Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parameter information setting device capable of easily setting various parameter information in an electronic musical instrument.

[0002]

2. Description of the Related Art In some electronic musical instruments, it is necessary to set various kinds of parameter information for generating musical tones. The parameter information includes, for example, parameters that define tone color and volume. Also, there are parameters and the like whose settings are changed in order to change the musical sound during performance.

As an operator for setting these parameters, one having an auxiliary operator such as a slide volume (hereinafter referred to as a slider) is known.

For example, Japanese Patent Publication No. 62-49635 discloses that
There is disclosed a device which is connected to an electronic musical instrument and sets parameter information, which includes a parameter designating switch and a slider which is an auxiliary operator (controller) on a control panel. Accordingly, the parameter to be set can be designated by the parameter designation switch, and the value of the designated parameter can be changed using the slider.

On the other hand, a display device such as a liquid crystal display device is provided,
There is a device that imitates a parameter designating switch and slider, and sets parameters using a pointing device such as a mouse.

[0006] For example, the parameter is specified by placing the mouse cursor on the part of the parameter designating switch displayed on the display and clicking (pressing and immediately releasing the mouse button provided on the mouse). Furthermore, the value of the parameter can be set by moving the mouse cursor to the slider part displayed on the display and dragging (moving the mouse while holding down the mouse button and releasing the mouse button at the target position). is there.

[0007]

By the way, among various parameters of an electronic musical instrument, there are parameters that significantly affect a musical sound (in other words, parameters having a very high sensitivity or degree of influence). For example, among the parameters of the tone color, there are some parameters in which the tone color changes drastically with a change in the value of the parameter. In addition, a specific parameter value range may differ from a possible range of the slider position (or the slider output value).
For example, there is a case in which the slider is positioned at one of 128 steps from 0 to 127, but the parameter value set by the slider is desired to be in the range of 30 to 110.

Therefore, it is conceivable that the maximum value MAX and the minimum value MIN of the range of parameter values can be designated. The maximum value MAX and the minimum value MIN may be designated by directly inputting numerical values, but there is also a method of independently designating by displaying a slider or the like on the above display and dragging the mouse.

However, among the parameters of the electronic musical instrument,
Depending on the situation, the interval (difference) between the maximum value MAX and the minimum value MIN
There is also a parameter for which you want to move in parallel with constant. If the maximum value MAX and the minimum value MIN are specified independently, it is not easy to keep their intervals constant.

An object of the present invention is to improve a parameter information setting device for electronic musical instruments. Another object of the present invention is to easily specify a range of parameters that can be set by an auxiliary operator for setting parameter information.

[0011]

SUMMARY OF THE INVENTION The present invention is an apparatus which is provided with an auxiliary operator and sets parameter information for an electronic musical instrument in accordance with the operation of the auxiliary operator, the range of possible values of the parameter information. In a parameter information setting device for an electronic musical instrument, which is capable of setting a first limit value and a second limit value that define the first limit value and a second display object for setting the first limit value.

When the start position of the instruction to move the display object by the pointing device is in the vicinity of the second display object, only the second limit value is set and changed based on the movement amount, and the display by the pointing device is performed. When the start position of the instruction to move the object is within a predetermined area between the first display object and the second display object, the first limit value and the second value are determined based on the movement amount. Means for changing the settings of these two limit values while keeping the difference between the first limit value and the second limit value constant, and keeping the difference between the first limit value and the second limit value constant. And a means for setting parameter information according to the operation of the operator.

A device for setting parameter information for an electronic musical instrument, which is a first display object for setting the first parameter information and a second display object for setting the second parameter information. And a pointing device for instructing the movement of the display object on the display screen, and the start position of the instruction to move the display object by the pointing device is in the vicinity of the first display object. Changes only the first parameter information based on the movement amount, and when the start position of the instruction to move the display object by the pointing device is in the vicinity of the second display object, the movement amount is changed to the movement amount. Based on the setting change of only the second parameter information, the start position of the instruction to move the display object by the pointing device is the same as the first display object. When it is within a predetermined area between the two display objects, both of these parameter information are kept on the basis of the movement amount while keeping the difference between the first parameter information and the second parameter information constant. And a means for changing the setting.

The first display object and the second display object are
It should be displayed so that it can be distinguished on the display screen. The auxiliary operator is, for example, a slider or a wheel.

[0014]

When the parameter information is set by the auxiliary operator such as the slider or the wheel, the value of the parameter information can always be between the first limit value and the second limit value. Specifically, even if the slider knob is moved from one end to the other, the parameter information set thereby can be kept within a predetermined limit value range.

The setting of the first and second limit values can be performed by moving the corresponding first display object and second display object with a pointing device (for example, drag operation using a mouse). Is. In particular,
When the movement is started from a predetermined range between the first display object and the second display object, both of these limit values are set while keeping the difference between the first limit value and the second limit value constant. Can be changed.

Further, when the parameter information itself is set instead of the limit value, if the present invention is applied, these parameters can be kept constant while keeping the difference between the first parameter information and the second parameter information constant. It is possible to easily change the setting of information.

[0017]

Embodiments of the present invention will be described below with reference to the drawings.

Further, a mouse cursor is displayed on the display screen of the display unit 7, and a click operation is performed by the mouse 6 (the mouse cursor is moved to the display object (object) on the display screen and the mouse button is pressed and immediately released). Or drag operation (position the mouse cursor on the displayed object on the display screen, move the mouse while pressing the mouse button, and release the mouse button at the target position).

The auxiliary operator 8 is an operator for setting parameter information. Various controllers such as a wheel and a slider can be used as the auxiliary operator 8, but here, a slider as shown by reference number 9 will be mainly described as an example. The musical tone generating section 10 generates a musical tone signal based on an instruction from the CPU 10.

In this electronic musical instrument, a voice selection screen can be displayed on the display 7 and the mouse 6 can be used to select a tone color (ie, voice) of a musical tone. After the voice is selected, a musical tone is sounded with the tone color of the selected voice. One voice is composed of a plurality of parameter information for defining one tone color. The user can change the setting of the parameter information forming the voice and change the tone color of the voice as desired. The setting change of the parameter information of such a voice is performed by the display 7
The voice edit screen is displayed on.

FIG. 2 is an example of a voice selection screen displayed on the display unit 7. The display screen on the upper side of the figure is a voice selection screen, and on the lower side of the voice selection screen, some operation mode selection buttons 21 to 23 for the user to select a function are displayed. These operation mode selection buttons 21 to
No. 23 is always displayed on the lower side of the screen regardless of what the upper display screen is, so that the user can always select a function.

The operation mode becomes the voice selection mode by setting the mouse cursor on the button 23 labeled "VOICE" and clicking the mouse button.
The voice selection mode is an operation mode in which one voice is selected from a plurality of voices. At this time, the voice selection screen shown in FIG.
The notation "OICE" is highlighted.

The voice selection screen displays a list of selectable voices. The user can select the desired voice by placing the mouse cursor on one of the voices and clicking the mouse button. In FIG. 2, the mouse cursor 24 is moved to "B-2
The state of clicking according to "COSMIC" is shown. Thereby, the voice "B-2 COSMIC" is selected. The notation of the selected voice "B-2 COSMIC" is reversed.

[VOICE EDI] at the bottom of the screen in FIG.
By setting the mouse cursor on the button 22 labeled "T" and clicking the mouse button, the operation mode becomes the voice edit mode. The voice edit mode is an operation mode in which the setting of each parameter information of the voice is changed (timbre data is edited). At this time, the voice edit screen (not shown) is displayed and the button 2 is pressed.
The notation “VOICE EDIT” in 2 is highlighted. On the voice edit screen, a parameter of a voice to be edited is designated, and the auxiliary operator 8 such as the slider 9 is operated to edit the parameter information (setting change).

In the electronic musical instrument of this embodiment, the auxiliary operator 8
The range of values that the parameter can take when editing the parameter information with can be specified in advance. Making such designation is called a controller set. The controller set is performed on the controller set screen.

"CONROLLER" at the bottom of the screen in FIG.
The button 21 labeled “SET” is a button for instructing to perform controller setting. By setting the mouse cursor on the button 21 and clicking the mouse button, the operation mode becomes the controller set mode, and the controller set screen is displayed. At this time, the notation of the button 21 is highlighted.

FIG. 3 shows an example of the controller set screen (upper screen in the figure). Buttons 21 to 23 are displayed on the lower side of the controller set screen.
Is highlighted. Reference numeral 31 is an area representing an auxiliary operator that is a target for setting a controller, and 32 is an area representing a function operated by the specified auxiliary operator, that is, a parameter specifying a range.

In FIG. 3, since "SLIDER" is displayed in the area 31, it can be seen that the auxiliary operator to be set by the controller is the slider 9. Further, since “VOLUME” is displayed in the area 32, when operating the volume with the slider 9, the parameter “V
It can be seen that the range in which "OLUME" is included is specified.

The user can specify the target of the controller set by directly inputting in the area 31. Also,
By directly inputting to the area 32, the parameter to be set by the controller can be designated. The input method may be input from a keyboard (not shown), or may be a method of clicking these areas with a mouse to display a list of selectable objects and parameters and specifying them.

In the controller set screen of FIG. 3,
The display 33 shows the slider 9 which is the target of the controller set.
It is a simulation of. Here, since the minimum position of the slider 9 is “0” and the maximum position is “127”, “0” indicating the minimum position is displayed below the slider display 33 and above the slider display 33. Indicates the maximum position "1
27 ”is displayed. The display 34 shows a knob (knob) portion of the slider 9. Since the current knob position is "100" in the possible range "0-127" of the position of the slider 9, "100" is displayed on the display 34.

The display 35 shows a slider having two knobs for designating a possible range of the parameter (here, "VOLUME") value which can be set by the slider 9.

The knob 36 labeled MAX is a knob for setting the parameter value (limit value MAX) when the slider 9 is located at the maximum position "127". In order to show the correspondence, the maximum position of the display 33 of the slider 9 and the knob 36 are connected by a dotted line. At present, the limit value MAX of the parameter corresponding to the maximum position of the slider 9 is "11.
Since it is set to "0", "110" is displayed next to the knob 36.
Is displayed.

The knob 37 labeled MIN is a knob for setting the value of the parameter (limit value MIN) when the slider 9 is located at the minimum position "0". In order to show the correspondence, the minimum position of the display 33 of the slider 9 and the knob 37 are connected by a dotted line. Since the limit value MIN of the parameter corresponding to the minimum position of the slider 9 is currently set to "30", "30" is displayed next to the knob 37.

Reference numeral 38 is a display showing a parameter value that can be calculated from the current position of the knob of the slider 9. In this example,
Since the range “0 to 127” of the position of the slider 9 corresponds (linearly corresponds) to the range “30 to 110” of the parameter value, 100 × (110−30) / 127 + 30 = 93 ( The value after the decimal point is the current parameter value.

Generally, when the range of the position of the slider 9 is "0 to 127", the current position of the slider 9 is SL, and the above-mentioned limit values of the parameter value are MAX and MIN, the calculated parameter value SLIDER is obtained. Becomes SLIDER = SL × (MAX-MIN) / 127 + MIN (Equation 1).

The user moves the mouse cursor 24 to the knob 36.
Alternatively, the values of MAX and MIN can be changed by dragging the knob 37 up and down in the figure. In particular, the magnitude relationship between MAX and MIN can be changed. For example, in FIG. 3, the mouse cursor 24 may be aligned with the knob 37 and dragged upward so that the knob 37 is positioned above the knob 36. Conversely, the knob 36 may be dragged downward so that the knob 37 is located above the knob 36.

FIG. 4 shows that when the knob 36 is on the lower side and the knob 37 is on the upper side, in other words, MAX <M, not MAX> MIN.
It is an example of the display 33 and the display 34 in the case of IN. The knob 36 is located below the knob 37, and MAX = 10. Further, the knob 37 is located above the knob 36, and MIN = 127.

In this case, the parameter calculation formula can be expressed by using the above symbols as follows: SLIDER = MAX-SL * (MIN-MAX) / 127 (Equation 2).

In FIG. 4, since the current position of the knob 34 of the slider 9 is "35", the current parameter value is "9".
5 "can be calculated. Therefore, the display 38 shows "95".
Is displayed. The reason why MAX and MIN are reversed in this way is that, in the case of the parameters of the electronic musical instrument, the direction of movement of the slider and the direction of change of the timbre may be sensuously matched in such a case.

The knob 36 representing MAX is represented by a rectangle, and the knob 37 representing MIN is represented by a triangle. This is so that the MAX knob 36 and the MIN knob 37 can be distinguished from each other.

In addition, the triangle 1 indicating the MIN knob 37
The three corners always face the MAX knob 36.
That is, when MAX is larger than MIN as shown in FIG. 3, one corner of the triangle of the knob 37 is upward, and when MAX is smaller than MIN as shown in FIG. 4, one corner of the triangle of the knob 37 is downward. I am trying.

In the electronic musical instrument of this embodiment, the settings of MAX and MIN can be changed by dragging the knob 36 and the knob 37 independently, and the interval between MAX and MIN, that is, the interval between the knob 36 and the knob 37 can be made constant. Can be translated.

FIG. 5 is a diagram for explaining the position where the mouse cursor is placed when starting the dragging of the knobs 36 and 37 using the mouse. 5A shows the case where the knob 36 is above the knob 37, and FIG. 5B shows the case where the knob 36 is below the knob 37.

In FIG. 5A, 51 is a knob 36, 3
7 is the center and is a rectangle showing a range of a width W and a length H in the up-down direction (the rectangle 51 and other auxiliary lines in FIG.
It is drawn for convenience of description and is not actually displayed on the display 7). H and W are fixed values. Now, assuming that the vertical interval between the knob 36 and the knob 37 is d (0 ≦ d ≦ 127), consider auxiliary lines 52 and 53 that divide the interval d into three equal parts.

When the mouse cursor is aligned with the shaded portion NBOTH between the auxiliary lines 52 and 53 and dragging is started, the knobs 36 and 37 are moved in parallel while keeping the interval d constant. When the mouse cursor is aligned with the range NMAX in the rectangle 51 above the auxiliary line 52 and dragging is started, only the knob 36 is moved. When the mouse cursor is aligned with the range NMIN within the rectangle 51 below the auxiliary line 53 and dragging is started, only the knob 37 is moved. In this way, depending on the position where the dragging is started, it is possible to distinguish between the movement of only the knob 36, the movement of only the knob 37, and the parallel movement of the knobs 36, 37, and the MAX, MIN
You can change the settings of.

Also in the case of FIG. 5 (b), the distance d between the position of the knob 36 and the position of the knob 37 is divided into three equal parts, and the auxiliary lines 54 and 55.
Considering the above, the same as in FIG. However, the knob 36,
Since 37 is reversed, the rectangle 51 above the auxiliary line 54
The area inside is NMIN, and the rectangle 5 below the auxiliary line 55
The range within 1 is NMAX.

Next, the operation of the electronic musical instrument of this embodiment (particularly the operation of the controller set) will be described with reference to the flow charts of FIGS.

FIG. 7 shows a main program executed when the power of the electronic musical instrument of this embodiment is turned on. First, initial setting is performed in step S71. Next, the operation event of the auxiliary operator 8 such as the slider 9 is detected in step S72, the operation event of the mouse 6 is detected in step S73, and the operation event of the performance operator 4 is detected in step S74.

In step S75, operation mode management is performed. In the operation mode management, the pressing of the operation mode selection buttons 21 to 23 displayed at the bottom of the screens of FIGS. 2 and 3 is detected, and when any one of the buttons is pressed, the operation mode indicated by the button is switched to. At the same time, a screen display according to the operation mode is performed.

In step S76, the current operation mode is determined. When the button 23 labeled "VOICE" is selected, it is the voice selection mode, and the process branches to step S77. "CONROLLER SET"
When the button 21 described as is selected, the controller is in the controller set mode, and the process branches to step S78. Button 22 labeled "VOICE EDIT"
When is selected, the voice edit mode is selected, and the process branches to step S79.

In step S77, the tone color (voice) selection processing as described with reference to FIG. 2 is performed. After that, in step S80, a sounding process is performed according to the operation of the performance operator 4, and other processes are performed in step S81, and then the process returns to step S72.

In step S78, controller setting processing is performed. This will be described later. Step S
At 79, tone color data editing processing (voice editing processing) is performed. After steps S78 and S79, the process branches to step S80.

FIG. 6 is a flowchart of the controller setting process in step S78 of FIG. First, in step S61, setting target operator specification processing is performed, and in step S62, function allocation setting processing is performed.

The setting target operator designating process is a process for designating a target to be set in the area 31 of the controller set screen shown in FIG. 3, that is, an auxiliary manipulator which is a target to set the controller. The function assignment setting process is a process of specifying a function to be set in the area 32 of the controller set screen of FIG. 3, that is, a function to be operated by the auxiliary operator (parameter to be specified in range).

Next, in step S63, a process of displaying the current value of the auxiliary operator is performed. As a result, the display 34 and the display 38 shown in FIG. 3 are executed. Next, in step S64, MIN and MAX setting processing is performed, and the process returns.

FIG. 8 is a flowchart of the MIN / MAX setting process. First, in step S91, it is determined whether the target auxiliary operator 8 is the slider 9. If it is not the slider 9, MIN and MAX setting processing for other auxiliary operators is performed in step S92, and the process returns. When the slider 9 is the target in step S91, it is determined in step S93 whether a drag operation of the mouse 6 has been detected.

When no drag operation is performed, M
Since there is no need to change the settings of IN and MAX, the process directly returns. When the drag operation is performed in step S93, the start position C where the drag operation is started (the position of the mouse cursor when the mouse button is pressed) is detected and stored in step S94. Next, in step S95, the drag amount D is detected. The drag amount D is detected as + in the direction of dragging upward in FIG. 5 and as − in the direction of dragging downward.

Next, in step S96, it is determined which area in FIG. 5 the detected drag start position C belongs to.
When the drag start position C is within the area NBOTH, MIN + D is calculated and set as a new MIN in step S97, and MAX + D is calculated and set as a new MAX in step S98. This allows MAX and M
This means that the amount of dragging D is moved in parallel while keeping the difference from IN constant. Then, it progresses to step S101.

If the drag start position C is within the area NMAX in FIG. 5 in step S96, only MAX is changed, so in step S99 MAX + D is calculated and set as a new MAX. Then, it progresses to step S101. When the drag start position C is within the area NMIN in FIG. 5 in step S96, the setting is changed only for MIN. Therefore, in step S100, MIN + D is calculated and a new MI is calculated.
Set as N. Then, it progresses to step S101.

In step S101, the magnitude relation between the set MAX and MIN is determined. In steps 102 and 104, the knobs 36 and 37 are displayed again.
Knobs 36 and 37 are at the positions after dragging (M
It is redisplayed at the position according to AX and MIN), but especially M
When AX ≧ MIN, the knob 37 indicating MIN is re-displayed as an upward triangle in step S102. vice versa,
When MAX ≧ MIN is not satisfied, MI is determined in step S104.
The knob 37 indicating N is re-displayed as a downward triangle.

After step S102, step S103
The above equation 1 is calculated with the parameter value SLIDER
To calculate. After step S104, step S105
The above equation 2 is calculated with the parameter value SLIDER
To calculate. After steps S103 and S105, in step S106, the parameter value SLIDER is output to the musical sound generating unit 10, and this parameter value SL is output according to the allocation function.
The setting of the actual tone parameter value is changed using IDER, and the process returns.

According to the present embodiment, it is easy to specify the case where it is desired to perform parallel movement while keeping the difference between MAX and MIN constant. Further, the knob 36 and the knob 37 have different shapes of the knobs to be displayed, and the knob 37 displays one corner of the triangle so as to always face the knob 36.
It is easy to see and operate even when 37 and 37 are reversed.

In the present embodiment, the interval between the knobs 36 and 37 is divided into three equal parts, and the intermediate region (NBOTH in FIG. 5).
Although it is recognized as an instruction for parallel movement when is dragged, the present invention is not limited to this, and may be moved in parallel when another predetermined area is dragged. However, since it is convenient in terms of operation to perform parallel movement when the knob and the vicinity of the middle of the knob are dragged, it is preferable to perform parallel movement in an intermediate region divided into three as in the present embodiment.

Further, in this embodiment, although the linear equations 1 and 2 are used to calculate the parameter value SLIDER from the current position SL of the slider, the limit values MAX and M are used.
Parameter value SLIDE as restricted to IN
Other calculation formulas may be applied as long as R can be calculated. Although the slider has been described as an example of the auxiliary operator, the auxiliary operator may not be the slider.

Further, in the present embodiment, the limit values MAX and MIN are set within the range 0 to 127 that the slider position can take, but the limit values are set from a wider range according to the parameters. Good. For example, for the slider position range 0 to 127, the parameters are -30 to
It is possible to set the range of 200 to MAX = 150 and MIN = -10.

Further, the method of setting the limit values MAX and MIN of this embodiment can be applied to the setting of the two parameters themselves. This allows the first parameter and the second parameter
It is possible to easily change the setting while keeping the difference with the parameter of.

[0070]

As described above, according to the present invention, MAX, which defines the range in which parameter information can be taken,
It is possible to easily change the settings of MAX and MIN while keeping the MIN difference constant. Further, when applied to the setting change of the two parameters, the setting can be easily changed while keeping the difference between the two parameters constant. In particular,
If the display objects displayed for setting MAX and MIN are different so that they can be distinguished from each other, MAX and M
Even when the IN is reversed, it can be easily distinguished and the operability is improved.
