Abstract

PURPOSE:To set and alter a parameter or data needed by one display screen by allocating a parameter required by a user to either of operator gourds displayed on a display means. CONSTITUTION:With contents in a second screen memory 8 displayed on the display means 2, a first storage means 16 stores data corresponding to one parameter when its name is designated by a two-dimensional operator 14. When contents in a first screen memory 4 are displayed on the display means 2 after a second storage means 18 stores the data in the first storage means 16, the data corresponding to one operator designated by the two-dimensional operator 14 is stored. A parameter altering means 20 alters data input to a parameter altering means 22 from the two-dimensional operator 14 so that the parameter altering means 22 selects a parameter stored in the first storage means 16 when the two-dimensional operator 14 designates the operator stored in the second storage means 18. Consequently, a parameter or data needed by one display screen can be set and altered.

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 volume controls and sliders for changing parameters or data are displayed on a display section, and two-dimensional controls such as a mouse and a trackball are used to control which of the controls on the screen is displayed. 1, then use the numeric keypad to
Alternatively, parameters and data have been changed by performing a pseudo operation on a two-dimensional operator as if it were an 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 that 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.

(Problems to be Solved by the Invention) However, there is a limit to the size of the display section due to the size of the device itself, and there is a limit to the number of operators that can be displayed on the display section. If there are operators that set too many parameters or data, it becomes impossible to display all of the operations at once. Of course, there is also a method of dividing the control group into several groups and switching the display for each group, but when setting parameters or data, when using actual controls like this, it is unnecessary to perform operations. This is extremely troublesome, and even if there are a large number of parameters or data, it is actually rare to change all of them at once, and often only certain parameters or data are changed. In such cases, it is a burden on the user to switch the display screen one by one to find the desired operator display.

(Object of the Invention) The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to provide a data display input device that uses a display section to change settings of parameters or data. The objective is to enable the user to change the settings of parameters or data as necessary.

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

In the figure, a first screen memory means 4 in which data for displaying a plurality of operators is stored is connected to the display means 2 via a display variable means 6. Additionally, a second screen memory means 8 storing data for displaying a plurality of parameter names and an instruction display means 10 for displaying an instruction display element on the display means 2 are also connected. Of these, the second screen memory means 8 is connected with a changeover switch means 12 for displaying the contents on the display means 2, and the instruction display means 10 is connected to the second screen memory means 8 to display the display contents by moving this instruction display element on the screen. A designated two-dimensional operator 14 is connected. Further, the two-dimensional operator 14 is connected to a first storage means 16 and a second storage means 18. This first storage means 16
When the parameter name stored in the second screen memory means 8 is stored in the display means 2 by the changeover switch means 12, the data corresponding to the parameter name specified by the two-dimensional operator 14 is stored. , second storage means 18
Thereafter, when the contents of the first screen memory means 4 are stored in the display means 2, data corresponding to the operator display designated by the two-dimensional operator 14 is stored. Both storage means 16-18 are connected to parameter selection and change means 20. A two-dimensional operator 14 is connected to this parameter selection changing means 20, and the means 20 is a circuit that converts data from this two-dimensional operator 14 and supplies it to the connected parameter changing means 22. . The parameter variable means 22 is a circuit that stores a plurality of types of parameters, selects a parameter corresponding to the data from the parameter selection and change means 20, and changes the parameter using the parameter operator 24.

This parameter is input to the connected equipment.

Further, the parameter operator 24 and the two-dimensional operator 14 are
It is connected to a display variable means 6 for varying the display of the operators in the screen memory means 4.

The operation of this configuration will be explained below.

First, normally, the display means 2 displays a group of operators in the first screen memory means 4. Here, the changeover switch means 12
is operated to display the parameter name of the second screen memory means 8 on the display means 2, and then the two-dimensional operator 14 is operated to move the instruction display element to a predetermined parameter name and specify it. Data corresponding to the parameter name is stored in the means 16. After this, the first screen memory means 4
When the two-dimensional operator 14 moves one instruction display element to a predetermined operator display and designates it, the data corresponding to that operator is stored in the second storage means 18. After this, when any two-dimensional operator 14 of the displayed operator group is operated to specify, the specified data is transferred to the parameter variable means 2 via the parameter selection and change means 20.
Enter 2. Based on this specified data, the parameter variable means 22 selects a corresponding parameter from among the various stored parameters, and its value is varied by operating the parameter operator 24. In response to the operation n of the parameter operator, the display changing means 6 changes the operator display specified by the two-dimensional operator 14 as if it had been operated. When the two-dimensional operator 14 specifies the operator stored in the second storage means 18, the parameter selection change means 20 causes the two-dimensional operator 14 to select the parameter corresponding to the first storage means 16. Change the specified data from. For this reason, the parameter variable means 22
selects the corresponding parameter in the first storage means 16.

In this way, the types of parameters to be variably changed can be freely set for each operator displayed on the display means 2.

(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,

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 trunk ball 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 the 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, the display section 3
Data such as the operator group and parameter names displayed at 0 are stored. The dial 32, the trunk ball 36, and the 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 i' based on these data and the trigger signal from the switch 38.
The controller group or parameter name and the instruction display element are displayed at l<30, and the value of the parameter in the memory 42 is 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 for supplying the data to the sound source 52. The sound source 52 creates a musical tone signal based on this data, and sends it to the sound system 54 and seven speakers 56.
to generate musical sounds.

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 section 30 in a normal state. There is an icon display 30a at the top of the display section 30, and the parameter to be selected is EDITlMIXERlMULTI.
, EFFECT, and OP'rION. In this embodiment, the necessary parameter names are read out and displayed for each purpose. At the bottom thereof, a group of operators 30b for operating parameters is 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 four knobs 30c at the top
The slider 30d is used to set the equalizer, effects, etc., and the slider 30d is used to control the 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 in the IAO renostar (step A-3
), proceed to the next step A-4. Also, if no movement operation of the trunk ball 36 is detected in step A-1, the process proceeds to step A-4 without performing steps A-2 to A-3. 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 above-mentioned IAO register are 0 (step A-5). In this embodiment, the IAO register being 0 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 30
e means that it is on one of the operator groups 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 reads out the parameter data PD stored in the memory 42.
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 volume of the generated musical tone is varied and the displayed operation knob of the slider 30e is 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, it is detected whether the trackball 36 has been moved in step B-1. And YE
If S, the cursor 30e is moved and displayed in response to the movement operation of the trackball 36 (step B-2), and address data indicating the position of the cursor 30e is read by the IAI register in the CPU 50 (step B-3).
Proceed to step B-4. If No in step B-1, the process proceeds to step B-4 after performing steps B-2 and B-3. Then, in step B-4, IAI
Determine whether the value of the register is 0, and if it is 0, go to step B
Return to -1. Here, the content of the IA register being O means that the cursor 30e is not on the icon 30a on the display section 30. When the cursor 30e is located on the icon 30a, 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.

In this embodiment, it is assumed that the MIXER menu is selected. First, in step C-1, IAI
A window screen corresponding to the register will appear. Specifically, as shown in Figure 6, r is superimposed on the normal state display.
EQ HIGHJ rEQ MIDJ rEQ
LOWJ rEFEC5ENDIJ rEFEC
5END2J The rPANJ parameter name 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, and if YES, the cursor 30e is moved on the screen in response to the movement of the trackball 36 (step C-2), and the position of the cursor 30e is The address data corresponding to is read into the IA2 register in the CPU 50 (step C-4). Tiger 5. If there is no movement of the ball 36, the process advances to step C-5 in which steps C-3 and C-4 are performed. In this step C-5, IA2
Determine whether the contents of the register are O. If the content of the IA2 register is 0, it means that the cursor 30e is not positioned on the parameter name display in the window screen, and in this case, the process returns to step C-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 A2 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 (Schip 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 IA3 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, I
It is determined whether the contents of the A3 register are 0 or not. If 0, it means that the cursor 30e is not on the control display, and the process returns to step D-1. If it is not O, the cursor 30e is moved to any position on the control display. It is determined that there is, and the process proceeds to step D-5. In this step, it is determined whether the switch 38 has been turned on, and if it has not been turned on, the process returns to step D-1, and if it has been turned on, the process proceeds to step D-6, where it is displayed at the operator position currently under the cursor 30e. The position address of the cursor 30e is changed so that the parameter value can be changed.

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, the parameters required by the user are assigned to any of the operator groups displayed on the display means, so that there are many parameters. Users can also freely select only the parameters they need and assign them to any position on the screen, and can switch display screens or search for the control display they need, just like before. This eliminates the need for this, greatly improving operability.
