The RAM 4 has a communication data memory area for storing various parameters related to communication, a communication buffer area used as a buffer at the time of communication, an edit buffer area used at the time of communication data editing, and the like. Also, RAM4
Is also used as a storage area such as a register or a flag used in an ordinary electronic musical instrument. Communication parameters stored in RAM4 (communication parameters)
It is necessary to keep the memory even when the power is turned off, so the RAM 4 is a battery backup RAM.

The electronic musical instrument of this embodiment includes a keyboard 6 for a user to perform, a keyboard interface 5 for connecting the keyboard 6 to a bidirectional bus line 14, a panel switch 8 such as a numeric keypad or a mode key. A panel switch interface 7 for connecting the panel switch 8 to the bus line 14, a display 10 for displaying various information, a display interface 9 for connecting the display 10 to the bus line 14, a sound source for generating a musical tone signal 11 and a sound system 12. 13
Indicates a speaker connected to the sound system. As the sound source 11, the sound system 12, and the like, any of those used in ordinary electronic musical instruments may be used.

FIG. 2 is an external view of the electronic musical instrument of this embodiment. In this figure, the same numbers as those in FIG. 1 indicate the same parts.

In FIG. 2, 21 is an EXIT key, 22 is a numeric keypad, 23 is an ENTER key, and 24 is a mode (M
ODE) key. 6a is the leftmost white key among the white keys of the keyboard 6, 6b is the leftmost black key among the black keys of the keyboard 6,
6c is the second white key from the left among the white keys of the keyboard 6.

The operation of the electronic musical instrument of this embodiment and the operation according to the operation will be briefly described with reference to FIG.

The electronic musical instrument of this embodiment has three modes. The first mode is a normal tone generation mode for normally generating a musical tone. The second mode is a communication mode for communicating with an external device. The third mode is a communication data edit mode for editing parameters used for performing communication.

First, when the power of the electronic musical instrument is turned on, a normal sound generation mode is set. The display 10 indicates that the current mode is the normal sounding mode. When the mode key 24 is pressed once from the normal sounding mode, the electronic musical instrument switches from the normal sounding mode to the communication mode. The display 10 displays a message indicating that the current mode is the communication mode. Further, when the mode key 24 is pressed, the electronic musical instrument switches from the communication mode to the communication data edit mode. The display 10 displays a message indicating that the current mode is the communication data edit mode. Further, when the mode key 24 is pressed, the electronic musical instrument switches from the communication data edit mode to the normal tone generation mode again. The display 10 indicates that the current mode is the normal sounding mode.

In the normal tone generation mode, a performance based on normal tone synthesis can be performed. That is, in the normal tone generation mode, when a key (keyboard key) of the keyboard 6 is pressed, a musical tone assigned to the key is generated.

In the communication mode, when a key on the keyboard 6 is pressed, information (communication data) such as the name and telephone number of the communication destination assigned to the pressed key is displayed on the display 10 without generating a tone. For example, the keys 6a, 6b, 6c and the like of the keyboard 6 are each assigned communication data such as the name of the communication destination and the telephone number in advance, and the names of the communication destinations assigned by pressing these keys are displayed. A phone number can be displayed. By pressing a new key, another communication destination can be displayed one after another.

In the electronic musical instrument of this embodiment, the keyboard 6 has 61 keys, so that 61 communication data can be allocated. By pressing the key of the keyboard 6 in this manner, a desired communication destination is displayed on the display 10 and the enter key 23 is displayed.
Is pressed to select and confirm the displayed communication destination. When the communication destination is selected and confirmed, the electronic musical instrument automatically calls and calls the selected communication destination. When the telephone line is successfully connected, data can be transmitted and received between the communication destination and the electronic musical instrument. Here, when a predetermined signal is exchanged with the communication destination and the user selects the data to be downloaded, the selected data is transferred from the communication destination device such as a computer to the electronic musical instrument. When the transfer ends normally, the transfer data temporarily stored in the buffer is transferred to the corresponding memory area.

In this state, if the mode key 24 is operated to set the normal performance mode, the received data can be confirmed. For example, if the received data is timbre data, the actually played timbre can be confirmed, or if the received data is performance data, an automatic performance can be performed based on the data to confirm the performance.

The communication data edit mode is a mode in which communication data used for the above communication is set for each key of the keyboard 6. The communication data that can be set includes, for example, the name of the communication destination, telephone number, own user ID (identification number), password, and other parameters specific to the communication system. As a method for editing these data, a conventionally known method may be used.

Next, the operation of the electronic musical instrument of this embodiment will be described in detail with reference to the flowcharts of FIGS.

First, registers and flags used in the electronic musical instrument of this embodiment will be described.

(A) MODE: a mode register indicating the current mode of the electronic musical instrument. When the value of the mode register is “0”, the normal tone generation mode, when “1”, the communication mode, and when “2”, the communication data edit mode, respectively.

(B) KN: a key number register for storing key numbers corresponding to various types of the keyboard 6 of the electronic musical instrument. Information that can specify various types of the keyboard 6 includes a key code assigned to each key, and the key number is obtained by subtracting a predetermined value α from the key code.

(C) KC: a key code register for storing various key codes of the keyboard 6. The key code that identifies each key is MIDI
This is a standard node code.

(D) CF: a connect flag indicating a connection state between the electronic musical instrument and an external device. Connect flag value is "0"
Indicates that the connection with the external device has not been made yet, and the value “1” indicates that the connection is established.

For the sake of convenience, in the following description, each register and the like will be represented by the same name.
That is, the “key number register KN” (or simply “key number”) represents the register and its contents.

Next, the overall processing operation of the electronic musical instrument of this embodiment will be described with reference to the flowchart of FIG. First, when the operation of the electronic musical instrument starts, in step 101, the register,
Initialize flags, buffers and other work areas. By this initialization, the mode register MODE is set to "0", the connect flag CF is set to "0", and the key number register KN is set to "1".

In step 102, the operation (on / off) of the key of the keyboard 6 is scanned. Next, in step 103, it is determined whether or not any key on the keyboard 6 has a key event. If there is a key event, the process branches to step 104, performs key processing, and proceeds to step 105. If there is no key event in step 103, the process directly proceeds to step 105.

In step 105, the operation (on / off) status of the panel switch 8 is scanned. In step 106, it is determined whether or not there is a panel event for the panel switch 8. If there is a panel event, step 10
The process branches to 7 and, after performing the panel processing, returns to step 102 again. If there is no panel event in step 106,
It returns to step 102 as it is.

Referring to FIG. 4, the key processing routine of step 104 in FIG. 3 will be described. In the key processing routine,
In step 201, it is determined whether or not the mode register MODE is "0", that is, whether or not the current mode is the normal sounding mode. If the mode register MODE is “0”, that is, if the normal sounding mode is set, the process branches to step 202. In step 202, normal sound generation processing (generation of a tone corresponding to the depressed key and sound end processing) is performed, and the process returns.

If the mode register MODE is not "0" in step 201, it is determined in step 203 whether an ON event of any key of the keyboard 6 has occurred. If the key is not turned on (pressed), the process returns. If the key is turned on, a value obtained by subtracting a predetermined value α from the key code KC of the key turned on in step 204 is stored in the key number register KN. This is, for example, a value of “0” to “127” that can be assigned as a key code, whereas an actual key may not have some keys on the low-temperature side. , And the key number of the leftmost key is set to “1”. This step 204
Thus, the key 6a in FIG. 2 is assigned a key number "1", the key 6b is assigned a key number "2", and the key 6c is assigned a key number "3".

Next, in step 205, the communication data corresponding to the key number KN in the communication data memory is referred to, and the communication data is displayed on the display 10. The displayed communication data includes information such as the name of the communication destination and the telephone number as described above. After step 205, the process returns.

Next, the panel processing routine of step 107 in FIG. 3 will be described with reference to FIG. In the panel processing routine, first, it is determined whether or not the panel switch operated in step 301 is the mode key 24. If the mode key is 24, the mode register MODE
The remainder obtained by dividing 1 by 1 and dividing by 3 is calculated and stored in the mode register MODE again. This allows the mode register
The value of MODE changes from “0” to
The switching is repeatedly performed in the order of “1” → “2” → “0”.

After changing the value of the mode register MODE in step 302, the display on the display 10 is rewritten to display the current mode in step 303. Thereafter, the process proceeds to step 304. If the mode key 24 has not been pressed in step 301, the process proceeds to step 304.

In step 304, the value of the mode register MODE is determined,
Branch to each process according to the current mode. When the mode register MODE is "0", that is, when the normal tone generation mode is set, a normal panel process is performed in step 305, and the process returns. If the mode register MODE is "1" in step 304, that is, if it is in the communication mode, step 30
After performing communication processing in step 6, the process returns. Step 304
When the mode register MODE is "2", that is, in the communication data edit mode, the communication data edit processing is performed in step 307, and the process returns.

Next, the communication data edit processing routine of step 307 in FIG. 5 will be described with reference to FIG. In the communication data edit processing routine, first, it is determined whether or not the key pressed in step 401 is the enter key 23. That is, the communication data to be edited is selected by pressing the key of the keyboard 6, and this selection is confirmed by pressing the enter key 23. In step 401, the press of the enter key 23 for confirming the selection of the communication data is detected. I do.
Thus, the user does not need to remember which key the communication data to be edited is assigned to, and presses the key appropriately to display the communication data, and when the communication data to be edited is displayed. By pressing the enter key 23, it can be selected and confirmed.

If the enter key 23 is not pressed in step 401,
Return as it is. If the enter key 23 has been pressed, the communication data stored at the position corresponding to the key number KN is read in step 402 and written to the edit buffer.

Next, in step 403, the communication data currently stored in the edit buffer and displayed on the display 10 is edited using the numeric keypad 22 or the like. The editing operation is continued until the exit key 21 or the enter key 23 is pressed. As the communication data to be edited here,
For example, there are a communication destination name, telephone number, own user ID (identification number), password, and other communication system-specific parameters (communication destination-specific data). The editing process performed in step 403 is a well-known method, and the description thereof is omitted. However, the event is detected by the panel switch 8 and the communication data displayed on the display 10 and edited in the edit buffer is edited based on the event. .

Next, in step 404, it is determined whether or not the exit key 21 has been pressed. This determination uses the result of the panel event detection in step 403. If the exit key 21 has been pressed in step 404, the communication data editing process is canceled and the process returns. At this time, since the editing process was performed on the edit buffer, the communication data stored in the communication data memory has not been rewritten. Therefore, when the communication data edit mode is accidentally entered or when the communication data to be edited is mistaken, the exit key 21
By pressing, it is possible to escape from the communication data edit mode without changing the data.

If the exit key 21 has not been pressed in step 404, it is determined in step 405 whether the enter key 23 has been pressed. This determination uses the result of the panel event detection in step 403. If the enter key 23 has not been pressed, the communication data is still being edited, so the process returns to step 403 to continue editing the communication data. If it is determined in step 405 that the enter key 23 has been pressed, the contents of the edit buffer edited in step 406 are written in a position corresponding to the key number KN in the communication data memory. Then, return.

Next, the communication processing routine of step 306 in FIG. 5 will be described with reference to FIG. In the communication processing routine, first, in step 501, the content of the connect flag CF is determined. If the connect flag CF is "0", it means that the line has not been connected yet, so that the communication is initialized in step 502, and the process returns.
If the value of the connect flag CF is "1" in step 501, it means that the line has been connected and a user ID, a password, and the like have been transmitted, so the routine returns after performing normal communication processing in step 503.

Next, the communication initial processing routine of step 502 in FIG. 7 will be described with reference to FIG. In the communication initial processing routine, first, at step 601, it is determined whether or not the enter key 23 is pressed. If the enter key 23 is not pressed, the process returns.

If the enter key 23 is pressed in step 601,
Since the user has selected the communication destination corresponding to the communication data currently displayed on the display 10,
In step 602, the modem 1 is initialized. Then, in step 603, the corresponding communication data is read from the communication data memory according to the current key number KN, and the telephone number of the communication destination is automatically called.

In step 604, a timer is initialized, and in step 605, it is determined whether or not a telephone line has been connected. The timer is for counting the call waiting time. If the telephone line has not been connected in step 605,
In step 606, the timer is checked, and it is determined whether or not the value of the timer exceeds a predetermined value. If the timer does not exceed the predetermined value, the flow returns to step 605 again to check the connection state of the telephone line.

If the value of the timer exceeds the predetermined value in step 606, the content of the error is displayed on the display 10 in step 610, then the telephone line is disconnected in step 611, and the routine returns.

If the telephone line is connected in step 605, an ID and a password are transmitted in step 607, and it is determined in step 608 whether the transmission has been normally performed. If the transmission has not been performed normally, the flow branches to step 610. If the transmission is normally performed in step 608, the value of the connect flag CF is set to "1" in step 609, and the process returns.

Next, the normal communication processing routine of step 503 in FIG. 7 will be described with reference to FIG. In the normal communication processing routine, first, in step 701, the exit key 2
It is determined whether or not 1 is pressed. Pressing the exit key 21 in the normal communication process corresponds to logoff (LOGOFF) of the communication line.

If the exit key 21 is not depressed in step 701, it means that a normal communication process is to be performed. Therefore, it is determined in step 702 whether data to be read has been selected. This process is a process of exchanging appropriate information between the user and the communication destination and selecting data to be received (downloaded) from the communication destination (data supply destination), but may be performed by a known method. For example, when the telephone line is connected, a list of data that can be selected from a communication destination computer or the like is transmitted to the electronic musical instrument of this embodiment, and the electronic musical instrument displays the data on the display 10. Then, the user may select the data he or she wants to receive from the list of data displayed on the display 10 in this step 702.

If data to be read has not been selected in step 702, the process returns. If the data to be read is selected, the data is received in step 703, and the received data is stored in the communication buffer. Then, in a step 704, it is determined whether or not the data reading is completed. If data reading has not been completed yet, it is determined in step 705 whether an overflow of the communication buffer has occurred. If no overflow has occurred, the flow returns to step 703 to continue data reception.

If an overflow of the communication buffer has occurred in step 705, the fact that an overflow error has occurred is displayed on the display 10 in step 707, the communication buffer is cleared in step 708, and the routine returns. On the other hand, if the data reading is completed in step 704, the received data stored in the communication buffer is transferred to the corresponding memory area in step 706, and the process proceeds to step 708.

If the exit key is pressed in step 701, the system is logged off in step 709 and the
Then, "0" is stored in the connect flag CF, and after the telephone line is disconnected in step 711, the process returns.

Next, the flow of the processing sequence when the user performs some typical operations will be described.

For example, if the mode is the normal sounding mode immediately after the power of the electronic musical instrument is turned on, when the user presses the key of the keyboard 6, the processing sequence is changed from step 102 to 103 to 10
4 (steps 201 → 202 in FIG. 4) → 105 → 106 → 102, and a normal tone is generated at the distance of step 202 in FIG.

When the user selects any communication destination, the user first presses the mode key 24 once to shift the mode from the normal sounding mode to the communication mode. The processing sequence at this time is as follows: steps 102 → 103 → 105 → 106 → 107 (steps 301 → 302 → 303 → 304 → 306 in FIG. 5 (steps 501 → 502 in FIG. 7 (steps 601 → return in FIG. 8)). ) → Return) → Return) → 102. Here, no processing is performed except for the mode switching.

Next, the user presses the key of the keyboard 6 to confirm the communication destination.
For example, if the user presses the key 6a of the keyboard 6, the processing sequence is step 102 → 103 → 104 (step 201 → 203 → 204 → 205 → return in FIG. 4) → 105 → 106 → 102
Proceed like. Here, the communication destination assigned to the key 6a of the keyboard 6 and its telephone number are displayed on the display 10.

The user confirms this on display 10, and if the communication destination to be communicated with is different from the currently displayed communication destination,
Press another key (for example, keys 6b and 6c). The processing sequence at this time is the same as when the key 6a is pressed. However, since the key number KN is different for each key, the communication destination is displayed separately in step 205.

When the communication destination desired by the user is displayed on the display 10, the user presses the enter key 23 there. The processing sequence at this time is step 102 → 103 → 105 → 106
→ 107 (Step 301 → 304 → 306 in FIG. 5) (Step 501 → 502 in FIG. 7 (Step 601 → 602 → 603 → 604 → FIG. 8)
605 → 607 → 608 → 609 → return) → return) → return) → 102. However, the above flow assumes that transmission of the line connection, ID password, and the like has been normally performed. When the telephone line is connected in this manner, a list of data that can be selected from the computer at the communication destination is transmitted to the electronic musical instrument, and the list is displayed on the display 10. The user selects the data he wants to receive from the displayed list.

The processing sequence for performing this selection operation is as follows: steps 102 → 103 → 105 → 106 → 107 in FIG. 3 (steps 301 → 304 → 306 in FIG. 5 (steps 501 → 502 in FIG. 7 (FIG. 9)). Step 701 → 702 → 703 → 704 → 706 → 708 → Return)
→ Return) → Return) → 102. Here, it is assumed that all data has been received normally without errors such as overflow of the communication buffer. As described above, data is received from the communication destination computer or the like.

Thereafter, the user presses the exit key 21 to release the communication state. The processing sequence at this time is as follows: steps 102 → 103 → 105 → 107 in FIG. 3 (steps 301 → 3 in FIG. 5).
04 → 306 (Step 501 → 503 in FIG. 7 (Step 701 → 709 → 710 → 711 → Return) → Return) → Return) → 102.

When the user wants to edit the data of the communication destination assigned to each key of the keyboard 6, the operation of the mode key 24 first sets the communication data edit mode. The processing sequence at this time is as follows: steps 102 → 103 → 105 → 106 → 10 in FIG.
7 (step 301 → 302 → 303 → 304 → 307 (FIG. 6, step 401 → return) → return) → 102.

Next, the user presses any key of the keyboard 6 to display data of a communication destination to be edited on the display 10.
The processing sequence at this time is as follows: Step 102 → 1 in FIG.
It proceeds in the order of 03 → 104 (step 201 → 203 → 204 → 205 → return in FIG. 4) → 105 → 106 → 102. The user repeats this process and displays the data of the
Display on 10.

When the communication destination data to be edited is displayed on the display 10, the user presses the enter key 23. The processing sequence at this time is as follows: steps 102 → 103 → 105 in FIG.
→ 106 → 107 (steps 301 → 304 → 307 in FIG. 5 (steps 401 → 402 → 403 in FIG. 6)) and step 4
It reaches 03. In step 403 of FIG. 6, data editing is performed using the display 10 and various panel switches.

To rewrite the edited data, the enter key 23 is pressed in step 403. At this time, the processing sequence proceeds as steps 403 → 404 → 405 → 406 → return, and the edited data is assigned to the key again. As described above, the communication destination data of each key can be edited.

In the above embodiment, the communication destination is selected using the keys of the keyboard. However, not only the keyboard but also other operators may be used. For example, the selection may be made in the same manner by a tone color switch. Further, the communication destination is selected by using software, but all of them can be realized by a hardware configuration. Furthermore, an example in which data is downloaded (received) from a communication destination computer or the like has been described, but data may be uploaded (transmitted). In the above embodiment, the description of the operation of selecting the data to be read is omitted, but the data to be read may be selected using, for example, the ten keys 22 or the keyboard 6. Although the communication method using a telephone line has been shown, it is not limited to this,
(Local area network).

[Effects of the Invention] As described above, according to the present invention, a communication destination is selected using an operator such as a keyboard conventionally provided in an electronic musical instrument, and data is transmitted / received to / from the selected communication destination. Is performed, the connection operation with the communication destination is easy, and access to many communication destinations can be realized quickly and accurately. In addition, communication can be controlled from the electronic musical instrument main body.
