DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic sound source device which includes specific tone control data characterizing a tone signal and generates a tone signal based on the specific tone control data between different models. And a method for converting timbre data.

[0002]

2. Description of the Related Art Generally, in an electronic musical instrument, tone control data characterizing a tone set on an operation panel, performance information, and the like are stored in an external storage device such as a floppy disk. make use of,
It can be supplied to other electronic musical instruments. The parameters and performance information include timbres, accompaniment patterns, and the like. The electronic musical instrument to which the musical tone control data and the performance information are supplied generates a musical tone signal based on the information.

By the way, in the above-mentioned electronic musical instrument,
As the musical tone control data, for example, the same correspondence is made between the tone color of the musical tone to be emitted and the tone color number indicating the tone color, and the accompaniment pattern and the accompaniment pattern number indicating the tone color. Therefore, other tone control data between the same models could be used as they were. On the other hand, since the tone control data of other models do not match,
The problem arises that you can't pronounce. For example,
2. Description of the Related Art Conventionally, an electronic musical instrument has been provided with an introductory model, an elementary model, a professional model, and the like according to a level of a player. In these models, the higher the model, the more timbres they have. In other words, the lower-level electronic musical instrument has only some of the timbres of the higher-level electronic musical instrument. Therefore, the musical tone control data created by the upper model electronic musical instrument cannot be used by the lower model electronic musical instrument. That is, since the tone control data of the upper electronic musical instrument includes a tone that the lower electronic musical instrument does not have,
There is a problem that a tone signal cannot be generated based on the tone control data.

Japanese Patent Laid-Open Publication No. Sho 59-197090 proposes a device for converting timbre data created for a high-end model having more timbre functions than low-end models into data suitable for a low-end model. ing. According to this proposal, timbre data is shared between two models, a high-end model and a low-end model. In the low-end model, the actual timbre that can be played for timbre data that cannot be handled is one-to-one. And does not show application to three or more models, diversification of timbre functions, and expansion to an increase in the number of timbre data.

[0005]

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above-mentioned circumstances, and has a novel feature that allows different models to share timbre data for controlling musical sounds and handle them in a unified manner. It is another object of the present invention to provide a useful tone color data conversion method.

[0006]

In order to solve the above-mentioned problems, according to the main feature of the present invention, a plurality of models capable of generating musical tone signals of a plurality of kinds of timbres are provided as defined in claim 1. In the electronic sound source device, when timbre data indicating a tone color of a tone signal to be generated is generated, if the generated tone color data indicates a tone color that can be generated by the model, the tone signal of the tone color is generated. When the generated timbre data indicates a timbre that cannot be generated by the model, the timbre that cannot be generated is replaced with a timbre that can be generated by the model to generate a tone signal. A timbre data conversion method that replaces a plurality of timbres that cannot be generated by the model with the same timbre that can be generated.

In the timbre data conversion method according to the present invention, as described in claim 2, the plurality of types of electronic tone generators are three or more types of electronic tone generators. When replacing the timbre, at least one timbre data may be replaced with a different timbre in the plurality of models.

In the timbre data conversion method according to the present invention, as described in claim 3, the plurality of types of electronic tone generators are three or more types of electronic tone generators. When replacing the timbre, at least one timbre data can be replaced with the same timbre in the plurality of models. A tone data conversion method characterized in that:

[0009]

[0010]

[0011] In the tone color data conversion method configured as any one of claims 1 to 3 by the present invention, as defined in claim 4, further wherein the plurality of types of tone multiple tones If the generated timbre data belongs to any of the series and the generated timbre data indicates a timbre that cannot be generated by the model, the replacement of the timbre can be performed for each timbre series. .

[0012]

[0013]

[0014]

[0015]

According to the main feature of the present invention, in a system for sharing timbre data among a plurality of models of electronic tone generators having different timbre control functions depending on models, a plurality of models that cannot be generated by the model are used. A function of "replacement of a plurality of unproducible tones with the same producible tone" for replacing a tone with the same producible tone is provided. Thus, for example, in a violin-based tone series, when adding a "violin 3" or more "cello" or more as an intermediate model as tone data, and increasing the tone function of the system, in an introductory model, " Both “violin 3” and “cello” can be replaced with “violin 1”.

According to the configuration defined in claim 2 of the present invention, in a new system in which timbre data is shared among three or more types of electronic tone generators having different timbre control functions depending on the types of the models, the "impossible generation" In addition to the function of "replacement of multiple timbres with the same timbre that can be generated", a function of replacing at least one timbre data with different timbres for at least one timbre data when performing timbre replacement for the same timbre data on multiple models has been obtained. Can be As a result, as shown in an example to be described later, when a certain tone data “violin 4” is designated in a violin series tone sequence, when replacing a tone with a plurality of models of an intermediate model and an introductory / elementary model,
The intermediate model model can be replaced with the tone "violin 2", and the beginner / elementary model model can be replaced with another tone "violin 1" different from this.

According to the configuration defined in claim 3 of the present invention, in a new system in which timbre data is shared among three or more models of electronic tone generators having different timbre control functions depending on the models, the "unable to generate" In addition to the function of "replacement of multiple timbres with the same timbre that can be generated", a function of replacing at least one timbre data with the same timbre for at least one timbre data when performing timbre replacement for the same timbre data in multiple models Is obtained. Thus, for example, when certain tone data “violin 3” is specified in a violin-based tone sequence, when replacing with a tone using a plurality of models of beginner / elementary / intermediate models, these models all have the same "Violin 1"

[0019]

[0020]

[0021]

[0022]

According to the configuration defined in claim 4 of the present invention, in addition to the functions according to any one of claims 1 to 3, a new concept of a tone color series is introduced, and a plurality of types of tone colors are introduced. A timbre belongs to any one of a plurality of timbre series, and when timbre data indicates a timbre that cannot be generated by the model, a function of replacing a timbre for each timbre series is obtained. This allows
For example , timbre replacement can be performed for each timbre series such as "violin type" and "strings type".

[0024]

According to the present invention, a new system for sharing timbre data among three or more models can be developed since it has the above-described configuration and operation, and diversification of timbre functions and timbre data can be achieved. It is possible to cope with an increase in the number of the tone generators, to handle unified timbre data, and to reduce confusion when a player uses electronic tone generators of different models.

[0026]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram showing a configuration of an electronic musical instrument according to one embodiment of the present invention. In FIG. 1, a CPU (Central Processing Unit) 1 stores the entire electronic musical instrument shown in FIG. 1 in a ROM (Read Only Memory).
ory) 2 in accordance with a predetermined program stored. Various processing programs described in the present embodiment are also stored in the ROM 2. The CPU 1 stores data and the like obtained when performing various controls in a RAM (Rand
om Access Memory) 3. The RAM 3 is used as a work area for temporarily storing registers, flags, and the like.

The keyboard circuit 4 has a keyboard composed of a plurality of black keys and white keys, and supplies performance information (key-on signal, key-off signal, velocity, etc.) corresponding to the performance to the CPU 1 via a bus. The operation panel 5 includes a switch group including a tone color selection switch 5a, a registration switch 5b, a disk switch 5c, and other switches 5d for setting various parameters in the performance.

The disk device 6 is an external storage device for recording performance parameters set on the operation panel 5 and performance information of the performance. As an external storage device,
For example, a floppy disk is used. Sound source 7
A tone signal (digital) is generated in accordance with performance information and tone information supplied via the bus, and this is supplied to the sound system 8. The sound system 8 converts the musical sound signal into an analog signal and then emits the sound using a speaker.

Referring now to FIG. 2, there is shown a conceptual diagram of registration data between different models. Here, a tone color will be described as an example of registration data. In FIG. 2, in the introductory model (lower model), for example, 25 types of tone color data T
D (1) to TD (25) are provided, and these data are stored in the ROM 2. On the other hand, more data is provided in the upper model, for example, 50 kinds of tone data in the beginner model, 100 kinds in the intermediate model, 200 kinds in the advanced model, and 300 kinds in the bro model. . FIG. 2 shows the tone data TD (1) to TD (300) of the Blo model, but for each of the advanced, intermediate and beginner models,
Omitted.

The same timbre number indicates the same timbre among the models from the introductory model to the blow model. For example, the timbre data TD (1) of the introductory model is different from the timbre data TD (1) of the professional model. It is the same data.
Therefore, the tone color data TD (1) set in the professional model can be pronounced even in the introductory model. However, the timbre data TD (3
00) is timbre data not provided in the introductory model, and cannot be generated by ordinary means. As described above, the number (type) of timbre data provided in the electronic musical instrument is limited to a different number between different models according to the purpose of use of the model.

As areas for storing the registration data, eight registration memories RM (1) to RM (8) are provided regardless of the model. These registration memories RM (1) to RM (8) are assigned to the RAM 3 and each registration memory has registration data (one of them is a tone number indicating tone color data).
Is stored. Registration memories RM (1) to RM (8)
There are the following two cases for storing the registration data in the memory.

First, in the first case, performance information set by the operation panel 5, that is, registration data set on the operation panel 5 of the main body is stored (actually, a panel switch group data memory described later). This is a case in which the performance is performed based on this, or the stored registration data is written into an external storage medium such as a floppy disk by the disk device 6. In this case, the stored resist memory RM (1)
RM (8) are the registration switches 5b shown in FIG.
Selected by.

Next, the second case is a case where registration data stored in an external storage medium is read and stored in these registration memories RM (1) to RM (8). Also in this case, similarly to the first case described above, the stored resist memories RM (1) to RM (RM) are stored.
(8) is selected by the registration switch 5b shown in FIG. Further, a panel switch group data memory PD is provided to store the states of various switches provided in the panel switch group shown in FIG. 1 (hereinafter, referred to as “panel switch data”). A register TSWC for storing the tone number is included.
The panel switch group data memory PD is provided between the above-described resist memories RM (1) to RM (8) and the sound source 7,
It functions as a memory for transmitting and receiving panel switch data as its contents.

Described next is the tone color number conversion table CT according to the present invention. As described above, this tone number conversion table CT is a table for converting tone color data between different models, in this case, between an introductory model, a beginner model, an intermediate model, an advanced model, and a professional model. This is referred to when converting the tone color number of the upper model into the tone color number of the lower model. Therefore, the tone model number conversion table CT is not provided in the bro model which is the highest model. Although not shown, the advanced model, the intermediate model, and the beginner model other than the blow model are provided with a tone color number conversion table CT corresponding to the tone colors of each of them, similarly to the introductory model.

With respect to this tone color number conversion table CT,
The present invention will be described with reference to the conceptual diagram shown in FIG. The timbre number conversion table CT associates the timbre numbers of the timbres of the lower models with the timbre numbers of the timbres of the Blo model, which is the highest model. In this figure, numbers “1” to “300” correspond to tone color numbers TSWC indicating the tone colors of the Blo model. That is,
As shown in the figure, “1” of the tone color number TSWC corresponds to “Strings 1” as the tone color name, and “2” corresponds to “Violin 1”. Hereinafter, similarly, “25” is “contrabass 1”, and “26” is “strings 2”.
"27" becomes "Pizzicato Strings" ...
"299" becomes "Contrabass 3" and "80
“0” corresponds to “contrabass 4”.

The next column shows the tone color number TSWC of each lower model corresponding to the tone color number TSWC (number) of the above-mentioned blow model. As described above, the introductory model has 25 types of tone colors, that is, “1” to “25” as tone color numbers TSWC. Therefore, for this introductory model, the tone number TSWC of the professional model
"1" to "25" of the bro model, "26" of the bro model is "1" of the introductory model, and "50" is "25".
In addition, “51” to “53” correspond to “1”. Then, “54” and “55” of the professional model correspond to “2” of the introductory model. Hereinafter, the tone color numbers after “56” of the professional model also correspond to the tone color numbers of “1” to “25” of the introductory model.

The elementary model has 50 timbres and timbre numbers "1" to "50". Therefore, for this elementary model, "1"
~ The tone number TSWC of "300" is changed to "1"
To “50”. Further, for the intermediate model and the advanced model, similarly, “1” to “3” of the professional model
The timbre number TSWC of “00” is associated with “1” to “100” and “1” to “200” of each model, respectively.

Although the above description has focused on the professional model, the actual tone number conversion table CT is
The tone number TSWC of each model is relatively associated. That is, the tone number TS indicating “strings 1”
The WC "1" is associated with "1 (bro model) -1 (advanced model) -1 (intermediate model) -1 (beginner model) -1 (introductory model)". It is possible to derive a tone number TSWC of a different model. For example, “55” of the tone number TSWC indicating the tone name “cello” is “55 (pro model) −55”.
(Advanced model) -5 (intermediate model) -2 (beginner model)
-2 (introductory model) ".
"5" of the tone color number TSWC of the intermediate model is converted to "2" in the basic model.

FIGS. 4 to 6 are schematic diagrams of a tree structure for explaining three tone color systems. The above-described association method will be described in detail with reference to these drawings. First, the tree structure of the strings system will be described with reference to the Eno-Shi diagram of FIG. This figure shows a tone color number TSWC of each model associated with a string tone color. String-based tones are based on Strings 1, and variations include Strings 2, Strings 3,..., Tremolo Strings, Synth Strings 1,. Each of these strings has an original tone color. For example, strings 6 (tone number TSWC = “201”)
Is the original tone of strings 4 (tone number TSWC = “1
01 ”), and the original timbre of the strings 4 is the strings 2 (tone color number TSWC =“ 26 ”). Further, the original tone color of the strings 2 is the strings 1 (tone color number TSWC = “1”).

In other words, from the strings 2, the strings 4 (tone number TSWC; "101")
Besides the synth strings 1 (tone number TSWC =
"52") and strings 3 (tone number TSWC =
"53") is derived. Furthermore, strings 6 (tone number TSWC = “201”) are derived from strings 4, and synth strings 3 (tone number TSWC = “202”) and synth strings 2 (tone number TSWC = “) are derived from synth strings 1. 102 ")
Is derived. These timbres are derived from the timbres most similar to the timbres, and are associated in the timbre number conversion table CT based on such a tree structure.

From another viewpoint, the introductory model is provided with only one string 1 as strings. On the other hand, in the elementary model, in addition to the strings 1, the strings 2 and the pizzicato strings (tone number TSWCi "27") are provided. Therefore, for example, Strings 1, Strings 2 and Pizzicato Strings in the beginner model are associated with Strings 1, which are their original timbres, in the introductory model. Hereinafter, in a similar manner, correspondence between strings-based timbres is performed between other models based on the tree structure shown in FIG.

Next, FIG. 5 shows a schematic diagram of a violin-based tree structure. In this figure, the violin-based tone is based on violin 1, and variations include violin 2, violin 3,.
There is pizzicato violin solo. And, for these tones, like the strings system described above,
Each of them has an original tone. For example, Kokyu (tone number TSWC = “203”), violin 3 (tone number T
SWC = “104”), violin 2 (tone number TSW)
C = “54”) and the original tone of pizzicato violin solo (tone number TSWC = “106”) is violin 1
(Timbre number TSWC = “2”), and the original tone color of violin 4 (timbre number TSWC = “105”) is violin 2. These timbres are similarly derived from the timbres most similar to the old colors, and are also associated in the above-described timbre number conversion table CT based on such a tree structure.

Here, the relationship between the advanced model and the beginner model will be described. The advanced model has violin 1, violin 3, violin 2, violin 4, cello and 2 ") and pizzicato violin solo as violin-based sounds. In contrast, the elementary model has only violin 1. For this reason, for example, the violin 3 of the advanced model is associated with the violin 1 which is most similar to the tone color. Violin 2 and violin 4 are intermediate models of violin 2
Is associated with violin 1. Similarly,
Cello and pizzicato violin solo are also associated with violin 1. In the same manner, the correspondence between the violin-based timbres is performed between the other models based on the tree structure shown in FIG.

FIG. 6 is a schematic diagram of a contrabass tree structure. In this figure, the contrabass tone is based on the contrabass 1, and the contrabass 2, the contrabass 3,...
…, Pizzicato base, upright base, etc. Each of these tones has an original tone as in the strings and violins described above. For example, contrabass 3 (tone number TSW
C = “299”), contrabass 4 (tone number TSWC)
= “300”), contrabass 2 (tone number TSWC =
"200") and pizzicato bass (tone number TSWC)
The original tone of “= 50”) is the contrabass 1 (tone number TSWC = “25”), and the original tone of the upright base (tone color TSWC = “100”) is pizzicato base. These timbres are similarly derived from the timbres most similar to the old colors, and are also associated in the above-described timbre number conversion table CT based on such a tree structure.

Here, the relationship between the professional model and the advanced model will be described. The pro model includes all of a contrabass 1, a contrabass 3, a contrabass 4, a contrabass 2, a pizzicato bass, and an upright bass as a contrabass tone. On the other hand, the advanced model includes a contrabass 1, a contrabass 2, a pizzicato base, and an upright base. For this reason, for example, the contrabass 1, the contrabass 3 and the contrabass 4 of the bro model are associated with the contrabass 1 which is most similar to the timbre. In addition, Contrabass 2, Pizzicato base and Upright base are
Each is directly associated with the contrabass 2, the pizzicato base and the upright base. Hereinafter, in the same manner, the correspondence between the contrabass-based timbres is performed between the other models based on the tree structure shown in FIG.

The operation of the above configuration will be described with reference to the flowcharts shown in FIGS. The model of the electronic musical instrument described here is an introductory model. First, a procedure for turning on the power to the electronic musical instrument, inserting a floppy disk created by a pro model into the disk device 6, and reading registration data into the registration memory RM will be described. When the power is turned on by the player, the CPU 1
Executes the main routine shown in FIG. Thereafter, the floppy disk is inserted into the disk device 6, and the "Load" switch of the disk switch 5c is pressed.

In the main routine, first, at step SA
In step 1, initialization of various registers and flags is performed. Next, the process proceeds to Step SA2, in which the keyboard is scanned via the keyboard circuit 4, and a process of fetching performance information by detecting key depression, key release, and the like is performed. Next, the process proceeds to Step SA3, and performs a tone color selection switch process shown in FIG. In the tone color selection switch process, first, it is determined whether or not the tone color selection switch 5a has been pressed in step SB1 of FIG. At this time, if the tone color selection switch 5a is pressed, the result of determination in step SB1 is "YE
S "and the process proceeds to Step SB2. In step SB2, the selected tone color number is loaded into the register TSWC. Then, the process proceeds to Step SB3, where the timbre data memory T
After transmitting the contents of D (TSWC) to the sound source 7, the process is terminated and the process returns to the main routine.

On the other hand, if the tone color selection switch 5a is depressed, the result of the determination in step SB1 is "NO", and the process returns to the main routine. In the main routine, the process proceeds to Step SA4. In step SA4, a registration switch process shown in FIG. 10 is performed. In the registration switch process, first, in step SD1 of FIG. 10, it is determined whether or not an event has occurred in the registration switch 5b. In this case, since the registration switch 5b has not been operated, the determination result in step SD1 is "NO", and the process returns to the main routine.

Next, in the main routine, the flow proceeds to Step SA5. In step SA5, the disk control switch processing shown in FIG. 9 is performed. In this disk control switch process, first, in step SC1 of FIG. 9, it is determined whether or not the "Load" switch of the disk switch 5c has been pressed. In this case, as described above, since the “Load” switch has been pressed, the determination result in step SC1 is “YES”, and the process proceeds to step SC2. In step SC2, registration data is read from the floppy disk and written into the registration memories RM (1) to RM (8). Then, when the process of step SC2 ends, the process returns to the main routine. In the main routine, step SA6
Proceed to. In step SA6, after performing other switch processing, the process returns to step SA2 and repeats the above-described steps SA2 to SA6 again.

Next, the performer enters the registration memory RM
In order to perform based on the registration data written in (1) to RM (8), the desired number of the registration memory RM is selected by the registration switch 5b.
The numbers “1”, “2”,... Of the registration switch 5b
When any one of “8” is pressed, step SD in FIG.
The judgment result in step 1 becomes "YES" and the step SD
Proceed to 2. In step SD2, the number of the pressed resist switch 5b is written into the register RSWC.
The process further proceeds to step SD3 to determine whether the "M" switch of the registration switch 5b shown in FIG. 1 has been pressed. In this case, since the “M” switch has not been pressed, the determination result in step SD3 is “NO”.
And proceeds to step SD4.

In step SD4, the contents of the resist memory RM (RSWC), including the contents of the tone color number TSWC, are written to the panel switch group data memory PD. Then, the process proceeds to Step SD5, where data corresponding to the tone color number TSWC in the panel switch group data memory PD is converted using the tone color number conversion table CT.
This is written as a new tone number TSWC. For example, the pizzicato bass corresponding to the tone color number TSWC “50” in the professional model is converted to the contrabass 1 corresponding to the tone color number TSWC “25” in the introductory model.

Then, the flow advances to step SD6 to send the contents of the panel switch group data memory PD to the sound source 7. The tone generator 7 sets a tone color of a musical tone to be generated according to the supplied registration data. Then, the process returns to the main routine. Here, in the main routine, the process proceeds to Step SA6. In step SA6, after performing other switch processing, the process returns to step SA2,
Again, steps SA2 to SA6 described above are repeatedly executed.

Next, a process for storing the states of various switches set on the operation panel 5 by the player in the registration memory RM will be described. When the player presses the "M" switch at the same time as any of the registration switch 5b numbers "1" to "8", step SA4 of the main routine, that is, the registration switch processing shown in FIG. 10 is executed. You.

In this case, the result of determination at step SD1 in FIG. 10 is "YES", and at step SD2, one of the pressed values "1" to "8" is written to the register RSWC. Since the "M" switch is pressed at the same time, the result of the determination in step SD3 is "YES", and the flow proceeds to step SD7. In step SD7, the contents of the panel switch group data memory PD, including the contents of the tone color number TSWC, are stored in the register memory R.
M (RSWC). Then, the process returns to the main routine. In the main routine, the process proceeds to Step SA6. In step SA6, after performing other switch processing, the flow returns to step SA2, and the above-described steps SA2 to SA6 are repeatedly executed again.

Next, the registration memories RM (1) to RM-R containing the registration data transferred as described above are stored.
A process of writing the registration data written in M (8) to a floppy disk will be described. When the player presses the "Save" switch of the disk switch 5c, the disk control switch process of the main routine is executed. In this case, since the “Save” switch has been pressed, the determination result in step SC1 of FIG. 9 is “NO”, and the process proceeds to step SC3.
In step SC3, it is determined whether the “Save” switch has been pressed. The result of the determination at step SC3 is "YES" and the operation proceeds to step SC4.

In step SC4, the contents of the resist memories RM (1) to RM (8) are written to a floppy disk. After that, the process ends, and the process returns to the main routine. In the main routine, step SA6
Proceed to. In step SA6, after performing other switch processing, the flow returns to step SA2, and the above-described steps SA2 to SA6 are repeatedly executed again. The operation described above is not limited to the introductory model, but is similarly performed in the beginner model, the intermediate model, and the advanced model other than the professional model.
On the other hand, in the professional model, only the registration switch processing shown in FIG. 10 is different as shown in FIG.

According to FIG. 11, in step SB1, it is determined whether or not any of the numbers "1" to "8" of the registration switch 5b has been pressed. If none of the registration switches 5b is pressed, the result of the determination in step SE1 is "NO", and the process returns to the main routine. On the other hand, the registration switch 5b
Is pressed, the determination result in step SE1 is "YES", and the flow advances to step SE2. In step SE2, the pressed resist switch 5b is pressed.
Is written into the register RSWC. The process further proceeds to step SE3, where it is determined whether the "M" switch of the registration switch 5b shown in FIG. 1 has been pressed. If the judgment result in step SE3 is "NO",
Proceed to step SE4.

At step SE4, the contents of the resist memory RM (RSWC), including the contents of the tone color number TSWC, are written into the panel switch group data memory PD. Then, the process proceeds to step SE5, where the contents of the panel switch group data memory PD are transmitted to the sound source 7. Sound source 7
Sets the tone color of a musical tone to be generated according to the supplied registration data.

On the other hand, the number "1" of the registration switch 5b
When the "M" switch is pressed at the same time as any one of "8" to "8", the result of the determination in step SE3 is "YES" and the flow proceeds to step SE6. In step SE6, the data including the contents of the tone color number TSWC are written in the panel switch group data memory PD. Then, the process proceeds to a step SD5, wherein the contents of the panel switch group data memory PD are transferred to the resist memory RM (RSWC). After that, the process ends, and the process returns to the main routine. As described above, in the Blo model, the timbre number conversion by the timbre number conversion table CT is not performed.

Next, a second embodiment according to the present invention will be described with reference to FIGS. FIG. 12 shows a schematic diagram of a violin-based tree structure similar to that of FIG. 5, and FIG. 13 shows a series of system data SD in which timbres are associated between the models. In the second embodiment, the correspondence of the timbres between the models, that is, the tree structure itself is the same as in the first embodiment described above, as shown in FIG. However, in this example,
It is characterized in that a series of system data SD of FIG. 13 is written on a floppy disk as a tone number TSWC based on the genealogy obtained from FIG.

That is, the tone color of the violin 1 whose tone color number TSWC is “1” is provided for all models.
Therefore, a series of systematic data SD for violin 1
Becomes “1-1-1-1-1”. Here, each element of the system data SD is sequentially assigned to the tone number TSW of the introductory model, the beginner model, the intermediate model, the advanced model, and the professional model.
C (see FIG. 13). For example, violin 4
(Tone color number TSWC = “4”) is provided only in the professional model and the advanced model. In such a case, tone color numbers TSWC corresponding to the introductory model, the beginner model, and the intermediate model are obtained based on FIG. That is, in this case, the violin 4 corresponding to the violin 4 in the introductory model to the intermediate model is the violin 1 with the timbre number TSWC of “1”. As a result, the system data SD of the violin 4 is “1-1-1-4-4”.

Further, the tone of the violin 3 (tone number T
SWC = “5”) is provided only in the bro model and the advanced model, the intermediate model is provided with the violin 2 having a tone similar to the violin 3, and the introductory model and the beginner model are provided with only the violin 1 Can be Therefore, in this case, the violin 3 corresponds to the violin 2 in the intermediate model, and the violin 1 in the introductory model and the beginner model. As a result, violin 3
Is "1-1-2-5-5". These system data SD are prepared as a table SDT.

In this embodiment, when writing the registration data to the floppy disk, the system data SD is read from the above-mentioned table SDT and written as the tone number TSWC. When reading the registration data from the floppy disk, the system data SD is read, and a predetermined tone color number TSWC is obtained by tracing the system data SD.

When converting a tone number larger than the number of tones stored in the main unit, the tone number is simply converted into the main unit without considering the conversion rule of a tree structure connecting similar tones. May be converted so as to apply to any one of the tones. Further, in the above-described embodiment, the common use of the tone color data has been described. However, the present invention is not limited to the tone color data, but may be various tone control data such as rhythm pattern data, sound effect control data, accompaniment pattern data, and touch data.

Although a conversion table or a series of system data is used for conversion of a tone color number, the present invention is not limited to this, and other means such as an operation and a circuit may be used. In the above-described first and second embodiments, the tone color conversion is performed when the registration switch 5b is pressed. However, the present invention is not limited to this timing. When the registration data is read from the floppy disk, Immediately before the timing at which the sound should be generated.

In the first and second embodiments described above, examples of registration are shown. However, this method is also applied to presets of only tone data and tone data in automatic performance recording data. The automatic performance data may be used for common use in each model. In the first and second embodiments, the example of the floppy disk is shown as the external storage medium. However, the present invention is not limited to this, and a magnetic card, a magnetic tape, a RAM cartridge, a RAM card, an optical recording medium, or the like may be used. You may.

In the above-described first and second embodiments, different models include an introductory model, an elementary model,.
Although a professional model or the like (a model that has a different number of tones but can be represented by a tree structure) was used, but a music genre (a model having a tone that cannot be represented by a tree structure), or a different model with the same control level but different models. Any electronic tone generator having no tone control data may be used.

[Effects of the Invention] As described above, according to the main features of the present invention,
Tone data conversion between two models proposed earlier
No. 9-197090) is completely different from that according to
In a system in which timbre data is shared between multiple models of electronic tone generators with different timbre control functions depending on the model, multiple timbres that cannot be generated by the model are replaced with the same timbre that can be generated. Replacement of multiple tones with the same tone that can be generated. " Therefore, taking a violin-based tone series as an example, the tone color data “violin 3” (tone number “10
4 ")," Cello "(tone number" 5 "
5)), in the introductory model, both "violin 3" and "cello" can be replaced with "violin 1" (tone number "2"). it can.

Further, according to the present invention, in a new system for sharing timbre data among three or more types of electronic tone generators having different timbre control functions depending on the models, the following description is provided. In addition to having a “replacement” function, when replacing a timbre with respect to the same timbre data in a plurality of models, at least one timbre data is replaced with a different timbre in a plurality of models, or at least one timbre data is Multiple models replace the same tone. To give an example of the violin series, the tone data "Violin 4"
If (tone number “105”) is specified, the tone is replaced with the tone “violin 2” (tone number “54”) in the intermediate model, and another tone “violin 1” is different from the introductory / elementary model. "(Tone number" 2 "). In addition, as an example of the latter, if the timbre data “violin 3” (timbre number “104”) is designated, the introduction /
In the models of the beginner / intermediate models, all are replaced with the same timbre "violin 1" (timbre number "2").

According to the present invention, the timbre of the upper model is derived from the timbre of the lower model to one or more among the three or more models, and the timbre data indicates a timbre that cannot be generated by the model. , The timbre replacement is performed according to this derivation relation. For example, to give an example of a string-based tone color series, an elementary model "Pizzicato Strings" (tone number "27") is also an intermediate model, "Pizzicato Strings" (tone number "27").
And the introductory model "Strings 1" (tone number "1") is a beginner model, "Strings 1" (tone number "1"), "Strings 2"
(Tone number "26") and "Pizzicato strings"
(Tone number "27").

According to the present invention, furthermore, a plurality of types of timbres are associated with each model, and replacement of timbres when three or more types The derivation relationship between them is performed retroactively from the upper model to the lower model. For example, in the strings-based timbre series, “strings 1” (tone number “1”) is used for the introductory model, and “strings 2” (timbre number “26”) and “pizzicato strings” (timbre number “ 27)), the intermediate model includes "Tremolo Strings" (tone number "51"), "Synth Strings 1" (tone number "52"), "Strings 3" (tone number "53"), and so on. In addition, the timbre is associated with three or more models. Here, if the own model is a beginner model, "Synth strings 1"
When (timbre number "52") is designated, this "synth string 1" belongs to an intermediate model, so that "strings 2" (timbre number "26") can be obtained by going backward. . If “strings 4” (tone number “104”) is specified, this “strings 4” belongs to the advanced model, so it goes back to the intermediate model. However, since there is no tone corresponding to the intermediate model, By going back further, “strings 2” (tone number “26”) can be obtained.

In the present invention, a new concept of a tone color series is further introduced. When a plurality of types of tone colors belong to any of a plurality of tone color sequences, and the tone color data indicates a tone that cannot be generated by the model, , "Violin type" mentioned above,
The timbre is replaced for each timbre series such as "strings". For example, since the piano timbre is converted to a similar timbre in the same timbre series and is converted to a trumpet timbre of another timbre series, irrelevant timbre data conversion is not performed.
Enables playing with less discomfort.

According to the present invention, among three or more models, the timbres that can be generated by the electronic tone generator of the upper model are completely related to the timbres that can be generated by the electronic tone generator of the lower model. Therefore, the timbres that can be generated by each model can be easily grasped.

As described above, according to the timbre data conversion method of the present invention, the range in which timbre data is shared among three or more models is developed among three or more models, which is completely different from the above-mentioned proposal. Even if the timbre function is diversified and the number of timbre data increases, unified handling of timbre data can be performed, and confusion is reduced when the performer uses different types of electronic tone generators. A great advantage is obtained, for example,
