DESCRIPTION JP2004207823
In a digital mixing system that outputs signals of a plurality of input channels to a plurality of
MIX buses, it is possible to efficiently set the mixing state of signals of multiple systems. An
operation mode of a bus operator unit is selected by keys (202, 204). In the mix send mode, the
plurality of rotary encoders 218 become operators for adjusting the signal gain of each input
channel supplied to one designated MIX bus. Further, in the mix master mode, each encoder 218
serves as an operator for adjusting the output gain of each MIX bus. In addition, in the mix
master mode, the SEL key 222 is a key for designating a channel for performing detailed setting
such as sound quality. Further, when the CUE key 224 is operated in the mix master mode to be
turned on, the SEL key 222 is also interlocked and set to the on state. [Selected figure] Figure 6

described with reference to FIG. In FIG. 5, reference numerals 109-1 to 109-24 denote MIX bus
selection keys, and "24" are provided corresponding to MIX buses 32-1 to 32-24 of "24" system.
These MIX bus selection keys 109-1 to 109-24 are MIX buses (hereinafter referred to as
"operation target MIX buses") to be operated by the rotary encoder 514 and the ON key 512 etc.
provided in the input channel strip section 500. The MIX bus selection key 109-k is turned on in
response to the operation (on operation) of the MIX bus selection key 109-k corresponding to
the MIX bus 32-k other than the operation target MIX bus. The MIX bus 32-k is selected as the
operation target MIX bus. Therefore, when a plurality of MIX bus selection keys are sequentially
turned on, only the MIX bus 32-k corresponding to the MIX bus selection key 109-k finally
turned on becomes the operation target MIX bus. Further, in response to the operation (the off
operation) of the MIX bus selection key 109-k corresponding to the MIX bus 32-k that has
already been selected as the operation target MIX bus, the MIX bus selection key 109-k is
extinguished, and the operation target The MIX bus is not present (not selected). An LED display
104 displays the number ("1" to "24") of the operation target MIX bus or the character string "-"
indicating the non-selected state.
By the way, although details will be described later, in the present embodiment, the operation
mode is selected from among the “normal mode”, “FLIP mode”, “HA_REMOTE mode” and
“PAN mode” for the input channel strip unit 500. It is possible to choose. The details of each
operation mode will be described later. 102 is a FLIP key, 106 is an HA_REMOTE key, and 108 is
a PAN key, which toggles on / off states of "FLIP mode", "HA_REMOTE mode" and "PAN mode"
respectively, and the corresponding operation mode is set. If it is, the built-in LED is configured
to light. Here, the FLIP mode, the PAN mode and the HA_REMOTE mode can be exclusively set to
the on state. That is, when the corresponding operation mode is turned on by the operation of
the keys 102, 106, 108, the other operation modes are forcibly turned off. Then, if all of these

"3" modes are off, the operation mode is the normal mode. Although selection of the operation
target MIX bus by the MIX bus selection keys 109-1 to 109-24 can be executed even in the
HA_REMOTE mode or the PAN mode, the result is that the input channel strip unit 500 is only in
the normal mode and the FLIP mode. Reflected in 【0031】 3.2. Input Channel Strip
Section 500 Next, the detailed configuration of the input channel strip section 500 will be
described with reference to FIG. The input channel strip portion 500 is provided with "24"
channel strips 510-1 to 510-24. As described above, although the number of input channels is
"48", the input channels are divided into "2" layers every "24" channels. Then, when any layer is
selected, input channels belonging to the selected layer are assigned to the channel strips 510-1
to 510-24, and the volume etc. can be adjusted. Hereinafter, input channels assigned to
individual channel strips are referred to as “assigned input channels”. Since each channel strip
510-1 to 510-24 has the same configuration, the detailed configuration will be described by

encoder, which functions as follows based on the operation mode described above.
That is, the rotary encoder 514 serves as an operator for setting the send level (gain of the send
level adjusting units 64-1 to 64-24 in FIG. 4) to the operation target MIX bus in the normal
mode, and in the PAN mode It becomes an operator to adjust the PAN balance of each channel,
and in HA_REMOTE mode it becomes an operator to remotely control the device connected to
the other I / O unit 8. In FLIP mode it is the level of the assigned input channel (Fig. 4 Is an
operation element for adjusting the gain of the volume adjustment unit 56 in An ON key 512
functions as follows based on the operation mode. That is, the ON key 512 is a key for switching
the send on / off state (state of the signal switching units 62-1 to 62-24 in FIG. 4) to the
operation target MIX bus in the normal mode, and in the FLIP mode It becomes a key to switch
the on / off state (state of the on / off switching unit 54 in FIG. 4) of the assigned input channel
and does not function in the PAN mode, and in the HA_REMOTE mode, in the device connected
to the other I / O unit 8 It becomes a key for remote control which operates the on / off state of a
predetermined state. The ON key 512 has a built-in LED, and in any mode, the LED lights up
when the corresponding state is on, and turns off when the corresponding state is off. Reference
numeral 516 denotes an SEL key, which sets a channel to be operated in the selected channel
control unit 300 and the bus operator unit 200 (mix send mode) (hereinafter referred to as
“selected channel”) as an allocation input channel. It is a key to indicate that. Here, although
the SEL key 516 is provided for all the channel strips 510-1 to 510-24, only one of the SEL keys
can be selectively set to the on state. Therefore, when the SEL key 516 is pressed and set to the
on state in any channel strip, the SEL keys 516 of the other channel strips are forcibly set to the
off state. Reference numeral 518 denotes a display, which displays the channel name (up to 4
characters) of the assigned input channel. An ON key 520 functions as follows based on the
operation mode. That is, in the FLIP mode, the ON key 520 is a key for switching the send on /
off state (state of the signal switching units 62-1 to 62-24 in FIG. 4) to the operation target MIX
bus, and other than the FLIP mode In the operation mode, the key becomes a key for switching

the on / off state (the state of the on / off switching unit 54 in FIG. 4) of the assignment input
channel.
The ON key 520 is also provided with an LED that is turned on / off according to the
corresponding on / off state. An electric fader 524 functions as follows based on the operation
mode. That is, in the FLIP mode, the motorized fader 524 serves as an operating element for
setting the send level to the operation target MIX bus, and in the other operation mode, the level
of the assignment input channel (volume adjustment unit 56 in FIG. Become an operator to adjust
the gain). A CUE key 526 switches the on / off state of the CUE of the assigned input channel.
When the CUE is turned on, the audio signal of the assigned input channel is supplied to the CUE
bus 34. Here, there are two types of operation modes of the CUE key 526 and other CUE keys
described later, “MIX_CUE mode” and “LAST_CUE mode”. The MIX_CUE mode is an
operation mode that allows a plurality of CUE keys to be turned on, and audio signals relating to
a plurality of CUE keys set to the on state are mixed in the CUE bus 34, and the result is a CUE
signal. It will be output. On the other hand, the LAST_CUE mode is an operation mode in which
only the audio signal related to the CUE key finally set to the on state is supplied to the CUE bus
34, and the audio signals related to other CUE keys are automatically set to the off state. . An
operator for selecting the MIX_CUE mode or the LAST_CUE mode is provided in the other control
unit 770. Furthermore, when the input CUE interlocking function is turned on, in the LAST_CUE
mode, when the CUE key 526 of any channel strip 510-1 to 510-24 is turned on, the SEL key
516 is also switched. It interlocks and is set to ON state. Here is one of the features of the present
embodiment. That is, in the case where the LAST_CUE mode is selected, when the CUE key 526 is
operated and set to the on state in any channel strip, the state of the assigned input channel for
that channel strip is automatically selected by the selected channel control unit 300. Will be
reflected in the However, on the contrary, even when any one of the SEL keys 516 is operated,
the on / off state of the CUE key 526 belonging to the same channel strip is characterized in that
“do not interlock”. The reason why this operation method is adopted in the present
embodiment will be described.
First, the case where the operator sets the CUE key 526 to the ON state in the LAST_CUE mode in
a certain channel strip is “when it is desired to intensively monitor the audio signal of the
assignment input channel”. Then, “when it is desired to intensively monitor only a specific
input channel” is, in most cases, “when performing the sound quality adjustment of the input
channel”, that is, “select the relevant input channel” in the selected channel control unit 300.
It is empirically clear that it is equal to “when you want to set a channel”. Therefore, in this
embodiment, if only the CUE key 526 is operated in such a case, the operation target in the
channel to be monitored by the CUE bus 34, the selected channel control unit 300 and the bus
operator unit 200 (mix send mode) The channel is switched at the same time, thereby reducing
the operation effort by the operator. On the other hand, the reason why the CUE key 526 is not
08-05-2019
10
interlocked based on the operation of the SEL key 516 is that, even when the operator switches
the operation target channel in the selected channel control unit 300, the monitor target channel
by the CUE bus 34 This is because there are many cases where switching should not be
performed. For example, the case where the operator wants to adjust a specific input channel in
the selected channel control unit 300 while monitoring the overall sound quality and volume
corresponds to this. 【0041】 3.3. Assigned Channel Strip Unit 600 Next, the detailed
configuration of the assigned channel strip unit 600 will be described with reference to FIG. In
the figure, 630-1 to 630-8 are "8" channel strips, and each channel strip has a similar
configuration. Various functions can be assigned to these channel strips. A state in which
functions are assigned to each channel strip 630-1 to 630-8 in a one-to-one manner is referred
to as a "1 fader mode", and functions of a total of "7 fader modes" can be assigned to these
channel strips. A fader mode selection unit 610 selectively selects one of the fader modes using
keys 612 to 622 provided therein. The keys 612 to 622 are alternatively set to the on state. The
functions (operation modes) assigned to each channel strip include volume control of the input
channel (input channel mode), volume control of the MIX output channel (MIX output channel
mode), and gain of the built-in effector 26 (see FIG. 2). Adjustment (effector mode), and
adjustment of DCA level (DCA mode).
First, although the volume adjustment of the input channel can be performed in the abovedescribed input channel strip unit 500, by assigning the input channel to the channel strips 6301 to 630-8, the input channel belonging to the non-selected layer is allocated to the input
channel. Even with this, it is possible to adjust the volume with the fader. Further, a rotary
encoder is provided in the bus operator unit 200 (details will be described later), and the volume
control of each MIX output channel can be performed by this, but especially the MIX output with
high operation frequency. By assigning a channel or the like to any channel strip, the operability
of the MIX output channel can be enhanced. Next, “DCA (Ditigal Controlled Amplifier or Digitary
Controlled Attenuator)” will be described. The DCA assigns common faders (DCA faders)
different from the faders of each input channel to a plurality of input channels, and the gain set
by the DCA fader is the gain set by the faders of each input channel To determine the gains of the
plurality of input channels. The DCA mode is mainly used for volume control of large instruments
such as pianos and drums, and parts of orchestra, for example. Generally, the performance sound
of a large instrument such as a piano is collected by a plurality of microphones. The plurality of
microphones are respectively assigned to individual input channels to perform balance
adjustment. And these input channels are assigned to one DCA fader. Thus, the balance between
the sound signals collected from the individual microphones is adjusted by the faders of the
respective input channels, and the volume of the whole instrument is adjusted by the DCA faders.
Therefore, when the function of one of the channel strips 630-1 to 630-8 is assigned to the DCA,
the level of the input channel belonging to the DCA group, that is, the volume adjuster 56 (see
FIG. 4) is set. The level to be set is set to the multiplication result of the amount of operation of
the fader specific to the input channel and the amount of operation of the DCA fader. Next, in the
08-05-2019
11
inside of the channel strip 630-1, a display 631 displays the channel name (up to 4 characters)
assigned to the channel strip.
A DCA_MUTE key 632 functions only when the operation mode is the DCA mode. That is, when
the DCA_MUTE key 632 is set to the on state in the DCA mode, all levels of the input / output
channels included in the DCA group (gains of the volume adjuster 56) are set to “0”. An
electric fader 634 adjusts DCA level, input / output channel level and the like according to the
function assigned to the channel strip. A CUE key 636 is a key for on / off controlling the supply
of the output signal of the corresponding input / output channel or effector to the CUE bus 34 in
an operation mode other than the DCA mode. Further, in the DCA mode, the CUE key 636 is a
key that simultaneously turns on / off the CUE on / off switching unit 60 (see FIG. 4) related to
all the input channels belonging to the DCA group. The other channel strips 630-2 to 630-8
provided in the assigned channel strip unit 600 are also configured in the same manner as the
channel strip 630-1. 【0048】 3.4. Selected Channel Control Unit 300 Next, the selected
channel control unit 300 will be described in detail with reference to FIGS. 7 and 8. First, in FIG.
7, reference numeral 310 denotes an attenuator unit, which performs attenuation, phase
switching, insertion of an insertion effect, and the like in the sound quality adjustment units 52
and 72 of the selected channel. A noise gate unit 320 sets the noise gate in the sound quality
adjustment units 52 and 72. A level meter unit 340 displays the audio signal level of the selected
channel. Reference numeral 350 denotes a channel selection unit, which designates a selected
channel. The selected channel can also be designated by the SEL key 516 or the like provided in
the input channel strip portion 500, but can also be designated by the channel select portion
350. The display 352 displays the channel number of the selected channel inside the channel
selection unit 350. An INC key 354 increases the number of the selected channel by "1".
Reference numeral 356 is a DEC key, which decrements the number of the selected channel by
"1". A COPY key 364 copies the setting contents of the selected channel control unit 300 to a
copy buffer (a predetermined area in the RAM 14) when operated.
A PASTE key 368 reflects the setting contents stored in the copy buffer on the selected channel
control unit 300 as the setting contents of the selected channel. A group setting unit 370
performs operations such as adding a selected channel to a DCA group or the like, or excluding
the selected channel from the DCA group or the like. A delay unit 380 sets a delay characteristic
of the audio signal. Next, in FIG. 8, reference numeral 400 denotes a compressor unit, which sets
the built-in compressor in the sound quality adjustment units 52 and 72 of the selected channel.
Reference numeral 430 denotes an equalizer unit, which is a 4-band frequency consisting of
high, high and low mids (HIGH MID), low mids (LOW MID), and lows (LOW) in the equalizers of
the sound quality adjusters 52 and 72. The characteristic is set. Here, the rotary encoder 438
sets the center frequency of the high tone part (HIGH), and the set frequency is displayed on the
display 434. Further, the rotary encoder 437 adjusts the gain at the center frequency of the high
08-05-2019
12
tone (HIGH), and the rotary encoder 432 adjusts the Q value. These manipulated variables are
indicated by LEDs annularly arranged around the rotary encoder. Similar operators and
indicators are provided for the high mid-tone part (HIGH MID), the low mid-tone part (LOW MID)
and the low bass part (LOW). A high pass filter setting unit 480 sets a high pass filter to be
applied to the audio signal. 【0052】 3.5. Bus Operator Unit 200 Next, the detailed
configuration of the bus operator unit 200 will be described with reference to FIG. In the bus
operator unit 200, operation modes of "mix send mode" and "mix master mode" can be selected.
Here, the mix send mode is an operation mode for controlling signal levels (send levels) supplied
from the input channel to a plurality of MIX buses when any input channel is a selected channel.
For example, if the first input channel is selected by the SEL key 516 of the input channel strip
unit 500, a plurality of send level adjustment units 64-1 to 64-24 in the input channel
adjustment unit 30-1 (see FIG. 4). Signal level etc. is adjusted in the bus operator unit 200. The
mix master mode is a mode for adjusting the level or the like of the volume adjuster 76 in each of
the MIX output channel units 36-1 to 36-24.
When one of the output channels is the selected channel, only the mix master mode can be
selected as the operation mode, and the mix send mode can not be selected. Also, if the selected
channel is changed to any MIX output channel while the mix send mode is selected, the mix send
mode and the mix master mode are not selected, and the bus operator is selected. The operation
in unit 200 is nullified. Reference numeral 202 denotes a mix send key, and reference numeral
204 denotes a mix master key. Each time the key is pressed, the operation mode is switched to
the “mix send mode” or “mix master mode”, and the corresponding operation mode is
selected. The internal LED turns on. Reference numerals 210-1 to 210-24 denote bus control
units, which correspond to the MIX buses 32-1 to 32-24 in any operation mode. Inside the bus
control unit 210-1, 216 is an ON key, 218 is a rotary encoder, 224 is a CUE key, and 222 is a
SEL key. In the other bus control units 210-2 to 210-24, similar operators are provided. The
functions of these operators will be described in detail below for each operation mode. 【
0054】 3.5.1. Mix Send Mode First, in the “mix send mode”, the bus control unit 210n (where n = 1 to 24) is associated with the MIX bus 32-n, and the bus control unit 210-n is a
selected channel. The operator group is configured to perform control related to the signal
supply from the m-th input channel to the MIX bus 32-n. In this operation mode, the ON key 216
toggles on / off of the signal supply from the m-th input channel to the MIX bus 32-n, that is, the
on / off state of the signal switching unit 62-n in the input channel adjustment unit 30-m.
Become a key. Further, the rotary encoder 218 serves as an operation element for adjusting the
level of the send level adjustment section 64-n in the input channel adjustment section 30-m.
Also, in this mode, the CUE key 224 does not function, and the key is always turned off. Further,
the function of the SEL key 222 is the same as the function of the MIX bus selection keys 109-1
to 109-24 provided in the bus selection unit 100, and the SEL key 222 interlocks with the
corresponding MIX bus selection key 109-n. And it becomes a key to select the target MIX bus.
08-05-2019
13
However, the SEL key 222 is always turned off, and the display of the operation target MIX bus is
performed only by the MIX bus selection key 109-n. 【0056】 3.5.2. Mix Master Mode
Next, in the mix master mode, the bus control unit 210-k (where k = 1 to 24) is associated with
the MIX output channel unit 36-k, and control in the MIX output channel unit 36-k Become
operators. In this operation mode, the ON key 216 is a key that toggles the on / off state of the
entire MIX output channel section 36-k, that is, the state of the on / off switching section 74. The
rotary encoder 218 also serves as an operating element for adjusting the level of the volume
adjustment unit 76 in the MIX output channel unit 36-k. Further, in this operation mode, the CUE
key 224 toggles whether the CUE on / off state of the CUE on / off switching section 80, that is,
whether the audio signal of the MIX output channel section 36-k is to be supplied to the CUE bus
34 or not. It becomes a key to switch. Further, the SEL key 222 is a key for setting the MIX
output channel section 36-k as a selected channel (a channel to be operated in the selected
channel control section 300 etc.). As described above, when one of the MIX output channels is
the selected channel, the operation mode of the bus operator unit 200 can not be set to the mix
send mode. Here, the operation mode of the CUE key 224 is selected from the LAST_CUE mode
or the MIX_CUE mode, as with the other CUE keys described above. Here, the operation in the
LAST_CUE mode when the output CUE interlocking function is turned on has one of the features
of the present embodiment. That is, when the output CUE interlocking function is on and the
LAST_CUE mode is selected, when the CUE key 224 is set to the on state in any bus control unit
210-k, the bus control unit 210-k The SEL key 222 belonging to is also interlocked and set to the
on state. However, on the contrary, even when any one of the SEL keys 222 is operated, the on /
off state of the CUE key 224 belonging to the same bus control unit is characterized in that “do
not interlock”. The reason why this operation method is adopted in the present embodiment is
the same as the reason why the operation method of the SEL key 516 and the CUE key 526 in
the input channel strip section 500 described above is adopted.
That is, the case where the operator sets the CUE key 224 in the on state in the LAST_CUE mode
in a certain bus control unit 210-k is, in most cases, "when the sound quality adjustment of the
MIX output channel unit is performed". Therefore, in the present embodiment, as in the case of
the input channel strip unit 500, if only the CUE key 224 is operated in this case, the monitor
target channel by the CUE bus 34 and the operation target in the selected channel control unit
300. The channel is switched at the same time, thereby reducing the operation effort by the
operator. On the other hand, it is conceivable that the operator may want to adjust a specific MIX
output channel in the selected channel control unit 300 while monitoring the overall sound
quality and volume, so even if the SEL key 222 is operated, the CUE key 224 The status is not
linked. Furthermore, the following interlocking function of the CUE key 224, which operates
regardless of either the LAST_CUE mode or the MIX_CUE mode, is also characterized by the
present embodiment. (Interlocking Function 1) First, when any of the MIX bus selection keys
109-k is set to ON in the above-described bus selection unit 100 when the bus selection
08-05-2019
14
interlocking function is ON, the MIX bus 32-k is selected. When the CUE on / off switching unit
80 of the MIX output channel unit 36-k corresponding to is in the on state (the interlocking CUE
is on) and the bus operator unit 200 is in the mix master mode, the corresponding bus control
unit 210. The CUE key 224 belonging to -k is turned on. (Interlocking Function 2) Further, when
the CUE (existing CUE) of any input channel or MIX output channel is already on when the MIX
bus selection key 109-k is turned on, the existing CUE is temporary. In this case, the interlocking
CUE of the MIX output channel unit 36-k is turned on. Furthermore, if another MIX bus selection
key 109-j is turned on in that state, the immediately preceding interlocking CUE is released, and
instead, the interlocking CUE of the MIX output channel unit 36-j is turned on. (Interlocking
Function 3) When the interlocking CUE is in the on state and the MIX bus selection key 109-k of
the operation target MIX bus is turned off, the interlocking CUE is released. Here, when the
existing CUE is temporarily released at the start of the interlocking CUE, the existing CUE
temporarily released is recovered at that time.
(Interlocking Function 4) When the interlocking CUE is on and the CUE key 526 to 224 of any
input channel or MIX output channel is turned on, the interlocking CUE is released and turned
on. Only the CUE corresponding to the operated CUE key is turned on. Hereinafter, the
significance of providing each function will be described. (Regarding interlocking function 1) In
the conventional mixing system, when adjusting the monitor signal to be returned to the
performer at the concert or the monitor signal to be returned to the performer of the program,
the monitor is performed by the operation of the MIX bus selection key 109-k. After selecting
MIX bus 32-k which is mixing signals as the operation target MIX bus, it is necessary to further
operate the CUE key 224 in the bus control unit 210-k corresponding to the operation target
MIX bus. In the mixing system of the present embodiment, by setting the bus selection
interlocking function to the on state, it becomes possible to simultaneously execute the
specification of the operation target MIX bus and the setting of the interlocking CUE of the
operation target MIX bus. (Regarding Interlocking Function 2) When the interlocking function 1
is executed, even if a CUE signal has already been specified in the LAST_CUE mode or MIX_CUE
mode, the CUE signal is selected in response to the ON operation of the MIX bus selection key
109-k. It is possible to cancel the existing CUE and set a single interlocking CUE for the operation
target MIX bus. (Regarding Interlocking Function 3) Further, when the OFF operation of the MIX
bus selection key 109-k is executed, the interlocking CUE is released, and the state of the CUE
before the interlocking CUE is executed is recovered. Therefore, even when the operator is
performing a normal operation and receives an adjustment request for the monitor signal by an
interrupt, the conventional operation can be promptly started after the adjustment of the monitor
signal. Since the adjustment request of the monitor signal is a temporary operation and occurs
irregularly, the operator's labor can be greatly reduced by rapidly switching the adjustment of
the monitor signal and the normal operation. . (Regarding Interlocking Function 4) Further, it is
also possible to set a new CUE state by operating the CUE keys 526 and 224 of the input channel
or the MIX output channel. Furthermore, since the CUE keys 526 and 224 are toggle keys,
08-05-2019
15
respectively, the new CUE state may be canceled and all CUEs may be released by continuously
operating the same CUE key. it can.
【0069】 3.5.3. Regarding the Relationship Between the Bus Operator Unit 200 and
Other Parts As described above, in the bus operator unit 200, the bus control units 210-1 to
210-24 are arranged in eight rows and three columns. That is, the bus control units 210-1 to
210-8 are sequentially arranged in the uppermost row, the bus control units 210-9 to 210-16
are sequentially arranged in the second row, and the bus control unit 210- 17 to 210-14 are
sequentially arranged. With this arrangement, the operator can very easily identify the bus
control units 210-1 to 210-24 corresponding to the input channel or MIX bus to be adjusted.
Further, in the present embodiment, the bus selection unit 100, the bus operator unit 200, the
selection channel control unit 300, and the display unit 720 are sequentially arranged from left
to right in parallel to the input channel strip unit 500. Is also one of the features. First, when
setting such as limiter processing is performed in the selected channel control unit 300, a graph
of the set characteristics is displayed on the display 720 adjacent to the selected channel control
unit 300. Thus, the operator can set the characteristics while easily comparing the relationship
between the operation position of each operation element in the selection channel control unit
300 and the graph of the characteristics being set. On the other hand, since the setting content in
the bus operator unit 200 is a gain or the like, it is scarcely necessary to compare in particular
any graph with the operation content of the bus operator unit 200. Therefore, even if the
distance between the bus operator unit 200 and the display unit 720 is large, no problem occurs.
By the way, in the conventional mixing system (for example, the mixing system listed in NonPatent Document 1), the send level to the group of operators unrelated to the display content of
the display 720, ie, a plurality of MIX buses, Since the operator group to be set is included in the
selected channel control unit 300, the number of operators in the selected channel control unit
300 increases, and there is a problem that the operation is complicated and difficult to use.
Furthermore, in the technique disclosed in Non-Patent Document 1, the selection channel control
unit for the input channel and the selection channel control unit for the MIX output channel are
separately provided, so the number of operators increases. There was also a problem of that. On
the other hand, according to the present embodiment, the operator group which is
conventionally included in the selected channel control unit 300, that is, the operator group for
setting send levels for a plurality of MIX buses is the bus operator unit 200. , And are arranged
next to the selected channel control unit 300 and away from the display 720.
As a result, the operator can easily understand the arrangement of the controls, and the distance
of the viewpoint movement can be shortened. Furthermore, in the present embodiment,
switching of the operation mode corresponds to “control of signals sent out from one selected
channel to a plurality of MIX buses” and “corresponding to a plurality of MIX buses”.
Therefore, since the bus operator section 200 can be shared for control of signals sent from a
08-05-2019
16
plurality of MIX output channels, the number of operators can be significantly reduced, thereby
further improving operability. it can. Moreover, these two types of signal control are control
corresponding to each of the plurality of MIX buses 32-1 to 32-24, and the bus control unit 210k corresponding to any MIX bus 32-k operates. It is constant regardless of the mode. Therefore,
according to the present embodiment, the special relationship is that the correspondence
between the target MIX bus and the operators is clear and easy to understand even though the
plurality of functions according to the operation mode are assigned to the common operators.
The effect of Further, in the present embodiment, the operators corresponding to the respective
MIX buses of the bus operator section 200 are arranged in eight rows and three columns. This
arrangement is exactly the same as the arrangement of the MIX bus selection keys 109-1 to 10924 in the bus selection unit 100 for switching the function of the rotary encoder 514 etc. of the
input channel strip unit 500. Therefore, when the operator operates the bus selection unit 100
after operating the bus operation unit 200 or in the reverse order, the relationship between the
individual operation units and the corresponding MIX bus can be easily visually made. It can be
recognized. Furthermore, when the operation mode of the bus operator unit 200 is the mix send
mode, the SEL key 222 in the bus operator unit 200 is the same as the MIX bus selection keys
109-1 to 109-24 in the bus selection unit 100. It can play a function. Thereby, when send level
adjustment from one selected channel in the bus operator unit 200 to a plurality of MIX buses
and send level adjustment to one MIX bus by the rotary encoder 514 in the input channel strip
unit 500 are alternately performed. In the embodiment, the present embodiment can exhibit high
operability. 【0075】 4. Operation of Embodiment 4.1. General Operation Next, the
operation of the mixing system of the present embodiment will be described. First, in the mixing
system, when an operation event of an operator such as any fader, rotary encoder or key occurs,
a routine corresponding to the content of the operation is activated.
In particular, when an operation event related to general volume adjustment (except for special
operation events such as scene reproduction) occurs, an operation event routine shown in FIG.
11 is started. In the drawing, when the process proceeds to step SP2, the contents of the current
area including the current scene area 14a are updated based on the operation contents. For
example, when the electric fader or rotary encoder is operated, control data (level data, frequency
data, etc.) corresponding to the operation amount after the operation is stored in the
corresponding area of the current area, and when the key is operated The on / off state and the
like after the operation are stored. Next, when the process proceeds to step SP4, various
parameters in the mixing algorithm (see FIGS. 3 and 4), that is, the contents of parameter
registers provided in the signal processing unit 6 are updated based on the current region. Next,
when the process proceeds to step SP6, various settings on the operation panel 2 are executed
based on the contents of the current area after the update. For example, turning on / off of the
LED inside the key, turning on / off of the LED around the rotary encoder, changing the display
contents of various displays, driving of the electric fader, etc. are executed. In the mixing system
of the present embodiment, three types of interlocking of the input CUE interlocking function,
08-05-2019
17
the output CUE interlocking function, and the bus selection interlocking function are possible,
but all processing relating to these interlocking is performed in step SP2. That is, in step SP2, the
control data corresponding to the operator in the current area is updated based on the operation
content of the operated operator, and the interlocking function related to the operator is set to
the ON state. If it is set to the on state, control data of other operators to be interlocked
according to the interlocked function is also updated. 【0078】 4.2. Specific Operation
Example Next, a representative operation example in the present embodiment will be specifically
described. As an example, it is assumed that the second MIX output channel is assigned as a
monitor signal for a certain performer on the stage. Then, regarding the monitor signal, it is
assumed that there is a request "I want the volume to be raised overall and the percussion sound
to be dropped". The operator's operation to satisfy such a demand is as follows. First, when the
operator depresses the mix master key 204 in the bus operator unit 200, the operation mode of
the bus operator unit 200 is set to the mix master mode, and each bus control unit 210-k has a
MIX output channel unit. The setting contents of 36-k are reflected.
That is, according to the gain set in the volume adjuster 76 (see FIG. 4) in each MIX output
channel unit 36-k, the lighting state of the LED around the rotary encoder 218 in each bus
control unit 210-k is It is set. Next, when the operator turns on the MIX bus selection key 109-2
in the bus selection unit 100, the second MIX output channel corresponding to the MIX bus
selection key 109-2 is selected as the operation target MIX bus. At that time, when the bus
selection interlocking function is set to the on state, the CUE on / off switching unit 80 of the
MIX output channel unit 36-2 is automatically set to the on state as the interlocking CUE. That is,
the monitor signal of the second MIX output channel is emitted from the headphone or monitor
speaker. When the operation mode of the bus operator unit 200 is set to the mix master mode,
the CUE key 224 of the bus control unit 210-2 is also automatically turned on. Then, the existing
CUE state before the interlocking CUE is set is temporarily stored in a predetermined area in the
RAM 14. Furthermore, when the operation mode of the input channel strip unit 500 is the
normal mode by setting the second MIX output channel to the operation target MIX bus, the
rotary encoder 514 included in each channel strip 510-1 to 510-24 is used. Represents the send
level from each input channel to the second MIX output channel at that time. Accordingly, the
operator can adjust the overall volume of the second MIX output channel by operating the rotary
encoder 218 in the bus control unit 210-2 corresponding to the second MIX output channel.
Further, by operating the rotary encoder 514 of the channel related to “percussion” among the
input channels, it is possible to reduce the “percussion” send level. Then, since the CUE on /
off switching unit 80 of the MIX output channel unit 36-2 is automatically set to the on state as
the interlocking CUE, these operations may be performed while actually listening to the monitor
sound of the second MIX output channel. it can. Then, after the setting for the second MIX
output channel is completed, when the operator presses the MIX bus selection key 109-2 again
(off operation), the CUE state before the interlock CUE is set is the above-described
predetermined state in the RAM 14 It is read from the area and reproduced on the operation

panel 2.
By this, the operator can immediately continue the adjustment, etc. which have been performed
previously. 【0084】 5. Modifications The present invention is not limited to the abovedescribed embodiment, and various modifications can be made, for example, as follows.
(1)
In each of the above embodiments, the mixing system is controlled by a program operating on
the CPU 10. However, only the program may be stored and distributed in a recording medium
such as a CD-ROM or a flexible disk, or may be distributed through a transmission path. it can.
(2) In the above embodiment, the bus control units 210-1 to 210-24 are arranged in three rows
and eight columns, but the arrangement direction of the bus control units 210-1 to 210-24 is the
same. It is not limited. That is, if P and Q are arbitrary natural numbers greater than or equal to
"2" and "bus control units" provided only for "P × Q" are arranged in horizontal P rows and
vertical Q columns, all of them fall within the scope of the present invention. included.
Furthermore, if both P and Q are natural numbers of "3" or more, the entire array shape of the
bus control units 210-1 to 210-24 can be made closer to a square, which is more preferable.
Similarly, in the bus selection unit 100, MIX bus selection keys 109-1 to 109-24 are arranged in
three horizontal rows and eight vertical columns, but R and S are arbitrary natural numbers of
"2" or more, "R x S" If the MIX bus selection keys 109-1 to 109-24 provided with only "" are
arranged in R rows and S columns, they are all included in the category of the present invention.
Also in this case, it is more preferable to set R and S as natural numbers of 3 or more, since the
arrangement of the entire MIX bus selection keys 109,..., 109 can be made closer to a square. (3)
In the above embodiment, the CUE key 526 is not interlocked by the operation of the SEL key
516, and the CUE key 224 is not interlocked by the operation of the SEL key 222. This is, as
described above, in consideration of performing adjustment of a specific MIX output channel in
the selected channel control unit 300 while monitoring the overall sound quality and volume.
However, depending on the use state of the mixing system, it may be desirable to interlock these
keys, so the CUE key 224 or 526 may be interlocked by the operation of the SEL key 222 or 516.
(4) Further, according to the bus selection interlocking function of the above embodiment, the
CUE on / off switching in the MIX output channel unit 36-k is performed for both the on
operation and the off operation of the MIX bus selection key 109-k. The state of the unit 80 is
interlocked, but the state of the CUE on / off switching unit 80 is interlocked and set to the ON
state in response to the ON operation "only" of the MIX bus selection key 109-k, and the OFF
operation is performed. You may not make it interlock.
(5) In the above embodiment, each part of the mixing system is controlled by the program stored
in the flash memory 12. However, only this program is stored in a recording medium such as a

CD-ROM or a flexible disk It can also be distributed or through a transmission line. As described
above, according to the present invention, the display unit, the selected channel control unit, and
the delivery control unit are arranged in line in that order on the back side of the input channel
unit, or in the operation mode. Since the operation of the transmission control unit is switched
according to the above, it is possible to efficiently set the mixing state of signals of multiple
systems. BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an overall block diagram of a mixing
