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 controller is operated, parameter information (for example, voice parameters) that sets the musical tone characteristics assigned to that controller is given to the musical tone forming circuit, and based on this parameter information, the musical tone characteristics are set. is 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 is read out all at once and used for setting musical tone characteristics. Electronic musical instruments equipped with a preset function have also been known for some time. 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 pulled out 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 (e.g., magnetic card, non-volatile memory, battery-backed semiconductor memory, etc.) is required. ), various parameter information and preset data are stored in the electronic musical instrument, 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 can be appropriately rewritten (set) in accordance with the operation of a predetermined operator. Furthermore, the parameter information set in the internal storage device in this manner is also transferred to an external storage medium and stored there. Such parameter editing devices are disclosed in, for example, Japanese Patent Application Laid-open No. 56-52800 and Japanese Patent Laid-Open No. 59-137993.

<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, first, the contents of various registers in the RAM 29 are initialized, and then a scanning process S1 of the timbre switch section 22 is performed. Here, any tone switch TC5WI~8
When the on event is detected, the tone switch on event subroutine shown in 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, the menu up switch MUP
When an on event of the menu down switch MDW is detected, the subroutine of FIG. 11 is executed, and when an on event of the menu down switch MDW is detected, a subroutine of FIG. 12 is executed, and an on event of the data up switch DUP 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 ETH is detected, the subroutine of FIG. 15 is executed. The subroutine is executed.

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

Next, other control section 25 related to the multi-menu
scanning processing is performed, and further scanning processing is performed on the other operating elements 26. Next, processing related to the voice parameter creation device 33 is performed. In this process, voice parameters created according to the player's preferences are written into the RAM 29 as voice parameters TCPW (65) to TCPW (72). Finally, the key switch circuit 20 is scanned, and based on the scan results, sound generation is assigned to each channel.

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

First, the number of the turned-on tone color switch (any one of TC8WI-TC8) is stored in the TC8W register, and then the LED corresponding to the turned-on tone color switch is lit. Next, it is checked whether the number stored in the TCSW is 7 or more (step 38).

If it is 7 or above, white switch TC8W7 or TCS
This means that W8 has been turned on, and if it is less than 7, then the normal tone switches TC5WI to TC8W6 have been turned on.

If the white switch is turned on, proceed to step 39 and set the multi-menu number 1 in register MMNO to "1".
Set to . In step 4o, a white switch assignment tone code register WHTC (7) corresponding to the switch number (7 or 8) stored in register TC8W is entered.

It changes depending on the contents of H.

Through this process, the white switch TC5W is turned on.
The name of the tone currently assigned to TCSW 7 or TCSW 8 is displayed on the multi-menu display 37. Step 4
2, the voice parameter (one of TCPW (1) to TCPW (72), indicated by TCPW (TCCODE)) corresponding to the tone code of TCCODH is read from the internal RAM 29 or ROM 30, and this is used to create the musical tone. The signal is supplied to a generation circuit 34 (designated TO). As a result, the tone of the musical tone signal generated by the musical tone generating circuit 34 is set according to the voice parameter assigned to the white switch that has been turned on.

If the turned-on tone switch is not a white switch, the process proceeds from step 38 to step 43, where the contents of register MMNO are reset to "0". In the next step 44, the number of the on-switch stored in TCSW is reset. The voice parameter (any one of TCP (1) to TCP (6), which is indicated by TCP (TCSW)) corresponding to (any one of 1 to 6) is stored in the ROM.

The pack insertion event routine shown in FIG. 9 will be explained. When it is detected that the external memory 31 has been inserted, "2" is set in the multi-menu number register MMNO (step 45).
Read the backcoat from memory PKCODE of 1,
In step 47, information identifying the type of the external memory pack is displayed on the display 37 according to the read backcoat. At this time, the display contents of the display 37 are as shown in step 4.
As shown in the example in block 7. In this display, rRAM PACKJ in the upper row indicates that the external memory pack consists of readable and writable RAM, and r-REGI ST&VOICE-J in the lower row indicates that the type of parameter information stored in the external memory pack is registration data and voice parameters. Indicates that both, if
If the external memory pack consists of ROM, the upper display will be rROM PACKJ. Furthermore, if the stored parameter information is only registration data, the lower display will be r-REG I 5T-J, and if only voice parameters are stored, it will be r-VOICE-J. In this embodiment, the types of RAM type external memory packs are the three types mentioned above.
FIG. 18(a) shows the type and identification information displayed on the 1 display 37.

(b) and (C). In this way, information identifying the external memory pack is automatically displayed when the pack is attached to the electronic musical instrument, without requiring any special switch operations.

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

First, the registration switch REGS is turned on.
The number of W is stored in register REGNO (step 48). Next, in step 49.

Check whether the memory switch MSM is currently being turned on. If YES, the process proceeds to step 50, where one set of registration data is written; if no, the process proceeds to steps 51 and 52, where one set of registration data is read. In step 50, the registration data is written. A set of registration data (RMEM (1) to RME
M (16) and 1 number 1 to 16 is REGNO
Since it is specified by RMEM
(denoted as REGNO)) is written into the registration data memory of the RAM 29.

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 number of the turned-on registration switch stored in the register REGNO is transferred to the RAM 2.
Read from 9.

In accordance with the contents of this registration data, display of the setting states of predetermined switches, operators, etc. on the panel section 21 is controlled, and the settings of the registration data are clearly shown to the performer.

In step 53, the read registration data RMEM
Parameter information corresponding to (REGNO) is supplied to the musical tone generation circuit 34. In this way, various 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 for each of the nine functions.

Tone assignment function to white switch> When the white switch TC5W7 or 8 is turned on, the multi-menu number MM is
NO 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 the white switch TC8W7 or 8 is turned on, the corresponding white switch tone code register WHT
The tone color code currently assigned to C(7) or (8) is read out, and this is stored in the multi-menu tone code register TCCODEL:X door.

TCCODE+71 One set of voice parameters TCPW (1) to TCPW (72) according to the tone code
is read out.

This is 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 this mode, depending on the operation of the menu up switch MUP or menu down switch MDW, TCCOD
By changing the contents of H, the voice parameter TC
Select a desired tone from among the 72 tones corresponding to PW (1) to TCPW (72). The name of the selected tone is displayed on the display 37), and at the same time register WHTC (

In addition, since the maximum value is 72, when the added value exceeds 72, it shall return to the maximum lJS value of 1.0th step 5
In step 6, the tone color code TCCODE is registered (assigned) to the register WHTC (TC8W) corresponding to the turned-on white switch. In the next step 57, the voice parameter TCPW (TCCODE) corresponding to the tone color code of TCCODH is read out of the voice parameters TCPW (1) to TCPW (72), and the tone color name thereof is displayed on the display 37. In step 58, the voice parameter TCPW (TCCODE) is input to the musical 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, but step 55a corresponding to step 55 is different. In this step 55a, the value of the tone color code of TCCODE is decreased by 1. Note that since the minimum value is 1,
When the subtraction value is less than 1, it returns to the maximum value 72.

<Functions when inserting an external memory pack> When an external memory pack is inserted, the MMNO becomes "2" by the process of step 45 (FIG. 9) described above. At this time, the external memory pack is identified. It has already been described that information is displayed on the display 37.

When MMNO=2, when confirmation switch CFSW or from-back switch FPSW is turned on.

The contents of the multi-menu number register MMNO are changed to "3", and a mode is entered in which the multi-menu switch unit 23 can be used to specify a desired bank number. This bank number can be specified using the data up switch DUP.
Alternatively, it is performed by operating the data down switch DDW.

When the from bank 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 BANKNO

Now, the identification information corresponding to the bank code stored in PKCODH is displayed on the upper stage of the display 37, and BANKN
The bank number stored in O is displayed on the lower part of the display 37. In the block of step 62, an example of the display contents of the display 37 is shown. Note that in the figure showing the display contents on the 1 display 37, appropriate numerical values according to the contents of the bank number register and appropriate characters according to the contents of the back coat register are shown.

M M N O= 2 (7) Toki TIL edict A y
When the switch CFSW is turned on, steps 59a to 62a in FIG. 17 are performed in the same manner as steps 59 to 62 in FIG. 16.

Note that even if MMNO is not 2, it is in a mode other than parameter editing (if the MMNO value is 19 or more, the multi-menu is being used for purposes other than parameter editing).
is set to MMNO=3 through the YES route in steps 177 and 1778 (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 advances from YES in step 63 in FIG. 13 to step 64, and the BANKN
Increase the bank number of O by 1. Here, since the maximum bank number is 16, when the added value exceeds 16, it returns to 1. In step 65, the display of the bank number in the lower row of the 1 display 37 is rewritten with the new contents of ANKNO. When the data down switch DDW is turned on, steps 63a to 65 in FIG.
Steps 63 to 65 in FIG. 13 are processed by step a. The difference is that in step 64a, BANKNO
The bank number 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 MMN○ is "3".

A desired bank number can be specified by operating switches DUP and DDW, and this is stored in BANKNo. The bank number stored in BANKNO indicates the bank in which information is exchanged in bank units between the external memory and the internal memory in the 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 back switch FPSW. As mentioned above, B

From YES in step 82 of FIG. 13, the process proceeds to step 83, where the bank number of PCBKNO is incremented 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 on the lower part of the display 37 is changed to a new P.
Rewritten according to the contents of CBKNO. When the data down switch DDW is turned on, steps 82a to 84a in FIG. 14 are followed by steps 82 to 84a in FIG.
It is processed almost in the same way as 84. The difference is step 83
The bank number of PCBKNO is decreased by 1 in step a. In this case, since the minimum bank number is 1, when the subtracted value is less than 1, it returns to the maximum value 16. In this way, select the bank number where you want to copy one part, and
Store in NO register.

Note that the method of circulating to the maximum value or minimum value when the minimum value 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 you have finished selecting the bank number, press the enter switch ET.
Turn on R and switch MMNO to "8" (steps 85 and 86 in FIG. 15). In step 87, the contents of the partial copy designation registers CPREG and CPVIC are

When the enter switch ETR is turned on when the MMNO is "10" or "11", the MMNO changes to "12" and a display for confirming the direction of one partial copy is made on the display 37 (steps 106 to 15 in FIG. 15). 111) If the displayed direction is acceptable, turn on the data up switch DUP, and if not, turn on the data down switch DDW.

When the data up switch DUP is turned on when MMNO=12, step 112 in FIG. To perform a partial copy, proceed to step 114;
In step 114, it is checked whether CP RE G ffi is "1", and if YES, the process proceeds to step 115, and the PK
Check whether the CODH backcoat is "1" (registration data only) or "3" (both registration data and voice parameters). CPREG is “1”
Since a partial copy of the registration data is requested, it is checked in step 115 whether the registration data is stored in the external memory. Step 115 is Y
If ES, the process advances to step 116 and one bank PACKR (PCB

Write to the storage area (registration data memory) of EM (16).

In step 117, it is checked whether CPVIC is "1", and if YES, the process proceeds to step 118, and if the backcoat stored in PKCODE is "2" (voice parameters only) or "r3" (both registration data and voice parameters). Find out if there is one. Since CPVIC is 1'', it is requesting a partial copy of the voice parameters, so it is checked in step 118 whether the voice parameters are stored in the external memory.Step 118 is YES.
If ES, proceed to step 119 and register PCBK.
The voice parameters stored in one bank PACKV (PCBKNO) of the external memory corresponding to the bank number stored in NO are read and the voice parameters TCPW (65) to TCPW (72) in the RAM 29 are read.
write to the storage area (voice parameter memory).

In step 120, a message is displayed on the display 37 indicating that the partial copy has been completed.

If a partial copy is to be performed from the internal memory to the 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. PC
Bank protect memo IJBKPRO(1) to BKPRO(1) corresponds to the bank number stored in BKNO.

Check whether rewriting is prohibited. Step 1
If 21 is YES, execute steps 1148 to 119a, which are almost the same as steps 114 to 119 described above,
Step 120 is reached. In steps 116a and 1198, writing is performed in the opposite direction to steps 116 and 119 described above. That is, in step 116a, internal RAM2
In step 119a, 16 sets of registration data RMEM (1) to RMEM (16) are read from the registration data memory No. 9 and written to the registration data bank PACKR (PCBKNO) specified by PCBKNO of the external memory. 8 sets of voice parameters TCP from parameter memory
W (65) to TCPW (72) are read and written into the voice parameter bank PACK'V (PCBKNO) L: instructed by PCBKNO in the external memory.

When the data down switch DDW is turned on when MMNO=12, step 122 in FIG. 14 becomes YES, and the process proceeds to step 123. In step 123, a predetermined display indicating that partial copying will not be executed is displayed on the display 37. Let it happen.

Bank protect function> When the enter switch ETR is turned on when MMN○=5, it is confirmed that the “bank protect” process will be performed.
・From YES in step 124 in Figure 15 to step 12
5, the contents of the MMNO register are set to "13". This starts the "bank protect" process. The main information flow in the [Bank Protect] process is schematically shown in FIG. 21.

In the state of MMNO=13, processing is performed to select a bank number for bank protection. In step 126 of FIG. 15, the protect bank number register PRBKNO

The value of KNO is changed. Data up switch DUP
is turned on, YE in step 128 in FIG.
S and performs the processing of steps 129 and 130, which 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, the same processing as steps 128 to 130 in FIG. 13 is performed. However, in step 129a, PRBKNO
Decrement the bank number by 1.

When you have finished selecting the bank number, press the enter switch ET.
Turn R on L and switch MMNO to "14" (15th
Steps 131 and 132 in the figure).

In step 133, the bank number for which bank protection is to be performed (ie, the bank number stored in PRBKNO) is displayed on the display 37, and a question is asked as to whether bank protection is to be performed.

When the data up switch DUP is turned on when MMNO=14, it means that bank protection has been selected for the bank number stored in PRBKNO, and the process goes from YES in step 134 to step 135 in FIG. Then, among the bank protect memories BKPRO (1) to BKPRO (16) (Fig. 6) in the external memory, the signal “1” is set to the one corresponding to the bank number of the register PRBKNO (this is indicated by BKPRO (PRBKNO)). In this way, it is stored that bank protection (rewriting prohibited) should be performed for the designated bank number. On the contrary, data down switch DDW
is turned on, steps 134a and 135 in FIG.
By the process a, the stored contents of the designated bank protect memory BKPRO (PRBKNO) in the external memory are reset 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, step 121 in FIG. 13 will be No in the case of partial copy, and No in step 144 in FIG. 17 in the case of bulk copy. Therefore, proceeding to the rewriting process is prohibited. Rewriting is thus prohibited. If step 121 is No, the process advances to step 146, where a predetermined display indicating that it is a one-part copy rPARTIAL C0PYJ and a display indicating the bank number rBANK XJ and a display indicating that rewriting is prohibited r
PROTEcTJ is displayed on the display 37. If step 144 is NO, the process advances to step 145, where the display 37 displays rFROM EL To PACKJ, a display indicating copying from the electronic musical instrument to the external memory, rBANK XJ indicating bank number, and PROTECTJ indicating prohibition of rewriting. Perform the processing to display.

Back coat writing function> When the enter switch ETR is turned on when MMNO=6, it is confirmed that the back coat writing process will be performed, and from YES in step 147 in FIG. 15, step 1 is executed.
The process advances to step 48, where the contents of the MMNO register are set to "15". This starts the "backcoat writing" process.

In step 149, the contents of the back coat buffer PKCBF are set to an initial value "3". Back coat "3"
is identification data indicating that the external memory stores both registration data and voice parameters, and this is set as the initial value. However, instead of setting "3" as the initial value, the backcoat currently stored in PKCODH on the external memory side may be set as the initial value in PKCBF.

In step 150, rPACK C0DE EDITJ is displayed in the upper part of the multi-menu display 37, and identification information corresponding to the back coat stored in PKCBF is displayed in the lower part, for example, in the case of back coat "3", rREGIS is displayed.
Display T & VOICEJ. In this state, the back coat of PKCBF can be changed by operating the menu up switch MUP and the menu down switch MDW.

Steps 151-154, 155-158 in FIG.
As is clear from the processing in steps 159 to 162, each time the menu up switch MUP is turned on, the contents of the MMNO register change from "15" to "16" to "17" to "15" to
The back coat of PKCBF changes to "3" (indicating resist and voice).
→ "1" (representing only the resist) → "2" (representing only the voice) → "3" → ... The back coat changes in the order of cyclical order, and one of the back coats can be selected. Then, an identification display indicating the contents of the selected back coat is made on the display 37 (steps 154, 158, 162).

→ "15" → ..., and as a result, the back coat of PKCBF changes from "3" → "2" → "1".
”→“3”→..., and it is possible to select one of the back coats.

When writing the backcoat stored in the backcoat buffer PKCBF to the backcoat memory PKCODE of the external memory, the enter switch ETR is turned on.

The contents of the MMNO register are r15J, r16J, r
When the enter switch ETR is turned on at any time of 17J, the contents of the MMN○ register are changed to 1184,
The contents of the back coat stored in PKCBF are displayed on the display 37, and an inquiry is made as to whether this is OK (first
Steps 163-171 in Figure 5). If that's okay,
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 PKCBF

to complete the process.

Example of Modification> In the embodiments described above, the parameter information for setting the characteristics of musical tones is parameter information related to tone settings, that is, voice parameters and preset (registration) data. It can also be applied when handling That is,
The parameter information for setting musical tone characteristics in this invention is as follows:
It contains all the information related in some way to the setting of musical tone characteristics, not to mention information related to timbre settings,
Information related to setting, selection, and control of volume, pitch, effects, automatic performance, rhythm performance, and other musical tone control functions. Therefore, the scope of the present invention also includes handling of information for setting generation patterns of, for example, automatic albejo sounds and automatic rhythm sounds.

Therefore, the musical tone characteristics set by the parameter information supplied to the musical tone forming means include not only the characteristics of the musical tone constituent elements such as timbre, volume, and pitch, but also the generation pattern characteristics of rhythm tones and the like.

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 shown in Figure 2, the desired menu or data is selected by changing the display contents on the display using the up/down switch as shown in Figure 3. A switch or other appropriate data setting means may be used.

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

In the embodiments described above, various processes are performed under microcomputer control, but it goes without saying that similar processes may be performed using hard-wired logic circuits. In addition, in the case of microcomputer control,
Of course, the program flow of each processing routine is not limited to that shown in the figures.

In the above embodiment, two types of tone setting parameter information, namely, registration data (preset data) and voice parameters, are stored in the external memory.
It stores various setting and control parameter information related to electronic musical instruments, including, but not limited to, automatic performance data, rhythm pattern data, chord pattern data, bass pattern data, and setting and control data for various musical sound effects. You can do it like this.

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.

Furthermore, the concept of banks is not limited to that shown in the examples.
It doesn't matter how you classify it. For example, in the case of resist data, in the embodiment, there are 16 sets of resist data (RM
EMI to RMEM16) are set as one bank, but each set of registration data that corresponds one-to-one to the registration switch is set as one bank, or the register data of a suitable credit union is set as one bank. It's okay.
