  The plug-in processing unit 30 can perform signal processing using various plug-in components (hereinafter simply referred to as “plug-in”) on the sound signal being processed by the mixing processing unit 20. The plug-ins include those that realize the functions of effectors that add sound effects, such as reverb, delay, chorus, graphic equalizer, and compressor. The plug-in may have a function of processing sound signals of a plurality of channels. However, in order to simplify the following description, it is assumed here that the sound signals of 1 channel are processed.

When using a plug-in, for example, in a signal processing performed by the mixing processing unit 20, a sound signal from a certain block is taken out at a predetermined position between the certain block and the next block, and is transmitted via the audio bus 23. Are supplied to the plug-in processing unit 30, plug-in signal processing is performed on the sound signal, and the processed sound signal is returned to the mixing processing unit 20 via the audio bus 23 and supplied to the next block. To do. Moreover, the supply destination of the processed sound signal may be different from the position where the sound signal is extracted. For example, a signal extracted from the input channel (channel) and processed may be supplied to the output channel.
Various processing parameters for controlling sound signal processing performed by the plug-in processing unit 30 are also included in the above-described current data.

Next, FIG. 2 shows a block diagram of a sound signal processing function realized by the waveform I / O 19, the mixing processing unit 20, and the plug-in processing unit 30.
As shown in FIG. 2, the sound signal processing in the mixing processing unit 20 includes an input patch 43, an input ch 44, a mixing (MIX) bus 45, a MIX output ch 46, and an output patch 47.

  In the input patch 43, any one of the plurality of analog input ports of the analog input unit 41 of the waveform I / O 19 and the plurality of digital input ports of the digital input unit 42 is patched to each of the 12 input channels 44 ( Assignment), and the sound signal from the assigned input port is supplied to the input channel. In each input channel, the sound signal from the input patch 43 is subjected to signal processing by a series of processing blocks such as an equalizer and a compressor, and the processed sound signal is converted into one of the eight MIX buses 45 or Send to multiple buses. At the time of transmission, the level of the sound signal to be transmitted can be individually changed for each bus.

Each MIX bus 45 mixes the sound signal input from each input channel 44, and sends the resulting sound signal to the 8 channel MIX output channel 46 provided for each system of the MIX bus 45.
In each MIX output channel 46, the sound signal input from the MIX bus 45 is subjected to signal processing by a series of processing blocks such as an equalizer and a compressor, and the processed sound signal is sent to the output patch 47.
In the output patch 47, each of the MIX output channels 46 is patched with any one of a plurality of analog output units 48 and a plurality of digital output units 49 provided corresponding to each output terminal of the waveform I / O 19; The sound signal of each MIX output channel is output from the output unit at the patch destination.

Insert points are provided at predetermined positions between a series of processing blocks of each input channel and at predetermined positions between a series of processing blocks of each output channel. And this insert point and the plug-in 50 arrange | positioned at the plug-in process part 30 are connected, the sound signal in arbitrary insert points is input into the plug-in 50, and it processes, The signal after a process is arbitrary insert You can return to points. More specifically, the sound signal output from the processing block preceding the insert point on the input side is insert-outputted and transmitted to the plug-in processing unit 30, input to the plug-in 50, processed, and the processed signal. Can be returned from the plug-in processing unit 30 to the mixing processing unit 20 and used for signal processing subsequent to the insert point on the output side. A plurality of insert points may be provided in one channel so that the user can select a point to be used.
In addition to this, a sound signal output from an arbitrary channel may be input to the plug-in 50 for processing, or a sound signal processed by the plug-in 50 may be supplied to an input of an arbitrary channel. it can.

Next, processing resources of the plug-in processing unit 30, and execution modes and procedures of plug-in processing using the processing resources will be described with reference to FIGS.
FIG. 3 is a diagram illustrating processing resources of the plug-in processing unit 30, and FIGS. 4 and 5 are diagrams illustrating examples of execution modes of plug-in processing using the processing resources of the plug-in processing unit 30, respectively. .

  As illustrated in FIG. 3, the plug-in processing unit 30 includes m (m is an integer equal to or greater than 1) DSPs from the first DSP 31-1 to the m-th DSP 31-m. In order to assign processing resources by simple processing, it is desirable that the DSPs have exactly the same capability, but the present invention is not limited to this.

Each DSP 31-x (x is an integer from 1 to m) is n (n is an integer of 1 or more) from the first processing timing 31-x-1 to the n-th processing timing 31-xn. Has processing timing. Each processing timing is obtained by dividing one sampling period of the sound signal to be processed by n, and indicates the computing capability that the DSP 31-x can provide within that period.
Each DSP 31-x further includes a DSP memory 32-x for storing a program to be executed at each processing timing and sound data to be processed.

  Each of the above DSPs 31-x executes the program stored in association with the processing timing of the DSP memory 32-x at each processing timing 31-x-1 to 31-xn. The signal processing at the processing timing is executed. The signal processing at each processing timing 31-x-1 to 31-xn is performed by reading out one sample of the sound signal stored in the DSP memory 32-x at the input address corresponding to the processing timing, The sound signal of the processing result according to the above is written in one sample at an output address corresponding to the processing timing in the DSP memory 32-x (a program is created as such).

An output address corresponding to a certain processing timing 31-xy (y is an integer from 1 to n-1) is an input address corresponding to the next processing timing 31-x- (y + 1). . In this embodiment, the input address and the output address corresponding to each processing timing are fixed.
Accordingly, each DSP 31-x can perform processing while sequentially transferring sound signals between a plurality of programs at a plurality of continuous processing timings. This makes it possible to execute signal processing that is not substantially completed within one processing timing.
When causing the plug-in processing unit 30 to execute signal processing related to a certain component, as shown in FIG. 4 or FIG. 5, processing resources may be allocated to the component.

FIG. 4 is an example of an execution state when the DSP of the plug-in processing unit 30 executes the plug-in A processing that can be executed with the processing capability of four DSP processing timings.
In this case, the plug-in program A that defines the processing contents of the plug-in A is created by dividing the plug-in program A into four plug-in program parts A1 to A4 that can be executed by the DSP 31-x within one processing timing. . Then, four processing timings (here, the first to fourth processing timings 31-x-1 to 4) of the DSP 31-x are assigned to the plug-in A, and are associated with the processing timings 31-x-1 to 4-4. Then, the plug-in program parts A1 to A4 are loaded into the DSP memory 32-x.

  Then, at the first processing timing 31-x-1, the DSP reads the sound signal from the input address X1, executes the process by the plug-in program component A1, and writes (overwrites) the resultant sound signal to the output address X2. ). At the second processing timing 31-x-2, the sound signal is read from the input address X2, the process by the plug-in program component A2 is executed, and the resulting sound signal is written (overwritten) to the output address X3. Similarly, when the processing is executed up to the fourth processing timing 31-x-4, the sound signal obtained as a result of the sequential processing by the plug-in program components A1 to A4 on the sound signal stored at the address X1 becomes the address. Stored in X5.

  Accordingly, the sound signal at the input side insert point of the mixing processing unit 20 is written to the address X1 for each sampling period, and the sound signal at the output side insert point of the mixing processing unit 20 is stored for each sampling period. By writing to the address, the result of performing plug-in A processing on the sound signal at the input side insert point can be supplied to the output side insert point. Such data transmission setting for input / output to / from plug-in A is also referred to as a “patch”, like the input patch 43 and the output patch 47.

  Note that the processing itself according to each of the plug-in program parts A1 to A4 can be executed if there is no patch setting and no meaningful sound signal is written in the address X1, as long as the processing timing is assigned. is there. In this case, the sound signal of the processing result is also meaningless data, but if the output side patch is not set, the processing result does not affect the signal processing of the mixing processing unit 20.

FIG. 5 is an example of an execution state when the DSP of the plug-in processing unit 30 executes the plug-in B processing that can be executed with the processing capability of three DSP processing timings.
In this case, if the three processing timings of the DSP 31-x (here, the first to third processing timings 31-x-1 to 3) are assigned to the plug-in B, the processing of the necessary plug-in program parts B1 to B3 is performed. Can be executed. The final processing result is written to the output address X4 at the third processing timing 31-x-3. Therefore, the address X4 may be patched with the output side insert point.

  As described above, in order to cause the plug-in processing unit 30 to effectively execute signal processing related to a plug-in, the processing resource is set to the same number of processing timings as the plug-in program components constituting the plug-in. As well as input / output patches. The processing timing assigned to the plug-in is also referred to as a “slot” in the sense that the plug-in can be placed.

Next, FIG. 6 shows an example of a plug-in arrangement screen for accepting the processing resource assignment and patch setting described above and displaying the current state.
A plug-in arrangement screen 200 shown in FIG. 6 is displayed on the display unit 17 by the CPU 11 functioning as a display control unit, and includes a plug-in arrangement unit 210, a cursor operation unit 220, a plug-in selection unit 230, a plug-in setting unit 240, an arrangement. A button 251, a delete button 252, and a close button 253 are provided.

  Among these, the plug-in arrangement unit 210 is an area for displaying an allocation state of processing resources to plug-ins. In this example, 16 squares arranged in a row correspond to processing resources of one DSP in the plug-in processing unit 30, and each square corresponds to one processing timing. Therefore, in the example of FIG. 6, the plug-in processing unit 30 includes 24 DSPs from a to x, and these DSPs have 16 processing timings.

  Further, the plug-in arrangement unit 210 displays which processing resource is assigned to which plug-in for use by arranging icons corresponding to the plug-in so as to overlap each other. For example, the icon 212 indicates that the first to sixth processing timings of the DSP 31-a are assigned to the reverb plug-in. The icon 213 indicates that the thirteenth to fourteenth processing timings of the DSP 31-a are assigned to the graphic equalizer plug-in.

The size of each icon also indicates how many processing timings need to be allocated in order to use the function of the corresponding plug-in (how many slots are required to arrange the plug-in). A cell in which no icon is arranged indicates a currently available processing resource (slot).
Here, one column of cells corresponds to one DSP, but the present invention is not limited to this, and a plurality of columns may correspond to one DSP. One DSP having processing timing of 16 × 24 = 384 may be represented by the display of FIG.

In addition, a cursor 211 is displayed on the plug-in arrangement unit 210 and can be operated by the cursor operation unit 220. The size of the cursor 211 is the size of the icon of the plug-in currently selected by the plug-in selection unit 230.
The cursor operation unit 220 includes a knob 221, a cursor position display unit 222, and a resource display unit 223.

  The knob 221 is an operator for moving the cursor 211. The user can move the cursor 211 left and right by a drag operation after the knob 221 is selected by touching or a physical operation element such as a rotary encoder to which the knob 221 is assigned. Here, it is assumed that processing resources that span multiple DSPs are not allocated to the plug-in, and correspondingly, if the end of the cursor 211 reaches the end of the column, the cursor 211 is moved forward or backward. Move to the next row.

  The cursor position display unit 222 is an area for displaying the coordinates of the position of the cursor 211 in a combination of alphabets and numbers displayed on the plug-in arrangement unit 210. When the cursor 211 extends over a plurality of squares, the coordinates of a predetermined reference position such as the leftmost square are displayed.

  The resource display unit 223 is an area for displaying the number of available processing timings. When the cursor 211 is in a square where no icon is arranged, the number of consecutive empty squares including the square is used as the number of processing timings that can be used without affecting the plug-in already arranged at the cursor 211 position. indicate. When the cursor 211 is in the square where the icon is arranged, the number of squares occupied by the icon can be used at the position of the cursor 211 without affecting plug-ins other than the plug-in arranged at that position. Displayed as the processing timing number. When the cursor 211 covers a plurality of squares, the resource display unit 223 also displays according to the state of a predetermined reference position, such as the leftmost square. In the example of FIG. 6, 6 slots are displayed on the resource display unit 223 based on the size of the reverb plug-in arranged in the leftmost square “d3” of the cursor 211.

  Next, the plug-in selection unit 230 is an area for accepting selection of the type of plug-in to be arranged in the plug-in arrangement unit 210. When the user touches the plug-in selection unit 230, a list of plug-in types that can be arranged is displayed based on the component data in FIG. 7, and a type can be selected from the list. The plug-in selection unit 230 displays an icon 231 indicating the selected plug-in, and the name display unit 232 displays the name of the selected plug-in. It is possible to select no type, and in this case, the size of the cursor 211 is one square. This state can also be regarded as an editing mode suitable for editing the arranged plug-in.

  The plug-in setting unit 240 is an area for displaying a setting state of a plug-in that has been arranged at the position of the cursor 211 (the above-described reference position in the case of a plurality of cells) and accepting settings related to the plug-in. . The settings to be displayed and received by the plug-in setting unit 240 are the patch and operation mode settings related to the plug-in. The input source setting unit 241 sets the input side patch, the output destination setting unit 242 sets the output side patch, Display and accept.

  When the user touches the input source setting unit 241, a list of input source candidates for signals to the plug-in is displayed, and the user can select an input source from the list. Candidates can be the channels provided in the digital mixer 10 such as the input channel 44 and the MIX output channel 46, for example. However, there may be other options such as allowing the output of other plug-ins to be specified. Further, when a plurality of insert points are provided in one channel, it is possible to select which one of the input points from the list or the operation unit separately prepared. In any case, when the user selects an input source, the digital mixer 10 should transmit a sound signal from the input source to the input address corresponding to the beginning of the processing timing assigned to the plug-in to be set. , The setting is saved as a patch setting, and the selected input source is displayed on the input source setting unit 241. In the example of FIG. 6, it is displayed that the insert point behind the fader (AF) of the fourth input channel is the input source.

  When the user touches the output destination setting unit 242, a list of output destination candidates for signals to the plug-in is displayed, and the user can select an output destination from the list. The candidate list may be the same as that of the input source, but is not limited thereto. In any case, when the user selects the output destination, the digital mixer 10 should transmit the sound signal from the output address corresponding to the end of the processing timing assigned to the setting target plug-in to the output destination. While saving as a patch setting, the selected output destination is displayed on the output destination setting unit 242. In the example of FIG. 6, it is displayed that the insert point behind the fader (AF) of the fourth input channel is the output destination.

  In addition, the mode setting unit 243 displays the type of plug-in (“Reverb” in the example of FIG. 6) and also indicates whether the operation mode is insert or send / return. Of these, the insert mode is a mode in which a path through which a sound signal directly flows from the input source is cut, and the sound signal is made to flow to the output destination through all plug-ins. In this case, the plug-in functions as an insert effect. On the other hand, the send / return mode mixes the sound signal that has been processed by the plug-in and the sound signal that has flown without going through the plug-in at the output destination, taking advantage of the path through which the sound signal flows directly downstream from the input source. Thus, this mode is used for downstream signal processing.

  Whether the operation mode of each plug-in is insert or send / return is automatically determined by the digital mixer 10 by setting a patch related to the plug-in. If the input source of a signal to a certain plug-in is an insert point of any channel, the plug-in operates in the third mode, and if the input source is other than that, that is, the output of any channel, The plug-in operates in send / return mode. If there is no setting for either the input source or output destination, such as immediately after plug-in placement, the send / return mode is recommended. In the example of FIG. 6, an underline indicates that the current operation mode is the send / return mode.

  When a predetermined operation such as a double tap is performed on the mode setting unit 243, a GUI (graphical user interface) for accepting setting of parameters used by the plug-in for signal processing based on the display data shown in FIG. A pop-up is displayed, and the user can set parameters by operating the GUI.

Next, the placement button 251 is a button for instructing to place the plug-in selected by the plug-in selection unit 230 at the position of the cursor. Patches are set separately after the plug-in is placed.
The delete button 252 is a button for instructing to delete the plug-in arranged at the cursor position. When a plug-in is deleted, the patches set for that plug-in are also automatically deleted.
The close button 253 is a button for closing the plug-in arrangement screen 200.

  Next, FIG. 7 and FIG. 8 describe data that the digital mixer 10 refers to and creates in relation to the plug-in and its arrangement. FIG. 7 shows an example of data indicating available components, and FIG. 8 shows an example of data indicating the arrangement state of plug-ins. 7 and 8 show only data in a range related to the description of the present embodiment, and of course, there may be data other than those shown here.

  First, the digital mixer 10 stores the component data shown in FIG. 7 in a storage unit (second storage unit) such as the flash memory 12 as data defining the types of components that can be used in the digital mixer 10. However, all or part of the component data is stored in a storage medium connected to the other I / O 16 or a storage unit of an external device connected via a network, and the digital mixer 10 is used as necessary. It is also possible to read this out.

  Here, it is assumed that the only component that can be used is the plug-in component, and the component data defines the number of plug-in types p that can be used and the contents of each type. Including data. If a component other than a plug-in is also available, prepare the data for that component as well. In addition to this, the component data includes data of an Unknown component (unknown component).

Each plug-in type data includes a type ID, the number of slots, plug-in program parts, parameter configuration data, and display data.
Among these, the type ID is identification information for specifying the plug-in type.
The number of slots t indicates the amount of processing resources that need to be allocated to the corresponding type of plug-in in terms of the number of DSP processing timings.

Each plug-in program component is a program for causing the DSP to execute at each processing timing, and the function of the corresponding type of plug-in is realized by the components # 1 to #t.
The parameter configuration data is data indicating the configuration of parameters used by the corresponding type of plug-in for signal processing. This data includes data such as necessary parameter items and values that each item can take.
The display data is data for displaying the plug-in, such as an icon for displaying the plug-in of the corresponding type on the plug-in arrangement screen 200 and GUI data for receiving parameter settings.

The data of the Unknown component is data used when a scene (described later) read by the digital mixer 10 includes a type of plug-in that is not defined by the component data.
This Unknown component data includes a type ID indicating Unknown, a plug-in program part for passing (passing as it is) or cutting (may stop sound or mute) the sound signal to be processed, and a component Are included in the plug-in arrangement screen 200. It is desirable that the plug-in program parts have contents that can be executed continuously at an arbitrary number of processing timings. Since this is the case here, only one plug-in program part needs to be prepared. Further, the parameter may be a fixed value incorporated in the program part, and it is not necessary to accept editing thereof, so parameter configuration data and GUI data are unnecessary.

  Further, the digital mixer 10 stores scene data and a current scene shown in FIG. 8 as arrangement data indicating the arrangement state of components. The current scene is data to be reflected in signal processing executed by the current plug-in processing unit 30 and signal transmission related thereto. The digital mixer 10 stores this current scene in a storage unit (first storage unit) such as the RAM 13. The scene data is data created and stored in advance so that it can be read out and used as a current scene as necessary. The digital mixer 10 stores this scene data in a storage unit such as the flash memory 12, but all or part of the scene data is connected to other storage media connected to the I / O 16 or via a network. It is also conceivable that the data is stored in a storage unit or the like of the external device to be read and used as necessary.

The scene data includes the number of scenes s indicating the number of stored scenes, and data of the first to sth scenes. Each of the first to s-th scenes corresponds to one arrangement data.
Each scene includes a scene ID, the number of arranged plug-ins, plug-in data, and patch data.

Of these, the scene ID is identification information for specifying a scene.
The arrangement plug-in number d is data indicating the number of plug-ins arranged in the corresponding scene.
Each plug-in data is data indicating a plug-in arranged in the corresponding scene, and first to d-th plug-in data corresponding to each plug-in is created. Even when a plurality of plug-ins of the same type are arranged, plug-in data corresponding to each individual is created.
The patch data is a collection of patch information set for each plug-in.

The plug-in data includes a plug-in ID, a type ID, a start slot, a final slot, an insert / send return, and parameter data.
Among these, the plug-in ID is identification information for specifying an individual plug-in in the scene.
The type ID is an ID indicating the type of the corresponding plug-in, and the digital mixer 10 searches the component data using the type ID as a key, and acquires detailed information about each plug-in arranged in the scene. Can do.

The start slot and the final slot are data indicating the arrangement position of the corresponding plug-in on the plug-in arrangement screen 200, that is, the processing resource assigned to the corresponding plug-in, and indicate the position of the beginning and the end of the arrangement, respectively. Each position can be specified by the DSP 31 in the plug-in processing unit 30 and its processing timing. The length from the start slot to the last slot matches the number of slots in the plug-in.
The insert / send return is data indicating the operation mode of the plug-in. The value of this data is automatically determined based on the patch setting. If it is necessary to determine whether each plug-in operates in the insert or send / return operation mode based on the patch settings whenever necessary, the distinction between insert / send return must be prepared as explicit data. There is no.
The parameter data is a parameter value used by the corresponding plug-in for signal processing. The configuration is based on parameter configuration data corresponding to the type of plug-in.

The patch data includes the number of data z and information on the connection source and connection destination of the z set.
The data number z indicates the number of transmission source and transmission destination information included in the patch data.
The transmission source and the transmission destination are data defining a transmission source and a transmission destination of signal transmission performed for patching the plug-in. For the transmission source and the transmission destination, the position on the mixing processing unit 20 side is based on the position of the insert point (or the address storing the sound signal processed by the mixing processing unit 20), and the position on the plug-in processing unit 30 side is shown in FIG. Further, it can be specified by the address of the DSP memory described with reference to FIG. It is assumed that at least one of the transmission source and the transmission destination is in the plug-in processing unit 30.

  Which set defines the patch for which plug-in does not need to be maintained as explicit data, but it is not precluded. Even if there is no explicit data, the set whose destination is the address corresponding to the start slot of a certain plug-in indicates the patch on the input side for that plug-in, and the address corresponding to the last slot of the certain plug-in It can be easily understood by the digital mixer 10 that the transmission source set indicates the output side patch for the plug-in.

  The data structure of the current scene is the same as the data structure of each scene described above. Therefore, the digital mixer 10 can reflect an arbitrary scene stored in the signal processing or the like that is executed by the plug-in processing unit 30 by copying the scene to the storage area of the current scene. It is also possible to store the current scene data at an arbitrary time point in the scene data as one scene so that it can be read later.

  The scene data as described above or the scenes included in the scene data can be recorded on a portable recording medium and carried, or transmitted via a network, and can be read and used by another digital mixer. On the other hand, the digital mixer 10 uses the scene data created and saved by another digital mixer in the same manner as the scene data of FIG. 8, or the individual scene data included therein is used as the scene data of FIG. It can also be added to the data.

  In addition, the arrangement of the plug-ins and the setting of patches made on the plug-in arrangement screen 200 of FIG. 6 are reflected in the current data. That is, if a plug-in is newly arranged, the digital mixer 10 adds plug-in data corresponding to the arranged plug-in to the current scene, and conversely if the plug-in is deleted, a plug indicating the plug-in is added. Delete in-data from the current scene. If a patch is also newly set, the digital mixer 10 adds the transmission source and transmission destination data indicating the patch to the patch data in the current data, and if deleted, the transmission source indicating the deleted patch. And delete the destination data from the patch data. If it is necessary to change the operation mode of the plug-in in accordance with the change of these patches, or if the value of the signal processing parameter is changed, the digital mixer 10 changes the plug-in data corresponding to the corresponding plug-in. It is reflected in the insert / send return and parameter data.

If the current scene is changed, the digital mixer 10 immediately reflects the changed contents in the signal processing and signal transmission in the plug-in processing unit 30. That is, when a plug-in is added, a plug-in program part to be executed at each processing timing assigned to the plug-in is loaded into the DSP memory, and the program part is executed at each processing timing. To do. If a patch is set, the digital mixer 10 sets a necessary transmission path including writing and reading of a sound signal to and from the audio bus 23 so that signal transmission according to the setting is performed. In the case of deletion, on the contrary, the program part is deleted and the transmission path setting is canceled.
It is also possible to provide a mode in which changes in the current scene are not reflected in real time on signal processing and signal transmission. This mode can be used when creating a scene to be saved in scene data and used later.

One of the characteristic points of the digital mixer 10 described above is the operation in the case where a component that cannot be used in the digital mixer 10 is included in the scene read out to be used as the current scene. Therefore, this operation will be described below.
Note that a situation in which a component that cannot be used in the digital mixer 10 is included in the read scene is that scene data created and stored in another digital mixer that can use a component that cannot be used in the digital mixer 10 is stored in the digital mixer. This may occur when the data is read out at 10 and used as the current scene. The plug-in type that was available in the device that edited the scene data is not available in the digital mixer 10 due to the difference in firmware version.

First, FIG. 9 shows a display example of the scene operation screen.
A scene operation screen 300 shown in FIG. 9 is a screen for receiving an instruction to recall and save a scene included in the scene data. The scene operation screen 300 is a screen displayed on the display device 17 in accordance with a predetermined operation by the user.
The scene operation screen 300 includes a scene number selection unit 301, a store button 302, and a recall button 303.

Among these, the scene number selection unit 301 is an area for selecting a scene number (scene ID) to be operated, and the user can select a number by directly entering a number or by using an up / down button. it can.
The store button 302 is a button for instructing to save the contents of the current current scene as a scene having a number selected by the scene number selection unit 301. When this button is operated, the digital mixer 10 creates a scene by copying the contents of the current current scene, attaches the scene ID, and saves it in the scene data. If a scene with the same scene ID has already been saved, it is overwritten.

  The recall button 303 is a button for instructing to perform a recall for calling the scene of the number selected by the scene number selection unit 301 into the current scene. When this button is operated, the digital mixer 10 executes the process shown in FIG. 10, reads a scene having the corresponding scene ID, and overwrites and saves the current scene. However, the contents of the current scene may not be a complete copy of the saved scene. As described later, it may be replaced with the Unknown component, the recall safe function that rejects overwriting by the scene to be read for part of the current scene, or conversely, only part of the scene is selectively read and the current scene It is also possible to provide a focus recall function that is reflected on the screen.

  FIG. 10 shows a flowchart of the scene recall process executed by the CPU 11 of the digital mixer 10 in response to the operation of the recall button 303. Note that the processing according to the flowchart described below is performed by the CPU 11 executing a required program. However, in order to simplify the description, the digital mixer 10 will be described as executing the processing. In addition, the operation described as the operation of the digital mixer 10 in the above description is basically performed by the CPU 11 executing a required program.

  When detecting the operation of the recall button 303, the digital mixer 10 starts the process of FIG. 10 with the scene number #n selected at that time as an argument. In the process of FIG. 10, the recall safe function and the focus recall function are not considered in order to simplify the description.

  In the process of FIG. 10, the digital mixer 10 first clears the current scene, and cancels the settings of the loaded plug-in program parts and data transmission (S11). This is a process performed as a preparation stage for reading out a scene. If all are cleared at this point, signal processing will be interrupted even at locations where signal processing can be executed continuously before and after reading (eg, content that is common between the current scene and the scene to be read). Will occur. Therefore, it is also conceivable to select and clear only the part of the current scene whose contents are changed as the scene is read out.

After step S11, the digital mixer 10 repeats the processing of steps S12 to S15 with the plug-in data included in the scene #n to be read being sequentially processed.
In the process of the repetitive portion, the digital mixer 10 first determines whether or not the type ID of the plug-in data to be processed is included in the component data (S12). If this is Yes, the digital mixer 10 can use data for executing signal processing related to the plug-in indicated by the plug-in data to be processed, that is, the digital mixer 10 can use the plug-in. I understand.

  Therefore, in this case, the digital mixer 10 additionally copies the plug-in data to be processed to the current scene (S13). Further, the transmission source and transmission destination of the patch set for the plug-in data to be processed in the scene data of the scene #n are additionally copied to the patch data of the current scene (S14). As described above, the patch set for the plug-in data to be processed can be grasped by comparing the information on the transmission source or the transmission destination with the arrangement position of the plug-in indicated by the plug-in data. In step S13, the plug-in program part is not copied, but the digital mixer 10 can acquire the plug-in program part from the component data based on the type ID as necessary. It can also be considered that program parts are included.

  Further, in the case of No in step S12, it is understood that the plug-in indicated by the plug-in data to be processed cannot be used in the digital mixer 10 because necessary data cannot be acquired. In this case, the digital mixer 10 replaces the type ID of the plug-in data to be processed with the type ID of the Unknown component and adds it to the current scene (S15).

  This process means that only the type of plug-in to be placed is changed to an Unknown component while maintaining the location (assignment of processing resources) and also knowing the correspondence with the original plug-in by the plug-in ID. To do. Regarding the parameter data, the Unknown component does not use the parameters contained in it, so it may be deleted, but there is no particular problem if it is left.

  Further, after step S15, the digital mixer 10 executes step S14, and reflects the patch set for the plug-in data to be processed in the current scene as in the case of Yes in step S12. Therefore, the settings related to the original plug-in are maintained for the patch.

When the processing of the repetitive portion is completed for all plug-in data, the digital mixer 10 executes loading of plug-in program parts according to the current scene (S16). That is, the plug-in type is specified according to the type ID in each plug-in data, the plug-in program part for that type is obtained from the component data, and executed based on the information of the start slot and the final slot in the plug-in data. Each plug-in program component is written in the DSP memory in association with the processing timing.
At this time, the program component of the Unknown component may be written in the same program component with respect to the processing timings related to all slots from the start slot to the last slot. This is because the same processing may be repeatedly performed on the sound signal, whether through or cut.

Next, the digital mixer 10 executes data transmission setting according to the patch data in the current scene (S17). This setting does not change between the Unknown component and other components.
Up to step S17, the processing in FIG. 10 is completed, and the recall of scene #n can be executed by the above processing. The process of FIG. 10 is a process of a reading procedure. In this process, the CPU 11 functions as a reading unit.

  With the above processing, even if a plug-in that cannot be used in the digital mixer 10 is included in the scene to be recalled, it can be automatically replaced with the Unknown component and recalled. For this reason, it is possible to ensure that at least the plug-in processing unit 30 can execute signal processing according to the current scene after the recall.

  In addition, if the Unknown component has a function to pass through the sound signal, the patch of the scene to be recalled is maintained, so the sound signal is interrupted simply because there is no processing to be executed by the plug-in. There is nothing. On the other hand, when the Unknown component has a function of cutting the sound signal, the sound is interrupted at the place where the Unknown component is replaced. When the replaced plug-in is in the insert mode, no sound signal is output from the output destination channel, and even in the send / return mode, for example, there is no sound applied with the effect after processing by the plug-in. For this reason, the user can grasp | ascertain which part of the whole signal processing including the mixing process part 20 cannot be performed through the change of the sound output.

Next, FIG. 11 shows a display example of the plug-in arrangement screen 200 in the case where an Unknown component is arranged in the current scene along with the scene recall.
In the example of FIG. 11, two components are replaced with Unknown components, and their arrangement positions are displayed by Unknown icons 214. The arrangement position is the same as the position where the original plug-in was supposed to be arranged.
In addition, since the signal processing assumed at the time of creating the scene is not performed at the location of the Unknown icon 214, the Unknown icon 214 is highlighted in order to make the user surely recognize the existence and position of the Unknown icon 214. .

Note that by moving the cursor 211 to the position of the Unknown icon 214, the plug-in setting unit 240 can display the connection destination of the patch set for the corresponding Unknown component. As described above, the connection destination set for the plug-in before replacement is maintained as it is.
In the example of FIG. 11, no plug-in is selected in the plug-in selection unit 230. Correspondingly, “None” is displayed on the name display unit 232, and the size of the cursor 211 is one square. is there.
The user can also edit the plug-in arrangement screen 200 of FIG. 11 by deleting the Unknown component and replacing it with another available plug-in.

[Second Embodiment: FIG. 12]
Next, a second embodiment of the sound signal processing apparatus of the invention will be described.
The second embodiment differs from the first embodiment only in that the digital mixer 10 executes the process of FIG. 12 instead of the process of FIG.
For this reason, description of common parts will be omitted or simplified, and differences will be mainly described. Further, the same reference numerals as those in the first embodiment are used for portions that are the same as or correspond to those in the first embodiment. These points are the same in the following embodiments.

When detecting the operation of the recall button 303, the digital mixer 10 of the second embodiment starts the process of FIG. 12 with the scene number #n selected at that time as an argument.
The process of FIG. 12 is different from the process of FIG. 10 only in that the process of step S21 instead of step S14 is executed after step S15.
That is, in the process of FIG. 12, when the plug-in indicated by the plug-in data to be processed cannot be used, the digital mixer 10 sets the patch set for the plug-in data to be processed in the scene data of the scene #n to be recalled. Based on the data, patch data defining signal transmission from the input source of the signal to the plug-in to the output destination is added to the current scene.

  This transmission may be transmission via the plug-in processing unit 30. For example, it is conceivable to set a patch for transmitting a signal from an input source to an address corresponding to any processing timing assigned to an Unknown component, and a patch for transmitting a signal from the same address to an output destination.

  Also by the above, the same effect as the case where the Unknown component passes through the sound signal in the first embodiment can be obtained. In the second embodiment, since the Unknown component does not need to perform any signal processing including through, a program component corresponding to the Unknown component may not be prepared. However, in the second embodiment, the patch data itself relating to the plug-in that could not be used is not maintained in the current scene. Taking into consideration the pros and cons of these, it is advisable to decide whether to adopt the second embodiment.

[Third Embodiment: FIG. 13]
Next, a third embodiment of the sound signal processing apparatus of the invention will be described.
The third embodiment is different from the first embodiment in that the digital mixer 10 executes the process of FIG. 13 instead of the process of FIG. Correspondingly, component data having a function of passing through a sound signal (first unknown component information) and one having a function of cutting a sound signal (second unknown component information) Two types of Unknown component data are available.

Further, the process of FIG. 13 is different from the process of FIG. 10 only in that the process of steps S31 to S33 is executed when No in step S12.
That is, in the process of FIG. 13, when the plug-in indicated by the plug-in data to be processed cannot be used, the digital mixer 10 determines whether the operation mode included in the plug-in data to be processed is the insert mode (S31). ). If this is Yes, the digital mixer 10 replaces the type ID of the plug-in data to be processed with the type ID of the through Unknown component and adds it to the current scene (S32). If No, the type ID is replaced with that of the cut Unknown component and added to the current scene (S33). In either case, the process proceeds to step S14.

According to the above processing, when an unusable plug-in is in the insert mode, it can be replaced with a through-unknown component, and in other cases, for example, in a send-return mode, it can be replaced with a cut-unknown component.
In the insert mode, since the sound signal does not flow downstream unless the plug-in is passed through, it is desirable to perform through from the viewpoint of outputting the sound as much as possible without applying the desired effect. On the other hand, in the send / return mode, even if the cut is made without passing through, the so-called dry sound signal that does not pass through the plug-in flows downstream, and the so-called wet sound signal to which the effect is applied only disappears. Therefore, there is no need to return a signal from the plug-in processing unit 30 to the mixing processing unit 20 if no effect is applied. For this reason, there is no problem in cutting the signal.
As described above, according to the process of FIG. 13, an Unknown object suitable for the mode set in the plug-in can be automatically selected and arranged.

[Fourth Embodiment: FIG. 14]
Next, a fourth embodiment of the sound signal processing apparatus of the present invention will be described.
The fourth embodiment is different from the third embodiment only in that the digital mixer 10 executes the process of FIG. 14 instead of the process of FIG.
Further, the process of FIG. 14 is different from the process of FIG. 13 only in that the process of step SA is executed instead of step S31.

  That is, in the process of FIG. 14, the digital mixer 10 determines whether to use a through or cut component as an unknown component when the plug-in indicated by the plug-in data to be processed cannot be used. Replace the unavailable plug-in with an unknown component depending on the installation. This setting may be applied uniformly from what has been received from the user in advance, or may be applied by accepting settings relating to only that plug-in each time an unusable plug-in is discovered.

  According to the above processing, a plug-in that cannot be used is replaced with a through or cut Unknown component according to the user's preference, and the same effect as in the case of the first embodiment can be obtained.

[Fifth Embodiment: FIG. 15]
Next, a fifth embodiment of the sound signal processing apparatus of the invention will be described.
The fifth embodiment is different from the first embodiment only in that the digital mixer 10 executes the process of FIG. 15 instead of the process of FIG.
Further, the process of FIG. 15 is different from the process of FIG. 10 only in that the process of step SB is executed instead of step S15.

That is, in the process of FIG. 15, when the plug-in indicated by the plug-in data to be processed cannot be used, the digital mixer 10 substitutes the type ID of the plug-in data to be processed according to a preset rule. Replace with the type ID of the plug-in type and add to the current scene (SB).
For example, if the type of plug-in that cannot be used can be grasped to some extent by its name or the like, it may be possible to determine that a plug-in that has a slightly older version and generally has the same function can be used. In step SB, it is conceivable to select an alternative plug-in type according to such rules. It is also conceivable for the user to arbitrarily set an alternative plug-in type uniformly or for each plug-in type. Of course, alternative component types may include Unknown components. In addition, when an appropriate alternative plug-in cannot be determined according to a preset rule, it may be replaced with an Unknown component.

  According to the above processing, a scene can be recalled by replacing an unusable plug-in with another usable plug-in according to the user's preference.

[Modification]
This is the end of the description of the embodiment. However, the apparatus configuration, data configuration, screen display format and display content, component type, specific processing procedure, and the like are limited to those described in the above embodiment. Of course you can't.
For example, it is not essential that the hardware that performs signal processing is divided into a mixing processing unit 20 and a plug-in processing unit 30. Processing resources of the mixing processing unit 20 may be assigned to the components. Further, the processing resource to be allocated is not limited to the processing timing, and a register or a memory may be an allocation target. Further, the configuration of the plug-in processing unit 30 and the signal processing execution mode using the plug-in processing unit 30 are not limited to those described with reference to FIGS. 3 to 5.

In the above-described embodiment, the example in which the component to which DSP processing resources are allocated is a one-input, one-output plug-in component has been described. However, the present invention is not limited to this.
First, the component may be of multiple inputs and multiple outputs. However, it is assumed that the number of inputs and outputs is equal, and that the input signals are not mixed in the signal processing performed by the component. Such multi-input multi-output components can be replaced with through or cut unknown components without changing the patch and arrangement position, as in the case of the above-described embodiments.
Also, even if the number of inputs and outputs are different, or when all or part of each input signal is mixed in the signal processing performed by the component like a mixer, without changing the patch and the arrangement position, It is possible to replace it with a cut Unknown component.
The use of components is not limited to plug-ins.

  In the above-described embodiment, as an example of an Unknown component, a component having a through function and a component having a cut function have been described. However, an Unknown component having other functions may be used. An Unknown component that does not perform any processing may be used. The plug-in program part of the Unknown component that performs no processing is unnecessary, and there may be no program that should be executed at the processing timing assigned to the Unknown component that does not perform any processing. However, if the Unknown component does not perform any processing, it is conceivable that the sound data remaining in the DSP memory at the time of placement is continuously output to the patch destination on the output side. To avoid this, when assigning processing timing to an Unknown component that does not perform any processing, the output address corresponding to the last processing timing should be cleared.

  The functions of the digital mixer 10 described above can also be realized by causing a general-purpose computer to execute a required program. In this case, an input / output device for inputting / outputting sound signals and a signal processing expansion card provided with a DSP may be connected to the computer. Also, the functions of the digital mixer 10 can be distributed among a plurality of devices, and these can be cooperated to operate as a system having functions equivalent to the digital mixer 10.

In addition, the above program may be stored in a ROM or other nonvolatile storage medium (flash memory, EEPROM, etc.) provided in the computer from the beginning. However, it can also be provided by being recorded on an arbitrary nonvolatile recording medium such as a memory card, CD, DVD, or Blu-ray disc. By installing the program recorded in these recording media and executing the program on the computer, the computer can execute necessary processing.
Furthermore, it is also possible to download from an external device that is connected to a network and includes a recording medium that records the program, or an external device that stores the program in a storage unit, and install and execute the program on a computer.

In addition to the digital mixer, the present invention allocates processor processing resources to virtual signal processing components such as plug-ins, and uses the allocated processing resources to execute signal processing for each component. It can be applied to the sound signal processing apparatus. For example, it can be applied to microphones, effectors, recorders, amplifiers, speakers, synthesizers, and the like.
In addition, the configurations and modifications described above can be applied in appropriate combinations within a consistent range. Conversely, it is not necessary to implement all the configurations included in the above-described embodiments at the same time.

  As is apparent from the above description, according to the present invention, it is possible to improve the convenience of the arrangement data indicating the allocation of the processing resources of the processor to the components in the sound signal processing device. In addition, through this, the operability of the sound signal processing apparatus can be improved.
