Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic musical instrument system including an electronic musical instrument capable of controlling generated musical tones according to musical tone control information supplied from the outside.

[0002]

2. Description of the Related Art Conventionally, pitch data or tone color of a musical tone,
In an electronic musical instrument equipped with musical tone generating means for controlling the generation of musical tones based on musical tone control data for controlling effects, pitch data or musical tone control data is supplied from outside the electronic musical instrument, and the electronic musical instrument is supplied. The tone pitch, tone color, effect, etc. of the musical tone generated in the above has been controlled, but the pitch data or tone control data supplied from the outside has been used as it is.

In general, there are various types of such electronic musical instruments, from low-grade models to high-grade models, and the high-grade models have a wider tone range (pitch range) than the low-grade models, and have functions such as tone color and effects. There are usually many. Also, even among models of the same class, the number of functions of tone range, tone color, and effect may differ depending on the specifications. For this reason, pitch data and tone control data are configured for each model in a form suitable for that model. If the pitch data and tone control data of a certain model are used as they are, electronic Often I couldn't control my instrument. In order to eliminate such inconvenience, it is conceivable to limit the pitch data and musical tone control data so that they can be commonly used by different models. Therefore, the functions of the high-end model cannot be fully exerted.

As a general technique for converting the pitch data, there is a technique disclosed in, for example, JP-A-57-96396 or JP-A-53-80218. In Japanese Unexamined Patent Publication No. 57-96396, note information (including pitch information) is expressed and stored in different codes depending on the frequency of use in order to compress the storage capacity of the note information storage device of the automatic performance device. , A technique in which note information (including pitch information) read out at the time of performance is decoded into a predetermined code. JP-A-53-802
In No. 18, in the automatic bass accompaniment, when the pitch of the automatic bass tone is determined by the calculation of the bass pattern data and the root note data, the pitch obtained by the calculation has a predetermined pitch range (for example, the pitch range of the pedal keyboard). ) Is exceeded, data is converted so that it falls within a predetermined range, so that the automatic bass sound does not enter the same range as a melody sound, for example. However, none of these conventional techniques is a technique for dealing with the case where the musical tone control information (especially tone color designation or control information) externally taken into a certain electronic musical instrument cannot be generated by the electronic musical instrument. It is irrelevant, and no solution is given for it.

[0005]

Various types of automatic performance information are typical examples of the musical tone control information that is externally taken into the electronic musical instrument. Since the music to be played has an instrument tone color that matches the musical tone of the song, the automatic performance information usually includes data that specifies the pitch of each tone, as well as the tone code that corresponds to the instrument tone used in the performance. There is. However, in the past, the model level (that is, higher model / lower model)
The number of tone colors that can be produced, the tone color code setting mode, the tone color quality, etc. are different due to the different capabilities of the tone signal generating circuit, so that each electronic musical instrument model has its own tone color code setting. Therefore, it is necessary to separately prepare the automatic performance information for each model such as the upper model / lower model of the electronic musical instrument to which the automatic performance information is applied. As a result, common automatic performance information cannot be used in different types of electronic musical instruments, that is, electronic musical tone generating devices, resulting in poor efficiency.

Therefore, the object of the present invention is to control performance based on the performance information including the tone control information by incorporating the performance information including the tone control information supplied from the outside into an electronic musical instrument, that is, an electronic tone generator. When musical tones are generated, electronic musical instruments of different models, that is, electronic musical tone generators, can use common musical performance information and can efficiently use the musical performance information. To provide a system.

[0007]

An electronic musical instrument system according to the present invention includes at least one electronic musical instrument having a musical tone generating means for generating a musical tone controlled based on given musical tone control information. An electronic musical instrument system in which musical tone control information is externally supplied to the electronic musical instrument by the musical tone generating means in the electronic musical instrument to generate a musical tone controlled based on the supplied musical tone control information. The tone control information supplied from the outside includes tone color information classified into first and second groups, and each tone color information of the first group is supplied from the outside. Is basic tone color information that indicates a musical instrument tone color that can be realized in the electronic musical instrument without being limited to the model of the electronic musical instrument included in the electronic musical instrument system. , A common musical instrument tone color is designated for any type of the electronic musical instrument corresponding to the value of the tone color information, and each tone color information of the second group is included in the electronic musical instrument system. External tone control information supply means, which is advanced tone color information that indicates instrument tone colors that can be realized by a specific model of electronic musical instrument and instrument tone colors that cannot be realized by other models, and the external tone control information. When the tone color information included in the tone control information supplied from the supply means to an electronic musical instrument other than the specific model belongs to the second group, the value of the tone color information can be realized by the electronic musical instrument. The musical instrument tone color is converted into a value indicating the musical instrument tone color, and is provided to the musical tone generating means in the electronic musical instrument.

According to the present invention, the musical tone control information externally given to the electronic musical instrument via the external musical tone control information supplying means includes the tone color information classified into the first and second groups. Each timbre information of one group is basic timbre information that indicates a musical instrument timbre that can be realized in the electronic musical instrument without being limited to a model of the electronic musical instrument included in the electronic musical instrument system, and A common musical instrument tone color is designated for any type of the electronic musical instrument corresponding to the value of the tone color information, and each tone color information of the second group is the electronic musical instrument system included in the electronic musical instrument system. It is characterized by high-level timbre information that indicates instrumental timbres that can be realized by a specific model of musical instrument, and that indicates instrumental timbres that cannot be realized by other models.

As described above, the tone color information included in the tone control information (for example, automatic performance information) given from the outside is classified into the first and second groups, and the tone color information of the first group is the basic tone color. As information, a musical instrument timbre that can be realized by any type of electronic musical instrument in this electronic musical instrument system is designated, and a common musical instrument timbre corresponding to the value of the timbre information is supplied to any type of the electronic musical instrument. However, since the tone color information of the first group can be used as it is in any type of electronic musical instrument included in this electronic musical instrument system,
It is possible to perform a performance (automatic performance) by designating a common instrument tone color for all types of electronic musical instruments. Therefore, there is an excellent effect that a preferable performance (automatic performance) can be performed by any type of electronic musical instrument without impairing the musical composition of the performance music.

On the other hand, the tone color information of the second group is high-level tone color information which indicates instrument tone colors that can be realized by an electronic musical instrument of a specific model. Therefore, when the tone color information of the second group is given. This musical instrument timbre cannot be realized in electronic musical instruments of other models (so-called lower-grade models) other than the specific model (so-called high-grade models). However, according to the present invention, when the tone color information included in the tone control information supplied from the outside to the electronic musical instrument of the other model belongs to the second group, the value of the tone color information is set to the electronic musical instrument. In the electronic musical instrument (so-called low-end model), the tone color of the second group can be obtained by including the converting means for converting the musical instrument tone color that can be realized by It is possible to generate a musical tone of any musical instrument tone color based on the information. Accordingly, for an electronic musical instrument (so-called low-grade model) belonging to the first group and having a function of generating only basic musical instrument tones, a musical tone control including tone color information indicating a higher-grade musical instrument tone belonging to the second group. Even if information is supplied from the outside, the electronic musical instrument (so-called low-end model) can be played (automatically played) without causing troubles such as pronunciation failure.

Therefore, according to the present invention, a basic musical instrument tone color can be secured regardless of the model, and a high-grade musical instrument tone color can be used in a low-grade model which cannot be used originally. By combining with the advantage of performing data conversion in this way, it is not necessary to separately prepare musical tone control information (for example, automatic performance information) supplied from the outside for each electronic musical instrument model, and electronic musical instruments of different models That is, since common externally-supplied musical tone control information (for example, automatic performance information) can be used in the electronic musical tone generator, the musical performance information (externally-supplied musical tone control information) can be efficiently used. That is, it has a unique excellent effect.

For example, by preparing only one type of automatic performance information for a desired song, it is possible to supply it from the outside and use it in common in any type of electronic musical instrument, regardless of whether it is a higher-level model or a lower-level model. With regard to the basic instrument tones belonging to the first group, the musical tone generation control is performed by any electronic musical instrument with the common musical instrument tone color. Therefore, the sound quality of the common musical instrument tone differs depending on the model of each electronic musical instrument. However, at least by the musical tone generation control based on the nominally common musical instrument tone color, it is possible to perform an automatic performance suitable for the musical composition of the musical composition in any type of electronic musical instrument. For example, even if automatic performance information created for a lower model is automatically played by a higher model, it is possible to enjoy automatic performance with a richer sound quality with the same instrument tone color that matches the song. In addition, when an automatic musical performance information supplied from the outside indicates a high-quality musical instrument timbre belonging to the second group, it is automatically used by the electronic musical instrument of a lower-level model that cannot use it. Even if the automatic performance information created for a higher model is used, it can be commonly used for electronic musical instruments of a lower model because the musical tone is replaced by an appropriate timbre that can be produced.

Further, according to the present invention, the tone color information of the first group can be used without any special data conversion (information value conversion) processing in any type of electronic musical instrument, so that the conversion means can be used. In this case, the data conversion (information value conversion) process may be performed only on the tone color information of the second group, and the configuration of the conversion means can be simplified. On the other hand, if the tone color information of the first group is not configured to specify a common musical instrument tone color for any type of electronic musical instrument as in the present invention, that is, Assuming that automatic performance information is created for each electronic musical instrument model as in the past, in order to be able to apply this automatic performance information to electronic musical instruments of other models, all the tone color information The data conversion process must be configured to perform the necessary data conversion for. Therefore, the advantages of the present invention are great. According to this invention, for example, the conversion means extracts a part of a plurality of digital bits constituting the tone color information included in the tone control information supplied from the outside to extract the value of the tone color information. It is a conversion. This can simplify the configuration of the conversion means. In addition,
In the present invention, the musical instrument tone color is, as is generally known,
In electronic musical instruments, it is a conceptual tone color that is distinguished by giving nominal tone color names corresponding to various musical instruments such as a piano and a guitar, and as shown in the examples described later, human voice sounds ( In other words, it can be regarded as a human voice instrument).

DETAILED DESCRIPTION OF THE INVENTION An example of an embodiment of the present invention will be described in detail below with reference to the accompanying drawings. FIG.
Shows an embodiment of an electronic musical instrument system according to the present invention, in which the present invention is applied to an electronic musical instrument having an automatic playing device. The data reading device 10 is for reading performance data relating to a performance music piece from an external recording means composed of any one of a magnetic tape, a punch card, a bar code print body, etc. Data is stored in the data memory 12 which is an access memory in a format as shown in FIG.

In FIG. 2, the performance data is the notes N1 and N.
Note data corresponding to each note includes pitch data PTD indicating the pitch and code length data NLD indicating the note length. The tone color data TCD for initial tone color setting and the effect data EFD for initial effect setting are inserted between the pitch data PTD and the note length data NLD corresponding to the first note N1. For the second and subsequent notes, the tone color data TCD or the effect data E is placed at the note position corresponding to the timing at which the tone color or effect is desired to be changed.
Each FD is inserted. The pitch data PTD,
Tone color data TCD, effect data EFD, and note length data N
A pitch mark Mp, a tone color mark MT, an effect mark ME, and a note length mark MN are added to the LD in order to identify each data.

When a performance start switch (not shown) is turned on, the data reading circuit 14 causes the data memory 12 to generate pitch data PTD and tone color data TC corresponding to the note N1.
D, the effect data EFD, and the code length data NLD are sequentially read. The read pitch data PTD is stored in the pitch register 16
The register 16 in response to the detection of the pitch mark Mp.
The tone color data TCD fetched and read in is loaded into the register 18 in response to the tone color register 18 detecting the tone color mark MT, and the effect register 20 detects the effect mark ME in the read effect data EFD. It is loaded into the register 20 in accordance with.

The read note length data NLD is used in the data read circuit 14 to determine the read timing of the data corresponding to the next note N2. That is, the data reading circuit 14 measures the time corresponding to the code length indicated by the data NLD by counting the tempo clock signal, etc., based on the code length data NLD corresponding to the first note N1, and corresponds to the code length. When the time is reached, the data memory 12
The pitch data PTD and the note length data NLD corresponding to the second note N2 are read. Then, the same data reading operation is performed for the data corresponding to the third and subsequent notes. Further, the contents of the registers 16, 18 and 20 are updated by the corresponding read data in accordance with such data reading.

The first pitch data PTD from the pitch register 16 is converted data P via the pitch data conversion circuit 22.
A key press display circuit 24 and a tone signal forming circuit 2 as TD '
6. The key-depression display circuit 24 includes a large number of display elements 30 provided corresponding to a large number of keys on the keyboard 28.
The display element corresponding to the first note is lit according to the conversion data PTD '. Therefore, the player of the keyboard 28 can easily know the key to be pressed first. It should be noted that such a key depression display operation is similarly performed each time new pitch data PTD is sent from the pitch register 16.

When the tone pitch register 16 sends the first tone data PTD, the tone color register 18 sends the first tone color data TCD and the effect register 20 sends the first effect EFD. The tone color data TCD from the tone color register 18 is supplied to the tone color control data memory 34 as converted data TCD ′ via the tone color data conversion circuit 32. This memory 34 is a ROM that stores tone color control data for each tone color such as piano, flute, and violin.
(Read-only memory), etc., and includes tone color control data TC corresponding to the tone color indicated by the conversion data TCD '.
Is supplied to the tone signal forming circuit 26. Further, the effect data EFD from the effect register 20 is the effect data conversion circuit 3
It is supplied to the musical tone signal forming circuit 26 as conversion data EFD ′ via 6. The tone signal forming circuit 26 uses the conversion data PTD ′ from the pitch data converting circuit 22 and the memory 3
Tone color control data TC from 4 and effect data conversion circuit 3
A musical tone signal is formed on the basis of the converted data EFD 'from 6 and the pitch of this musical tone signal is the converted data PT.
The tone color is determined according to the tone color control data TC, and the effect is determined according to the conversion data EFD ′ according to D ′.

Now, when the pitch data corresponding to the first note N1 is supplied to the tone signal forming circuit 26 as the conversion data PTD ', this circuit 26 is initialized by the tone color control data TC and the conversion data EFD', respectively. A tone signal corresponding to the note N1 is formed so as to show the reproduced tone and effect. Then, the formed musical tone signal is supplied to the speaker 40 via the output amplifier 38 and converted into sound. Therefore, the musical sound corresponding to the note N1 is produced from the speaker 40. Such a musical tone generating operation is similarly performed for the read data corresponding to the second and subsequent notes. When data corresponding to the newly read tone color data is generated as the tone color control data TC, the tone color characteristics of the tone signal forming circuit 26 are changed and controlled accordingly. Further, when data corresponding to the newly read effect data is generated as the conversion data EFD ', the effect characteristic of the tone signal forming circuit 26 is changed and controlled in response to this.

The player can perform a manual performance on the keyboard 28 in accordance with the automatic performance sound generated as described above and, if necessary, with reference to the key depression display. Each key on the keyboard 28 drives a corresponding key switch of the key switch circuit 42.
Reference numeral 2 designates key-depression data representing the depressed key as the tone signal forming circuit 2
Supply to 6. The tone signal forming circuit 26 forms a tone signal corresponding to the key depression indicated by the key depression data from the key switch circuit 42 and supplies it to the speaker 40 via the output amplifier 38. Therefore, the speaker 40 also produces a manual performance sound.

FIG. 3 shows a specific example of the pitch data conversion circuit 22 in the case where the octave of the pedal keyboard (PK) sound is changed. In this case, the range of PK sound is in the range of C2 to C4 for high-end models, and C2 to C4 for low-end models.
It is in the range of C3, and the pitch data PTD is configured according to a high-end model. The pitch data PTD is
It is composed of note code data NC indicating a note name, octave code data OC indicating an octave, and keyboard code data KBC indicating a keyboard name. The octave code data OC consists of a 3-bit binary code of O1 to O3. The octave to which C2 belongs, the octave to which C # 2 to C3 belong, and the octave to which C # 3 to C4 belong are shown in Table 1 below. Code content is defined in.

[0023]

[Table 1]

Since the circuit of FIG. 3 cannot handle the pitch data specifying the octave to which C # 3 to C4 belong in the low-end model as it is, this pitch data is used as the data specifying the octave to which C # 2 to C3 belongs. It is configured to convert. That is, when the PK detection circuit 50 detects the arrival of PK pitch data based on the keyboard code data KBC, it supplies the output signal "1" to the AND gate 52.
At this time, the octave code data O of the PK pitch data
If C designates the octave to which C # 3 to C4 belong and the signals O1 and O2 are "1", the AND gate 52 supplies the output signal "1" to one input terminal of the AND gate 54. To do. In the case of a low-end model, the "1" signal source is connected to the other input terminal of the AND gate 54.
The ND gate 54 supplies the output signal “1” to the inverter 56. The inverter 56 generates an output signal "0" according to the output signal "1" from the AND gate 54 to make the AND gate 58 non-conductive. Therefore, the signal O1 is AND
The gate 58 converts “1” to “0”.

As a result, the PK pitch data designating the octave to which C # 3 to C4 belong is converted into the data PTD 'designating the octave to which C # 2 to C3 belong. Therefore,
As far as the octaves to which C # 3 to C4 belong are concerned, the low-end model will generate a PK sound (bass tone) one octave lower than that of the high-end model. It should be noted that FIG.
If a conversion circuit such as
However, instead of the "1" signal source, a "0" signal source may be connected. By doing so, the AND gate 58 is always in the conductive state, and the octave code data OC is output without being converted.

FIG. 4 shows a specific example of the tone color data conversion circuit 32 in the case of changing the tone color of the upper keyboard (UK) tone. In this case, the timbre of the UK sound is piano, flute, violin, vocal (tenor),
Eight tones of guitar, clarinet, viola and vocal (soprano) can be specified, and only four tones of piano, flute, violin and vocal (tenor) can be specified for low-end models, and tone data TCD is configured according to advanced models. It has been done. The tone color data TCD is U
It is composed of tone color group designation data GC indicating tone color groups corresponding to K, LK (lower keyboard), PK and the like, and tone color designation data CC including 3 bits Q1 to Q3.
The chord content is defined for each tone color as shown in Table 2 below.

[0027]

[Table 2]

The circuit of FIG. 4 is configured to change the tone color data of the B group to the tone color data of the A group because the tone colors of the B group in Table 2 cannot be handled by low-end models. That is, when the UK tone color detection circuit 60 detects the arrival of the UK tone color data based on the tone color group designation data GC, it supplies the output signal “1” to one input terminal of the NAND gate 62. In the case of a low-end model, a "1" signal source is connected to the other input terminal of the NAND gate 62, so that the NAND gate 62 generates an output signal "0" and outputs A signal.
The ND gate 64 is turned off. At this time, if the UK tone color data designates any tone color belonging to the B group of Table 2 and the signal Q3 is "1", this signal Q3 is changed from "1" to "0" by the AND gate 64. ”
Is converted to

As a result, the tone color data designating the tone color of the B group in Table 2 is converted into the data TCD 'designating the tone color of the A group in Table 2. That is, the guitar is changed to piano, the clarinet is changed to flute, the viola is changed to violin, and the vocal (soprano) is changed to vocal (tenor). That is, if the tone color of the B group that cannot be generated by the low-grade electronic musical instrument is a decay tone-type tone (guitar), another tone color of the decay tone system (piano) that can be generated by the low-grade electronic musical instrument is designated. On the other hand, when the tone color of the B group is converted to the data TCD ′ and the tone color of the B group is a continuous tone color tone (clarinet, viola), another tone color of the continuous tone type (flute, violin) that can be generated by the electronic musical instrument of the lower model ) Is converted into data TCD '. When a conversion circuit as shown in FIG. 4 is provided in a high-end model, the “0” signal source may be connected to the NAND gate 62 instead of the “1” signal source.

FIG. 5 shows a concrete example of the effect data conversion circuit 36. The circuit in this example is intended for use in low-end models that only have on / off control functions for the sustain effect and vibrato effect as effect control functions. It is configured to derive only the signal. The effect data EFD is configured according to the high-end model, and includes the sustain control signal SU and the tremolo control signal T.
R, duet control signal DU ... Delay vibrato control signal DVB and vibrato control signal VB are included.
Of these effect control signals, the tremolo control signal TR,
The duet control signal DU ... Delay vibrato control signal DVB is supplied to one input terminal of each of the AND gates AG1, AG2 ... AGn. Where AND gate A
"0" is input to the other input terminal of G1 to AGn for low-end models
Since the signal source is connected, each AND gate is non-conducting. Therefore, the tremolo control signal TR, the duet control signal DU ... the delay vibrato control signal DVB, etc. are A.
The conversion data EF is blocked by the ND gates AG1 to AGn.
As D ', only the sustain control signal SU and the vibrato control signal VB are transmitted. It should be noted that FIG.
If a conversion circuit such as
Instead of the “0” signal source for 1 to AGn, the “1” signal source may be connected.

In the above embodiment, the performance data is read from the external recording means and stored in the RAM.
An exchangeable ROM or other recording medium storing performance data may be provided, and the performance data may be read from this ROM for automatic performance. In this way, the data reading device becomes unnecessary and the RAM replaces the ROM. Further, in the above embodiment, the data conversion circuit may be provided between the data reading device 10 and the tone signal forming circuit 26. For example, the data conversion circuit may be provided between the data reading device 10 and the data memory 12. It is also possible to detect the type (pitch, tone color, effect, etc.) and perform data conversion in the previous stage of the data memory 12.
