Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention stores parameter information related to settings of various musical tone characteristics such as timbre, volume, pitch, and effects in a storage device, and The present invention relates to a parameter editing device that can partially inhibit rewriting of parameter information in a storage device in an electronic musical instrument in which parameter information stored in the device is read out and used for setting musical tone characteristics.

[Conventional technology]

Generally, electronic musical instruments are equipped with a large number of manual controls for selecting various tones, volumes, effects, etc. on/off or in step-by-step settings, and the outputs of these controls are used in musical tone forming circuits. That's what I do. In this case, when a certain controller is operated, parameter information (for example, voice parameters) that sets the musical tone characteristics assigned to that operator is given to the musical tone forming circuit, and the musical tone is created based on this parameter information. Characteristics are set. On the other hand, parameter information corresponding to the desired setting state of each controller is stored as a set of preset data, and by operating a switch, the set of preset data can be read out all at once and used to set musical tone characteristics. Electronic musical instruments have also been known that have a preset function for use. Individual parameter information and preset data corresponding to each controller are generally stored in an electronic storage device inside an electronic musical instrument, and are selectively retrieved from this storage device to set and control musical tones. used for. In this case, the capacity of the internal storage device is naturally limited, so in order to make a large amount of parameter information and preset data available, an external storage medium (such as a magnetic card, non-volatile memory, battery-backed semiconductor device, etc.) is required. Various parameter information and preset data are stored in a memory (such as a memory), a desired external storage medium is attached to the electronic musical instrument, and data is transferred from the storage medium to the internal storage device. The parameter information (including preset data) stored in the internal storage device is rewritten (set) as appropriate according to the operation of the predetermined controls.

RMEM16 is stored. The main registers TCSW to PKCBF in the RAM 29 will be explained next.

TCSW is a register that stores the scanning results of tone switches TCSW1 to TCSW8.

WHTC7 is one white switch TCSW
This register stores the timbre code of the timbre currently assigned to timbre 7.

WHTC8 is the other white switch
This register stores the tone code of the tone currently assigned to TCSW8.

TCCODE is a register that stores the timbre code of the timbre name currently displayed on the multi-menu display 37 (FIG. 3).

MMNO is a register that stores a multi-menu number indicating the function currently being processed using the multi-menu switch unit 23.

BANKNO is a register that stores a bank number that designates a bank in which parameter information should be exchanged between the external memory 31 and the internal memory (RAM 29). As will be described later, the external memory 31 stores parameter information in a plurality of banks, and exchanges information with each bank as one unit.

PCBKNO is a register that stores a bank number that specifies the bank to which a partial copy is to be performed. As will be described later, one bank is composed of a plurality of different types of parameter information, that is, voice parameters and registration data. The process of transferring parameter information in one bank between an external memory and an internal memory not all at once but partially (by selecting a specific type) and writing it to the other party is called "partial copy."

PRBKNO is a register that stores a bank number that specifies a bank to which bank protection (rewriting prohibited in bank units) control is to be performed.

PKTOEL is a register that stores data indicating the copy direction when performing partial copy.
When writing from external memory to internal memory
PKTOEL (Pack to Electone) is "1", and conversely, when writing from internal memory to external memory, PKTOEL is "0".

CPREG and CPVIC are registers that store data that independently designates each type of parameter information to be partially copied. CPREG
stores "1" when partially copying the registration data (preset data), and stores "0" when not copying. CPVIC stores "1" when a voice parameter is partially copied, and stores "0" when not to copy.

REGNO is a register that stores the number of the selected registration switch REGSW (FIG. 3).

PKCBF is a pack code buffer register and stores data (pack code) that identifies the type of parameter information stored in the external memory 31.

In addition to the above-mentioned resists, the RAM 29 also has a data memory area for storing key switch scan results, key information assignment data for each channel, and scan data for other various switches and controls on the panel section 21. Contains the working memory area.

FIG. 6 shows a memory map of the external memory 31, and the pack code memory PKCODE and the bank protect memories BKPRO1 to BKPRO16 are read and written in principle in bank units (however, in the case of partial copying, only a part of the bank can be selectively read/written). It consists of a parameter memory section 310 (which can be read and written to).

The parameter memory section 310 stores one or more types of parameter information for each of 16 banks. In this embodiment, the types of parameter information are registration data and voice parameters,
PACKR1 to PACKR16 are register data banks, and PACKV1 to PACKV16 are voice parameter banks. Numbers 1 to 16 in parentheses indicate bank numbers. Registry data bank PACKR1~
PACKR16 has 16 sets of registration data per bank (this is RMEM stored in the registration data memory of internal RAM 29 in FIG. 5).
1 to RMEM16) are stored respectively. Voice parameter bank PACKV1~
PACKV16 has 8 sets of voice parameters per bank (TCPW65 to 8 stored in the voice parameter memory of internal RAM 29 in FIG. 5).
corresponding to TCPW72).

Depending on the type of external memory 31, the parameter memory section 310 may store a registration data bank.
It includes one or both of PACKR1 to PACKR16 and voice parameter banks PACKV1 to PACKV16. Normally, even if the types of parameters are different, if they have the same bank number, they are grouped together as data in the same bank and read/write is controlled. For example, when reading the parameters of bank number 1, use bank PACKR1.
The registration data and voice parameters of PACKV1 are read. However, in the case of partial copy control, read/write control is performed independently for each type of parameter within the same bank.

The pack code memory PKCODE stores identification data (pack code) for identifying this external memory 31 by the type of parameter information stored therein. For example, it consists of data identifying only registration data (pack code "1"), only voice parameters (pack code "2"), or both registration data and voice parameters (pack code "3").

Bank protect memory BKPRO1 to BKPRO
Reference numeral 16 stores data specifying whether or not to prohibit rewriting of the stored data corresponding to each bank.Banks in which rewriting is prohibited store a signal "1", and banks in which rewriting is not prohibited store a signal "0". Remember.

<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 tone switch section 22
A scanning process S1 is performed. Here, when an on event of any of the tone color switches TCSW1 to TCSW8 is detected, the tone color switch on event subroutine of FIG. 8 is executed.

Next, a process S2 is performed to detect that the external memory 31 is inserted into the interface 32. Here, when it is detected that the external memory has been inserted, the pack insertion event subroutine shown in FIG. 9 is executed.

Next, a scanning process S3 of the multi-menu switch section 23 is performed. Here, when the on event of the menu switch MUP is detected,
When the subroutine in Fig. 11 is executed and an on event of the menu down switch MDW is detected, the subroutine of Fig. 12 is executed, and when an on event of the data up switch DUP is detected, the subroutine of Fig. 13 is executed. 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. 15 is executed.

Next, a scanning process S4 of the registration switch unit 24 is performed. Here, when an on event of any of the registration switches REGSW is detected, the subroutine shown in FIG. 10 is executed. Further, when an on event of the from pack switch FPSW is detected, the subroutine of FIG. 16 is executed, and when an on event of the confirmation switch CFSW is detected, the subroutine of FIG. 17 is executed.

Next, a scanning process is performed on other operator sections 25 related to the multi-menu, and further a scanning process is performed on other operator sections 26. Next, processing related to the voice parameter creation device 33 is performed. In this process, the voice parameters created according to the performer's preferences are stored in the RAM 29.
Written as TCPW65 to TCPW72.
Finally, the key switch circuit 20 is scanned, and based on the scan results, sound generation is assigned to each channel.

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

First, turn on the tone switch (TCSW1~
8) in the TCSW register, and then store the number corresponding to the tone switch that was turned on.
Turn on the LED. Next, it is checked whether the number stored in TCSW is 7 or more (step 38). 7
If it is above, white switch TCSW7 or
This means that TCSW8 has been turned on, and if it is less than 7, the normal tone switches TCSW1 to TCSW6 have been turned on.

If the white switch has been turned on, the process advances to step 39, and the multi-menu number of register MMNO is set to "1". In step 40, the white switch assigned tone code register WHTC7 or WHTC8 (which corresponds to switch number 7 or 8 stored in register TCSW) is
The tone code stored in the WHTC (indicated by TCSW) is read out and given to the multi-menu display tone code register TCCODE. In 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, display 3
The display contents of step 7 are as illustrated in the block of step 41. In this display, "VOICE MENU" at the top is the multi-menu number.
This is the menu display corresponding to MMNO=“1”,
This indicates a mode in which the multi-menu switch unit 23 functions as a means for selecting a tone color to be assigned to the white switch. The display at the bottom shows the tone name corresponding to the tone code of TCCODE. In the example shown, the tone code is "01" and the corresponding tone name is "STRINGS1".
It is. Therefore, the display in the lower row changes depending on the contents of TCCODE. Through this process, the timbre name of the timbre currently assigned to the turned-on white switch TCSW7 or TCSW8 is displayed on the multi-menu display 37. In step 42,
The voice parameter (one of TCPW1 to TCPW72, indicated by TCPW (TCCODE)) corresponding to the tone code of TCCODE is set internally.
The data is read from the RAM 29 or ROM 30 and supplied to the musical tone generation circuit 34 (indicated by TG). As a result, the tone of the musical tone signal generated by the musical tone generating circuit 34 is set in accordance with the voice parameter assigned to the white switch that has been turned on.

If the turned-on timbre switch is not a white switch, the process advances from NO in step 38 to step 43, where the contents of the register MMNO are reset to "0". In the next step 44, the voice parameter (TCP 1 to 6) corresponding to the on switch number (any one of 1 to 6) stored in the TCSW is
Any one of TCP6, and this is TCP
(denoted as TCSW)) is read from the ROM30,
This is supplied to the musical tone generation circuit 34.

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

The registration switch on event routine shown in FIG. 10 will be explained.

First, turn on the registration switch.
Store the number of REGSW in register REGNO (step 48). Next, in step 49, it is checked whether the memory switch MSM is being turned on. If YES, proceed to step 50 and write one set of registration data.
If NO, the process advances to steps 51 and 52, and a set of registration data is read out. step
50, a set of registration data (any one of RMEM1 to RMEM16,
Numbers 1 to 16 are specified by REGNO, so they are indicated by RMEM (REGNO))
It is written to the registration data memory of RAM 29 as follows.

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 corresponding to the number of the turned-on registration switch stored in the register REGNO is
(REGNO) is read from the RAM 29, and the display of the setting status of a predetermined switch or operator on the panel section 21 is controlled according to the content of this registration data, and the setting content of the registration data is clearly shown to the performer. In step 53, parameter information corresponding to the read registration data RMEM (REGNO) is supplied to the tone generating circuit 34. thus,
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 explained below by function.

<Tone assignment function to white switch> When white switch TCSW7 or 8 is turned on, the process of step 39 (Fig. 8) described above will be performed.
The multi-menu number MMNO becomes "1". In this state, the mode is set in which the voice parameters of the tone assigned to the white switch are supplied to the musical tone generation circuit 34 to set the tone of the musical tone signal generated therein, and a different tone is newly assigned to the white switch. mode automatically.
The main flow of information at this time is shown in FIG.

As already explained in steps 38 to 42 of FIG. 8, when white switch TCSW7 or 8 is turned on, the tone code currently assigned to it is read from the corresponding white switch tone code register WHTC7 or WHTC8. and this is the multi-menu tone code register TCCODE
Stored in One set of voice parameters TCPW1~ according to the tone code of TCCODE
The TCPW 72 is read out and supplied to the tone generation circuit 34, and the name of the tone is displayed on the multi-menu display 37. This is the flow of reading voice parameters.

In mono mode, menu up switch
By changing the contents of TCCODE according to the operation of MUP or menu down switch MDW,
Select the desired tone from among the 72 tones corresponding to the voice parameters TCPW1 to TCPW72 (the selected tone name is displayed on the display 37), and at the same time store the memory in register WHTC7 or 8.
By rewriting the contents of TCCODE, the tone assigned to the white switch can be changed.

To explain the flow in this allocation mode,
When the menu switch MUP is turned on, in the routine shown in FIG.
Pass YES (MMNO=1) and step 55
Increase the tone code value of TCCODE by 1. In addition,
Since the maximum value is 72, when the added value exceeds 72, it returns to the minimum value 1. In the next step 56, the tone code of TCCODE is set to the register WHTC (TCSW) corresponding to the turned on white switch.
Register (assign) to. In the next step 54,
The voice parameter TCPW (TCCODE) corresponding to the tone color code of TCCODE is read out from the voice parameters TCPW1 to TCPW72, and the tone name thereof is displayed on the display 37. At step 58, the voice parameter TCPW (TCCODE) is supplied to the tone generating 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
Decrease the value of the TCCODE tone code by 1. In addition,
Since the minimum value is 1, when the subtracted value falls below 1, it returns to the maximum value 72.

<Function when external memory pack is inserted> When an external memory pack is inserted, MMNO becomes "2" by the process of step 45 (FIG. 9) described above. It has already been explained that at this time, information 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 multi-menu switch section 2
3 to specify a desired bank number. The bank number is specified by operating the data up switch DUP or the data down switch DDW.

Frompack switch when MMNO=2
When the FPSW is turned on, step 59 in Figure 16 is executed.
YES, and MMNO is set to "3" at step 60. In the next step 61, the bank number register BANKNO is set to "1" as an initial value. In the next step 62, the identification information corresponding to the pack code stored in PKCODE is displayed on the upper part of the display 37, and the bank number stored in BANKNO is displayed on the lower part of the display 37. An example of the display contents of the display 37 is shown in the block of step 62. Note that the symbol 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 or an appropriate character according to the contents of the pack code register.

When the confirmation switch CFSW is turned on when MMNO=2, steps 59a to 62a in FIG.
The process is similar to steps 59 to 62 in FIG. 16.

Note that even if MMNO = 2, if the mode is other than parameter editing (when the MMNO value is 19 or more, the multi-menu is being used for purposes other than parameter editing), steps 177 and 177a (first
Through the YES route in Figures 6 and 17)
MMNO=3 is set.

In the state of MMNO=3, switch DUP,
BANKNO value is changed by DDW operation. When the data up switch DUP is turned on, the process advances from YES in step 63 in FIG. 13 to step 64, where the bank number of BANKNO is incremented by one. Here, since the maximum bank number is 16, it is assumed that when the added value exceeds 16, it returns to 1. In step 65, the bank number display in the lower row of the display 37 is rewritten with the new BANKNO content. When the data down switch DDW is turned on, steps 63a to 63a in FIG.
65a, the processing is almost the same as steps 63 to 65 in FIG. The difference is that in step 64a
It is assumed that the bank number of BANKNO is decreased by 1, and if the subtracted value is less than the minimum value 1, it is returned to 16.

As described above, when MMNO is "3", the desired bank number can be specified by operating the switches DUP and DDW, and this
Stored in BANKNO. The bank number stored in BANKNO specifies the bank in which information is exchanged between the external memory and internal memory in bank units in normal mode.

<Normal parameter editing function> To transfer and write the parameter data of the bank number specified by BANKNO from the external memory to the internal memory all at once, press the confirmation switch CFSW while pressing the from pack switch FPSW. When the desired bank number is set in the BANKNO register as described above, the value of 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. , proceed to step 137.
At this time, if the from pack switch FPSW is turned on at the same time, step 137 is YES, and the process advances to step 138.

In step 138, the contents of the pack code stored in PACODE are checked, and the process proceeds to steps 139 to 141 depending on the contents. If only the register data is available, proceed to step 139, read one bank of register data from the register data bank PACKR (BANKNO) in the external memory corresponding to the bank number stored in BANKNO, and read the register data RMEM1 to RMEM16 in RAM29. Write to memory location. If the pack code indicates voice parameters only, proceed to step 140;
Voice parameter bank PACKV (BANKNO) in external memory corresponding to the bank number of BANKO
Read voice parameters for one bank from
RAM29 voice parameter TCPW65~
Write to storage location of TCPW72. If the PACK code indicates both parameter information, proceed to step 141 and store the PACKR in external memory.
(BANKNO), reads both the register data and voice parameters for one bank from PACKV (BANKNO), and reads RMEM1 to RMEM1 of internal RAM29.
Write to RMEM16 and TCPW65 to TCPW72, respectively.

In step 142, a predetermined display is made on the display 37. First, "COPY END" is displayed to indicate that the batch copy has been completed, and then the display returns to the bank number. The display in the upper row corresponds to the contents of the pack code.

To copy the parameter information of the bank number specified by BANKNO from the internal memory to the external memory all at once, press the confirmation switch while holding down the memory switch MSW. In this case, the first
The process proceeds to step 144 via NO at step 137 and YES at step 143 in FIG. here,
Check whether the bank specified by BANKNO is bank protected. In other words,
Read the memory contents of the bank protect memory BKPRO (BANKNO) corresponding to the bank number of BANKNO, and check whether it is "0" (whether rewriting is prohibited). If it is not prohibited, steps 138a to 141a, which are substantially the same as steps 138 to 141 described above, are performed, and the process proceeds to step 142. However, in steps 139a-141a, the copy direction is opposite to that in steps 139-141.

<Selection of special parameter editing functions> There are three types of special parameter editing functions: 1 partial copy, 2 bank protection, and 3 pack code writing. When the content of the multi-menu number register MMNO is "2", that is, when an external memory pack is inserted, the enter switch is pressed.
By turning on ETR, the mode is set to select these functions.

When the enter switch ETR is turned on when MMNO=2, the process advances from YES in step 66 in FIG. 15 to step 67, where the contents of the MMNO register are set to "4". MMNO=4 corresponds to the "partial copy" function. In the next step 68, the upper row of the multi-menu display 37 displays "PACK".
"EDIT" is displayed, and "1・PARTIAL" is displayed at the bottom.
COPY" is displayed to indicate that the "partial copy" parameter editing function has been selected. In this state,
By operating the menu up switch MUP and the down switch MDW, the contents of the MMNO register are cycled and changed to one of "4", "5", and "6".

MMNO=5 corresponds to the "bank protect" function, and when this is selected, the display 37
"PACK EDIT" in the upper row, "2・BANK" in the lower row
PROTECT" is displayed (for example, see the block at step 71 in FIG. 11).

MMNO=6 corresponds to the "pack code write" function, and when this is selected, display 3
"PACK EDIT" on the upper row of 7, "3・
"PACK CODE" is displayed (for example, see block 74 in FIG. 11).

As is clear from steps 69-71, 72-74, and 75-77 in FIG.
Every time the MUP is turned on, the contents of the MMNO register change repeatedly in the order of "4" → "5" → "6" → "4" →..., and one of the editing functions can be selected. The steps 69a-77a in FIG. 12 correspond to the steps 69-77 in FIG. 11, but the order is different as shown. Steps 69a, 73a, 74a, 72a, 76a,
As is clear from the processing of 77a, 75a, 70a, and 71a, each time the menu down switch MDW is turned on,
The contents of the MMNO register are "4" → "6" →
It changes in the order of "5" → "4" →..., and one of the editing functions can be selected.

<Partial copy function> When the enter switch ETR is turned on when MMNO=4, it is confirmed that the "partial copy" process will be performed, and the process proceeds from YES in step 78 in FIG. 15 to step 79, and the contents of the MMNO register become "7. ”
is set to This starts the "partial copy" process. External memory in “partial copy” processing (PACKR1 to PACKR16, PACKV1 to
PACKV16) and internal memory (RMEM1~
RMEM 16, TCPW 65 to TCPW 72), various registers, and switches, as shown in FIG. 20.

In the state of MMNO=7, processing for selecting a bank number for partial copying is performed. In step 80 of Figure 15, the partial copy bank number register is
Set the contents of PCBKNO to the initial value "1". In the next step 81, the bank number stored in PCBKNO is displayed on the lower row of the display 37, and "PARTIAL COPY" is displayed on the upper row. An example of the display contents on the display 37 is shown in the block of step 81.

In the state of MMNO=7, by operating the data up switch DUP and down switch DDW.
The value of PCBKNO is changed. When the switch DUP is turned on, select YES in step 82 in Figure 13.
Proceed to step 83 and increment the bank number of PCBKNO by 1. Here, since the maximum bank number is 16, when the added value exceeds 16, it returns to the minimum value 1. In step 84, the bank number display in the lower row of the display 37 is rewritten with the new contents of PCBKNO. data down switch
When the DDW is turned on, steps 82a to 84a in FIG. 14 lead to steps 82 to 84a in FIG.
Processed almost the same as 84. The difference is the steps
83a is to decrease the bank number of PCBKNO by 1. In this case, since the minimum bank number is 1, when the subtracted value falls below 1, it returns to the maximum value 16. In this way, the bank number for partial copying is selected and stored in the PCBKNO register.

Note that the method of circulating to the maximum or minimum value when the minimum or maximum value is exceeded when the numerical value in the register increases or decreases is not limited to steps 83 and 83a, but is the same in other steps as well.

When the selection of the bank number is completed, the enter switch ETR is turned on and the MMNO is switched to "8" (steps 85 and 86 in FIG. 15). In step 87, the contents of partial copy designation registers CPREG and CPVIC are reset to "0". In the next step 88, the display 37 shows "PARTIAL COPY" and "1.
REGIST Y/N” is displayed. This inquires whether to perform partial copying of the registration data.

In response to “Y/N”’s question, the performer said,
If YES, turn on the data up switch DUP,
If NO, turn on the data down switch DDW and respond.

Set the contents of the register CPVIC, which instructs partial copying of voice parameters, to "1". Next, set MMNO to "10" and copy direction register PKTOEL.
is set to "1", and the display 37 displays a message indicating that a partial copy is to be performed from the external memory to the internal memory (steps 95 to 97).

When the data down switch DDW is turned on when MMNO=8 or 9, the steps in Fig. 13 are executed.
Step 89a in FIG. 14 corresponding to steps 89-97
~97a processing is performed. However, step 90a,
In 94a, set CPREG or CPVIC to “0”,
Remember not to perform partial copy.

When MMNO is 10 or 11, menu up/
The direction of partial copying can be switched using the down switches MUP and MDW. Through the processing of steps 98 to 105 in FIG. 11, the copy direction is switched each time the menu switch MUP is turned on. By similar processing in FIG. 12,
The copy direction changes each time you turn on the menu down switch MDW. When MMNO=11
The PKTOEL register is set to "0", and a message indicating that a partial copy is to be performed from the internal memory to the external memory is displayed on the display 37 (steps 99 to 101).

When the enter switch ETR is turned on when the MMNO is "10" or "11", the MMNO is switched to "12" and a display confirming the direction of partial copying is made on the display 37 (steps 106 to 15 in FIG. 15).

Data up switch when MMNO=12
When DUP is turned on, step 112 in Figure 13
YES, and in step 113 it is checked whether the content of PKTOEL is "1". If YES, proceed to step 114 to perform a partial copy from external memory to internal memory. In step 114, it is checked whether CPREG is "1", and if YES, step 115
Proceed to , and check whether the pack code of PKCODE is "1" (registration data only) or "3" (both registration data and voice parameters).
Since CPREG is "1", this means that a partial copy of the registration data is requested, so it is checked in step 115 whether the registration data is stored in the external memory. If step 115 is YES, the process proceeds to step 116, where one bank PACKR of the external memory corresponding to the bank number stored in the partial copy bank number register PCBKNO is stored.
Read the resist data stored in (PCBKNO) and register data in RAM29.
Write to the storage areas (registration data memory) of RMEM1 to RMEM16.

In step 117, check whether CPVIC is "1", and if YES, proceed to step 118, and the pack code stored in PKCODE is "2" (voice parameters only) or "3" (both registration data and voice parameters). Find out if it is. If CPVIC is "1", this means that a partial copy of the voice parameters is requested, so it is checked in step 118 whether the voice parameters are stored in the external memory. If step 118 is YES, proceed to step 119, read out the voice parameters stored in one bank PACKV (PCBKNO) of the external memory corresponding to the bank number stored in register PCBKNO, and read out the voice parameters TCPW65~ in RAM29. Write to the storage area (voice parameter memory) of TCPW72.

In step 120, a display is made on the display 37 to indicate that the partial copy has been completed.

If a partial copy is to be performed from internal memory to external memory, step 113 is NO, and the process proceeds to step 121. Here, it is checked whether the bank for which partial copying is instructed is bank protected. Bank protect memory corresponding to the bank number stored in PCBKNO
Read the bank protect data BKPRO (PCBKNO) from BKPRO1 to BKPRO16 and check whether it is “0” (whether rewriting is prohibited)
Find out. If step 121 is YES, step 114a is almost the same as steps 114 to 119 described above.
~119a is executed to reach step 120. step
In steps 116a and 119a, writing is performed in the opposite direction to steps 116 and 119 described above. That is, step 116a

At step 123, the display 37 is caused to display a predetermined display indicating that partial copying is not to be performed.

<Bank protect function> When the enter switch ETR is turned on when MMNO=5, it is confirmed that the "bank protect" process will be performed, and the process advances from YES in step 124 to step 125 in FIG. ” is set. This starts the "bank protect" process. "Bank Protect"
The main information flow in processing is summarized as follows.
As shown in Figure 1.

In the state of MMNO=13, processing is performed to select a bank number for bank protection. 15th
At step 126 in the figure, the contents of the protect bank number register PRBKNO are set to the initial value "1". In the next step 127, the bank number stored in PRBKNO is displayed on the display 37. An example of this display content is shown in the block of step 127. “BANK” appears on the top of the display 37.
PROTECT” is displayed, and the bank number is displayed at the bottom.

When MMNO=13, the value of PRBKNO is changed by operating the data up switch DUP and data down switch DDW. When the data up switch DUP is turned on, YES in step 128 in FIG. 13 is passed and steps 129 and 130 are performed. This is similar to the processing in steps 83 and 84 described above, and 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, the first

By processing 134a and 135a, the specified bank protect memory BKPRO in external memory is
Reset the memory contents of (PRBKNO) to “0”. In this way, bank protection (rewriting prohibition) is canceled for the specified bank number.

When attempting to perform bulk copy or partial copy to a bank that has bank protection applied, in the case of partial copy, follow step 121 in Figure 13.
In the case of batch copying, step 144 in FIG. 17 becomes NO, and it is prohibited to proceed with the rewriting process. Rewriting is thus prohibited. If step 121 is NO, the process proceeds to step 146, where the display 37 displays the predetermined display "PARTIAL COPY" indicating that it is a partial copy, the display "BANK X" indicating the bank number, and the display "PROTECT" indicating that rewriting is prohibited. Perform the processing to display. If step 144 is NO, proceed to step 145, where the display "FROM EL TO PACK" indicating copying from the electronic musical instrument to external memory, the display "BANK X" indicating the bank number, and the display "PROTECT" indicating rewriting is prohibited. Processing is performed to display this on the display 37.

<Pack code writing function> When the enter switch ETR is turned on when MMNO=6, it is confirmed that the "pack code writing" process will be performed, and YES in step 147 in Fig. 15 is confirmed.
The process then proceeds to step 148, where the contents of the MMNO register are set to "15". This starts the "pack code writing" process.

In step 149, the pack code buffer is
Set the contents of PKCBF to the initial value "3". Pack code "3" is identification data indicating that the external memory stores both registration data and voice parameters, and is set as an initial value. However, without setting "3" as the initial value, the external memory side

Pack code is "3" (indicates register and voice) → "1" (indicates only register) → "2"
(Only the voice is shown) ->"3"->... The code changes in a cyclical manner, and one of the pack codes can be selected. Then, an identification display indicating the content of the selected pack code is made on the display 37) (steps 154, 158, 162).

When the menu down switch MDW is turned on, steps 151a, 156a to 158a in Fig.
Processes 155a, 160a to 162a, 159a, and 152a to 154a are executed. In this case, the menu down switch
Every time the MDW is turned on, the contents of the MMNO register change in the order of "15" → "17" → "16" → "15" →..., and accordingly the pack code of PKCBF changes from "3" to " The code changes cyclically in the order of ``2'' → ``1'' → ``3'' →..., and any one of the pack codes can be selected.

The pack code stored in the pack code buffer PKCBF is stored in the pack code memory of external memory.
When writing to PKCODE, press the enter switch.
Turn on ETR. If the enter switch ETR is turned on when the contents of the MMNO register are "15", "16", or "17", the contents of the MMNO register will change to "18" and the contents of the pack code stored in PKCBF will be changed. Displayed on the display 37,
Ask if this is okay (steps in Figure 15)
163-171). If that is OK, turn on the data up switch DUP. Then, in step 172 of FIG. 13, it is confirmed that MMNO=18, and the process proceeds to step 173, where the pack code of PKCBF is written into the pack code memory PKCODE of the external memory. In the next step 174, a predetermined end indication is made on the display 37. If you do not want to write the pack code displayed at step 171 (FIG. 15), turn on the data down switch DDW. Then, in step 175 of Figure 14, MMNO

A display indicating that the pack code has not been written is displayed on the display 37, and the process ends.

<Modification Example> In the above-described embodiment, the parameter information for setting the characteristics of musical tones is parameter information related to musical tone settings, that is, voice parameters and preset (registration) data. It can also be applied when dealing with. In other words, the parameter information for setting musical tone characteristics in the present invention includes all information related in some way to the setting of musical tone characteristics, including not only information related to musical tone settings but also volume, pitch, etc. , effects, automatic performance, rhythm performance, and other information related to setting, selection, and control of musical tone control functions. Therefore, the scope of the present invention includes handling of information for setting generation patterns of automatic arpeggio sounds and automatic rhythm sounds, for example. Therefore, the characteristics of the musical tone set by the parameter information supplied to the musical tone forming means include not only the characteristics of the musical tone components such as timbre, volume, and pitch, but also the generation pattern characteristics of rhythm sounds, etc. Also included.

Although the present invention is applied to a keyboard-type electronic musical instrument in the above embodiment, it can also be applied to non-keyboard-type electronic musical instruments. Further, an electronic musical instrument is interpreted in a broad sense, and may be a device forming part of an electronic or electric musical tone generating device or system.
For example, the present invention can be applied to sound source modules, rhythm machines, automatic performance devices, effect devices, and the like.

In the multi-menu switch section of Fig. 2, the desired menu or data is selected by changing the display contents of the display using the up/down switch as shown in Fig. 3. Alternatively, a numeric keypad switch or other appropriate data setting means may be used.

In addition, in the above embodiment, a multi-menu switch section is shared for various selection, setting, and control functions, but instead of using such a multi-menu type operator means, each function can be individually handled. A dedicated operator means may also be used.

In the above embodiment, various processes are performed under microcomputer control, but it goes without saying that similar processes may be performed using hardwired logic circuits. Furthermore, in the case of microcomputer control, the program flow of each processing routine is of course not limited to that shown in the drawings.

In the above embodiment, two types of tone setting parameter information are stored in the external memory, namely, registration data (preset data) and voice parameters, but this is not limited to automatic performance data, rhythm pattern data, Various setting/control parameter information related to the electronic musical instrument, such as chord (chord) pattern data, bass pattern data, setting/control data for various musical tone effects, etc., may be stored.

In the above embodiment, bank protection is applied to the external memory, but the rewriting prohibition process according to the present invention may be applied to the internal memory.

Further, the concept of banks is not limited to that shown in the embodiments, and may be classified in any manner. For example, in the case of registration data, in the embodiment, 16 sets of resist data (RMEM1 to RMEM16) are set as one bank, but each set of resist data that corresponds one-to-one to a registration switch may be set as one bank. , some suitable sets of resist data may be combined into one bank.
