Abstract

PROBLEM TO BE SOLVED: To easily select a desired tone color from many tone colors by a beginner or a general user by selecting the tone color from the tone color data which are identified based on the data columns that are not deformed and the deformed data columns. SOLUTION: Plural bodies, i.e., tone color numbers are randomly generated. Then, the tone color names corresponding to five generated bodies (tone color numbers), for example, are displayed on a display section 97. Then, the user operates an order specifying switch 96 while looking at the display and orders are assigned to the plural bodies. Then, based on the ordered results, a hereditary operation process is executed. Note that the process is performed in accordance with the operation of a hereditary operation switch and a cross process, a mutation process and a selection process are executed. Then, at a determined cross point, two new tone colors are generated by replacing the identification data of two bodies. Then, a tone color is selected from the identified tone color data based on the deformed data columns or the non-deformed data columns.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tone color selection device for selecting a predetermined tone color from a tone generator device mounted on an electronic musical instrument or the like and a tone color adjustment device for adjusting parameters of the selected tone color.

[0002]

2. Description of the Related Art Recent electronic musical instruments include a large number of tones, and not only beginners but also general users and professionals can understand all the tones incorporated in an electronic musical instrument only by their tone names. It was very difficult to imagine and select a desired timbre. Also, when trying to create a desired timbre by adjusting a timbre parameter, it is necessary to understand how the parameter works for that timbre and to understand the meaning of the parameter itself. It was not possible to create a desired tone color unless one was proficient in specialized knowledge and how to change the tone color by adjustment.

[0003]

Therefore, conventionally, in order to select a desired tone color from a large number of tone colors, the user himself / herself listens to the sound actually pronounced and matches the desired tone color from the image. I had to make a decision as to whether or not to do so, and I spent a great deal of work on the task of selecting a tone color. Further, since a general user usually does not know the meaning of the parameter itself, it has been impossible to directly edit the parameter by himself to adjust the tone color. Even if it can be done, the adjustment work requires a lot of time and labor, and there is no guarantee that the desired tone color will be obtained as a result of the adjustment.
It is an object of the first invention to provide a tone color selection device that enables even a beginner or a general user who does not know the parameters to easily select a desired tone color from a large number of tone colors. It is an object of the second invention to provide a tone color adjusting device capable of easily adjusting a tone color parameter selected from a large number of tone colors over a plurality of sound sources so as to obtain a desired tone color.

[0004]

A tone color selection device according to a first aspect of the present invention is a data string storage means for storing a plurality of tones of tone color data identified based on a data string composed of a plurality of sets of identification data. By supplying a predetermined number of the data strings, and performing arithmetic processing according to a predetermined genetic algorithm on the supplied predetermined number of data strings,
Selection for selecting a tone color from tone color data identified based on the transforming unit that transforms a part or all of the supplied data sequence and the tone color data that is identified based on the data sequence transformed or not transformed by the transforming unit. And means. Since the transforming means transforms the data string by performing arithmetic processing according to a genetic algorithm, it is easy to select a tone that is close to your favorite tone from a much larger number of tones than you can select at random. it can. Further, the user can select and rank the data transformed by the transforming means, and the transforming means will perform the corresponding transformation after that, so that the tone color can be easily brought close to the taste.

A tone color adjusting apparatus according to a second aspect of the present invention stores tone color parameters for a plurality of tone colors, each tone color parameter consisting of a common parameter data string common to a plurality of tone generating methods and a unique parameter data string unique to each tone generating method. A parameter storage means, a predetermined number of the tone color parameters are generated, and among the common parameter data sequence and the unique parameter data sequence forming the predetermined number of generated tone color parameters in the arithmetic processing according to a genetic algorithm. When adjusting the timbre by deforming the common parameter data sequence and the unique parameter data sequence forming the generated tone color parameter by performing at least the crossing process, two tone color parameters to be subjected to the crossing process are selected. When the pronunciation methods are different, the common tone color parameter data And a tone adjusting means for performing the cross-process just about. Electronic musical instruments with multiple tone generation methods have a large number of tone colors, and it is not easy to select the tone color itself.However, if you want to create a new tone color by transforming the selected tone color variously, Due to the difference, it may not be possible to perform arithmetic processing according to the genetic algorithm. Therefore, according to the present invention, when the pronunciation methods are different, at least the crossover processing among the arithmetic processing according to the genetic algorithm is performed only on the common parameter data. It becomes possible to easily adjust the parameters of the selected timbre to obtain a desired timbre.

Next, an example of tone color selection processing executed by the microcomputer will be described with reference to the flowcharts of FIGS. 1 and 3. FIG. 1 is a diagram showing an example of a main routine of a tone color selection process processed by a microcomputer. The tone color selection processing will be described below with reference to FIGS.
A case where a desired tone color is selected from a total of 196 tone colors as shown in FIG. 8 will be described. 6 to 8
Is a tone color list showing 196 tone color names that can be generated by the tone generator circuit 27. Each tone has a GM (General
It is classified into 16 kinds of tone color groups from "1" to "16" corresponding to the MIDI system.
That is, in the tone group, "1" is piano, "2" is chromatic percussion, "3" is organ,
"4" is a guitar, "5" is a bass, "6" is strings, "7" is an ensemble, "8" is a breath, "9" is a lead, "10" is a pipe, "11" is a synthesizer lead, ""12" is a synthesizer pad, "13" is a synthesizer effect, "14" is ethnic, "15".
Is a percussion, and "16" is a sound effect. The numerical data of "1" to "16" here is one of the identification data for identifying the timbre.

Each tone color group is classified into three types of tone generation method groups (PCM method, FM method, physical model method) from "1" to "3". There are a maximum of eight timbres in each pronunciation method group. "1" here ~
The numerical data of "3" is also one of the identification data for identifying the timbre. For example, P with a pronunciation method group of "1"
In the case of the CM system, there are 8 timbres in each timbre group, in the same way that the 128 timbres of the GM system are each classified into 16 timbre groups. In the case of the FM system in which the number of the pronunciation system group is "2", there are 3 types for the piano of the tone group number "1", 5 types for the organ of "3", 2 types for the guitar of "4", and "5". There are three kinds of timbres in the bass, one kind in the ensemble of "7", three kinds in the breath of "8", and one kind in the ethnic of "14", and there is no timbre in the other timbre groups. Number of pronunciation system group is "3"
In the case of the physical model method of, the tone color group number "1"
2 types of piano, 2 types of "2" chromatic percussion, 4 types of "3" organ, 2 types of "4" guitar, 3 types of "5" bass, 6 of "7" ensemble Types, 3 types for "8" breath, 1 type for "9" lead, 1 type for "10" pipe, "11"
There are 5 types of synthesizer leads, 7 types of "12" synthesizer pads, 8 types of "13" synthesizer effects, 2 types of "14" ethnic effects, and 3 types of "15" percussive tones. No tone color exists in the tone color group numbers "6" and "16" other than this. The item numbers from "1" to "8" are assigned to each tone color, and the item number where no tone color exists is "0". Numerical data corresponding to each item number of "1" to "8" here is one of the identification data for identifying the timbre. Therefore,
Each of the timbres in the timbre list of FIGS. 6 to 8 has three identification data of a timbre group number, a sounding method group number and an item number of (1-1-1) or (9-1-2). Will be specified by the data string thus listed, that is, the tone color number. For example, the tone number (data string) is (1
In the case of (1-1), it indicates the tone color group number “1”, the tone generation group number “1”, and the tone number of the item number “1”, that is, the acoustic grand piano.
In the case of 2), it indicates the tone color group number “9”, the tone generation method group number “1”, the item number “2” tone color, and the alto saxophone.

The tone color selection process of FIG. 1 operates so that a desired tone color is selected by variously changing such tone color numbers by a genetic calculation process. First, in step 11, a plurality of individuals, that is, tone color numbers, are randomly generated. For example, five individuals (tone color numbers) are generated. The tone color names corresponding to the generated five individuals (tone color numbers) are displayed on the display unit 97. In step 12, the user operates the order designation switch 96 while looking at the display content of the display unit 97 to rank the plurality of individuals. If the ranking is not performed, the ranking may be performed in the order of occurrence. In step 13, genetic operation processing is executed according to the result ranked in step 12. This genetic operation processing is performed in response to the operation of the genetic operation switch, and three types of processing such as crossing processing, mutation processing, and selection processing as shown in FIG. 3A are performed. The intersection process is a process as shown in FIG.
Any two individuals are randomly selected from the individual). The next step is to randomly determine the intersection. Here, the intersection is the tone color number (1-1-
It is "-" in 1) or (9-1-2). Therefore, here, the first "-" or the second "-" is randomly determined. Then, in the final step, two new timbres are generated by exchanging the identification data of the two individuals at the determined intersection. For example,
It is assumed that the process of step 11 generates five individuals, which are ranked by the process of step 12 as follows. The first is the acoustic grand piano (Acoustic Gran) with tone number (1-1-1).
d Piano), the second tone color number (9-1-2) Alto Sax (Alto Sax), the third tone color number (13-3-4) Nylon Harp (NylnHar)
p) It is assumed that the church organ 1 with the tone color number (3-1-4) is ranked fourth, and the agogo (Agogo) with the tone color number (15-1-2) is ranked fourth. Then, when the tone color numbers (1-1-1) and (9-1-2) are selected as two individuals from these and the intersection is determined to be the first "-", the tone color group number ""1" and "9" are replaced,
Soprano Sax with tone number (9-1-1) and tone number (1-1
-2) Bright Acoustic Piano (Bright
tAcoustic Piano) is generated by the intersection process.

The operation of the next mutation process will be described. The mutation process is a process as shown in FIG. 3C, and any one or a plurality of individuals is randomly selected from a plurality (5) of individuals. In the next step, identification data to be mutated is randomly determined. here,
The identification data is a tone color group number, a sounding method group number, and an item number, which are components of the tone color number.
Therefore, any one of the tone color group number, the sounding method group number and the item number is determined here. Then, in the last step, the value of the determined identification data, that is, any one of the tone color group number, the sounding method group number and the item number is randomly changed. For example, when the tone color number (1-1-1) is selected as one individual and the identification data to be mutated is determined to be the item number, the value "1" of the item number is randomly changed, for example, " 7 ”. Then, the timbre is mutated from the acoustic piano having the timbre number (1-1-1) to the harpsichord having the timbre number (1-1-7).

The following selection process will be described. The selection process is a process as shown in FIG. 3 (D), and the new individual generated by the above-described crossing process and mutation process is replaced with an individual having a lower rank. For example, in the order as described above, a soprano sax with a tone color number (9-1-1) and a bright acoustic piano with a tone color number (1-1-2) (B
It is assumed that a right acoustic piano) is generated and a harpsichord of a tone color number (1-1-7) is generated by the mutation process. In this case, the lower 3 individuals among the above 5 are replaced with these 3 individuals. Therefore, the above-mentioned five individuals are subjected to the tone color number (1
-1-1) acoustic grand piano (Aco
ustic Grand Piano), tone number (9
-1-2) AltoSax, and tone number (9-1-1) Soprano Saxophone (Sopran)
o Sax), tone color number (1-1-2), bright acoustic piano (Bright Acoustic)
c Piano) and timbre number (1-1-7) harpsichord.

In the next step 14, the new tone color name generated as a result of the genetic calculation process is displayed on the display unit 97, and the user moves the cursor with the cursor switches 90 and 91 and operates the audition switch 92 there. By doing so, a sound corresponding to the tone color name where the cursor is located, that is, the tone color number, is generated through the sound system 2A. When the audition switch 92 is operated, the display unit 97
The sounds of the tone color names currently displayed may be played in order. A message is displayed on the display unit 97 as to whether or not there is a favorite tone in the reproduced tones, and an instruction from the user, that is, the Yes switch 98 or No switch 9 is issued by the user.
When the user operates the yes switch 98, the process proceeds to step 16, and when the no switch 99 is operated, the process proceeds to step 15. In step 15, a message as to whether or not to start over is displayed on the display unit 97, and similarly, waiting for an instruction from the user, and when the user operates the yes switch 98, the process returns to step 11 and the same processing is repeated. If the user operates the no switch 99, step 1
Returning to step 2, the timbres generated as a result of the genetic calculation processing are ranked again by the user, and the same processing is repeated thereafter. In step 16, since it is determined that there is a favorite tone color in the previous step 15, any message of that tone color is displayed on the display unit 97, and the user moves the cursor with the cursor switches 90 and 91. Therefore, the tone color name at which the cursor is located, that is, the tone color number at the time when the selection switch 93 is operated, is stored as the tone color finally selected by the user from the 196 types of tone colors.

FIG. 4 is a diagram showing an example of a main routine of a parameter edit process executed by the microcomputer. The parameter edit process will be described below. FIG. 9 is a diagram showing parameters common to each sounding method and parameters unique to each sounding method. There are nine types of parameters common to each pronunciation system, from "1" to "9" as shown in the column of common parameters in FIG. 9, "1" is an effect parameter, and "2" is LF.
O parameter (waveform, speed, depth, etc.), “3” is key scaling related parameter, “4” is velocity sensitivity, curve parameter, “6” is pitch EG parameter, “6” is filter EG parameter,
“7” is an amplitude EG parameter, “8” is a pan parameter, and “9” is a filter-related parameter. Each of these parameters is composed of a plurality of parameter data. For example, the effect parameter “1” is data indicating the type of effect (chorus, reverb, distortion, etc.), data different for each type of this effect, dry / wet data indicating the degree of effect, and send level data. Is composed of four parameter data. The other parameters are similarly composed of a plurality of parameter data. A shared parameter data string is formed by arranging a plurality of parameter data forming these nine types of parameters in order.

There is one type of parameter peculiar to the PCM system, and only the parameter of the waveform of "1". This waveform parameter is composed of a plurality of parameter data such as waveform selection data, frequency mode data, and frequency fine adjustment data. A plurality of parameter data arranged in order becomes a PCM system unique parameter data string.
There are nine types of parameters peculiar to the FM system, from "1" to "9" as shown in the FM column of Fig. 9, "1" is an algorithm form parameter (operator combination format), and "2" is feedback. Parameter (feedback source and feedback destination of operator output), “3”
Is an oscillator related parameter (waveform, frequency, phase, etc.), “4” is an operator amplitude EG parameter,
"5" is an operator pitch EG parameter, "6" is an operator LFO parameter, "7" is an operator input level parameter, "8" is an operator output level parameter, and "9" is an operator sensitivity parameter. These parameters are also composed of a plurality of parameter data strings. These 9
The FM-type unique parameter data string is formed by sequentially arranging the parameter data forming the respective types of parameters. There are eight types of parameters peculiar to the physical model, from "1" to "8" as shown in the physical model column of Fig. 9, and "1" is a pressure parameter (breath pressure of wind instruments, bow speed of stringed instruments). , "2" is an embouchure parameter (the reed biting of a wind instrument, the pressing force of a bow of a stringed instrument), "3" is a tonguing parameter (a tongue playing technique of a wind instrument), and "4" is a breath noise parameter (breath sound). , "5" is throat formant parameter (throat state), "6" is damping parameter (energy loss), "7" is resonator parameter (resonance),
“8” is a growl parameter (timbre, periodic fluctuation of volume). These parameters are also composed of a plurality of parameter data strings. A parameter data string of the physical model method is formed by sequentially arranging parameter data that respectively configures these eight types of parameters. When the parameters of each tone color as described above, that is, the common parameter data string and the unique parameter data string are arranged, the data structure is as shown in FIG. That is, the data structure is such that the unique parameter data string exists after the common parameter data string.

The parameter edit process of FIG. 4 operates so as to create a desired timbre by varying various parameters by the genetic operation process even if the parameters are different for each sounding method. First, in step 31, a plurality of individuals (tone color numbers) are randomly generated, or a user selects a tone color (tone color number) close to his or her preference to extract, for example, five individuals (tone color numbers). A desired tone color may be selected from the 196 types of tone colors shown in FIGS. 6 to 8 by operating a tone color selection switch (not shown) or the tone color selected by the tone color selection process of FIG. Or plural) may be used.
Since the tone color names corresponding to the five extracted individuals (tone color numbers) are displayed on the display unit 97, in step 32, the user operates the order designation switch 96 while watching the display content of the display unit 97, and a plurality of tone color names are displayed. The individuals are ranked. If the ranking is not performed, the ranking may be performed in the order of extraction.

In step 33, genetic operation processing is executed according to the ranked result. This genetic operation processing is performed in response to the operation of the genetic operation switch, and is the same as in the case of the tone color selection processing described above, as shown in FIG.
Three types of processing such as crossover processing, mutation processing, and selection processing are performed as shown in FIG. Here, only the crossover process is different from the above case, and the mutation process and the selection process are shown in FIGS. 3 (C) and 3 (D).
Is the same as Therefore, the crossover process will be described, and the mutation process and the selection process will be omitted. The intersection process in the parameter edit process is a process as shown in FIG. First, in step 41, any two individuals (timbre numbers) are randomly selected from a plurality of (five) individuals, and whether two individuals (timbre numbers) selected in step 42 have the same pronunciation system is checked. If the same sounding method (YES) is determined, the process proceeds to the next step 43. If different sounding method (NO), the process proceeds to step 45. If it is determined in step 42 that they have the same sounding method (YES) (if the two selected individuals (timbre numbers) have the same sounding method as shown in (A) of FIG. 10), all of them are judged in step 43. Within the parameters (the above-mentioned parameter data group), the intersection (dotted line part in FIG. 10) is randomly determined,
In step 44, the parameters of the two individuals are exchanged at the determined intersection within all the parameters. Here, the intersections are alternately replaced. If it is determined in step 42 that the pronunciation is different (NO) (if the two selected individuals (timbre numbers) have different pronunciations as shown in FIG. 10B), common in step 45. Randomly determine the intersection within the parameters,
In step 45, the parameters of the two individuals are exchanged at the intersection determined within the common parameter.

In the case of the tone color selection described above, the number of intersections was two at the maximum, so one of the intersections was determined. However, as in this parameter editing process, common parameters and tone generation methods are selected. When the total number of parameter data constituting the unique parameter is about 40 to 80, the number of intersections is not only 1 but is randomly determined to be 2 or more, and each determined intersection is used as a reference. Then, the parameter group to be replaced is determined. Therefore, at this intersection, a plurality of intersections indicating the replacement positions of both parameters when these parameter groups are arranged in order are determined. Needless to say, the number of intersections may be one.

In the next step 34, the five new tones generated as a result of the genetic calculation processing are displayed on the display section 97, so that the user moves the cursor with the cursor switches 90 and 91, and then presses the audition switch 92. By operating, a sound corresponding to the tone color where the cursor exists is generated through the sound system 2A. It should be noted that, when the audition switch 92 is operated, the tones displayed on the display unit 97 may be reproduced in order. A message is displayed on the display unit 97 as to whether or not the reproduced tone has a desired tone, and the user waits for an instruction from the user, that is, the user operates either the yes switch 98 or the no switch 99. When the yes switch 98 is operated, the operation proceeds to step 36, and when the no switch 99 is operated, the operation proceeds to step 35. In step 35, a message as to whether or not to start over from the beginning is displayed on the display unit 97, and similarly, an instruction from the user is waited for. If the user operates the yes switch 98, step 31
Return to and repeat the same process. User does no switch 9
When 9 is operated, the process returns to step 32, and the timbres generated as a result of the genetic calculation process are again ranked by the user, and the same process is repeated thereafter. In step 36, it is determined that the desired tone color is present in the previous step 35. Therefore, in this case, the message is displayed on the display unit 97 and the user selects the cursor switch 90,
The cursor is moved at 91, and the tone color at which the cursor is located at the time when the selection switch 93 is operated is stored as the tone color finally selected by the user. In addition,
Since there is no existing tone color name in the displayed tone color, the user may freely set the tone color name and then store it.

In the above-mentioned embodiment, the electronic musical instrument has been described as an example, but the present invention is not limited to this, and may be applied to a combination of a personal computer and application software, and is not limited to a keyboard musical instrument. It may be applied to a string instrument type, a wind instrument type, a percussion instrument type, a sound source module type and the like. In the above-described embodiment, the case where the intersection is obtained randomly has been described, but the data string to be subjected to the intersection processing may be randomly selected in advance. The intersection may be designated by the user. In addition, in the mutation process, the case where the identification data to be the target of the mutation process is randomly determined has been described, but it is determined that the identification data that cannot be the target can be randomly selected from the possible targets. You may do it. For example, when mutating any one of the tone color group number, the pronunciation method group number, or the item number, one of them is excluded from the mutation target, and the other one is targeted as the mutation target. You may This is the same in the case of mutation of the parameter data string. In the above-described embodiment, the crossover process, the mutation process, and the selection process are described as the genetic operation process, but it goes without saying that a multiplication process may be performed in addition to this. Further, only one of the crossover process and the mutation process may be performed. In the above-described embodiment, the case where the genetic operation process is performed once and the genetic process is performed again depending on whether or not there is a favorite one has been described. However, after performing the genetic operation process a plurality of times, Alternatively, the process may proceed to the determination of whether or not there is a favorite one. Further, at this time, the genetic calculation process may be repeatedly performed according to the number of times the genetic calculation switch is pressed and the time during which the switch is pressed.
