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.

This large amount of parameter information is normally 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, and this stored parameter information can be read out with a simple switch operation and used for musical tone formation. A device designed to do this is known (Japanese Patent Publication No. 55-31475).

[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, with conventional devices, it is necessary to store a group of parameter information regarding each musical tone characteristic for each musical tone characteristic (each type of musical tone). This requires a large amount of memory.

For example, if 10 pieces of parameter information are required to form one musical tone, in order to be able to generate 10 types of musical tones, 10 x 10 = 100
This means that parameter information for each item must be stored.

Furthermore, since conventionally, the data stored in memory is only parameter information, it is 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.

On the other hand, the program memory 101 stores control programs for performing the processes shown in the flowcharts of FIGS. 6 to 9.
As shown in FIGS. 10 to 14, information for displaying selected parameter names and the like on the display device LCD is stored in advance as fixed information.

The operation of the parameter setting section 10 configured as described above will be explained based on the flowcharts shown in FIGS. 6 to 9.

First, the central processing unit 100 performs voice memory processing, performance memory processing, performance parameter setting detection processing, voice parameter setting detection processing, real-time parameter setting detection processing, parameter Execute the sending process repeatedly.

Then, in step 300, when it is detected that voice parameter information is being read or written, the voice parameter information is read or written to the specified storage location. Furthermore, when it is detected that an operation for comparing previously stored voice parameter information and newly set voice parameter information is being performed, these two pieces of voice parameter information are alternately stored in the tone forming section 20. Perform processing to transfer to.

Next, in step 400, when it is detected that performance parameter information is being read or written, the performance parameter information is read or written to the specified storage location. Also, in the next step 500, the fourth panel operation section 5
When it is detected that the performance parameter information setting operation is being performed, the message ``According to this setting operation, the performance parameter information is stored in the storage location PCED of the working memory 102.

At 600, when it is detected that voice parameter information is being set or changed on the third panel operation section 4, the voice parameter information in the new operation state is stored in the storage location VCED of the working memory 102. Note that this memory location
When the store switch SW _st is pressed and the storage location is specified by switches SW ₁ to _{SW 32} , the latest set voice parameter information stored in the VCED is stored in a predetermined storage location by the process of step 300. It is stored in positions VMEM1 to VMEM32.

Then, in the next step 800, the memory location
Voice parameter information and performance parameter information stored in VCED and PCED, as well as real-time parameter information stored in storage location RTMEM, are transferred to musical tone forming section 20.

Note that the output signals of the foot switch circuit 103 and the key touch sensor 104 are converted into digital signals in step 700 and then stored as one piece of real-time parameter information.

FIGS. 7a and 7b are flowcharts showing details of voice memory processing.
At 301, it is determined whether or not the character switch SW _ch of the fourth panel operation section 5 is in the on state, and if it is in the on state, the switches SW ₁ to SW ₃₂ and SW _p1 to _{SW p8} are input with alphanumeric characters or numbers. Since it is about to be used for the following purposes, the process jumps to step 310 of FIG. 7b. In other words, when the character switch SW _ch is turned on and performance parameter information is to be set using alphanumeric characters or numbers, step 301 is executed.
Jump to step 310.

However, if the character switch SW _ch is in the OFF state, the process proceeds to the next step 302, where it is determined whether any of the switches SW ₁ to _{SW 32} has been turned on. In steps 303-309, voice parameter information is read or written. That is,
If the character switch SW _ch is not on,
The switches _SW1 to _SW32 function as switches for specifying one of the voice parameter information storage locations VMEM1 to VMEM32. Therefore, one of switches SW ₁ to SW ₃₂ is turned on,
If any of the storage locations VMEM1 to VMEM32 is designated, the process moves from step 302 to step 303, where voice parameter information is read or written. However, Switch SW ₁ ~
If none of SW ₃₂ is turned on, the process jumps to step 310.

In the processing of steps 303 to 309, first step
In step 303, the content of the compare flag CMP.F is set to "0" to perform initial settings when comparing previously set voice parameter information and newly set voice parameter information. After this, step
Switches SW ₁ to SW ₃₂ turned on at 304
Then, in step 305, it is determined whether the store switch SW _st is turned on. When it is detected through this discrimination process that the store switch SW _st is turned on, the contents of the storage location VCED are transferred to the storage locations VMEM1 to VMEM32 specified by the switches SW ₁ to _{SW 32} in step 306.
write to. That is, for example, when switch SW ₁ is turned on and store switch SW _st is turned on, voice parameter information, which is the content of storage location VCED, is written to storage location VMEM1 corresponding to switch SW ₁ . .

However, if one of the switches SW ₁ to _{SW 32} has been turned on, but the store switch SW _st has not been turned on, the process branches from step 305 to step 307, and when the switches SW ₁ to _{SW 32 are turned on, the process branches to step 307} . The memory location specified as VMEM1
~ Execute processing to read voice parameter information from one of the VMEMs 32, transfer it to the storage location VCED, and store it. In other words, store switch SW _st is not turned on and, for example, switch SW ₁
is turned on, the previously set voice parameter information is read from the memory location VMEM1 corresponding to switch SW ₁ , and it is stored in the memory location.
Perform processing to store in VCED. This step
When the process in step 307 is completed, in the following step 308, the contents of the memory location VCED are transferred to the electric drive mechanism of each operator provided in the third panel operating section 4, and the operating position of each operator is transferred to the memory location VCED. automatically move to a position corresponding to the stored contents. That is,
When previously set voice parameter information is read from one of the storage locations VMEM1 to VMEM32, the third panel operation section 4
The positions of each of the operators RV ₇ to RV ₁₄ are automatically moved so that it is possible to know what operator state the parameter information read at this time corresponds to.

After this, in the next step 309, the memory location is
For the storage part MVMN in PCED, the storage location (VMEM1~
VMEM 32). 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 the desired storage locations VMEM1 to VMEM32 are specified by the switches _SW1 to _SW32 ,
The voice parameter information is read from the specified storage location and transferred to the storage location VCED, and the storage location number VMN of the voice parameter information currently read out is rewritten to the storage location PCED.

Here, voice parameter information storage location number
The reason for rewriting VMN is as follows. That is, if it were attempted to store all the parameter information groups regarding a plurality of musical tones each having different musical tone characteristics for each musical tone, an enormous memory capacity would be required. However, in general, even though the musical tone characteristics are different, the parameter information groups are not all different, but often include many things in common. 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 voice parameters, while parameters 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 are set as voice parameters. The 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.
The configuration is such that 8 sets of performance parameter information and 32 sets of voice parameter information can be combined to generate parameter information relating to a maximum of 256 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 Voice parameter information corresponding to VMN is stored in storage locations VMEM1 to VMEM
32 and transfers it to the storage location VCED, which serves as an input/output buffer, and pairs it with the performance parameter information in the storage location PCED to the musical tone forming section 2.
It is configured to transfer to 0. In this case, instead of storing all the storage locations of all sets of voice parameter information to be combined with the performance parameter information in the storage part MVMN,
The configuration is such that only the storage location number VMN of the newest specified voice parameter information is stored.

For this reason, switches SW ₁ to _{SW 32}
When new voice parameter information is read by turning on the memory location PCED, the memory location number VMN stored in the memory portion MVMN in the memory location PCED is updated in step 309.

In this way, in steps 303 to 309, the memory location corresponding to the ON operation of switches SW ₁ to _{SW 32} is
Voice parameter information reading or writing processing for VMEM1 to VMEM32 is executed.

When such processing is completed, the compare switch is turned on in step 310 shown in FIG. 7b.
It is determined whether SW _cn has been turned on, and if it has not been turned on, the voice memory processing routine is ended and the next performance memory processing routine is started.

However, if the compare switch SW _cn is turned on, the most recently set voice parameter information and the previously set voice parameter information are alternately displayed in steps 311 to 317 each time the compare switch SW _cn is operated. The voice parameter information is then transferred to the musical tone forming section 20, and a process is executed to alternately form musical tones corresponding to the two voice parameter information and to compare the differences between the two.

That is, in order to change the voice parameter information previously stored in any of the storage locations VMEM1 to VMEM32, after specifying the storage location using the switches _SW1 to _SW32 , the third panel operation section 4 is changed. If you perform an operation to newly set or change voice parameter information using the controls RV ₇ to _{RV 14} , and then turn on the compare switch SW _cn , each time you turn on the compare switch SW cn, the switch SW ₁ to
A process is executed in which the previous voice parameter information designated by SW ₃₂ and the newly set voice parameter information are alternately transferred to the storage location VCED. In other words, for example, in order to change the voice parameter information stored in storage location VMEM1,
When SW ₁ is turned on, steps 303~
Through the process of 309, the previously stored voice parameter information is read from the storage location VMEM1 and transferred to the storage location VCED. After this, control RV ₇
When new voice parameter information is set by ~RV ₁₄ , the new parameter information is stored in the storage location VCED in the voice parameter setting detection process 600 of FIG. After that, when the compare switch SW _cn is turned on, the central processing unit 10
0, the content of the compare flag CMP・F is determined in step 311 of FIG. 7b, and "CMP・F=0" is determined.
If so, in the next step 312 the memory location is
After saving the new voice parameter information stored in VCED to the storage location VCEDB, the storage location
Transfer the previous voice parameter information stored in VMEM1 to storage location VCED. In this case, the storage location VMEM1 of the old voice parameter information to be transferred to the storage location VCED turns on the switch SW ₁ in the storage portion MVMN in the storage location PCED that stores the performance parameter information through the process of step 309. It is memorized immediately afterwards. Therefore, the central processing unit 100 refers to the memory location number VMN stored in this memory portion MVMN, reads out the old voice parameter information from the memory location VMEM1, and reads the old voice parameter information from the memory location VCED.
Transfer to. After this, in step 313, the conveyor flag CMP.F is changed to "1", and then the light emitting diode LED of the compare switch SW _cn is turned on.

When such processing is completed, performance memory processing (step 400) to parameter sending processing (step 700) are executed successively, and in the parameter sending processing (step 800), the old voice parameter information stored in the memory location VCED is transferred to the musical tone. Transfer to the forming section 20.

After this, when the compare switch SW _cn is operated for the second time, the compare flag CMP・F has been updated to "1" in step 313, so the process branches to step 315 based on the judgment in step 311.
Here, the new voice parameter information saved in the memory location VCEDB is saved to the memory location VCEDB.
to be restored. After this, in step 316, after changing the compare flag CMP・F to "0",
In step 317, the light emitting diode LED of the compare switch SW _cn is turned off.

When such processing is completed, performance memory processing (step 400) to parameter transfer processing (step 700) are executed successively, and in parameter transmission processing (step 800) new voice parameter information in the memory location VCED is transferred to the tone forming section 20. Transfer to.

After this, when the compare switch SW _cn is operated for the third time, the same processing as in the first time is executed.

Therefore, each time the compare switch SW _cn is turned on, old voice parameter information and new voice parameter information are alternately transferred to the musical 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 performance memory processing shown in FIG. 8 is executed.

That is, in step 401, it is determined whether or not the character switch SW _ch is on, and if it is on, the switches SW ₁ to SW ₃₂ and SW _p1 to _{SW p8} are used for inputting alphanumeric characters or numbers. Figure 9a
Jump to performance parameter setting detection processing (step 500).

However, if the character switch SW _ch is in the off state, the process advances to the next step 402 and the switch is turned off.
It is determined whether any of SW _p1 to SW _p8 has been turned on, and if it has been turned on, the process proceeds to step 403.
In steps 407 to 407, performance parameter information is read or written. That is,
When the switches SW _p1 to SW _p8 are turned on, performance parameter information is read or written to the storage locations PMEM1 to PMEM8 designated by the switches SW _p1 to SW _p8 . However, if none of the switches SW _p1 to _{SW p8} are turned on, the performance parameter setting detection process (step 500) shown in FIG.
Hejump.

In the processing of steps 403 to 407, first step
Switch SW _p1 turned on in 403 ~
After lighting the light emitting diode LED of SW _p8 , it is determined in step 404 whether or not the store switch SW _ps is turned on. When it is detected through this discrimination process that the store switch SW _ps is turned on, the process proceeds to step 405, and the contents of the memory location PCED are transferred to the memory locations PMEM1 to PMEM8 specified by the switches SW _p1 to _{SW p8} . Write.

That is, for example, when the switch SW _p1 is turned on and the store switch SW _ps is turned on, the performance parameter information that is the content of the storage location PCED is written to the storage location PMEM1 corresponding to the switch SW _p1 .

However, if one of the switches SW _p1 to SW _p8 is turned on, but the store switch SW _ps is not turned on, the process branches from step 404 to step 406, and the process branches to step 406 when one of the switches SW _p1 to SW _p8 is turned on. Specified storage location PMEM1~
Performance parameter information is read from one of the PMEMs 8 and transferred to storage location PCED for storage.

That is, performance parameter information is read from the storage locations PMEM1 to PMEM8 designated by the switches SW _p1 to SW _p8 .

After this, in the next step 407, the memory location is
Refer to the storage location number VMN of the voice parameter information stored in the storage part MVMN in PCED, and store the storage location corresponding to this storage location number VMN.
Read voice parameter information from one of VMEM1-VMEM32 and write it to storage location VCED. Through such processing, the desired performance parameter information specified by the switches SW _p1 to SW _p8 is written to the memory location PCED, and at the same time, the desired performance parameter information specified by the switches SW p1 to SW p8 is written to the memory location VCED for use in combination with the performance parameter information at this time. Voice parameter information is written.

The performance parameter information and voice parameter information written to 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. 9a and 9b is executed.

This performance parameter setting detection process can be broadly divided into the first part, which selects a parameter name using switches SW _n1 to SW _n8 , and displays it on the display device LCD; and a second part that detects parameter information.

FIG. 9a 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 SW _n1 to _{SW n8} has been turned on. As a result of this determination, for example, if it is found that the switch SW _n1 has been turned on, the process proceeds to step 509, a first mode parameter name display process. Similarly, switch SW _n2 ~ _{SW n8}
Steps 510, 516, etc. according to the on operation of
The process advances to the eighth mode of parameter name display processing. Then, each of these parameter display processing (step
509 to 516), the parameter names assigned in advance are displayed on the liquid crystal display device LCD.

In this case, each parameter display process in steps 509 to 516 is configured to be able to sequentially display multiple parameter names, and these parameter names are changed depending on the number of times the same switch is turned on among switches SW _n1 to _{SW n8} . Displayed selectively.

That is, for the switch SW _n1 that displays the parameter name of the first mode,
As shown in the figure, display parameter names are assigned to selectively display transposition information, tone name information, and performance memory information. Also, the second
Switch to display mode parameter names
For SW _n2 , as shown in Figure 11 a-g,
Seven display parameter names are assigned to selectively display pitch bender range information, pitch bender step information, key touch sensitivity information, brilliance information, modulation wheel control information, foot switch control information, and key touch control information. It is being

Furthermore, for the switch SW _n3 that displays the parameter name of the third mode, LFO waveform selection information, LFO phase control information, and LFO pitch modulation information can be selectively displayed as shown in Figures 12a to 12c. Three display parameter names are assigned so that they can be displayed. Also, for the switch SW _n4 that displays the parameter name of the 4th mode, the 1st
As shown in FIG. 3, display parameter names are assigned to display sound effect selection information. Similarly, a plurality of display parameter names are assigned to the switches SW _n5 to SW _n8 that display the parameter names of the fifth to eighth modes. Note that the display parameter names assigned to the switches SW _n5 to SW _n8 and their explanations will be omitted.

The process of selectively displaying a plurality of parameter names 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 job flag M in the first mode is
1 Add “+1” to the contents of JOB・F and update the contents of flag M1 JOB・F,
Job flag for other modes M2 JOB・F～M
3 Clear the contents of JOB・F. This results in
When switch SW _n1 is turned on once, the first
The contents of the job flag M1 JOB.F of the mode change from "0" to "1", while the contents of the job flags M2 JOB.F to M8 JOB.F of the other modes all become "0". And switch SW _n1
When the ON operation is performed 2, 3, and 4 times in succession, job flag M1 is set each time the ON operation is performed.
The contents of JOB・F are updated sequentially as "2", "3", and "4".

When the job flag update process like this is completed,
In the next step 5091, it is determined whether the first mode job flag M1 JOB.F is "4". In other words, the display parameter name assigned to the parameter name display process in the first mode is
There are three, as shown in Figures 10a-c. Therefore, if switch SW _n1 is operated 4 times,
In order to return the display contents of the display device LCD to the initial state, the job flag M1 of the first mode is set.
It is determined whether the content of JOB・F is "4" or not.

In the initial state, 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, if the content of the job flag M1 JOB.F is one of "1" to "3", the process advances to step 5094. Then, it is determined which of "1" to "3" the content of the job flag M1 JOB.F corresponds to, and the processing in steps 5095 to 5097 is selected according to the result of this determination. As a result, if step 5095 is selected, the transposition information parameter name as shown in FIG. 10a will be displayed on the display device LCD.
If step 5095 is selected, parameter names of tone name information as shown in FIG. 10b are displayed. Similarly, when step 5097 is selected, the parameter names of performance memo information as shown in FIG. 10c are displayed.

However, as a result of the determination in step 5091, if the content of job flag M1 JOB・F is "4",
At step 5092, the flag M1 JOB・F
After setting the content to "0", the process proceeds to step 5093, where the display in mode 0, that is, the display content in the initial state as shown in FIG. 14 is displayed.

Through such processing, each parameter name of transposition information, tone name information, and performance memory information is selectively displayed depending on the number of times the switch SW _n1 is turned on.

Similarly, when the switches SW _n2 to SW _n8 are turned on, previously assigned parameter names (FIGS. 11 to 13) are selectively displayed.

When the display of the desired parameter name is completed through such processing, the cursor display is moved up and down or left and right in step 517. That is, when the switches SW _c1 to SW _c4 are operated to specify the display position of parameter information set using numbers or letters, the cursor display is moved in accordance with the operating state of the switch. In addition, in FIGS. 10 to 14, the cursor display is indicated by the symbol CS.

Next, in step 518, the first mode to the eighth mode are selected.
Mode job flag M1 JOB・F~M8
It is determined whether the contents of JOB・F are all "0" or not, and if they are "0", it is assumed that no operation for setting parameter information has been performed, and step 600 in the main routine of FIG. Move on to processing.

However, if some parameter name is displayed by operating switches SW _n1 to _{SW n8} , this means that an operation is being performed to set parameter information corresponding to the displayed content. , the steps of the flowchart shown in Figure 9b.
Proceed to 519.

In the flowchart of FIG. 9b, first, in step 519, it is determined whether or not the character switch SW _ch is turned on. As a result, when the character switch SW _ch is turned on, the parameter information corresponding to the parameter name displayed on the display device LCD is set by switches SW ₁ to SW ₃₂ and SW _p1 to _{SW p8} . The step
At 520, 521..., the contents of the job flags M1 JOB.F to M8 JOB.F of the first to eighth modes are checked to determine which mode the operation for setting parameter information is being performed.

As a result of this determination, the first mode job flag M
1 If the content of JOB・F is not “0”, the first
Since the parameter information for the mode is about to be set, the process advances from step 520 to step 527, where switches SW ₁ to
Detects ON operation of SW ₃₂ and SW _p1 to SW _p8 ,
The alphanumeric or alphanumeric parameter information corresponding to the ON operation of these switches is stored in working memory 1.
It is stored in a predetermined storage part at storage location PCED in 02.

Such processing is performed using the job flag M of each mode.
2 JOB・F~M8 The content of JOB・F is “0”
Even if not, steps 528 to 534 corresponding to each job flag are executed in the same way.

However, the display device LCD does not display the images shown in Figs.
If one of the parameter names shown in the figure is displayed, but the character switch SW _ch has not been turned on, it is checked in step 525 whether or not the character switch SW _ch has been in the off state for 10 seconds or more. Discern. As a result, switch SW _ch
If the off state continues for 10 seconds or more, it is assumed that the operation to set the parameter information has been interrupted or completed, and the contents of all job flags M1 JOB・F to M8 JOB・F are cleared in the next step 526. Thereafter, the display content on the display device LCD is returned to the display content in mode 0 (the display content in 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 SW _ch 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 main routine steps shown in Figure 6 are continued. Proceed to 600.
In other words, if the character switch SW _ch is turned on repeatedly at intervals of less than 10 seconds, the switch
The parameter names selected by SW _n1 to SW _n8 are displayed consecutively. Therefore, while this selected parameter name is displayed, switch SW ₁ ~
When parameter information is set using numbers or letters using SW ₃₂ and SW _p1 to SW _p8 , the parameter information is stored in the storage location PCED in any one of steps 527 to 534.

The processing of steps 527-534 is shown in detail only for step 527. In the process of step 527, the job flag M is first set in step 5270.
1 Determine whether the content of JOB・F corresponds to "1", "2", or "3". As a result, “M1
JOB・F=1”, proceed to step 5271 and press the switch SW ₁ to input numbers and alphabetic characters.
It is determined whether any of SW ₃₂ , SW _p1 to SW _p8 has been turned on. As a result, switch SW ₁ ~
If any one of SW ₃₂ , SW _p1 to _{SW p8} is turned on, in step 5272, 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 as transposition information in the storage portion MPP ₁ in the storage location PCED, and then the process advances to step 600 of the main routine of FIG.

Such processing is performed using job flag M1.

In this way, in the parameter setting section 10,
Since a common display device and information setting switch are used for multiple sets of performance parameter information, the panel operation section can be extremely simplified even when there is a wide variety of performance parameter information to be set. can. Next, the configuration and operation of the tone forming section 20 will be explained.

In the musical tone forming section 20 of FIG. 4, 200 is a keyboard circuit equipped with key switches corresponding to each key of the keyboard 1, and 201 is a keyboard circuit that detects an operated key switch in the keyboard circuit 200 and outputs a key code KC representing the operated key switch. A key press detection circuit 202 assigns the sound of the musical tone corresponding to the key code KC to one of a plurality of sound generation channels (in this case, 8 channels), and performs the sound at the time-sharing channel timing corresponding to the assigned channel. While outputting the key code KC,
A sound generation assignment circuit 203 outputs a key-on signal KON for controlling sound generation, and a sound generation assignment circuit 203 stores the key code KC assigned to each sound generation channel at a storage location in the working memory 102 of the parameter setting section 10.

Frequency information corresponding to the pitch of the key indicated by the key code KCa
This is a portamento control circuit that changes Fa to frequency information Fb that provides a portamento effect or a glissando effect and outputs it. In this case, the speed of the portamento effect is stored in the working memory 10 in response to the operation amount of the operator RV ₆ of the second panel operation section 3 as one of the real-time parameter information.

Controlled by waveform selection information WSD. moreover,
The synchronization relationship is controlled by LFO phase control information PCD set as one of the performance parameter information.

206 is a pitch modulation control circuit that modulates the frequency information Fb of each sound generation channel and outputs it as frequency information Fc. In this case, the frequency information Fb is the modulation wheel of the first panel operation section 2.
Real-time parameter information corresponding to the amount of operation of the MDW, real-time parameter information corresponding to the on/off of the foot switch of the foot switch circuit 103, and real-time parameter information corresponding to the output signal of the key touch sensor 104 are sent from the storage location RTMEM in the working memory 102. However, whether the modulation operation is performed based on each of these real-time parameter information depends on the modulation wheel control information, foot switch control information, and key touch control information set as performance parameter information. Directed by information. Furthermore, the frequency information Fb is also modulated by the output signals of the low frequency oscillators LFO ₁ to _{LFO 8} of the corresponding sound generation channel, but the modulation depth by this low frequency oscillation signal is set as one of the performance parameter information. LFO pitch modulation range information PMRD and the controls on the second panel control section 3

Reference numeral 207 indicates voice parameter information using the frequency information Fc output from the pitch modulation control circuit 206, the key-on signal KON output from the sound generation assignment circuit 202, and the operators RV ₇ to RV ₁₄ of the third panel operation section 4. Envelope control information that controls the attack time _, etc. of the envelope waveform set as
This is a tone generator that forms musical tone signals of pressed keys assigned to each sound generation channel based on volume control information and brilliance information set by RV ₂ . This tone generator 207 is

It is composed of a musical tone forming circuit using a frequency modulation calculation method or the like. In this case, the brightness of the musical tone is basically controlled by the brilliance information set by the controller RV ₂ as one of the real-time parameter information, but the degree of control is controlled as one of the performance parameter information. Controlled by set brilliance control range information. The brightness of the musical tone is determined by real-time parameter information corresponding to the operation amount of the modulation wheel MDW, real-time parameter information corresponding to the on/off of the foot switch circuit 103, and real-time parameter information corresponding to the output signal of the key touch sensor 104. It is also controlled by parameter information. However, whether or not to perform control based on each of these real-time parameter information is instructed by modulation wheel control information, foot switch control information, and key touch control information set as performance parameter information.

The tone and amplitude of the tone signals of each sound channel formed based on this information are further controlled by envelope waveforms generated and controlled by the corresponding key-on signals KON. In this case, parameters such as attack time of the envelope waveform are controlled by the envelope control information described above.

Reference numeral 208 denotes an amplitude control circuit that controls the amplitude of the musical tone signal of each sound generation channel formed by the tone generator 207 and causes the sound system 209 to generate a musical tone. In this case, the amplitude of the musical tone signal of each sound generation channel is set by the low frequency oscillation signal of the low frequency oscillators LFO ₁ to LFO ₈ corresponding to each sound generation channel and the operator RV ₅ of the second operation panel 3. In addition to this, real-time parameter information corresponding to the amount of operation of the modulation wheel MDW and real-time parameters corresponding to the on/off of the foot switch circuit 103 are basically controlled by amplitude modulation depth information. It is also controlled by real-time parameter information corresponding to the output signal of the key touch sensor 104.

In this case, the central processing unit 100 repeatedly performs the real-time parameter setting detection process (step 700) as shown in the main routine of FIG. When there is a change, real-time parameter information corresponding to the latest operator state is transferred to the tone forming section 20. Also, switch SW ₁ ~
If a new storage location for voice parameter information is specified by SW ₃₂ , or if a switch
When a new storage location of performance parameter information is designated by SW _p1 to SW _p8 , the voice parameter information or performance parameter information at the new storage location is transferred to the tone forming section 20.

While the latest real-time parameter information, voice parameter information, and performance parameter information is being sent in this way,
When a key press operation is performed on the keyboard 1, the key press detection circuit 201 sends out a key code KC corresponding to each pressed key in a time-division manner. Then, the sound generation assignment circuit 202 assigns the key code KC corresponding to each pressed key to one of the eight sound generation channels in the tone generator 207,
The signal is supplied to the transposition control circuit 203 in synchronization with the channel time corresponding to each sound generation channel.

Then, the transposition control circuit 203
is the key code assigned to each pronunciation channel.
KC is changed by transposition information TRP. As a result, the key code KC of each sound generation channel is converted into a key code KCa of a range one octave above or below at most, and is supplied to the portamento control circuit 204. Then, the portamento control circuit 204 outputs the sound effect selection information POL/GRS.
When the portamento effect is selected by The output frequency information Fb is changed stepwise at a speed corresponding to the portamento speed control information PSCD until it matches the frequency information Fa corresponding to the new key code KCa. In addition, when the glitsand effect is selected, the frequency information corresponding to the key code KCa′ before receiving the key code KCa is added in the same way as the portamento effect.
Fa' is set as an initial value, and the output frequency information Fb is smoothly changed and outputted at a speed corresponding to the speed control information PSCD until this initial value matches the frequency information Fa corresponding to the new key code KCa.

When the pitch modulation control circuit 206 receives the frequency information Fb that changes stepwise or smoothly from the portamento control circuit 204, the pitch modulation control circuit 206 transmits this frequency information Fb to the low frequency oscillator of the corresponding sounding channel.
It is modulated by the output signals of LFO ₁ to LFO ₈ , and further modulated by real-time parameter information related to pitch modulation, such as pitch bend information corresponding to the amount of operation of the pitch bender wheel PBW, and performance parameter information. It is supplied to the tone generator 206 as information Fc.

As a result, the tone generator 206 receives frequency information Fc, real-time parameter information,
A musical tone signal corresponding to voice parameter information and parameter information for controlling the timbre, amplitude, etc. of a musical tone set as performance parameter information is formed in each sound generation channel.

Then, the amplitude control circuit 208 modulates and controls the amplitude of the musical tone signal formed in each sound generation channel of the tone generator 207 by the output signals of the corresponding low frequency oscillators LFO ₁ to _{LFO 8} , and also controls the amplitude control related to the amplitude control. The real-time parameter information and performance parameter information are further controlled and supplied to the sound system 209.

As a result, the sound system 209 corresponds to the pressed key and corresponds to various parameter information set on the first to fourth panel operation units 2 to 5 or various parameter information read from the working memory 102. A musical tone with the same pitch, timbre, and volume is produced.

It should be noted that since all of the circuit parts constituting the musical tone forming section 20 are well known, a detailed explanation of the circuit configuration thereof will be omitted.

Further, although the parameter information is set using a push button switch, it is also possible to assign numbers or alphabetic characters to each key of the keyboard 1 and set the parameter information by operating each key. In this case, the panel operation section can be further simplified.

Furthermore, the voice parameter information is set by a sliding volume, and the position of the operator is automatically moved by an electric drive mechanism based on the voice parameter information read from the memory. It may be configured as shown in FIG. 15.
