Furthermore, the parameters that can be assigned are limited to the range registered in the list,
and registering a large number of parameters in the list to increase the choice makes it more
difficult to select the parameter that you want to assign quickly from among them. There was a
problem of becoming

[0027]
A characteristic point of the mixer 10 having the above configuration is a function of assigning a
parameter for editing a value using an encoder to an encoder included in a ch strip provided on
the operation panel. Therefore, this point will be described in detail below. First, FIG. 2 shows a
schematic configuration of an operation panel of the mixer 10. FIG. 2 shows only the components
related to the above-described function of assigning parameters to the encoder.
[0028]
As shown in FIG. 2, the operation panel 100 of the mixer 10 includes a plurality of channel strips
110, encoder selection keys 131 and 132, assignment content indicators 133 and 134,
assignment switching keys 135 and 136, a common encoder 140 and a display 150. , A screen
selection key group 170 and a layer selection key group 180 are provided.
[0029]
Among them, the ch strip 110 is an operator group in which operators associated with any signal
processing ch in the DSP 18 and operators for receiving editing operations of parameter values
used for the signal processing of the ch are collected.
In the example of FIG. 2, 16 channel strips 110 are provided in the input channel section 121,
and 8 channel strips 110 are provided in the output channel section 122.
[0030]
Then, by operating the keys of the layer selection key group 180, signal processing chs in the
DSP 18 can be assigned to these ch strips 110. For example, any one of the 16th, 17th to 32nd,
and 33rd to 48th layers of the 48 input channels are assigned to the 16 channel strips 110 of
the input channel section 121, and one of the 24 output channels is allocated. The layers of the
eighth, ninth to sixteenth, and seventeenth to twenty-fourth layers are respectively assigned to
the eight channel strips 110 of the output channel section 122. In the input channel section 121
and the output channel section 122, layers can be allocated independently.
10-04-2019
9
[0031]
Each channel strip 110 has two channel encoders 111 and 112, an SEL key 113, an ON key 114,
and a fader 115. Among them, as shown in FIG. 3, each of the ch encoders 111 and 112 has a
knob A as an operation unit, and is an encoder that can perform two operations of rotation
operation in the arrow X direction and pressing operation in the arrow Y direction. . Then, as
described later, parameters of arbitrary items are independently assigned to the channel
encoders 111 and 112, respectively, and are used as operators for setting parameter values of
the assigned items of the channel corresponding to the channel strip 110. be able to. The
configuration in which the pressing operation is also possible is to enable operation without
discomfort even when a parameter that accepts on / off setting with a key on the panel is
assigned.
[0032]
The SEL key 113 is an operation element for receiving selection of a channel corresponding to
the channel strip 110. When the SEL key 113 is pressed, the CPU 11 selects a ch corresponding
to the ch strip 110 to which the SEL key 113 belongs, and causes the display 150 to display a
screen regarding the setting of the parameter of the ch. The ON key 114 is an operation element
for receiving the setting of output on / off of ch. The fader 115 is an encoder that detects the
amount of movement of the knob, and is an operation element for receiving the setting of the
output level of the ch.
[0033]
Next, encoder selection keys 131 and 132 are keys provided in association with the ch encoders
111 and 112, respectively, and are operators for selecting a corresponding ch encoder as a
parameter assignment destination. The assignment content indicators 133 and 134 are small
LCD displays provided in association with the channel encoders 111 and 112, respectively, and
are displays for displaying which item of parameter is assigned to the corresponding channel
encoder. It is a means. The assignment switching keys 135 and 136 are operators for switching
the assignment contents according to the list when assigning parameters to the ch encoders 111
and 112 using an assignment list described later.
[0034]
10-04-2019
10
Further, the common encoder 140 is an encoder provided separately from the ch strip 110, and,
like the ch encoders 111 and 112, has a configuration that allows a rotation operation and a
pressing operation. Then, as described later, regardless of the correspondence between the
channel strip 110 and the signal processing channel, any parameter of any channel can be
assigned and used as an operator for setting the value of that parameter .
[0035]
Next, the display 150 is an LCD, and can display various GUI screens in accordance with an
instruction from the CPU 11. In the example of FIG. 2, as a screen related to the parameter
assignment function described here, a GUI screen 160 on which an image of an operator
corresponding to the parameter for the signal processing ch selected according to the pressing of
the SEL key 113 is arranged. It shows.
[0036]
The GUI screen 160 is a screen relating to the first input channel, and, of these, for example, the
operating element 161 indicates an operating element for setting the value of the compressor
gain parameter. An operator 162 indicates an operator for setting a pan parameter value.
Further, the images of the operators 161 and 162 also function as display units for displaying
the current values of the corresponding parameters by the marks 161a and 162a.
[0037]
Then, by pressing the encoder selection key 131 or 132 and touching the portion corresponding
to the image of any operator on the GUI screen 160, the user selects the encoder corresponding
to the operator and pressed the parameter. It can be assigned to the channel encoders 111 or
112 of each channel strip 110 corresponding to the key. In this case, which parameter of the
signal processing channel is assigned to which channel strip of the channel encoder 110 follows
the correspondence between the channel strip 110 and the signal processing channel defined by
the layer as described above.
10-04-2019
11
[0038]
In the example of FIG. 2, the parameter of the gain of the compressor corresponding to the
operation element 161 is assigned to the ch encoder 111, and the assignment content display
133 displays "Cp. Gain" to that effect. Similarly, the pan parameter corresponding to the
operation element 162 is assigned to the ch encoder 112, and the assignment content display
134 displays “Pan” to that effect.
[0039]
Further, the user can assign the parameter corresponding to the operator to the common
encoder 140 by touching the portion corresponding to the image of any operator on the GUI
screen 160 without pressing the encoder selection key. Can. In this case, assignment of ch also
follows the contents of the GUI screen. That is, when the operator 161 is touched in the state of
FIG. 2, the parameter of the gain of the compressor regarding the first input channel displayed
on the GUI screen 160 is allocated to the common encoder 140.
[0040]
Note that since the parameters that can be set in each signal processing channel are diverse, it is
difficult to arrange the images of the operators corresponding to all the parameters in one
screen. Therefore, in the mixer 10, the operators are designed together for each related
parameter to design the screen, and the keys of the screen selection key group 170 can be used
to select which GUI screen including the operators to be displayed on the display 150. ing.
[0041]
As can be seen from the above, in the mixer 10, while pressing the encoder selection key 131 or
132, the parameters of the ch encoders 111 and 112 are simply touched by touching the image
of the operation element corresponding to the desired parameter on the GUI screen 160. Since it
is possible to assign, it is possible to perform assignment of parameters of a wide choice with
very simple operation.
[0042]
10-04-2019
12
However, since this assignment is uniformly performed on all the channel strips 110 to be
assigned, the parameters to be assigned are common to all signal processing channels
corresponding to the channel strip 110 to be assigned. It is only parameter.
For example, when both the input channel section 121 and the output channel section 122 are to
be assigned at one time, send level parameters to the AUX bus which are present in the input
channel but not present in the output channel are assigned. It is excluded from the subject of
However, in the case where only the input channel section 121 is to be assigned, send level
parameters to the AUX bus that exist in common for all the input channels can be assigned.
[0043]
Next, assignment of parameters to the channel encoders 111 and 112 described above and
processing executed by the CPU 11 to realize functions associated therewith will be described.
First, FIG. 4 shows a flowchart of processing executed by the CPU 11 when a touch operation is
performed on the position of any operator on the GUI screen 160. The CPU 11 starts the process
shown in the flowchart of FIG. 4 when a touch operation to the position of any one of the
operators on the GUI screen 160 is detected by the touch sensor stacked on the display 150.
[0044]
Then, first, the item of the parameter corresponding to the touched operator is specified (S11).
The item of the parameter indicates an identifier for specifying the parameter other than the
identifier of the signal processing ch to which the parameter belongs. In addition, information
necessary for this identification can be included in the screen data of the GUI screen 160 being
displayed.
[0045]
Next, the CPU 11 determines whether any one of the encoder selection keys is being pressed at
the time of operation detection (S12). When the key is being pressed, the process proceeds to
step S13 and subsequent steps in order to assign a parameter to the ch encoder corresponding to
the key. When a plurality of encoder selection keys are being pressed, it is treated that pressing
10-04-2019
13
is effective only for one encoder selection key selected according to some rule such as first-comefirst-order priority.
[0046]
Then, it is determined whether or not the parameter specified in step S11 is common to all the
channels corresponding to the channel strip 110 in the allocation range (for example, the input
channel section 121 and the output channel section 122) ( S13). As information used for this
determination, for each parameter item, information on the range (signal processing ch) in which
the parameter exists may be stored in the mixer 10 as a table.
[0047]
In the case of YES at step S13, the CPU 11 next causes the display to display an assignment
confirmation dialog 210 shown in FIG. The assignment confirmation dialog 210 is a GUI screen
for accepting selection of whether or not parameters may be assigned to the ch encoder as
instructed by the user, and selection of whether the assignment is performed directly or using a
list. is there. As options for this, an OK button 211 indicating direct assignment, a cancel button
212 indicating assignment cancellation, and a list registration button 213 indicating assignment
using a list are prepared.
[0048]
In step S15, the CPU 11 determines the user's instruction in accordance with which of these
buttons is pressed. Then, if the instruction is direct assignment, the channel corresponding to the
channel strip 110 is associated with the channel encoder corresponding to the pressed encoder
selection key 131 or 132 of each channel strip 110 in the range to be assigned. , Assign the
parameters of the item identified in step S11 (S16). Thereafter, the display of the assignment
content indicator 133 or 134 is updated according to the change of the assignment content
(S17), and the process is ended.
[0049]
10-04-2019
14
If NO in step S13 or an instruction to cancel is given in step S15, no assignment is performed,
and the process ends. If the instruction is assignment using a list in step S15, the CPU 11 next
causes the display to display the list registration dialog 220 shown in FIG. 6 as a pop-up, and
accepts the user's instruction (S18).
[0050]
In the list registration dialog 220, whether the item of the parameter specified in step S11 may
be registered in the assignment list or whether the assignment is also performed simultaneously
with the registration for the ch encoder corresponding to the pressed encoder selection key It is
a GUI screen for receiving a selection. As options for this, an OK button 223 indicating only
registration in the list, a cancel button 224 indicating cancellation of registration, and an
assignment button 225 indicating that assignment is also performed simultaneously with
registration are prepared.
[0051]
Note that the assignment list is a list in which, for each row of the ch encoder (unit for assigning
a parameter of one item), candidate items of parameters to be assigned to the ch encoder of the
row are registered in advance. It is displayed on the list display unit 221. The cursor 222
indicates the position where the addition is made when adding a new parameter item to the
assignment list. Then, by pressing the encoder selection key while operating the assignment
switching keys 135 and 136 shown in FIG. 2, items of parameters to be assigned to the ch
encoder can be switched in the order of the list or in the reverse order.
[0052]
Next, in step S19, the CPU 11 determines the user's instruction according to which button of the
list registration dialog 220 is pressed. Then, if the instruction is only registration or assignment,
first, the item of the parameter specified in step S11 is additionally registered in the assignment
list of the ch encoder corresponding to the pressed encoder selection key (S20). This registration
may be performed at the end of the list while leaving the original registration content. If the
instruction content in the list registration dialog 220 is only registration, the process ends as
above (S21). In this case, the assignment of parameters to the ch encoder does not change.
10-04-2019
15
[0053]
On the other hand, if the instruction content is to perform the assignment, the process proceeds
to step S22. Then, in the assignment list corresponding to the pressed encoder selection key, the
item of the parameter specified in step S11, that is, the item registered in step S20 is selected
(S22). Thereafter, the process proceeds to step S16, the parameters of the item in the selected
state are assigned to the ch encoder, and the display of the assignment content display is
updated according to the change of the assignment content (S17).
[0054]
By these processes, assignment of parameters to the ch encoder 111 or 112 or registration of
parameter items in the assignment list of parameters according to the touch operation on the GUI
screen 160 and the pressing operation on the encoder selection key 131 or 132 is performed. it
can.
[0055]
On the other hand, when the encoder selection key is not pressed in step S12, the CPU 11
interprets that the touch operation on the GUI screen 160 is the assignment operation of the
parameter to the common encoder 140.
Then, the parameter of the item specified in step S11 of the ch corresponding to the GUI screen
160 being displayed on the display 150, that is, the parameter corresponding to the operator
touched on the GUI screen 160 is assigned to the common encoder 140 S23). In this case, since
it is not necessary to change the display of the assignment content indicator, the process ends. By
the above processing, parameter assignment to the common encoder 140 can be performed
according to the touch operation on the GUI screen 160.
[0056]
Next, FIG. 7 shows a flowchart of processing when the assignment switching key 135 or 136 is
operated. When detecting the pressing operation of the assignment switching key 135 or 136,
the CPU 11 starts the processing shown in the flowchart of FIG.
10-04-2019
16
[0057]
Then, first, it is determined whether or not any encoder selection key is being pressed at the time
of operation detection (S31). When the key is being pressed, the process proceeds to step S32 to
update the assignment of the parameter to the ch encoder corresponding to the key using the
assignment list described using FIG. When a plurality of encoder selection keys are being
pressed, it is treated that pressing is effective only for one key selected according to some rule
such as first-come-first-order priority.
[0058]
Then, in the assignment list corresponding to the pressed encoder selection key, in response to
the operation of assignment switching key 135 or 136, the item of the parameter registered
before or next to the currently selected item is selected. It is put in a state (S32). Then, in the
channel encoder corresponding to the pressed encoder selection key 131 or 132 of each channel
strip 110 in the range to which allocation is performed, the channel associated with the channel
strip 110 is selected in step S 32. Assign the parameters of the item (S33). Thereafter, the display
of the assignment content indicator 133 or 134 is updated according to the change of
assignment (S34), and the process is ended.
[0059]
On the other hand, when the encoder selection key is not pressed in step S31, it is assumed that
no ch encoder is selected, and the processing is ended without changing the assignment.
According to the above processing, in accordance with the pressing operation on the assignment
switching key 135 or 136 and the encoder selection key 131 or 132, the assignment contents of
the parameters to the ch encoder 111 or 112 can be updated according to the assignment list.
[0060]
If such a function is provided, the type of the GUI screen 160 is changed or the screen
corresponds to the desired parameter from the screen by registering items to be allocated to the
ch encoder relatively frequently in the allocation list. Since the parameter assignment can be
performed by a simple operation without searching for a manipulator, higher operability can be

17
obtained.
[0061]
Next, FIG. 8 shows a flowchart of processing when one of the ch encoders 111 and 112 and the
common encoder 140 is operated.
When the CPU 11 detects the operation of the channel encoders 111 and 112 or the common
encoder 140 of any channel strip 110, the CPU 11 starts the processing shown in the flowchart
of FIG.
[0062]
Then, when the operated encoder has a parameter assignment (YES in S41), the value of the
parameter assigned to the encoder is changed according to the operation content of the encoder
(rotation count number or pressing / releasing) (S42), and the process ends. If the assignment is
not made, a warning to that effect is displayed on the display 150 (S43), and the process is
ended.
[0063]
At the time of starting the mixer 10, etc., allocation may not be made yet. Alternatively, even
when the operation of releasing the assignment is performed, the state is returned to the nonassigned state. In such a state, since the operation of the encoder has no meaning, the user is
warned by the above processing to prevent useless operation.
[0064]
Next, with reference to FIG. 9, an operation of saving and calling a scene in the mixer 10 will be
described. In the mixer 10, in addition to the values of various parameters used by the DSP 18
for signal processing, at least the assignment contents of the parameters to the ch encoders 111
and 112 are stored in the current memory. In addition to this, the contents of the assignment list
10-04-2019
18
and the contents of assignment to the common encoder 140 may be stored.
[0065]
Then, when the contents of the current memory are stored as a scene in the scene memory, these
assigned contents are also stored together with the values of the parameters. Then, when the
scene is recalled (recalled), the information of the stored assignment content is also read out to
the current memory, and is reflected in the parameter assignment to each encoder.
[0066]
Since it is considered that assignment of parameters to the encoder is often determined
according to the usage scene of the mixer 10, it is stored again together with values of
parameters closely related to the usage scene, and can be recalled again. It becomes possible to
perform assignment in accordance with the usage scene without the time and effort of
assignment operation, and the time and effort of operation can be reduced. Of course, the user
may be able to set whether or not to recall the assignment contents at the time of scene recall.
[0067]
This is the end of the description of the embodiment, but it goes without saying that the
configuration of the apparatus, the specific processing content, the display content of the screen,
the configuration of the operation panel, the operation method and the like are not limited to
those described in the above embodiment. It is. For example, in the embodiment described above,
an example in which an encoder selection key corresponding to each row of the ch encoder is
provided has been described, but one encoder selection key may be provided for a plurality of
rows. In this case, before assigning a parameter to a channel encoder or registering a parameter
item in an assignment list, which row of channel encoders among the channel encoders
corresponding to the pressed encoder selection key should be assigned or registered. Selection
may be accepted, and assignment and registration may be performed for the selected target.

FIG. 10 shows an example of an encoder selection dialog for this reception. The encoder selection
dialog 230 shown in this figure is provided with an encoder selection button 231 for selecting
the ch encoder 111 and an encoder selection button 232 for selecting the ch encoder 112.
Further, in the example of the figure, the faders 115 which are also different in shape from the
ch encoders 111 and 112 but are also encoders can be selected as the assignment destinations,
and a fader selection button 233 for selecting them is also provided.
[0069]
Then, after the target of assignment or registration is selected by these buttons, the selection can
be confirmed by pressing the OK button 234. When the cancel button 235 is pressed, allocation
or registration is canceled. In the above embodiment, the assignment table described with
reference to FIG. 6 is provided for each row of the ch encoder. However, a common assignment
table may be provided for a plurality of rows. In this case, parameters of items registered at
adjacent positions on the assignment table may be assigned to the ch encoders in adjacent rows.
For example, in the case where the contents of the table are as shown in FIG. 6, when assigning
“Aux 5” to the ch encoder 111, “Pan” is assigned to the ch encoder 112 or the like.
[0070]
In addition, when the assignment switching key is operated in this situation, it is possible to shift
the selection items one by one and change the assignment like scrolling in line units, and the
number of lines using a common assignment table. It is also conceivable to change the allocation
like page switching by shifting by minutes. Further, the operator may be selected on the GUI
screen 160 not by touching the screen but by using a pointing device by clicking a mouse or the
like.
[0071]
Also, instead of using common encoder selection keys 131 and 132 and assignment switching
keys 135 and 136 for all the channel strips 110, separate channel channel sections for each
channel, for example, for the input channel section 121 and the output channel section 122,
respectively. Encoder selection keys and assignment switching keys may be provided so that
parameters can be assigned to ch encoders independently for each section. Also, the shape and
number of the ch encoders are of course not limited to those of the above-described embodiment.

Further, each function described in the above embodiment can receive an operation by an
operation element provided on the main body of the mixer 10 and can perform display using a
display, as well as using the remote controller such as a physical controller. The present
invention is also applicable to the case of editing parameter values used by the DSP 18. In this
case, for example, the mixer 10 stores programs and data necessary for screen display and
parameter setting instructions, and provides those data to the remote controller in response to a
request from the remote controller. The screen may be displayed on the display and the
operation may be accepted.
[0073]
Furthermore, even if each function described in the above embodiment is other than a mixer, any
acoustic signal processing means for processing acoustic signals in a plurality of signal
processing channels, provided in a synthesizer, sequencer, recorder with editing function, etc.
The present invention is applicable to an apparatus for editing the value of a parameter used for
processing an acoustic signal.
[0074]
Further, the program of the present invention is a program for causing a computer to control
required hardware to function as an acoustic control device to realize the functions as described
above, and in addition to being stored in advance in a ROM, HDD, etc. , A non-volatile recording
medium (memory) such as a CD-ROM or a flexible disk, and the program is read from the
memory to the RAM and executed by the CPU, or an external device provided with a recording
medium storing the program The same effect can be obtained even if the device or program is
downloaded from an external device stored in storage means such as an HDD and executed.
In addition, the configurations and modifications described above can be combined appropriately
and applied as long as no contradiction arises.

As apparent from the above description, according to the acoustic control device, the acoustic
signal processing device, and the program of the present invention, the acoustic signal
processing means for processing acoustic signals in a plurality of signal processing channels uses
the parameters used for processing the acoustic signals. When editing values, encoders provided
on channel strips can be used more efficiently. Therefore, by applying the present invention, the
operability of the acoustic control device can be improved.
