Description

  The present invention relates to a mixing apparatus having a user-defined key for executing a pre-programmed function.

  Conventionally, the level and frequency balance of signals output from a large number of microphones or electric / electronic musical instruments are adjusted, mixed and sent to a power amplifier or various recording devices, mixed into several mixing groups, and effects or performances. There is known a mixing device for sending out to a player. The operator who operates the mixing device expresses the performance most appropriately by manipulating the volume and tone of each audio signal of instrument sounds and singing while monitoring the output signals of the various panel controls on the mixing console. The parameter value seems to be adjusted. The mixing apparatus includes at least a MIX bus that mixes a plurality of input channels and signals output from the input channels as an input signal system, and an output channel that is an output system that outputs the mixed signals. Each input channel controls parameters such as frequency balance and send level of input signals and outputs them to each MIX bus, and each MIX bus mixes the input signals and outputs them to the corresponding output channels. . Each output channel controls the frequency balance and level of the mixing signal from the MIX bus and outputs it to a speaker or the like.

  In such a mixing apparatus, the casing is made small by simplifying the panel surface by providing the minimum necessary controls on the panel surface. For this reason, the operator corresponding to all controllable parameters is not provided on the panel surface. Therefore, for a parameter for which no operation element is provided on the panel surface, a screen for setting the parameter is displayed on a display unit provided on the panel surface, and the parameter is set there. In this case, parameter setting must be performed after selecting the channel to be operated. Therefore, even when setting the same parameter for each channel, the selection of the channel to be operated and the parameter setting operation are performed only for the number of channels. The procedure for setting the parameters has to be repeated, and a lot of time has been spent.

  In order to solve this problem, a set by cell (SET BY SEL) function can be assigned to user defined keys provided on the panel surface. User-defined keys are keys for executing pre-programmed functions such as scene switching, talkback and turning on / off the built-in oscillator, and multiple user-defined keys that can be assigned different functions. Is provided. FIG. 17 shows a part of a list of functions that can be assigned to user defined keys. As shown in FIG. 17, functions such as a set by cell (SET BY SEL) function and a scene (SCENE) switching function can be assigned to user defined keys. In addition, a “NO ASSIGN” function is provided in order to clear the function assigned to the user defined keys. When there are a plurality of parameters in the assigned function, one of the parameters is selected as the operation target.

  The set by cell (SET BY SEL) function is a function for quickly setting the on / off parameter to be set for each channel. The on / off setting of the parameter to be operated is set to the channel strip of each channel. It can be set by operating the provided cell (SEL) key. The parameters to be operated in the SET BY SEL function are the parameter “SET [+ 48V]” that turns on / off the power supplied to the head amplifier, and the parameter “SET that switches between the positive and negative phases of the head amplifier” [φ] ”, parameter“ SET [PRE SEND] ”for switching the send position of the signal sent from the input channel to the MIX bus between post-fader (POST SEND) and pre-fader (PRE SEND), stereo bus from the input channel The parameter can be selected from the parameter “SET [TO STEREO]” for turning on / off the signal to be sent to and the parameter “SET [TO MONO]” for turning on / off the signal sent from the input channel to the mono bus.

  When the set-by-cell function is assigned to a user-defined key, when the assigned user-defined key is pressed, the set-by-cell (SET BY SEL) function program is started and the on / off parameter to be operated is set. The setting can be set for each channel by operating the cell (SEL) key of each channel. In this case, the set by cell (SET BY SEL) function assigns each parameter to be operated to a different user-defined key. However, if the parameter to be operated is individually assigned to the user-defined key as the operation target, the user-defined key is occupied by the set-by-cell function because the number of user-defined keys is limited. There was a problem that it could not be assigned. In addition, although a function assigned when a user-defined key is pressed is displayed, there is a problem that it is not known which parameter is assigned as an operation target to which user-defined key before pressing.

  Therefore, an object of the present invention is to provide a mixing apparatus that can effectively use a user-defined key with a limited number.

  In order to achieve the above object, the mixing device of the present invention can be assigned a user-defined key with a set-by-cell function that can be set with a channel selection key as an operation target on / off parameter set for each channel. When a user-defined key to which the set-by-cell function is assigned is operated, a selection screen for selecting a parameter to be operated on the display means is displayed, and channel selection is performed using the parameter selected on the selection screen as an operation target. The main feature is that it can be set with a key.

  According to the present invention, the set-by-cell function that can be set by the channel selection key with the on / off parameter set for each channel as the operation target can be assigned to the user-defined key, and the set-by-cell function is assigned. When a user-defined key is operated, a selection screen for selecting a parameter to be operated is displayed on the display means, and the parameter selected on the selection screen can be set as an operation target with a channel selection key. Even for the set-by-cell function assigned to one user-defined key, a plurality of parameters can be selected as an operation target. As a result, the user-defined key can be used effectively, but the improvement in the speed of operation (operability), which is a feature of the set-by-cell function, is essentially the same as in the past. In addition, since the selection screen for selecting the parameter to be operated is displayed, the parameter to be set as the operation target of the set-by-cell function can be set while checking, and the occurrence of an erroneous operation can be prevented. .

  Next, the user-defined key section 5 provided on the console panel 2 is shown in an enlarged manner in FIG. The user-defined key section 5 is provided with, for example, twelve user-defined keys 5a, 5b,. User-defined keys 5a to 5m are keys for executing pre-programmed functions such as scene switching, talkback, on / off of built-in oscillator, and the like. ) Functions that can be assigned to 5a to 5m can be assigned. A part of the list of functions that can be assigned is shown in FIG. In FIG. 6, the functions in the function column can be assigned. User defined keys 5a to 5m include a set by cell (SET BY SEL) function, a scene (SCENE) switching function, and a talk. Functions such as a back function and an oscillator function can be assigned. In addition, a “NO ASSIGN” function is provided to clear the functions assigned to the user defined keys 5a to 5m. When there are some parameters in the function to be assigned, the parameters are indicated in the parameter 1 (PARAMETER 1) column. Further, when there is a parameter below the parameter shown in the parameter 1 (PARAMETER 1) column, the parameter is shown in the parameter 2 (PARAMETER 2) column.

  One parameter in the parameter 1 (PARAMETER 1) column or parameter 2 (PARAMETER 2) column can be selected as an operation target. The SET BY SEL function is a function for quickly setting ON / OFF parameters to be set for each channel, and the channel strip assigned to the ON / OFF setting of the parameter to be operated is assigned to that channel. It can be set by operating a cell (SEL) key 31a provided in the. The parameter to be operated in the SET BY SEL function is to turn on the power supplied to the head amplifier assigned to each channel of the input channel system as shown in the PARAMETER 1 column in FIG. / Parameter to be turned off “SET [+ 48V]”, parameter “SET [φ]” to switch the normal phase and reverse phase of the head amplifier, and the position of the signal sent from the input channel to the MIX buses 45a to 45m, post fader Parameter “SET [PRE SEND]” to be switched between (POST SEND) and pre-fader (PRE SEND), parameter “SET [TO STEREO]” to turn on / off the signal sent from the input channel to the stereo bus 46, input channel Can be selected from the parameters “SET [TO MONO]” for turning on / off the signal sent from to the mono bus 47.

  In this case, in the list shown in FIG. 6, the parameter “−” does not define a parameter and is left blank, but the top level of the parameter 1 (PARAMETER 1) column in the SET BY SEL function The blank of has a special meaning. When this blank is selected, the SET BY SEL function with menu that allows you to select the parameter to be operated from all the parameters in the SET BY SEL function will be assigned. This is a characteristic configuration in the invention. That is, if a blank “-” is assigned as parameter 1 to any of the user-defined keys 5a to 5m, a set with a menu is set when the assigned user-defined keys 5a to 5m are pressed. The program of the bi-cell (SET BY SEL) function is activated, and a menu screen for selecting a parameter to be operated by the set-by-cell (SET BY SEL) function is displayed on the LCD display 6. An example of this menu screen is shown in FIG. As shown in FIG. 8, the LCD display 6 displays buttons for all the parameters [+ 48V], [φ], [PRE SEND], [TO STEREO], and [TO MONO], which are to be operated. When the cursor is placed on the parameter button and the enter key 7d is pressed, the parameter is set as an operation target of the SET BY SEL function. Note that the LCD display 6 may have a touch panel function and may be set as an operation target by touching a parameter to be operated.

As a result, it is not necessary to previously assign the parameters to be operated to the user defined keys 5a to 5m, so the user defined keys 5a to 5m having a limited number are efficiently used. Will be able to be used. In addition, since the parameter to be operated by the SET BY SEL function is selected from the displayed menu, it can be operated while checking the parameter to be operated by the SET BY SEL function. It becomes possible to prevent the occurrence of erroneous operations.
For example, if the SET BY SEL function with a menu is assigned to the user defined keys 5a, when the user defined keys 5a is pressed, the SET BY SEL with a menu is set. ) The function is activated. Then, when the parameter [TO STEREO] for sending the signal of the channel to the stereo bus as an operation target is selected from the menu displayed on the LCD display 6, the stereo bus is held while the user defined keys 5a are kept pressed. When the cell (SEL) key 31 of the channel strip assigned to the input channel to be sent to 46 is pressed, the signal of that input channel is sent to the stereo bus. By pressing the channel strip cell (SEL) key 31 assigned to the input channel you want to send to the stereo bus while holding down the user-defined keys 5a, you can set the parameter [TO STEREO ] Can be quickly set on / off.

Note that when the program of the SET BY SEL function is executed, for the channel for which the parameter to be operated is turned on by the previous operation, the cell in the channel strip assigned to that channel ( The LED 31a of the (SEL) key 31 is turned on. For this reason, ON / OFF setting can be performed while confirming the lighting state of the LED 31a. Each time the cell (SEL) key 31 is pressed, a toggle operation is performed to reverse the on / off state.
In addition, as shown in the parameter 1 (PARAMETER 1) column of FIG. 6, the parameter to be operated in the scene (SCENE) switching function is a parameter “INC RECALL” for increasing the recall number to be recalled from the scene memory, The parameter “DEC RECALL” is used to decrease the recall number to be recalled, and the parameter “DIRECT RECALL” is used to directly specify the recall number to be recalled from the scene memory. In this case, since the parameter number “DIRECT RECALL” requires a scene number to be directly designated, the parameters of this scene number “SCENE # 000 to # 300” are shown in the parameter 2 (PARAMETER 2) column.

Next, FIG. 7 shows a setting screen displayed on the LCD display 6 when a function is assigned to user defined keys 5a to 5m.
The setting screen shown in FIG. 7 is a setting screen for assigning a function to USER DEFINED KEY 1 which is a user defined key 5a. On the setting screen, the assignable functions are displayed in the FUNCTION field. When one of the displayed functions is selected, the selected function character is displayed in white and selected in the PARAMETER 1 field. Displays the parameters to be operated in the function. By moving the cursor to “▲” and “▼” in the PARAMETER 1 field and pressing the enter key 7d, the parameters hidden above and below can be displayed up or down. When one is selected as a setting target, the character of the parameter set as the setting target is displayed in white. After selecting, move the cursor to the “OK” key and press the enter key 7d to assign the selected function to USER DEFINED KEY 1 and confirm the selected parameter as the operation target. close. If the “CANCEL” key is pressed, the setting contents are canceled and the setting screen is closed. In this way, functions can be assigned to USER DEFINED KEYs 1 to 12, which are user defined keys 5a to 5m, respectively. FIG. 7 shows a screen in which the set by cell (SET BY SEL) function in which the parameter “SET [+ 48V]” is selected is assigned to USER DEFINED KEY 1.

  FIG. 9 shows another embodiment of the functions that can be assigned to user defined keys 5a to 5m. FIG. 9 shows a part of a list of functions that can be assigned. In this embodiment, the parameters of the set by cell (SET BY SEL) function are changed. In the set by cell (SET BY SEL) function that can be assigned to the user defined keys 5a to 5m shown in FIG. 9, the parameter “SET [+ 48V]”, parameter “SET [φ]”, parameter “SET In addition to [PRE SEND], parameter “SET [TO STEREO]”, parameter “SET [TO MONO]” and “− (blank)” to assign the SET BY SEL function with menu, a different menu Parameter “MENU1” and parameter “MENU2” are assigned to assign the SET BY SEL function with the menu. Here, for example, the parameter “MENU1” in the SET BY SEL function is assigned to any of the user defined keys 5a to 5m, and the assigned user defined keys 5a to 5m are assigned. If pressed, the menu 1 set-by-cell (SET BY SEL) function is activated. As a result, the menu screen of menu 1 shown in FIG. 10 for selecting a parameter to be operated by the set-by-cell function is displayed on the LCD display 6. In menu 1 shown in FIG. 10, three buttons of parameters [+ 48V], [φ], and [PRE SEND] are displayed. By placing the cursor on the parameter button to be operated and pressing the enter key 7d. The parameter is set as the operation target of the SET BY SEL function.

If the parameter “MENU2” is assigned to any of the user-defined keys 5a-5m and the assigned user-defined keys 5a-5m are pressed, the menu 2 set with menu The bi-cell (SET BY SEL) function is activated. As a result, the menu screen of menu 2 shown in FIG. 11 for selecting a parameter to be operated by the set-by-cell function is displayed on the LCD display 6. In menu 2 shown in Fig. 11, four buttons of parameters [+ 48V], [PRE SEND], [TO STEREO], and [TO MONO] are displayed. Place the cursor on the button of the parameter to be operated and enter. By pressing the key 7d, the parameter is set as the operation target of the set by cell (SET BY SEL) function.
Even if such a parameter “MENU1” or parameter “MENU2” is provided, a plurality of operation target parameters can be operated with one user-defined key, so that the number of users is limited. The user defined keys 5a to 5m can be used efficiently. In addition, since the operation target of the set by cell (SET BY SEL) function is selected from the displayed menu, it becomes possible to operate while confirming the parameters to be operated by the set by cell (SET BY SEL) function. Occurrence can be prevented.

Next, a flowchart of a function assignment process that is started when an instruction for assigning a function to one of user defined keys 5a to 5m is received by moving to a setting screen for assigning a function or the like. As shown in FIG.
When the function assignment process shown in FIG. 12 is started, a list of user defined keys 5a to 5m is displayed on the LCD display 6 in step S10, and user defined keys 5a to 5m are displayed in step S11. Wait until any 5m key is selected. Here, if it is detected that any one of the user defined keys 5a to 5m is selected, it can be assigned to the user defined keys 5a to 5m in step S12. A list of various functions is displayed on the LCD display 6. This list is the list shown in FIG. 6 or FIG. Next, the process waits until any function is selected in step S13. Here, when it is detected that any one of the functions is selected, a process of assigning the selected function to any one of the selected user defined keys 5a to 5m is performed, and the function assignment is performed. The process ends.

Next, FIG. 13 shows a flowchart of a function program process that is started when it is detected that any one of user defined keys 5a to 5m is pressed and turned on.
When the function program process is started, the function assigned to the user defined keys turned on in step S20 is determined, and the determined function is a set by cell (SET BY SEL) function with a menu. Whether or not it has been determined is determined in step S21. If it is determined that the determined assigned function is not a set-by-cell function with a menu, the program of the assigned function determined by branching to step S22 is executed. The program of the function that is activated and executed, and assigned to the user defined keys after execution is terminated, and the function program processing is terminated.
If the assigned function determined in step S21 is determined to be a set-by-cell (SET BY SEL) function with a menu, the process proceeds to step S23 and the program for the set-by-cell (SET BY SEL) function is activated. Then, a selection screen for selecting the parameter of the SET BY SEL function with menu is displayed on the LCD display 6. This selection screen is the menu screen shown in FIG. 8, FIG. 10, or FIG. 11 according to the assigned set-by-cell function with a menu (SET BY SEL) function.

  Then, it waits in step S24 until any parameter displayed on the displayed selection screen is selected, and when it is detected that a parameter has been selected by clicking on any parameter button or the like. The process proceeds to step S25. In step S25, the next program as a subroutine for operating the selected parameter as an operation target is started. Next, the selection screen displayed on the LCD display 6 in step S26 is deleted. And it waits until the user defined key (user defined keys) turned on in step S27 is turned off. In this case, it is detected that user-defined keys are turned off. The user-defined key (user defined key) that the user has kept pressing after processing of the assigned SET BY SEL function is completed. when the hand (finger) is released from the keys. If it is detected that the user defined keys are turned off, the process proceeds to step S28 and the program of the set by cell (SET BY SEL) function assigned to the turned off user defined keys is set. The function program process ends.

Next, FIG. 14 shows a flowchart of another function program process that is started when it is detected that any one of user defined keys 5a to 5m is pressed and turned on.
When the other function program processing shown in FIG. 14 is started, the function assigned to the user defined keys turned on in step S20 ′ is determined, and the determined function is a set-by-cell with a menu. Whether or not the (SET BY SEL) function is selected is determined in step S21 ′. Here, if it is determined that the determined assigned function is not a set-by-cell function with a menu, the program of the assigned function determined by branching to step S22 ′. Is activated and executed, and after execution, the function program assigned to the user defined keys is terminated, and the function program processing is terminated.
If the assigned function determined in step S21 ′ is determined to be a set-by-cell function with a menu, the program proceeds to step S23 ′ and the program for the set-by-cell function is started. Then, a selection screen for selecting a parameter of the set-by-cell function with a menu is displayed on the LCD display 6. This selection screen is the menu screen shown in FIG. 8, FIG. 10, or FIG. 11 according to the assigned set-by-cell function with a menu (SET BY SEL) function.

When the process of step S23 ′ is completed, it is determined in step S24 ′ whether any parameter displayed on the displayed selection screen has been selected. If it is detected that any parameter button is clicked or the like and the parameter is selected, the process proceeds to step S25 ′. In step S25 ′, the next program as a subroutine for operating the selected parameter as an operation target is started. Next, it is determined whether or not the user-defined keys that were turned on in step S26 ′ are turned off. If it is determined that the user-defined keys that were turned on are turned off, In step S27 ′, the selection screen displayed on the LCD display 6 is deleted. In this case, it is detected that user-defined keys are turned off. The user-defined key (user defined key) that the user has kept pressing after processing of the assigned SET BY SEL function is completed. when the hand (finger) is released from the keys. If it is not determined that the user-defined keys that were turned on in step S26 ′ have been turned off even after a predetermined time has elapsed, the process returns to step S24 ′ and steps S24 ′ to S26 ′ are performed. Processing is performed again. If it is not detected in step S24 ′ that a parameter has been selected even after a predetermined time has elapsed, the process jumps to step S26 ′ and the above processing is performed. When the process of step S27 ′ is completed, the process proceeds to step S28 ′, the program of the SET BY SEL function assigned to the user-defined keys turned off is terminated, and the function program process is terminated. To do.
In the other function program processing shown in FIG. 14, the selection screen displayed in step S23 ′ continues to be displayed until the user defined keys are turned off, during which the parameter is selected. You can change it anytime.

Next, FIG. 15 shows a flowchart of the set by cell (SET BY SEL) process that is activated when the set by cell (SET BY SEL) function is activated.
When the set by cell (SET BY SEL) process is activated, it is set in step S30 that the set by cell (SET BY SEL) function is being executed. In this setting, the setting state set by the function program process is read and stored in the buffer. At this time, a screen representing the assigned parameter to be operated is displayed on the LCD display 6. Next, the parameter to be operated is set in step S31. The parameter to be operated is a parameter determined in step S25 in the function program process and stored in the buffer. In step S32, the on / off state of the parameter is checked for each channel assigned to the channel strip that can handle the parameter to be operated.

  In step S33, the LED 31a built in the cell (SEL) key 31 of the channel strip assigned to the channel for which the parameter to be operated is turned on is turned on. The LED 31a built in the cell (SEL) key 31 of the channel strip assigned to the channel is turned off. As a result, it is possible to confirm at a glance for each channel that can handle the on / off setting state of the parameter to be operated. In step S34, the process waits until an instruction to stop the set-by-cell function is given. This stop instruction is instructed in step S28 (step S28 ') in the function program processing. When the stop instruction is detected, it is set in step S35 that the set by cell (SET BY SEL) function is stopped. . In this setting, the contents of the buffer are cleared, and when the process of step S35 is finished, the set by cell (SET BY SEL) process is finished.

Next, FIG. 16 shows a flowchart of the cell (SEL) key process activated when it is detected that the cell (SEL) key 31 in any channel strip is operated.
When the cell (SEL) key processing is activated, it is checked in step S40 whether the set by cell (SET BY SEL) function is being executed, and whether or not the checked set by cell (SET BY SEL) function is being executed. Is determined in step S41. Here, when it is determined that the SET BY SEL function is not executed by looking at the above buffer, the cell (SEL) key that is the starting source is selected as the channel to be operated by branching to step S42. The channel to which 31 channel strips are assigned is set as the channel to be operated, and the normal cell (SEL) key 31 processing is executed, and the cell (SEL) key processing is terminated.

  On the other hand, if it is determined in step S41 that the set by cell (SET BY SEL) function is being executed, the process proceeds to step S43, and the cell (SEL) key 31 is operated. Switch to reverse. The channel to be switched is a channel to which the channel strip of the cell (SEL) key 31 that is the starting source is assigned. Next, in step S44, it is determined whether or not the parameter to be operated is switched on. If it is determined that the parameter is switched on, the process proceeds to step S45. In step S45, the parameter to be operated is set to ON, and the LED 31a built in the operated cell (SEL) key 31 is turned on in step S46. If it is determined in step S44 that the switch has been turned off, the process branches to step S47, and the parameter to be operated is set to off. Next, the LED 31a built in the operated cell (SEL) key 31 is turned off in step S48. When the process of step S46 or step S48 is completed, the cell (SEL) key process is terminated. Note that processing for on / off of the parameter to be operated is executed by the signal processing unit 19.
