Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parameter setting device for setting and editing a large number of parameter information for forming musical sounds in electronic musical instruments.

[0002]

2. Description of the Related Art In recent years, the tone generator system and peripheral functions of electronic musical instruments have become extremely sophisticated and multifunctional, and various musical tones can be formed. Along with this, the number of parameters that control the operation of electronic musical instruments has become extremely large. For example, in the so-called analog synthesizer that used VCO or VCF in the past, the number of parameters was at most about 20 to 30, but in recent digital synthesizers, even if only the sound source part has 100 to 200 parameters, Including peripheral systems, some have more than 500 parameters.

[0003]

The parameter setting / editing function for the user to input or change such a huge number of parameters is considerably complicated even if, for example, a multi-character display or a graphic display is used. Inevitably. That is, even if such a parameter setting / editing function is provided, the user cannot remember all of the parameters because the number of parameters is huge, and the parameter setting / editing operation is also complicated. There was a problem that I could not master it. Therefore, the user rarely sets and edits the parameter by himself to make a sound, and the actual condition is to select from a combination of parameters preset by the electronic musical instrument maker and use it. That is, although electronic musical instruments such as synthesizers of recent years are provided with a parameter setting / editing function, they have not been used in practice, and have been the nominal parameter setting / editing function.

In view of the above-mentioned problems in the conventional example, the present invention is a parameter setting device used for an electronic musical instrument having a large number of parameters inside, and can be easily operated in accordance with the user's request or the degree of understanding and proficiency. The purpose is to enable effective input and modification of parameters.

[0005]

In order to achieve this object, the present invention is a parameter setting device for an electronic musical instrument, the operation of which is controlled by a large number of parameters, and a memory for storing the large number of parameters. Means, edit level designating means for designating an edit level representing a range of parameters that can be set and edited by the user among the plurality of parameters, operation means for setting and editing the value of the parameter, and the operation Parameter edit means for selectively setting and editing only parameters within a range corresponding to the edit level designated by the edit level designating means among the values of the parameters stored in the storage means, based on the operation of the means. It is characterized by

A plurality of edit levels can be designated by the edit level designating means. For example, the first
The edit level of is for setting and editing only parameters in a very limited range, the second edit level is for setting and editing parameters of a wider range than the range of the first edit level, and the third edit level is for It is advisable to specify multiple edit levels such that all parameters are subject to setting and editing.

When setting and editing only parameters within a predetermined limited range, the parameters other than the target may be left as they are without changing. On the contrary, depending on the status of the setting edit of the parameter that is the setting edit target,
The parameters other than the target may be automatically changed.

Further, a large number of parameters are divided into groups according to the meanings and roles of the parameters, and the group is specified by, for example, a name conceptually representing the group (referred to as a replacement parameter). West,
By changing the setting of one replacement parameter, the setting of each parameter belonging to the group may be changed. For example, with regard to the attack strength of a musical sound wave type envelope, there are cases where the attack strength is internally determined by one parameter, and the attack strength is determined by a plurality of parameters. In some cases, the envelope has a shape as shown. Therefore, regardless of the shape of the envelope, one replacement parameter "attack strength" is used to represent one or more parameters related to the attack strength, and the replacement parameter "attack strength" is represented. May be changed automatically by changing the number of internal parameters.

In addition, while the parameter setting and editing are being performed, the parameter value at that time is held,
You should be able to change the edit level.
As a result, the parameter setting and editing can be performed while changing the edit level, and the parameter setting and editing work becomes easier.

The variable width of the parameter, that is, the range of values that the parameter can take may be different according to the edit level. As a result, it is possible to prevent the nuances of the original timbre from being significantly changed due to, for example, user parameter changes.

[0011]

According to the edit level designated by the edit level designating means, the range of parameters that can be set and edited is determined. Therefore, it is possible to set a range of parameters that can be set and edited in advance according to the user's request or the level of understanding and proficiency, and to provide an edit level for specifying the range. The user can easily and effectively set and edit parameters by designating an appropriate editing level according to his or her own demands or the level of understanding and proficiency.

FM sound source 11 is C
Under the control of PU1, it receives a tone color parameter and a tone generation instruction signal sent out on the bus line 13, and generates a tone waveform signal (digital signal). The digital-analog converter (DAC) 12 is a converter that converts a digital tone waveform signal sent from the FM sound source 11 into an analog signal. The output of the DAC 12 (analog tone waveform signal) is output to a sound system (not shown), whereby actual sound emission is performed.

FIG. 2 shows a panel appearance of the electronic musical instrument of this embodiment. On the panel 20, in addition to the liquid crystal display device (LCD) 21 corresponding to the display 4 described above, various switches and controllers corresponding to the panel switch and the panel controller 6 are provided.

By depressing the play switch 22, the electronic musical instrument enters the play mode. When the user operates (plays) the keyboard in the play mode, a musical sound corresponding to the operation is generated. The tone color of the musical tone is a tone color according to the tone color parameter currently set in the tone color memory 10. In the play mode, the LED 42 provided at the upper left of the play switch 22 is lit to indicate that the current mode is the play mode.

By depressing the edit switch 23, the electronic musical instrument enters the edit mode. In the edit mode, the user can edit (input or change) the tone color parameters stored in the tone color memory 10. In the edit mode, the LED 43 provided at the upper left of the edit switch 23 is turned on to indicate that the current mode is the edit mode.

The tone color number selection switch 31 is composed of ten switches in which the numbers "1" to "10" are engraved. When any one of the switches is pressed, the tone color parameter of the tone color assigned to that switch is read from the ROM 2 and set in the tone color memory 10, and the LED 51 provided at the upper left of the switch lights up and is currently selected. Tones that are The tone color number selection switch 31 may be pressed in either the play mode or the edit mode. In the play mode, a musical tone is generated with a tone color according to the tone color parameter newly set in the tone color memory 10.
In the edit mode, the timbre parameter newly set in the timbre memory 10 is the target of parameter setting editing.

Switch 2 marked with "Level 1"
Reference numeral 4 is a first edit level selection switch. When the switch 24 is pressed in the edit mode, the edit level becomes the first edit level. At the first edit level, the upper left LED 44 lights up. "L
The switch 25 marked with "evel2" is the second edit level selection switch. When the switch 25 is pressed in the edit mode, the edit level becomes the second edit level. At the second edit level, the upper left LED 45 lights up. The switch 26 marked with “Level 3” is the third edit level selection switch. Switch 2 in edit mode
When 6 is pressed, the edit level becomes the third edit level. LED4 on the upper left when the third edit level

When the edit switch 23 is pressed to enter the edit mode, the name of the editable parameter corresponding to the edit level at that time is displayed on the LCD 21. Editable parameter name is LCD21
If it cannot be displayed on one screen, it is displayed on multiple screens. The screen switching is performed by pressing the screen switching switch 27. A cursor is displayed on the screen of the LCD 21. The cursor can be moved on the screen by pressing the cursor key 28. The parameter where the cursor is positioned becomes the parameter for setting editing.

The decrement switch 29 is a switch for decrementing (-1) the value of the parameter to be edited. The increment switch 30 is a switch for incrementing (+1) the value of the parameter to be edited. The data slider 32 is a controller for increasing or decreasing the value of the parameter to be edited.

The basic procedure for editing the tone color parameters is as follows:
First, one of the tone color number selection switches 31 is pressed to read the tone color parameters into the tone color memory 10. At the third edit level described later, the tone color memory 10 may be cleared by an appropriate method to start from a blank sheet. Next, the edit switch 23 is pressed to enter the edit mode, and the edit level selection switch 2
Select any of the edit levels by pressing any of the switches 4, 25, and 26. As a result, the name of the editable parameter is displayed on the LCD 21. The user uses the cursor key 28 to move the cursor to the parameter name to be edited and operates the decrement switch 29, the increment switch 30, or the data slider 32 to set and edit the parameter value. After setting and editing the desired parameters, it becomes possible to perform with the new tone color set in the play mode.

Next, three edit levels that can be designated in this embodiment will be described. The edit level is a level that specifies the range of timbre parameters that the user can edit. 1st edit level (Level
1) is an edit level for beginners, and the range of timbre parameters that the user can edit is very limited. The names of the parameters that the user can edit at the first edit level are not the system parameter names as they are, but some of them are replaced with names that are intuitively understandable to the user (or names that represent the nuances of the timbre). Parameter change range (changeable width)
It is limited to the extent that the original tone is not damaged.

The following six parameters can be set and edited by the user at the first edit level. ATTACK: a parameter indicating the attack feeling of the sound. DECAY: This is a parameter indicating the length of the sound in the decay (decay) part. RELEASE: This is a parameter indicating the release time. BRIGHTNESS: A parameter indicating the brightness of sound (increase / decrease in the amount of harmonics). LFO SPEED: This is a parameter indicating the speed of LFO. PITCHBEND RANGE: a parameter indicating the maximum change range of the pitch bend.

Among the above parameters are LFO SPEE
Some of them are internal system parameters themselves, such as D and PITCHBEND RANGE, and some of them change predetermined internal parameters of the system after performing predetermined processing according to the parameter changing processing by the user. For example, the parameter A representing the attack feeling of the above sound
TTACK may increase or decrease one internal parameter by increasing or decreasing its value, or may increase or decrease multiple internal parameters associated with an attack. How many internal parameters are changed depends on the shape of the currently selected envelope.

FIG. 3 (a) is an example showing parameters related to the envelope which can be set and edited by the apparatus of this embodiment. The envelope in this figure constitutes an attack portion in a section from the level L0 to the rising level L1 at the time of key-on with a slope of the rate R1. Then level L
The decay section is configured to fall from 1 to the rate L2 at the rate R2 and further fall to the level L3 at the rate R2 from the level L2, and the sustain section is configured to maintain the level L3 until the key-off, and from the key-off to the rate R4. The release section is composed of a section that falls to level L4.

On the other hand, there are various other envelope waveforms. For example, even if only the attack portion is taken, the attack portion is formed in the section from the level L0 to the rising level L1 with the slope of the rate R1 as shown in FIG. 3B, and the level as shown in FIG. The attack portion is configured in a section from L0 to the rising level L1 with the inclination of the rate R1 and further from the level L1 to the rising level L2 with the inclination of the rate R2, or FIG.
As shown in (d), the slope rises from the level L0 to the rate R1 to reach the level L1 and further from the level L1 to the rate R2.
There is a configuration in which the attack portion is configured in a section from the rising level L2 with the inclination of 1 to the rising level L3 with the inclination of the rate R3 from the level L2.

Therefore, the tone color parameters currently read in the tone color memory 10 are as shown in FIG. 3 (b) and FIG. 3 (c).
Alternatively, depending on which type of envelope shown in FIG. 3D is a parameter, the way of changing according to the parameter ATTACK operated by the user changes. In the first edit level of this embodiment, for example, when the user increments the parameter ATTACK, the rate R1 is incremented in the case of the type shown in FIG. 3B, and the rate R is obtained in the case of the type shown in FIG. 3C.
1 and R2 are incremented, and in the case of the type shown in FIG. 3D, the rates R1, R2 and R3 are incremented.

At the first edit level, there are no parameters that cannot be set without understanding the FM synthesis method. Generally, there are only parameters that represent the nuances of a sound. At the first edit level, data after parameter edit is not allowed to be stored in memory. Only a temporary change. It should be noted that the first edit level is effective not only for beginners but also for advanced players and the like when changing parameters during playing (not making sounds). For example, it can be used when it is desired to subtly change the nuances of preset tone colors in accordance with the musical tone during performance.

The second edit level is an edit level for intermediate users, and is a edit level for users who have some knowledge of the structure of the synthesizer and want to set and edit other than the parameters that can be set and edited at the first edit level. is there. However, as with the first edit level, the second edit level does not create a sound from a blank state, but merely changes the preset timbre according to one's preference. Therefore, the parameters related to the system configuration of the sound source are not subject to setting editing. The following 14 parameters can be edited by the user in the second edit level.

ATTACK, DECAY, RELEA
SE, BRIGHTNESS, LFOSPEED, PI
TCHBEND RANGE: Same as the first edit level above. VEROCITY: This parameter represents the sensitivity of changing the timbre by key touch. -DETUNE: A parameter indicating the degree to which a detune feeling is given to the sound.・ LFO DELAY, VIBRATO DEPTH,
TREMOLO DEPTH, TRANSPOSE, V
OICE NAME: Each directly modifies internal parameters.

At the second edit level, it is permitted to store the data after the parameter setting and editing in the RAM 3. The tone color name after the store can be changed to distinguish it from the tone color before the store, and the tone color parameter can be read out to the tone color memory 10 with the changed tone color name.

The third edit level is an edit level for a user who is fully familiar with the sound source principle of the synthesizer and the function of each parameter. All parameters can be changed within the maximum change range of the parameter. Since the number of parameters is large, the operation for selecting parameters is complicated, but conversely, precise editing is possible. You can finely recreate the preset tones, or you can create a completely new tone from a blank sheet. This edit level is the same as the parameter edit state that is usually performed in a conventional synthesizer or the like.

The edit level can be changed during the setting and editing of the parameters. For example, even a user at the third edit level can perform AT with a simple operation.
When it is desired to change TACK or DECAY, the level is switched from the third edit level to the first edit level, these changes are made, and the third edit level is restored again. The timbre parameters in the timbre memory 10 are not reset by changing the edit level during parameter setting and editing, and the timbre parameters continue to hold the values at that time. In this way, the edit levels can be moved to each other even while a certain timbre is being edited.

Next, the parameter change width table RTABLE and the limit table LTABLE used in the apparatus of this embodiment will be described. In the apparatus of this embodiment, the parameter that can be set and edited has a predetermined changeable width. That is, each parameter has an upper limit and a lower limit. The upper and lower limits of each of these parameters change depending on the edit level. For example, the first
At the edit level, the parameter change width is set narrow so as not to change the nuances of the original timbre, and conversely, at the third edit level, the parameter can be changed with the maximum change width allowed by the system. .. The parameter change width table RTABLE and the limit table LTABLE are tables used when determining such a parameter change width.

FIG. 4A shows a parameter change width table RTABLE. Parameter change width table RTA
BLE is provided on the ROM 2. RTABLE1
Is a table used at the first edit level. OFFSET11 indicates the changeable width of the parameter p1. That is, the current value of the parameter p1 is a
In this case, the range of the parameter p1 that is changed by the user's operation is limited to a-OFFSET11 ≦ p1 ≦ a + OFFSET11. Similarly, OFFSET12 shows the change width regarding the parameter p2.

RTABLE2 is a table used when the second edit level is set.
.. OFFSET 22, ... Also show the changeable range regarding each parameter, as in the above OFFSET 11.

RTABLE3 is a table used at the third edit level. Table RTABL
The data MAX and MIN in E3 are each parameter p
The maximum and minimum values that can be taken by 1, p2, ... (The maximum and minimum values that can be systematically taken) are shown. These maximum and minimum values are absolute values, not variable widths.

FIG. 4B shows the limit table LTAB.
Indicates LE. Limit table LTABLE is RAM3
It is provided above. In the limit table LTABLE, the maximum value and the minimum value (absolute value) of the possible range of each parameter according to the edit level at that time are set.

Next, referring to the flowchart of FIG.
Edit level selection switch 2 in edit mode
The operation when any one of the switches 4, 25 and 26 is pressed will be described.

Referring to FIG. 5A, when the first edit level selection switch 24 is depressed, step S1
In step 1, the parameter change width table RTABLE1 of the first edit level is referred to, and the maximum and minimum values of all parameters permitted to be edited in the first edit level are obtained. The calculation formula for the calculation is as follows. Maximum value = current parameter value + OFFABLE of RTABLE1
T value minimum value = current parameter value−OFFABLE of RTABLE1
T value

Next, the maximum value calculated in step S12 and the MA in the table RTABLE3 of the relevant parameter.
When the maximum value is larger than the MAX value by comparing with the X value, the maximum value is set to the same value as the MAX value. This is a process of correcting when the maximum value calculated by the above formula exceeds the range allowed by the system. Similarly, the calculated minimum value is compared with the MIN value in the table RTABLE3 of the parameter, and the minimum value is MI.
When it is smaller than N value, the minimum value is
Same value as the value.

Next, in step S13, the maximum value and the minimum value are written in the limit table LTABLE, and the process is terminated. The above processing is performed for all the parameters whose setting and editing are permitted at the first edit level.

Referring to FIG. 5B, when the second edit level selection switch 25 is depressed, the above-mentioned FIG.
The same processing as in (a) is performed. However, RTABL
RTABLE2 is referenced instead of E1.

Referring to FIG. 5C, when the third edit level selection switch 26 is depressed, step S3
In 1, the contents of the table RTABLE3 are copied to the limit table LTABLE, and the processing is ended.

Next, referring to the flowchart of FIG.
The user selects the first edit level as the edit level, and further the parameter AT indicating the attack feeling of the sound.
Select TACK as the edit target, and decrement switch 29 or increment switch 30 (IN in the figure
The operation when pressing (C / DEC SW) will be described.

First, when the decrement switch 29 or the increment switch 30 is pressed in step S41, "1" is set in the work register OP in step S42. The work register OP is a register for setting an operator number (taking a value of "1" to "6") that specifies six operators. Next, step S
At 43, the levels L1, L2, and L3 among the parameters for specifying the envelope are referenced, the maximum level is searched for, and the segment number is set in the register SN.

In this embodiment, the attack portion of any one of the types shown in FIG. 3 (b), FIG. 3 (c) or FIG. 3 (d) is used. Therefore, the levels L1 and L
It is possible to identify which type of attack part the envelope identified by the parameter currently set in the tone color memory 10 has by determining which level of 2 and L3 is the highest. The segment number is a number that identifies each section that transitions between the levels L1, L2, and L3. In step S43, specifically, FIG.
In the attack part of type (b), the segment number SN = 1 because the level L1 is maximum, and in the attack part of FIG. 3 (c), the level L2 is maximum, the segment number SN = 2 and segment number SN = 2. In the attack part of type), the level L3 is the maximum, so the segment number SN = 3
Each will be set.

Next, in step S44, the work register X
Is set to "1" and the work register X is compared with the segment number SN in step S45. If the work register X is the segment number SN or less, step S
At 46, the rate RX of the segment of the segment number X in the operator of the operator number OP is incremented (when the increment switch 30 is pressed) or decremented (when the decrement switch 29 is pressed).

Next, in step S47, the maximum value and the minimum value relating to the rate RX in the limit table LTABLE are read, and it is judged whether or not the rate RX is between the maximum value and the minimum value. Limit to match the maximum or minimum value. Then, the work register X is incremented in step S48, and it is determined whether or not the work register X is "4" in step S49. When the work register X is "4", the rates R1 and R have already been set.
Since the processes of 2 and R3 have been completed, the process proceeds to step S50. If the work register X is not "4", the process returns to step S45 to process the next segment. If the work register X is not equal to or less than the segment number SN in step S45, the process proceeds to step S50.

In step S50, the operator number OP is incremented, and in step S51 it is determined whether the operator number OP is "7". If the operator number OP is not "7", the process returns to step S43 to perform the process for the next operator. When the operator number OP is "7", this means that the processing has been completed for all operators, so the processing ends.

Next, referring to the flowchart of FIG.
The operation when the user selects the first edit level as the edit level, further selects the parameter DECAY as the edit target, and presses the decrement switch 29 or the increment switch 30 will be described.

First, when the decrement switch 29 or the increment switch 30 is pressed in step S61, the operator number OP is set to "1" in step S62.
Set. Next, in step S63, the levels L1, L2, and L3 of the parameters that specify the envelope are referenced, the maximum level is searched for, and the segment number is set in the register SN. In this embodiment, the rates included in the decay section are R2 and R3 for the attack section of the type shown in FIG. 3B, and the rates included in the decay section for the attack section of the type shown in FIG. 3C. Is R3,
In the case of the attack portion of the type shown in FIG. 3D, the envelope included in the decay portion is such that there is no rate.

Next, in step S64, the segment number S
It is determined whether N is "3". When the segment number SN is "3", there is no rate included in the decay portion as described above, and therefore the process proceeds to step S69. When the segment number SN is not "3", the sum of the segment number SN and "1" is set in the work register X in step S65, and the rate RX of the segment of the segment number X is incremented (increment switch 30 by step S66). (When pressed) or decremented (when the decrement switch 29 is pressed).

Next, in step S67, the maximum value and the minimum value relating to the rate RX in the limit table LTABLE are read, and it is judged whether or not the rate RX is between the maximum value and the minimum value. Limit to match the maximum or minimum value. Then, the work register X is incremented in a step S68, and it is determined whether or not the work register X is "4" in a step S69. If the work register X is "4", it means that the processing up to the rate R3 has already been completed, so step S70.
Proceed to. If the work register X is not "4", the process returns to step S66 to process the next segment.

In step S70, the operator number OP is incremented, and in step S71 it is determined whether the operator number OP is "7". If the operator number OP is not "7", the process returns to step S63 to perform the process for the next operator. When the operator number OP is "7", this means that the processing has been completed for all operators, so the processing ends.

Next, referring to the flowchart of FIG.
The user selects the first edit level as the edit level, and further the parameter REL indicating the release time.
The operation when EASE is selected as the edit target and the decrement switch 29 or the increment switch 30 is pressed will be described.

First, when the decrement switch 29 or the increment switch 30 is pressed in step S81, the operator number OP is set to "1" in step S82.
Set. Next, in step S83, the operator number OP rate R4 (R4 is always the release rate) is incremented (increment switch 3).
0 is pressed) or decrement (when the decrement switch 29 is pressed). Next, step S
At 84, the maximum value and the minimum value relating to the rate R4 in the limit table LTABLE are read, and it is determined whether or not the rate R4 is between the maximum value and the minimum value. If the rate R4 is outside the range, it is adjusted to the maximum value or the minimum value. To limit.

Then, in step S85, the operator number OP is incremented, and in step S86, it is determined whether or not the operator number OP is "7". If the operator number OP is not "7", the process returns to step S83 to perform the process for the next operator. When the operator number OP is "7", this means that the processing has been completed for all operators, so the processing ends.

Next, referring to the flowchart of FIG.
The user selects the first edit level as the edit level, and further the parameter BRIG indicating the brightness of the sound.
The operation when HTNESS is selected as the editing target and the decrement switch 29 or the increment switch 30 is pressed will be described.

First, when the decrement switch 29 or the increment switch 30 is pressed in step S91, the operator number OP is set to "1" in step S92.
Set. Next, in step S93, it is determined whether the operator with the operator number OP is a carrier operator. If it is not a carrier operator, it does not affect the brightness of the sound, so the process proceeds to step S96 to proceed to the process of the next operator.

When the operator of the operator number OP is the carrier operator in step S93, the output level of the operator is incremented (when the increment switch 30 is pressed) or decremented (when the decrement switch 29 is pressed) in step S94. To do. Next, in step S95, the maximum value and the minimum value regarding the output level in the limit table LTABLE are read, and it is determined whether or not the output level resulting from the increment or decrement is between the maximum value and the minimum value. If the value is out of the range, limit the value so that it matches the maximum or minimum value.

Then, in step S96, the operator number OP is incremented, and in step S97 it is determined whether or not the operator number OP is "7". If the operator number OP is not "7", the process returns to step S93 to perform the process for the next operator. When the operator number OP is "7", this means that the processing has been completed for all operators, so the processing ends.

It should be noted that the user selects the first edit level as the edit level and sets the parameter LFO S
The process when PEED or PITCHBEND RANGE is selected is the same as the process described above. Also, when the user selects the second edit level as the edit level and selects each of the above-mentioned parameters, the maximum and minimum values of the parameters are different, and the processing is the same as that described above. It is the same.

Next, referring to the flowchart of FIG. 10, when the user selects the second edit level as the edit level, further selects the parameter VEROCITY as the editing target, and depresses the decrement switch 29 or the increment switch 30. The operation will be described.

First, when the decrement switch 29 or the increment switch 30 is pressed in step S101, "1" is set in the operator number OP in step S102. Next, in step S103, the operator parameter VEROCI of the operator number OP
TY is incremented (when the increment switch 30 is pressed) or decremented (when the decrement switch 29 is pressed).

Next, in step S104, the maximum and minimum values relating to VEROCITY in the limit table LTABLE are read, and it is determined whether or not the VEROCITY as a result of incrementing or decrementing is between the maximum value and the minimum value, and the range When outside, limit to match the maximum or minimum value.

Then, in step S105, the operator number OP is incremented, and in step S106 it is determined whether or not the operator number OP is "7". If the operator number OP is not "7", the process returns to step S103 to perform the process for the next operator. When the operator number OP is "7", this means that the processing has been completed for all operators, so the processing ends.

Next, referring to the flowchart of FIG. 11, when the user selects the second edit level as the edit level, further selects the parameter DETUNE as the edit target, and depresses the decrement switch 29 or the increment switch 30. The operation will be described.

First, when the decrement switch 29 or the increment switch 30 is pressed in step S111, "1" is set in the operator number OP in step S112. Next, in step S113, it is determined whether the operator number OP is an even number. If the operator number OP is an even number, the parameter DET of the operator of the operator number OP is obtained in step S114.
Increment UNE (increment switch 30
Is pressed) or decremented (when the decrement switch 29 is pressed), and the process proceeds to step S116. On the other hand, when the operator number OP is an odd number in step S113, the parameter DETUNE of the operator of the operator number OP is decremented in step S115 (when the increment switch 30 is pressed).
Alternatively, the value is incremented (when the decrement switch 29 is pressed), and the process proceeds to step S116.

Next, in step S116, the maximum and minimum values relating to DETUNE in the limit table LTABLE are read, and it is determined whether or not the DETUNE resulting from the increment or decrement is between the maximum and minimum values, and the range is set. When outside, limit to match the maximum or minimum value.

Then, in step S117, the operator number OP is incremented, and in step S118, it is determined whether or not the operator number OP is "7". If the operator number OP is not "7", the process returns to step S113 to perform the process for the next operator. When the operator number OP is "7", this means that the processing has been completed for all operators, so the processing ends.

Although the specific operation when the user selects the third edit level as the edit level is not specified, the editing process is performed within the range of the maximum and minimum values systematically possible for all parameters. Done.

According to the above-described embodiment, the parameters that can be set and edited are largely limited in the first edit level, limited to the middle level in the second edit level, and all the parameters can be edited in the third edit level. .. Therefore, a beginner to an advanced user can select an edit level according to the level of understanding and proficiency of the user, and can easily input and change the parameters with easy operations. If the parameter setting editing is performed at the higher edit level starting from the lower edit level, the user can finally understand all the parameters without resistance.

At the first and second edit levels, for example, the parameter ATTACK represents an internal parameter relating to the attack feeling of the sound.
Even when editing envelopes having different attack parts, it is only necessary to change one parameter ATTACK in operation. Therefore, the operation is very easy for beginners (or even advanced users).

Further, since the parameter changeable width is provided and the parameter can be changed only within the range, for example, in the first edit level, the changeable width should be narrowed so that the original timbre is not damaged. You can also

Next, a second embodiment of the present invention will be described. In the second embodiment, internal parameters are grouped and represented by one replacement parameter, and the replacement parameter is set and edited by the user. The second embodiment has the same configuration as that of the first embodiment and operates in the same manner, so the description of common parts will be omitted. First
In the second embodiment, editing of each parameter is individually performed as shown in FIGS. 6 to 11, but in the second embodiment, FIG.
Handle them uniformly according to the procedure shown in (b).

FIG. 12A shows a parameter group table. Parameter group table is ROM2
It is provided above. The parameter group table is
Multiple parameters p1, p2, p3, ... Inside the system
Is a table showing the correspondence relationships represented by substitution parameters P1, P2, ... In this figure, the four parameters p1 to p4 correspond to the substitution parameter P1, the five parameters p5 to p9 correspond to the substitution parameter P2, and so on. k
1, k2, k3, ... Are parameters p1, p2, p3,
Is the rate of change corresponding to.

The parameter group table is provided for each edit level. At a low level (for beginners) edit level, there are few editable parameters, and more parameters are grouped into one replacement parameter. In a high-order (advanced level) edit level, a larger number of editable parameters and a proper number of parameters are grouped and represented by one substitution parameter.

The operation when the replacement parameter PN is selected and changed as the setting / editing object in the second embodiment will be described with reference to the flowchart of FIG. 12 (b). The operation of selecting and changing the replacement parameter PN to be set and edited is the same as in the first embodiment. That is, in the edit mode, the replacement parameter in the range corresponding to the edit level is displayed on the LCD 21,
Select the replacement parameter by moving the cursor. Then, the decrement switch 29, the increment switch 30, or the data slider 32 is operated to set and edit the value of the replacement parameter.

In FIG. 12B, first, step S1
Substitution parameter P selected for editing in 21
It is determined whether the value of N has been changed. If it has not been changed, the process ends. If it has been changed, then in step S122, information indicating which internal parameters pi to pj correspond to the replacement parameter PN and those internal parameters pi to pj from the parameter group table of FIG. Rate of change ki to kj
Read. Next, each parameter pn is changed using the change width d (predetermined value) and the change rate kn. The calculation formula for the change is pn ← pn + kn.d (where n is i ≦ n ≦ j).

Next, in step S124, the maximum and minimum values for each parameter pn in the limit table LTABLE are read out, and it is determined whether or not the result calculated by the above arithmetic expression is between the maximum and minimum values. If the value is out of the range, limit it to match the maximum or minimum value. Then, in step S125, the final parameter pn (i≤n
≦ j) is written in the tone color memory 10, and the process ends.

When the replacement parameter to be set and edited is displayed on the LCD 21, it is necessary to display the current setting status as a rough guide, which is the weighted average of the parameters belonging to the replacement parameter group. The value obtained by, for example, As a display method, a graph or the like may be used instead of the numerical value. As the weighting coefficient of the weighted average, the change rate kn in the parameter group table of FIG. 12A may be used, or another coefficient may be used.

Further, the above-mentioned change width d is not a predetermined value, and different change width d may be used for each parameter or each replacement parameter. Further, other arithmetic expressions may be used instead of the above arithmetic expressions.

According to the second embodiment, the parameters are grouped and represented by the replacement parameter.
If the replacement parameter is set with a name that is easily understood by the user, the parameter can be easily edited by the user. Also, the processing procedure is simplified.

In the above first and second embodiments,
Although the example in which the present invention is applied to the setting and editing of the tone color parameter has been described, the present invention may be applied to not only the tone color parameter but also other parameters.

Further, any method may be used to determine the range of editable parameters specified at the edit level. For example, in the first embodiment, parameters that can be edited at the first edit level can be edited at the second edit level, and parameters that can be edited at the second edit level can be edited at the third edit level.
Although the example in which the range of parameters that can be edited increases as the edit level increases has been described, the range is not limited to this, and the range may be set such that there are parameters that cannot be edited with each other, for example, the first edit level and the second edit level. You may decide.

Furthermore, in the second embodiment, the combination for grouping is changed for each edit level, and for example, the parameters p1, p2, p at the first edit level.
3, p4 are represented by the substitution parameter P1, while at the second edit level the parameters p2, p3, p4, p5
May be represented by the same substitution parameter P1. Further, the set and edited parameters may be sent to another electronic musical instrument by MIDI or the like.
