In the electronic musical instrument 10 having the above-described configuration, a characteristic point is control related to switching of a screen to be displayed on the display 18. Therefore, this point will be described below.
First, FIG. 2 shows the mutual relationship among a plurality of screens displayed by the electronic musical instrument 10.
The electronic musical instrument 10 can display various screens on the display 18 as screens for displaying the contents of the settings made in the electronic musical instrument 10 and accepting a change operation of the setting contents. The relationship between the screens is as shown in FIG.

  That is, first, for each of several operation modes, screen sets S, T, and U that are sets of screens used in the operation mode are prepared. The operation mode is, for example, a voice mode in which one timbre is assigned to each one or a plurality of note ranges and a sound is generated with the timbre in accordance with a performance operation, and a performance that defines a plurality of timbres in one or a plurality of note ranges is assigned There are a performance mode in which a plurality of sounds are pronounced according to a performance operation, a song mode in which a song is played back using a sequencer function, and the like. FIG. 2 shows an example in which there are three screen sets, but the number is not limited to this.

Each of the screen sets S to U includes a top screen that is displayed first when a corresponding operation mode is selected, a lower screen that is displayed when a predetermined operation is performed while the top screen is displayed, It is composed of a plurality of screens such as a next lower screen that is displayed when a predetermined operation is performed while the screen is displayed. These screens can be expressed in a tree structure based on the transition order of the screens as shown in FIG. Here, the lower screen represents all screens other than the top screen, that is, all screens in lower layers other than the highest layer in the tree structure of the screen set. In FIG. 2, the arrow indicates the transition direction of the screen, but it is also possible to return to the previous screen.
Further, as shown in FIG. 2, in each of the screen sets S to U, a plurality of screens having different display formats are prepared for the top screen.

These screens and transitions between the screens will be described with reference to FIGS.
FIG. 3 is a diagram illustrating an example of a plurality of display formats of the top screen.
In the electronic musical instrument 10, two display formats of a normal display and a simplified display are prepared for the top screen shown in FIG.

  Of these, the normal display is a display format that places importance on functionality, and is a display format that displays a large number of setting contents mainly for the purpose of accepting a setting change operation in the electronic musical instrument 10. In addition, the simplified display is a display format that emphasizes reference, and a part of information displayed on the screen of the normal display is mainly conscious of the purpose of referring to important setting contents during the performance of the electronic musical instrument 10. This is a display format in which the display is easier to see than the normal display.

  For example, the top screen 100 of the normal display shown in FIG. 3A includes a mode display 101 that displays the current operation mode, and a bank display 102 that displays the tone bank, tone number, category, and tone name currently in use. , A timbre number display 103, a category display 104, and a timbre name display 105, and a chorus display 106 and a reverb display 107 indicating on / off of a chorus effect and a reverb effect, respectively.

  The simplified display top screen 110 shown in FIG. 3 (b) displays the timbre number, category, and timbre name of the currently used timbre among the information displayed on the normal display top screen 100, with larger size characters. Timbre number display 113, category display 114, and timbre name display 115 to be displayed.

Here, only one type of the top screen 110 for simplified display is shown, but a plurality of types such as changing the type of parameter to be displayed or changing the type, size, color, or display position of the font while keeping the type of parameter constant. A top screen of various types of simplified display may be prepared.
In the electronic musical instrument 10, the top screen 100 for normal display and the top screen 110 for simplified display can be switched by a display switching instruction independent of the operation for screen transition shown in FIG.

FIG. 4 shows the relationship between screen transition and display switching.
First, in the electronic musical instrument 10, when a predetermined screen transition instruction is given during display of the top screen, the display is switched to the lower screen according to the instruction as described with reference to FIG.
The user can issue this screen transition instruction by, for example, pressing a button for calling a lower screen for detailed setting. Basically, as shown in FIG. 2, it is possible to instruct only a transition to a specific transition destination defined in advance for each screen. However, it is conceivable to prepare a button or command associated with a specific screen, and to jump directly to the associated screen by pressing the button or executing the command.

  On the other hand, in the electronic musical instrument 10, when a display switching instruction is given, the display format of the top screen displayed on the display is toggled between normal display and simplified display. When a plurality of types of simplified display top screens are prepared, the normal display top screen and the plurality of types of simplified display top screens can be switched to circulate in a predetermined order as shown in FIG. You should be able to do it. The user can issue this display switching instruction by, for example, simultaneously pressing a shift key and a cursor key. Alternatively, a selection button corresponding to each type may be provided so that a desired display format can be selected with a single touch, or can be selected from a menu pop-up displayed on the display.

The information on the type of display format specified by the display switching instruction is stored separately from the information indicating the position of the screen on the tree shown in FIG. 2 that is changed according to the screen transition instruction.
Further, the display switching instruction can be performed in the same manner regardless of which screen is being displayed. That is, the same operation can be performed during the display of the top screen and the display of the lower screen shown in FIG.

  However, in the electronic musical instrument 10, as shown in FIG. 2, only one type of normal display format is prepared for the lower screen other than the top screen, so the display switching process is performed while the lower screen other than the top screen is displayed. Even if is performed, the lower screen of the simplified display is not displayed, and the lower screen of the normal display remains displayed.

  In addition, when the display format is switched to the simplified display on the top screen with the simplified display, and then the screen transition instruction is given to change to the lower screen, the lower screen of the normal display is displayed instead of the lower screen of the simplified display. However, since information indicating that “simple display is performed” remains even in this state, when the display returns to the top screen again according to the screen transition instruction, the top screen is displayed in a simplified display (FIG. 4). (See arrow A).

Next, FIG. 5 shows a configuration example of screen data for one screen stored in the electronic musical instrument 10.
As shown in FIG. 5, the screen data includes a header, an arbitrary number of item data, and operation data. With respect to this format, there is no need to make a difference between the top screen and the lower screen, or normal display and simplified display.

  The header includes a screen ID, background data, the number of display items, a screen type, and a simplified display use flag. The screen ID is data defining the position of the screen on the tree shown in FIG. 2, the background data is data indicating the background color or background image of the screen, and the number of display items is the number of item data included in the screen data. In other words, the data indicating the number of items such as parameters and messages displayed on the screen, and the screen type is the normal display screen or the simplified display screen (if there are multiple types of simplified display, what type of simplified display? ) And simplified display use flag are data indicating whether or not to use simplified display on the screen of the corresponding screen ID. Among these, the simplified display usage flag is usage data.

Note that the value of the simplified display use flag can be determined independently of whether or not the data of the simplified display screen corresponding to the electronic musical instrument 10 is actually stored. For example, even if the data of the corresponding simplified display screen is stored, a value indicating that the simplified display is not used may be set. However, a value indicating that the simplified display is not necessarily used is set for the data of the normal display screen that does not store the corresponding simplified display screen data.
In the screen set S shown in FIG. 2, the simplified display screen data is prepared only for the top screen, and the other lower screens are not prepared. The simplified display use flag is set to OFF in the screen data of other lower screens.

  Each item data is data that defines a display area to be arranged on the screen and display contents thereof, and includes data of parameter ID, display position, display color, font type, and character size. The parameter ID is data indicating the type of parameter whose value is displayed in the display area, and the display position is data indicating the position of the display area. Note that fixed character strings such as parameter names and messages can also be displayed on the screen, and when this is displayed, an ID indicating the character string may be stored at the position of the parameter ID. The display color, font type, and character size are data that define the character color, font type, and size used for notation of parameter values and the like.

  The operation data is data that defines the contents of instructions specific to the screen to be received on the screen being displayed, and defines the contents of operations to be executed at the time of detection for each trigger event used as an instruction detection trigger. Examples of the trigger event include operation of an operator (including touching a predetermined area on the touch panel), elapse of a predetermined time, and the execution operation includes changing a parameter value or going to a screen with a specific ID. Transitions.

The instructions received by the electronic musical instrument 10 include instructions common to each operation mode or all operation modes, in addition to instructions specific to the screen, the contents of which are defined by data not shown.
Further, the above screen data is prepared separately for a normal display screen and a simplified display screen as well as a screen of another ID. On the other hand, the normal display and the simplified display of the screens that are at the same position on the tree shown in FIG. However, if the correspondence can be shown by another means, it is not hindered to assign a unique ID to the simplified display screen.

When a plurality of types of simplified displays are prepared, one screen data may be prepared for each type. However, if the items to be displayed are the same and only the font color, type, and size are different, one screen data to be used for multiple types of simplified display is prepared, and there is a difference for each type in the screen data. It is also possible to prepare only the portion of data for each type and share other data with a plurality of types of simplified display.
Further, the top screen in each operation mode may be specified by a screen ID in data (not shown) that defines the contents of the operation mode.

Next, FIG. 6 and FIG. 7 show processing executed by the CPU 11 of the electronic musical instrument 10 to display the screen described above.
FIG. 6 is a flowchart of processing according to the display switching instruction.
When detecting the occurrence of an event defined as a display switching trigger event (such as pressing a predetermined key), the CPU 11 starts the processing shown in the flowchart of FIG.

  In the process of FIG. 6, the CPU 11 first refers to the switching order shown in FIG. 4, the information of the display format corresponding to the operated button, and the display format after switching is normal display, 1 or Information on which type of display among the plural types of simplified display is acquired (S11). Thereafter, it is determined whether or not the simplified display use flag in the screen data of the screen being displayed on the display 18 is ON (S12).

If it is ON, it is determined that switching between normal display and simplified display is possible, and the contents of the display format register provided in the RAM 13 are changed to values indicating the display format after switching acquired in step S11. (S13).
Thereafter, a screen having a screen ID of the screen being displayed and having a display format indicated by the value of the display format register is drawn based on the screen data (S14), and the drawn screen is displayed on the display 18 (S15). The process ends.

  The screen data used for the processing in step S14 may be searched from the screen data set by the screen ID and the display format. The drawing process is a process of arranging a character image such as a parameter value or a message defined by each item data on a background image defined by the background data.

Through the above processing, during the display of the screen set to use the simplified display, the normal display and the simplified display can be switched according to the display switching instruction operation.
If NO in step S12, that is, if it is set that the simplified display is not used on the screen being displayed, the processing is ended as it is. Accordingly, not only the display is not switched but also the value of the display format register is not changed.

This is to avoid changing the value of the display format register without switching the display because it becomes difficult for the user to grasp the current value of the display format register.
However, this is not essential, and the value of the display format register may be changed as in step S13 even if NO in step S12.

Next, FIG. 7 is a flowchart of processing according to the screen transition instruction.
The CPU 11 detects the occurrence of an event (such as pressing a predetermined key or elapse of a predetermined time) defined as a screen transition trigger event in the screen data of the screen being displayed, or is common to each operation mode or all operation modes. When the occurrence of an event defined as a screen transition trigger event is detected, the processing shown in the flowchart of FIG.

  In the process of FIG. 7, the CPU 11 first refers to the screen data shown in FIG. 5 or refers to the data stored in association with other trigger events, so that the transition destination screen is displayed. A screen ID is acquired (S21). Thereafter, it is determined whether or not the simplified display use flag in the screen data of the transition destination screen is ON (S22).

  If it is ON here, it is understood that the simplified display is used on the transition destination screen, that is, it is possible to display a screen in a display format according to the contents of the display format register. The screen having the display format indicated by the value of the display format register is drawn based on the screen data (S23), the drawn screen is displayed on the display 18 (S25), and the process is terminated.

On the other hand, in the case of NO in step S22, it can be seen that the simplified display is not used on the transition destination screen. Therefore, the normal display screen having the screen ID of the transition destination screen is displayed regardless of the value of the display format register. Drawing is performed based on the screen data (S24), the drawn screen is displayed on the display 18 (S25), and the process is terminated.
The contents of the drawing process performed in steps S23 and S24 are the same as those in step S14 in FIG. 6 except for the image data search condition.

With the above processing, even when a transition instruction to a screen with a screen ID that does not use the simplified display is given while the simplified display screen is displayed, the user is not required to change the setting, and the setting change itself can be performed. The transition destination screen can be displayed in the normal display without being conscious.
In addition, when a transition instruction (for example, an instruction to return to the previous screen) to the screen ID using the simplified display is performed again from this state, the transition destination screen is the same as the previously selected display format. , Can be displayed simply. In other words, even if the screen transitions to a screen ID that does not use the simplified display, the value of the display format register is not cleared. Therefore, even if the display switching operation to the simplified display is not performed every time the screen transitions, Simplified display can be automatically performed on the screen with the screen ID using display.

Here, as for the simplified display, as shown in FIG. 2, it is preferable that the top screen can be used. This is because the top screen is often displayed during performance and is often a screen that displays the contents of the most important setting items.
On the other hand, since the lower screen is often a screen that accepts detailed item setting operations, it is not familiar with the simplified display that displays only a part of the items displayed in the normal display.

Under such circumstances, when the electronic musical instrument 10 described above is used, the top screen is displayed in a simplified display during performance, and the timbre information can be referred to at a glance. The user can move to the lower display screen to change the setting, and can return to the top screen of the simplified display and continue playing with only the screen transition instruction. Therefore, even when a simplified display is prepared only for a part of the screens, the simplified display screen can be efficiently used with a simple operation.
When the top screen is displayed in the normal display, the screen can be changed by the same operation to change the setting and return to the normal display top screen. Therefore, the operability during normal display is not deteriorated.

This is the end of the description of the embodiment, but it goes without saying that the configuration of the apparatus, the specific data format, the display content of the screen, the display format, the processing content to be executed, etc. are not limited to those described in the above embodiment. It is.
First, in the above-described embodiment, the example in which the simplified display is used only for the top screen has been described, but it is needless to say that the simplified display may be used for the lower screen.

The screen data for simplified display may be newly created and added by the user, or the existing screen data may be edited.
Further, for a screen on which data for simplified display is prepared, the user may be able to set whether or not to use simplified display, that is, the value of the simplified display use flag. Furthermore, the value of the simplified display use flag in the screen data of each screen may be automatically set in accordance with the presence or absence of the simplified display screen data.

  Also, it is not essential to prepare the simplified display use flag individually for each screen. For example, if the hierarchy can be defined in the tree structure of the screen as shown in FIG. 2, whether or not to use the simplified display is set for each hierarchy, and even if the screen data cannot be referred to, the simplified display can be performed using only the hierarchy information. It may be possible to determine whether or not it is used. Furthermore, when the simplified display is performed only on the top screen as in the example of FIG. 2, “whether or not the top screen is used” may be used as a criterion for determining whether or not the simplified display is used. That is, there is no problem in the operation of the above-described embodiment as long as it is possible to grasp which of the normal display screens the simplified display is used in any format.

In the above-described embodiment, the electronic musical instrument 10 that is particularly effective when the present invention is applied has been described as an example. However, the present invention is naturally applicable to other musical tone signal generating apparatuses. . For example, a sound source device that does not have a performance operator and generates a tone signal according to performance data supplied from the outside, a MIDI sequencer that generates a tone signal based on MIDI music data stored in advance, etc. The present invention is applicable.
The configurations and various modifications of the embodiments described above can be applied in appropriate combinations within a consistent range.

As is clear from the above description, according to the electronic musical instrument of the present invention, it is possible to appropriately refer to information of contents according to the situation by a simple operation.
Therefore, by applying this invention, an electronic musical instrument with high operability can be provided.
