BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an electronic musical instrument according to an embodiment of the present invention;
FIG. 1 is a block diagram showing a hardware configuration. A CPU (Central Processing Unit) 1 controls the operation of the parameter display device, and is connected to each unit via a bus 2.
A control program is stored in a ROM (Read Only Memory) 3, and the CPU 1 executes various controls based on the program. RAM (random
The access memory 4 has an area for storing timbre parameters, which will be described later, and an area that operates as a register, a flag, and the like. The tone data stored in the RAM 4 can be rewritten (edited), and the switch 7 and the mouse 10
Can be used to modify the data. The keyboard 5 has, for example, 61 keys, and its operation is detected by a keyboard detection circuit 6. The keyboard detection circuit 6 outputs a key code indicating a key operated on the keyboard 5, data indicating on / off of the key, and touch data (initial touch, after touch) indicating an operation intensity to the CPU 1 via the bus 2. I do. The switches 7 are various panel switches arranged on the panel surface of the apparatus, and the operation thereof is performed by a switch detection circuit 8.
And the detected switch operation information is output to the CPU 1 via the bus 2. The display circuit 9 is LC
D (liquid crystal display), etc., and displays various information such as timbre parameters. The mouse 10 designates an arbitrary position on the display circuit 9, clicks (turns the mouse on at a certain place and turns off at that place), and drags (turns the mouse on at a certain place and turns the mouse on as it is). The user can specify various functions on the display by performing an operation such as moving in a state and turning off a switch at a destination.

The tone generator circuit 11 employs, for example, an FM system, a waveform memory reading system, a physical model simulation system, and the like, and forms a tone signal based on tone color parameters stored in the RAM 4. In the present embodiment, one tone is composed of one or a plurality of elements, and it is possible to realize a complex tone in which a plurality of sounds overlap, a tone in which a plurality of parts can be played simultaneously, and the like. it can. The tone signal formed by the tone generator circuit 11 is supplied to the sound system 12 and is emitted as a tone.

FIG. 2 is a diagram showing a display example of the tone color parameter edit mode in the display circuit 9. Switch 7
When the upper edit switch (not shown) is operated, the switch detection circuit 8 detects this and switch operation information is supplied to the CPU 1 via the bus 2. And CPU1
Reads the timbre parameters from the RAM 4, displays them on the display circuit 9, and enters the timbre parameter edit mode. Hereinafter, every time the operation of the mouse 10 is detected by the CPU 1, the CPU 1 executes various processes based on the control program stored in the ROM 3. FIG. 2 shows a parameter display example of a two-element tone color. Reference numeral 9-1 denotes a tone color display area for displaying the tone number and tone name to be edited. In this example, "A-01" is displayed as the tone number, and "E.Piano (electric piano)" is displayed as the tone name. I have. A tone icon 9-2 is displayed in this area. The function of the tone icon 9-2 will be described later. 9-3
Is a menu button, and when this button is clicked with a mouse, a list of a plurality of timbres stored in the RAM 4 is displayed below the display screen. Then, by specifying an arbitrary tone from the tone color list with the mouse and dragging it to the tone icon 9-2, the tone to be edited can be changed. By specifying the timbre icon 9-2 with the mouse and dragging the timbre icon 9-2 to an arbitrary timbre area in the timbre list, the edited timbre parameters can be saved in the drag destination area. Reference numeral 9-4 denotes an effect button. By clicking this button with a mouse, the screen is switched to an edit screen for an effect relating to the tone being edited, but detailed description thereof is omitted.

Reference numerals 9-5, 9-6, 9-7, and 9-8 denote element buttons for selecting which of the four elements is valid. Each time the button is clicked with the mouse, the valid / invalid state is reversed. Here, elements 1 and 2 are effective, and the tone has a two-element configuration. When the button of the element 1 or 2 is clicked with the mouse in this state, the clicked element is invalidated, and the tone of one element configuration is obtained. Conversely, if the button of element 3 or 4 is clicked on with a mouse, the tone will have a three-element or four-element configuration. Reference numerals 9-9, 9-10, 9-11, and 9-12 denote element mute buttons, which mute the sound of a specific element when editing while listening to the sound of an element alone during editing. You can do it. In this example, since there is a two-element configuration of the elements 1 and 2, the mute for the elements 3 and 4 is unnecessary, so that the function of the mute buttons 9-11 and 9-12 is invalid. . This state is indicated by a broken line in the drawing. Reference numerals 9-13 and 9-14 denote up and down buttons. These buttons are effective only when editing a tone composed of three or more elements, and are ineffective here. This is indicated by a broken line in the drawing. 3 and 4 show a 4-element configuration for the up and down buttons.
Will be described later.

Reference numerals 9-15 and 9-19 denote display areas indicating element names. 9-15 includes "EP-1 (Electric Piano-1)" indicating the name of Element 1.
9-19, “FM-EP” representing the name of element 2
(FM electric piano) "is displayed. Below the element name display areas 9-15 and 9-19, parameter display areas 9-17 and 9-18, respectively.
And 9-21 and 9-22. The display areas 9-17 and 9-21 display a first parameter group relating to the volume, tuning, and other settings of each element, and the display areas 9-18 and 9-22 display the first parameter group relating to portamento and pitch bend of each element. Two parameter groups are displayed. The first parameter group is a parameter mainly relating to the balance of the entire timbre, and the second parameter group is mainly a parameter relating to the characteristics of the element itself. In addition, each element name display area 9-1
In 5 and 9-19, element icons indicated by 9-16 and 9-20 are displayed. By double-clicking these icons, the display area 9-1 is displayed.
7, 9-18, 9-21, and 9-22, it is possible to edit detailed timbre parameters of each element that cannot be represented, but the description is omitted here.

On this screen, it is possible to specify an arbitrary parameter with the mouse 10 and edit the value. For example, in the case of a parameter such as volume or detune that has a slider display other than the value display area, the value can be changed by designating the slider knob with a mouse and dragging it. Also, for those that do not have a slider display, such as microtuning and key assignment mode, when the value display area is specified with the mouse, a pop-up menu with multiple values appears, and one of the menus is displayed. Select a value. Alternatively, parameters designated by the mouse may be edited by various switches (numeric keys, ± keys, etc.) provided on the switch 7.

Next, a display example of a tone color parameter edit mode for a tone color of a four-element configuration will be described with reference to FIGS. The same parts as those in the display in FIG. In FIG. 3, the tone color name display area 9-1 shows "A-02" as the tone color number and "Brass" as the tone color name.
(Brass) "is displayed. Then, all of the element buttons 9-5, 9-6, 9-7, 9-8 are in a state of being selected as indicated by oblique lines. Then, the up button 9-13 is in a selected state, indicating that the first parameter group is displayed among the tone color parameters. That is, in the display of a tone parameter having a three or four element configuration, since there is not enough area to display all the parameters, the display is divided into a first parameter group display and a second parameter group display. An up switch 9-13 (corresponding to the first parameter group) and a down switch 9-14 (corresponding to the second parameter group) are selected.

Element name display areas 9-15, 9-1
9, 9-23, and 9-26 each include "Brass-
1 (Brass-1) "," Brass-2 (Brass-
2) "," Trumpet "," Sa
"W-Wave (sawtooth wave)" is displayed, and the element name indicating the characteristic of the sound of each element is displayed. Then, below the element name display area, the first parameter groups 9-17, 9-21, 9-24,
9-27 is displayed. The types of parameters displayed here are the same as the first parameter group in the two-element configuration parameter described above.

In FIG. 3, when the down button 9-14 is clicked on with a mouse, the display switches to that shown in FIG.
Here, it is shown that the down button 9-14 is in the selected state, and the second parameter group is displayed among the tone color parameters. Then, the second parameter groups 9-18, 9 of each element are displayed below the element name display areas 9-15, 9-19, 9-23, 9-26.
-22, 9-25 and 9-28 are displayed. The types of parameters displayed here are the same as those of the second parameter group in the two-element configuration described above.

As described above, in the parameter display of the four-element configuration, the displayed parameters are the first and second parameters.
, And the parameters for four elements are displayed between the groups. By clicking the up / down buttons 9-13 and 9-14, the first and second parameter groups are switched. In this four-element tone, when the number of elements is reduced by clicking the element buttons 9-5 and 9-6 with a mouse, and the two-element tone is displayed, the display format shown in FIG. Become. Conversely, in the two-element tone shown in FIG. 2, when the number of elements is increased by clicking the element buttons 9-7, 9-8 and the like with a mouse, and the four-element tone is displayed, the display shown in FIG. Format.

In the above embodiment, for a two-element tone color, both the first parameter group and the second parameter group are displayed on one screen for two elements, and for a four-element tone color, four elements are displayed. Since one of the first parameter group and the second parameter group is displayed on one screen for one element, an optimal display can be performed according to the number of elements. That is, when the number of elements is small, the number of parameters to be displayed is increased to increase the number of parameters that can be changed as much as possible, and when the number of elements is large, the number of parameters to be displayed at once is reduced to reduce the complexity of the display surface, The visibility is improved.

When the timbre has a three-element configuration, FIG.
Alternatively, one of the parameter display areas of the four elements in FIG. 4 may be displayed in a deleted form, or may be displayed in a display form dedicated to a three-element configuration. Also, in the case of a one-element configuration, similarly, one of the parameter display areas of the two elements in FIG. 2 may be displayed in a deleted form,
You may make it display in the display format only for 1 element structure.

The type and number of parameters to be displayed are not limited to those in the embodiment. For example, the present invention may be applied to parameters of effects (effects). When an effect in which a plurality of types of effects (for example, compressor, distortion, equalizer, chorus, reverb, etc.) are combined is displayed, the effect is displayed by the number of effects. The number of parameters for each effect may be changed. In the case where performance data of a plurality of tracks is displayed in an automatic performance, the number of display data may be changed according to the number of tracks (for example, only note data, note data and various control data). Both). Further, the display format is also arbitrary.

Further, the electronic musical instrument main body and the display device may be provided separately, and the parameter editing device may be provided separately from the electronic musical instrument.

[0020]

As described above, in the present invention, a designated element among a plurality of elements each consisting of a plurality of parameters is displayed on the display means, and the display means displays the designated element in accordance with the number of elements to be displayed. Since the number of parameters for each element to be displayed is changed, a display that is always easy to see can be displayed according to the number of elements, and the editing workability is improved.
