Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic musical instrument, and more particularly to an electronic musical instrument having improved means for selectively supplying parameter information for setting characteristics of musical tones such as tone colors.

[Conventional technology]

Generally, in electronic musical instruments, a tone color selection switch is provided separately for each selectable tone color, and similarly, a selection switch is provided separately corresponding to various effects and other musical tone characteristic setting factors. Therefore, the number of tones, effects, and other musical tone characteristic setting factors that can be selected for the electronic musical instrument is
Since the number of selection switches provided on the operation panel surface is limited, if the number of selection switches is to be increased, the number of selection switches must be increased accordingly, resulting in higher cost and securing a space for arranging switches. It becomes difficult to do so, and the operability may be impaired. For example, when a tone color is switched during playing on a keyboard, it may happen that the desired tone color selection switch cannot be operated quickly and another switch is operated by mistake.

In view of the above points, an electronic musical instrument has been proposed in which the number of switches and the like for selecting information for setting various musical tone characteristics can be reduced compared to the number of selectable information (for example, Japanese Patent Application No. 60-17602). In such a conventional electronic musical instrument, it is possible to selectively assign one of a plurality of timbres to a predetermined switch in the assignment mode, and it is assigned by operating the switch in the performance mode. A tone is selected. Switching between the allocation mode and the performance mode is performed by operating a dedicated selector switch.

[Problems to be solved by the invention]

Since the conventional electronic musical instrument as described above is provided with a dedicated changeover switch for switching between the allocation mode and the performance mode, it is necessary to perform a sufficient switch operation when performing the allocation operation. For example, when changing the assignment while playing on the keyboard, operate the mode select switch to change from the play mode to the assign mode, and then perform the selection operation to select the desired tone to be assigned to the predetermined switch, and then change the mode. It is necessary to perform a series of operations of operating the switch to return from the allocation mode to the performance mode. Therefore, there is a possibility that the keyboard performance may be hindered. Further, since the mode changeover switch must be provided, the cost is increased accordingly, and an extra switch arrangement space on the panel surface has to be secured.

The present invention has been made in view of the above point, and selects desired information from a plurality of parameter information to an information supply unit that supplies parameter information for setting the characteristic of a musical sound in response to operation of a switch. When assigning
It is an object of the present invention to provide an electronic musical instrument capable of performing allocation processing without providing a special mode changeover switch.

[Means for solving problems]

In the electronic musical instrument according to the present invention, parameter information for setting the characteristic of a musical sound is assigned, and the information supplying means for supplying this information according to the operation of the switch and the desired information from a plurality of parameter information are selected. When the parameter information is selected by the selecting means in this state, the parameter information can be automatically assigned in response to the operation of the switch and the selecting means. It is characterized by comprising an assigning means for assigning to the information supplying means, and a tone forming means for forming a tone signal having a characteristic set by this information based on the parameter information supplied by the information supplying means. The functional block diagram shows this first
It looks like the figure. Reference numeral 10 is an information supplying means, 11 is a selecting means, 12 is an allocating means, and 13 is a tone forming means.

[Action]

Arbitrary parameter information for setting the characteristic of the musical tone is assigned to the information supplying means 10, and the assigned information is supplied to the musical tone forming means 13 in response to the operation of the switch. In response to the operation of the same switch, the assigning means 12 automatically enters the assignable mode, and when the selecting means 11 selects the desired parameter information, this information is assigned to the supplying means 10 (assignment content). Will be changed).

〔The invention's effect〕

Therefore, according to the present invention, a special mode changeover switch for changing over to the allocation mode is not required, and it is possible to save extra switch operation time and save cost and switch arrangement space. In particular, when changing the assignment contents during musical tone performance, it is advantageous because the operation can be simplified by omitting extra switch operation.

<Description of Program> Next, an example of a program executed by the microcomputer will be described with reference to FIGS. 7 to 17.

FIG. 7 is a flowchart of the main routine. After the power is turned on, the contents of various registers in the RAM 29 are initialized. Next, the scanning process S1 of the tone color switch section 22 is performed. Here, any of the tone color switches TCSW1 to
8 is detected, the tone color switch on event subroutine of FIG. 8 is executed.

Next, processing S2 for detecting that the external memory 31 has been inserted into the interface 32 is performed. If it is detected that the external memory has been inserted, the pack insertion event subroutine of FIG. 9 is executed.

Next, the scanning process S3 of the multi-menu switch unit 23 is performed. Here, the menu up switch MUP
11 is executed, the subroutine shown in FIG. 11 is executed. When the menu down switch MDW on event is detected, the subroutine shown in FIG. 12 is executed and the data up switch DUP on event is detected. Then, the subroutine of FIG. 13 is executed, and when the ON event of the data down switch DDW is detected, the subroutine of FIG. 14 is executed and when the ON event of the enter switch ETR is detected, the subroutine of FIG. The subroutine is executed.

Next, the scanning process S of the registration switch unit 24.
Do 4. Here, when any on event of the registration switch REGSW is detected,
The subroutine shown in FIG. 10 is executed. When the on-event of the from pack switch FPSW is detected, the subroutine of FIG. 16 is executed and the confirmation switch CFS is executed.
When the W on event is detected, the subroutine of FIG. 17 is executed.

Next, the other operation part 25 related to the multi-menu
The scanning process of No. 1 is performed, and the scanning process of the other operation unit 26 is performed. Next, the processing related to the voice parameter creating device 33 is performed. In this process, the voice parameters created according to the player's preference are written in the RAM 29 as voice parameters TCPW (65) to TCPW (72). Finally, the scanning process of the key switch circuit 20 is performed, and the tone-assignment process to each channel is performed based on the scanning result.

The tone color switch-on event subroutine of FIG. 8 will be described.

First, the number of the turned-on tone color switch (one of TCSW1 to 8) is stored in the TCSW register, and then the LED corresponding to the turned-on tone color switch is turned on. Next, it is checked whether the number stored in TCSW is 7 or more (step 38). If it is 7 or more, the white switch TCSW7 or TCSW8 is turned on, and if it is less than 7, the normal tone color switches TCSW1 to TCSW6 are turned on.

If the white switch is turned on, the process proceeds to step 39, and the multi-menu number of the register MMNO is set to "1".
Set to. In step 40, the white switch assigned tone color code register WHTC (7) corresponding to the switch number (7 or 8) stored in the register TCSW.
Alternatively, the tone color code stored in the WHTC (8) (which is indicated by WHTC (TCSW)) is read and given to the multi-menu display tone color code register TCCODE. At step 41, the tone color code stored in TCCODE is referred to, and the tone color name corresponding to the tone color code is displayed on the multi-menu display 37. At this time, the display contents of the display 37 are as illustrated in the block of step 41. In this display, "VOICE, M
"ENU" is a menu display corresponding to the multi-menu number MMNO = "1", and the multi-menu switch unit 2
3 is a mode for functioning as a means for selecting a tone color to be assigned to the white switch.
The lower display shows the tone color name corresponding to the TCCODE tone color code. In the example in the figure, the tone color code is "01".
And the corresponding tone color name is "STRINGS1". Therefore, the lower display changes depending on the contents of TCCODE. By this processing, the tone color name of the tone color currently assigned to the turned-on white switch TCSW7 or TCSW8 is displayed on the multi-menu display 37.
In step 42, voice parameters (TCPW (1) to TCPW (7) corresponding to the TCCODE tone color code are transmitted.
2), which is TCPW (TCCOD)
(Denoted by E)) is read from the internal RAM 29 or ROM 30 and supplied to the tone generation circuit 34 (denoted by TG). As a result, the tone color of the tone signal generated by the tone generating circuit 34 is set according to the voice parameter assigned to the turned-on white switch.

If the turned-on tone color switch is not the white switch, the process proceeds from NO in step 38 to step 43 to reset the contents of the register MMNO to "0". In the next step 44, it is any one of the voice parameters (TCP (1) to TCP (6)) corresponding to the number of the on switch (any of 1 to 6) stored in the TCSW. TCP (denoted by TCSW) is read from the ROM 30 and supplied to the tone generation circuit 34.

The pack insertion event routine of FIG. 9 will be described. When it is detected that the external memory 31 is inserted,
"2" is set in the multi-menu number register MMNO (step 45). Next, the pack code is read from the memory PKCODE of the inserted external memory 31. In step 47, information for identifying the type of the external memory pack is displayed on the display 37 according to the read pack code. At this time, the display contents of the display 37 are as illustrated in the block of step 47. In this display, "RAM PACK" in the upper row indicates that the external memory pack is composed of readable and writable RAM, and "-REGIST &VOICE-" in the lower row indicates that the types of parameter information stored in the external memory pack are registration data and voice parameters. It shows that both. if,
When the external memory pack is composed of ROM, the upper display is "ROM PACK". Further, when the stored parameter information is only the registration data, the lower display is "-REGIST-", and when only the voice parameter is "-VOICE-". In this example, R
The types of the AM type external memory packs are the above-mentioned three types, and the identification information displayed on the display 37 is as shown in FIGS. 18 (a), (b) and (c). In this way, the display of the information for identifying the external memory pack is automatically displayed when the pack is attached to the electronic musical instrument without requiring a special switch operation.

The registration switch on event routine of FIG. 10 will be described.

First, the registration switch REGS turned on
The W number is stored in the register REGNO (step 48). Next, in step 49, the memory switch MSM
Check if is being turned on. If YES, the process proceeds to step 50 to write one set of registration data, but if NO, steps 51, 5
Proceed to step 2 to read a set of registration data. In step 50, the setting states of predetermined switches and operators in the panel section 21 to be incorporated in the registration data are one of a set of registration data (RMEM (1) to RMEM (16), and are numbered 1 to 1. Since 16 is designated by REGNO, this is written in the registration data memory of the RAM 29 as RMEM (REGNO).

In step 51, the LED corresponding to the turned-on registration switch REGSW is turned on. In the next step 52, the registration data RMEM (REGNO) corresponding to the registered registration switch number stored in the register REGNO is stored in the RAM 29.
Then, the setting state display of predetermined switches and controls on the panel unit 21 is controlled according to the contents of the registration data, and the setting contents of the registration data are clearly shown to the performer. In step 53, the parameter information corresponding to the read resist data RMEM (REGNO) is supplied to the tone generation circuit 34. In this way, various musical tone characteristics are set in a preset manner according to the selected registration data.

The programs shown in FIGS. 11 to 17 will be described below according to their functions.

<Tone Color Assigning Function to White Switch> When the white switch TCSW7 or 8 is turned on, the multi-menu number MMNO becomes "1" by the processing in step 39 (FIG. 8) described above. In this state, the voice parameter of the tone color assigned to the white switch is supplied to the tone generation circuit 34 to set the tone color of the tone signal generated therein, and another tone color is newly assigned to the white switch. Becomes automatically in mode. The main flow of information at this time is shown in FIG.

As already described in steps 38 to 42 of FIG. 8, when the white switch TCSW7 or 8 is turned on, the corresponding white switch tone color code register WHTC
The tone color code currently assigned thereto is read out from (7) or (8) and stored in the multi-menu tone color code register TCCODE. TCCODE
One of the voice parameters T according to the tone code of
CPW (1) to TCPW (72) are read out and supplied to the tone generation circuit 34, and the tone color name is displayed on the multi-menu display 37. This is the flow of reading voice parameters.

In this mode, the TCCOD is activated according to the operation of the menu up switch MUP or the menu down switch MDW.
By changing the contents of E, the voice parameter TC
A desired tone color is selected from 72 types of tone colors corresponding to PW (1) to TCPW (72) (the selected tone color is displayed on the display 37), and at the same time, the register WHTC (7).
Alternatively, the timbre assigned to the white switch can be changed by rewriting the memory of (8) with the contents of TCCODE.

Explaining the flow in this allocation mode, when the menu up switch MUP is turned on, YES in the routine of FIG. 11 (MMNO =
1), the value of the tone color code of TCCODE is incremented by 1 in step 55. Since the maximum value is 72, when the added value exceeds 72, the minimum value 1 is restored.
In the next step 56, the register WHTC corresponding to the white switch whose TCCODE tone color code has been turned on.
Register (assign) to (TCSW). Next step 5
7, voice parameters TCPW (1) to TCPW
The voice parameter TCPW (TCCODE) corresponding to the tone color code of TCCODE is read out from (72), and the tone color name is displayed on the display 37. Step 58
Then, the voice parameter TCPW (TCCODE) is supplied to the tone generation circuit 34.

The routine of FIG. 12 executed when the menu down switch MDW is turned on is almost the same as that of FIG. 11, except that step 55a corresponding to step 55 is different. In this step 55a, the value of the tone color code of TCCODE is decremented by 1. Since the minimum value is 1,
When the subtracted value is less than 1, the maximum value 72 is restored.

<Function when External Memory Pack is Inserted> When the external memory pack is inserted, the MMNO becomes “2” by the processing of step 45 (FIG. 9) described above. At this time, it is already described that the information for identifying the external memory pack is displayed on the display 37.

When the confirmation switch CFSW or the from pack switch FPSW is turned on when MMNO = 2, the content of the multi-menu number register MMNO is changed to "3", and the desired bank number is designated using the multi-menu switch unit 23. It becomes the mode that can do. The bank number is designated by operating the data up switch DUP or the data down switch DDW.

When the from-pack switch FPSW is turned on when MMNO = 2, step 59 in FIG. 16 becomes YES and MMNO is set to "3" in step 60.
In the next step 61, the bank number register BANKN
"1" is set to O as an initial value. Next step 6
2, the identification information corresponding to the pack code stored in PKCODE is displayed on the upper stage of the display 37, and BANK is displayed.
The bank number stored in NO is displayed at the bottom of the display 37. An example of the display contents of the display 37 is shown in the block of step 62. It should be noted that X in the figure showing the display contents on the display 37 indicates an appropriate numerical value according to the contents of the bank number register and an appropriate character according to the contents of the pack code register.

When the confirmation switch CFSW is turned on when MMNO = 2, the same processes as steps 59 to 62 in FIG. 16 are performed by the processes in steps 59a to 62a in FIG.

Even if MMNO = 2, the mode is other than parameter editing (when the value of MMNO is 19 or more, the multi-menu is used for purposes other than parameter editing).
Is set to MMNO = 3 through the YES route of steps 177 and 177a (FIGS. 16 and 17).

In the state of MMNO = 3, the value of BANKNO is changed by operating the switches DUP and DDW. When the data up switch DUP is turned on, the process proceeds from YES to step 63 in FIG. 13 to step 64, where BANK
Increase the bank number of NO by 1. Here, since the maximum bank number is 16, it is supposed to return to 1 when the added value exceeds 16. In step 65, the display of the bank number in the lower part of the display 37 is rewritten with the new contents of BANKNO. When the data down switch DDW is turned on, steps 63a to 6 in FIG.
By 5a, processing is performed in substantially the same manner as steps 63 to 65 in FIG. The difference is that BANKN is used in step 64a.
It is to decrease the bank number of O by 1, and when the subtraction value is smaller than the minimum value 1, the value is returned to 16.

As described above, when the MMNO is "3", the desired bank number can be designated by operating the switches DUP and DDW, and this is stored in BANKNO. The bank number stored in this BANKNO designates a bank for exchanging information in bank units between the external memory and the internal memory in the normal mode.

<Normal Parameter Editing Function> When collectively transferring and writing the parameter data of the bank number designated by BANKNO from the external memory to the internal memory, the confirmation switch CFSW is pressed while pressing the from pack switch FPSW. When the desired bank number is set in the BANKNO register as described above, the value in the MMNO register is "3", and step 136 in the routine of FIG. 17 executed when the confirmation switch CFSW is turned on is YES. , Proceeds to step 137. At this time, from pack switch FPSW
Is turned on at the same time, step 137 is YES, and the routine proceeds to step 138.

At step 138, the contents of the pack code stored in PKCODED are examined, and step 1 is performed according to the contents.
Proceed to 39-141. In the case of only the registration data, the process proceeds to step 139, and the registration data bank P of the external memory corresponding to the bank number stored in BANKNO.
The registration data for one bank is read from ACKR (BANKNO), and the registration data RMEM of the RAM 29 is read.
(1) to write to the storage locations of RMEM (16). If the pack code indicates only the voice parameter, the process proceeds to step 140, and the voice parameter bank PACKV (BAN (BAN) of the external memory corresponding to the bank number of BANKO.
KNO) reads the voice parameters for one bank from the voice parameters TCPW (65)-
Write to the storage location of TCPW (72). Step 14 if the pack code shows both parameter information

Reads both registration data and voice parameters for one bank from PACKV (BANKNO)
AM29 RMEM (1) to RMEM (16), TCP
Write to W (65) to TCPW (72), respectively.

In step 142, the display 37 displays a predetermined display. First, the display "CO
"PY END" and then returns to the display of the bank number. The display on the upper row depends on the contents of the pack code.

When collectively copying the parameter information of the bank number designated by BANKNO from the internal memory to the external memory, press the confirmation switch while pressing the memory switch MSW. In this case, N in step 137 of FIG.
O, YES in step 143 to step 144
Proceed to. Here, it is checked whether the bank designated by BANKNO is bank protected. That is, the stored content of the bank protect memory BKPRO (BANKNO) corresponding to the bank number of BANKNO is read and it is checked whether it is "0" (whether rewriting is prohibited). If not prohibited, step 138a which is almost the same as steps 138 to 141 described above.
~ 141a are processed, and it progresses to Step 142. However, steps 139a to 141a are opposite to the case where the copy direction is steps 139 to 141.

<Selection of special parameter editing function> As a special parameter editing function, (1) partial copy,
(2) Bank protect, (3) Pack code write,
There are three types. Multi menu number register MMNO
Is "2", that is, when an external memory pack is inserted, the enter switch ETR is turned on to select the function.

When the enter switch ETR is turned on when MMNO = 2, the process proceeds from YES in step 66 of FIG. 15 to step 67, and the content of the MMNO register is set to "4". MMNO = 4 corresponds to the "partial copy" function. In the next step 68, the multi-menu display 37
"PACK EDIT" is displayed in the upper row, and "1. PARTIAL COPY" is displayed in the lower row to indicate that the "partial copy" parameter editing function is selected.
By operating the menu up switch MUP and the down switch MDW in this state, the contents of the MMNO register are cyclically changed to any one of "4", "5", and "6". MMNO = 5 corresponds to the "bank protect" function. When this is selected, the upper part of the display 37 is "PACK EDIT" and the lower part is "2. BANK."
"PROTECT" is displayed (for example, refer to the inside of the block of step 71 in FIG. 11).

MMNO = 6 corresponds to the "pack code write" function, and when this is selected, "P
ACK EDIT ”, the lower line“ 3. PACK COD
“E” is displayed (for example, refer to the inside of the block in step 74 of FIG. 11).

Steps 69 to 71, 72 to 74, 75 to 7 in FIG.
As is clear from 7, menu up switch MUP
Each time the is turned on, the contents of the MMNO register are "4" →
It repeatedly changes in the order of “5” → “6” → “4” → ..., It is possible to select one of the editing functions. Steps 69a to 77a in FIG. 12 correspond to steps 69 to 77 in FIG.
Although it corresponds to the processing of 77, the order is different as shown. Steps 69a and 73 of this FIG.
a, 74a, 72a, 76a, 77a, 75a, 70
As is clear from the processing of a and 71a, every time the menu down switch MDW is turned on, the content of the MMNO register changes in the order of “4” → “6” → “5” → “4” → ...
Either editing function can be selected.

<Partial Copy Mechanism> When the enter switch ETR is turned on when MMNO = 4, it is confirmed that the “partial copy” process is performed, and
From YES in step 78 to step 79 in the figure, M
The content of the MNO register is set to "7". This starts the "partial copy" process. External memory (PACKR (1) to PACKR (1
6), PACKV (1) to PACKV (16)) and internal memory (RMEM (1) to RMEM (16), TCPW (65) to TCP
W (72)), various registers, and the flow of main information between switches are schematically shown in FIG.

In the state of MMNO = 7, a process of selecting a bank number for partial copy is performed. In step 80 of FIG. 15, the content of the partial copy bank number register PCBKNO is set to the initial value "1". In the next step 81, the PCB
The bank number stored in the KNO is displayed in the lower part of the display 37, and "PARTIAL COPY" is displayed in the upper part. In the block of step 81, an example of the display contents on the display 37 is shown.

In the state of MMNO = 7, the data up switch DU
PBKNO by operation of P and down switch DDW
The value of is changed. When the switch DUP is turned on, the process proceeds from YES in step 82 to step 83 in FIG.
Then, the bank number of PCBKNO is incremented by 1. Here, since the maximum bank number is 16, it is assumed that when the added value exceeds 16, it returns to the minimum value 1. Step 84
Then, the bank number display in the lower part of the display 37 is rewritten with the new contents of PCBKNO. When the data down switch DDW is turned on, the steps 82a to 84a in FIG. 14 are followed by the step 8 in FIG.
The processing is performed in the same manner as 2 to 84. The difference is that the bank number of PCBKNO is decremented by 1 in step 83a. In this case, since the minimum bank number is 1, when the subtraction value is less than 1, it is returned to the maximum value 16.
In this way, select the bank number for partial copy, and
Store in BKNO register.

The method of circulating the maximum value or the minimum value when the value exceeds the minimum value or the maximum value when increasing or decreasing the value in the register is not limited to the above steps 83 and 83a, and is the same in other steps.

After selecting the bank number, enter switch ET
R is turned on and MMNO is switched to "8" (steps 85 and 86 in FIG. 15). In step 87, the contents of the partial copy designation registers CPREG and CPVIC are reset to "0". In the next step 88, the display 37 displays “PARTIAL COPY” “1. REGIST Y”.
/ N ”is displayed. This is an inquiry as to whether to make a partial copy of the resist data.

In response to the inquiry "Y / N", the player responds by turning on the data up switch DUP if YES and turning on the data down switch DDW if NO.

When the data up switch DUP is turned on when MMNO = 8, it means that partial copy of the resist data is selected, and YE in step 89 in FIG. 13 is selected.
The process proceeds from S to step 90, and the content of the register CPREG for instructing the partial copy of the resist data is set to "1". Next, in step 91, the content of the register MMNO is set to "9".

In the next step 92, "PARTIAL COPY"
The display 37 displays the inquiry “2. VOICE Y / N”. This asks if you want to do a partial copy on the voice parameters.

When the data up switch DUP is turned on when MMNO = 9, it means that the partial copy of the voice parameter is selected, and Y in step 93 of FIG. 13 is selected.
The process proceeds from ES to step 94, and the content of the register CPVIC instructing the partial copy of the voice parameter is set to "1". Next, MMNO is set to "10", copy direction register PKTOEL is set to "1", and display 37
In step 95-97, a display indicating that partial copying is performed from the external memory to the internal memory is performed.

Data down switch DD when MMNO = 8 or 9
When W is turned on, the processing of steps 89a to 97a in FIG. 14 corresponding to the processing of steps 89 to 97 in FIG. 13 is performed. However, in steps 90a and 94a, CP
“0” is set in REG or CPVIC, and it is stored that partial copy is not performed.

When MMNO is 10 or 11, the direction of partial copy can be switched by the menu up / down switches MUP and MDW. Steps 98 to 1 in FIG.
By the processing of 05, the copy direction is switched every time the menu up switch MUP is turned on. By the similar processing in FIG. 12, the copy direction is switched every time the menu down switch MDW is turned on. MMNO = 11
In this case, the PKTOEL register is set to "0", and the display 37 indicates that the partial copy is performed from the internal memory to the external memory (step 99-).
101).

When the enter switch ETR is turned on when the MMNO is "10" or "11", the MMNO is switched to "12" and the display for confirming the direction of the partial copy is displayed on the display 37 (step 106 to FIG. 15). 111). If the displayed direction is acceptable, turn on the data up switch DUP,
If it is not good, the data down switch DDW is turned on.

When the data up switch DUP is turned on when MMNO = 12, step 112 of FIG. 13 becomes YES, and step 113 checks whether the content of PKTOEL is "1". If YES, the process proceeds to step 114 to make a partial copy from the external memory to the internal memory. In step 114, it is checked whether CPREG is "1",
If YES, the process proceeds to step 115, and the PKCODE pack coat is "1" (only resist data) or "3".
(Both registration data and voice parameters). If the CPREG is "1", a partial copy of the resist data is requested, so that it is confirmed in step 115 whether the resist data is stored in the external memory. If YES in step 115, the process proceeds to step 116, and the partial copy bank number register PC
The resist data stored in one bank PACKR (PCBKNO) of the external memory corresponding to the bank number stored in BKNO is read out to store the registration data RMEM (1) to RMEM (16) in the RAM 29 (registration area). Data memory).

In step 117, it is checked whether CPVIC is “1”. If YES, the process proceeds to step 118, PKCODE
It is checked whether the pack code stored in "2" (only voice parameter) or "3" (both registration data and voice parameter). If the CPVIC is "1", a partial copy of the voice parameter is requested, so it is confirmed in step 118 whether the voice parameter is stored in the external memory. If YES at step 118, the process proceeds to step 119, at which the register PCB
The voice parameter stored in one bank PACKV (PCBKNO) of the external memory corresponding to the bank number stored in KNO is read out and the storage area (voice parameter of voice parameters TCPW (65) to TCPW (72) in RAM 29 is read. Write to memory).

In step 120, the display 37 indicates that the partial copy is completed.

If partial copy is to be performed from the internal memory to the external memory, step 113 is NO, and the routine proceeds to step 121. Here, it is checked whether the bank instructed to perform the partial copy is bank protected. PC
Bank protect memories BKPRO (1) to BKPRO (16) corresponding to the bank numbers stored in BKNO
To bank protect data BKPRO (PCBKN
O) is read and it is checked whether it is “0” (whether rewriting is prohibited). YES in step 121
In that case, steps 114a to 119a having substantially the same contents as those of steps 114 to 119 described above are executed, and step 12
It reaches 0. In steps 116a and 119a, writing is performed in the opposite direction to the above steps 116 and 119. That is, in step 116a, 16 sets of registration data R are registered from the registration data memory of the internal RAM 29.
The MEM (1) to RMEM (16) are read and written in the resist data bank PACKR (PCBKNO) designated by the PCBKNO of the external memory. At step 119a, eight sets of voice parameters TCPW (65) to TC are read from the voice parameter memory of the internal RAM 29.
Read PW (72). PCBKNO of external memory
Voice parameter bank PACKV indicated by
Write to (PCBKNO).

When the data down switch DDW is turned on when MMNO = 12, step 122 of FIG. 14 becomes YES and the routine proceeds to step 123. In step 123, the display 37 is caused to perform a predetermined display indicating that the partial copy is not executed.

<Bank protect function> When the enter switch ETR is turned on when MMNO = 5, it is confirmed that the “bank protect” process is performed.
YES from step 124 to step 125 in FIG.
Then, the contents of the MMNO register are set to "13". As a result, the "bank protect" process is started. The flow of main information in the "bank protect" process is schematically shown in FIG.

In the state of MMNO = 13, a process for selecting a bank number for bank protection is performed. In step 126 of FIG. 15, the protect bank number register PRBKNO
Is set to the initial value "1". Next step 127
Then, the bank number stored in PRBKNO is displayed on the display 37. An example of this display content is step 127.
Are shown in blocks. “B
“ANK PROTECT” is displayed, and the bank number is displayed in the lower row.

In the state of MMNO = 13, the data up switch DU
PRB by operating P, data down switch DDW
The value of KNO is changed. Data up switch DUP
When is turned on, YE of step 128 in FIG. 13 is performed.
After passing S, the processing of steps 129 and 130 is performed. This is similar to the processing of steps 83 and 84 described above,
The bank number of the register PRBKNO is incremented by 1 and displayed on the display 37. When the data down switch DDW is turned on, steps 128a to 13 in FIG.
0a performs the same processing as steps 128 to 130 in FIG. However, in step 129a, PRBKNO
Decrease the bank number of 1.

After selecting the bank number, enter switch ET
Turn R on and switch MMNO to "14" (15th
Steps 131 and 132 in the figure). In step 133,
On the display 37, the bank number for bank protection (that is, the bank number stored in PRBKNO)
Is displayed and asks whether to perform bank protect.

When the data up switch DUP is turned on when MMNO = 14, it means that bank protection is selected for the bank number stored in PRBKNO, and the process proceeds from YES in step 134 to step 135 in FIG. Bank protection memories BKPRO (1) to BKPRO (16) in the external memory (6th
The signal "1" is written in the one corresponding to the bank number of the register PRBKNO (shown by BKPRO (PRBKNO)) in the figure). In this way, it is stored that bank protection (rewriting prohibition) should be performed for the specified bank number. On the contrary, the data down switch DD
When W is turned on, steps 134a and 13 in FIG.
By the processing of 5a, the storage content of the designated bank protect memory BKPRO (PRBKNO) in the external memory is reset to "0". In this way, the bank protection (prohibition of rewriting) is canceled for the designated bank number.

When a batch copy or partial copy is to be executed for a bank protected bank, step 121 in FIG. 13 is NO in the case of partial copy, and step 144 in FIG. 17 is NO in the case of batch copy. Therefore, it is prohibited to proceed to the rewriting process. In this way, rewriting is prohibited. If NO in step 121, the process proceeds to step 146, in which a predetermined display "PARTIAL COPY" indicating partial copy, a display "BANK X" indicating a bank number, and a display "P" indicating that rewriting is prohibited.
"ROTECT" is displayed on the display 37.
When step 144 is NO, the routine proceeds to step 145,
The display 37 displays a display "FROM EL TO PACK" indicating copying from the electronic musical instrument body to the external memory, a display "BANK X" indicating a bank number, and a display "PROTECT" indicating prohibition of rewriting.

<Pack Code Writing Function> When the enter switch ETR is turned on when MMNO = 6, it is determined that the "pack code writing" process is performed, and YES to step 1 in step 147 of FIG.
Proceeding to 48, the contents of the MMNO register are set to "15". As a result, the "pack code write" process is started.

In step 149, the content of the pack code buffer PKCBF is set to the initial value "3". Pack code "3"
Is identification data indicating that both the registration data and the voice parameter are stored in the external memory, and this is the initial value. However, the pack code currently stored in PKCODE on the external memory side may be set as the initial value in PKCBF instead of setting “3” as the initial value.

In step 150, "PACK CODE EDIT" is displayed on the upper stage of the multi-menu display 37, and P is displayed on the lower stage.
Identification information corresponding to the back code stored in the KCBF, for example, in the case of the pack code “3”, “REGIST
& VOICE ”is displayed. In this state, the menu up switch MUP and the menu down switch MD
By operating W, the pack code of PKCBF can be changed.

Steps 151-154, 155-178 of FIG.
As is clear from the processing of 159 to 162, the contents of the MMNO register are "15" → "16" → "17" → "15" → every time the menu up switch MUP is turned on.
It changes cyclically in the order of…, and the pack code of PKCBF is “3” (indicating resist and voice) with this →
It changes cyclically in the order of "1" (indicating only resist → "2" (indicating only voice) → "3" → ..., and any pack code can be selected. An identification display showing the contents of the pack code is displayed on the display 37 (steps 154, 158, 162).

When the menu down switch MDW is turned on, the first
Steps 151a, 156a to 158a, 155 of FIG.
a, 160a to 162a, 159a, 152a to 154
The process a is executed. In this case, every time the menu down switch MDW is turned on, the contents of the MMNO register cyclically change in the order of “15” → “17” → “16” → “15” → ..., and the pack code of PKCBF is accordingly changed. Changes cyclically in the order of “3” → “2” → “1” → “3” → ..., and any pack code can be selected.

When writing the pack code stored in the pack code buffer PKCBF to the pack code memory PKCODE of the external memory, the enter switch ETR is turned on.
The contents of the MMNO register are "15", "16", "1".
When the enter switch ETR is turned on at any time of "7", the contents of the MMNO register are changed to "18" and P
The contents of the pack code stored in the KCBF are displayed on the display 37, and it is inquired whether this is enough (15th).
Steps 163-171 in the figure). If that is all right, the data up switch DUP is turned on. Then, thirteenth
After confirming that MMNO = 18 in step 172, the process proceeds to step 173, and the pack code of PKCBF is written in the pack code memory PKCODE of the external memory. In the next step 174, a predetermined end display is displayed on the display 37. If it is not desired to write the pack code displayed at step 171 (FIG. 15), the data down switch DDW is turned on. Then, in step 175 of FIG. 14, it is confirmed that MMNO = 18, the process proceeds to step 176, the display indicating that the pack code is not written is displayed on the display 37, and the process is ended.

<Other Embodiments> FIG. 22 shows an embodiment in which a rhythm selection switch is used instead of the above-mentioned multi-menu switch section as means for selecting a tone color to be assigned to a white switch. Blocks with the same reference numerals as in FIG. 2 are the same or corresponding devices.

The arrangement of the tone color switches in the tone color switch section 22 is the third.
Assuming the same as in the figure, TCSW1 to TCSW6 fixedly correspond to predetermined timbres, and TCSW7 and TCS
Suppose W8 is a white switch.

FIG. 23 shows an example of a switch arrangement in the rhythm selection switch section 178. A plurality of (eight in the figure) rhythm selection switches RHSW1 to RHSW8 are provided corresponding to the rhythm name, and a character display 179 indicating the rhythm name corresponding to each switch and an LED 18 corresponding to each of them are provided above the rhythm selection switches RHSW1 to RHSW8.
1 is provided. Also, on the lower side of each switch R
A character display 180 indicating a tone color name for white switch assignment that can be selected by HSW1 to RHSW8 is attached. In this case, the rhythm selection switches RHSW1 to RH
The SW8 has two functions, an original rhythm selection function and a function to select a tone color to be assigned to the white switch. When the rhythm selection switches RHSW1 to RHSW8 work with the rhythm selection function (this is referred to as a rhythm selection mode), the LED 182 attached with the display "AUTO RHYTHM" lights up. In this state, when the desired switches RHSW1 to RHSW8 are pressed, the LED 181 corresponding thereto is turned on, and the rhythm corresponding thereto is selected. On the other hand, rhythm selection switches RHSW1 to RHS
When the W8 works with the tone color selection function (this is called the voice menu mode), "VOICE MENU"
The LED 183 attached with the display is turned on. In this state, when the desired switch RHSW1 to RHSW8 is pressed, the LED 180 corresponding to the switch is turned on, and the timbre corresponding to the timbre name displayed correspondingly is selected.

Normally, the LED 182 is on and the switch unit 17
8 works in rhythm selection mode. Tone color switch section 22
When the white switch TCSW7 or TCSW8 is pressed in, the LED 182 is turned off and the LED 183 is turned on to enter the voice menu mode. When a desired switch RHSW1 to RHSW8 is pressed in this state, the tone color corresponding to the pressed switch is the pressed white switch TC.
It is assigned to SW7 or TCSW8.

This point will be described in more detail.

FIG. 24 shows an example of a memory map in the parameter ROM 30 of FIG. 22, in which the tone color parameters TCP (1) to TCP (6) corresponding to the tone color switches TCSW1 to TCSW6 one to one are described. ) And 8 corresponding to the rhythm selection switches RHSW1 to RHSW8
Tone parameters TCPWH (1) to TCPW of various tones
H (8) is stored.

FIG. 25 shows the data and working RA in FIG.
It is a memory map of M29. There, TCSW
Is a register for storing the number of the tone color switch which is detected to be turned on based on the scanning result of the tone color switches TCSW1 to TCSW8, as described above. TCSWOF
Is a register for storing the number of the tone color switch that has changed from ON to OFF based on the scanning result.

WHEVT is a white switch event register, and a signal "1" is set when any of the white switches is turned on, and it is a mode (voice menu mode) in which a desired timbre can be assigned to the white switch. Show.

The WHTC (7) and WHTC (8) store the tone color code of the tone color currently assigned to each white switch, as described above.

RHSW is a rhythm selection switch RHSW1 which is turned on.
~ The number of RHSW8 is stored.

As in the embodiment shown in FIG. 2, in the embodiment shown in FIG. 22, the switch scanning process and other processes are executed by the microcomputer. Tone color switches TCSW1 to TCSW
When it is detected that any one of 8 is turned on, a tone color switch-on event routine as shown in FIG. 26 is executed. When it is detected that any of the rhythm selection switches RHSW1 to RHSW8 is turned on, a rhythm switch on event routine as shown in FIG. 27 is executed. When any of the tone color switches TCSW1 to TCSW8 changes from on to off, a tone color switch off event routine as shown in FIG. 28 is executed.

In FIG. 26, the number of the tone color switch that has been turned on is stored in the register TCSW (step 184), and the corresponding LED is turned on (step 18).
5). In step 186, similarly to step 38 in FIG. 8, it is checked whether the tone color switch which is turned on is the white switch. If the white switch is turned on, "1" is set in the register WHEVT (step 18).
7), auto rhythm LE of the rhythm selection switch section 178
The D182 is turned off and the voice menu LED 183 is turned on (step 188). Then, the tone color code currently assigned to the turned-on white switch is registered in the register WHTC (7) or WHTC (8) (this is WHTC
(Indicated by (TCSW)), and the tone color parameters (TCPWH (1) to TCPW) corresponding to this tone color code are read.
H (8)) is read from the parameter ROM 30 and this parameter is supplied to the tone generation circuit 34.

On the other hand, if the turned-on tone switch is not the white switch, the contents of the register WHEVT are reset to "0" (step 190), and the voice menu LED 183 is set.
Is turned off and the autorhythm LED 182 is turned on (step 191). Then, the tone color parameter TCP (TCSW) corresponding to the tone color switch turned on is set to the parameter RO.
It is read from M30 and supplied to the tone generation circuit 34 (step 192).

In FIG. 27, first, the number of the rhythm selection switch turned on is stored in the register RHSW (step 1
93) and the corresponding LED 181 is turned on (step 194). In step 195, WHEVT
Check whether the content of is "1". If "1", R
The number stored in the HSW (this corresponds to a tone color code for identifying eight tone colors) is registered in the register WHTC (TCSW) corresponding to the turned-on white switch (step 196). Next, a tone color parameter TCPWH (RHSW) corresponding to the tone color code just registered.
(Any of TCPWH (1) to TCPWH (RHSW)) is read from the parameter ROM 30 and supplied to the musical tone generating circuit 34 (step 197).

On the other hand, if WHEVT is "0", the process proceeds to step 198, and the number stored in RHSW (this corresponds to the rhythm code) is supplied to the rhythm tone generator in the tone generation circuit 34. In the rhythm selection mode, not only the rhythm corresponding to the switches RHSW1 to RHSW8 on a one-to-one basis but also another rhythm can be selected by pressing two adjacent switches at the same time. The description of the processing routine for detecting the simultaneous pressing of the adjacent rhythm selection switches in different rhythm selection modes is omitted.

In FIG. 28, first, the number of the tone color switch that has been turned off is stored in the register TCSWOF (step 19).
9) Next, it is checked whether this tone color switch is a white switch (step 200). If it is a white switch, it is checked whether or not this turned off white switch (content of register TCSWOF) is the same as the tone color switch (content of TCSW) turned on last (step 201). If two or more timbre switches are turned on at the same time, step 201 is NO if the white switch that has been turned off is not the one that was turned on last.
And return. If the white switch that has been turned off is the tone switch that was turned on last, that is, if the white switch is currently set to the voice menu mode, the process proceeds to step 202,
The contents of the register WHEVT are reset to "0". In the next step 203, the LED 183 of the rhythm selection switch section 178 is turned off and the LED 182 is turned on as in step 191 of FIG.

As is clear from the above, it is possible to assign a desired tone color to the white switch in the embodiment of FIG.
When the white switch is operated, the parameter information corresponding to the tone color assigned to the white switch is supplied to the tone generating circuit and the assigned contents are automatically set to a mode in which the parameter can be changed.

<Modification> In the above-described embodiment, the parameter information for setting the characteristic of the musical tone is the parameter information related to the tone color setting, that is, the voice parameter and the preset (registration) data, but the present invention does not use any other parameter information. It can also be applied when handling. That is,
The parameter information for the musical tone characteristic setting referred to in the present invention is
It contains all the information that is related to the setting of the musical tone characteristics in some way, let alone the information related to the tone color setting.
Information related to setting, selection, and control of volume, pitch, effect, automatic performance, rhythm performance, and other musical tone control functions. Therefore, handling of information for setting the generation pattern of an automatic arpeggio sound or an automatic rhythm sound is also included in the scope of the present invention.

Of course, the program flow of each processing routine is not limited to that shown in the drawing.

Further, in the above embodiment, the number of white switches (switches to which parameter information can be assigned) is 2, but this may be 1 or 2 or more.

In addition, the tone color switch section as shown in FIG. 3 (that is, one having a plurality of white color switches and a plurality of tone color switches corresponding to a fixed tone color) is provided for each of a plurality of different tone groups. You may In that case,
The memory storing the parameter information to be assigned to the white switch may be shared by each sound group.

In the embodiment of FIG. 2, the voice parameter created by the performer or the voice parameter imported from the external memory can be assigned to the white switch. However, this is not essential, and the voice parameter set in the ROM or RAM is assigned. Only the parameters may be targeted.

In the embodiment, the tone color code of the tone color assigned to the white switch is stored in the register corresponding to the white switch,
The voice parameter corresponding to this tone color code is read out from the memory storing the voice parameter corresponding to each assignable tone color, but not limited to this, the tone color assigned to the white switch in the register corresponding to the white switch. The voice parameters may be directly stored.

In the embodiment of FIG. 22, the rhythm selection switch is used instead of the multi-menu switch section to select the white switch assigning tone color, but other operators on the panel section (for example, effect switch and automatic accompaniment). switch)
May be used.
