thereby determine a current operation mode of the fader

If the fader operators 36, 37 are operating in the ordinary
mode (YES determination at step S4), the LED 40 of the
currently-operating bus selection sWitch 39 is deilluminated
at step S5, and the LED 40 of the above-mentioned operated
50
bus selection sWitch 39 is sWitched to the illuminated state at
55
as an object of operation to be performed by the SOF function.
First, at step S17-S18, the object of operation to be per
formed by each of the individual fader operators 36 in the
input channel section 34 is sWitched to the “send level”
parameter for the mixing bus set as the object of operation to
60
be performed by the SOF function. Namely, the “send level”
parameters (i.e., parameters set by the send level adjustment
sections 24 of FIG. 2) for the mixing bus, currently set as the
object of operation to be performed by the SOF function, are
allocated as the object of operation to be performed by the
step S6, and a “send level” parameter, Which is to be applied
to the mixing bus corresponding to the operated bus selection
sWitch 39, of the channel currently allocated to the selected
channel section 32 is allocated to the selected send level
operator 38 at step S7. In this Way, the object of operation to
be performed by the selected send level operator 38 can be
sWitched to the mixing bus corresponding to the operated bus
selection sWitch 39.
If, on the other hand, the fader operators 36, 37 are oper
ating in the SOF mode (NO determination at step S4), it
means that the LED 40 of the currently-operating bus selec
tion sWitch 39 is in the blinked state. Thus, the LED 40 of the
65
individual fader operators 36. Then, for the mixing bus cur
rently set as the object of operation to be performed by the
SOF function, current settings of the send levels of the indi
vidual input channels 23 are read out, at step S18, from the
current memory area (?ash memory 2 or RAM 3), and the

operating knobs of the individual fader operators 36 are set, at
tion 35 is sWitched to a parameter that Was being set prior to
step S19, to positions corresponding to the read-out current
settings of the send levels of the individual input channels 23.
Because the fader operators 36 correspond to the electric
faders 8 (FIG. 1) as noted above, the operating knobs of the
individual fader operators 36 are automatically moved
through motor drive control by the CPU 1, in response to the
sWitching of the function allocated to the fader operators 36,
to positions corresponding to the read-out current settings of
the start of the SOF function. Namely, the parameter (nor
mally, output level of the stereo master channel) that Was
being set prior to the start of the SOF function is allocated, at
step S26, as the object of operation to be performed by the
fader operator 37 in the stereo master section 35. Then, the
current setting of the parameter in question is read out, at step
S27, from the current memory area (?ash memory 2 or RAM
3), and the operating knob of the fader operator 37 of the
the send levels. As explained above in relation to FIG. 3, a
stereo master section 35 is set, at step S28, to a position
plurality of (32 in the instant embodiment) channel strips are
provided in the input channel section 34, and one fader opera
tor 36 is provided in each of the plurality of channel strips.
Thus, at steps S17-S18, “send level” parameters from the
input channels, corresponding to the individual channel
strips, to the mixing bus, currently set as the object of opera
corresponding to the read-out current setting.
Thus, at steps S23-S28, the SOF function is ended so that
the operation in the ordinary mode is resumed, and the tone
tion to be performed by the SOF function, are allocated to the
individual ones of the 32 fader operators 36, but also move
ment control is performed on the operating knobs of the
individual fader operators 36.
volume levels of the individual input channels 23 can be
adjusted by use of the fader operators 36 of the input channel
section 34 While the allocated parameter (normally, stereo
master output level) can be adjusted by use of the fader
operator 37 of the stereo master section 35.

20
Next, at steps S20-S23, the object of operation to be per
formed by the fader operator 37 in the stereo master section
35 is sWitched to a “send level” parameter for the mixing bus
set as the object of operation to be performed by the SOF
function. Namely, at step S20, an “output level” parameter
25
(i.e., parameter set by the mixed output adjustment section
27) of the mixing channel 26, corresponding to the mixing
bus that corresponds to the bus selection sWitch 39 operated
by the user, is allocated as the object of operation to be
performed by the fader operator 37 in the stereo master sec
tion 35 (see FIG. 2). Then, the current setting of the output
level of the mixing channel 26 is read out, at step S21, from
30
operator 37 of the stereo master section 35.
FIG. 7 is a ?oW chart shoWing an example operational
sequence of the SOF mode ending process started at step S15
by the user, an operated amount of the operated fader operator
36 or 37 is detected at step S29. Then, the parameter value
currently allocated to the operated fader operator 36 or 37
(i.e., value currently stored in the current memory area) is
changed in accordance With the detected operated amounts
and the thus-changed parameter value is re?ected in the DSP
4 (step S30). Thus, With the SOF function, the send level for
the mixing bus set as the object of operation can be changed
in response to operation of the parameter value 36, or the
output level of the mixing channel 26 corresponding to the
mixing bus set as the object of operation can be changed by
the current memory area (?ash memory 2 or RAM 3), and the
operating knob of the fader operator 37 is set, at step S22, to
a position corresponding to the read-out current setting of the
output level. Because the fader operator 37 too corresponds to
one of the electric faders 8 (FIG. 1) as noted above, the
operating knob of the fader operator 37 is automatically
moved, through motor drive control by the CPU 1, to the
position corresponding to the read-out current setting of the
output level.
Thus, at steps S16-S22, the SOF function is started, and the
send levels to be applied the mixing bus currently set as the
object of operation can be adjusted by use of the fader opera
tors 36 of the input channel section 34 While the output level
of the mixing channel 26 corresponding to the mixing bus set
as the object of operation can be adjusted by use of the fader
sequence of a parameter setting process performed in
response to operation of any one of the fader operators 36 and
37. Once any one of the fader operators 36 and 37 is operated
use of the fader operator 37 of the stereo master section 35.

According to the instant embodiment, as having been
described above, the operation mode of the fader operators
can be sWitched to the SOF mode by the user depressing a
particular bus selection sWitch 39 currently operating in the
ordinary mode (i.e., bus selection sWitch 39 of Which the LED
40
45
40 Was in the illuminated state immediately before the depres
sion or operation). Further, in the SOF mode, a particular
mixing bus to be set as the object of operation to be performed
by the SOF function can be selected by means of the 16 bus
selection sWitches 39 of the mixing bus selection section 33.
The LED 40 of the bus selection sWitch 39, selected as the
object of operation to be performed by the SOF function, is
sWitched to the blinked state. By the user further depressing
the bus selection sWitch 39 operating in the SOF mode (i.e.,
bus selection sWitch 39 of Which the LED 40 Was in the
50
blinked state), the operation mode of the fader operators 36,
above. First, at steps S23-S25, the object of operation to be
performed by the individual fader operators 36 in the input
37 can be sWitched from the SOF mode to the ordinary mode.
Further, the selection of a mixing bus as an object of operation
channel section 34 is sWitched to “tone volume level param
in the SOF mode can be performed in a manner that corre
eters” of the individual input channels. Namely, “tone volume
level parameters” of the individual input channels are allo
cated as the object of operation to be performed by the indi
vidual fader operators 36. Then, the current settings of the
tone volume levels of the individual input channels 23 are
read out, at step S24, from the current memory area (?ash
memory 2 or RAM 3), and the operating knobs of the indi
vidual fader operators 36 are set, at step S25, to positions
corresponding to the read-out current settings of the tone
volume levels of the individual input channels 23. The opera
tions at steps S23-S25 too are performed for each of the
plurality of fader operators 36 in the input channel strips 34.

performed by the fader operator 37 in the stereo master sec

in the SOF mode and the bus selection sWitch 39 can be easily
identi?ed, because the existing bus selection sWitches 39 are
used for this purpose.
To cancel (deactivate or turn off) the SOF function, for
example, in a case Where, in the ordinary mode (Where the
SOF function is OFF), another mixing bus than the mixing
bus last (i.e., most recently) set as an object of operation to be
performed by the SOF function is allocated as an object of
operation to be performed by the selected send level operator
38, the user only has to depress tWice in succession the bus

SOF function) corresponding to the other mixing bus. The
