Description

  The present invention relates to an acoustic signal processing apparatus that performs signal processing on an acoustic signal and outputs the signal, and more particularly to an improvement in an event list function that executes events such as scene recall in the order of registration in the acoustic signal processing apparatus.

  In a conventionally known digital audio mixer, scene data having the current mixer setting state (various parameter values) as one scene is recorded in the scene memory for each scene, and 1 recorded in the scene memory. By recalling one scene, there was a function to quickly reproduce the values of various parameters indicating the setting state of the mixer corresponding to the scene all at once.

  In the conventional scene function, there is a selective recall function that can selectively set a range of parameters to be recalled for each scene when a scene is recalled. According to the selective recall function, only a part of all the parameters indicating the mixer setting state can be selectively recalled (see, for example, Patent Document 1 below).

  In addition, in a conventional digital audio mixer, for events such as scene recall, a plurality of events to be executed in sequence and data in which the execution timing data of each event are associated are stored, and the order in which each event is to be executed is stored. There is an event list function that executes events according to the order of the list using the event list arranged in the above (for example, see Patent Document 2 below).

  As an event execution method by the event list function shown in Patent Document 2, a method of automatically executing events that have reached the execution timing sequentially according to the progress of the time code from the outside, and 1 according to a manual operation by the user There was a way to execute one event.

  The manual operation for instructing the event execution includes the operation of the Direct button for executing the event pointed to by the current pointer position on the event list and the current pointer position on the event list one step forward. Next button operation for executing the event indicated by the pointer position, and operation for the Next button for executing the event indicated by the pointer position by returning the current pointer position in the event list to the previous position. (See page 6 of Non-Patent Document 1 below).

"PM1D V2 System Software Supplementary Manual", [online], created in 2005, Yamaha Corporation, [searched February 24, 2010], Internet <URL: http://www2.yamaha.co.jp/manual/ pdf / pa / japan / mixers / pm1dv2_en.pdf>

  When the range of parameters to be recalled is set by the selective recall function, the mixer setting state (execution result) after the scene recall execution differs depending on the mixer setting state immediately before the scene recall execution. This is because the mixer setting state immediately before the execution of the scene recall remains in the range excluded from the scene recall.

  In a mixer equipped with a selective recall function and an event list function, when any event in the middle of the event list is executed, if there is a range set by the selective recall function for that event, the mixer immediately before the scene recall based on the event is executed Depending on the setting state, the setting state (execution result) of the mixer after execution of the scene recall differs.

  As a result, simply executing any event in the middle of the event list failed to obtain the mixer settings (expected execution results) when the event list was executed in order from the top of the event list. . For this reason, the execution result expected for an arbitrary event in the middle of the event list (mixer setting state when the event list is sequentially executed from the top of the event list) cannot be called at an arbitrary timing.

  In order to avoid the above-mentioned inconvenience in the conventional technology, when an arbitrary event in the middle of the event list is executed, the scene is not set to the recall range by the selective recall function at that position (all parameters are targeted). It was inconvenient because we had to take a work-around of arranging events.

  The present invention has been made in view of the above points, and when executing any event in the middle of the event list, it is possible to obtain the same result as when executing from the top of the event list to that event. An object of the present invention is to provide an acoustic signal processing apparatus.

  According to the present invention, a current storage unit that stores a plurality of control data for controlling the current operation of the acoustic signal processing device, and a setting state of the plurality of control data stored in the current storage unit is set as one scene. A scene storage means for storing a plurality of scene data, and an event list means for registering a plurality of event data indicating events to be executed sequentially in order of events to be executed, wherein the event data is stored in the scene storage means The plurality of controls included in the scene to be recalled in the event for each of the plurality of event data registered in the event list means and the data indicating the event for instructing the recall of one stored scene By specifying a part of the control data as a range to be recalled, A range specifying means for selectively setting a range to be recalled, and specifying one of a plurality of event data registered in the event list means as an execution target according to a first operation of the user Normal execution means for executing scene recall based on one specified event data, based on the specified event data out of a plurality of scene data stored in the scene storage means The scene data of the scene to be recalled is specified, and based on the specified scene data, the control of the range specified by the range specifying means with respect to the specified event data among the control data stored in the current storage means A normal execution means for changing the value of the data, and a plurality of items registered in the event list means in accordance with the second operation of the user Trace execution in which any one of event data is designated as an execution target and scene recall is executed based on a plurality of event data from the first event registered in the event list means to the designated event Means for specifying scene data of each scene to be recalled based on the plurality of event data from the plurality of scene data stored in the scene storage means, and based on the specified scene data The acoustic signal processing apparatus includes a trace execution unit that changes the value of the control data in the range specified by the range specifying unit with respect to the event data among the control data stored in the current storage unit.

  According to the present invention, according to the first operation of the user, by overwriting the control data in the range specified by the user for the event data specified as the execution target (scene recall), An execution result of the scene recall (setting state of the acoustic signal processing device) based on the event data corresponding to the content of the immediately preceding current storage means can be obtained. On the other hand, according to the user's second operation, the control data in the range specified by the user is overwritten in the current storage means for the scene data of each event data from the top of the event list to the event data specified as the execution target. By executing (scene recall), regardless of the contents of the current storage means immediately before, the execution result by the constant trace execution means, that is, each event data from the top of the event list to the event data specified as the execution target It is possible to obtain an excellent effect that it is possible to obtain the setting state of the sound signal processing apparatus when the scene recall based on the above is performed.

This is a function that selectively restricts a part of the entire control data.

  The safe mode button 301 is a button for switching on / off of the “safe mode”, and the recall mode button 302 is a button for switching on / off of the “recall mode”. The safe mode is a mode in which a range to be excluded from scene recall targets (a range in which a setting state based on scene data is not reproduced) is selected on the recall filter setting screen 300. On the other hand, the recall mode is a mode in which a scene recall target range of a scene (a range in which a setting state based on scene data is reproduced) is selected on the recall filter setting screen 300. The “safe mode” and the “recall mode” are selectively switched on and off, and when one is on, the other is off. In the figure, hatching indicates that the button is on.

  The input channel selection unit 303 is a part provided with a button for selecting an input channel for changing the recall filter setting, and 24 input channel buttons 304 corresponding to each input channel of the input channel unit 23 are provided. Yes. The output channel selection unit 305 is provided with a button for selecting an output channel for which a recall filter is to be set. Twelve output channel buttons 306 corresponding to each output channel of the MIX output channel unit 25 are provided. Is provided. One of the input channel buttons 304 and the output channel buttons 306 operated by the user is selected as a control target of the parameter group selection unit 310. Each input channel button 304 and each output channel button 306 display the recall filter function on / off state for the corresponding channel according to the current mode (either safe mode or recall mode). The recall filter function acts on the channel for which the recall filter function is on. In the figure, hatching indicates that the recall filter function of the channel corresponding to the button is on.

  The parameter group selection unit 310 includes buttons 311 to 319 for switching selection or deselection for each parameter group and all parameters corresponding to the buttons 311 to 319 for the parameter group obtained by grouping the parameters of the signal processing channel. An ALL button 320 is provided for selecting or deselecting all at once. In the figure, hatching indicates that the parameter group corresponding to the button is selected. The recall filter function acts on the parameter group selected by the parameter group selection unit 310.

  Each button 311 to 320 provided in the parameter group selection unit 310 targets a parameter of a signal processing channel corresponding to the button selected immediately before in the input channel selection unit 303 or the output channel selection unit 305. The relevant parameter of the currently controlled channel is displayed in a state reflecting the setting contents (selected state). Therefore, when a new channel selection operation is performed in the input channel selection unit 303 or the output channel selection unit 305, the display states (selection states) of the buttons 311 to 320 of the parameter group selection unit 310 are newly selected. The setting contents (selected state) related to channel are switched.

  Buttons 311 to 319 of the parameter group selection unit 310 include FADER 311 (volume control parameter), ON 312 (ch on / off), PAN 313 (stereo pan), EQ 314 (equalizer), COMP 315 (compressor), GATE 316 (noise gate), SED_LV 317 ( Bus send level), SEND_ON 318 (bus send on / off), and Routing 319 (patch setting).

  Each parameter group corresponding to each of these buttons 311 to 319 is a set of one or a plurality of parameters constituting one function in the signal processing of each signal processing channel of the input channel unit 23 and the output channel unit 25. It is a group thing. Some parameter groups are composed of a plurality of parameters such as EQ 314, and others are composed of only one parameter such as ON 312. Each parameter group related to signal processing of these signal processing channels is provided for each signal processing channel. Some of these parameter groups are provided only in either the input channel or the output channel.

  The user uses each button of the input channel selection unit 303, the output channel selection unit 305, and the parameter group selection unit 310 to select or deselect each parameter group with respect to the “safe mode” and “recall mode” for each channel. Can be set. In the safe mode, the selected parameter group is excluded (overwrite restriction) from the scene recall target range, and the non-selected parameter group becomes the scene recall target range. Conversely, in the recall mode, the selected parameter group becomes the scene recall target range and is excluded (overwrite restricted) from the scene recall target range. In short, in either the safe mode or the recall mode, whether to restrict overwriting by the recall filter function (whether to be a scene recall target range) is set depending on the selection / non-selection state for each parameter group. Note that the parameter group selected in one mode is always deselected in the other mode. A channel for which at least one parameter group is selected in the “safe mode” or the “recall mode” has the recall filter function turned on in that mode.

  In addition, the effector selection unit 307 is provided with a button 308 for setting a recall filter for the insert effector parameter. With regard to the insert effector, all parameters related to one effector are handled as one set of parameter groups, and parameter groups are selected or deselected by the four buttons 308 provided in the effector selection unit 307.

  In the digital mixer 1, from the recall filter setting screen 300 as described above, for each of a plurality of event sets (events instructing scene recall) registered in the event list 110 described above, a scene to be recalled at that event. By designating a part of the control data included in the data as a scene recall target range (recall range), it is possible to selectively set a range for scene recall.

  Also, regarding the “recall safe function” that limits the scene recall target range (acting the filter function) in common for all scenes, is it overwritten by the recall safe function depending on the selection / non-selection status for each parameter group? Whether or not to be a scene recall target range can be set from a screen having the same configuration as the recall filter setting screen of FIG. According to the recall safe function, the scene recall target range is commonly set to one of the scene recall target ranges (the entire control data recorded in the current memory) for all scene recalls. Can be selectively limited to parts.

<Processing according to manual operation>
Processing executed by the CPU 10 in response to a button operation on the event list screen will be described with reference to the flowcharts of FIGS.

《Normal execution instruction》
When the next button 120 is operated, as shown in FIG. 7A, the CPU 10 sets the current position of the current pointer cp to the position of the next event set (the event set one line lower in the event list 110 of FIG. 5). (Step S1), based on the event set at the position of the moved current pointer cp, a normal execution process described later is executed (step S2). Here, the current pointer cp is data indicating the current position of the current pointer 118 in the event list 110 in FIG. 5 (the event set of the row indicated by the pointer 118). When the prev button 122 is operated, as shown in FIG. 7B, the CPU 10 sets the current position of the current pointer cp to the previous event set (the event set on the first line in the event list 110 in FIG. 5). ) (Step S3), and based on the event set at the moved cp position, a normal execution process described later is executed (step S4). When the exe button 121 is operated, the CPU 10 executes a normal execution process described later based on the event set at the current position of the current pointer cp as shown in FIG. 7C (step S5). In the normal execution process of step S2, S4, or S5, as will be described in detail later, one event based on the event data is executed with event data included in the event set at the position of the current pointer cp as an execution target.

<Trace execution instructions>
When the EXE button 123 is operated, the CPU 10 executes a trace execution process, which will be described later, based on the event set at the current position of the current pointer cp as shown in FIG. 7C (step S5). When the NEXT button 124 is operated, as shown in FIG. 7A, the CPU 10 moves the current position of the current pointer cp to the position of the next event set (step S1), and the position of the moved cp. Based on the event set, a trace execution process described later is executed (step S2). When the PREV button 125 is operated, as shown in FIG. 7B, the CPU 10 moves the current position of the current pointer cp to the position of the previous event set (step S3), and the moved cp Based on the event set at the position of, a trace execution process described later is executed (step S4). In the trace execution process of step S2, S4, or S5, as will be described in detail later, the event data included in the event set at the position of the current pointer cp is set as the execution target, and the execution target from the event set at the top of the event list is selected. A plurality of events based on each event set up to the event set are sequentially executed.

  When the Up button 102 or the Down button 104 is operated, the CPU 10 moves the current position of the current pointer cp to the previous event set or the next event set row as shown in FIG. (Step S6). Thereby, the current pointer 118 can be moved to an arbitrary position with respect to the event list 110. In steps S1, S3, and S6, the process of moving cp includes a process of rewriting cp data and a display update process of updating the current position of the current pointer 118 on the event list screen.

<< Automatic execution process >>
When the automatic execution function (Auto) is on, the event set is automatically executed in the order based on the event list based on the time code supplied by the time code supply means. When the automatic execution function (Auto) is on, the CPU 10 triggers the execution timing of the event set next to the current position of the current pointer cp (the event set one line lower in the event list 110 in FIG. 5). The processing shown in FIG. 8 is executed when the time code supplied by the time code supply means reaches the time of the execution timing of the event set. Here, the “next event set” has a trigger type of “time code type” or “interval type”. "Manual type" is not included because the execution timing by trigger data is not specified.

  When the time code supplied by the time code supply means has reached the time of execution time of the event set, the CPU 10 moves the position of cp to the event set having reached the time of execution time in step S7, In step S8, the contents of the event based on the event set at the moved cp position are executed by a normal execution process described later. By performing the process of FIG. 8 every time the execution timing of the event set after the current position of cp arrives, events based on a plurality of event sets can be sequentially executed in the order of the event list. Even if the automatic execution function is on, an event set whose trigger type is “manual type” is not executed unless the user gives an execution instruction by manual operation.

<Normal execution processing>
The procedure of the normal execution process executed by the CPU 10 in steps S2, S4, S5, and S8 will be described with reference to FIG. In step S10, the CPU 10 determines whether or not the event data ED (cp) in the event set currently indicated by the current pointer cp is data for instructing scene recall. Here, the event data ED (cp) in the index is designated by the current pointer cp as an execution target of the current normal execution process according to the first operation of the user (operation of any of the buttons 120 to 122). Event data.

  When the event data ED (cp) is a scene recall (YES in step S10), the CPU 10 copies all control data (all parameter values) currently recorded in the current memory to the scene recall buffer area. (Step S11). In step S12, the CPU 10 specifies one scene data (s (cp)) to be recalled based on the event data ED (cp) from the plurality of scene data stored in the scene memory. A process of copying the scene data (s (cp)) to the scene recall buffer area within the scene recall target range set for the scene is performed. The scene data to be recalled based on the event data ED (cp) can be specified by the scene number (s (cp)). By the range limited copy process in step S12, the contents of the current memory copied to the buffer area in step S11 are overwritten based on the scene data (range limited scene data) of the event data ED (cp). The operation of scene data range-limited copying will be described later.

  In step S13, the CPU 10 temporarily stops the control of the DSP unit 7 based on the current memory. In step S14, the CPU 10 copies the contents of the buffer area to the current memory. As a result, the contents of the current memory are overwritten with the scene data (scene-limited scene data) of the event data ED (cp). Since the operation of the DSP unit 7 is temporarily stopped in step S13, the content being copied from the buffer to the current memory (that is, the content being overwritten by the recall) is not reflected in the signal processing of the DSP unit 7. After the copying from the buffer to the current memory is completed, in step S15, the CPU 10 resumes the control of the DSP unit 7 based on the current memory overwritten with the range-limited copied scene data (s (cp)). Therefore, by performing the normal execution process in which the event data ED (cp) is designated as the execution target, the mixer 1 can set the parameter setting state based on the scene data (range-limited scene data) of the event data ED (cp). Is reproduced.

  In step S10, if the event data ED (cp) is not data for instructing scene recall (NO in step S10), the CPU 10 executes event processing based on the event data ED (cp) (step S16). . The event other than the scene recall is, for example, an event for outputting a control signal (MIDI signal or GPI signal) from the mixer 1 to the peripheral device.

<< Trace execution process >>
The procedure of the trace execution process executed by the CPU 10 in steps S2, S4, and S5 will be described with reference to FIG. In step S17, all control data (all parameter values) currently recorded in the current memory are copied to the scene recall buffer area. In step S18, the CPU 10 moves the temporary pointer tp to the position of the first event set in the event list based on the event list. The temporary pointer tp is data indicating the position of one event set currently being processed in the trace execution process.

  In step S19, the CPU 10 determines whether or not the position of the temporary pointer tp has reached the position of the current pointer cp. Here, the event data ED (cp) of the current pointer cp is event data designated as an execution target by the user's second operation (operation of any of the buttons 123 to 125). When the position of the temporary pointer tp has not reached the position of the current pointer cp (NO in step S19), in step S20, the CPU 10 stores the event data ED (tp) of the event set currently indicated by the temporary pointer tp in the scene. It is determined whether the data indicates a recall.

  When the event data ED (tp) is a scene recall (YES in step S20), in step S21, the CPU 10 should recall based on the event data ED (tp) from among a plurality of scene data stored in the scene memory. The scene data (s (tp)) is specified, and the specified scene data (s (tp)) is copied to the scene recall buffer area within the scene recall target range set for the scene. By the range limited copy process in step S21, the contents of the current memory copied to the buffer area in step S17 are overwritten based on the scene data (range limited scene data) of the event data ED (tp).

  In step S22, the CPU 10 moves the current position of the temporary pointer tp to the position of the next event set based on the event list. Then, the CPU 10 branches step S19 to NO until the temporary pointer tp reaches the current pointer cp, and repeats the processing of steps S19 to S22. Thereby, the range limited copy process in step S21 based on each event set from the top of the event list to the event data ED (cp-1) immediately before the current pointer cp can be executed in the order of the event list. As a result, the contents of the buffer area are determined based on the scene data (range-limited scene data) of each event data from the top of the event list to the event data ED (cp-1) immediately before the current pointer cp. It becomes the same state as the setting state of the mixer 1 at the time of execution.

  In the loop processing of steps S19 to S22, scene recall based on scene data (range-limited scene data) of each event data from the top of the event list to event data ED (cp-1) immediately before the current pointer cp. Is a process of overwriting scene data (range-limited scene data) to the contents of the buffer area, and does not reflect the result in the actual signal processing (overwrite the current memory) at each scene recall. . If the event data ED (tp) is an event other than a scene recall in the loop process of steps S19 to S22 (NO in step S20), the CPU 10 does not perform the process corresponding to the event and performs a temporary pointer in step S22. tp is moved to the next event set position. The loop process of steps S19 to S22 reproduces the same state as the setting state of the mixer 1 when the scene recall based on each event set from the top of the event list to the event set immediately before the current pointer cp is executed in the buffer area. It is because it aims at that.

  When the position of the temporary pointer tp reaches the position of the current pointer cp (YES in step S19), the CPU 10 instructs the scene recall in step S23 in the event data ED (cp) in the event set currently indicated by the current pointer cp. Determine whether the data to be used. When the event data ED (cp) is a scene recall (YES in step S23), the CPU 10 performs a range-limited copy of the scene data (s (cp)) of the event data ED (cp) in the buffer area (step S24). After temporarily stopping the control of the DSP unit 7 based on the control data of the current memory (step S25), the contents of the buffer area are copied to the current memory (step S26), and after the copying from the buffer to the current memory is completed, the current memory The control of the DSP unit 7 based on the control data is restarted (step S27).

  Prior to the recall of the scene (s (cp)) based on the event data ED (cp) in steps S25 to S27, the contents of the buffer area are changed from the top of the event list to the current pointer cp by the processing in steps S19 to S22. The scene recall of each event set up to the immediately preceding event set is the same as the setting state of the mixer 1 when it is executed. Therefore, by specifying the event data ED (cp) as an execution target and performing a trace execution process, a scene recall based on each event data from the event at the top of the event list to the current position of the cp is performed. The same setting state as when executed in order can be reproduced in the mixer 1.

  If the event data ED (cp) is not data for instructing scene recall in step S23 (NO in step S23), the CPU 10 controls the control signal (peripheral device) from the mixer 1 based on the event data ED (cp). Processing of other events such as an event for outputting a MIDI signal or a GPI signal is executed (step S28).

<Range restriction copy processing>
A procedure of processing for copying scene data corresponding to one scene (s) to the buffer area in steps S12, S21, and S24 will be described with reference to FIG. FIG. 12 is a diagram for explaining the data structure of the entire control data (parameter values) that form one scene in the current memory and the buffer area. The data structures in the current memory and the buffer area are common.

  As shown in FIG. 12, a plurality of parameters are grouped into a plurality of N parameter groups pg (1) to pg (Npg) in the current memory and the buffer area. Each parameter group pg includes a parameter group for each signal processing channel including one or more parameters used for signal processing of the signal processing channel (each button of the parameter group selection unit 310 on the recall filter setting screen 300 in FIG. 6). 3) and a parameter group for each insert effector. As described above, the recall filter function can be set for each parameter group pg.

  In the current memory and buffer area, a storage area (pg = 1 to Npg) is allocated for each parameter group pg. In the storage area allocated to each parameter group pg, the values of one or a plurality of parameters constituting the parameter group pg corresponding to each area are stored together as one parameter block PB. The parameter block PB is substantial data (values of one or more parameters) of the parameter group pg. The CPU 10 designates any one of the parameter groups pg (1) to pg (Npg), so that any one of the parameter blocks PB (1) to PB (Npg) corresponding to the designated parameter group pg is stored in the current memory. In addition, data can be written to and read from the buffer area.

  In step S29 of FIG. 9, the CPU 10 designates the first parameter group pg (1). Here, the head parameter group pg is a parameter group assigned to the head address in the current memory and buffer area (see FIG. 12). In step S30 and step S31, the CPU 10 checks whether or not the designated parameter group pg (1) is overwritten by the recall safe function or the recall filter function. If overwriting is restricted by the recall safe function (YES in step S30), the designated parameter group pg (1) is excluded from the scene recall target range in all scenes. Do not copy. If overwriting is restricted by the recall filter function (YES in step S31), the designated parameter group pg is excluded from the scene recall target range for the scene (s) that is the current processing target. Therefore, the copy process in step S32 described later is not performed.

  If the designated parameter group pg (1) is not overwritten by either the recall safe function or the recall filter function (NO in step S30 and step S31), the designated parameter group pg (1) is stored in the scene ( s) is the range of the scene recall target. In step S32, the CPU 10 reads out the parameter block PB (1) of the designated parameter group pg (1) from the scene memory in the scene data of the scene (s), and sets the parameter block PB (1). Copy to buffer area. As a result, the parameter group pg in the buffer area is overwritten with the parameter block PB (1) based on the scene data of the scene (s). The scene (s) is a scene (s (cp)) based on the event set at the position of the current pointer cp in the steps S12 and S24, and the event set at the position of the temporary pointer tp in the step S21. (S (tp)).

  In step S33, the CPU 10 designates the next parameter group pg. The next parameter group pg is a parameter group assigned to the address following the parameter group pg that has been designated immediately before in the current memory and buffer area (see FIG. 12). For example, in the above description, since it is assumed that the parameter group pg (1) is specified, the parameter group pg (2) becomes the next parameter group pg. And CPU10 performs the process of step S31-S32 about the parameter group pg designated by the said step S33. As a result, when the designated parameter group pg is not overwritten by either the recall safe function or the recall filter function (NO in step S30 and step S31), the parameter block PB (pg) of the designated parameter group pg ) Is copied to the buffer area, the parameter group pg in the buffer area is overwritten with the parameter block PB (pg) (step S32).

  The CPU 10 repeats the processes in steps S31 to S33 until the process for the last parameter group pg (Npg) is completed (step S34). As a result, parameters based on the scene data are set for each parameter group pg in the scene recall target range excluding the parameter group pg overwritten by the recall filter and recall safe among all the parameter groups pg (1) to pg (Npg). Block PB can be copied to the buffer area. In FIG. 12, parameter blocks PB (1), PB (4), PB (5),... Overwritten (within the scene recall target range) are indicated by hatching. As described above, according to the process of FIG. 9, the scene (s) to be recalled is selectively copied to the buffer area for each parameter group pg in the range set as the scene recall target range (range limited copy). Can do. Therefore, for example, parameter groups pg outside the scene recall target range such as parameter groups pg (2), pg (3), pg (6)... In FIG. Data can be left behind.

<Summary>
The normal execution process (FIG. 9) is performed in response to the first operation of the user (any one of the buttons 120 to 122). In this case, for the scene data (s (cp)) of the event data ED (cp) of the current pointer cp, the normal execution is performed by copying the parameter block PB for each parameter group pg within the scene recall target range to the buffer area. The parameter block PB of each parameter group pg in the scene recall target range is overwritten on the setting contents of the current memory at the time when the processing instruction (first operation by the user) is performed. Regarding the parameter group pg outside the scene recall target range, the setting contents of the current memory immediately before executing the event (scene recall) by the normal execution process (for example, parameter groups pg (2), pg (3), pg (6) ...) remains. Accordingly, the scene recall result of the event data ED (cp) differs depending on the contents of the current memory immediately before.

  On the other hand, when the trace execution process (FIG. 10) is performed according to the user's second operation (operation of any of buttons 123 to 125), the event data immediately before the current pointer cp from the top of the event list. For the scene data of each event data up to ED (cp-1), the parameter block PB for each parameter group pg within the scene recall target range is copied in a range limited to the buffer area (steps S17 to S22), and thereafter For the scene data (s (cp)) of the event data ED (cp) of the current pointer (cp), the parameter block PB for each parameter group pg within the scene recall target range is copied to the buffer area (step S24). Therefore, in the case of trace execution, the scene recall result based on the event data ED (cp) is always based on the scene data of each event data from the top of the event list to the event data ED (cp) of the current pointer cp. The setting state when the scene is recalled within the scene recall target range for each event (scene) is reproduced.

  Thus, in the mixer 1 of the present embodiment, based on the event data ED (cp) at an arbitrary position cp in the event list in accordance with the second operation of the user (operation of any of buttons 123 to 125). Only by performing the trace execution process, a constant current memory setting state can always be obtained as a scene recall result based on the event data ED (cp), regardless of the contents of the immediately preceding current memory.

  Further, according to the automatic execution function of FIG. 8, the normal execution process based on each event data after the position of the current pointer 118 is automatically performed. By using this automatic execution function in combination with the trace execution function, the setting state when the scene recall from the beginning of the event list to the event data ED (cp) at an arbitrary position cp is first reproduced by the trace execution function. A plurality of events after the position cp can be automatically executed thereafter. That is, even when automatic execution is performed from the middle of the event list, the same execution result as when automatic execution is performed from the top of the event list can be obtained.

<Modification of event list screen>
In the event list screen of FIG. 6, only the EXE button 123 may be provided as a button (second operation input button) for instructing trace execution. As another configuration example, a button for switching on / off of “trace execution mode” is provided as an event execution mode without providing buttons 123 to 125 for instructing execution of trace, and when “trace execution mode” is on, “prev ”122,“ exe ”121, or“ next ”120, the same trace execution process as when any of“ PREV ”125,“ EXE ”123, or“ NEXT ”124 is operated Or a configuration in which trace execution processing is performed in response to an operation of “exe” 121 when “trace execution mode” is on (a configuration in which operations of “prev” 122 and “next” 120 are disabled). There may be.

  It should be noted that, as a scene recall result based on event data ED (cp) in the middle of the event list, a constant current memory setting state can always be obtained regardless of the content of the previous current memory. The automatic execution function is not essential for the configuration to obtain the effect. That is, the present invention can be applied to an acoustic signal processing apparatus having a configuration that does not have an automatic execution function.

  Further, the trigger data of the event set may be only one of “time (absolute time)” information related to the timing code type or relative time information related to “interval type”. Further, if the trigger type of the event set is only manual type, the trigger data of the event set is not necessary. That is, the event list may be obtained by sequentially registering a plurality of event data having no trigger data.

  The mixer 1 to which the present invention is applied may be configured such that the operation panel 2, the waveform I / O 6, and the DSP unit 7 are housed in one housing, or an independent device for each function. It may be a mixing system that connects the devices via a network. Further, the operation panel 2 may have a structure in which independent hardware such as a display and a ch strip group is combined for each functional element.
