Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a performance parameter input device for inputting performance parameters or performance parameter values prior to or during the generation of a musical tone.

[0002]

2. Description of the Related Art Conventionally, in electronic musical instruments, automatic performance devices, etc.,
Operators such as an up / down key, a data entry slider, and a rotary encoder are widely used to set performance parameters. Further, in order to control the tone of the tone being sounded, an operator such as a pitch bender or a wheel independent of the keyboard is widely used.

[0003]

However, in the past, when setting parameters, the display unit and the manipulator are separated, so that the user intuitively operates the manipulator while looking at the display of the display unit. Had a problem. Also, regarding musical sound control, it is necessary to operate an operator such as a pitch bender or a wheel, which is independent of the keyboard, together with the keyboard.
It took a lot of effort to master the operation.

In Japanese Patent Laid-Open No. 6-202656, a cordless electronic pen and a magnetic electronic pen sensor integrated on the lower surface of a display are used, and the resonance phenomenon between the electronic pen and the electronic pen sensor is used to obtain the same. A technique for setting parameters based on position data of an electronic pen has been proposed. For example, it is described that after pressing the electronic pen against the display and pulling it upward / downward, the electronic pen is held as it is, so that numerical data is continuously incremented / decremented at a predetermined speed to set parameters. According to this method, the parameter setting operation is easy.

However, this technique uses an electronic pen or the like, which complicates the circuit configuration and causes a cost increase. In addition, if the numerical data is continuously incremented / decremented only at the initial speed, it is difficult to set the amount of change in the numerical data that suits both cases when the numerical data is small or large. As a result, there is a lack of proper operability in parameter setting.

In view of the above circumstances, it is an object of the present invention to provide a performance parameter input device capable of inputting a performance parameter or a parameter value of a performance parameter with a simple operation.

[0007]

A first performance parameter input device of the present invention which achieves the above object, is a touch panel for detecting a contact position and a display content arranged on the back side of the touch panel for visual recognition through the touch panel. A performance parameter input device having a display panel whose display contents can be freely changed, and for inputting performance parameters or parameter values of performance parameters according to the display contents of the display panel and the operation state of the touch panel In the above, it is characterized in that it is provided with a fast-forwarding means for changing the display content of the display panel at a changing speed according to the sliding distance of the sliding operation for moving the contact position while keeping contact with the touch panel.

In the above-described first performance parameter input device of the present invention, since the fast-forward speed changes according to the sliding distance, the parameter to be changed or the change width of the parameter value or the operator's change operation preference. Even if they are different, fast-forwarding can be performed at an appropriate speed, and desired parameters or parameter values can be easily input.

Here, in the first performance parameter input device of the present invention, when the fast-forwarding means performs a sliding operation from inside a predetermined area on the touch panel beyond a boundary of the predetermined area. It is preferable that the display content of the display panel is changed at a changing speed according to the sliding distance starting from the boundary of the predetermined area. When touching and sliding on the display area of the parameter or the parameter value, there is a problem in that the display content is hidden by the pen or finger or the like in contact therewith and is difficult to see. Therefore, if the parameter or the parameter value is changed when sliding outside the display area, the parameter or the parameter value can be changed while checking the display without disturbing the display.

The second performance parameter input device of the present invention is a touch panel for detecting a contact position and a display which is arranged on the back side of the touch panel so that the display content can be visually recognized through the touch panel and the display content can be freely changed. In a performance parameter input device having a panel and for inputting a performance parameter or a parameter value of a performance parameter according to the display content of the display panel and the operation state of the touch panel, inside a predetermined area on the touch panel. After the contact is detected, when the sliding operation is performed to move the contact position while touching the touch panel beyond the predetermined area, the parameter change to change the parameter or parameter value corresponding to the predetermined area. It is characterized by having means.

In the above-described first performance parameter input device of the present invention, it has been explained that it is preferable to perform the fast-forward operation when sliding out of the display area for the fast-forward operation, but this is limited to the fast-forward operation. Instead, it generally holds when changing a parameter or a parameter value like the second performance parameter input device of the present invention.

A third performance parameter input device of the present invention is a touch panel for detecting a contact position and a display which is arranged on the back side of the touch panel and is visible through the touch panel. In the performance parameter input device, which has a panel and which inputs a performance parameter or a parameter value of a performance parameter according to the display content of the display panel and the operation state of the touch panel, intersects each other on the touch panel. The parameter or the parameter value is changed in accordance with the sliding distance of the sliding operation for moving the contact position in the first direction out of the two directions while the touch panel is being touched, and the first of the two directions is selected. The parameter or parameter value changed according to the sliding operation in the second direction different from the direction It is constant, or characterized by comprising a parameter changing means for changing the predetermined default value.

Here, in the third performance parameter input device of the present invention, the parameter changing means does not perform a sliding operation in the second direction after a sliding operation in the first direction. It is preferable that when the non-contact state is entered, the parameter or parameter value changed by the sliding operation in the first direction is returned to the parameter or parameter value before the sliding operation.

There is a case where it is desired to temporarily change the parameter or the parameter value and confirm the effect. In such a case, when configured as the third performance parameter input device of the present invention, the value is tentatively changed by a sliding operation, the changed value is confirmed, or the default value is restored or the original value before the change is made. The value can be returned to, and the operability is improved.
Even in the third performance parameter input device described above,
When the parameter changing means performs a sliding operation from the inside of the predetermined area on the touch panel in the first direction over the boundary of the predetermined area, the sliding distance from the boundary of the predetermined area as a starting point. It is preferable to change the parameter or the parameter value according to the above.

This is because, as described above, both the confirmation of the display contents and the operation for changing the display contents are achieved. A fourth performance parameter input device of the present invention includes a touch panel that detects a contact position and a display panel that is arranged on the back side of the touch panel and that can be visually recognized through the touch panel. In a performance parameter input device for inputting a performance parameter or a parameter value of a performance parameter in accordance with the display content of the display panel and the operation state of the touch panel, the performance parameter input device has two of two directions on the touch panel that intersect with each other. According to the sliding distance of the sliding operation for moving the contact position while touching the touch panel in the first direction, the parameter to be changed or the set of parameter values is selected, and Within the selected set according to the sliding distance of the sliding operation in the second direction different from the first direction Characterized by comprising a parameter changing means for changing the parameters or parameter values.

Here, the set of parameters means a set of a plurality of parameters as a set of a set, and the set of parameter values means a set of values of a plurality of parameters that can be set for a given parameter. When there are multiple sets of parameters or parameter values that are alternatively selected, it is usually necessary to separately perform the operation of selecting the set and the operation of changing the parameter or parameter value in the set selected by the set. There is.

According to the fourth performance parameter input device of the present invention, the operation of selecting a set and the operation of changing the parameter or parameter value in the selected set are performed in a unified manner, and the operability is improved. For example, it is possible to easily set the tone parameter for each part of the multitimbral tone generator. Here, in the above-mentioned fourth performance parameter input device of the present invention, the parameter changing means is arranged to move from the inside of a predetermined area on the touch panel to the second
When a sliding operation is performed in the direction of, beyond the boundary of the specified area, the parameter or parameter value within the selected set is set according to the sliding distance starting from the boundary of the specified area. It is preferably changed.

This is because, as described above, both the confirmation of the display content and the operation for changing the display content are achieved. Further, a fifth performance parameter input device of the present invention includes a touch panel that detects a contact position and a display panel that is arranged on the back side of the touch panel and that the display content can be visually recognized through the touch panel. In a performance parameter input device for inputting a performance parameter or a parameter value of a performance parameter in accordance with the display content of the display panel and the operation state of the touch panel, the performance parameter input device has two of two directions on the touch panel that intersect with each other. Of the first direction of the two directions while changing the parameter or the parameter value according to the sliding distance of the sliding operation of moving the contact position while touching the touch panel in the first direction. Is a parameter or parameter per unit sliding distance depending on the sliding distance of the sliding operation in the different second direction. The amount of change of the parameter value is different from the amount of change of the parameter or the parameter value per unit sliding distance in the sliding operation in the first direction, and the parameter changing means for changing the parameter or the parameter value is provided. It is characterized by

According to the fifth performance parameter input device of the present invention, since the'sensitivity 'of changing a parameter or parameter value differs depending on the sliding direction, a parameter or parameter value having a wide setting range is set. sometimes,
It is possible to easily and accurately set within a limited area on the touch panel. Here, in the fifth performance parameter input device of the present invention, when the parameter changing means performs a sliding operation from inside a predetermined area on the touch panel beyond a boundary of the predetermined area, the predetermined value is set. Unit sliding according to the sliding distance from the boundary of the area and whether the sliding operation is the sliding operation in the first direction or the second direction It is preferable that the parameter or the parameter value is changed with the change amount per distance.

Thus, the easiness of confirming the display contents and the operability are harmonized. The sixth performance parameter input device of the present invention includes a touch panel that detects a contact position, and a display panel that is arranged on the back side of the touch panel and whose display content is visually recognized through the touch panel, the display content being freely changeable. In the performance parameter input device for inputting the performance parameter or the parameter value of the performance parameter according to the display content of the display panel and the operation state of the touch panel, in detecting the contact position on the touch panel, A touch position detecting means for detecting the touch position by using a different detection method depending on which of the plurality of touch screen positions the touch panel surface is divided into And

In the operation of the touch panel, when a region mainly operated by a finger or the like and a region mainly operated by a pen are mixed, a finger having a wider contact area takes a longer time to determine a contact position. At this time, if the fingers are pushed in uniformly for the operation of the finger, the contact position determination in the area operated by the pen will be unnecessarily slow and the high-speed response will be lacking. If it is adjusted for the operation of, there is a possibility that the contact position may be erroneously determined when operated with a finger.

According to the sixth performance parameter input device of the present invention, since the detection method is divided according to the area, the most effective contact position detection is performed on the entire touch panel, and the detection accuracy and the high-speed response are achieved. Compatibility is achieved. further,
A seventh performance parameter input device of the present invention has a touch panel that detects a contact position, and a display panel that is arranged on the back side of the touch panel and whose display content can be visually recognized through the touch panel and whose display content can be freely changed. , In a performance parameter input device for inputting a performance parameter or a parameter value of a performance parameter according to the display content of the display panel and the operation state of the touch panel, a plurality of pitch designation regions are displayed on the display panel Display means,
In response to contact with any one of the areas on the touch panel corresponding to each of the plurality of pitch-specified areas displayed on the display panel, the musical tone of the pitch corresponding to the contacted area is generated. A tone control means for changing the parameter value of at least one of the parameters defining the tone being sounded in response to a sliding operation of moving the contact position while touching the touch panel after the touch. It is characterized by that.

The seventh performance parameter input device is
The present invention relates to musical tone generation control and musical tone control during sound generation. Usually, pronunciation control (for example, keyboard) and tone control during pronunciation (pender, ribbon controller, wheel, etc.)
Are configured to be operated by different operators, and in such a configuration, it takes time to learn the operation technique. On the other hand, according to the seventh performance parameter input device of the present invention, a pitch designating area of a design such as a keyboard is displayed on the display panel and corresponds to the pitch designating area of the touch panel. It is possible to control the musical sound being generated by touching the area and controlling the sound generation and then performing the sliding operation as it is, thereby realizing a more intuitive and simple operation.

The seventh performance parameter input device is not limited to a mode in which the parameter value of one parameter (for example, pitch) is changed by one sliding operation.
A mode in which the parameter values of a plurality of parameters (for example, pitch and panning) are simultaneously changed is also included. Further, in the seventh performance parameter input device of the present invention, the musical tone control means are different from each other among the parameters that define the musical tone being generated according to the direction of the sliding operation after the contact. The parameter value of the parameter may be changed.

As described above, by changing the parameter values of a plurality of parameters by one sliding operation or changing the parameter values of different parameters according to the sliding direction, a rich and novel feature that has never existed before can be obtained. Performance expression is possible.
In the seventh performance parameter input device,
It is preferable that the musical tone control means changes the parameter value when the sliding operation is performed beyond the boundary of the contacted area.

The above-mentioned pitch designation area has a certain size so that it can be easily contacted within the area. Therefore, the contact point changes for each contact operation. In such a situation, if the musical tone control is started for the first time when it is slid out of the area, the starting point of the musical tone control is objectively determined regardless of the initial contact position,
Intuitive and error-free operation is possible, improving operability.

Further, in the seventh performance parameter input device, the display means displays a plurality of pitch designation areas on the display panel and also information corresponding to a contact or sliding operation. Preferably there is. As a result, the effect of the musical sound control can be confirmed visually as well as the sound. Further, in the seventh performance parameter input device, there is provided parameter selection means for selecting a parameter whose parameter value is changed by the tone control means in accordance with a sliding operation of moving the contact position while being in contact with the touch panel. It is preferable.

By doing so, the control effect can be selected according to the preference of the operator, and musical tone control which is not possible with conventional musical instruments can be performed. In addition, this parameter selection means,
By selecting multiple parameters that are controlled according to the sliding motion and freely selecting the parameters that are controlled for each sliding direction, for example, in the case of a pitch change, the keyboard player can move in the horizontal direction. (That is, bender lever or glissando),
The guitarist can select an operation direction most suitable for the operator, such as selecting a vertical direction (for example, choking), which greatly improves operability.

FIG. 3 is a diagram for explaining the position detection principle of the touch panel shown in FIG. 2, and FIG. 4 is a touch panel and C
It is a circuit diagram of an interface unit interposed between PU. In FIG. 3, x in the position information of the touch panel 12
An explanatory view (a) for detecting the position in the direction and an explanatory view (b) for detecting the position in the y direction are shown.

First, regarding the principle of detecting the position in the x direction,
This will be described with reference to FIGS. The touch panel 12 shown in FIG. 3A has two sheets 1 on which resistors are uniformly applied and which are vertically stacked with a predetermined distance from each other.
It is composed of 2x and 12y.

The sheet 12x includes the sheet 12x,
Terminals 12x _{1 on} the left and right sides of FIG. 3 (a) facing each other,
12x ₂ and the seat 12y is provided with the top and bottom 2 of the seat 12y facing each other in FIG. 3 (a).
Terminals 12y ₁ and 12y ₂ are provided on the sides. on the other hand,
An "H" level signal is output from both the ports 1 and 2 of the CPU 14 shown in FIG. 4, whereby both the tristate buffer 36a and the transistor 36b that form the interface section 36 become conductive, and the terminal 12x ₁ is grounded. A voltage V is applied to the terminal 12x ₂ . On the other hand, C
An “L” level signal is output from both the ports 3 and 4 of the PU 14, and as a result, both the tristate buffer 34c and the transistor 34d are turned off. Here, the point x on the touch panel 12 shown in FIG.
When pressed with, the sheets 12x and 12y come into contact,
A voltage drop occurs according to the position in the x direction of the x point of the sheet 12x pressed by the touch pen 31, and the dropped voltage is output from the terminal 12y ₂ . The voltage output from the terminal 12y ₂ is input to the A / D 1 of the CPU 14 via the circuit including the resistor 32 and the capacitor 33, and is A / D converted. In this way, the position in the x direction is detected.

In order to detect the position in the y direction,
Both of the ports 3 and 4 of the CPU 14 shown in FIG. 4 output a signal of'H 'level, whereby both the tristate buffer 36c and the transistor 36d become conductive,
The terminal 12y ₁ is grounded and the voltage V is applied to the terminal 12y ₂ . Also, "L" from both ports 1 and 2 of CPU14
A level signal is output, which turns off both the tristate buffer 34a and the transistor 34b. Here, x of the touch panel 12 shown in FIG.
When the point is pushed by the touch pen 31, a voltage drop occurs according to the position of the x point pushed by the touch pen 31 in the y direction on the sheet 12y, and the dropped voltage is output to the terminal 12x ₂ . This voltage in the y direction is
4. The signal is input to the A / D 2 via the circuit of the capacitor 35 and is A / D converted. In this way, the position in the y direction is detected.

The above-mentioned x-direction and y-direction by the CPU 14
Direction is alternately detected to detect the pressed position on the touch panel.

The position in the y direction is detected with.

Next, when detecting the position in the x direction, switching operation is performed by switching x and y in the above switching operation, setting 33 as the capacitor and 32 as the resistance, and performing these switching operations alternately. The pressing position on the touch panel is detected by. In the unpressed state, the capacitor 33 or 35 on the detecting side is always discharged, so that the voltage of the ground level is detected. The CPU also detects, by comparing the detected voltage with the voltage at or near the ground level, whether or not the voltage is pressed, and whether or not the pressed position is the operation area on the touch panel. These scans are C
It is processed every time a periodical interrupt of a timer (not shown) of the PU 14 occurs.

In this way, the voltage output from the touch panel 12 is A / D converted and digitalized by the CPU 1
By loading and processing in "4, touch panel 1
2 is pressed (changed) "," touch panel 12 is pressed (state) "," pressed position on touch panel 12 in the pressed or pressed state ",
"Change of pressed position in pressed state (sliding operation)",
"The touch panel 12 is released from the pressure (change)",
It is possible to obtain information such as “the touch panel 12 is not pressed (state)”.

The process for obtaining these pieces of information can be easily determined by sequentially storing the pressing and pressing position information and the like within the fixed time on the RAM 15. However, when the touch panel 12 is pressed from a non-pressed state, a voltage representing the correct pressed position is not immediately output, so that it is necessary to allow a slight time lag in general. In addition, this time lag increases as the pressure is increased with a large pressing area (for example, a finger), and it takes time to determine the position with respect to the pressing. Therefore, it is desirable to change the position determination method for the pressing operation in an area operated mainly with a small pressing area such as a touch pen and an area operated mainly with a large pressing area such as a finger.

By the way, from the touch panel 12 to the CPU 1
In order to determine the actual pressed position (coordinates) on the touch panel 12 from the digital value read in 4, it is necessary to first calibrate the digital value and the actual position. FIG. 5 is an explanatory diagram of calibration on the touch panel. The calibration operation can be performed using, for example, a pair of diagonal points in the detection area of the touch panel 12 as shown in FIG. In FIG. 5, first, point A is pressed with a touch pen or the like to obtain voltage data (XA, YA) at point A. Next, B
Similarly for point, press the voltage data at point B (X
B, YB). Here, A on the touch panel 12
If the distance in the x direction determined by the point and the point B is LX and the distance in the y direction is LY, the displayable area of the display unit 11 is determined by the distance LX in the x direction and the distance LY in the y direction. Since the area does not change in practical use, if the voltage data when an arbitrary point C in this area on the touch panel 12 is pressed is (XC, YC), the point B of the touch panel 12 is used as the reference point. The absolute position (LXc, LYc) of the pressed point is LXc = (LX / (XA-XB)) * (XC-XB) LYc = (LY / (YA-YB)) * (YC-YB).

However, here, it is assumed that the point B generates a lower voltage value when pressed than the point A, and that the resistance value change depending on the position on the touch panel 12 has sufficient linearity. To do. As described above, in the operation panel 20 of the present embodiment, by aligning the positions of the display 11 and the touch panel 12 with each other, the pressing operation and the sliding operation on the touch panel 12 can be performed by the display elements on the display 11. Can be associated with location.

FIG. 6 is a view showing a display example on the operation panel shown in FIG. A “keyboard” icon 61 simulating a keyboard shown in FIG. 6 represents the keyboard of the selected part, and by touching this keyboard, the tone range of the keyboard and the tone of the selected part are displayed. It is possible to play, and it is possible to perform various musical tone controls for the musical tone being produced by sliding.

The "<" and ">" icons 62 are for shifting the sound range of the keyboard indicated by the "key" icon 61 in units of octaves. "OCT" icon 63
Indicates the range of the keyboard indicated by the "key" icon 61,
It plays the role of returning to the standard range regardless of the current pronunciation range.
The “V.PARA” icon 64 is an icon for switching to a musical tone parameter setting screen controlled by the vertical sliding movement of the keyboard of the selected part.

The "H. PARA" icon 65 is an icon for switching to a musical tone parameter setting screen controlled by the lateral sliding movement of the keyboard of the selected part. The "INST" icon 66 is an icon for switching to a screen for assigning a tone color to be pronounced to the keyboard of the selected part.

The "+" and "-" icons 67 blink when the display elements that can be changed are touched with the touch pen. When the display is blinking, these "+" and "-" icons 67 are displayed.
This is an icon for changing the value by touching the "-" icon 67. It should be noted that the values do not change even if these "+" and "-" icons 67 are pressed when the display elements are not blinking so that the values are not changed carelessly.

The message display area 68 is 16 characters x 1
It has a display area of a line size, and when it is touched, for example, a timbre name is displayed. Where "keyboard"
Icon 61, "<"">" icon 62, "OCT"
The icon 63 and the message display area 68 are areas mainly operated by the touch pen. Meanwhile, “V.PAR
"A" icon 64, "H.PARA" icon 65,
"INST" icon 66, "+""-" icon 67
Is an area mainly operated by a finger. The areas operated by these fingers are compared with the areas operated by the touch pen, and it takes time to determine the operation position.

That is, in the area operated by the touch pen, the scanning is performed twice, and the touched position is determined by the value of the second time. In the area operated by the finger, the scanning is performed three times and the third time is performed. The position touched is determined by the value of. In this case, the method of determining the number of scans is to detect the approximate position on the touch panel with the value obtained by the first scan, and use that value for the second scan corresponding to the area operated by the touch pen. If it corresponds to the area operated by the finger, the position is determined by the third value.

The number of times of scanning is not predetermined as described above, but the values output by scanning are sequentially stored in a buffer, and when the values converge within a certain range, the position is determined by that value. May be determined. Further, the number of scans is not determined by the value of the first scan, but a touch panel divided in advance according to the number of scans is used. One of the divided touch panels determines the position by the second scan, and the other touch panel. Then, the determination may be detected by the third scanning.

As described above, in the case where the area mainly operated by the finger and the area mainly operated by the pen are mixed on the touch panel, the area to be judged is determined in the judgment of the pressed position on the touch panel. By adopting different position determination methods depending on the situation, for example, the position determination is delayed even to the point where the touch pen should be operated by uniformly adjusting it for finger operation, and conversely, it is uniformly adjusted for touch pen operation. Therefore, it is possible to prevent the possibility that the position of the area where the finger should be operated is erroneously determined. Therefore, by dividing the determination method according to the area, the most efficient determination can be performed for the entire touch panel, and a comfortable operation system can be realized.

In the present embodiment, by touching the "keyboard" icon 61 on the operation panel 20, the built-in multitimbral sound source of 16 parts is sounded, and the sliding operation in the vicinity of the "keyboard" icon 61 will be described later. , It is possible to control the tone parameter being sounded. In addition to the control of the musical tone being sounded, it is possible to assign a tone color to each part of the multitimbral and to set musical tone parameters to be controlled at the time of sounding with the “keyboard” icon 61. These will also be described later.

FIG. 7 is a diagram (display example) for explaining the operation of assigning a tone color (instrument) to each part on the operation panel. When the “INST” icon 66 on the operation panel 20 is touched, a message display area 68 is displayed.
7A, "part08 = A.Piano" shown in FIG.

When the touch pen is slid below the display area 68a as shown in FIG. 7, the timbres are switched at regular time intervals in the order of the arrows written below "A.Piano2" in FIG. As long as you continue touching even if you stop sliding operation, the parameter that sets the tone color is switched at regular intervals, (hereinafter, the state in which the parameters are switched at regular intervals is called "fast forward".
That. ) The time interval of fast-forwarding or the amount of change (for example, whether to increase or decrease by 2 or by 3 in the order of the tone colors stored in the table) changes according to the sliding distance.

For example, it is impossible to change the setting of values in 256 steps with a certain amount of change for every certain sliding distance. However, as described above, the parameters or parameters are changed depending on the sliding operation distance. By changing the change speed (fast-forward speed) of the set value, that is, the fast-forward state is always maintained as long as the button is pressed, and the feed speed (or the degree of change =, for example, one increment or three increments) ) Is changed according to the sliding distance, it is possible to easily set various range values even in a limited area.

The setting (value) is changed by this operation when the display area 68a is slid beyond the upper end or the lower end of the range surrounded by the broken line shown in FIG. 7B. It is conceivable to change the setting when sliding operation is performed for a certain distance from the initial pressing position.
There is a problem in that the display may be difficult to see. Therefore, when the sliding operation stays within a predetermined range on the touch panel, a dead zone is provided so that the parameter or the set value of the parameter is not changed. Since the setting is changed when sliding out of), the display is easy to see and you can operate it comfortably.

In the message display area 68, "par" is displayed.
t08 = A. When "Piano2" is displayed, "A. The display area 68a of "Piano2" is touched with the touch pen 31 to display "A. By blinking the character string "Piano2" and sliding to the left or right while touching it, you can switch to the part according to the sliding distance. The tone color name assigned to is displayed, for example, when sliding for a certain distance in the direction of the left arrow (←) in FIG. 7B, “part08 =” is displayed as shown in FIG.
A. Piano2 ”to“ part07 = A.P. Bas
Similarly, when sliding in the direction of the right arrow (→), “part08 = A. Piano2 ”to“ part09 = T.P. Sax ".

The setting (value) is changed by this operation when the display area 68a is slid beyond the left end or the right end. Here, the concept of a set necessary for the following description will be explained. A set is a set of parameters having a certain correlation, and here corresponds to a part.

In this way, musical tone parameters (here, parameters for setting the tone color) according to the vertical sliding distance.
If you slide the knob to the right for a certain distance, you can set the same parameters (parameters that set the tone) of the next set (Part09), and if you slide the switch up and down again, you can set the same parameter (Part09). ) Same parameter value (here, T.Sax) can be changed.

Also, by pushing and sliding to the left for a certain distance, it becomes possible to set the same parameters (parameters for setting the timbre) of the previous set (here, Part 07), and further slide up and down with pushing. Then, the parameter value of the set (Part07) (here, A.Bas
s) can be changed. In conventional electronic musical instruments, if the same parameter can be set in multiple sets, it is necessary to perform the set change operation and the parameter setting operation separately, but this makes it possible to perform the set change operation and the parameter change operation. It is comfortable because it can be done uniformly. For example, it is easy to set musical tone parameters for each part of a multitimbral tone generator.

In this embodiment, as will be described in detail later, the "keyboard" icon 61 is slid vertically and horizontally with a touch pen to change preset musical tone parameters and control the musical tone being sounded. You can do it. FIG. 8 is an explanatory diagram (display example) of an operation of setting in advance a musical tone parameter that changes when the keyboard is slid in the vertical direction during musical tone generation.

When the "V.PARA" icon 64 on the operation panel 20 is touched with the touch pen 31 or a finger, a message display area 68 is displayed as shown in FIG.
"V.Para1 = CUTOF" is displayed on
This brings up a musical tone parameter setting screen controlled by a vertical sliding operation on the "keyboard" icon 61.
Next, when the touch pen 31 touches the display area portion 68a in which "CUTOF" is displayed in the message display area 68, the character string display of "CUTOF" blinks. Here, when the display portion 68a is slid upward with the touch pen 31 still being touched, as shown in FIG.
It changes to "ODUL" and "BEND". On the other hand, when it is slid downward while being touched, it changes to “RESON” and “AFTER” as shown in FIG. 8B.

The tone parameters that can be set are as follows. (The description of the contents controlled by each tone parameter is omitted.) BEND: Pitch bend MODEL: Modulation CUTOF: Cutoff frequency RESON: Resonance AFTER: Aftertouch VOL: Volume EXP: Expression PAN: Pan WAH: Wah effect VIB: Vibrato. Late LFO: LFO late REV: Reverb send CHO: Chorus send DEL: Delay send OFF: No setting If the musical tone parameter is set to “OFF”, the “keyboard” icon 61 will be vertically oriented while the musical tone is being sounded, as described later. Even if the slide operation is performed, the tone parameter is not controlled.

FIG. 8 (c) is a switching display diagram when the camera is slid to the left and right while being touched. That is, when sliding right while pressing, the V.
Para2, V.I. If you slide to the left in the state of pressing in the order of Para3, it is not shown by the arrow in the drawing,
For each predetermined sliding distance, V. Para3, V.I. It is possible to switch to the parameter to be set in the order of Para2. In this way, the setting of the musical tone parameter that changes when the “keyboard” icon 61 is slid in the vertical direction is “V.Para1”.
~ V. Specify with Para3 ".

Here, the "keyboard" during the musical sound generation described later
By sliding the icon 61 in the vertical direction, "V.
a1 ”to“ V. Up to three musical tone parameters set to Para3 "can be controlled simultaneously.
The sliding operation and the method of changing the setting (fast forward, etc.) are the same as those in the case of assigning the tone color to the above-mentioned part.

FIG. 9 is an explanatory diagram (display example) of an operation for setting in advance a musical tone parameter that changes when the musical instrument is sounded by sliding horizontally on the "keyboard" icon. When the “H.PARA” icon 65 on the operation panel 20 is touched by the touch pen 31 or a finger, “H.Mode” is displayed in the message display area 68 as shown in FIG.
= PORTA ”is displayed, and the tone parameter setting screen controlled by the lateral sliding operation of the“ keyboard ”icon 61 is displayed.

Here, in the message display area 68, "PO
When the display area 68a in which "RTA" is displayed is touched with the touch pen 31, the character string display of "PORTA" blinks. When the touch pen 31 is slid up and down while being touched, FIG. As shown, "GLI
It changes to "S" or "OFF". On the other hand, the display area section 6 in which "PORTA" of the message display area 68 is displayed
If you touch 8a with the touch pen 31, "PORTA"
The character string display of flashes. Here, when the touch pen 31 is slid to the right in the state of being touched, as shown in FIG. 9C, “H. Mode” to “H. Para” are sequentially performed.
1 ", H.Para2", and not shown "" H. P
You can switch to ara3 ".

Further, when the touch pen is slid to the left in the state of being touched, the H.V. P
ara3, H.A. Para2, H.P. It can be switched in the order of Para1. "H.Par1", "H.Pa
ra2 ”,“ H. The musical tone parameter set to "Para3" is the "V. Para1 ”,“ V. Para
2 "," V. It is the same as the musical tone parameter set to “Para3”. Para1 ”to“ H. Up to three musical tone parameters set to Para3 ″ can be controlled simultaneously.

In the control in the horizontal direction, unlike the control in the vertical direction described above, there is a mode setting of "H.Mode". When "H.Mode" is set to other than "OFF", "H.Para1" to "H.Para3"
Is treated as “OFF”. Here, "HM
The tone parameters set in "ode" (see FIG. 9B) will be described.

In the "GLIS", by pressing an arbitrary keyboard area with a touch pen, a musical tone corresponding to the keyboard area is generated, and the keyboard area in which sound is being generated is slid laterally to enter another keyboard area. The glissando performance is enabled by instructing the tone signal corresponding to the keyboard area to be produced for each time. "H.Para1" to "HP
All ara3 "are treated as" OFF ".

In "PORTA", by pressing an arbitrary keyboard area with a touch pen, a musical tone corresponding to the keyboard area is generated, and the keyboard area in which sound is being produced is slid in a lateral direction to enter another keyboard area. Each time, the pitch of the musical tone signal is controlled by the sliding action so that the pitch before entering another keyboard area smoothly changes to the pitch corresponding to the keyboard area after entering another keyboard area. Enables portamento performance. "H.Para1" to "HP
All ara3 "are treated as" OFF ".

"OFF" means that even if a different key area is entered by a sliding operation in the horizontal direction while one key is sounding, the "GLI"
As in the case of “S” or “PORTA”, musical tone control pronunciation instruction and pitch control corresponding to the keyboard area are not performed, and “H.Pa
ra1 ”to“ H. Each setting of Para3 ”becomes effective,
In the lateral sliding operation, the musical tone is controlled with respect to the sound being generated.

Returning to FIG. 9A again, the description will be continued. When the display area of "PORTA" is touched with the touch pen 31 in the state shown in FIG. 9A, "PORT" is displayed.
"A" blinks. If you slide to the right as it is, "H. Par
a * ”(* indicates any one of 1 to 3) is displayed. Here,“ H. Para1 = CUTOF ”is displayed. Next, when the touch pen touches the display area of“ CUTOF ”,“ CUTOF ”blinks. If you slide upward while touching, you will see "MODU
"L", "BEND" ... On the other hand, if you slide downward while touching,
"N", "AFTER" ... Here, "O
When set to "FF", the tone parameter control is not performed even if the keyboard is slid laterally during tone generation.

In the present embodiment, the tone parameters that can be set by "H.Para *" are "V.Pa."
Although it is the same as “ra *”, it is not always necessary for the setting candidates in the vertical and horizontal directions to be the same for parameters for which it is desirable to give directionality to control. The parts may be different from each other.
FIG. 7 is an explanatory diagram of sound generation and musical sound control by the “keyboard” icon.

However, in this example, V. PARA1 = “BEND” V.P. PARA2 = “PAN” V.P. PARA3 = "OFF" H.P. MODE = “GLIS” H.M. PARA1 = “OFF” PARA2 = “OFF” It is assumed that PARA3 is set to "OFF".

When the display area of the key "E" of the keyboard icon 61 shown in FIG. 10A is touched by the touch pen 31, the musical tone of the tone color of the currently selected part is "<".
The pitch is E at the octave range set by the ">" icon 62. While sounding, the "●" shown in Fig. 10 (b) and Fig. 10 (c) is displayed in the display area of the keyboard "E".
Lights up.

At the time of sounding, the sounding message may be transmitted to an external device using MIDI or the like. When touching and sliding upwards, the pitch increases (V.PARA1 = “BEND”) and stereo localization occurs in accordance with the vertical sliding distance from the position 1 shown in FIG. Shifts to the right, and (V.PARA2 = “PA
N ") When the slide operation is performed downward, the pitch is lowered from the position 2 shown in FIG. 10B as a starting point and the stereo localization is shifted to the left. At this time, the changed parameter and its value are displayed in the message display area 68 (FIG. 11).
(See below).

When the user touches and slides in the lateral direction, the retrigger operation is performed for each key area at the positions 3 and 4 shown in FIG. 10C to perform glissando.
H. In the example shown here, PARA is all "OFF" (invalid), but when valid, musical tone control is performed according to the sliding distance in the lateral direction according to the setting of "H.PARA *".

As described above, by performing the sliding operation while pressing the display area of the key "E" which is the pitch finger area, the value of the musical tone parameter for controlling the musical tone generation instruction and the musical tone being generated is set. Can be changed. Generally, it takes time to learn the operation technique with the configuration of keyboard + vendor, keyboard + ribbon controller, keyboard + wheel, but by controlling musical sounds on the keyboard in this way, more intuitive and easy operation is possible. Becomes

The tone control by the sliding operation in the vertical and horizontal directions can be controlled according to the sliding distance from the pressing point, but since the pressing point is slightly different each time, the control effect is in that case. There is no choice but to confirm by sound. Therefore, since intuitive control becomes difficult, in the present embodiment, the effect comes to be exhibited when it is slid out of the key area where the pressing is started. In this way, when the sliding operation stays within the predetermined range on the touch panel, by providing a dead zone that does not change the tone parameter, this dead zone area serves as a kind of "guide" for operation. Since the position where the control effect starts to appear is fixed,
It can be operated intuitively regardless of the variation in the pressing start position.

FIG. 11 is an explanatory diagram of sound generation and tone control by the “keyboard” icon, which is different from FIG. In the message display area 68 shown in FIG. 11, changes in the musical tone parameters due to the upward sliding operation after the touch pen touches the area of the key “E” are roughly displayed. Here, V. Para1, V.I. The control states of the pitch bend (BEND) and the pan (PAN) set in Para2 are indicated by display symbols 111, 112 and V.P. * Indicating "OFF" set in Para3 is displayed.

In FIG. 11, an upward triangle mark (▲) means that the parameter is controlled in the increasing direction, and a downward triangle mark (▼) means that the parameter is controlled in the decreasing direction, although not shown. To do. Furthermore, H. Para1, H.P. P
ara2, H.A. Three “OF” set in Para3
* That indicates "F" is also displayed.

In this way, by displaying the change of the musical tone parameter by the sliding operation, the effect can be confirmed not only by the sound but also by the visual observation. In the present embodiment, the message display area 68 is displayed in a schematic form due to the size of the display area 68. However, when there is a space in the display area, the present invention is not limited to this, and the parameter value itself and the effect of musical tone control are displayed graphically. May be expressed as

In general, it is practically sufficient in some cases that it is not necessary to control each of the musical tone parameters independently, but to control them together by correlating them. Therefore, it is not only possible to control two types of musical tone parameters vertically and horizontally two-dimensionally combined, such as one type of musical tone parameter for a vertical sliding operation and one type of musical tone parameter for a horizontal sliding operation. Plural kinds of musical tone parameters may be simultaneously controlled by the sliding operation in each direction. The present embodiment is configured so that such control can be realized, and many tone parameters can be freely mixed by vertical and horizontal sliding motions.
Therefore, it is possible to perform rich and novel musical performances that are not possible with conventional electronic musical instruments.

As described above, in this embodiment, since a plurality of tone parameters controlled by the vertical and horizontal sliding motions can be selected, the control effect can be freely selected and combined according to the operator's preference. Then, it becomes possible to perform musical tone control that is not possible with conventional musical instruments. Also, since the directionality of the operation can be freely selected, for example, in the case of pitch change, the keyboard operation selects the horizontal direction (that is, the bender lever or glissando), and the guitarist selects the vertical direction (for example, choking). The most suitable operation direction for the operator can be selected.

Although a sound source is built in this embodiment, an external sound source may be connected via MIDI.
In that case, M such as pitch bend and modulation
If the IDI message is defined, the sound source may be controlled by using them, or the sound source may be controlled by using a system exclusive message or the like that can recognize the sound source. Also, by connecting to a sound source via an interface other than the MIDI standard such as RS-422, MID
The sound source may be controlled by a protocol other than I.

Further, in the structure of this embodiment, an automatic performance device may be built-in or externally connected to record / reproduce musical tone control information by a sliding operation. The tone control parameters controlled by the sliding operation may be parameters other than those mentioned in this embodiment. Further, in the display device according to the present embodiment, the “keyboard” icon has one octave and one note, but it may have more keys. The display is
Any of liquid crystal, CRT, fluorescent display tube, LED, etc. may be used.

Further, although the analog type touch panel is used in the present embodiment, a matrix type (digital type) transparent touch panel having a sufficiently large resolution may be used. In this case, assuming that the switches are arranged at all of the detectable positions, the position may be detected by the same process as that of the normal mechanical switch. Next, a second embodiment of the present invention will be described.

FIG. 12 is a view showing an operation panel provided in an automatic performance device incorporating the second embodiment of the performance parameter input device of the present invention. This automatic performance device can perform an automatic performance, and its basic configuration is similar to that of the block diagram shown in FIG. In addition, regarding the position detection technology of the touch panel that constitutes the operation panel,
This is the same as the embodiment.

The operation panel 120 shown in FIG. 12 is composed of a display 121 and a transparent touch panel 122 arranged on the display 121. First, the screen displayed on the operation panel 120 will be described. "TEM
The current performance tempo is displayed in "PO" 123. In FIG. 12, 120 is displayed as the tempo value.

In "PATTERN" 124, the currently selected pattern is displayed. Here, ROCK
_24 / ORG is displayed. "DRUM SE
In “T” 125, the drum set name assigned to the currently selected pattern is displayed. Here, "R
“OMM” is displayed. Reset icon 126
Is for returning to the beginning of the selected pattern by pressing when the performance is stopped.

The stop icon 127 is used to stop the pattern performance by pressing it during the performance. The play icon 128 is for starting the performance of the selected pattern when pressed while the performance is stopped. In this embodiment, a preset rhythm pattern can be selected and automatically played. rhythm·
The pattern consists of 6 patterns, one set, intro (INT), ending (END), original (O
RG), variation (VAR), fill-in 1 (F
L1) and fill-in 2 (FL2). These divisions are called "divisions".

By pressing the play icon 128 and the stop icon 127, the selected pattern can be repeatedly played. Here, in order to change the performance tempo of the pattern, the tempo value display area in FIG. 12 is touched with a touch pen and then a sliding operation is performed. Further, in order to change the type / division of the pattern, the display area 124a of the pattern name in FIG. 12 is touched with the touch pen and then the sliding operation is performed.

For each pattern (including division),
Rhythm instruments used for rhythm performance can be assigned in set units, and this set is called a "drum set".
This drum set is optimally assigned in advance for each pattern (preset set), but the assignment can be temporarily changed and played.

To change the drum set assignment, the display area 125a of the drum set name in FIG. 12 is touched with a touch pen and then the sliding operation is performed. FIG. 13 is an explanatory diagram of a tempo change operation on the operation panel shown in FIG. As shown in FIG. 13, when the tempo value display area 123a is slid up and down with a touch pen, the value can be changed by 10 for each constant sliding distance, and when sliding in the left and right direction, each value can be changed for each constant sliding distance. The value can be changed by one.

Therefore, it is possible to slide up and down when making a large change and slide left and right when making a fine adjustment, so that the tempo can be easily adjusted by a simple operation. In this way, if the parameters are roughly adjusted according to the vertical sliding distance and finely adjusted according to the left and right sliding distances, there is no need to perform a fast-forward operation when setting parameters with a wide setting range. Even in a limited area, setting can be performed easily and accurately.

This operation method is not limited to this example, and can be applied to all parameters requiring rough adjustment and fine adjustment. FIG. 14 is an explanatory diagram of a rhythm pattern changing operation on the operation panel shown in FIG. As shown in FIG. 14, when the display area 124a for the pattern name is slid up and down with the touch pen, the pattern type can be changed, and when it is slid horizontally, the division can be changed.

Therefore, if you want to select different rhythm styles, you can slide up and down, and if you want to keep the rhythm style fixed and select by role in the song, slide left and right. You can easily select the desired pattern. This operation method is also not limited to this example, and can be applied to the setting of all parameters having a conceptually strongly independent element and a conceptually strongly related selection element.

For example, the music genre of the pattern may be selected in the vertical direction, and the pattern variation in the music genre selected in the horizontal direction may be selected. FIG. 15 is an explanatory diagram of the assignment changing operation of the drum set used in the rhythm pattern on the operation panel shown in FIG.

As shown in FIG. 15, a drum set can be provisionally selected by sliding the drum set name display area 125a in the vertical direction. This is for selecting a desired set during performance of a pattern or the like. This is because they will not play on another drum set on the way. Then, after the temporary selection, sliding to the right determines the drum set to be changed, and the set is actually switched.

If the user makes a mistake and makes a temporary selection, the touch pen can be released from the touch panel in the temporarily selected state to restore the previous set. To return to the preset (default value), make a temporary selection and then slide to the left to preset (default value).
Can be returned to. If you want to return to the preset set (default value) after performing a certain number of confirmation operations and performing, if you make a temporary selection and slide to the left,
Assignments can be returned to the preset set.

Therefore, according to this method, the rhythm set settings can be changed without carelessly changing the playing state, and the initial settings can be returned to the initial settings after the change with a uniform and simple operation. it can. This operation method is also not limited to this example, and can be applied to all parameters that require a final operation.
