2. Description of the Related Art In recent years, electronic musical instruments have been known which are capable of independent performance using a keyboard and have an automatic performance function of generating musical tones based on pre-stored performance data.

[0003] Such electronic musical instruments generally have a display device composed of, for example, an LCD in order to display various messages to the operator, the status of the electronic musical instrument, etc. (hereinafter simply referred to as "messages, etc."). There is.

[0004] For example, as shown in FIG. 5(A), there is a device that displays an operation method on a display and displays a message or the like urging the operator to perform an operation. In the case of the example, "1 to 2
This prompts the operator to select one from the numbers "0".

Furthermore, as shown in FIG. 5(B), there is a device that displays the name of the currently selected tone color. In the illustrated example,
This means that piano is selected as the tone and the tempo is "120".

[0006] As described above, on the display of a conventional electronic musical instrument, messages and the like are displayed in a specific language, for example, English. Therefore, for people in countries and regions where the language is different, for example, people in countries and regions who do not understand English, the message becomes incomprehensible, which poses a problem in practical use.

[0007] In order to solve this problem, a manual is published in which the messages displayed on the display are translated into the language of the country or region where the electronic musical instrument is used, and the meaning of the messages etc. is communicated to the performer. It is known that this was done.

However, during actual performance, it is difficult and impractical to perform while viewing the manual.

[0009] Therefore, electronic musical instruments have been developed in which messages and the like are written in the language of the country or region in which the electronic musical instrument is used. Such an electronic musical instrument has the advantage that the person using the electronic musical instrument can easily understand messages and the like, and can perform smoothly.

However, messages etc. are generally
Since the data is stored in read-only memory (ROM), electronic musical instrument suppliers must develop individual ROMs for multiple languages, which lengthens development time and increases costs. It had the disadvantage of rising.

[0011] Furthermore, the language-specific ROMs have to be installed depending on the shipping destination of the electronic musical instrument, which has the disadvantage that the management work becomes complicated and time-consuming.

0012

[Problems to be Solved by the Invention] This invention has been made in view of the above circumstances, and allows the user of an electronic musical instrument to display messages, etc. in the desired language, and also reduces the time needed to develop a memory for messages, etc. It is an object of the present invention to provide a display control device for an electronic musical instrument that can be used at a low cost and that can easily manage the memory.

[0013]

[Means for Solving the Problems] The present invention provides a display means for displaying predetermined information, and a storage means for storing display information in a plurality of languages corresponding to the predetermined information to be displayed on the display means. and a setting means for setting a language to be used for display, and a control means for reading display information from the storage means and displaying it on the display means according to the language set by the setting means. do.

[0014]

[Operation] According to the present invention, display information in a plurality of languages corresponding to predetermined information to be displayed, such as a message, is stored in advance in the storage means, and when the language to be used for display is specified by the setting means, The subsequent display is such that a message or the like is displayed by reading the display information in the language specified by the setting means from the storage means and sending it to the display means.

[0015] In this way, display information in a plurality of languages for a predetermined message etc. is stored in one storage means, and the message etc. is displayed in the language based on the display information specified by the setting means. It is sufficient to prepare only one type of storage means. Therefore, the display information to be stored in the storage means can be developed in a short period of time, and the mass production effect makes it possible to supply the display information at a low price. Furthermore, one type of storage means can be applied to all electronic musical instruments in the same way, making management work easier.

Furthermore, the display device 15 is composed of, for example, an LCD, and displays the status of the electronic musical instrument, guidance information associated with various switch operations, and other messages based on information sent from the CPU 16. be done.

16 is a central processing unit (CPU), R
Each section of the electronic musical instrument is controlled according to a control program stored in a program memory section (not shown) of the OM 19.

The CPU 16 implements an automatic performance section 17 and a tone control section 18 as its software functions.

[0031] The automatic performance section 17 is operated by the ST
It is activated when an ART switch (not shown) is pressed to instruct automatic performance start. The automatic performance section 17 reads performance data from the ROM 19 and supplies it to the musical tone control section 18.

The musical tone control section 18 uses the data sent from the automatic performance section 17 or the keyboard 10 and the operation panel 11.
The information necessary for generating musical tones is calculated based on the data sent from the musical tone generator 21, and is supplied to the musical tone generating section 21.

A read-only memory (ROM) 19 stores display control data directly related to the features of the present invention. The ROM 19 includes, in addition to the display control data, a control program for operating the CPU 16, tone data, and other various fixed data (none of which are shown).

The above display control data is stored in the ROM 19 in the format shown in FIG. That is, the ROM 19 stores display control data consisting of a "tone color list,""rhythm name list," and "message list" for each language used by the electronic musical instrument.

As shown in the example, the "tone list" stores, for example, the name of a musical instrument representing the tone.

The "rhythm name list" stores rhythm names indicating the type of rhythm.

The "message list" stores words used by the electronic musical instrument to notify the operator of various information.

20 is random access memory (RAM)
It is. In this RAM 20, a work area for the CPU 16 and areas for various other registers, flags, etc. are defined.

Further, a part of this RAM 20 is a non-volatile RAM 20a with power backup. This RAM 20a stores identification information indicating the language used for display by the electronic musical instrument, and its contents are rewritten using the identification setting switch 25 and the numeric keypad 12, as will be described later.

The musical tone generator 21 stores musical waveform data and envelope data corresponding to the tone in the waveform memory 2 in accordance with data output from the musical tone controller 18 of the CPU 16.
2, an envelope is added to the read musical waveform data, and the result is output as a musical tone signal. The musical tone signal outputted from this musical tone generating section 21 is supplied to an amplifier 23.

As described above, the waveform memory 22 stores musical waveform data and envelope data corresponding to each timbre.

The amplifier 23 amplifies the musical tone signal supplied from the musical tone generator 21 with a predetermined gain and supplies it to the speaker 24. The speaker 24 is a well-known device that converts electrical signals into acoustic signals.

[0043] The above keyboard 10, operation panel 11, ROM 1
9, CPU 16, and RAM 20 are connected to the system bus 30
are connected to each other.

Next, the operation of the embodiment of the present invention in the above configuration will be explained with reference to the flowchart shown in FIG.

When the electronic musical instrument is powered on, first, as shown in FIG. 3, a tone generator initialization process is performed (step S10). This sound source initialization process is a process that sets the internal state of the musical tone generator 21 to an initial state to prevent unnecessary sounds from being generated when the power is turned on.

Next, RAM initialization processing is performed (
Step S11). This RAM initialization process
This is a process of clearing the contents of 0 or setting an initial value in a predetermined register or the like.

Note that in this RAM initialization process, the RAM
The non-volatile RAM 20a in 20 is not initialized,
The original content of the identification information is maintained.

Next, key processing is performed (step S1
2). In this key processing, sound generation/mute processing is performed in accordance with key press/release of keys on the keyboard 10. The operation of this key processing is well known and has no direct relation to the gist of the present invention, so a detailed explanation will be omitted.

Next, panel scan processing is performed (
Step S13). That is, the on/off state of each switch detected by the panel scan circuit of the operation panel 11 is C.
The data is read into the PU 16 and stored in a predetermined area of the RAM 20.

[0050] Next, it is checked whether there is an on event for the switch on the operation panel 11 (step S14).
. This compares the on/off state of each switch (stored in the RAM 20) that was fetched from the operation panel 11 last time with the on/off state of each switch that was fetched from the operation panel 11 this time. This is done by checking whether there is a switch that has changed.

If it is determined that there is no on-event, the process branches to step S27 and automatic performance processing is performed.

On the other hand, when it is determined that an on event has occurred, the turned on switch is the tone selection switch 13.
It is checked whether it is (step S15).

When it is determined that the timbre selection switch 13 has been turned on, timbre setting processing is performed (step S16). This tone setting process is a process of shifting the electronic musical instrument to a tone setting mode.

Next, display information read address setting is performed (step S17). This refers to the identification information stored in the nonvolatile RAM portion 20a of the RAM 20, generates the address of the ROM 19 in which the "tone list" of the language to be used for display is stored, and sets it in a predetermined area of the RAM 20. It is processing.

Next, display information output processing is performed (
Step S18). That is, the "tone list" information is read from the ROM 19 using the address set in step S17 above, and a process is performed to send it to the display 15 of the operation panel 11.

As a result, for example, as shown in FIG. 4B, if the identification information stored in the nonvolatile RAM portion 20a of the RAM 20 is identification information A (displayed in language A), the tone name in English is The identification information B is displayed.
(Display in language B), the tone color name is displayed in Japanese. Although the figure shows only a portion of the display example, the entire tone color list is actually displayed. Thereafter, the operator uses the numeric keypad 12 to select a desired tone.

[0057] When this display information output processing is completed, the process branches to step S27, and automatic performance processing is performed.

If it is determined in step S15 that the turned-on switch is not the timbre selection switch 13, it is checked whether the turned-on switch is the identification setting switch 25 (step S19).

When it is determined that the identification setting switch 25 has been turned on, identification information setting processing is performed (step S20). That is, the electronic musical instrument enters the identification information setting mode. In this state, the operator presses the numeric keypad 12.
Select the desired identification information using . The selected identification information is then stored in the nonvolatile RAM portion 20a of the RAM 20.

[0060] When this identification information setting process is completed, the process branches to step S27, and automatic performance processing is performed.

If it is determined in step S19 that the turned-on switch is not the identification setting switch 25, it is checked whether the turned-on switch is the demonstration performance switch 14 (step S21).

When it is determined that the demonstration performance switch 14 has been turned on, display information read address setting is performed (step S22). This is RAM20
With reference to the identification information stored in the non-volatile RAM portion 20a of the R
This is a process of setting in a predetermined area of AM20.

Next, display information output processing is performed (
Step S23). That is, the "message list" information is read from the ROM 19 using the address set in step S22 above, and a process is performed to send it to the display 15 of the operation panel 11.

As a result, for example, as shown in FIG. 4A, if the identification information stored in the nonvolatile RAM portion 20a of the RAM 20 is identification information A (displayed in language A), a message is displayed in English. If the identification information is B (display in language B), a message is displayed in Japanese. Note that the figure shows only a part of the display example. After this, the operator presses the numeric keypad 12.
The desired demo performance piece is selected using the .

[0065] When this display information output processing is completed, the process branches to step S27, and automatic performance processing is performed.

If it is determined in step S21 that the turned-on switch is not the demo performance switch 14, it is checked whether the turned-on switch is one of the ten keys 12 (step S24).

Then, when it is determined that any one of the numeric keys 12 is turned on, numeric key processing is performed (
Step S25). That is, if the CPU 16 is in the timbre selection mode, it recognizes the timbre corresponding to the pressed switch on the numeric keypad 12, and sends data for generating a musical tone of that timbre to the musical tone generating section 21. In addition, in the identification setting mode, the identification information corresponding to the pressed switch in the numeric keypad 12 is recognized, and the identification information is stored in the RAM 2.
0 nonvolatile RAM section 20a.

Furthermore, in the demo performance selection mode, the demo performance song corresponding to the pressed switch on the numeric keypad 12 is recognized, and the selected demo performance is started.
Predetermined data processing is performed. In the demonstration performance, when a START switch (not shown) is pressed to enter automatic performance mode, reading of performance data from the ROM 19 is started, and automatic performance is started.

If it is determined in step S24 that the turned-on switch is not the numeric keypad 12, processing corresponding to the depression of the other switch is performed (step S26). For example, effect selection processing, volume change processing, etc. will be performed.

Next, automatic performance processing in step S27 is performed. This automatic performance processing itself is not directly related to the gist of the present invention, so a description thereof will be omitted.

When the automatic performance process is completed, the process returns to step S12, and the same process is repeated again.

By repeating this, if the automatic performance mode is selected, the selected song will continue to be automatically played, and if not, the musical tone will be played using the previously selected tone by key processing (step S12). will occur.

As described above, according to this embodiment, display control data in a plurality of languages corresponding to messages to be displayed are stored in advance in the ROM 19, and the language used for display is selected by the identification setting switch 25. Once identified, it is stored in the nonvolatile RAM 20a as identification information. In subsequent display operations, the identification setting switch 25
The display control data of the language set in is read from the ROM 19 and sent to the display 15 to display messages and the like.

In this way, display control data in multiple languages for a predetermined message etc. is stored in one ROM 19, and the message etc. is displayed in the language based on the display control data set by the identification setting switch 25. Therefore, it is sufficient to prepare only one type of ROM 19. Therefore, the display control data to be stored in the ROM 19 can be developed in a short period of time, and the mass production effect makes it possible to supply the display control data at a low price. Furthermore, one type of ROM 19 can be applied to all electronic musical instruments in the same way, making management tasks easier.

In the above embodiment, a case has been described in which a timbre list, a rhythm name list, and a message list are provided as display control data stored in the ROM 19, but data other than the above may also be stored.

Further, in the above embodiment, the identification information is stored in the non-volatile RAM, but the identification information may be stored depending on the set state of a switch, for example. In this case, the set state of the switch will be referred to as necessary.

Furthermore, it goes without saying that various modifications can be made without departing from the gist of the present invention.

[0078]

[Effects of the Invention] As detailed above, according to the present invention, messages, etc. can be displayed in the language desired by the user of an electronic musical instrument, and the development period for a memory for messages, etc. can be shortened, resulting in a low cost. In addition, it is possible to provide a display control device for an electronic musical instrument that can easily manage the memory.
