indicated by the selection parameter SP of the channel assigned to the channel strip i of the
selection group SG among the parameters stored in the RAM. . Then, when display relating to the
parameter is performed on the touch panel in step S41, the display content (such as the rotation
angle of the knob) is updated, and the knob (i) operation event is ended.
[0030]
Next, FIG. 9 shows a flowchart of knob (p) operation event processing in the selection ch
operation unit 50 executed in the digital mixer 1 according to the present invention. It is
activated when any of the switch knob operators in the selection ch operation unit 50 is rotated,
and the operation value of the knob manipulator is written to the RAM 12 as the current value of
the parameter P (p, SC) in step S50. . The parameter P (p, SC) is a parameter corresponding to the
p-th switch knob operator with the switch operation in the selected channel SC selected by the
ON operation of the SEL key 61. Here, each knob operator provided in the selection channel
operation unit 50 corresponds to one of a plurality of parameters for controlling the input
channel or the output channel, and the number p of the knob operators is simultaneously
determined. , Or a number indicating one parameter of the input channel or the output channel.
Then, the display screen of the touch panel 101 is updated in step S51, and the display
corresponding to the parameter P (p, SC) in the channel strip section 102 of the displayed
channel strip screen is updated, and knob (p) operation event processing Ends.
[0031]
Next, FIG. 10 shows a flowchart of knob (p) on operation event processing in the selection
channel operation unit 50 executed in the digital mixer 1 according to the present invention. The
switch is activated when any of the switch knob operators in the selection ch operation unit 50 is
operated in the axial direction and turned on, and the number p of the p-th switch knob knob
that is turned on in step S60 is the selection parameter It is written to the RAM 12 as the current
value of SP. That is, the parameter indicated by the number p of the turned-on knob operator is
assigned to the encoder 60 of each channel strip in the assignment channel strip unit 51. Then,
in step S61, the cursor in the ch strip unit 102 is moved to the knob operator or block
corresponding to the parameter indicated by the selection parameter SP. Next, in step S62, it is
determined whether a pop-up screen for detailed setting of the parameter indicated by the
selection parameter SP is open. Here, if it is determined that the pop-up screen of the selection
parameter SP is not open, the process proceeds to step S63, and the pop-up screen of the
selection parameter SP is opened. If it is determined in step S62 that the pop-up screen of the
selection parameter SP is open, the process branches to step S64 to close the pop-up screen of

the selection parameter SP, and the knob (p) on operation event processing ends Do.
[0032]
An example of the cursor moved in step S61 of the knob (p) on operation event process shown in
FIG. 10 is shown in FIG. FIG. 11 shows an example in which the third (Send 3) of the send level
knob 50a with switch in the selection ch operation section 50 is turned on, and the Send 3 of
Send level section 102d in each channel strip of the channel strip section 102 is shown. The
cursor 102e is moved such that the cursor 102e is surrounded by all the operators in a row.
Here, when the i-th encoder 60-i of the assignment ch strip unit 51 is rotated, the signal of the
channel c (SG, i) corresponding to the ch strip i among the parameters of the RAM 12 is
transmitted to the third MIX bus The send level (SND_L3) when sending to is changed. That is, in
the selection parameter SP stored in the RAM 12, a value indicating the third send level (SND_L3)
is set. Then, the display of the control of Send 3 is changed to correspond to the changed value.
The upper display unit at the top of the send level unit 102d is a level meter 102b that displays
the input signal level of the second dynamics 44 as a bar graph, and the level of the threshold
102c currently set is also on the level meter 102b. Is displayed as a dashed line. Furthermore,
the display unit at the upper part is a GR meter 102 a that displays the amount of gain reduction
by the first dynamics 43 in a bar graph.
[0033]
Next, FIG. 12 shows an example of the pop-up screen opened in step S63 of the knob (p) on
operation event process shown in FIG. The pop-up screen 105 shown in FIG. 12 is a pop-up
screen when the third (Send 3) of the send level knob 50a with a switch in the selection ch
operation unit 50 is turned on, and the signal of each input channel is the third Of the send level
(SND_L3) at the time of sending to the MIX bus, and the switch P.P. of the pre / post (P.P3)
switch. The switch SND_ON 105 b of P 105 c and send on (SND_ON 3) is displayed on the popup screen 105 by the number of channels displayed in the ch strip unit 102. In pop-up screen
105, pre / post switch P.P. When the display of P 105 c and send switch SND_ON 105 b is
clicked by a pointing device such as a mouse, the on / off state can be reversed. The hatched pre
/ post switch P.I. P105c and send switch SND_ON 105b indicate that they have been turned on.
With the pop-up screen 105, parameters not displayed on the ch strip unit 102 can also be
displayed on the touch panel 101.

Next, another example of the cursor moved at step S61 of the knob (p) on operation event
process shown in FIG. 10 is shown in FIG. FIG. 13 shows an example when one of the second
dynamics knobs 50d with a switch in the selection channel operation unit 50 is turned on, and
the block of the level meter 102b in the channel strip unit 102 is surrounded by the cursor 102e.
Become. When the on-operated operator is the threshold knob operator, when the encoder 60-i
of the ch strip i of the assigned ch strip unit 51 is rotated, the channel corresponding to the ch
strip i among the parameters of the RAM 12 The value of the second dynamics 44 threshold
value of c (SG, i) is changed. Then, the display of the threshold 102c of the ch strip i is changed
to correspond to the changed value. When the on-operated operator is a rate knob operator, the
value of the second dynamics rate of the channel c (SG, i) among the parameters of the RAM 12
is similarly changed, but FIG. Since the second dynamics rate display is not shown in the drawing,
the display is not updated.

In the present invention described above, although the number of channels in the input channel
section 33 is 32 channels, it can be any number of channels. In addition, in the G selection
operation unit 52, a group newly set by the user can be registered. In this case, a new group can
be created by attaching the expansion card to the digital mixer 1. Although the example in which
the ch strip unit 102 and the channel operation unit are displayed on the touch panel has been
described with reference to FIG. 6, any screen can be displayed on the touch panel, and the
present invention is not limited to this example. For example, instead of the ch strip unit 102, it is
possible to display a setup screen for setting up the system of the digital mixer, a monitor screen
for setting the monitor function, a scene memory screen for managing the scene memory, and
the like. Furthermore, the display of the channel operation unit of the touch panel may be
eliminated, and instead, an indicator may be provided on the panel to indicate the current value
in correspondence with each operation element of the selected ch operation unit. Furthermore,
although the display means in the embodiment is a touch screen (touch panel), it may be
changed to a display such as a liquid crystal having no function of detecting a touch on the
screen.
