  By the way, the applicant has proposed the following mixer (unpublished Japanese Patent Application No. 2005-76684). In this mixer, a channel selection operator for selecting one channel from a plurality of channels and a group selection for grouping a plurality of channels by n (n is an integer of 2 or more) and selecting one from these groups An operator is provided. On the operation panel, an allocated channel strip unit arranged in the left-right direction and allocated channel strips arranged in front of the display unit and having an operator for setting parameters for one channel, and the display unit There is provided a parameter operation unit which is arranged on the left hand and includes a plurality of assignment knob operators for setting parameters for one selected channel. Then, a corresponding group is selected according to the operation of the group selection operator, n channels of the selected group are allocated to n allocated channel strips of the allocated channel strip unit, and a plurality of the n channels are selected. A group screen for displaying the parameter setting status is displayed on the display unit so that a display area for a plurality of parameters assigned to the assigned channel strip is arranged at a position above each assigned channel strip. Further, according to the operation of the channel selection operator, the corresponding channel is selected, and a plurality of parameters of the selected channel are assigned to a plurality of allocation knob operators of the parameter operation unit, and a plurality of allocation knob operations of the parameter operation unit are performed. The display elements of the knob operator are displayed in an arrangement corresponding to the arrangement of the child elements, and a parameter screen for displaying the setting status of a plurality of parameters of the channel is displayed on the display unit.

  A user interface with good operability for controlling parameter values suitable for such a mixer is desired.

  By the way, in such a mixer, a large display is required to display all the parameters of each channel in the area for displaying the parameter setting status of each channel on the group screen. It may be possible to reduce the size of the display unit by switching and displaying some parameters, but in that case, it is necessary to check the parameter value while checking which parameter is displayed, which reduces operability. . Therefore, it is not preferable to switch and display parameters on a group screen that displays multiple channels, and it is desirable that the display contents of each channel be fixed.

  Further, when the parameter value is changed by dragging the digital mixer with a touch display, there is a problem that it is difficult to set a desired value, and the finger is rubbed, so that the display is easily soiled. It is desirable that the parameter value is changed not by a touch screen but by a separate parameter operator.

  Further, among the parameters displayed on the group screen displaying the parameter setting status of a plurality of channels, there are a parameter that is operated relatively frequently and a parameter that is operated relatively less frequently. It is desirable to reduce the size of the display by hiding parameters that are less frequently operated.

  An object of the present invention is to provide a digital mixer having an easy-to-operate user interface that can easily control parameter values even with a display of a limited size. An object of the present invention is to realize high operability in consideration of a parameter having a high frequency and a parameter having a relatively low frequency of operation.

In order to achieve this object, the invention according to claim 1 is a digital mixer, and corresponds to any one of a plurality of input channels or output channels, and an operator for setting a parameter of the corresponding input channel or output channel is provided. A plurality of channel strips, arranged on the operation panel in a position close to the display device and facing the operator with respect to the display device, configured to be able to assign any input channel or output channel, and assigned K assigned channel strips having an operator for setting a parameter of the selected channel, kch selection means for collectively selecting k channels among the plurality of input or output channels according to a user operation, Allocating means for allocating the k channels selected at once by the kch selecting means to the k allocated channel strips. Vessel, the Show kch strip screen for displaying a representative parameter of the plurality of signal processing modules the k for each ch selected by the kch selection means. Further, it comprises parameter selection means for selecting any one of the parameters displayed on the kch strip screen in response to a user operation. (1) The first type representative parameter is selected by the parameter selection means. Or when the already selected second type representative parameter is reselected, the selected representative parameters of k channels assigned to the k assigned channel strips are displayed. A kch window is superimposed on the kch strip screen and displayed as a pop-up, and the displayed k selected representative parameters are respectively assigned to any of the operators of the k assigned ch strips. 2) When the parameter selection means selects the unselected second type representative parameter, assigning the selected representative parameters of the k channels assigned to the k assigned channel strips to the operators included in the assigned channel strips without popping up a ch window, respectively, (3) In a state where the kch window is not open on the kch strip screen, the representative of the second type of k channels assigned to the k assigned ch strips in a selected state on the kch strip screen. A parameter is assigned to each of the operators included in each assigned channel strip. In accordance with a user operation on each operator of the k assigned channel strips, the parameter value assigned to each operated operator is controlled to update the parameter stored in the storage means. .

The invention according to claim 2 is the digital mixer according to claim 1, wherein the kch strip screen displays the first type representative parameter and the second type representative parameter separately. It is characterized by that.

According to a third aspect of the present invention, in the digital mixer according to the first or second aspect, the display is a contact position detection type display capable of detecting a contact position, and the parameter selection means includes the display characterized in that for the region corresponding to each representative parameter displayed is to select a representative parameter corresponding in response to detecting the contact operation.

  According to the present invention, if the selected operation is the first type parameter, the parameter window of the parameter is opened by a single operation, and various controls relating to the parameter can be performed. In order to switch the parameter controlled by the parameter operator to another parameter, the parameter window must be closed once. However, since the frequency of the first type parameter is low, the frequency of the operation is low. On the other hand, if the selection operation is the second type parameter, the parameter operated by the parameter operator (the parameter in the selected state) is switched by one operation. Then, if necessary, the parameter window can be opened by performing another selection operation. That is, for the second type parameter with high operation frequency, the parameter controlled by the parameter operator can be switched in order by one operation.

  Further, when a kch window of a certain representative parameter is opened, the 1ch window, kch window, and all ch windows of the representative parameter can be freely switched. That is, it is possible to efficiently perform detailed setting focusing on 1ch of the representative parameter, setting with continuity from the kch strip screen, and setting over all channels while going back and forth between those screens.

  Furthermore, the touch display is used for parameter selection operations and is not used for parameter value change operations. The parameter value is changed by a separately provided parameter operator. That is, since it is not necessary to perform a drag operation on the touch display, the surface of the display is difficult to get dirty.

A set of a plurality of channels that can be called to the assigned channel strip unit 424 by the selection switches 551 to 558 and 561 to 564 is called a group.

  FIG. 6 shows a display example of an 8ch strip screen displayed on the display 423 of FIG. The 8ch strip screen is a screen that displays the setting status of each channel (for 8 channels) of the group selected by each of the selection switches 551 to 558 and 561 to 564 of the G selection operation unit 426 described with reference to FIG. When any of these selection switches is turned on, the corresponding 8ch strip screen is displayed. FIG. 6 shows a display example of the display unit 423 when the selection switch 551 is turned on and the input channel strip unit 411 is allocated to the allocated channel strip unit 424. An area 600-1 to 600-8 displays the parameter setting status of each channel (here, the first to eighth input channels) of the selected group. The display areas 600-1 to 600-8 are displayed so as to correspond to the respective channel strips 530-1 to 530-8 of the allocated channel strip portion 424 provided on the lower side of the display unit 423 in the vertical direction. The

  In the display area for one channel, for example, 600-1, 601 is the channel number of the input channel, the name given to the channel and the display of the input system to be input to the channel, and 602 is an input patch connected to the input channel. A knob indicating the set value of the analog gain of the head amplifier (inside the A input in FIG. 2) and display of the value, 603-1 to 603-4 indicate the setting status of various signal processing in the input channel. It is an area. The knob 602 is a display imitating the knob of the rotary encoder, and is displayed as if the knob is rotated by an amount corresponding to the level setting value. The signal processing setting statuses in the areas 603-1 to 603-4 indicate the parameter setting statuses of the HPF 302, PEQ 303, and first and second DYNAMICS 304 and 305 of the channel described in FIG. 3 in order. 3 is not displayed on the screen of FIG. This is because it is evaluated that the parameters are not as important as those displayed on the strip screen. However, the ATT 301 can be set in a parameter window described later. INS and D. on the right side of region 603-1. The rectangle written OUT is an INS button and D.D. Indicates the OUT button. These buttons can be turned on / off by touching (touching with a finger or the like). The INS button is a button for setting validity / invalidity of insertion of the internal effector not shown in FIG. The OUT button is a button for setting validity / invalidity of direct output of a signal from the input channel to the output patch 213 in FIG.

  Reference numerals 604-1 to 604-16 are knob displays indicating the set values of the transmission levels of signals output from the input channel to each of the 16 MIX buses (206 in FIG. 2) (knob 604 -n is MIXn ( Corresponds to the nth MIX bus). Reference numeral 605 denotes a knob display indicating a set value of left and right localization (pan / panning) when a signal is output in stereo from the input channel to a stereo bus (207 in FIG. 2) or the like. Signal processing relating to the transmission level and panning is performed at 308 in FIG. The rectangles written ST and MONO on the right side of the knob 605 indicate the ST button and the MONO button. By touching these buttons and turning them on / off, the signal output from the input channel to the L and R buses of the stereo bus 207 is turned on / off (ST button), and the signal output to the C bus is turned on. / OFF (MONO button).

  For convenience of explanation, the numbers given to the display elements in the display area 600-1 are also used for the display elements in the display areas 600-2 to 600-8. For example, when the knob 604-1 in the display area 600-2 is referred to, when the display area 600-2 and the display area 600-1 are overlapped, the display area that overlaps the knob 604-1 of the display area 600-1. It shall refer to the knob of 600-2. The same applies to the ch strip described in FIG.

  By touching any of the knobs 602, 604-1 to 604-16, 605, the knob is selected. A cursor 606 is set to the selected knob. The cursor 606 has a ring shape that overlaps the knob display. In particular, even if any knob of any channel in the display areas 600-1 to 600-8 of each channel is touched, the knobs at the same position in the display areas 600-1 to 600-8 of all the channels are simultaneously arranged in parallel. Selected (note that the operation when the knob already in the selected state is touched again will be described later). For example, when the knob 604-3 in the display area 600-2 is touched, all the eight knobs 604-3 in the display areas 600-1 to 600-8 are selected. At this time, the eight cursors displayed in parallel are called 8ch rings. The parameter values corresponding to the knobs selected in parallel can be independently changed by the rotary encoders 536-1 to 536-8 of the assigned channel strips 530-1 to 530-8. In the parameter operation unit 422 described above, focusing on one selected channel, a plurality of parameters of the channel can be operated in parallel, whereas in the rotary encoder 536, one parameter selected by touching is selected. Focusing on (for example, the transmission level to any one of the MIX buses 206), the parallel operation of the parameters for 8 channels allocated to the allocated channel strips 530-1 to 530-8 can be performed. Thus, for example, for a transmission level, a parallel operation of a transmission level from a focused input channel to a plurality of MIX buses, and a parallel operation of a transmission level from eight input channels to a focused MIX bus. Thus, it is possible to easily adjust the balance in two ways from the channel side and the parameter side.

  When any knob is selected in the display area 600-1 to 600-8, touching any button executes a function corresponding to the button operation. There shall be no change. Note that the touch of the knob not only selects the eight knobs at the same position as that knob, but at the same time, the channel assigned to the assigned channel strip to which the touched knob belongs is displayed on the parameter operation unit 422. The channel to be controlled may be selected. Further, the function of selecting the ch to be controlled in conjunction with each other may be enabled / disabled as desired by the user.

  Reference numeral 620 denotes a display area such as a button used when performing various settings of the mixer and a meter indicating the L / R and C output signal levels of the stereo output channel. Reference numeral 621 denotes a button for switching the operation mode of the electric fader 105 in FIG. 1 (eg, 535 in FIG. 5). When the button 621 is in the OFF state, the “normal mode” is set, and the electric fader of each channel strip is a signal level (gain) at the position of the fader 307 in FIG. 3 as a fader for controlling the signal level of the corresponding channel. To control. When the button 621 is in the “ON” state, the “send mode” is set, and the electric fader of each channel strip transmits the transmission level (308 in FIG. 3) to the selected bus as a transmission level control fader from the corresponding channel. Gain). In the “send mode”, a button for selecting one (or pair) bus from the 16 MIX buses and the stereo bus is displayed in the meter (METER) display area of the area 620. By operating the button, it is possible to select a bus whose transmission level is to be controlled by the electric fader. Reference numeral 630 denotes a display of the currently called scene. The number of the scene can be increased / decreased, and scenes can be recalled and stored using the controls of the scene operation unit 425 (FIG. 4) below the display 630. Reference numeral 640 denotes a display of the currently selected channel. Here, the input channel “CH1” with the name “Vocal” is selected. This channel selection can be performed by the SEL switch of the channel strip, and can also be performed by buttons arranged on the left and right sides of the 640.

  In FIG. 6, the 8ch strip screen of the first to eighth input channels displayed when the selection switch 551 is turned on has been described as an example, but when the other selection switches 552 to 558 and 561 to 564 are turned on. The displayed strip screen has the same configuration. However, when the selection switch 557 is turned on, the display for four channels to the left (600-1 to 600-4) is displayed, and when the selection switch 558 is turned on, the display for two channels is displayed to the left (600-1 to 600-2). However, each will be done. Further, when the selection switches 558 and 561 to 564 are turned on, the output side channels are displayed. However, since the contents of signal processing are slightly different from those of the input channels described with reference to FIG. The display of the partial areas 601 to 606 of the display area for 1 ch is different from that in FIG. For example, since the input source of the signals of these channels is a bus, there is no display corresponding to the head amplifier 602, and there are no INS button 603-1, knob 605, ST button, MONO button, etc. In addition, the knobs for controlling the transmission level display eight knobs 604-1 to 604-8 corresponding to the eight matrix buses 211 as signal output destinations only for the stereo output channel and the MIX output channel.

  FIG. 7 shows a display example of the selected channel screen displayed on the display unit 423 of FIG. The SEL switch (such as 531 in FIG. 5) of any of the channel strips of the input channel strip units 411 to 416, the stereo input channel strip unit 417, the stereo output channel strip unit 418, and the assigned channel strip unit 424 in FIG. Then, the channel corresponding to the channel strip is selected as the target channel for parameter operation in the parameter operation unit 422. At this time, the selected channel is displayed as a screen for displaying the detailed parameter setting state of the selected channel. A screen is displayed. The selected channel screen in FIG. 7 shows the selected channel screen for the first channel among the input channels. Here, the description has been made assuming that the screen is switched to the selected channel screen by operating the SEL switch, but it is assumed that there is an option that allows the user to set the enable / disable of the function to switch to the selected channel screen (the channel to be operated is selected). )

  Reference numeral 701 denotes a display area of 16 knobs 701-1 to 701-16 indicating the transmission level from the input channel to the 16 MIX buses 206. A PRE button and an ON button are provided on the right side of each knob. Reference numeral 702 denotes a knob display area indicating the gain level of the head amplifier provided in the preceding stage of the input channel. Reference numerals 703 to 706 denote partial areas for displaying the parameter setting statuses of the HPF 302, the PEQ 303, and the first and second DYNAMICS 304 and 305 of the input channel described in FIG. In each of the partial areas 703 to 706, a necessary number of knobs are displayed. Reference numeral 707 denotes a knob display area indicating a set value of panning of an output signal from the input channel to the stereo bus (207 in FIG. 2). In addition, a partial area for displaying the parameter setting status for the channel is displayed as necessary. The display of 620, 621, 630, 640 on the right side is the same as the strip screen of FIG.

  The arrangement of the knobs displayed in the partial areas 701 to 707 (however, the partial areas 705 and 706 are only the knobs for adjusting the left side THRESHOLD) is arranged on the parameter operating section on the left side of the display 423 described with reference to FIG. This corresponds to the arrangement of the rotary encoder 422, and the parameter value of the corresponding knob can be changed by operating the rotary encoder of the parameter operation unit 422. Since the layout corresponds, the operation is easy to understand.

  Buttons are provided as necessary in each partial area of the selected channel screen. For example, rectangles written as ST and MONO in the area 707 indicate the ST button and the MONO button. Touching the ST button part turns on / off the signal output from the input channel to the L and R buses of the stereo bus 207. Touching the MONO button turns on the signal output to the C bus. Can be turned off.

  In FIG. 7, the selection channel screen of the first input channel has been described as an example, but the selection channel screens of other channels have the same configuration. However, the display of the partial areas 701 to 707 and the like may be different from that in FIG. 7 depending on the configuration of ch.

  Here, switching of the screen by the push operation event of the rotary encoders of the assigned channel strip unit 424 and the parameter operation unit 422 will be described. When one of the above rotary encoders is pressed down, if the current strip screen is displayed, the last selected channel screen (which has been saved) is displayed. If the currently selected channel screen is displayed, the last screen is displayed. Switch to the group screen that has been saved (the one that has been saved). As a result, the screen can be easily switched while the rotary encoder is touched. For example, when the operation is normally performed on the group screen but only a predetermined parameter of a certain channel is to be confirmed and corrected, it is convenient to use a screen switching function by a push operation event of the rotary encoder. Even if the screen is switched, the functions of the operators of the assigned channel strip unit 424 and the parameter operation unit 422 do not change. Therefore, after pushing the rotary encoder of the parameter operation unit 422 and confirming the parameters that can be changed by the rotary encoder on the selection channel screen, the rotary encoder is pushed again and the group screen is displayed. Fine adjustments can be made.

  Both the strip screen in FIG. 6 and the selection channel screen in FIG. 7 can be turned on / off or selected by touching the button or knob on the screen. However, the parameter value indicated by the knob cannot be changed by touching the screen, but is performed using a rotary encoder provided on the panel. Therefore, the parameter value of the knob does not change by touching the screen by mistake. It should be noted that in the operation of the strip screen, the selection channel screen, and the operation unit of each operation unit, the value of the corresponding parameter stored in the current memory is changed, and as a result, the changed parameter value is turned on / off of each button. This is reflected in the off state and the setting value of each knob. Note that the strip screen of FIG. 6 and the selection channel screen of FIG. 7 are screens that are the basis of operations, and are collectively referred to as a base screen.

  In order to facilitate understanding of the correspondence between the parameter operation unit 422 and the selected channel screen, and the correspondence between the assigned channel strip unit 424 and the group screen, the background color of the parameter operation unit 422 and the background color of the selected channel screen are set to the first color. A similar color may be used, and the background color of the assigned channel strip unit 424 and the background color of the group screen may be a second similar color different from the first similar color. As a result, it can be seen at a glance whether the currently displayed group screen or selected channel screen, and it can be easily grasped whether the parameter operation unit or the assigned channel strip unit is to be operated. Further, the knob display on the screen may be associated with the color of the rotary encoder knob.

  Next, the downward triangular mark and the double downward triangular mark displayed in each partial area of the strip screen of FIG. 6 will be described. These downward triangles or double downward triangles indicate that the partial area (except the part that is explicitly a button) functions as a button for selecting the parameter displayed in the partial area. It is a display which shows that it is the area | region which fulfills. The downward triangular mark area indicates that the parameter is “first type parameter”, and the double downward triangular mark area indicates that the parameter is “second type parameter”. When the first type parameter is selected (that is, when an area other than the button in the partial area where the first type parameter is displayed (partial area of the downward triangle) is touched), the detailed parameters related to the parameter are displayed. An 8ch parameter window for setting (hereinafter referred to as 8ch window) is displayed. When a second type parameter that is not in a selected state is selected (that is, when a region other than a button in a partial region (double partial region with a downward pointing triangle) where the second type parameter is displayed is touched), The second type parameter selected and operated this time is selected. When the second type parameter in the selected state is selected again, an 8ch window for performing detailed settings related to the parameter is displayed. For example, the area where the knobs 604-1 to 604-16 in FIG. 6 are displayed is a double downward triangular mark area, so the parameter of each knob displayed here (the send level to each MIX bus) ) Is a second type parameter. Therefore, if you touch a knob that is not in the selected state (even if you touch the background area around the knob, it is assumed that the nearest knob is touched), the 8ch ring moves and the touched position Eight knobs are selected. When the knob in the selected state is touched again, an 8ch window is displayed. It is assumed that the first type parameter of the downward triangle mark is relatively infrequent and the second type parameter of the double down triangle mark is relatively frequently used. Since the first type parameter must be changed in the parameter window, switching of the parameter is troublesome, but there is no problem because the frequency of use is low. The type 2 parameter can be changed by switching the selection state on the base screen without opening the parameter window.

  FIG. 8 shows that the 8th window 801 is displayed when the first DYNAMICS (first type parameter) 603-3 (802 in FIG. 8) of the display 600-4 in the fourth column is selected on the 8ch strip screen of FIG. Show the state. There are multiple types of 8ch windows. The 8ch window to be displayed is determined according to the selected first type or second type parameter. FIG. 10A shows an 8ch window of DYNAMICS1. FIG. 10B shows an 8ch window displayed when the partial area 603-1 or 603-2 of any channel of FIG. 6 is touched. FIG. 11 shows an 8ch window displayed by selecting one of the knobs 604-1 to 604-16 indicating the transmission level from each channel to each MIX bus.

  The same applies to the downward triangles displayed in the partial areas of the selected channel screen in FIG. However, while the parameter window displayed from the 8ch strip screen of FIG. 6 is an 8ch window, the parameter window displayed from the selected channel screen is a 1ch window (1ch parameter window). The 1ch window is a window for performing more detailed setting of the parameter related to the selected channel, and there are a plurality of types according to the selected parameter. For example, FIG. 9A shows a 1ch window displayed when the partial area 705 of DYNAMICS 1 in FIG. 7 is touched. (The partial triangle 705 indicating that the partial area 705 is the first type parameter is displayed. Therefore, when the partial area 705 is touched once anywhere in the partial area 705, the 1ch window of FIG. 9A is displayed. FIG. 9B shows a 1ch window displayed when the partial area 703 or 704 is touched on the selected channel screen of FIG. When any knob is selected in the partial area 701 of the knobs 701-1 to 701-16 indicating the transmission level to each MIX bus (or MATRIX bus) on the selected channel screen of FIG. It is assumed that an 8ch window (FIG. 11) indicating the transmission level to the MATRIX bus) is displayed. Since there are no detailed parameters for this transmission level to make a 1ch window, it is an 8ch window.

  Details of each parameter window will be described with reference to FIGS.

  FIG. 9A is a display example of the 1ch window 900 of the first dynamics (DYNAMICS 1 in FIG. 3). 901 is a heading indicating that this 1ch window is for setting detailed parameters related to DYNAMICS1, 902 is a button for closing this window, 905 is a default button, 906 is a 1ch button, 907 is an 8ch button, and 908 is ALL. Button. Reference numeral 911 is a display of a channel number and a channel name (which can be arbitrarily assigned by the user) indicating which channel this 1 channel window is, and 912 is a display of an icon simultaneously selected when the channel name is assigned ( (Not shown). Reference numeral 913 denotes a button for setting ON / OFF of DYNAMICS 1 in this channel. When the button 913 is turned on, DYNAMICS 1 functions effectively in the signal processing flow described with reference to FIG. When turned off, DYNAMICS1 only passes through the signal. Reference numerals 914-1 to 914-8, 915, 916, and the like indicate buttons and knobs for setting detailed parameters of DYNAMICS 1. In particular, knobs 914-1 to 914-8 indicate parameters that can be operated by encoders 536-1 to 536-8 at the bottom of the screen.

  Note that when only the base screen (FIGS. 6 and 7) is displayed and the parameter window is not displayed overlapping therewith, the encoders 536-1 to 536-8 display the 8ch ring on the 8ch strip screen (FIG. 6). When the parameter window shown in FIGS. 9 to 13 is displayed, the encoders 536-1 to 536-8 are assigned to the operators for setting the set parameters in the selected state. It is assumed that the operator switches to an operator for setting a predetermined parameter in the parameter window. When the parameter window is closed, the assignment of encoders 536-1 to 536-8 is restored.

  By touching the default button 905 to turn it on, the parameters of this channel's DYNAMICS 1 can be set to default values. The 1ch button 906 is grayed out and cannot be operated. When the 8ch button 907 is touched, the screen shifts to an 8ch window (FIG. 10A described later) regarding the dynamics 1 including the channel. When the ALL button 908 is touched, the screen shifts to an all ch window relating to the dynamics 1 (FIG. 12A described later).

  FIG. 9B shows a display example of a 1ch window 930 related to HPF and EQ (ATT, HPF and EQ in FIG. 3). Elements 931 to 938 at the bottom of the screen correspond to elements 901 to 908 in FIG. 9A, and their roles and functions are the same. The 8ch button 937 shifts to FIG. 10B, and the ALL button 938 shifts to FIG. 12B. Elements 941 to 943 are the same as the elements 911 to 913 in FIG. 944-1 to 944-8, 945, and 946 are buttons and knobs for setting detailed parameters of ATT, HPF, and EQ, and knobs 944-1 to 944-8 are encoders 536 at the bottom of the screen. This is a parameter that can be operated at -1 to 536-8.

  FIG. 10A is a display example of the 8ch window 801 of DYNAMICS1. The headline display 1001, the close button 1002, the 1ch button 1006, the 8ch button 1007, and the ALL button 1008 are the same as the 1ch window. Since this window 801 is an 8ch window, the 8ch button 1007 cannot be operated in gray-out display, and the 1ch button 1006 shifts to FIG. 9A and the ALL button 1008 shifts to FIG. 12A. .

  1010-1 to 1010-8 are displays corresponding to the 8 channels displayed on the original 8 channel strip screen in order. Display of one channel, for example, 1010-1 is a display 1011 of the icon and name of the channel, a display 1012 and 1013 of a graph indicating the setting status of the parameter, a knob 1014 indicating a representative parameter, and an on / off button 1015. The representative parameter is a parameter representing the function among a plurality of parameters necessary for realizing one of the signal processing elements (functions) shown in FIG. For example, in DYNAMICS1, THRESHOLD is a representative parameter. In the 8ch window, the representative parameters of each channel are displayed, and can be operated by corresponding encoders 536-1 to 536-8 in order. The on / off button 1015 is a button for designating validity / invalidity of the function specified by the heading 1001 in the channel, and is the same as the button 913 in FIG. 9A.

  Reference numeral 1020 denotes a cursor, which can be set to any channel by touching any of the displayed 8ch regions 1010-1 to 1010-8. By copying the parameter of DYNAMICS1 of the channel where the cursor 1020 is set by the copy button 1003, setting the cursor 1020 to another channel and touching the paste button 1004, the copied parameter of DYNAMICS1 can be pasted to that channel . With the default button 1005, the parameter of DYNAMICS1 of the channel where the cursor 1020 is set can be returned to the default value.

  FIG. 10B is a display example of an 8ch window 1030 of ATT / HPF / EQ. Elements 1031 to 1038 at the bottom of the screen correspond to elements 1001 to 1008 in FIG. 10A, and their roles and functions are the same. The 1ch button 1037 shifts to FIG. 9B, and the ALL button 1038 shifts to FIG. 12B. The displays 1040-1 to 1040-8 and the cursor 1050 corresponding to 8ch displayed in order on the original 8ch strip screen are the same as those in FIG. Among the elements for each channel, 1041 is an icon and a channel name display, and 1042 to 1046 are buttons and knobs for setting detailed parameters of ATT / HPF / EQ. Since the 8ch window 1030 is a collection of a plurality of signal processing elements, a button 1044 for turning on / off the HPF and a button 1046 for turning on / off the EQ are provided independently. In ATT / HPF / EQ, the representative parameter is EQ1045.

  In this window 1030, both the knob 1042 corresponding to the ATT level of each channel and the knob 1043 corresponding to the frequency of the HPF are displayed. Therefore, when the knob 1042 of any channel is selected, the same knob of each channel is displayed. 1042 is displayed with increased brightness (knob 1043 is grayed out at this time) and can be operated with encoders 536-1 to 536-8. On the other hand, if the knob 1043 of any channel is selected, the same for each channel is displayed. The knob 1043 is displayed with increased brightness (the knob 1042 is grayed out at this time) and can be operated by the encoders 536-1 to 536-8.

  FIG. 11 is a display example of an 8ch window 1100 of MIX4SEND (sending level to MIX bus 4). Since this is the transmission level to the MIX bus 4, this is a window that opens when the knob 604-4 of any channel in FIG. 6 is touched again in the selected state. Elements 1101 to 1108 at the bottom of the screen correspond to elements 1001 to 1008 in FIG. 10A, and their roles and functions are the same. The ALL button 1108 shifts to FIG. Note that there is no parameter for displaying in detail in the 1ch window for the send level to the MIX bus, so there is no corresponding 1ch window. Therefore, the 1ch button 1106 is grayed out together with the 8ch button 1107. The displays 1110-1 to 1110-8 and the cursor corresponding to 8 ch displayed on the original 8 ch strip screen are the same as those in FIG. The elements 1111 to 1114 for each channel are the same as the elements 1011 to 1015 in FIG. An on / off button 1113 can switch on / off of signal transmission from the channel to the MIX bus 4. The sending level indicated by the knob 1114 can be manipulated by the encoders 536-1 to 536-8. The representative parameter is a numerical display of the transmission level.

  FIGS. 12A, 12B and 13 show the all_ch window of the parameter windows. These cannot be opened directly from the base screen, but are opened by touching the ALL button of the 1ch or 8ch window.

  FIG. 12A shows a display example of an all_ch window 1200 related to DYNAMICS1. An icon 1212 of each channel from the first to 48th channels, a channel name 1211 (channel numbers may be displayed simultaneously), and a graph display 1213 of DYNAMICS1 representative parameters (may be displayed numerically) are displayed. . By touching an arbitrary channel portion, the cursor 1220 is set to that channel.

  At the bottom of the window, a parameter name display 1201, a close button 1202, a copy button 1203, a paste button 1204, a default button 1205, a 1ch button 1206, an 8ch button 1207, and an ALL button 1208 (grayed out so that they cannot be turned on) Is displayed). The DYNAMICS1 parameters of an arbitrary channel can be copied and pasted to another channel by the cursor 1220, the copy button 1203, and the paste button 1204, as in the 8ch window. Similarly to the 8ch window, the default button 1205 can return the parameters of the DYNAMICS 1 of any channel to the default state. Similarly to the other parameter windows, the 1ch button 1206 and the 8ch button 1207 can be used to shift to a 1ch window or an 8ch window.

  FIG. 12B shows a display example of an all_ch window 1230 related to ATT / HPF / EQ. The icons 1242, the channel names 1241, and the representative parameter graph display 1243 of the channels 1 to 48 are the same as those in FIG. Here, the EQ setting state is displayed as a graph as a representative parameter. Elements 1231 to 1238 at the bottom of the screen correspond to elements 1201 to 1208 in FIG. 12A, and their roles and functions are the same.

  FIG. 13 shows a display example of the all_ch window 1300 related to MIX4SEND (transmission level to the MIX bus 4). The icons 1312, the channel names 1311, and the representative parameter display 1313 of each channel from the first to the 48th channels are the same as in FIGS. 12A and 12B. Here, the transmission level from the channel to the MIX bus 4 is numerically displayed as a representative parameter. In addition, a PRE button is displayed. Elements 1301 to 1308 at the bottom of the screen correspond to the elements 1201 to 1208 in FIG. 12A, and their roles and functions are the same.

  As described above, the same parameters can be transferred to each other between the 1ch window, 8ch window, and all_ch window using the 1ch button, 8ch button, and ALL button. Further, when the channel where the cursor is set in the all_ch window is touched again, the corresponding 8ch window is displayed. When the channel where the cursor is set in the 8ch window is touched again, the corresponding 1ch window is displayed.

  In the 1ch window, detailed parameters can be referred to and set for one channel. In the 8ch window, representative parameters for 8ch can be referenced and set in parallel. In the all_ch window, the representative parameters of all channels can be referenced. For example, in the case of DYNAMICS1, the parameters can be copied and pasted between arbitrary channels. In the 1ch window and 8ch window, it is possible to specify ON / OFF of the signal processing element function of each channel. In the all_ch window, the encoders 536-1 to 536-8 are not effective, but for example, the representative parameters can be changed by the encoders 536-1 to 536-8 for the designated 8 channels for one line. Good.

  FIG. 14 is a flowchart of the touch screen process in the 8ch strip screen (FIG. 6). This process is started when an arbitrary position is touched on the 8ch strip screen. It is determined whether the region operated in step 1401 is the first type parameter, the second type parameter, or another region. (Note that if the button is operated, the process is terminated according to the operation of the button, but it is omitted in FIG. 14.) In the case of the first type parameter, 8ch in step 1402 The ring is erased, and an 8-channel window is displayed with the parameter touched in step 1403 as a representative parameter. When the second type parameter is touched, it is determined in step 1404 whether the parameter is in a selected state. When not in the selected state, the 8ch ring is moved in step 1405. This is a process of moving the 8ch ring from the parameter previously displayed in the selected state to the position of the parameter touched this time. Next, in step 1406, the touch-operated parameter is set to the selected state (the parameter that was previously selected becomes the non-selected state). If the parameter touched in step 1404 is in the selected state, the 8ch ring is deleted in step 1407, and an 8ch window with the parameter touched in step 1408 as a representative parameter is displayed. When the touch operation is performed in another area in step 1401, the 8ch ring is deleted in step 1409, and a parameter window corresponding to the area is displayed in step 1410.

  FIG. 15A is a flowchart of 8ch encoder processing. This process is a process executed when any of the eight operators (encoders) 536-1 to 536-8 on the lower side of the display screen is operated. In step 1501, it is determined whether the parameter window is currently displayed. If the parameter window is not open, in step 1502, the value of the parameter that is currently selected in the channel corresponding to the operated encoder is changed according to the operation of the encoder. In step 1503, it is determined whether the parameter is being displayed. If so, the display is updated in step 1504, and the process is terminated. When it is not being displayed, the process is terminated. If the parameter window is displayed in step 1501, the parameter value corresponding to the encoder in the window is changed in step 1505 in accordance with the operation of the encoder. Next, in step 1506, the display is updated, and the process ends.

  FIG. 15B is a flowchart of the selected channel encoder process. This process is executed when any of the operators (encoders) in the parameter operation unit 422 (FIG. 5A) on the left side of the screen is operated while the selected channel screen (FIG. 7) is displayed. Process. In step 1511, the value of the parameter corresponding to the encoder of the currently selected channel is changed according to the operation of the encoder. Next, in step 1512, if the parameter is being displayed, the display is updated in step 1513, and the process ends. If it is not being displayed, the process ends.

  FIG. 16 is a flowchart of the touch screen process on the selected channel screen. This process is executed when an arbitrary position in the screen is touched on the selected channel screen (FIG. 7). In step 1601, the touched area is determined. If it is an on / off button, the on / off of the parameter of the selected channel is reversed at step 1602, the display is updated at step 1603, and the process is terminated. If the touch operation is an AUX parameter (knob of the partial area 701), an 8-ch window (FIG. 11) using the parameter as a representative parameter is displayed in step 1604, and the process ends. If the touch-operated area is a parameter area other than AUX, in step 1605 a 1ch window with the parameter as a representative parameter is displayed and the process ends. If the touch operation has been performed on another area, a parameter window corresponding to the area is displayed in step 1606, and the process ends.

  FIG. 17 is a flowchart of the touch screen process in the 8ch window (FIGS. 10 and 11). This process is executed when a touch operation is performed in the 8ch window. Here, the process of moving the cursor, the process of the copy button, the paste button, and the default button are omitted. First, in step 1701, the operated area is determined. If it is an on / off button, the on / off of the parameter corresponding to the button operated in step 1702 is reversed, the display is updated in step 1703, and the process is terminated. If the touch operation is performed on the 1ch button, a 1ch window with the parameter as a representative parameter is displayed in step 1704 (this 8ch window is erased), and the process ends. If the ALL button has been touched, an all_ch window with the parameter as a representative parameter is displayed in step 1705, and the process is terminated. When the close button is touched, the window is closed in step 1706, and it is determined in step 1707 whether the base screen is an 8ch strip screen. If so, in step 1708, the 8ch ring is restored and the process ends. If the base screen is the selected channel screen, the process is terminated.

  The same applies to the touch screen processing in the 1ch window or the all_ch window.

  In the 8ch strip screen, when the second type parameter is touched once, the parameter is selected and the parameter window is opened by two touches. However, this need not necessarily be the case. For example, touching without pressing the shift key opens the parameter window regardless of whether it is the first type parameter or the second type parameter, and touching while holding the shift key touches the parameter only if it is the second type parameter. You may make it be in a selection state.

  In the above embodiment, 8 channels are handled as one unit, but the present invention is not limited to 8 channels. In the parameter window, ATT / HPF / EQ is summarized, but may be divided.

  When the representative parameter selection operation is performed, it is not always necessary to open a window corresponding to the open screen (selected channel screen, k channel (8 channel) strip screen). For example, it may be determined in advance which one of the 1ch window and the kch (8ch) window is opened for each selected parameter, or there are three types of windows: 1ch window, kch (8ch) window, and all ch windows. An operation element for switching to another window may be provided so that the window can be freely switched between the windows.

  In the above-described embodiment, a downward triangular mark indicating the first type parameter and a double downward triangular mark indicating the second type parameter are displayed in each partial area of the strip screen of FIG. However, the display is not limited to the triangular mark, and other forms of display may be adopted as appropriate. The display with the triangular mark or the like may be omitted, and the first type parameter and the second type may be omitted.
