equalizer panel 100 of the graphic equalizer shown in FIG. 10 is an equalizer panel when the
frequency band is divided into four as shown in FIG. In the frequency band divided into four, the
lowermost frequency band is BAND LOW, and the uppermost frequency band is BAND HIGH, and
the frequency band in between is divided into BAND1 and BAND2.
[0003]
In BAND LOW, a volume F101 for adjusting the cutoff frequency of a high pass filter (HPF), a
volume G101 for adjusting the gain of the HPF, and a switch SW101 for switching the filter
characteristic of the HPF are provided. A knob is attached to each of the volume F101 and the
volume G101. Also, the filter characteristics switched by the changeover switch SW101 are the
HP1 characteristic and the HP2 characteristic shown in FIG. 11, and as shown in FIG. 11, the
HP1 characteristic is the gain where the gain in the lowest region is adjusted by the volume
G101, the HP2 characteristic Is a frequency characteristic that is attenuated as the frequency
decreases. The cutoff frequency in the HP1 characteristic or the HP2 characteristic selected by
the changeover switch SW101 can be adjusted within the frequency band of BAND LOW by
rotating the knob of the volume F101 as shown in FIG. The gain in the lowest region of the
characteristics can be adjusted by rotating the knob of the volume G101 as shown in FIG.
[0004]
The BAND 1 is provided with a volume F102 for adjusting the center frequency of the band
rejection filter (BRF), a volume G102 for adjusting the gain of the BRF, and a volume Q102 for
adjusting the selectivity (Q) of the BRF. A knob is attached to each of the volume F102, the
volume G102, and the volume Q102. The BRF is a filter that can increase or attenuate the gain of
a predetermined band centered on a desired frequency as shown in FIG. As shown in FIG. 11, by
rotating the knob of volume F102, the center frequency of this BRF can be adjusted within the
frequency band of BAND 1, and the steepness (ie, bandwidth) of the attenuation characteristic of
BRF can be adjusted. The selectivity (Q) shown can be adjusted by rotating the knob of volume
Q102, and the gain at the center frequency of BRF can be adjusted by rotating the knob of
volume G102.
[0005]
In BAND 2, as in BAND 1, a volume F103 for adjusting the center frequency of the band rejection

selectivity (Q) shown can be adjusted by rotating the knob of volume Q103, and the gain at the
center frequency of BRF can be adjusted by rotating the knob of volume G103.
[0006]
The BAND HIGH is provided with a volume F104 for adjusting the cutoff frequency of a low pass
filter (LPF), a volume G104 for adjusting the gain of the LPF, and a switch SW104 for switching
the filter characteristics of the LPF. A knob is attached to each of the volume F104 and the
volume G104. The filter characteristics switched by the switch SW104 are the LP1 characteristic
and the LP2 characteristic shown in FIG. 11. The LP1 characteristic is the gain in which the gain
in the highest region is adjusted by the volume G104, and the LP2 characteristic becomes as the
frequency increases. It is considered to be a frequency characteristic to be attenuated. The cutoff
frequency in the LP1 characteristic or the LP2 characteristic selected by the changeover switch
SW104 can be adjusted within the frequency band of BAND HIGH by turning the knob of the
volume F104, and the highest gain in the selected LP1 characteristic is obtained. Adjustment can
be made by rotating the knob of the volume G104.
[0007]
By the way, recently, hardware has been replaced by software, and the graphic equalizer is also
an exception, and a software graphic equalizer is provided. In such software graphic equalizer,
adjustment of the graphic equalizer is performed using a graphical user interface (GUI: Graphical
User Interface). Specifically, by displaying an equalizer panel as shown in FIG. 10 on the display
and rotating the knob of each volume using a pointing device, as shown in FIG. I am making
adjustments. The displayed equalizer panel is the same as the design of the panel surface (such
as the area and volume knob arrangement) in the same way as the design of the hardware panel
surface so that the user who used the hardware graphic equalizer can easily use it. I am trying to

In the graphic equalizers shown in FIG. 10 and FIG. 11, the number of band rejection filters is
two, and only provided in BAND 1 and BAND 2. As a graphic equalizer, three or more band
rejection filters may be required. In this case, it is conceivable to increase the number of band
rejection filters by increasing the number of divisions of the frequency band. However, if the
number of divisions in the frequency band is increased, the equalizer panel must be provided
with a knob for adjusting the characteristics of the band rejection filter in the increased
frequency band, and the panel surface design is designed with the hardware panel surface
design. There is a problem that it is impossible to do the same.
[0009]
Therefore, an object of the present invention is to provide a parameter setting device in which
the display area for that purpose does not increase as much as possible even if the number of
parameters that can be set using a GUI is increased.

operation element in which the variable knob and the concentric circle are arranged, and setting
parameters by rotating control of this switching knob and continuous variable knob As a result, it
becomes possible to set an increased parameter without increasing the display area.

knob rotating within a predetermined angle range so as to vary the continuously variable
parameter is displayed concentrically is displayed, and this switching knob and the continuous
variable are displayed. This was realized by setting parameters by controlling rotation of the
knob.

equalizer parameters using a GUI. An image of volume control is displayed on the display unit 15.
This volume knob is displayed so as to rotate according to the operation when operated using the
GUI. The sound source unit 17 generates tone waveform data based on the control of the CPU
10, and performs processing such as applying an effect to the tone waveform data. Further, it is
possible to perform gain adjustment and the like for each of several frequency bands of the tone

downloaded from the external device 20 to the tone generator 1. The downloaded program or
data is stored in the RAM 11 or the like. These units are connected to the communication bus 21.
[0015]
When performing gain adjustment or the like for each frequency band divided into several parts
by the graphic equalizer, the CPU 10 executes a parameter setting program. At this time, an
example of the equalizer panel 30 of the graphic equalizer displayed on the display unit 15 is
shown in FIG. 2, and an example of the frequency characteristic of the gain that can be adjusted
by the graphic equalizer is shown in FIG. Like the equalizer panel 100 of the hardware shown in
FIG. 10, the equalizer panel 30 of the graphic equalizer shown in FIG. 2 is an equalizer panel
when the frequency band is divided into four as shown in FIG. In the frequency band divided into
four, the lowermost frequency band is BAND 1 & LOW, and the uppermost frequency band is
BAND 4 & HIGH, and the frequency band in between is divided into BAND 2 and BAND 3.
[0016]
In BAND 1 & LOW, volume F1 adjusts the cutoff frequency of the high pass filter (HPF), volume
G1 adjusts the gain of HPF, and the filter characteristics of HPF while switching the band
rejection filter (BRF) A dual volume SQ1 is provided to adjust the selectivity (Q) of BRF. A knob is
attached to each of the volume F1 and the volume G1, and a continuously variable knob is
attached to the inside of the double volume SQ1 and a shape switching knob is attached
concentrically to the outside. The filter characteristics can be selected by rotating the shape
08-05-2019

switching knob of this dual volume SQ1, and the selectable filter characteristics are HP1
characteristics, HP2 characteristics and BR (band rejection) characteristics shown in FIG. Is
displayed at the bottom of the dual volume SQ1. The frequency characteristic shown by A in FIG.
3 is a flat frequency characteristic before adjustment by the graphic equalizer. The HP1
characteristic is a gain whose gain in the lowest band is adjusted by the volume G1, the HP2
characteristic is a frequency characteristic that is attenuated as the frequency decreases, and the
BR (band rejection) characteristic is a predetermined one centered on a desired frequency. It is
considered as a band rejection filter (BRF) that can increase or attenuate the gain of the B band.
[0017]
Also, the cutoff frequency in the HP1 characteristic or HP2 characteristic selected by rotating the
shape switching knob of the dual volume SQ1 can be adjusted within the frequency band of
BAND 1 & LOW by rotating the knob of the volume F1. The gain of the lowest band in the
selected HP1 characteristic can be adjusted by rotating the knob of the volume G1. Furthermore,
when BR (band rejection) is selected by rotating the shape switching knob of the dual volume
SQ1, by rotating the knob of the volume F1 at the center frequency in the BRF, within the
frequency band of BAND 1 & LOW. The gain in the BRF can be adjusted by rotating the knob of
the volume G1, and further, by rotating the continuous variable knob of the dual volume SQ1, the
steepness of the attenuation characteristic of the BRF (ie, , Bandwidth) can be adjusted (Q). Thus,
in BAND 1 & LOW, in addition to HPF, BRF is additionally provided, and it combines volumes F1
and G1 and its knob to adjust the filter characteristic of each filter, and continuously variable
knob and shape switch knob By making the double volume SQ1 concentrically provided, it is
possible to adjust the filter characteristics of the added BRF without changing the design of the
panel surface as much as possible and increasing the display area.
[0018]
The BAND 2 is provided with a volume F2 for adjusting the center frequency of the band
rejection filter (BRF), a volume G2 for adjusting the gain of the BRF, and a volume Q2 for
adjusting the selectivity (Q) of the BRF. A knob is attached to each of the volume F2, the volume
G2 and the volume Q2. BRF is a filter that can increase or attenuate the gain of a predetermined
band centered on a desired frequency as shown in FIG. As shown in FIG. 3, the center frequency
of this BRF can be adjusted by rotating the knob of volume F2 within the frequency band of
BAND 2, and indicates the steepness (that is, the bandwidth) of the attenuation characteristic of
BRF. The selectivity (Q) can be adjusted by rotating the knob of volume Q2, and the gain of BRF
can be adjusted by rotating the knob of volume G2.
08-05-2019

[0019]
Like BAND 2, BAND 3 is provided with volume F3 for adjusting the center frequency of BRF,
volume G3 for adjusting the gain of BRF, and volume Q3 for adjusting the selectivity (Q) of BRF. A
knob is attached to each of the volume F3, the volume G3 and the volume Q3. As shown in FIG. 3,
the center frequency of this BRF can be adjusted by rotating the knob of volume F3 within the
frequency band of BAND 3, and indicates the steepness (ie, bandwidth) of the attenuation
characteristic of BRF. The selectivity (Q) can be adjusted by rotating the knob of volume Q3, and
the gain of BRF can be adjusted by rotating the knob of volume G3.
[0020]
In BAND 4 & HIGH, the volume F4 adjusts the cutoff frequency of the low-pass filter (LPF), the
volume G4 adjusts the gain of the LPF, and the filter characteristics of the LPF as well as the
band rejection filter (BRF) is selected. A dual volume SQ4 is provided to adjust the selectivity (Q)
of BRF. A knob is attached to each of the volume F4 and the volume G4, and a continuously
variable knob is attached to the inner side of the double volume SQ4 and a shape switching knob
is attached to the outer side concentrically. The filter characteristics can be selected by rotating
the shape switching knob of this dual volume SQ4, and the selectable filter characteristics are
considered as LP1 characteristics, LP2 characteristics and BR (band rejection) characteristics
shown in FIG. Is displayed at the bottom of the dual volume SQ4. The LP1 characteristic is a gain
whose maximum gain is adjusted by the volume G4, the LP2 characteristic is a frequency
characteristic that is attenuated as the frequency rises, and the BR (band rejection) characteristic
is a predetermined one centered on a desired frequency. It is considered as a band rejection filter
(BRF) that can increase or attenuate the gain of the B band.
[0021]
In addition, the cutoff frequency in the LP1 characteristic or the LP2 characteristic selected by
rotating the shape switching knob of the dual volume SQ4 can be adjusted within the frequency
band of BAND 4 & HIGH by rotating the knob of the volume F4. The gain in the selected LP1
characteristic can be adjusted by rotating the knob of the volume G4. Furthermore, when BR
(band rejection) is selected by rotating the shape switching knob of the dual volume SQ4, by
rotating the knob of the volume F4 at the center frequency in the BRF, the frequency band of
08-05-2019
8
BAND 4 & HIGH is reached. The gain in the BRF can be adjusted by rotating the knob of the
volume G4, and furthermore, the steepness of the attenuation characteristic of the BRF by
rotating the continuous variable knob of the dual volume SQ4 ( That is, the selectivity (Q)
indicating the bandwidth can be adjusted.
[0022]
Thus, in BAND 4 & HIGH, BRF is additionally provided in addition to the LPF, and it serves as
both volumes F4 and G4 for adjusting the filter characteristics of the respective filters and their
knobs, and continuously variable knob and shape switch knob Since the double volume SQ4 is
provided concentrically, it is possible to adjust the filter characteristics of the added BRF without
changing the design of the panel surface as much as possible and increasing the display area.
Therefore, in the equalizer panel 30 shown in FIG. 2, since the band rejection filter (BRF) can be
selected and set by the dual volumes SQ1 and SQ4 in BAND 1 & LOW and BAND 4 & HIGH, the
display area of the panel surface is increased. Thus, it becomes possible to obtain a graphic
equalizer having a 4-band band rejection filter from a 2-band rejection filter.
[0023]
Next, each parameter in the graphic equalizer described above can be set on the equalizer panel
30 using the GUI. Here, the parameter setting using the GUI will be described by enlarging the
dual volume SQ1 and showing it in FIG. As shown in FIG. 4, in the dual volume SQ1, the shape
switching knob 31 is attached to the outside and the continuous variable knob 32 is attached to
the inside. The shape switching knob 31 is attached to a volume (switch) capable of selecting one
of a plurality of parameters, and the parameter to be set is a shape parameter for selecting a
filter characteristic. The shape switching knob 31 is made to rotate at a predetermined angle (for
example, about 30 °), and the shape switching knob 31 is provided with a protrusion to which
the switching position indicator 31a is attached. A protrusion of the same shape is provided on
the side facing the portion 31a. An HP1 mark 33, an HP2 mark 34, and a BR mark 35 are
displayed at predetermined angles around the lower part of the shape switching knob 31, and
the shape switching knob 31 indicates a switching position to a position indicating any of these
shape marks. It rotates by a predetermined angle so that the part 31a comes. In this case, the
filter characteristic selected by the dual volume SQ1 is the filter characteristic indicated by the
shape mark indicated by the switching position indication unit 31a. In FIG. 4, the switching
position indication unit 31a indicates the HP2 mark 34, and the HP2 characteristic is selected as
the filter characteristic.
08-05-2019

[0024]
A continuous variable knob 32 located inside the shape switching knob 31 is mounted on a
volume capable of changing parameters of continuous values. Here, the parameter is a
continuous parameter that sets the selectivity (Q) in BRF. The continuous variable knob 32 can
be rotated within a predetermined angular range (for example, about 300 degrees), and when it
is rotated upward, the value of the continuous parameter becomes a median value. If it is rotated
further to the left, the value of the continuous parameter decreases and the attenuation
characteristic of BRF becomes a smooth characteristic, so that the bandwidth of BRF is
broadened, and if it is rotated to the right, the value of the continuous parameter is As the
attenuation characteristics of BRF increase and become steeper, the bandwidth of BRF becomes
narrower.
[0025]
The periphery of the dual volume SQ1 is shown hatched in FIG. 4, but the cursor can be placed
on one of the hatched areas and the shape switching knob 31 or the continuous variable knob 32
can be operated by operating the pointing device. Rotation operation can be performed. Here,
when the cursor is placed on the switching range R4 where the HP1 mark 33 shown in FIG. 4 is
located and the pointing device is clicked on, the shape switching knob 31 rotates the HP1 mark
33 to the position indicated by the switching position indicator 31a. The HP1 characteristic is
selected as the filter characteristic. When the cursor is placed on the switching range R5 where
the HP2 mark 34 is located and the pointing device is clicked on, the shape switching knob 31
rotates the HP2 mark 34 to the position indicated by the switching position indicator 31a, and
HP2 as a filter characteristic. Characteristics will be selected. Furthermore, when the cursor is
placed on the switching range R6 where the BR mark 35 is located and the pointing device is
clicked on, the shape switching knob 31 rotates the BR mark 35 to the position indicated by the
switching position indicator 31a and the band as a filter characteristic The rejection filter (BRF)
will be selected. Furthermore, the cursor is placed on the switching range R3 which is the area of
the protrusion to which the switching position indication part 31a is attached or the switching
range R7 which is the area of the protrusion opposite thereto, and the pointing device is clicked
on to make a double volume. When the angle of the cursor with respect to the central axis of SQ1
is moved (changed), the shape switching knob 31 rotates at every predetermined angle according
to the movement of the cursor, and the filter characteristic corresponding to the rotational
position is selected. . However, the shape switching knob 31 does not rotate upward beyond the
position indicating the HP1 mark 33 and the BR mark 35. As described above, it is possible to
select one of the HP1 characteristic, the HP2 characteristic, and the switching parameter of the
08-05-2019
10
band rejection filter (BRF) by the shape switching knob 31.
[0026]
Next, place the cursor on the variable range R1 which is the display area of the continuous
variable knob 32 shown in FIG. 4 and click on the pointing device to move (change) the angle of
the cursor with respect to the central axis of the dual volume SQ1. Then, the value corresponding
to the rotational position when the continuous variable knob 32 is rotated and clicked off
according to the movement of the cursor is set as the value of the continuous parameter.
Specifically, when the pointing device is clicked on, the coordinate position of the cursor is
detected, and then the coordinate position when clicked on is detected, whereby the moving
distance (rotation angle) of the cursor is calculated. The value of the continuous parameter is
updated by reflecting the value of the parameter according to the movement distance on the
value of the continuous parameter so far. Alternatively, the coordinate position of the cursor is
taken in at predetermined time intervals until the click-off, the movement distance (rotational
angle) of the cursor is calculated, and the value corresponding to the movement distance is
sequentially reflected in the parameter value that has been set. By doing this, the parameter
value may be updated to follow the movement of the cursor. In this case, by using the
information of the movement distance (rotation angle), the continuously variable knob 32 can be
rotated and displayed so as to follow the movement of the cursor.
[0027]
Furthermore, when the cursor is placed on the variable range R2 which is the outer peripheral
area of the continuous variable knob 32 shown in FIG. 4 and is the area excluding the switching
ranges R4, R5 and R6, the coordinates of the cursor are clicked. The position is detected and the
value corresponding to the coordinate position is taken as the start value of the continuous
parameter. That is, the continuous parameter value jumps to the value corresponding to the
clicked on cursor position, and the continuous variable knob 32 is also displayed so as to rotate
to the position corresponding to the coordinate position. Then, when the angle of the cursor with
respect to the central axis of the dual volume SQ1 is moved (changed) by the pointing device
which has been clicked on, the continuously variable knob 32 is rotated and clicked off according
to the movement of the cursor. A parameter value corresponding to the rotational position is set
as a continuous parameter value. Specifically, by detecting the coordinate position at the time of
click-off, the movement distance (rotational angle) of the cursor is calculated from the coordinate
position of the cursor at the time of click-on which has already been detected. The parameter
value corresponding to the movement distance is reflected on the start value of the continuous
08-05-2019
11
parameter set when the user clicks on. Alternatively, the coordinate position of the cursor is
taken in every predetermined time until the click-off, the movement distance (rotation angle) of
the cursor is sequentially calculated, and the value corresponding to the movement distance is
set as the continuous parameter value set so far The continuous parameter values may be
updated so as to follow the movement of the cursor by sequentially reflecting them. In this case,
by using the information of the movement distance (rotation angle), the continuously variable
knob 32 can be rotated and displayed so as to follow the movement of the cursor.
[0028]
In this way, the area around the dual volume SQ1 is divided into a plurality of areas, the cursor is
placed on any of these areas, and the pointing device is clicked on or the cursor is further moved.
The switching knob 31 and the continuous variable knob 32 can be rotated independently of
each other. Thus, when the shape switching knob 31 is independently rotated, the filter
characteristic can be switched to any one of the HP1 characteristic, the HP2 characteristic and
the BR (band rejection) characteristic. When the characteristics are selected, it is possible to
adjust the selectivity (Q) of the BRF by independently rotating the continuous variable knob 32.
[0029]
Next, FIG. 5 shows a flowchart of click-on processing that is activated when (left) click of the
mouse designated as the pointer device is turned on when the parameter setting program is
activated by the user's instruction. When the parameter setting program is activated, the
equalizer panel 30 shown in FIG. 2 is displayed on the screen of the display unit 15. On the
screen of the display unit 15 on which the equalizer panel 30 is displayed, a cursor which can be
moved using a mouse is displayed, and the current position (currently designated coordinate
position) of the cursor is recognized. Here, when the (left) click of the mouse is turned on, the
click-on process is activated, and at step S10, the coordinate position of the current cursor is
hatched in FIG. It is determined whether or not it is in the operation area. Here, if it is determined
that the cursor is in the operation area, the process proceeds to step S11, and the current
position of the cursor is included in any of the plurality of areas possessed by the dual volume
SQ1 or dual volume SQ4 to be operated To detect if it is Next, the process shifts to the processing
of the area-specific operation so as to execute the processing of the area-specific operation
corresponding to the area detected in step S12, and the click-on processing ends. If it is
determined in step S10 that the current position of the cursor is not within the operation area of
dual volume SQ1 or dual volume SQ4 shown by hatching in FIG. A process to be executed by
click-on, for example, an operation process of volumes other than the dual volume SQ1 or dual
08-05-2019
12
volume SQ4 is executed, and the click-on process is ended.
[0030]
Next, the processing of the region-specific operation transferred from step S12 of the click-on
processing will be sequentially described. First, FIG. 6 shows a flowchart of a first parameter
setting process which is shifted when the area including the current position of the cursor is
detected as the variable range R1 in step S11 of the click-on process. When the cursor is placed
on the variable range R1 and the mouse (left) click is turned on, the first parameter setting
process is activated, and the current coordinate position of the cursor immediately after the click
is held as the start position in step S20. Ru. Next, in step S21, the process waits until mouse clickoff is detected, and when mouse click-off is detected, the process proceeds to step S22. Until the
mouse is clicked off, the user moves the cursor with the mouse to determine the amount of
change of the continuous parameter. At that time, the display of the continuously variable knob is
successively changed so that the moving direction and the moving distance (rotational angle) can
be visually checked according to the moving direction and the moving distance (rotational angle)
of the cursor.
[0031]
In step S22, the current coordinate position of the cursor immediately after clicking off is
detected as the end position, and in step S23 the moving direction and movement distance of the
cursor are determined from the detected end position and the start position held in step S20. The
angle) is calculated. Next, the content calculated in step S24 is converted to the change amount
of the continuous parameter, and the change amount converted in step S25 is reflected on the
continuous parameter to update the value of the continuous parameter, and the first parameter
setting process finish. The continuity parameter in this case is the selectivity (Q) of the band
rejection filter (BRF). In steps S21 to S25, the current coordinate position of the cursor is taken in
every predetermined time until the click-off is detected, the movement distance (rotation angle)
of the cursor is sequentially calculated, and the value corresponding to the movement distance is
calculated. The continuous parameter values may be updated to follow the movement of the
cursor by sequentially reflecting the continuous parameter values that have been set up to that
point.
[0032]

Next, FIG. 7 is a flowchart of a second parameter setting process which is shifted when the area
including the current position of the cursor is detected as the switching range R3 or the
switching range R7 in step S11 of the click-on process. Show. When the cursor is placed in
switching range R3 or switching range R7 and the mouse (left) click is turned on, the second
parameter setting process is activated, and the current coordinate position of the cursor
immediately after clicking is started in step S30. Hold as position. Then, in step S31, the process
waits until mouse click-off is detected, and when mouse click-off is detected, the process
proceeds to step S32. Until the mouse is clicked off, the user moves the cursor with the mouse to
select a new option of the switching parameter. At that time, the display of the shape switching
knob is sequentially changed so that the moving direction and the moving distance (rotational
angle) can be visually checked according to the moving direction and the moving distance
(rotational angle) of the cursor.
[0033]
In step S32, it is determined whether the current coordinate position of the cursor immediately
after the click-off is within an area where any one of the options can be selected. Here, if it is
determined that one of the options can be selected, the process proceeds to step S33, and the
option associated with the area including the current coordinate position of the cursor is added
to the new switching parameter. Determined as a set value. Next, the set value determined in step
S34 is reflected on the switching parameter, and the second parameter setting process ends. If it
is determined in step S32 that the current coordinate position of the cursor is not within the area
where any of the options can be selected, the process branches to step S35 and the display of
shape switching knob is returned to the start position. The parameter setting process of 2 ends.
In this case, the switching parameter is not updated.
[0034]
Next, the third parameter setting process to be transitioned when the area including the current
position of the cursor is detected as any of the switching range R4, the switching range R5, or the
switching range R6 in step S11 of the click-on process The flow chart of is shown in FIG. When
the cursor is placed in any of switching range R4, switching range R5 or switching range R6 and
the click of the mouse (left) is turned on, the third parameter setting process is activated, and the
cursor immediately after the click is turned on in step S40. The option corresponding to the area
including the current coordinate position of is determined as a new setting value of the switching
parameter. At this time, in accordance with the moving direction and moving distance (rotational

angle) of the cursor, the display of the shape switching knob is sequentially changed so that the
moving direction and the moving distance (rotational angle) can be visually observed. Next, the
third parameter setting process ends, reflecting the setting value determined in step S41 in the
switching parameter.
[0035]
Next, FIG. 9 shows a flowchart of a fourth parameter setting process which is shifted when the
area including the current position of the cursor is detected as the variable range R2 in step S11
of the click-on process. When the cursor is placed on the variable range R2 and the mouse (left)
click is turned on, the fourth parameter setting process is activated, and the current coordinate
position of the cursor immediately after the click is held as the start position in step S51. Ru.
Next, in step S52, a value corresponding to the start position is set as the current value of the
continuous parameter, and in step S53, the display of the continuous variable knob is changed
corresponding to the value of the continuous parameter after setting. Then, the process proceeds
to step S54 and waits until mouse click-off is detected, and when mouse click-off is detected, the
process proceeds to step S55. Until the mouse is clicked off, the user moves the cursor with the
mouse to determine the amount of change of the continuous parameter. At that time, the display
of the continuously variable knob is successively changed so that the moving direction and the
moving distance (rotational angle) can be visually checked according to the moving direction and
the moving distance (rotational angle) of the cursor.
[0036]
In step S55, the current coordinate position of the cursor immediately after click-off is detected
as the end position, and in step S56 the moving direction and movement distance of the cursor
are determined from the detected end position and the start position held in step S51. The angle)
is calculated. Next, the content calculated in step S57 is converted to the change amount of the
continuous parameter, the change amount converted in step S58 is reflected on the continuous
parameter to update the value of the continuous parameter, and the fourth parameter setting
process finish. The continuity parameter in this case is the selectivity (Q) of the band rejection
filter (BRF). In steps S54 to S58, the current coordinate position of the cursor is taken in every
predetermined time until the click-off is detected, the movement distance (rotation angle) of the
cursor is sequentially calculated, and the value corresponding to the movement distance is
calculated. The continuous parameter values may be updated to follow the movement of the
cursor by sequentially reflecting the continuous parameter values that have been set up to that
point.

In the above description, the parameter set in the dual volume is the switching parameter of the
selectivity (Q) and the filter characteristic, but the present invention is not limited thereto and the
parameter set in the dual volume is set as a continuous value It may be a combination of the
parameters to be selected and the parameters to be set by selection. Alternatively, a continuous
variable knob that changes a parameter set by a continuous value may be disposed outside, and a
shape switching knob that selects a parameter may be disposed inside. Furthermore, when the
operation program is not stored in the ROM 12, the operation program or data is stored in the
hard disk or CD-ROM and read into the RAM 11, or connected to the server computer via the
communication network to connect from the server computer By downloading the control
program and data, the CPU 10 can execute the same operation as in the case where the operation
program and data are stored in the ROM 12.
[0038]
Also, when the HP1 (LP1) characteristic or the HP2 (LP2) characteristic is selected by the shape
switching knob, it is preferable to invalidate the continuous variable knob. This is because when
the HP1 (LP1) characteristic or the HP2 (LP2) characteristic is selected, there is no continuous
parameter that reflects the amount of change instructed by the continuous variable control, and
there is no meaning to reflect the amount of change. . In this case, it is determined whether the
HP1 (LP1) characteristic or the HP2 (LP2) characteristic is selected as the switching parameter
when the operation of the continuous variable knob is accepted, and if either is selected, the
continuous variable knob is selected. The amount of change may not be reflected. Furthermore,
when one of the continuous variable knobs is operated when it is selected, the display change
and the change amount are not reflected, or the operation of the continuous variable knobs
accepted when any of them is selected It may be ignored (the first parameter setting process and
the fourth parameter setting process are not activated). Although the pointing means is a mouse
or a pen in the above description, the pointing means is not limited to this and may be any
pointing means that can operate a GUI. For example, the pointing means may be configured by a
touch pad or a touch panel provided on the display unit. Furthermore, as shown in FIG. 3,
although it was set as the graphic equalizer of 4 bands, a part of frequency domain of each band
may be made to mutually overlap, and you may make it include an adjacent band. Also, the
frequency band may be divided into any number of frequency bands, not limited to four bands.
