The algorithm is realized by a program set in the signal processing unit 8, and the program is loaded from the flash memory 20 or the like into the signal processing unit 8 under the control of the CPU 18. In FIG. 2, reference numeral 51 denotes an analog input unit. When an analog audio signal of a microphone level or a line level is received, it is converted into a digital audio signal and supplied to the signal processing unit 8. A digital input unit 52 receives a digital audio signal and converts it into a format inside the signal processing unit 8. Reference numeral 66 denotes an analog output unit that converts the digital audio signal supplied from the signal processing unit 8 into an analog audio signal and outputs the analog audio signal to the outside. A digital output unit 68 converts the digital audio signal in the internal format supplied from the signal processing unit 8 into a digital audio signal in a predetermined format (AES / EBU, ADAT, TASCAM, etc.) and outputs it.

  The configuration described above is realized by the waveform I / O unit 10, which is hardware separate from the signal processing unit 8, and various cards inserted therein, but the configuration other than the above is performed in the signal processing unit 8. It is realized by a program that runs. Reference numeral 55 denotes an input channel adjustment unit, which adjusts the volume and sound quality of the “48” input channels based on the operation of operation elements such as electric faders and knobs on the operation panel 30. An input patch unit 54 assigns digital audio signals supplied from a plurality of input ports such as the input units 51 and 52 to arbitrary input channels in the input channel adjustment unit 55.

  Reference numeral 58 denotes a MIX bus group composed of “16” MIX buses. In each MIX bus, the digital audio signal of each input channel supplied to the MIX bus is mixed.

These general-purpose equalizers can be inserted into any channel of the input channel adjustment unit 55 or the MIX output channel unit 62. .

  Here, the parameters adjusted in the input channel adjustment unit 55 and the MIX output channel unit 62 will be described in further detail. In the input channel adjustment unit 55, an equalizer is provided for each of the “48” input channels, and thereby the frequency characteristics of each input channel audio signal are adjusted. Further, a dynamics adjustment unit is provided at the subsequent stage of each equalizer, and thereby, compressor processing, gate processing, and the like are performed on the audio signal of each channel. A volume adjustment unit is provided following the dynamics adjustment unit. Here, the signal level (gain) of the audio signal of each channel is adjusted according to the operation amount of the corresponding electric fader.

  The audio signal whose signal level has been adjusted is further adjusted in send level (gain) in a “16” send level adjustment unit provided corresponding to the “16” MIX bus. The “48” × “16” audio signals whose send levels are adjusted are set to “16” as necessary via a send on / off switching unit that switches whether or not the audio signals are actually supplied to the MIX bus. To the MIX bus of the system. Also in the MIX output channel section 62, the above-described equalizer, dynamics adjustment section, and volume adjustment section are provided for each of the “16” MIX output channels, and adjustments are made via these.

1.3. Data Configuration Next, the data configuration in the present embodiment will be described with reference to FIG. FIG. 3 shows various data stored in the RAM 22 and the flash memory 20.
Reference numeral 100 denotes current data, which is composed of various parameters related to the mixing processing in the signal processing unit 10 as described above. 108 is a time code register, 110 is an event timer register, and 112 is an action timer register, both of which store the elapsed time since the reset. The elapsed times stored in the registers 108, 110, and 112 are all automatically updated every 10 msec, but the timing at which these registers are reset can be made independent. More specifically, the time code register 108 measures the elapsed time after the reproduction of the data list is started (“time code” in the data list processing is the elapsed time in the digital mixer. In this case, the event timer register 110 is displayed after each event data is executed. The elapsed time is measured, and the action timer register 112 measures the elapsed time after each action data is executed.

  The current data 100 and the registers 108, 110, and 112 are all provided in an area in the RAM 22, but other data is stored in the flash memory 20 so that it is not lost even when the power is turned off. These are loaded into the RAM 22 as necessary. First, reference numeral 102 denotes a scene data group, which is composed of a plurality of scene data SCN-1 to SCN-m. One scene data is a parameter of the input channel adjustment unit 55, general-purpose equalizer group 56, and MIX output channel unit 62 in the current data at a certain point in time (controls the signal processing unit 8 in the parameter group in the current data). Parameter group, at least the parameter group recorded in the library data 104 described later is not included). When the user performs a predetermined scene store operation on the touch panel 2, the setting value in the current data at the time of the operation related to these parameters is designated as one specified scene data SCN-k (1 ≦ k ≦ m). When the user designates scene data on the touch panel 2 and performs a predetermined scene recall operation, the current data 100 in the RAM 22 is updated to match the scene data, and the updated current data 100 is updated. The state of the signal processing unit 8, the touch panel 2, and the display / operation element group 4 is updated so that the electric fader group 6 is driven so as to match the above.

  Next, reference numeral 104 denotes a library data group, which includes a plurality of library data LIB-1 to LIB-n. One library data is an allocation state in the input patch unit 54 and the output patch unit 64 in the current data at a certain time (a parameter group that controls the signal processing unit 8 among the parameter groups in the current data, and includes at least (The parameter group recorded in the library data 104 to be described later is not included). When the user performs a predetermined library store operation on the touch panel 2, the setting value in the current data at the time of the operation related to these allocation states is stored in the flash memory 20 as the specified library data LIB--k (1 ≦ k ≦ n). When the user designates library data on the touch panel 2 and performs a predetermined library recall operation, the current data 100 in the RAM 22 is updated so as to match the library data, and the updated current data 100 is updated. The allocation states of the input patch unit 54 and the output patch unit 64 are updated so as to match. The scene data can be linked to the library data. When the scene data linked to the library data is recalled, the linked library data is automatically recalled.

  The above-described data groups 102 and 104 can be recalled by a user's manual operation, but these recalls can be automatically executed in a predetermined order. The data lists 120A to 120N define the execution order and execution timing. Each of the data lists 120 </ b> A to 120 </ b> N is a record in which a plurality of “command data” each specifying “command” is arranged in the order of execution, and finally end data 130 indicating the end of the command data is arranged. is there. Here, “commands” are classified into two types, “events” and “actions”, and the command data corresponding to each is called “event data” and “action data”. In other words, the command (command data) is a high-level data name that includes both the event (event data) and the action (action data). It is assumed that it is handled as data. In the example of the data list 120 </ b> A, 121, 123, and 125 with the letter “E” are event data, and 122-1 to p, 124-1 to q, 126 with the letter “A”. −1 to r are action data. Thus, the data list has a structure in which event data and action data are arranged in order of execution (structure in which command data is arranged in the order of reading in one file). A command register 106 is used when executing or editing the data list. During execution of the data list, the command register 106 indicates command data currently being executed or one command data executed last. During editing of the data list, command data to be edited is designated. The command data instructed by the command register 106 is referred to as “current command data”. Only one command is always set as the current command, and a plurality of commands cannot be the current command at the same time.

Next, details of event data and action data will be described. First, each event data includes a “trigger part” and a “title part”. Here, the title portion designates an arbitrary character string as the name of the event data. An event represents a group of actions, for example, a group of songs or a group of curtains (or a break of the group), so that “Song A”, “Song B”, A name such as “act 1” or “act 2” may be given. Further, the trigger unit specifies the timing at which the event is to be executed, and the trigger unit is classified into the following three types according to the mode of specifying the timing. The three types are also event data classifications.
(1) Manual type: This trigger unit uses a timing at which a user performs a predetermined event execution operation as an execution timing.
(2) Relative time type: This trigger unit is based on the elapsed time (the time counted by the event timer register 110) from the execution timing of the latest event data whose execution order is ahead of the event data. It defines the execution timing.
(3) Absolute time type: This trigger section defines the execution timing by the value of the time code used as a reference.
Note that “execute an event” specifically means “change the display content of the touch panel 2”, that is, perform processing for allowing the user to recognize a break of a group of actions. Unlike the action data, it does not affect the parameter value in the current data 100, nor does it involve an operation for outputting a signal to an external device.

  In the present embodiment, one event data and several action data (typically a plurality of action data, but may be one action data) are collected as a group. The several action data included in the group is called “subordinate” to the one event data included in the group, and the several action data subordinate to the one event data is one Called “Action Data Group”. This group is typically equivalent to one song or one act during the performance. In the data list of the embodiment, one event data and an action data group arranged after the one event data (the actions arranged between the one event data and the next event data) A group of data). In the example of the data list 120 </ b> A, the action data 122-1 to 122-p constitute one action data group and are subordinate to the event data 121. Similarly, the action data 124-1 to q constitute another action data group and are subordinate to the event data 123. Similarly, the action data 126-1 to r constitute another action data group and are subordinate to the event data 125.

Next, each action data includes a “trigger part”, a “title part”, and an “action part”. Here, the title portion designates an arbitrary character string as the name of the action data. The action executes parameter control in the digital mixer such as scene recall, MIDI data output and GPI data output during the performance, so that they can be easily recognized, "Scene 1 Recall", "Scene 2 Recall" , “MIDI1 output” or “GPI1 output” may be used. In addition, the trigger unit designates a timing at which the action is to be executed, and the trigger unit is classified into the following three types according to an aspect of designating the timing. The three types are also action data classifications.
(1) Manual type: This trigger unit uses the timing at which the user performs a predetermined event execution operation as the execution timing, as in the case of event data.
(2) Event-based relative time type: This trigger unit determines the elapsed time after execution of the dependent event data (in other words, the execution timing of the latest event data whose execution order is earlier than the action data) This is an elapsed time from the time, and this defines the execution timing by the time counted by the event timer register 110).
(3) Command Reference Relative Time Type: This trigger section is an elapsed time after execution of command data (regardless of event / action) of the immediately preceding execution order (this is counted by the action timer register 112). Execution timing).

  In this case, when the action data of the first execution order in one action data group is “command reference relative time type”, its execution timing is defined based on the execution timing of the dependent event data. Regardless of whether the reference is “event” or “command”, the setting value indicating the execution timing is exactly the same. In addition, for action data having an execution order other than the head, the setting value representing the execution timing is naturally different depending on whether the reference is “event” or “command”. Unlike the event data, there is no “absolute time type” in action data.

The “action part” of each action data designates the content of the action to be executed. Specifically, (1) any one of the scene data SCN-1 to SCN-m is recalled (2) any The library data LIB-1 to LIB-n are recalled (3) MIDI data output (4) GPI data output. When scene recall or library recall is performed in the action part, the scene data or library data number (SCN-1 to SCN-m or LIB-1 to LIB-n) to be recalled is designated in the action part. Is done. Further, when outputting MIDI data or GPI data, the substance of the MIDI data or GPI data is described in the action section, and when the action data is executed, the described MIDI data or GPI data is the other The data is output to an external device via the I / O unit 16. The GPI data is data for remotely controlling a video editing device or the like.

2． Operation of the embodiment
2.1. Display of List Display / Control Screen When the user performs a predetermined operation on the touch panel 2, the list display / control screen shown in FIG. 4 is displayed on the touch panel 2.
In FIG. 4, reference numeral 230 denotes a data list selection unit. By operating this, a user can select one data list 120 </ b> A to 120 </ b> N to be edited. Next, an event list display unit 200 displays the contents of a list (event list) obtained by extracting only event data from the selected data list. Needless to say, not all event data in the data list is displayed simultaneously on one screen, but all event data may be displayed using a so-called scroll function or the like. The event list display unit 200 includes a plurality of “rows” (event columns) corresponding to each event data, and each event column is arranged from the top to the bottom according to the execution order. Each event field is divided into an event number display unit 202, a trigger display unit 204, and an event content display unit 206 in the horizontal direction.

  In the event number display unit 202, numbers “000”, “001”,... Are displayed in ascending order according to the execution order of each event data. In the trigger display part 204, the contents of the trigger part of the event data are displayed. First, the ones with “2 digits x 4” displayed like “00: 00: 00: 00” are absolute time type, and “↑ After” like “↑ After 120 sec” What is displayed after the character is a relative time type, and what is displayed as “[MANUAL]” is a manual type. In the event content display unit 206, the name specified in the title part of the event data is displayed.

  Next, an action list display unit 220 displays the contents of a list (action list) obtained by extracting only action data subordinate to the “current event”. That is, a list in which all action data subordinate to the currently selected event (current event) in the selected data list is arranged in the execution order is displayed. Therefore, the content of the action list is updated every time the current event is changed. The action list display unit 220 is composed of a plurality of “rows” (action fields) corresponding to each action data, and each action field is arranged from top to bottom in order of execution order according to execution order. Has been. Each action column is divided into an action number display unit 222, a trigger display unit 224, and an action content display unit 226 in the horizontal direction. In the action number display section 222, numbers “000”, “001”,... Are displayed in ascending order according to the execution order of each action. In the trigger display part 224, the content of the trigger part of the action data is displayed as the execution timing of the action data. First, what is displayed after the character “↑ After”, such as “↑ After 0.5 sec”, is “command reference relative time type”, and “Event After 30.0 sec”, “Event What is displayed after the word “After” is “event reference relative time type”, and what is displayed “[MANUAL]” is manual type. In the action content display part 226, the name specified in the title part of the action data is displayed.

  Reference numeral 210 denotes a line cursor, which is simultaneously arranged in one event column in the event list display unit 200 and one action column in the action list display unit 220, and emphasizes those columns more than other columns. indicate. In FIG. 4, this highlighting is shown by hatching. The event in the event column in which the row cursor 210 is arranged is called “current event”, the action in the action column is called “current action”, and the column to which the current event and the current action belong is called “cursor column”. A list cursor 212 is displayed so as to surround either the event list display unit 200 or the action list display unit 220. The list cursor 212 is displayed on the event list display unit 200 side when the current command (command instructed by the command register 106) is an event, and the action list display unit 220 when the current command is an action. Displayed on the side. The intersection position of the list cursor 212 and the line cursor 210 is called a “cursor position”, and the current command is a command (either an event or an action) at this cursor position.

  Note that the current event is always only one event (a plurality of events cannot be the current event at the same time). Similarly, there is always only one action as the current action (a plurality of actions cannot be the current action at the same time). Of the current event and current action, only one of the most recently edited objects is set as the current command (both current event and current action are not simultaneously set as the current command). Further, the position of the line cursor 210 itself is fixed at the position shown in the list display / control screen. Accordingly, when the current event is changed, the display contents of all the lines of the event list display unit 200 are collectively displayed so that an event corresponding to the new current event is displayed at the position of the line cursor 210. Scroll up or down (with the display order of the events being held fixed). Similarly, when the current action is changed, the display contents of all lines in the action list display unit 220 are collectively displayed (display) so that an action corresponding to the new current action is displayed at the position of the line cursor 210. Scroll up or down (with the displayed order of actions being fixed).

  Reference numeral 252 denotes an up scroll button for instructing to return the cursor position to the command having the previous execution order with respect to the current command, and to set the command at the cursor position as a new current command. Reference numeral 256 denotes a down scroll button for instructing to advance the cursor position to a command whose execution order is one after the current command and to set the command at the cursor position as a new current command. Reference numeral 254 denotes an EDIT button for instructing editing of the current command. That is, when the EDIT button 254 is pressed, a pop-up window for editing the contents of the current command is displayed (not shown), and the user can select a trigger part, a title part, and (in the case of action data) in the pop-up window. The contents of the action part can be arbitrarily edited. However, in the pop-up window, when scene recall is specified as the content of the action part, the specified scene data is limited to scene data that already exists in the scene data group 102. Reference numeral 258 denotes an action / store button for instructing that the current contents of the current data 100 be stored in the flash memory 20 as scene data to be recalled in the current command.

2.2. Processing corresponding to pressing of the action / store button 258 Next, the contents of processing executed when the action / store button 258 is pressed will be described with reference to FIG.
When the process proceeds to step SP2 in FIG. 6, the contents of the current command are read from the currently selected data list, and it is confirmed whether or not the current command indicates a scene recall. Next, when the process proceeds to step SP4, the process branches according to the confirmation result of step SP2. First, if the current command does not indicate a scene recall, it is determined “NO” here, and the processing of this routine is immediately terminated. More specifically, if the current command is action data instructing library recall, MIDI data output or GPI data output, or event data, the processing of this routine is immediately terminated. On the other hand, if the current command is action data for instructing scene recall, “YES” is determined, and the process proceeds to step SP6.

  Here, when the contents of the current data 100 are stored in the flash memory 20 as scene data to be recalled by the current command, the contents of the current data 100 are overwritten on the scene data originally specified in the current command (overwrite mode). ) And the scene data originally designated may be left as they are, and a new scene data may be created (another scene mode). Both are collectively referred to as “store mode”. In step SP6, it is confirmed whether this store mode is an overwrite mode or another scene mode. Specifically, in this embodiment, as shown in FIG. 5, a pop-up window 270 is displayed on the touch panel 2 and the background list display / control screen is darked out (in the figure, darkout is represented by a broken line). ).

  In the pop-up window 270, reference numeral 272 denotes an overwrite button. When pressed, the overwrite mode is designated as the store mode. Reference numeral 274 denotes a different scene button which, when pressed, designates another scene mode as the store mode. Reference numeral 276 denotes a caution section. When there is other action data that designates the same scene data as the scene data specified by the current action (that is, the current command) as a recall target, a caution notice to that effect exists. Is displayed. This is because in such a case, if the contents of the current data 100 are saved in the overwrite mode, the operation of the other action data is affected. If there is no other action data that designates the same scene data as the scene data designated by the current action (that is, the current command) as a recall target, nothing is displayed in the notice section 276.

  When one of the overwrite button 272 and another scene button 274 is pressed by the user, the pop-up window 270 is closed and the list display / control screen (FIG. 4) is displayed again on the touch panel 2 in the normal state. In FIG. 6, the process proceeds to step SP <b> 8, and the process branches depending on whether or not the designated store mode is “another scene mode”. That is, if another scene mode is designated, “YES” is determined, and the process proceeds to step SP10. Here, new scene data is additionally created in the scene data group 102 in the flash memory 20 (scene data having a new number (new scene number) is additionally created), and the current scene is included in the new scene data. The setting values of various parameters recorded in the current data 100 are written. Next, when the process proceeds to step SP12, the scene data currently specified in the current action (that is, the current command) is changed to newly created scene data. In other words, in the currently selected data list, the content of the action part related to the current command is the number of the newly created scene data from the number of the originally specified scene data (the currently specified scene data). Can be rewritten. Further, in the action list display unit 220 on the touch panel 2, the action content display unit 226 at the cursor position is changed to the content corresponding to the newly created scene data. When the above steps are finished, the processing of this routine is finished.

  On the other hand, if the designated store mode is the “overwrite mode”, “NO” is determined in step SP8, and the process proceeds to step SP14. Here, the scene data currently specified in the current action (that is, the current command) is specified as the scene data to be processed. Next, when the process proceeds to step SP16, the contents of the scene data to be processed are overwritten with the contents of the current current data 100. In other words, the content of the action part related to the current command in the currently selected data list (scene data number for specifying scene data) is maintained without being rewritten and specified as the content of the action part related to the current command. For the scene data corresponding to the number of the scene data being recorded, the setting values of various parameters recorded in the corresponding scene data are rewritten to the setting values recorded in the current current data 100. When the above steps are finished, the processing of this routine is finished. As described above, in the overwrite mode, the content of the scene data currently specified in the current action is updated, but the content of the currently selected data list itself is not changed at all, and the event list display unit 200 and the action are not changed. The display content of the list display unit 220 is not changed.

  As described above, according to the present embodiment, when the user moves the cursor to a desired action data location in the action list display unit 220 and presses the action / store button 258, the content of the current current data 100 is changed. It is stored in the scene data group 102 as the contents of the scene data to be recalled in the action data. Thereby, the contents of the scene data corresponding to the specified action data can be quickly specified, and the data list editing work and the scene data editing work can be efficiently advanced.

3． Modifications The present invention is not limited to the above-described embodiments, and various modifications can be made as follows, for example.
(1) In the above embodiment, the event data and the action data are processed by various programs executed by the CPU 18, but only these programs are stored in a recording medium such as a CD-ROM or a memory card. Then, it can also be distributed through a transmission line.

(2) In the above embodiment, the data list records event data and action data in one file in the order of execution. However, the data structure is not limited to that in the above embodiment. For example, even when the command (command data) corresponding to the event data in the above embodiment does not exist and the data list is configured only by the command (command data) corresponding to the action data (for example, Patent Document 1), The present invention can be applied.

(3) In step SP6 of the above embodiment, the pop-up window 270 (FIG. 5) is displayed to determine whether the store mode is the overwrite mode or the different scene mode. The determination method is not limited to that of the embodiment. For example, the user designates either the overwrite mode or another scene mode in advance as the store mode to be applied, and this pre-designated store mode is applied immediately when the action / store button 258 is pressed. May be.

(4) As another modification of the method for determining the store mode in step SP6, the store mode may be confirmed according to the operation of the action / store button 258. For example, when the user presses only the action / store button 258, another scene mode is selected, and when the user presses the action / store button 258 while pressing another switch (such as a shift switch not shown), the overwrite mode is selected. You may make it select.

(5) As another modification of the store mode determination method in step SP6, the user does not intentionally specify the store mode but automatically determines the store mode based on the data list. Also good. For example, it is determined whether the scene data specified as the recall target in the current command (that is, the current action) is also specified as the recall target in the other action data in the currently selected data list. If the result is affirmative (if the scene data is also specified in other action data), another scene mode is selected as the store mode, and if this determination result is negative (the scene data is current When specified only in the command), the overwrite mode may be selected as the store mode.

(6) In the above embodiment, the cursor position is displayed by the line cursor 210 and the list cursor 212. However, the display of the cursor position is not limited to that in this embodiment. For example, “cursor” may be indicated by highlighting, and this cursor may appear only in the display column (one of the event column or the action column) related to the current command.

(7) In the above embodiment, the present invention is applied to a digital mixer. However, the present invention is not limited to a digital mixer, and an analog mixer and other various acoustic signal processing devices that perform automatic control according to a data list.
