110, input ch 120-1 to 128, mixing bus 130, output ch 140-1 to 96, matrix bus 150, matrix
output ch 160-1 to 8, cue bus 170, a cue output ch 180, and an output patch 190.
[0021]
Then, in the DSP 18, the input patch 110 has 128 input channels 120-1 to 120-128 (when there
is no need to specify an individual, a code without "-" or later is used. The same applies to other
codes. Can be patched (connected) to any of the input ports of the analog input unit and the
digital input unit prepared to correspond to the input terminals of the waveform I / O 17,
respectively.
[0022]
At each input channel 120, as shown in FIG. 3, after the signal processing element of the
attenuator 121, the equalizer 122, and the fader 123 performs signal processing on the signal
input from the patched input port, there are 96 channels of mixing The processed signal is
output to any one of the buses 130. Of course, other signal processing elements may be
provided. In FIG. 2, for convenience of illustration, the output from input channel 120 to each
system of mixing bus 130 is shown by one line, but for this output, the on / off setting and the
setting for each combination of input channel 120 and mixing bus 130 It is possible to make
level adjustments. The outputs to the matrix bus 150 and the queue bus 170 will be described
later.
11-04-2019
7
[0023]
Next, in the mixing bus 130, the signals input from the input channels 120 are mixed and output
to the output channels 140 provided corresponding to the mixing buses 130 and 96 channels
from 140-1 to 140-96. Then, in each output channel 140, signal processing is performed on the
signal input from the corresponding mixing bus 130 using an equalizer, a compressor, a fader, or
the like, as in the case of the input channel 120. However, the type and the order of the signal
processing elements may not be the same as the input channel 120.
[0024]
Next, the matrix bus 150 is provided with eight systems, and signals of ch arbitrarily selected
from the input ch120-1 to 128 and the output ch140-1 to 96 can be input and mixed. Therefore,
each input ch 120 and each output ch 140 also perform signal output to each matrix bus 150.
This output can perform on / off setting and level adjustment for each combination of each of the
channels 120 and 140 and the matrix bus 150.
[0025]
The signals mixed by the matrix bus 150 are output to matrix output channels 160 provided for
eight channels 160-1 to 160-8 corresponding to the respective systems of the matrix bus 150.
Then, on each matrix output channel 160, the same signal processing as that for the output
channel 140 is performed on the signal input from the corresponding matrix bus 150 by an
equalizer, a compressor, and the like.
[0026]
The seventh seventh matrix bus 150-7 and the eighth matrix bus 150-8 of the matrix bus 150
can output signals from the first to sixth matrix output channels 160-1 to 160-6. . Each of these
outputs can also perform on / off setting and level adjustment separately. This output is provided
to use the seventh matrix bus 150-7 and the eighth matrix bus 150-8 as the second queue bus,
which will be described later.
11-04-2019
8
[0027]
Next, the cue bus 170 is a stereo bus having two systems of LR, and is a bus for generating a
signal for monitoring. For this reason, each input ch 120, each output ch 140, and each matrix
output ch 160 are provided with a signal output path to the queue bus 170, so that on / off
setting and level adjustment of those signal outputs can be performed individually. The signal
mixed by the cue bus 170 is output to the cue output ch 180. Then, on the queue output channel
180, simple signal processing such as level adjustment is performed. Since the cue bus 170 is
provided to monitor the signal being processed in each channel, it is not necessary to add various
signal processing as in the output channel 140 to the monitor signal generated here. It is.
However, the same signal processing as that of the output ch 140 can be performed without
hindrance.
[0028]
Further, the outputs of the output ch 140, the matrix output ch 160, and the queue output ch
180 are supplied to the output patch 190. Then, these various output channels are patched by
the output patch 190 to the output ports of the analog output unit and digital output unit
prepared to correspond to the output terminals in the waveform I / O 17, and the signal after
processing by the output channels To the patch destination output port and output from there.
[0029]
The cue output channel 180 may be fixedly patched to a predetermined monitor output terminal
or may be output without passing through an output patch. Signal processing by these units
provided in the DSP 18 is controlled based on the current setting values (current data) of each
parameter stored in the memory. The values of these parameters can be adjusted for each of the
ch and other signal processing elements by the controls on the operation panel 200. Also, the
function of each unit may be realized by software or hardware.
[0030]
By providing the cue bus 170 and the cue output ch 180 in the sound signal processing
11-04-2019
9
apparatus 10, the operator can arbitrarily select any signal without affecting the signals output
from the input ch 120, the output ch 140 and the matrix output ch 160 to the bus or the output
patch 190. The signal of ch can be monitored. A method of selecting a channel to be monitored
and which signal position in the channel is to be monitored will be described later.
[0031]
Next, FIG. 4 shows a schematic configuration of an operation panel of the sound signal
processing apparatus 10. As shown in FIG. As shown in FIG. 4, the operation panel 200 of the
sound signal processing apparatus 10 includes a ch strip unit 201, a display 230, a rotary
encoder 240, and a switch group 250. The ch strip unit 201 is provided with 16 ch strips 210,
and signal processing ch such as input ch 120, output ch 140, matrix output ch 160 is assigned
to each ch strip 210 using a layer etc. Each operator included in can be used as an operator for
performing an operation related to the assigned ch. It is also possible to assign a ch group such
as a DCA group.
[0032]
Each channel strip 210 also includes a rotary encoder 211, a cue key 212, a selection key 213,
an on key 214, and a fader 215. Among them, the rotary encoder 211 is a manipulator used to
assign a parameter included in ch and adjust the value of the assigned parameter. The queue key
212 is a queue operator for instructing a channel to be monitored (output a signal from the
channel to the queue bus 170). As a method of selecting a ch to be monitored according to the
operation of the cue key 212, various methods such as on / off switching with toggle for each ch,
late arrival priority, and the like can be considered. This point will be described later.
[0033]
The selection key 213 is an operator for selecting a channel. The on key 214 is an operator for
toggle adjustment of a parameter that determines on / off of the sound signal transmission from
the ch. The fader 215 is an operation element for adjusting the value of the fader parameter of
ch by the operation of the knob 215a.
[0034]
11-04-2019
10
Next, the display 230 displays a GUI (Graphical User Interface) screen, receives various
operations including setting of parameter values, assignment of parameters to operators, etc.,
and an operation state of the sound signal processing apparatus 10 or They are display means
and operation means for displaying the value of the parameter currently set. The display 230 can
also display the state of settings relating to the monitor (queue function) and a screen for
receiving the settings.
[0035]
The rotary encoder 240 is an operator that can assign any parameter, including those described
above, and use that parameter for adjustment. The switch group 250 is a place where switches
having various functions including selection of layers are arranged.
[0036]
Next, FIG. 5 shows an example of an operation screen displayed on the external controller 30. In
the external controller 30, a GUI screen for receiving an operation on the sound signal
processing apparatus 10 is displayed on the display 300, and the user can operate the GUI
screen to perform an operation on the sound signal processing apparatus 10. .
[0037]
FIG. 5 shows an example of a screen for receiving an operation for each channel. In the screen of
FIG. 5, the ch strip unit 201 is displayed on the display 300, and the detailed display unit 203
corresponding to the display 230 of FIG. 4 is also displayed. Also on this screen, channels are
allocated to each channel strip 210 of the channel strip section 201 in the same manner as in the
case of the operation panel 200, and each channel strip 210 is used as an operation unit for
performing operations regarding the assigned channels. it can. This operation includes an
instruction to set the assigned ch as a target of monitoring by the operation of the queue
operator.
[0038]
11-04-2019
11
A characteristic point of the above-described sound signal processing apparatus 10 is that buses
other than the queue bus 170 can be temporarily used as an additional queue bus. Hereinafter,
this point will be described in detail. In this embodiment, although an example in which the
seventh matrix bus 150-7 and the eighth matrix bus 150-8 are used as an additional (second)
queue bus will be described, a bus which can be an additional queue bus is It is not restricted to
this.
[0039]
In the sound signal processing apparatus 10, the seventh matrix bus 150-7 and the eighth matrix
bus 150-8 can be operated as matrix buses for realizing the function of the matrix mixer
(generally, the first mode). Mode operation). In addition to this, it is possible to switch to
operation as a stereo cue bus for adding a system of monitor output (operation in cue mode
which is the second mode) according to the user's operation.
[0040]
FIG. 6 and FIG. 7 show screens for accepting this switching operation and the setting regarding
the queue function. FIG. 6 shows an example where the seventh matrix bus 150-7 and the eighth
matrix bus 150-8 are in the normal mode (additional queue bus disabled), and the case shown in
FIG. 7 is the queue mode. Example (additional queue bus enabled). The queue setting screen 400
shown in FIG. 6 and FIG. 7 is a GUI screen displayed on the display 230 of the operation panel
200 or the display 300 of the external controller 30 for receiving settings relating to a queue
function.
[0041]
In the queue setting screen 400, a queue addition setting button 401 is provided, and the user
operates the button to set the seventh matrix bus 150-7 and the eighth matrix bus 150-8 in the
normal mode. The cue mode can be toggled. Further, as the selection method setting button 402,
an operation element for selecting a method of selecting a ch to be monitored from "MIX CUE"
and "LAST CUE" is also provided. "MIX CUE" is a mode in which monitoring on / off is switched
by toggle for each channel, and when a plurality of channels are turned on, the outputs of those
11-04-2019
12
channels are mixed to form a monitoring signal. “LAST CUE” is a mode in which the
monitoring target is selected with late arrival priority and the output of at most one ch is a
monitoring signal.
[0042]
Further, the output selection unit 403 is provided with an operation element for selecting from
which position of a channel to be monitored the signal to be monitored is to be monitored (is to
be output to the queue bus). The output selection unit 403 can select either “PFL” indicating
the front of the fader or “AFL” indicating the rear of the fader 123, and the output position of
the signal corresponding to each option is, for example, shown in FIG. As shown. If "PFL" is
selected, the signal before level adjustment can be monitored on the monitoring target channel,
and even if the signal level of the corresponding channel is narrowed by the fader 123, the signal
processed on the corresponding channel is confirmed it can. When "AFL" is selected, it is possible
to confirm the signal actually supplied to the mixing and output from the monitoring target
channel.
[0043]
Further, in a state where the queue mode is selected by the queue addition setting button 401, as
shown in FIG. 7, the queue B setting unit 410 is prepared on the queue setting screen 400, and
setting regarding additional queue bus is performed here. Can. Items that can be set by the queue
B setting unit 410 are substantially the same as items that can be set on the queue setting screen
400 in the normal mode. However, if the queue function by the additional queue bus is different
from the queue function by the fixed queue bus 170, the items that can be set are also different
accordingly.
[0044]
In the examples of FIGS. 6 and 7, the setting of bypass by the bypass setting button 414 can be
given as an example of the difference between the queue function by the additional queue bus
and the queue function by the fixed queue bus 170. Here, the output of the matrix bus 150 is
supplied to the output patch 190 via the matrix output ch 160, and more versatile signal
processing is possible than the output of the queue bus 170 passing through the queue output
ch 180. The above-mentioned bypass can invalidate the signal processing function which is not
11-04-2019
13
in queue output ch 180 among matrix output ch 160, and can output it through the same signal
processing as the case where the signal for monitoring mixed with matrix bus 150 is mixed by
cue bus 170 It is a function to If it is desired to output monitor signals after performing various
signal processing using the function of the matrix output channel 160, the bypass may be turned
off.
[0045]
The selection method setting button 412 is also prepared on the side of the queue B setting unit
410, and the selection method of the ch to be monitored can be set independently for the fixed
queue bus 170 and the additional queue bus. However, it is also possible to link these settings,
and the mode link setting button 413 allows the link to be switched on / off. The settings made
on these screens are stored in the flash memory 12 or the RAM 13 by the CPU 11.
[0046]
Next, setting of the queue output destination will be described. In the sound signal processing
apparatus 10, when the additional queue bus is enabled for each channel to be monitored, such
as the input channel 120, the output channel 140, and the matrix output channel 160, the signal
of the channel is fixed to the fixed queue bus. It is possible to set which of (A) and the additional
queue bus (B) to use for monitoring. This setting is a setting that works when the corresponding
channel is selected as a target of monitoring. Although there may be cases other than ch, such as
DCA group, that can be selected as targets of monitoring, for the sake of simplicity, here, for
convenience, all items that can be selected as targets of monitoring are referred to by the word
"ch". It shall represent.
[0047]
FIG. 8 shows an example of a screen for this setting. FIG. 8 shows a queue output setting screen
500 for receiving the setting of the queue output destination for the first input channel 120-1.
This screen is provided with a queue A selection button 501 for switching on / off of output to a
fixed queue bus, and a queue B selection button 502 for switching on / off of output to an
additional queue bus. Both buttons can be toggled on and off, but they can not be turned off
simultaneously.
11-04-2019
14
[0048]
That is, as the queue output destination, three types can be set: only a fixed queue bus (A), only
an additional queue bus (B), and both (A + B). When the setting operation of the output
destination is performed on the queue output setting screen 500, the CPU 11 executes the
processing of FIG. 9 to set the queue output destination for each channel (S1). The process of FIG.
9 is a process of the first setting procedure.
[0049]
Next, processing executed by the CPU 11 to perform control regarding an additional queue bus
will be described. First, FIG. 10 shows a flowchart of processing when the operation of the queue
addition setting button shown in FIG. 6 and FIG. 7 is detected. The process of accepting the
operation of the queue addition setting button is the process of the reception procedure, and the
process of FIG. 10 is the process of the switching procedure for enabling or disabling the
additional queue bus.
[0050]
When detecting the operation of the queue addition setting button 401, the CPU 11 starts the
process shown in the flowchart of FIG. In this process, first, the CPU 11 toggles the mode of the
seventh and eighth matrix buses 150-7 and 8 with the normal mode and the queue mode (S11).
Then, after step S12, processing according to the mode after switching is performed.
[0051]
When the mode after switching is the queue mode, the CPU 11 turns on the operated queue
addition setting button 401 (S13) and displays the queue B setting unit 410 on the queue setting
screen 400 (S14). Then, the transmission setting from each channel to the seventh and eighth
matrix buses 150-7 and 8 in the normal mode is saved in a predetermined storage area of the
memory (S15). This transmission setting is for current signal processing of parameters such as
signal transmission on / off and transmission level from each ch to these buses when the seventh
and eighth matrix buses 150-7 and 8 are used as matrix buses. It is the value in the current
11-04-2019
15
memory to be reflected.
[0052]
Next, the CPU 11 turns off signal transmission from the respective channels to the seventh and
eighth matrix buses 150-7 and 8 and sets the transmission level to 0 dB (S16). This setting is
performed on the current memory.
[0053]
Here, in the normal mode, whether or not the signal transmission to the seventh and eighth
matrix buses 150-7, 8 and the transmission level thereof are performed are the seventh and
eighth matrix buses 150-7 from the respective channels evacuated at step S15. , 8 according to
the value of the parameter set by the user regarding the presence / absence of signal
transmission and the transmission level. The operation of the cue key 212 and the cue button,
and settings relating to the cue do not affect the presence or absence of signal transmission to
the seventh and eighth matrix buses 150-7 and 8, and the transmission level thereof.
[0054]
However, in the queue mode, whether or not a signal is sent to the seventh and eighth matrix
buses 150-7, 8 and 7 and the sending level thereof are controlled in accordance with the setting
regarding the queue. For example, the signal transmission from the ch selected for monitoring to
the seventh and eighth matrix buses 150-7, 8 is turned on, and the signal transmission from the
other chs to these buses is turned off, etc. . In the process of step S16, as an initial value, setting
is made so as not to send a signal and not to change the signal. Further, the CPU 11 changes the
setting of the output patch 190 so that the signals of the seventh and eighth matrix output
channels 160-7 and 8 are output to the output port set as the signal output destination from the
additional queue bus. To do (S17). The output destination can be set by the queue B setting unit
410.

After step S17, the CPU 11 repeats the process of steps S18 to S20 with each channel included in
the sound signal processing apparatus 10 (which can be a target of monitoring) as a processing
target. That is, for the channel to be monitored (S18), if an additional queue bus (B) is included in
the queue output destination of that channel (S19), the seventh to eighth matrix buses 150 to
150 are selected. Signal transmission to -7, 8 is set to on (S20). The signal transmission remains
off for the other channels. The processes of steps S18 to S20 are processes of the output control
procedure. If the sound image localization of the monitor stereo signal is set in step S20, the
output level from the corresponding ch to both buses may be set according to the sound image
localization. The same applies to the setting of signal transmission to the subsequent fixed or
additional cue buses unless otherwise specified.
[0056]
According to the above process, it is possible to start output of a monitoring signal using the
additional queue bus according to the setting of the queue function that has already been made,
in response to the operation of enabling the additional queue bus.
[0057]
On the other hand, if the mode after switching in step S12 is the normal mode, the CPU 11 turns
off the operated queue addition setting button 401 (S21) and erases the queue B setting unit 410
from the queue setting screen 400 (S22) ).
Then, the transmission setting from each channel to the seventh and eighth matrix buses 150-7
and 8 in the normal mode saved in step S15 is restored to the current memory (S23), and the
process is ended. This return includes the setting of the output patch 190.
[0058]
By the above-described processing, the operations of the seventh and eighth matrix buses 150-7
and 8 can be restored to the operation as the matrix bus according to the operation of
invalidating the additional queue bus. Also, in this case, it is possible to perform an operation
according to the setting when the additional queue bus is enabled.

Next, FIG. 11 and FIG. 12 show flowcharts of processing when the operation of the cue key 212
or the cue button shown in FIG. 4 and FIG. 5 is detected. This process is a process for changing a
channel to be monitored, and is a process of output control procedure. Furthermore, here, it is
not necessary to distinguish whether the cue key 212 of the operation panel 200 is operated or
whether the cue button is operated by the external controller 30. The process which
distinguishes these and is performed is demonstrated by a modification.
[0060]
When detecting the operation of the queue key 212 or the queue button, the CPU 11 starts the
process shown in the flowchart of FIG. Here, it is assumed that "LAST CUE" is selected as a
method of selecting a monitoring target channel for both fixed and additional queue buses. In the
process of FIG. 11, first, the CPU 11 corresponds to the operated cue key 212 or a ch button (a
ch assigned as an operation target to the ch strip 210 to which the cue key 212 or the cue button
belongs, and is assumed here as chX It is determined whether or not the object is to be
monitored (S31).
[0061]
If No here, the CPU 11 newly selects chX as a monitor target (S32). Next, the CPU 11 confirms
the mode of the seventh and eighth matrix buses 150-7 and 8 (S33). Then, in the case of the
normal mode, since monitoring is performed using only the queue bus 170, the signal
transmission from the chX to the queue bus 170 is set to ON (S34).
[0062]
If the queue mode is selected in step S33, the output to the additional queue bus also needs to be
considered. Therefore, the CPU 11 refers to the queue output destination set in the process of
FIG. 9 for chX (S35). If this is only A, the same setting as in step S34 may be performed. If it is
only B, signal transmission from the chX to the seventh and eighth matrix buses 150-7, 8 is set to
on (S36). In the case of both A and B, signal transmission from the chX to the queue bus 170 and
the seventh and eighth matrix buses 150-7 and 8 is set to on (S37). By the processing up to this
point, the chX signal can be monitored at the output destination according to the setting of the
11-04-2019
18
queue output destination.
[0063]
Next, in accordance with the setting of “LAST CUE”, the CPU 11 performs processing for
removing the monitor target channel selected previously from the monitor target. That is, the
CPU 11 searches for a ch to be monitored other than chX (S38). If any ch is found, let it be chY.
Then, if there is chY (S39), the chY is excluded from the monitor target (S40), and the signal
transmission from the chY to the queue bus is set to OFF (S41 to S43). Here, if the seventh and
eighth matrix buses 150-7 and 8 are in the queue mode, the signal transmission to the queue bus
170 and the seventh and eighth matrix buses 150-7 and 8 is set to OFF (S42). However, in the
normal mode, only the signal transmission to the queue bus 170 is set to OFF (S43). In this case,
if the setting of signal transmission to the seventh and eighth matrix buses 150-7 and 8 is
changed, the operation as the matrix bus is affected.
[0064]
By the above processing, according to the setting of "LAST CUE", it is possible to maintain the
state in which only one ch is to be monitored. Further, in the case of Yes in step S31, the process
proceeds to the part shown in FIG. In this case, processing for removing chX from monitoring is
performed. This is to enable to toggle whether to monitor chX. The processes in steps S44 to S47
in FIG. 12 are the same as the processes in steps S40 to S43 in FIG. 11 except that ch is chX.
[0065]
In the sound signal processing apparatus 10 described above, the seventh and eighth matrix
buses 150-7 and 8 can be temporarily functioned as cue buses according to the user's operation,
and the number of monitor output systems can be increased. . Therefore, it is possible to
simultaneously monitor signals at a plurality of different places at low cost without adding a
queue bus. Therefore, it is possible to meet the demand for simultaneously monitoring two types
of signals and the demand for monitoring while switching two types of signals without
reselecting the monitoring target. As for the latter, it is possible to optionally select the monitor
signal mixed in each bus by switching whether to output the output from the fixed queue bus to
the monitor terminal or to output the output from the additional queue bus to the monitor
terminal. It can monitor while switching.

[0066]
In addition, since it is possible to set whether to monitor using a fixed queue bus or an additional
queue bus (or both) for each channel, efficient usage of two monitor outputs can be performed.
be able to. When the seventh and eighth matrix buses 150-7 and 8 are used as queue buses, the
number of matrix buses is reduced. However, since there are not many cases where all the matrix
buses are used, the function according to the needs of the user There is no loss of convenience if
you
[0067]
[Modification] The description of the embodiment is ended above, but the specific configuration
of the device, the number and type of buses and chs, the configuration of the operation panel and
screen, the specific processing procedure, etc. Of course, it is not limited to what was explained
in. For example, it may be considered that the output destination of the monitor signal is
automatically switched depending on whether the operation of the cue key is performed on the
operation panel 200 of the sound signal processing apparatus 10 or remotely from the external
controller 30.
[0068]
FIG. 13 and FIG. 14 show flowcharts of processing corresponding to FIG. 11 in this case. In FIG.
13 and FIG. 14, the same step numbers are given to the processing common to FIG. Further, in
the processing of FIG. 13 and FIG. 14, setting of the queue output destination for each channel is
invalidated. Further, in this example, it is assumed that the method of selecting a monitoring
target channel is “MIX CUE”.
[0069]
In the process of FIG. 13, the CPU 11 first determines whether the operation of the currently
detected cue key or cue button has been performed by the main unit or the remote control (SA).
Then, if this is the main body, the process proceeds to step S31 'and subsequent steps. In this
11-04-2019
20
process, the queue key 212 operated in step S31 'and the setting referred to in step SB is the
setting of the queue output destination when the queue key 212 of the operation panel 200 of
the main body is operated. Except for this, the processing is the same as the processing of steps
S31 to S37 of FIG. 11 and FIG. 12 (the processing in the case of Yes in step S31 is the same as
that of FIG.
[0070]
Further, if it is remote at step SA, the process proceeds to the process shown in FIG. Again, in
step S31 ′ ′, the operated button is the cue button, and the setting referred to in step SC is the
setting of the cue output destination when the cue button is operated by the remote operation
from the external controller 30. Except for the steps S31 to S37 of FIG. 11 and the process of
FIG. In the case of “MIX CUE”, the process of removing other channels from the monitoring
target is unnecessary, and in any case, the process ends by step S37.
[0071]
According to the above configuration, when different operators operate the operation panel 200
of the main body and the external controller 30, it is possible to easily monitor the signal of the
channel selected by oneself. For example, the signal of the channel to be monitored is output to a
fixed cue bus when operated from the main unit, to the additional cue bus when operated from
the remote, and the sound signal from each bus is sent to each operator. Output to a monitor
speaker or earphone used by
[0072]
Besides the above, buses that can be used as additional queue buses are not limited to matrix
buses. The matrix bus is used in the embodiment described above because it is necessary to
prepare signal transmission paths from many channels to the matrix bus, and it is relatively
necessary to use the signal transmission paths. It is because it is possible to make it usable as a
queue bus by small modifications.
[0073]
11-04-2019

That is, the matrix bus is generally provided as a bus that can mix the signal of the input ch and
the signal of the output ch after the signal of the input ch is mixed by the mixing bus. Therefore,
there is a common point in terms of functions with the cue bus that is desired to be able to
selectively input signals of various places including the input and output channels.
[0074]
However, other than the matrix bus, if there is a bus having a similar function, it can be easily
functioned as a queue bus as well. For example, when there is a path for transmitting a signal
directly from the output ch 140 to the mixing bus 130 of FIG. 2 without passing through the
output patch 190, a part of the mixing bus 130 may be similarly used as a cue bus. Conceivable.
For example, even when there is no signal transmission path from the matrix output channel
160, it is possible to use as an additional queue bus with a restriction that the signal of the
corresponding channel can not be monitored by the additional queue bus.
[0075]
In the above-described embodiment, only one additional queue bus is provided, but a plurality of
additional buses may be provided. For example, it is conceivable to use the fifth and sixth matrix
buses 150-5, 6 as an additional queue bus of the second system. Of course, three or more
additional queue buses may be provided. In this case, it is desirable to be able to select
independently whether to operate in the normal mode or the queue mode for the additional
queue bus of each system. In this way, the convenience regarding the queue function can be
further improved at low cost.
[0076]
Further, in the present invention, it is not essential that the sound signal processing apparatus 10
be provided with a fixed cue bus 170. It is also conceivable that all of the cue functions are
covered by the "additional" cue bus in the embodiment described above. Moreover, in the abovementioned embodiment, the example in which the cue bus 170 is a stereo bus has been
described. Then, in order to make an additional cue bus also a stereo bus, two matrix buses 150
are used as an additional cue bus as a set. However, this is not essential, and it is also conceivable
to provide a monaural additional cue bus using one matrix bus 150. It is also possible to provide
11-04-2019
22
an additional 5.1 ch queue bus using six matrix buses 150 as one set, and the number of
channels is not limited. In addition, the number of channels does not have to match between the
fixed queue bus and the additional queue bus.
[0077]
In addition to the above, in addition to the setting for each channel performed on the screen of
FIG. 8, the queue output destination may be configured to be able to perform temporary setting
common to all the channels to be preferentially applied. In this way, even if there is a setting for
each channel, it is possible to meet the requirement that the signal of a specific channel should
be monitored at a specific output destination even if it is temporarily contrary to it.
[0078]
A program, which is an embodiment of the present invention, causes one computer or a plurality
of computers to cooperate to control the sound signal processing apparatus to realize the control
functions related to the fixed and additional queue buses described above. Is a program of Then,
by causing a computer to execute such a program, the effects as described above can be
obtained.
[0079]
Such a program may be stored in the ROM or other non-volatile storage medium (flash memory,
EEPROM, etc.) provided in the computer from the beginning. However, it can also be provided by
being recorded on any non-volatile recording medium such as a memory card, CD, DVD, Blu-ray
disc and the like. Each of the above-described procedures can be executed by installing and
executing the program recorded on those recording media in a computer.
[0080]
Furthermore, it is possible to download from an external device connected to a network and
provided with a recording medium having a program recorded thereon or a program from the
external device stored in the storage means, and install it on a computer for execution. In
11-04-2019

addition, the configurations and modifications described above can be combined appropriately
and applied as long as no contradiction arises.
[0081]
As apparent from the above description, according to the present invention, it is possible to
provide a sound signal processing apparatus capable of simultaneously monitoring signals at a
plurality of different places at low cost.
