mode may be a broken line (dotted line) in which the luminance when displaying the signal line, the shade of the display color, or the color tone changes from a cold color system to a warm color system, and the display interval changes. In this case, it is preferable to define different display modes for each predetermined volume level range.
In addition, the path | route at the time of displaying a signal line is not restricted to the linear display which connects the shortest distance as illustrated. For example, it may be a curve display or a display combining a plurality of straight lines.

Needless to say, the various settings related to signal control are not limited to the above-described volume level control of the input signal. Further, the setting is not limited to the setting related to the musical tone control, and may be the setting related to the video control.
During the touch operation on the multipoint touch display 6C, the parameter name to be changed and the current control value (volume level, etc.) are automatically displayed on the display 5A or the multipoint touch display 6C. You may be able to do that. In this case, the user can check the display 5A or the multi-point touch display 6C as necessary, so that it is possible to more clearly check what is being set and how to set it according to the display. is there.
