Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a parameter generation device for an electronic musical instrument that generates parameter information for musical tone formation and control, and is capable of generating a large number of types of parameter information with a small memory capacity. This is what I did.

[Conventional technology]

As is well known, in order to generate musical tones, electronic musical instruments require a large amount of parameter information for setting and controlling various conditions such as the pitch, timbre, volume, and effects of musical tones.

Normally, this large amount of parameter information is generated in response to each control operation, but in order to easily generate parameter information, parameter information that has been arbitrarily set in advance is stored in memory. There is known a device in which the stored parameter information is read out by a simple switch operation and used for forming musical tones (Japanese Patent Publication No. 31475/1983).

[Problem to be solved by the invention]

However, in order to be able to arbitrarily generate a large number of musical tones with different musical tone characteristics, in conventional devices, a group of parameter information regarding the roaring musical tone characteristics is stored for each musical tone characteristic (each type of musical tone). This requires a large amount of memory.

For example, if 0 parameter information is required to generate one musical tone, then 10XIO-100 parameter information must be stored in order to be able to generate 10 different musical tones. It turns out.

Furthermore, since conventionally, the data stored in the memory is only parameter information, it was not easy to determine what the data was when used later.

This invention was made in view of the above-mentioned circumstances, and its purpose is to be able to generate a large number of parameter information groups with a small memory capacity, and to generate a large number of musical tones each having different musical tone characteristics on a small scale and at a low cost. An object of the present invention is to provide a parameter generation device for an electronic musical instrument that can generate parameters.

Another object of the present invention is to provide a parameter generation device for an electronic musical instrument that allows the contents of stored data to be easily known.

It was designed to be controlled.

Further, at least one of the voice parameters and performance parameters does not include auxiliary information for identifying and displaying the voice parameter or performance parameter, and further, the voice parameter read from the voice parameter storage means A display means is provided for displaying information or contents of the auxiliary information included in the performance parameters read from the performance parameter storage means.

[For production]

When a desired performance parameter is read from the performance parameter storage means by the performance parameter reading means, the voice parameter designated by the voice parameter designation information included in the read performance parameter is read from the voice parameter storage means.

Furthermore, since auxiliary information is displayed, the content of the parameter information can be easily determined.

When it is detected that a performance parameter information setting operation is being performed on the panel operation unit 5, the performance parameter information is stored in the storage location PCED of the working memory 102 in accordance with this setting operation.

When the central processing unit 100 detects that real-time parameter information is being set or changed on the first and second panel operation units 2.3 in the next step γ00, the central processing unit 100 updates the real-time parameter information in the new operation state. Working notes! J 102 at storage location RTMEM.

Then, in the next step 800, the voice parameter information and performance parameter information stored in the storage locations VCED and PCED are further stored in the storage location RT.

Note that the foot switch circuit 103. Key touch sensor 10
The output signal of No. 4 is converted into a digital signal in step 700 and then stored as one of the real-time parameter information.

FIGS. 7(,) and 7(b) are flowcharts showing details of voice memory processing. First, in step 301, the character switch 5W of the fourth panel operation section 5 is
It is determined whether or not the channel is in the on state, and if it is in the on state, switches SW1 to SW, and SW, 1 to 5 are used.
Since Wp8 is going to be used for inputting alphanumeric characters or numbers, step 310 in FIG. 7(a) is performed. In other words, character switch 5Wch
is turned on and performance parameter information is to be set using alphanumeric characters or numbers, the process jumps from step 301 to step 310.

However, if the character switch 5Wch is in the off state, the process advances to the next step 302, where the switches SW□ to SW8 . It is determined whether any of the above is turned on and is 9, and if it is turned on and 9, steps 303~
At step 309, voice parameter information is read or written. That is, character switch 5
If Wch is not on, swing fsW, ~SW8
m is a voice parameter information storage unit [VMEM(1)~
It functions as a switch that specifies one of the VMEMs (32). For this reason, switches SW0 to SW8. is turned on, the memory locations VMEM(1) to VM
If any one of EM (32) is designated, the process moves from step 302 to step 303, and the process of reading or writing voice parameter information is performed. However, if none of the switches SW5 to SW8 are turned on, the process jumps to step 310.

In the processing of steps 303 to 309, first step 30
3, set the contents of the conveyor flag CMP-F to “Oo
.

Then, initial settings are made when comparing the previously set nine voice parameter information with the newly set voice parameter information. After that, in step 304, the switches SW1 to SW8 . light emitting diode I
JD is turned on, and then in step 305 it is determined whether the store switch SW, t is turned on. If it is detected through this determination process that the store switch 5W8t is turned on, step 306

W, , , 6 memory locations VM
Write to EM (1') to VMEM (32). That is,
For example, when the switch SW1 is turned on and the store switch 5Wst is turned on, voice parameter information, which is the content of the storage section MV (JD), is written to the storage location VMEM (1) corresponding to the switch SW1. It will be done.

However, if one of the switches SW1 to SW, , is turned on, but the store switch SW,t is not turned on, steps 305 to 30
7, and the memory location VMEM (1) to V specified by the ON operation of switch SW 5W82
MEM (reads the voice parameter information from one of the 32'l, transfers it to the storage section fi VCK:D, and executes the process of storing it. In other words, the store switch SW
, t is not turned on, and for example, switch SW1 is turned on, the previously set voice parameter information is read from the memory location VMEM (1) corresponding to switch SW1, and is stored in the memory location VCED. Perform the processing to When the process of step 307 is finished,
In the following step 308, the contents of the memory location VCED are transferred to the electrical drive mechanism of each operator provided in the third panel operating section 4, and the operating position of each operator 9 is transferred to the memory location VCg.
It is automatically moved to a position corresponding to the memory contents of D. That is, when previously set voice parameter information is read out from one of the storage locations VMEM(1) to VMEM(32), the third panel operation unit 4 is read out in response to this content.
The positions of the respective operators RV, . . .

After this, in the next step 309, the memory location PCED
The memory location (VMEM(1"l~VMEM(32)
A process is performed to store a number VMN indicating any one of the following. As a result, the number VMN of the storage location of the voice parameter information used in combination with the performance parameter information is stored in the storage portion MVMN in the storage location PCED that stores the performance parameter information.

Therefore, when a desired storage location VMEM(1) to VMEM(32) is designated by the switches SW0 to SW82, voice parameter information is read from the designated storage location and transferred to the storage location VCED, and at the same time, the voice parameter information is read from the designated storage location and transferred to the storage location VCED.
The storage location number VMN of the voice parameter information currently being read into the CED is newly rewritten.

Here, voice parameter information storage location number VMN
The reason for rewriting is as follows. In other words, if all parameter information groups relating to a plurality of musical tones having different musical tone characteristics are to be stored for each musical tone, an enormous table memory capacity is required. However, in general, even though the musical tone characteristics are different, the parameter information groups are not all different, but often contain many common things. Therefore, parameter information that is relatively unimportant in determining musical tone characteristics and common to each musical tone characteristic is set as performance parameter information, while parameter information that is highly important in determining musical tone characteristics is set as performance parameter information. is set independently as voice parameter information. In other words, parameter information related to the tone quality (timbre, etc.) of a musical tone, which is relatively basic in determining musical tone characteristics, is set as a voice parameter, while parameter information related to various effects and musical tone control associated with performance operations that are not so closely related to the tone quality of the musical tone is set as voice parameters. The parameter information is set as a performance parameter.

By setting in this manner, parameters relating to a large number of musical tones can be generated with a small memory capacity by combining these performance parameter information and voice parameter information.

Here, 8 sets of performance parameter information and 32 sets of voice parameter information are combined to give a maximum of 2 sets of performance parameter information and 32 sets of voice parameter information.
It is configured to be able to generate parameter information regarding 56 types of musical tone characteristics.

Therefore, when configured in this way, either the performance parameter information or the voice parameter information requires information that determines the other party to be used in combination with the self. For this reason, a number VMN indicating the storage location of voice parameter information used in combination with the performance parameter information is stored in the storage location of the performance parameter information, and when certain performance parameter information is specified, this storage location number Poix compatible with VMN
Storage location VMEM (1) - VMEM
(32) and transferred to the storage location VCED which serves as an input/output buffer, and then transferred to the tone forming section 20 as a pair with the performance parameter information in the storage location PCED. In this case, the memory portion M′vMN
Instead of storing all storage locations of all sets of voice parameter information to be combined with the performance parameter information, only the newest specified voice parameter information storage location number VMN is stored.

For this reason, when new voice parameter information is read by turning on the switches SW1 to SW8°, the storage location number VMN stored in the storage part MVMN in the storage unit @PCED is updated in step 309. Ru.

In this way, in steps 303-309, switches SW1-SW8. The memory location corresponding to the on operation (V
MEM(1) to VMEM(32)) Voice parameter information reading or writing processing for K is executed.

When such processing is completed, the conveyor switch SW is turned on in step 310 shown in FIG. 7(b).
It is determined whether or not the on button has been turned on, and if the on button has not been turned on, the voice memory processing routine is terminated and the process moves to the next performance memory processing.

However, when the conveyor switch SWem is turned on, the most recently set voice parameter information and the previously set voice parameter information are compared with the compare switch SWem in steps 311 to 317.
Each time m is operated, it is alternately transferred to the musical tone forming section 20,
Processing is performed to alternately form musical tones corresponding to two pieces of voice parameter information and to compare the differences between the two.

f, that is, storage units fItVMEM(1) to VMEM(3
2) To change the voice parameter information previously stored in any of Otn, switch SW□ to SW8. After specifying the storage location with , perform an operation to newly set or change the voice parameter information using the operators RV, -RV14 of the third panel operation section 4, and then turn on the conveyor switches SWe, yl. Each time the switch is turned on, a process is executed in which the previous voice parameter information specified by the switches SW0 to SW8 and the newly set voice parameter information are alternately transferred to the storage location VCFD. That is, for example, memory location VMEM(1
) to change the voice parameter information stored in
When the switch SW is turned on, step 3 as described above will occur.
Through the processes from 03 to 309, the previously stored voice parameter information is read from the storage unit @vMEMQ) and transferred to the storage location VCED. After this, the operator RV, ~
When new voice parameter information is set by RV, 4, the new parameter information is stored in the storage location VCED in the voice parameter setting detection process 600 of FIG. Thereafter, when the conveyor switch SWem is turned on, the central processing unit 100 determines the contents of the conveyor flag CMP-F in step 311 of FIG. 3
At step 12, the new voice parameter information stored in the storage location VCED is saved to the storage location VCEDH, and then the previous voice parameter information stored in the storage location VMEM(1) is transferred to the storage location VCED. In this case, the storage location VMEM(1) of the old voice parameter information to be transferred to the storage location VCED; c. Storage location PC where all performance parameter information is stored; Turn on the tiger and it will be memorized immediately after operation. Therefore, the central processing unit 100
With reference to the memory location number VMN stored in the MN, the old voice parameter information is read from the memory location VMEM(1) and transferred to the memory location VCED. After this, in step 313, the conveyor 7 lug CMP-F-t-1''
Then, the light emitting diode LED of the conveyor switch 5Wern is turned on.

Once this processing is complete, performance memory processing (
Step 400) ~ Parameter sending process (Step 7O)
ff) is then executed, and the old voice parameter information stored in the storage location VCEI 7 is transferred to the tone forming section 20 in the parameter sending process (step 800).

After this, when the conveyor switch 5Wer11 is operated for the second time, the conveyor flag CM is activated in step 313.
Since P-F has been updated to IIIII, the process branches to step 315 based on the judgment in step 311, where the new voice parameter information saved in the storage location VCEDtl is restored to the storage location VCED. After that, in step 316, the conveyor flag CMP-F is changed to 1joll, and then in step 317
At this time, the light emitting diode LED of the conveyor switch 5wcm is turned off.

Once this processing is complete, performance memory processing (
Step 400) ~ Parameter transfer processing (Step 70)

00), the new voice parameter information in the storage location VCED is transferred to the tone forming section 20.

After this, when the conveyor switch SW is operated for 0 m for the third time, the same process as the first time is executed.

Therefore, every time the conveyor switch SWc is turned on, the old voice parameter information and the new voice parameter information are alternately transferred to the tone forming section 20. This makes it possible to alternately produce musical tones based on the old and new voice parameter information and to compare the differences between the two very easily.

When the voice memory processing is completed as described above, the 8th
The performance memory processing shown in the figure is executed.

That is, in step 401, it is determined whether or not the character switch 5Weh is in the on state, and if it is in the on state, the switches SW~5Wsfi and SW
Since 1 to 5Wp8 are going to be used for inputting alphanumeric characters or numbers, the process jumps to the performance parameter setting detection process (step 500) in FIG. 9(a).

However, if the character switch 5Wch is in the OFF state, the process advances to the next step 402, and switches SW, 1 to
It is determined whether any of the SWs, , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , 1, , , , , , 1, or 1 to That is, switch SWp l-8
When Wpa is turned on, the storage position P specified by the switches SW, 1 to SW, .
Performs processing to continue or write performance parameter information to MFM(1) to PMFM(8). However, if none of the switches SW, , -SW, 8 are turned on, the process jumps to the performance parameter setting detection process (step 500) in FIG.

In the processing of steps 403 to 407, first step 40
3, nine switches SW, 1 to SW,
After the light emitting diode LED 8 is turned on, it is determined in step 404 whether or not the store switch SW□ is turned on. If it is detected through this determination process that the store switch SW□ is turned on, the process advances to step 405, and the contents of the storage location PCED are transferred to the storage locations PMEM(1) to PMEM designated by the switches SW, 1 to SW, . Write in (8).

That is, for example, when the switch SW,1 is turned on and the store switch SWp is turned on, the performance parameter information, which is the content of the storage location PCED, is stored at the storage location PME corresponding to the switch 5Wp1.
M()).

However, if one of the switches SW, □ to 5Wp8 is turned on, but the store switch SW, , is not turned on, steps 404 to 40
6, and the memory locations PMEM(1) to PMEM specified by the ON operation of switches SW1 to SW, 8
(8) Read the performance parameter information from item 1, transfer it to storage location PCED, and store it.

That is, performance parameter information is read from storage locations PMEM(1) to PMEM(8) designated by switches SW,1 to SW,8.

After this, in the next step 407, the memory location P C
Refer to the memory location number VMN of the voice parameter information stored in the memory portion MVMN in the ED, and select the friend memory locations VMEM(1) to VMEM(1) corresponding to this memory location number VMN.
Extract voice parameter information from one of the VMEMs (32) and write it to storage location VCED. Through such processing, the memory location PCED has switches sw, 1
-5w, The desired performance parameter information designated by 8 is written, and at the same time, voice parameter information to be used in combination with the performance parameter information at this time is written into the storage section [VCED.

The performance parameter information and voice parameter information written in the storage locations PCED and VCED in this manner are transferred to the tone forming section 20 in the parameter sending process.

When the performance memory processing is completed as described above, the performance parameter setting detection processing (step 500) shown in FIGS. 9(&) and (b) is executed.

This performance parameter setting detection process can be roughly divided into a first part that selects a parameter fund using switches SWm1 to SWm8 and displays it on the display device LCD, and detects parameter information set corresponding to the selected parameter name. It consists of a second part.

FIG. 9(1k) is a flowchart showing the first part of the process, in which it is determined in steps 501 to 508 whether any of the switches SWm□ to SWm8 has been turned on. As a result of this determination, for example, if it is found that the switch 5Wrr10 has been turned on, the process proceeds to step 509, a first mode parameter name display process. Similarly, step 510. ...516 2nd to 8th
Proceed to mode parameter name display processing. Then, the parameter salts assigned in advance by the store to each of these parameter display processes (steps 509 to 516) are displayed on the liquid crystal display L.
Display on CD.

In this case, each of the parameter display processes in steps 509 to 516 is configured to be able to sequentially display a plurality of parameter salts, and each of these parameter salts is connected to the switch SWm.
1 to SWm8 are selectively displayed according to the number of times the same switch is turned on.

In other words, for the switch 5Wrn1 that displays the parameter salt of @1 mode, Fig. 10 (jk) to (c)
As shown in the figure, display parameter values are assigned to selectively display transposition information, tone name information, and performance memory information. Also, a switch SW□ for displaying the parameter salt of the second mode.

As shown in FIGS. 11(g) to 11(g), pinch bender range information and pitch bender step information are provided.

Seven display parameters are assigned to selectively display key touch sensitivity information, brilliance information, modulation wheel control ffN, Funtosuit control m information, and key touch control information.

Furthermore, for the switch 5Wrn8 that displays the parameter salt of the third mode, 812 (a) to (c)
As shown in K, three display parameter values are assigned to selectively display LFO waveform selection information, LFO phase control information, and LFO pitch modulation information. Furthermore, as shown in FIG. 13, a display parameter salt is assigned to the switch 5Wr114 for displaying the parameter salt in the fourth mode so as to display sound effect selection information. Similarly, a plurality of display parameter salts are also assigned to switches SWm5 to SWm8 that display parameter salts of eight modes in the fifth mode to SWm8. Note that the display parameter salts assigned to the switches SW1-5Wn18 and their explanations will be omitted.

The process of selectively displaying a plurality of parameter salts in this way will be explained using the first mode parameter name display process in step 509 as a representative. First, in step 5090, the contents of the job flag MI JOB-F in the first mode are by adding “+1” to the corresponding flag MI JOB, F
In addition to updating the contents of job flag M for other modes.
2 JOB-F-M3 Clear the contents of JOB-F. When the switch SWm1 is turned on once, the job flag MI JOB-F of the first mode is set.
17) The content changes from rOJ to "1", while the contents of job flags M2 JOB-F-M8 JOB-F in other modes all become "0". Then, when the switch SWm is turned on twice, three times, and four times in succession, the contents of the job flag MI JOB,F are sequentially updated as r2J, r3J, r4J each time the switch SWm is turned on. Ru.

When such job flag update processing is completed, in the next step 5091, the first mode job flag MI
It is determined whether JOB and F are "4". That is, the number of display parameter values assigned to the first mode parameter name display process is three, as shown in FIGS. 10(a) to 10(e). Therefore, switch SWm1 is set to 4
If the operation is performed twice, in order to return the display contents of the display device [LCD to the initial state, it is determined whether the content of the job flag MI JOB-F in the first mode is "4" or not. be done.

Incidentally, in the initial state, musical tone name information and transposition information are displayed on the display device LCD as shown in FIG. 14.

As a result of the determination in step 5091, job flag M1
If the content of JOB-F is one of "1" to "3", the process advances to step 5094. Here, the contents of the job flag MI JOB-F are "1" to "3".
It is determined which one of these applies, and the processing in steps 5095 to 5097 is selected according to the determination result. As a result, if step 5095 is selected, FIG.
Parameter salts of the transposition information as shown in step 3 are displayed on the display device LCD, and step 509
If you select 5 and just in case, the parameter value of musical note name information as shown in FIGS. 10-) will be displayed. Similarly, when step 5097 is selected, the parameter information of the performance memo information as shown in FIG. 10(c) is displayed.

However, as a result of the determination in step 50910, if the content of the job flag MI JOB-F is "4", the content of the flag MI JOB-F is set to rOJ in step 5092, and then the process proceeds to step 5093, where mode 0 is set to rOJ. The display, that is, the display content in the initial state as shown in FIG. 14 is displayed.

Through such processing, each parameter value of transposition information, tone name information, and performance memo information is selectively displayed depending on the number of times the switch SWm is turned on.

Similarly, parameter salts [first
1 to 13) are selectively displayed.

When the desired parameter salt has been displayed through such processing, the cursor display is moved up and down or left and right in step 517. In other words, when SWIN+SWe, ~5We4 is operated to specify the display position of parameter information set using numbers or letters, the cursor display will be changed according to the operation status of this switch. move it. In addition, in FIGS. 10 to 14, the cursor display is indicated by the symbol CS.

Next, in step 518, job flags MI JOB, F-M8 JOB, F for the first mode to the eighth mode are set.
It is determined whether the contents of are all "0" or not, and if it is "0", it is assumed that no operation for setting parameter information has been performed, and the process moves to step 600 in the main routine of FIG. .

However, if some parameter name is displayed by operating switches 5WIT and 1-1-8W, it means that an operation is being performed to set parameter information corresponding to the displayed content. Therefore, Figure 9(b)
The process advances to step 519 of the flowchart shown in FIG.

In the flowchart of FIG. 9(b), first, in step 519, it is determined whether or not the character switch 5Wch is turned on. As a result, when the character switch 5Wch is turned on, nine parameter information corresponding to the parameter information displayed on the display device LCD is displayed on the switches 5WI-8W8. and 5
Since it is about to be set by Wl-8W, 8, in steps 520, 521...!
@1 mode to 8th mode job flag MI JOB
, F-M8 JOB, and F are examined to determine which mode of setting parameter information is being performed.

As a result of this determination, the $1 mode job flag MI J
If the contents of OB and F' are not "0", it means that the parameter information in the first mode is about to be set, so the process proceeds from step 520 to step 527, where the switches SW0 to SW+1° and SW1 are set. ~
5Wp8 is detected, and alphanumeric or alphanumeric parameter information corresponding to the on operation of these switches is stored in the storage unit 1jiP (predetermined storage portion in JD) in the working memory 102.

This further processing is performed using the job flag M2 JO of each mode.
Even if the contents of B-F-M8 JOB-F are not "0", steps 528 to 534 corresponding to each job flag are executed in the same way.

Shikashi, display device LCD KM I 01ffl(a)
~l1c13 If any of the parameter salts shown in the diagram is displayed, but the character switch 5Weh is not turned on, it is determined in step 525 whether or not the character switch 5Wch remains off for 10 seconds or more. . As a result, if the OFF state of switch 5Wch continues for 10 seconds or more, the operation for setting parameter information is interrupted or terminated, and as a precaution, all job flags MI J are set in the next step 526.
OB-F-M8 After clearing the contents of JOB-F, change the display contents of the display device LCD to the display contents of mode 0 (
The display contents are returned to the initial state (see FIG. 14), and the process proceeds to step 600 of the main routine in FIG. However, if the duration of the off state of the character switch 5Wch is less than 10 seconds, it is assumed that the parameter information setting operation is in progress, and the display contents on the display device @LCD are maintained as they are, and the process proceeds to step 600 of the main routine in Figure M6. move on. In other words, the ON operation of the character switch 5Weh is repeated 10 times.

If any one of SW, 1 to SW, , is turned on, in step 52T2, numerical or alphanumeric parameter information corresponding to that operation switch is displayed at the cursor display position on the display device LCD.

Subsequently, in step 5273, numerical or alphanumeric parameter information is stored in the memory portion MPP in the memory location PCED.

Proceed to step 600 of the main routine of the figure.

Such processing is similarly executed in the processing of steps 5274 and 5275 even if the contents of the job flag MI JOB-F are "2J, r3J tone name information, performance memo information. M2
The same applies to JOB-F-M8 JOB-F.

The performance parameter information set as described above is stored in one of storage locations PMEM(1) to PMEM(8) by performance memory processing in step 400 in the next program cycle in the main routine.

In this way, the parameter setting unit 10 uses a common display device and information setting switches for multiple sets of performance parameter information, so even when there is a wide variety of performance parameter information to be set, The panel operation section can be extremely simplified.
