[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a digital mixer that performs intensive control of audio equipment in a venue for performing concerts and plays.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a mixer device for controlling audio equipment in a venue such as a concert or a theater is known. In such venue audio equipment, a large number of microphones and a large number of speakers are used, and sound effects are used in a wide variety. The mixer device centrally controls how many inputs are mixed, how effects are applied, and which output system is output. For this reason, some conventional mixer apparatuses can store a mixing state and a connection state for each scene as a scene (SCENE). By storing the set state as one scene and recalling the recalled scene later, the set state can be easily reproduced.
[0003]
As a method for calling a scene, for example, a method is used in which the scene number is incremented / decremented one by one with an INC / DEC switch, and the scene data of the incremented / decremented scene number is called. A method is also known in which a specific scene number is input using a numeric keypad, and a scene with that number is directly called.
[0004]
[Problems to be solved by the invention]
By the way, scene data is not stored for all consecutive scene numbers. However, in the conventional mixer apparatus, the scene number is increased or decreased one by one by the INC / DEC switch, so that all the scene numbers having no scene data must be turned. Therefore, the operation has become very complicated.
[0005]
In addition, many scenes are stored in the scene memory, but in a series of multiple scenes of events such as concerts and plays where a mixer is used, it is desired to easily call a specific scene that is an event delimiter There is a request. However, as described above, in order to move to a desired scene on the way, the “INC / DEC” switch must be operated many times, or the scene number of the scene must be directly input with the numeric keypad. there were.
[0006]
In view of the above-described problems in the prior art, the present invention eliminates the troublesome operation of turning over all scene numbers without scene data when calling a scene with the INC / DEC switch, and is a specific event delimiter. An object of the present invention is to provide a digital mixer that can meet a demand for easily recalling a scene.
[0007]

In order to achieve this object, the invention according to claim 1 is provided with a display means and an operation element on a panel, and arbitrarily mixes a plurality of acoustic signals input from a plurality of input systems to thereby output a plurality of output systems A digital mixer that outputs data for reproducing the setting state of the mixing process for each of a plurality of scenes, the latest data specified by a scene number, and a plurality of data specified by a scene number and a history number including the historical data stores, memory means for the scene for each scene stored blank flag indicating whether it is deleted, and the INC switch and DEC switch to increase or decrease the your scene number, scene and a numeric keypad for numeric input and number and the history number, the operation of the INC switch or DEC switch, or the Ten And means for specifying the scene corresponding to the scene number to the history number specified by the operation of chromatography, when a scene number is increased or decreased in response to the operation of the INC switch and DEC switch, corresponding to the scene number When the blank flag of a scene is turned on, a scene designating unit that automatically increments or decrements the scene number next to the scene number and designates the scene, and a store that instructs to save the current setting state of the mixing process In response to an instruction from the instruction means and the store instruction means, the current setting state of the mixing process is written in the storage means as the latest data of the scene designated by the scene designation means, and the blank corresponding to the scene The flag is turned off, and the data already stored as the latest data of the designated scene is A setting state writing unit to be stored in the storage unit as history data, a deletion instructing unit for instructing deletion of the designated scene, and the scene designating unit in accordance with an instruction from the deletion instructing unit A setting state erasing unit that turns on the blank flag corresponding to a scene, a recall instructing unit that instructs to recall scene data from the storage unit, and the scene designating unit according to an instruction by the recall instructing unit It is characterized by comprising setting state reproducing means for recalling scene data designated by a scene number or history number from the storage means and reproducing the setting state of the mixing process .
[0010]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0011]
FIG. 1 shows a functional configuration of a digital mixer according to an embodiment of the present invention. Reference numerals 101 to 105 denote inputs to the mixing process. MADin 101 indicates the input of the microphone signal from the analog / digital conversion input board. This board can input two channels with one board. ADin102 indicates the input of the line signal by the analog / digital conversion input board. This board can input 4 channels on a single board. Din 103 indicates input by the digital input board. One board can input 8 channels of digital input (however, two lines are used). The above three types of MADin101, ADin102, and Din103 can be added up to 80 boards. The number of boards can be increased by inserting them into the interface box. Here, up to 10 boxes that can hold 8 boards can be connected. Up to 4 inputs x 80, 320 inputs.
[0012]
The built-in effector 104 indicates inputs from eight effectors built in the digital mixer. Each is an effector that inputs a stereo signal, applies a selected effect, and outputs a stereo signal. The built-in equalizer 105 is an input from 24 equalizers built in the digital mixer. Each receives a single signal, performs equalizer processing, and outputs a single signal. Note that “single” indicates a single channel that is not stereo.
[0013]
The input patch 111 has an input channel (48 single inputs) and a stereo input channel from the above-described maximum 320 single inputs (MADin101, ADin102, Din103), built-in effector output (8 stereo outputs), and built-in equalizer output (24 single outputs). Arbitrary connection to (4 stereo inputs). The setting can be arbitrarily performed while the user looks at a predetermined screen.
[0014]
The input signal selected by the input patch 111 is input to the input channel 112. Similarly, the input signal selected by the input patch 111 is input to the stereo input channel 113. Both the input channel 112 and the stereo input channel 113 have the configuration shown in FIG. 2A described later. The difference between these is that the stereo left signal (L) and the right signal (R) are paired in the stereo input channel 113. It is a point to be controlled. From the input channel 112, it is possible to selectively output to any channel of the 48 MIX buses 114 or the stereo bus (Stereo_L / R) 115. Similarly, the stereo input channel 113 can selectively output to any channel of the MIX bus 114 or the stereo bus 115. In each of the input channel 112 and the stereo input channel 113, the transmission level to each MIX bus 114 and stereo bus 115 can be set independently. Further, it is also possible to selectively output from the input channel 112 and the stereo input channel 113 to a CUE_L / R bus 116 or a KEY_IN bus 117 described later.
[0015]
The MIX bus 114 mixes signals input from the input channel 112 or the stereo input channel 113. The mixed signal is output to the corresponding MIX output channel 122. The MIX bus 114 and the MIX output channel 122 are associated with each other in a one-to-one correspondence. The stereo bus 115 mixes signals input from the input channel 112 or the stereo input channel 113. The mixed stereo signal is output to the two stereo output channels 121 in parallel. The CUE_L / R bus 116 is a bus for confirming what signal is input to each channel. As will be described later, a CUE button is provided under each channel control, and when it is turned on, only the signal of that channel can be confirmed via this bus 116, for example, with headphones. The KEY_IN bus 117 is a bus with four channels for a single input, and is for controlling the compressor.
[0016]
In the stereo output channel 121, stereo L and R are always controlled in pairs. The output of the stereo output channel 121 is output to the output patch 124 and the matrix output channel 123. The MIX output channel 122 outputs the output from the MIX bus 114 to the output patch 124 or the matrix output channel 123. In the MIX output channel 122, the (2N + 1) th channel and the (2N + 2) th channel can be paired.
[0017]
The matrix output channel 123 can selectively input any number of signals from the stereo output channel 121 and the MIX output channel 122, and can further mix these selectively input signals. The signal processing configuration is the same as that of the stereo output channel 121 and the MIX output channel 122. The output of the matrix output channel 123 is output to the output patch 124.
[0018]
The output patch 124 can output from the above-described three types of output channels (72 single outputs + 2 stereo outputs) to a maximum of 192 single outputs (DAout, Dout), a built-in effector (8 stereo inputs), or a built-in equalizer (24 single inputs). Make arbitrary connections. DAout 131 indicates an output to the digital / analog conversion output board. One board can output 4 channels. Dout 132 indicates the output to the digital output board. This board can output 8 channels (one line is used). The output from the output patch 124 can also be output to the built-in effector 104 or the built-in equalizer 105.
[0019]
For simplification of drawings, input on the console side and talkback-in, etc., output on the console side and output such as cue-out, connection for insert effects, and connection for monitor output are omitted. doing.

The de-emphasis 211 is a filter that adjusts frequency characteristics. The noise gate 214 is a gate for closing (cutting the signal line) so that no noise remains when the signal level decreases. The compressor 215 is for performing automatic gain adjustment. The delay circuit 216 is used to perform phase alignment so that the musical sounds do not cancel each other when a plurality of speakers are placed in a concert hall or the like. A fader 217 is a volume for level adjustment. The configuration of the stereo input channel 113 is the same as that shown in FIG. However, in the stereo input channel 113, the stereo left signal (L) and right signal (R) are controlled in pairs.
[0021]
FIG. 2B shows a configuration of one output channel of the MIX output channel 122 of FIG. The output channel 202 includes a 6-band PEQ 221, a compressor 222, a delay circuit 223, and a fader 224. The configurations of the stereo output channel 121 and the matrix output channel 123 are basically the same as those in FIG. However, in the stereo output channel 121, the stereo left signal (L) and right signal (R) are controlled in pairs. As for the matrix output channel, a mixing unit that selectively mixes one or more of the stereo output channel and the MIX output channel set as the input source of the matrix output channel is provided in front of the 6-band PEQ. ing.

The CPU 304 detects the operation of the operation element 303 and the fader 302, and controls the operation of the DSP 308, the display content of the display 301, the position of the fader 302, and the like. The fader 302 is a so-called moving fader to which a motor is attached. The CPU 304 can detect the position of the fader 302 and can move the fader 302 to a designated position in accordance with an instruction from the CPU 304.
[0023]
The DSP (digital signal processor) 308 is a signal processing unit for performing mixer processing having the functional configuration as described in FIG. The DSP 308 is provided with connectors 1 to 10 (321 to 323) on the input side and connectors 1 to 6 (331 to 333) on the output side for inputting and outputting signals. One input connector 321 to 323 can be connected to either an analog / digital conversion box or a digital interface box as the interface box described in FIG. Up to eight A / D conversion boards (MADin 101 in FIG. 1) can be added to one analog / digital conversion box. Gain (volume) and polarity can be set for each analog / digital conversion input. Up to eight digital I / O boards (Din 103 and Dout 132 in FIG. 1) can be added to one digital interface box.
[0024]
In addition, either the digital / analog conversion box or the digital interface box can be connected to the one connector 331 to 333 on the output side of the DSP 308 as the interface box described in FIG. Up to eight D / A conversion boards (DAout 131 in FIG. 1) can be added to one digital / analog conversion box. Gain and polarity can be set for each digital / analog conversion output. Since the digital I / O board inserted into the digital interface box may be used for both input and output, in this case, the digital interface box on the input side and the output side of the DSP 308 are shared.

[0030]
FIG. 6B shows a detailed configuration of the MIX channel section 405. The MIX channel section 405 is a part for adjusting the level of the MIX output channel 122 of FIG. Reference numeral 630 denotes a set of operators corresponding to one channel of the MIX output channel 122, and several of them are arranged to constitute the MIX channel section 405. The configuration of the operator group 630 for one channel is the same as the configuration of the operator group 610 for the matrix channel section in FIG. The parts 631 to 636 correspond to the parts 611 to 616, respectively.
[0031]
FIG. 7 shows a detailed configuration of the control / memory section 408. The control / memory section 408 includes a direct recall switch 711, a preview switch 712, a history “return” switch 713, a recall switch 714, a store switch 715, an LED 716, a numeric keypad 717, an INC key 718, a DEC key 719, a cursor movement key 720, a track A pad 721, a left pad switch 722, a right pad switch 723, and a delete key 724 are provided.
[0032]
The direct recall key 711 is a switch for assigning a scene number to each switch and calling the scene with one touch. There are 12 direct recall keys 711, and 12 scenes can be directly called.
[0033]
The preview switch 712 is a switch for alternately switching between a preview mode and a non-preview mode each time it is turned on. The non-preview mode is a mode in which the current mixing state can be directly operated. In the non-preview mode, for example, when any controller or fader is operated, the current scene state is changed according to the operation. The preview mode is a mode in which the settings of other scenes can be recalled and checked or changed (previewed) while the current scene mixing state remains unchanged. The processing when the preview switch 712 is turned on will be described in detail with reference to FIG.
[0034]
The history “return” switch 713 is a switch for recalling the past setting of the scene stored for each scene. Processing when the history “return” switch 713 is turned on will be described in detail with reference to FIG.
[0035]
The recall switch 714 is a switch for instructing to call an arbitrary scene. Recalling a scene is performed as follows. In the preview mode, the scene number of the scene being previewed is displayed on the LED 716. In the non-preview mode, the scene number of the currently set scene is displayed on the LED 716. In this state, the decimal point is fixedly displayed on the display of the LED 716, and the display of the integer part of the LED 716 represents the scene number. The decimal part represents the past history (detailed later) of the scene having the scene number of the integer part. Here, by operating the numeric keypad 717 to input an arbitrary scene number (integer part) and turning on the recall switch 714, the (latest) scene having the scene number can be called. The numeric keypad 717 also has a decimal point key. After the integer part is turned on, the decimal point key is turned on, a numerical value after the decimal point is input, and then the recall switch 714 is turned on, so that past data of an arbitrary scene can be obtained. It can also be called directly.
[0036]
In either the preview mode or the non-preview mode, the scene can be called by the INC key 718 or the DEC key 719. When the INC key 718 is turned on when the LED 716 displays the scene number of the current scene, the (newest) scene having the next scene number whose integer part is larger than that scene number is called. In this case, since the blank deleted is set for the scene deleted by the delete key 724 as described later, when the INC key 718 is turned on, the blank scene is skipped and the next scene among the non-blank scenes is set. Shall be called. The DEC key 719 is the same as the INC key 718 except that the scene number advances in the direction of decreasing.
[0037]
A general processing procedure when changing the scene number by operating the INC key 718, the DEC key 719, or the numeric keypad 717 and the recall key 714 will be described with reference to FIG. In particular, a process of skipping blank scene data and increasing or decreasing the scene number when changing the scene number when the INC key 718 or the DEC key 719 is operated will be described with reference to FIG.
[0038]
After calling an arbitrary scene as described above in the preview mode or the non-preview mode, various settings as described in FIGS. 4 to 6 can be operated to change various settings of the scene. . Changing the setting in the preview mode does not affect the mixing state of the currently active scene. Changes in settings in non-preview mode are directly reflected in the current mixing state. In either the preview mode or the non-preview mode, the setting change is a temporary change. After the setting change, the store data 715 can be stored in the designated scene number by turning on the store switch 715. When the store switch 715 is turned on, an inquiry message as to which scene number is stored is displayed. In response to this, the store number (only the integer part) is input by the numeric keypad 717, and the store switch 715 is turned on again. The current scene state can be stored in the area of the scene number. Processing when the store switch 715 is turned on will be described with reference to FIG.
[0039]
By turning on the delete key 724, the scene of the current scene number can be deleted. However, even if the scene is deleted, the scene data is retained as data indicating the past history. Only a blank flag indicating that the scene has been deleted is set. The processing when the delete key 724 is turned on will be described with reference to FIG.
[0040]
The cursor movement key 720, the track pad 721, the left pad switch 722, and the right pad switch 723 are used when the user changes various settings with reference to the screen displayed in the section 403 (301 in FIG. 3) of the display unit. Used for.
[0041]
FIG. 9 shows a memory map of the data storage area secured in the flash memory of FIG. In the data storage area, arrays PD (1) to PD (100) for storing 100 patch data, arrays ND (1) to ND (100), 100 for storing 100 name data Arrays UD (1) to UD (100) for storing unit data, arrays SED (1) to SED (1000) for storing 1000 scene entry data, and 10,000 scene data are stored. Arrays SD (1) to SD (1000) are provided for this purpose.
[0042]
The patch data stored in the arrays PD (1) to PD (100) is data representing the connection state of the input patch 111 and the output patch 124 described in FIG. The name data stored in the arrays ND (1) to ND (100) are the input channel 112, the MIX output channel 122, and the MATRIX output channel described in FIG. 1, and names (short names, etc.) assigned thereto. It is the data which shows the corresponding relationship. The unit data stored in the arrays UD (1) to UD (100) are the setting data (such as gain and polarity) for each input of each input board connected to the input side interface box, and the output side interface box. Indicates setting data (gain, polarity, etc.) for each connected output.
[0043]
The scene entry data stored in the arrays SED (1) to SED (1000) is information for specifying one registered scene. The number of the subscript in this array corresponds to the scene number (integer part). For example, SED (2) corresponds to the scene with the scene number “2”.
[0044]
As shown in FIG. 9, one scene entry data includes a scene name SNAME, a pointer SDN indicating the latest scene data SD of the scene name, a blank flag BF, and a history number HN. The scene name SNAME is the name of the registered scene. The scene data SD pointed to by the pointer SDN is the latest data among the scene data of the scene. The blank flag BF indicates that the scene data body of the scene data SD pointed to by the pointer SDN is valid when the value is “0”. When the value of the blank flag BF is “1”, it indicates that the scene data body of the scene data SD pointed to by the pointer SDN is invalid (deleted). In this embodiment, when a scene is stored in an arbitrary scene number, the stored data is stored as the latest scene, and when the scene data of the scene number already exists, it is stored in the past scene data. Keep as. The history number HN is data indicating the number of scene data currently stored including past scene data. A single scene number (integer part) can hold up to 10 scene data.
[0045]
As shown in FIG. 9, one scene data includes a pointer NSDN to the next scene data SD in the history, a pointer PSDN to the previous scene data SD, the body of the scene data, a link PDL to the patch data, and name data. Link NDL and a link UDL to unit data.
[0046]
The pointer NSDN to the next scene data SD is a pointer that points to the previous scene data of the scene data. The pointer PSDN to the previous scene data SD is a pointer that points to the scene data that is one after the scene data (closer to the present). With these pointers NSDN and PSDN, the current scene data from the past of the same scene number is chained. Since there is no newer scene data for the latest scene data in a certain scene number, an identifier (for example, hexadecimal FF) indicating that fact is set in the pointer PSDN. Since there is no past scene data for the past scene data in a certain scene number, an identifier (for example, hexadecimal FF) indicating that fact is set in the pointer NSDN. Since the maximum value of the history number HN is 10, when the scene data chained by the pointers NSDN and PSDN is 10, and when new scene data is stored in the scene number, the oldest scene data Is destroyed.
[0047]
The decimal part of the scene number indicates when the scene data is a history. For example, in a scene whose scene number is 99, the latest scene data has a scene number of 99.0 (first scene data SD indicated by the pointer SDN), and the previous past scene data has a scene number of 99. .1 (the second scene data SD pointed to by the pointer NSDN of the first scene data SD), and the previous scene data before that has a scene number of 99.2 (the first scene data SD pointed to by the pointer NSDN). 3 scene data SD).
[0048]
The scene data itself contains settings for each input channel (effects, faders, output destination, output level, etc. for each channel), and settings for each output channel (input sources, input levels for each channel effect, fader, matrix output channel) Etc.), data such as built-in effector settings, built-in equalizer settings, and monitor settings are stored. In the link PDL to the patch data, the link NDL to the name data, and the link UDL to the unit data, pointers that respectively point to the patch data PD, name data ND, and unit data UD used in the scene are set.
[0049]
Note that the patch data PD, name data ND, and unit data UD were included in the scene data in the conventional mixer, so that the efficiency was poor in terms of storage capacity and response. However, these data are not always changed for each scene, and in many cases, these settings are not changed in a series of a plurality of scenes. On the other hand, the setting data included in the above-described scene data main body is data that is highly likely to be changed for each scene. Therefore, in this embodiment, the link PDL, NDL, and UDL are provided in the scene data, and if the data is the same even if the scene is changed, the link is made to the same data. Thereby, since it is not necessary to have these data for each scene data, the storage capacity can be suppressed. Even if the scene changes, if the data pointed to by the link PDL, NDL, or UDL does not change, the setting state does not need to be changed, and the response is fast. The digital mixer has a function for rearranging scenes using scene names and setting values as keys, but since each link is stored for each individual scene data, such rearrangement is performed. Even when the operation is performed, the setting contents for each scene are not destroyed.
[0050]
Although the processing procedure will be described later, when deletion of a certain scene is instructed (scene delete operation), the blank flag BF of the scene entry data SED of that scene is simply set to “1”. As a result, the deleted scene can be accessed by following the chain from the pointer SDN of the scene entry data SED.
[0051]
To change the setting of the patch data PD, name data ND, and unit data UD, a setting change screen for these data is displayed on the display section 403 by a predetermined operation, and the numeric keypad 717, the cursor movement key 720 described in FIG. This can be done by operating the track pad 721, the left pad switch 722, the right pad switch 723, and the like.
[0052]
FIG. 10 shows a processing procedure when the scene number is changed by operating the numeric keypad 717 and the recall key 714, or the INC key 718 or the DEC key 719 described in FIG. In step 1001, it is determined whether the current mode is a preview mode or a non-preview mode. The flag PN is a flag that is “1” in the preview mode and “0” in the non-preview mode. When in the non-preview mode, in step 1002, the scene number SN is changed according to the operation content, and the scene data corresponding to the changed scene number SN is loaded from the data storage area of FIG. 9 into the main work memory. At the same time, the corresponding control data is sent to the DSP 308, the setting of the DSP 308 is changed, and the process ends. When the preview mode is set in step 1001, the preview scene number PSN is changed in accordance with the operation content in step 1003, and the scene data corresponding to the changed preview scene number PSN is used for previewing from the data storage area of FIG. Load into work memory. In this case, the corresponding control data is not sent to the DSP 308.

FIG. 11 shows a processing procedure when the preview switch 712 of FIG. 7 is turned on. In step 1101, the flag PN indicating the preview mode or the non-preview mode is inverted. Next, in step 1102, it is determined whether the preview mode or the non-preview mode. In the non-preview mode, in step 1103, the main work memory is set to be used for panel control, and the process ends. Thereafter, the scene data developed on the main work memory (this data is reflected in the mixer processing in the DSP) can be changed by operating various operators on the panel. If the preview mode is set in step 1102, the contents of the main work memory are copied to the preview work memory in step 1104, and the current scene number SN is copied to the preview scene number PSN. In step 1105, the preview work memory is set to be used for panel control, and the process ends. Thereafter, the setting of the scene data in the preview work memory can be changed by various operators on the panel. In accordance with the data in the main work memory, the display contents of the display on the panel, the position of the operation element, and the mixer processing of the DSP are controlled. On the other hand, the display content of the display on the panel and the position of the operation element are controlled according to the data in the preview work memory, but the DSP mixer processing is not controlled.

FIG. 12 shows a processing procedure when the INC key 718 of FIG. 7 is turned on in the non-preview mode. The processing when the scene number is changed has been described with reference to FIG. 10, but FIG. 12 is a flowchart focusing on processing for changing a scene by skipping a blank scene and processing for calling data by following a link. .
[0055]
First, in step 1201, it is determined whether or not the current scene number SN is equal to or greater than the maximum scene number value MAX. If MAX has been reached, a message to that effect is displayed in step 1211 and the process is terminated. If the scene number is smaller than the maximum value MAX in step 1201, a value obtained by adding 1 to the integer part of the scene number SN is set as a new scene number SN in step 1202, and whether or not the scene is blank in step 1203. judge. Whether or not it is blank can be determined by referring to the blank flag BF of the scene entry data SED (FIG. 9) of the scene. When the scene of the scene number SN is blank, the process returns to step 1201.
[0056]
If not blank, in step 1204, the patch link PDL of the latest scene data of the scene number SN (integer part) is referred to, and the current setting state (scene data of the scene number SN when the processing of FIG. 12 is started) It is determined whether or not the patch link PDL is changed (whether both patch links PDL are the same). If it has been changed, the patch data PD is called in step 1205. Next, in step 1206, the name link NDL of the scene with the scene number SN is referred to and it is determined whether or not the current setting state (name link NDL of the scene data) has been changed. If it is changed, the name data ND of the name link is called at step 1207. Next, in step 1208, the unit link UDL of the scene with the scene number SN is referred to, and it is determined whether or not the current setting state (unit link UDL of the scene data) has been changed. If it has been changed, the unit data of the unit link is called in step 1209. Finally, in step 1210, the latest scene data indicated by the scene number SN (integer part) is loaded from the data storage area of FIG. 9 on the flash memory 305 to the main work memory, and the corresponding control data is sent to the DSP 308. To end the process.
[0057]
In FIG. 12, the process of turning on the INC key 718 in the non-preview mode has been described. However, when the DEC key 719 is turned on, the scene number is changed in a decreasing direction. In the preview mode, the called data is developed in the preview work memory instead of the main work memory, and the called data is not sent to the DSP 308.
[0058]
FIG. 13 shows a processing procedure when the fader is operated. FIG. 13A shows the case of the non-preview mode, and FIG. 13B shows the case of the preview mode. When the fader is operated in the non-preview mode, in step 1301, the data corresponding to the fader in the main work memory is updated with the detected value of the fader. In step 1302, control data corresponding to the fader is sent to the DSP 308, and the process is terminated. In the preview mode, in step 1311, the data of the fader in the preview work memory is updated with the detected value of the fader, and the process is terminated. In this case, the mixer process of the DSP 308 is not controlled according to the operation of the fader.
[0059]
FIG. 14 shows a processing procedure when the store switch 715 of FIG. 7 is turned on. When this process is started, a scene number to be stored is designated. In step 1401, one storage area for scene data SD is allocated in the data storage area of FIG. 9 in the flash memory. In step 1402, data in the main work memory (in the non-preview mode) or the preview work memory (in the preview mode) is copied to the allocated area SD. In step 1403, the history link of the scene number is updated so that the allocated area SD is at the head (latest scene data) (the area SD is connected to the head of the history link), and after the update The number of links in the history is adjusted to be 10 or less (when the number exceeds 10, the oldest scene data at the end of the link is separated from the link). In step 1404, the scene number entry pointer is updated to point to the allocated area SD, the history number HN is updated with the updated history link number, and the flag BF is set to “0”. To finish the process.

FIG. 15 shows a processing procedure when the delete key 724 of FIG. 7 is turned on. In step 1501, the blank flag BF of the scene number entry is set to “1”, and the process ends.
[0061]
FIG. 16 shows a processing procedure when the history “return” switch 713 in FIG. 7 is turned on. In step 1601, the pointer is traced from the current scene number SN to determine whether or not the end of the history (most past data) is reached. When the current scene is the most past data, the history cannot be returned any further, and the process is terminated. If it is not the end of the history, 0.1 is added to the scene number SN in step 1602, a recall process based on the new scene number SN is performed in step 1603, and the process ends. Although not shown here, it is also possible to recall from past data to the latest data by using a history “forward” switch.
