Abstract

PURPOSE:To facilitate setting and altering a parameter by designating one of operators displayed on a display means by a two-dimensional operator and varying a parameter corresponding to an operator designated by a one- dimensional operator. CONSTITUTION:Display contents, plural operator groups, stored in a screen memory means 4 are displayed on the display means 2. Through the operation of the two-dimensional operator 10, the designated display element displayed on the displays screen of the display means 2 is moved and positioned on either of the operators. Data corresponding to the operator position, that is, the position of the designated display element, is supplied to a parameter altering means 12 from the two-dimensional operator 10, and the parameter altering means selects the parameter corresponding to the data. When a user operates the one-dimensional operator 14, the value of the selected parameter varies with its manipulated variable. Simultaneously, a display altering means 6 alters the operator display designated by the two-dimensional operator 10 according to the manipulated variable of the one-dimensional operator 14. Thus, parameter setting and altering are facilitated.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a data display input device that uses a display section to change parameters and data.

(Prior art) Conventionally, a plurality of controls such as buttons and sliders for changing parameters or data are displayed on a display section, and operations on the screen are performed using two-dimensional controls such as a mouse and a trackball. Parameters and data were changed by specifying one of the children and then using the numeric keypad or by performing a pseudo operation on the two-dimensional operator as if operating the actual operator. According to this, controls such as volume controllers and sliders, which normally require multiple layers, are completely unnecessary, the number of parts and manufacturing processes are significantly reduced, resulting in cost reduction, and there are no mechanical contacts or moving parts. Therefore, long-term reliability is also improved.

Such a method is very effective when used in electronic musical instruments such as synthesizers, which have a large number of operators for setting and changing many parameters.

Furthermore, so that the amount of operation of the displayed operator can be recognized, the display of the designated operator on the display screen is changed according to the variable amount of the parameter or data, as if the actual operator had been operated. configured to change. This gives the user a feeling as if they were operating an actual controller.

(Problem to be solved by the invention) However, due to their structure, two-dimensional controls such as mice and trackballs are not suitable for subtle operations such as changing parameter values by operating normal parameter controls. This made it difficult to operate. Additionally, using a two-dimensional controller whose shape is completely different from the actual parameter controller may feel very strange to users who have used conventional controllers to set parameter values, and it may take some time to get used to it. could not be operated accurately and quickly.

(Object of the invention) The present invention has been made in view of the above-mentioned conventional problems,
The purpose is to provide a data display input device that allows easier parameter setting change operations.

(Structure and operation of the invention) FIG. 1 is a block diagram showing the configuration of the present invention.

In the figure, the display means 2 includes a screen memory means 4 storing data for displaying a plurality of controls, and a display variable means 6.
connected via. Further, an instruction display means 8 for displaying an instruction display element for instructing display contents is connected to the display means 2, and a two-dimensional operator 10 for moving and displaying the instruction display element is connected to the instruction display means 8. It is connected. Further, the two-dimensional operator 10 is connected to a parameter variable means 12 in which a plurality of types of parameters are stored and whose values can be varied, and a one-dimensional operator 14 for varying parameter values is also connected to this parameter variable means 12. Ru. Further, the two-dimensional operator 10 and the one-dimensional operator 14 are connected to a display variable means 6 that changes the display contents from the screen memory means 4.

The operation of this circuit will be explained below.

First, the display means 2 displays display contents stored in the screen memory means 4, that is, a plurality of groups of operators.

Here, the two-dimensional operator 10 is operated to move the instruction display element displayed on the display screen of the display means 2 and position it on one of the operators. Data corresponding to this operator position, that is, the position of the instruction display element, is supplied from the two-dimensional operator 10 to the parameter variable means 12. The parameter variable means 12 selects a corresponding parameter based on this data. Here, when the user operates the one-dimensional operator 14, the value of the selected parameter is varied according to the amount of operation. At the same time, the display variable means 6 changes the two-dimensional operator 1
The operator display specified by 0 is varied according to the amount of operation of the one-dimensional operator 14.

As described above, according to the present invention, one of the operators displayed on the display screen can be specified using the two-dimensional operator 10, and the value of the parameter corresponding to that operator can be varied using the one-dimensional operator 14. Can be done.

(Example) FIG. 2 is an external view of an electronic musical instrument using the data display input device according to the present invention. In the figure, a display unit 30 such as a CRT is provided at the top of the main body of the electronic musical instrument, and on the left side thereof,
A dial 32 for changing parameter settings is provided. A trackball 36 as a two-dimensional operator is provided on the right side of the keyboard 34, and a switch 38 is arranged above the ball 36. Furthermore, a group of operators 40 for operating the musical instrument is also provided on the left side of the musical instrument body. Therefore, while looking at the display section 30, the performer operates the trackball 36 with his right hand to select the necessary operator displayed.
The user operates the dial 32 with his left hand to change the settings of parameter values.

FIG. 3 shows a circuit diagram of the electronic musical instrument in FIG. 2. In the figure, the memory 42 includes various parameters and the display 30.
Data such as the operator group and/or parameter name displayed on the screen are stored. The dial 32, trackball 36, and operator group 40 are A/D converters 44, 46, 4, respectively.
The digital data is converted into digital data and input to the CPU 50 via the CPU 50. The CPU 50 displays the display unit 3 based on these data and the signal from the switch 38.
0, a group of operators or parameter names and an instruction display element are displayed, and the values of the parameters in the memory 42 are changed. Further, the CPU 50 creates data for musical tones to be generated based on the parameters in the memory 42 and key code data from the keyboard 34, and performs processing to supply the data to the sound source 52.

The sound source 52 creates a musical tone signal based on this data, and causes the soundon stem 54 and the speaker 56 to generate the musical tone.

The detailed operation will be explained below using the display form diagrams of the display unit 30 shown in FIGS. 4 to 8 and the flowcharts shown in FIGS. 9 to 13.

FIG. 4 shows the display form of the display unit 30 in a normal state. At the top of the display section 30, there is an icon display 30a, which indicates the parameters to be selected.
It shows that it is divided into I, EFFECT, and 0PTION usages, and in this embodiment, the parameter names required for each usage are read out and displayed. At the bottom thereof, a group of operators 3, Ob, for operating parameters are displayed. In the figure, the right side shows operators for controlling the mixer, and eight tracks are displayed. A portion of the mixer master is displayed on the right side. Figure 5 shows one track of this mixer, and the top four knobs 3
0c is used to set equalizer panning, effects, etc., and slider 30d is used to control volume.

Furthermore, a cursor 30e as an instruction display element that is moved by operation of the trackball 36 is also displayed on the display unit 30.

Next, the operation of changing parameter values will be explained using the flowchart of FIG.

First, in step A-1, it is determined whether the trackball 36 has been operated, and if YES, the trackball 36 is operated.
The cursor 30e is moved on the screen of the display unit 30 in response to the movement operation (step A-2). Then, the address data of the display position of this cursor 30e on the screen is sent to the CPU.
50 (step A-3).
), proceed to the next step A-4. Also, step A-1
Even if no moving operation of the trackball 36 is detected in step A-2 to A-3, the process proceeds to step A-4. Then, in step A-4, dial 32
It is detected whether or not it has been turned, and if no, the process returns to step A-1. If YES, it is determined whether the contents of the IAo register mentioned above are 0 (step A-5). In this embodiment, the IAo register being O means that the cursor 30e is not on the operator group 30b in the display section 30, and if YES in this step, the process returns to step A-1. And if No, cursor 3
0e means that it is on one of the operators in the operator group 30b, and the contents of the IAo register are set as address data PADD specifying the area in the memory 42 where the parameter data PD is stored (step A- 6). Then, the parameter data PD stored in the memory 42 is read out using this address data PADD, and the CPU 5
0 changes the value of the parameter data PD according to the amount of change in operation of the dial 36. At the same time, cursor 30e
Change the display state of the control located at the position. For example, if the cursor 30e is moved to the position of the slider 30d and the dial 32 is rotated, the tone m of the generated musical tone will be varied, and the displayed operation knob of the slider 30e will be moved up and down.

Furthermore, the operation of assigning necessary parameters to desired displayed controls will be explained.

The flowchart in FIG. 10 is a schematic flowchart showing the operation. As shown in the figure, the operation is divided into a normal state step B, a window display state step C, and an assignment specification state step D.

FIG. 11 is a detailed flowchart of this normal state step B. In this state, the display state is as shown in FIG. First, in step B-1, it is detected whether the trackball 36 has been moved. And YES
Then, the cursor 30e is moved and displayed in response to the movement operation of the trackball 36 (step B-2), and the address data indicating the position of the cursor 30e is stored in the CPU 50.
The A register is read (step B-3) and the process proceeds to step B-4. If NO in step B-1, the process proceeds to step B-4 without performing steps B-2 and B-3. Then, in step B-4, it is determined whether the value of the IA+ register is O, and if it is 0, the process returns to step B-1. Here, the content of the IAI register being 0 means that the cursor 30e is not on the icon 30a on the display section 30. Then place the cursor 30 on the icon 30a.
If e exists, the process proceeds to step B-5, and it is determined whether the switch 38 is turned on. If it is not turned on, the process returns to step B-1. If it is turned on, the process advances to window display state step C.

FIG. 12 shows a detailed flowchart of window display state C.

A screen will appear. Specifically, as shown in Figure 6, rEQ HI GHJrEQ is superimposed on the normal state display.
MIDJ rEQ LOWJ rEFC5EN
The parameter name of DIJ rEFEC5END2J rPANJ is displayed on the window screen.

Of course, the normal state display may be deleted and only this window screen displayed. In the next step C-2, it is determined whether the trackball 36 has been moved again,
If YES, the cursor 30e is moved on the screen in response to the movement of the trackball 36 (step C-2), and the address data corresponding to the position of the cursor 30e is sent to the CPU.
Read to the IA2 register in 50 (Step C-4
).

If the trackball 36 does not move, step C-3;
The process proceeds to step C-5 without performing the process in C-4. In this step C-6, it is determined whether the content of the IA2 register is O. If the content of the IA2 register is O, it means that the cursor 30e is not located on the parameter name display in the window screen, and in this case, step C-
Return to 2.

If it is not 0, place cursor 30 on any parameter 8
Since there is e, the process advances to the next step C-6. Here, it is determined whether the switch 38 has been turned on, and if it has not been turned on, the process returns to step C-2. If it is turned on, the process proceeds to step C-7, where the parameter name corresponding to the IA2 register is displayed as the cursor 30e, and the window display is erased. Figure 7 shows rEQ as a parameter.
LOW” is selected, and the cursor 30e indicates the parameter name from the arrow shape.
It becomes J. Thereafter, the process moves to step D, which is an assignment specification state.

FIG. 13 shows a detailed flowchart of the assignment specification state step D. First, in step D-1, it is detected whether or not the trackball 36 has been operated to move.
If S, the cursor 3 corresponds to the movement of the trackball 36.
Move 0e (Stella 7'D-2). FIG. 8 shows a state in which the cursor 30e has been moved to 30f, which is one of the operating knobs. Then, address data indicating the position of the cursor 30e is read into the rA3 register in the CPU 50 (step D-3). If the trackball 36 has not been moved, steps D-2 and D-3 are not performed. Then, in the next step D-4,
Determine whether the content of the IA3 register is 0, and if it is O,
Since this means that the cursor 30e is not on the operator display, the process returns to step D-1, and if it is not O, it is determined that the cursor 30e is located at any position on the operator display, and the process advances to step D-6. In this step switch 38
It is determined whether or not the is turned on, and if it is not turned on, the process returns to step D-1, and if it is turned on, the process returns to step D-6.
Then, the position address of the cursor 30e is changed so that the value of the displayed parameter can be changed at the operator position currently under the cursor 30e.

In this way, it becomes possible to assign a desired parameter to any one of the displayed control groups.

In this embodiment, after selecting a parameter, the cursor 30e changes its shape to represent the parameter name.
It may be in another shape or may remain in the shape of an arrow. Further, although the trackball 36 is used as the two-dimensional operator in this embodiment, it may be a mouse, and the dial 32 is used as the parameter operator, but it may be in the form of a slider. Furthermore, in this embodiment, one operator is designated one by one, but it is also possible to provide a plurality of parameter operators and change the settings of the same number of parameter operators at once.

(Effects of the Invention) As described above, according to the present invention, one of the operators displayed on the display means can be specified using the two-dimensional operator, and the specified operator can be selected using the one-dimensional operator. Since you can change the value of the corresponding parameter, you can switch between two-dimensional controls and use normal controls, such as volume, volume, etc.
Since there is no need to perform pseudo operations such as operating sliders, operations can be performed very quickly and accurately. In particular, since the one-dimensional operator can perform operations similar to those of conventional operators, even a user who is not accustomed to the operation can reliably perform fine adjustments of parameters, etc., which required skill with the two-dimensional operator.
