control method of an audio signal editing apparatus suitable for mixing in a concert hall or the
like, an audio signal editing apparatus, and a program.
[0002]
2. Description of the Related Art In a mixing console, it is necessary to assign a plurality of input
signals and a plurality of output signals to a plurality of input channels and output channels,
respectively. Among these, "input signal" has digital input and analog input, and analog input is
classified into microphone input, line input, etc. according to the level. The necessary input unit
differs depending on the type of such input signal. The output units are also different depending
on whether the output signal is digital or analog. If appropriate input / output channels can be
assigned to these units without changing the physical connection state between the plurality of
input / output units and the mixing console, faders or the like may be selected according to the
current situation in a concert or the like. Placement can be optimized. For this reason, many
mixing consoles are provided with an input / output patch which can assign physical input /
output signal connections to an arbitrary input / output channel.

In the card selection window 400, when the operator selects a card to be inserted, the selection
result is reflected in the unit selection window 200. For example, when the operator clicks the
icon 404 related to the microphone level input card (model number LMY2-ML) with the pointing
device, the card selection window 400 is erased from the display 1002, and the input unit
window 250 is displayed as shown in FIG. It will be displayed again.
[0038]
2.1.9.
Setting Parameters in the Input Unit Window 250 (FIGS. 23 and 24) In FIG. 23, an image
imitating a microphone level input card (model number LMY2-ML) is displayed in the first slot of
the card display unit 260. . The appearance configuration of the card is also similar to that shown
in this image. However, since the card is a virtual card which is not actually connected, the
character string "VIRTUAL" is displayed at the bottom of the image. Two microphone level analog
signals in the microphone level input card (model number LMY2-ML) are called microphone
channels 1 and 2. In each of the microphone channels 1 and 2, terminals A and B of two cannon
connectors are provided, respectively, and any one of them can be selected as an input terminal.
[0039]
In addition, on the card status display unit 264, an operator image for setting various parameters
for the microphone level input card (model number LMY2-ML) is displayed. That is, by moving
the cursor 201 on each controller image and performing a predetermined operation, parameters
corresponding to each controller image can be set. First, reference numerals 281 and 282 denote
terminal selection buttons, which select terminals used as microphone channels 1 and 2 from
terminals A and B alternatively. A phantom power button 283 is provided for each of the
terminals 1A, 1B, 2A, 2B, and whether to supply phantom power (power required for a condenser
microphone or the like) to the microphones connected to the terminals. Choose
[0040]
A phase inversion button 284 selects whether to invert the phase of the input audio signal. This
is because when picking up audio signals from a plurality of microphones with respect to the
same sound source, problems such as the low-pitched range may occur if the phase of the audio
signals of each microphone is inverted. A head amplifier volume operator 285 sets an
09-05-2019
14
amplification amount of the audio signal. Reference numeral 286 denotes a gain display unit,
which displays the gain set by the head amplifier volume control 285 as a numerical value
(decibel). The results of various settings made in the card status display unit 264 are shown in
FIG.
[0041]
2.1.10.
Library Window 450 (FIG. 25) Here, when the operator performs a predetermined operation, a
library window 450 shown in FIG. 25 is displayed on the display 1002. In the library window
450, reference numeral 452 denotes a library list, which displays the library number of the
setting contents in the digital mixing system and the library name. When any row in the library
list 452 is clicked on with a pointing device, the library in the row is selected as a processing
target.
[0042]
After selecting the library to be processed, when the operator clicks the store button 456 with
the pointing device, the previously set contents are stored in the library in the flash memory
1020. Further, when the operator clicks the recall button 454 with the pointing device, various
parameters in the console 1000, the engine 2000, etc. are set based on the setting contents
already stored in the library. Reference numeral 458 denotes a title edit button, which when
clicked by the operator, executes processing for editing the library name of the selected library.
An EXIT button 460 is clicked, and the library window 450 is closed.
[0043]
2.1.11.
Connection of Real Units (FIG. 26) As described above, the units 2200 to 2400 can be hotplugged with respect to the engine 2000 as described above. Therefore, during operation of the
digital mixing system, any unit set as a virtual unit may actually be connected to the engine
2000. In such a case, a conflict warning window 500 as shown in FIG. 26 is displayed. In this
window, the operator is warned that "the real unit has been connected to the first input unit of
the unit set as a virtual unit".
09-05-2019
15
[0044]
In the conflict warning window 500, only the OK button 502 can be operated. When the operator
clicks the OK button 502 with a pointing device, the conflict warning window 500 is closed. This
is just the difference between the "virtual unit" and the "real unit" even if a "conflict" occurs, and
there is no contradiction in the unit model number itself, so only the OK button 502 can be
operated. The
[0045]
2.1.12.
Reflecting real unitization in the unit selection window 200 (FIG. 13) Thus, when the unit related
to the first input terminal is changed from the virtual unit to the real unit and the unit selection
window 200 is displayed thereafter The window is changed as shown in FIG. That is, the display
state of the icon 211 related to the first input terminal is changed to "grey letter on white"
indicating the real unit.
[0046]
2.1.13.
Reflection of Realization in the Input Unit Window 250 (FIG. 14) When the icon 211 is clicked
with the pointing device in FIG. 13, the input unit window 250 of the unit is displayed as
described above. However, since the icon 211 is changed to that of a real unit, the input unit
window 250 reflects the state of the actual AD unit 2200 (model number AI8). Furthermore, with
the realization of a real unit, the unit name display unit 254 is also changed to "gray text on a
white background".
[0047]
A display example of the input unit window 250 for the real unit is shown in FIG. In the figure, in
the card display unit 260, the microphone level input card (model number LMY2-ML) is in the
first to fourth slots, and the line level input card (model number LMY4- in the fifth to eighth
slots). AD) is displayed. There is no card indicated as "VIRTUAL" in each card in FIG. That is, the
09-05-2019
16
card as shown in this window is actually inserted in the AD unit 2200.
[0048]
In the illustrated state, since the first slot of the card display unit 260 is in the selected state, the
card status display unit 264 displays the parameters of the microphone level input card (model
number LMY2-ML) inserted here. ing. The parameters set in the card correspond to the
parameters previously set in the virtual card of the virtual unit, that is, the parameters shown in
the card status display section 264 of FIG.
[0049]
Thus, according to the present embodiment, the parameters set to the virtual unit or virtual card
are identical to those of the real unit or real card when the real unit or real card of the same
model number is connected. It will be used as a parameter as it is. In FIG. 24, the virtual card for
which the parameter is set is only the virtual card of the first slot, and the parameter is not set
for the other (second to eighth) slots. In such a case, the parameters of the card inserted in these
slots are set to the default state. The default state is, for example, a state where the gain is
narrowed down in the microphone level input card (model number LMY2-ML).
[0050]
2.1.14.
Processing when a real unit is removed (FIG. 15) Here, when the AD unit 2200 (model number
AI8) set as a real unit is removed, the detachment warning window 550 shown in FIG. Is
displayed on. In this window, the operator is warned that "the AD unit 2200 (model number AI8)
has been removed from the real unit" and two buttons 552 and 554 are displayed.
[0051]
The button 552 instructs to "leave the detached unit as it is as a virtual unit", and the button 554
instructs to "delete the detached unit". Therefore, when the operator clicks the button 552 with
the pointing device, the unit selection window 200 returns to the state shown in FIG. 21, while
09-05-2019
17
clicking the button 554 returns to the state shown in FIG.
[0052]
2.1.15.
Display / Setting of Input Patch Unit 112 (FIG. 8) When the operator performs a predetermined
operation, an input patch display / setting window 600 shown in FIG. 8 is displayed on the
display 1002. The window 600 is for displaying the setting contents in the input patch unit 112.
In this figure, a matrix is formed by physical input channels (columns) and logical input channels
(rows) in the input channel adjustment units 114 and 116. For example, IN 1 (AI 8) is
displayed at the left end of the vertical axis title portion 602. This means that the AD unit 2200
(model number AI8) is connected to the first input terminal of the engine 2000 or the
connection of the unit is scheduled and set as a virtual unit .
[0053]
The fact that the numbers 1 , 2 and 3 are displayed immediately below IN 1 (AI
8) means that some card is inserted in slots 1 to 3 in the unit, or some virtual・ Indicates that
the card is set. Immediately below that, three sets of numbers 1 and 2 are arranged,
which indicate physical input channels in the card. That is, since there are two input channels per
card, it is understood that the card is a microphone level input card (model number LMY2-ML).
[0054]
Furthermore, IN 3 (AI8) is displayed on the right of the IN 1 (AI 8) portion. This means
that the AD unit 2200 (model number AI8) is also connected to the third input terminal of the
engine 2000 or is set as a virtual unit. Also in the unit of the third input terminal, a card having
two input channels (i.e., model number LMY2-ML) is inserted in the first to third slots or set as a
virtual card.
[0055]
On the other hand, each row of the input patch display / setting window 600 corresponds to
09-05-2019
18
each input channel of the monaural input channel adjustment unit 114 and each input channel of
the stereo input channel adjustment unit 116 (although hidden in the figure). There is. These
input channels of the input channel adjusting units 114 and 116 are called logical channels .
Circles are appropriately displayed at intersections of the rows and columns of the window 600.
This indicates that the physical channel of the column to which the circle belongs is assigned as
the input channel of the row to which the circle belongs. As described above, the setting state of
the input patch unit 112 is displayed by the matrix of the window 600.
[0056]
In the illustrated example, each channel in two AD units 2200 (model number AI8) connected to
the first and third input terminals of the engine 2000 is the first to twelfth in the monaural input
channel adjustment unit 114. Is assigned to the logical channel of the The operator can set the
correspondence between the physical channel and the logical channel by clicking on any
intersection on the matrix with the pointing device.
[0057]
2.1.16.
Insertion of Real Unit (FIGS. 9 and 10) Here, when a new input unit (real unit) is connected, a
conflict warning window 650 as shown in FIG. 9 is displayed on the display 1002. FIG. In the
illustrated example, a new AD unit 2200 (model number AI8) is connected to the second input
terminal which has not been connected until now and is not scheduled to be connected as a
virtual unit either. Is alerted to the operator. The only button that can be operated in this window
650 is the OK button 652. Then, when the operator clicks the OK button 652 with the pointing
device, the window 600 is updated to reflect the contents of this new input unit.
[0058]
Here, an example of the updated input patch display / setting window 600 is shown in FIG. In the
vertical axis title portion 602 in this figure, a portion indicated as "IN 2 (AI 8)" is added between
"IN 1 (AI 8)" and "IN 3 (AI 8)". This corresponds to the AD unit 2200 (model number AI8) newly
connected to the second input terminal, and the card also has two input channels in the first to
third slots (ie, model number LMY2). It can be seen that -ML) is inserted. However, in the
illustrated state, the correspondence between physical channels and logical channels is not
09-05-2019
19
changed at all. That is, each physical channel of the newly connected input unit is not associated
with any logical channel.
[0059]
2.1.17.
Setting Parameters in the Input Channel Setting Window 750 (FIG. 27) When the operator
performs a predetermined operation, the input channel setting window 750 for the logical
channel in the input channel adjustment units 114 and 116 is displayed on the display 1002. An
example is shown in FIG. As described above, parameter setting of each card in the input / output
unit can be performed in the input unit window 250 (FIG. 23, FIG. 24). However, the setting of
the card associated as the logical channel in the input channel adjustment units 114 and 116 can
also be executed in this input channel setting window 750.
[0060]
For example, in FIG. 27, in order of input channel numbers (CH1, CH2, CH3,...), Elements for
setting for each input channel are displayed. In this figure, channels CH1 to CH8 are associated
with microphone level input cards, and terminal selection buttons 781 and 782, phantom power
buttons 783, phase reversal buttons 784, and head similar to the components 281 to 286
described in FIG. An amplifier volume control 785 and a gain display 786 are displayed.
[0061]
Therefore, the operator can perform the parameter setting operation without being aware of
which physical channel each logical channel corresponds to. The physical channel associated
with each logical channel is specified in the card display unit 787. For example, in CH1, the card
display 787 displays "I1A8: 1-1". This is the meaning of "the first channel of the card inserted in
the first slot of the AD unit 2200 (model number AI8) connected to the first input terminal".

Auto Setup Operation (FIGS. 11 and 12) In the input patch display / setting window 600 shown
in FIG. 10, an "AUTO SETUP" button 610 is displayed. This button is a button for instructing to
correct the correspondence between the physical channel and the logical channel so that the
circles on the matrix are aligned in a diagonal line. However, the 8-channel audio signal returned
from the built-in effector 108 is corrected so as to be sequentially associated with the 4 × 2
channel input in the stereo input channel adjustment unit 116. When the operator clicks the
AUTO SETUP button 610 with the pointing device, an AUTO SETUP confirmation
window 700 shown in FIG. 11 is displayed on the display 1002.
[0063]
This window is a window for confirming to the operator whether "AUTO SETUP" is actually to be
executed, and the OK button 702 and the cancel button 704 are displayed as operable buttons.
Here, when the operator clicks the cancel button 704 with the pointing device, AUTO SETUP
is canceled, and the display on the display 1002 returns to the state shown in FIG. On the other
hand, when the operator clicks the OK button 702, "AUTO SETUP" is executed, and the input
patch display / setting window 600 is changed as shown in FIG.
[0064]
In FIG. 12, the correspondence is corrected such that the circles on the matrix are arranged in a
straight line. That is, the input units are arranged from the left side in the order of the connected
input terminals, and in each input unit, physical channels are arranged in order of slot number
and in order of input channel number of the card. However, the arrangement of the logical
channels corresponding to each row is not changed. As a result, the respective channels in the
three AD units 2200 (model number AI8) connected to the first to third input terminals are
sequentially associated with the first to eighteenth logical channels.
[0065]
2.1.19.
The operation described above in the personal computer 1106, 2106 is the operation executed
in the console 1000, but by installing an application program that simulates the operation of the
console 1000 in the personal computer 1106, 2106, The operations can be performed on these
personal computers. In addition, these personal computers do not necessarily have to be
09-05-2019
21
connected to the console 1000 or the engine 2000.
[0066]
However, when the personal computer is not connected to the console 1000 or the like, it is not
possible to actually connect the units 2200 to 2400 etc. to the personal computer, so these units
have various parameters as virtual units and virtual cards. It will be set.
[0067]
2.2.
Program Details 2.2.1.
Main Routine (FIG. 5) Next, the details of a program for realizing the above-described outline
operation will be described with reference to FIGS. Although this program is described as
operating on the console 1000 for convenience of explanation, if the personal computer 2106 is
a master of the engine 2000, it can also operate on the personal computer 2106. In other words,
the program runs on a device that becomes the master of the engine 2000.
[0068]
When the console 1000 is powered on, a main routine shown in FIG. 5 is executed. When the
process proceeds to step SP2 in the figure, predetermined initialization is performed. Next, when
the process proceeds to step SP4, each part in the digital mixing system is scanned, and an event
that has occurred is detected. The "event" mentioned here includes an event of a MIDI signal,
automatic scene switching, panel operation by the operator, and connection or disconnection of
units 2200 to 2400 and the like.
[0069]
Next, when the process proceeds to step SP6, it is determined in step SP4 whether or not any
event has occurred. If the determination is "NO" here, the process returns to step SP4 and the
event detection is repeated. On the other hand, if it is determined as "YES", the process proceeds
to step SP8, and a process corresponding to the detected event is performed. Hereinafter, the
09-05-2019
22
contents of various events and processing according to them will be described.
[0070]
2.2.2.
Connection detection of a new unit (FIG. 6) (1) When connection of the new unit to the engine
2000 is detected in step SP4 of the connection destination to the terminal in the "Blank" state,
step SP6 in FIG. The subroutine shown in is called. When this subroutine is called, the terminal
number TN of the input / output terminal for which the new connection has been confirmed is
passed to the subroutine. As for the terminal number TN, values 10 to 9 are sequentially
assigned to ten input terminals, and values 10 to 15 are sequentially assigned to six
output terminals.
[0071]
In FIG. 6, when the process proceeds to step SP20, the unit type UT of the unit related to the
terminal number TN is determined. The unit type UT is a unique value assigned to each model
number of the unit. A plurality of pins are provided on the connection terminal of each unit, but
some of these pins are used as pins for unit detection. That is, some of the pins are strapped to
the ground level, and the type of unit UT is immediately determined by this mode.
[0072]
Next, when the process proceeds to step SP22, the type of the mounted card is inquired to the
unit of the terminal number TN. In this unit, when this inquiry is received, card types CT1 to CT8
of the cards mounted in the first to eighth slots are returned to the console 1000. Note that the
values of the card types CT1 to CT8 are unique values assigned to each model number of the
card.
[0073]
Next, when the process proceeds to step SP24, it is determined whether the flag VUF (TN) is "1".
The flag VUF (TN) is a flag indicating whether or not the unit corresponding to the terminal
09-05-2019
23
number TN is a virtual unit, and "1" indicates that the unit is a virtual unit. If the determination is
"NO" here, the process proceeds to step SP30.
[0074]
In this state, a new unit is connected to the input / output terminal that was not connected at all,
and no virtual unit is assigned to that input / output terminal, so the input / output terminal is in
the Blank state. It will have been. In step SP30, the value of the unit type UT is set as the
variable UT (TN). The variable UT (TN) is a variable that indicates "a unit type UT of a unit
connected to the input / output terminal of the terminal number TN".
[0075]
In step SP30, the flag VUF (TN) is set to "0". This is because the real unit is connected to the
terminal number TN. Further, the card type CTi (i = 1 to 8) is set as the value of the variable CTi
(TN) (where i = 1 to 8). Note that the variable CTi (TN) is a variable that indicates "the type of
card inserted in the ith slot of the unit connected to the input / output terminal of the terminal
number TN".
[0076]
Furthermore, here, the flag VCFi (TN) (i = 1 to 8) is set to "0". The flag VCFi (TN) is a flag
indicating whether the card inserted in the i-th slot of the unit connected to the input / output
terminal of the terminal number TN is a virtual card or not, and "1" is Indicates that it is a virtual
card. As described above, since the input / output terminal of the terminal number TN is
originally in the Blank state, it is possible to reflect all the actual card states as the real card
states. Thus, the processing of this routine ends. Therefore, the setting of various parameters and
the like thereafter are executed based on the contents of the real unit and real card set in step
SP30.
[0077]
By the way, in FIGS. 8 to 27, etc., it has been described that the screen display of the display unit
1002 is automatically switched depending on the connection state of various units, etc. However,
the connection states of various units are actually The determination is made by referring to the
09-05-2019
24
above-described virtual unit flag VUF (TN), unit type UT (TN), card type CTi (TN), virtual card flag
VCFi (TN), and the like.
[0078]
(2)
If the virtual unit is set for the unit connection terminal number TN inconsistent with the virtual
state, "YES" is determined in step SP24, and the process proceeds to step SP26.
Here, it is determined whether the variable UT (TN), that is, the terminal number TN of the
original virtual unit is equal to the terminal number TN of the real unit actually connected.
[0079]
If the two are different, it is determined as "NO", and the process proceeds to step SP28. Here, a
predetermined conflict unit warning window is displayed on the display 1002. The contents of
this window are similar to the exit warning window 550 (see FIG. 15). That is, the operator is
warned that the set virtual unit and the real unit are different, and the operator can indicate
whether the terminal number TN is to be left as the state of the original virtual unit. And two
buttons "NO" are displayed.
[0080]
When the operator clicks the "YES" button, the processing of this routine ends. That is, the
setting contents related to the terminal number TN are left as they are in the state of the virtual
unit. In such a state, it is displayed on the display 1002 whether the terminal number TN is
merely left as a virtual unit or whether it is left as a virtual unit inconsistent with a real unit.
Good.
[0081]
On the other hand, if the operator clicks the "NO" button in step SP28, the process proceeds to
09-05-2019
25
step SP30. That is, the previously set virtual unit state is ignored, and various parameters are set
based on the contents of the real unit and the real card.
[0082]
(3)
If the unit type UT of the unit newly connected to the unit connection terminal number TN
matching the virtual state matches the unit type UT (TN) of the virtual unit, it is determined as
"YES" in step SP26 and the processing Proceed to step SP32. Here, the virtual unit flag VUF (TN)
is set to "0". Next, when the process proceeds to step SP34, "1" is substituted for a variable i for
counting slots.
[0083]
Next, when the process proceeds to step SP36, it is determined whether the card type CTi (TN)
set as the virtual card is equal to the card type CTi of the real card. Here, if the two match, it is
determined as "YES", and the process proceeds to step SP38. Here, the virtual card flag VCFi (TN)
relating to the card is set to "0". That is, since a card of the same model number as the card
originally set as a virtual card was actually inserted, the flag VCFi (TN) is changed to a real card
by setting "0".
[0084]
On the other hand, if the card type CTi (TN) of the two and the card type CTi do not match, "NO"
is determined in step SP36, and the process proceeds to step SP44. Here, the conflict card
warning window is displayed on the display unit 1002 with the same content as the conflict unit
warning window described above in step SP28, and the operator determines whether the card is
left as the original virtual card status or not. Two buttons of "YES" and "NO" are displayed so that
can indicate.
[0085]
If the operator clicks the "YES" button, the process proceeds to step SP46, where the virtual card
09-05-2019
26
flag VCFi (TN) is set to "1". Thus, in the present embodiment, even if the unit itself is a real unit,
individual cards set here can be set as virtual cards. Even in such a state, it is displayed on the
display 1002 whether the virtual card is simply set as a virtual card or whether it is left as a
virtual card inconsistent with a real card. Good.
[0086]
On the other hand, when the operator clicks the "NO" button in the conflict card warning window
(step SP44), the process proceeds to step SP48. Here, the card type CTi of the real card is set as
the contents of the card type CTi (TN). In addition, the virtual card flag VCFi (TN) related to the
card is set to "0". Next, when the process proceeds to step SP50, the setting of the card is cleared
to a predetermined initial state. For example, the gain is narrowed to minimize the card.
[0087]
As described above, when the process of steps SP36 to SP38 or SP44 to SP50 ends, the process
proceeds to step SP40. Here, a variable i for counting slots is incremented by "1". Next, when the
process proceeds to step SP42, it is determined whether or not the variable i is "9" or more. Here,
when the determination is "YES", the processing of this routine ends, whereas when the
determination is "NO", the processing returns to step SP36. As a result, after the setting process
of steps SP36 to SP38 or SP44 to SP50 is executed for all slots of i = 1 to 8, the process of this
routine ends.
[0088]
2.2.3.
Unit Detachment Detection (FIG. 7A) When the unit detachment is detected in step SP4 of the
main routine, the subroutine shown in FIG. 7A is called in step SP6. Also in this case, the terminal
number TN of the input / output terminal from which the unit has been released is passed to the
subroutine. In the figure, when the process proceeds to step SP70, it is detected whether or not
the virtual unit flag VUF (TN) is "0". If the determination is "NO" here, the processing of this
routine ends immediately. In such a case, a unit different from the unit actually connected is just
set as a virtual unit. Therefore, even if the unit actually connected is disconnected, there is no
need to particularly modify the parameters.
09-05-2019
27
[0089]
On the other hand, if NO in step SP70, the process proceeds to step SP72. Here, the
detachment warning window 550 (see FIG. 15) described above is displayed on the display 1002.
Here, if button 552 is clicked (ie, a unit which has left the group is left as a virtual unit), the
process proceeds to step SP74. Here, the virtual unit flag VUF (TN) is set to 1 , and the virtual
card flag VCFi (TN) (i = 1 to 8) is set to 1 for all slots of the virtual unit. Be done.
[0090]
On the other hand, when the button 554 is clicked in step SP72 (the detachment warning
window 550) (that is, in the case of deleting the detached unit), the process proceeds to step
SP76. Here, the unit type UT (TN) is set to 0 (where 0 represents Blank ), and the
virtual unit flag VUF (TN) is set to 0 . This is because it indicates a real state in the sense of
"is blank".
[0091]
In step SP72, the card type CTi (TN) is further set to 0 ( 0 represents Blank ) for
cards with i = 1 to 8 and the virtual card flag VCFi (TN) is set. It is set to "0". Next, when the
process proceeds to step SP78, all setting contents of the virtual card related to the terminal
number TN are cleared (returned to the initial state). Thus, the processing of this routine ends.

Setting up the digital mixing system 2.3.1. Simulation on Personal Computer Next, the outline of
the work performed by the worker when setting the digital mixing system of this embodiment
will be described with reference to FIGS. 7 (b) and 7 (c). First, the worker prepares an audio
system diagram of the entire concert hall, and registers necessary units and cards as virtual units
and virtual cards on the application program on the personal computer 1106 (step SP80).
Although this setting operation may be performed using the console 1000, the console 1000 is
heavy, and since the actual product may be being transported or used in other applications, it is

usually personal. The setting operation is performed by simulation on the computer 1106.
[0093]
Next, the settings of the input patch unit 112 and the output patch unit 134, that is, the
correspondence between physical channels and logical channels in each virtual unit and virtual
card, are displayed in the input patch display / setting window 600 and the like. Set using the
patch display / setting window (not shown). Then, for the microphone level input card, settings
such as microphone gain and phantom power are performed according to the type of
microphone (step SP 82). When the above-described work is completed, the setting contents are
stored as a library in a non-volatile memory (in a personal computer, a hard disk etc.) (step
SP84).
[0094]
2.3.2.
Setting Operation at the Site Next, operations performed mainly in a concert hall or the like will
be described with reference to FIG. 7 (c). First, the console 1000 is installed at a predetermined
position, the console 1000 and the engine 2000 are connected, the power of both is turned on,
and then the contents of the library are loaded from the personal computer 1106 to the console
1000 (step SP90). Thereafter, a worker connects various units to the engine 2000, and the
virtual unit is converted to a real unit each time the correct unit is connected. In addition, when
an incorrect unit is connected, a contradiction occurs to the virtual unit, and this is immediately
warned (SP 92). Of course, depending on the circumstances, as described above, the unit actually
connected can be used as it is.
[0095]
And if all units are completely connected, all virtual units should be changed to real units. After
connecting the input / output units in this way, a microphone, an amplifier, etc. will be connected
to the terminals of the card in each unit. Since the gains to be set to these microphones,
amplifiers, etc. are also set in advance, the microphones, amplifiers, etc. can be immediately used
at an appropriate level if connected (SP 94).

As described above, according to the present embodiment, even when the actual product of the
console 1000 or the engine 2000 is being transported, or is being used for another application,
various parameters can be set by the personal computer alone. . The set parameters can be
instantly reflected on the console 1000 or the like when the console 1000 or the like becomes
available. This makes it possible to complete the setting operation of the digital mixing system in
a very short time at a site such as a concert hall or the like where the audio equipment is
installed.

Modifications The present invention is not limited to the above-described embodiment, and
various modifications can be made, for example, as follows. (1)In each of the above embodiments,
the simulation of the digital mixing system is performed by an application program operating on
a personal computer, but only this application program is stored in a recording medium such as a
CD-ROM or floppy (registered trademark) disk. It can also be distributed or through a
transmission line.
[0098]
(2)
In the input patch display / setting window 600 of the above embodiment, as a method of
automatically setting the correspondence between the logical channel and the physical channel,
clicking the AUTO SETUP button 610 and the circle marks on the matrix are on a straight
line. It was limited to arranging. However, a plurality of types of this automatic setting may be
provided so that the operator can arbitrarily select.
[0099]
As described above, when the type of the new unit matches the type of the virtual unit and the
configuration for the virtual unit is inherited to the new unit, the unit is not yet complete. Various
settings can be made even in the connected state, and these settings can be completed quickly
when each unit is actually connected.

In addition, according to the configuration in which the first and second options are presented to
the operator when the unit leaves, it is possible to leave the setting contents of the unit not
connected according to the intention of the operator as it is. When the unit is connected again,
the setting of the unit can be completed quickly.
