Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a performance data expression processing apparatus and a recording medium for performing an expression on a performance data by reflecting an instrument performance such as a guitar performance having a human touch in the performance.

[0002]

2. Description of the Related Art Conventionally, in order to give a musical instrument characteristic sound characteristics to performance data, a user has to search for the position and edit the data so that the characteristic is obtained.
In this case, in order to bring the sound quality closer to the acoustic, it is necessary to sufficiently know the characteristics of the acoustic, and it is necessary to be patient and to take patience.

For example, in a sequencer or the like, when a certain part, mainly a melody part of a guitar, is hit, pitch bend data and the like are added to make it look like guitar hammering. For example, in an expensive band score or the like, the location of the hammering on is written on the score, and while watching this score, pitch bend data is created and pasted or modified to make it look like a guitar hammering. However, such an operation is very troublesome.

[0004] With regard to the slide playing method (bottleneck playing method), if there is a song that is to be modeled, the user must perform the driving while listening to the sample song, but it takes much time and the situation is the same. If there is no song to be modeled, the data of the slide playing style must be added according to the judgment of the player.

[0005] Vibrato requires a great deal of time and effort since vibrato data is created in consideration of where and how much vibrato is required. Also,
In order to express the character of guitar by volume playing technique,
We are working on volumes and the like, but this also requires advanced driving techniques.

Conventionally, in the driving of a guitar part, a mute sound or a mute sound created by processing an EG waveform is added to a portion deemed necessary, so that advanced driving technology is required. Furthermore, with regard to the arpeggio of a guitar, an arpeggio is usually entered to give each musical tone an appropriate pitch and velocity to give an expression.
This method is also very cumbersome and time-consuming.

[0007] In the driving music, there are standard phrases in the solo part of the guitar part such as ad lib, riff, ending and the like, but it is also very troublesome to input such phrases.

[0008]

SUMMARY OF THE INVENTION In view of such circumstances, it is an object of the present invention to easily generate performance data that expresses a natural musical instrument by applying characteristics suitable for a tone color, rather than a simple performance.

An expression processing device for performance data, comprising: a change processing unit for changing to data or a tone characteristic corresponding to a tone characteristic change rule and generating performance data of a predetermined tone color. Further, according to this feature, a step of acquiring performance data, a unit for storing musical tone data or a tone characteristic change rule corresponding to an instrumental playing style corresponding to a predetermined tone color, and a step of specifying a playing style of a musical instrument corresponding to the predetermined tone color. Analyzing the state of a plurality of musical tones constituting the acquired performance data; and storing the musical tone data or musical tone characteristic changing rule according to the musical instrument playing style corresponding to the predetermined timbre. Extracting predetermined music data or music characteristic change rules based on the result obtained; and
Changing the characteristic of the tone of the specific part in the acquired performance data to the extracted tone data or the tone characteristic corresponding to the tone characteristic changing rule, and generating performance data of a predetermined tone color. A recording medium for expression processing of performance data is provided.

In the present invention, the analyzing means analyzes the tone generation state of the tone in the predetermined tone channel and the other tone channels of the acquired performance data, and the change of the tone characteristic by the change processing means is random. It is configured to be executed with gender or a predetermined probability. Further, the predetermined timbre is preferably a guitar timbre.

According to another feature of the present invention, the analyzing means detects a musical tone at a predetermined position in a predetermined section, and the change processing means changes a characteristic of the detected musical tone to a playing style of a musical instrument corresponding to the predetermined tone color. The performance data is changed to a characteristic corresponding to the predetermined tone color and the performance data of the predetermined tone color is generated. Further, the analyzing means analyzes the tempo and the predetermined position in the predetermined section, and the change processing means changes the characteristic of the musical tone at a low position in the predetermined section in the predetermined section according to the playing style of the musical instrument corresponding to the predetermined tone color. It is configured to change to characteristics and generate performance data of a predetermined tone color. The analyzing means analyzes the playing style designating information for the musical tone of the acquired performance data, and the change processing means makes the characteristic of the musical tone having the predetermined playing style designating information a musical tone corresponding to the playing style of the musical instrument corresponding to the predetermined tone color. Change to characteristics,
It is configured to generate performance data of a predetermined tone color.

According to the present invention, a plurality of musical tones constituting performance data are analyzed, and the tempo, key, tone, and position of musical tones (section positions such as intro, adlib, riff, ending, etc., start of playing, Note position of the first note, etc.), the relationship between notes (whether the corresponding playing style has already been applied before and after, tuplet, ascending / descending, etc.), the pronunciation instruction status of the musical tone (arpeggio, etc.) Such as the flow,
Musical instruments corresponding to the specified tone (various guitars, saxophones, etc.) (bottleneck, volume, etc.)
To determine the conditions that should be applied, and, depending on the result, change the characteristics of the pronunciation for each specific musical tone in accordance with the specified playing style, or mute ornament, choking, hammering, and pulling. A characteristic corresponding to a characteristic change rule relating to previously stored musical sound data such as an off-slide or a hammering-on / pulling-off arpeggio is added.

In other words, the tone of the selected pitch is not a tone of the selected tone, but a target to which a sound quality characteristic peculiar to a musical instrument operation that is entered by a human being operating the instrument is automatically added. And an appropriate characteristic is added to this. Therefore, it is possible to more naturally express emotions, environments, and atmospheres, and to generate performance data sufficiently expressed according to the musical instrument playing style.

In the present invention, each tone characteristic to be changed (changed) can be arbitrarily selected by means for designating the playing style of the musical instrument corresponding to the predetermined tone color. In the process of changing the tone characteristics, it is effective to take into account the sounding state of another part (channel) or to execute the process with randomness or a predetermined probability at continuous processing points.

According to the present invention, a particularly remarkable expression effect can be obtained by implementing the predetermined tone color as the guitar tone color. In the performance operation of a guitar, a performance sound other than a unique human-like musical sound may be generated, or a subtle change in the musical sound may occur. This is a performance characteristic of a musical instrument, and the characteristics differ depending on the type of the same guitar. Therefore, in the embodiment described in detail below, a guitar is used, but the present invention can be applied to saxophones and other musical instruments or timbres, and the specific processing method can be changed according to the timbre.

In the present invention, the characteristics to be changed (changed) include the addition of a bottleneck (slide) playing method [simulation /
Pseudo bottleneck playing method), volume [simulation / pseudo volume playing method], addition of separately stored decorative sound data (for example, mute sound), addition of hammering-on / pulling-off, and other accrual ( Characteristics that imitate the habits and feelings of famous players)
(Insertion of a phrase), a characteristic change corresponding to the position of the arpeggio (arpeggio special playing technique), and the addition of a vibrato characteristic that changes subtly when vibrato is gathered (vibrato addition).

This will be described more specifically. If you look at the score and play the score data as it is into a sequencer or the like, the melody will be a mere note-on / off melody. In one embodiment of the present invention, a guitar slide playing method (bottleneck playing method) in a phrase of original performance data.
Detects the sound to which is added. For example, if you want to create an American mood, the sound to which the slide playing technique is added is automatically detected. Then, the detected sound is slid from one sound to one octave from both directions of pitch up / down. Therefore, even if there is no example music, the slide playing technique can be automatically and easily added.

In this case, assuming open tuning (several types), in addition to the original sound, the sound of the adjacent string and other chord constituent sounds can be automatically slid and produced. Also, a mechanical sound at the time of sliding can be added as necessary. For example, an actual rubbing sound generated by rubbing a string at the time of sliding can be sampled, and the mechanical sound can be added to the necessary sound. Add to the location.

In one embodiment of the present invention, a portion deemed necessary in the guitar part struck by the sequencer, for example, the tempo is relatively slow and the intro ad lib.
At the beginning of playing the guitar such as ending, intro,
The drum part is not moving and only the guitar or guitar
Since it is configured to detect parts starting with parts such as keyboard strings, tempo-free parts, etc., and apply EG, volume, amplitude, etc. of the detected parts to volume changes equivalent to volume playing techniques, Even beginners can easily perform guitar expression. It should be noted that a part other than the guitar part can be expressed like a guitar by using this method.

In one embodiment of the present invention, a mute sound is stored in advance, and a portion deemed necessary in a guitar part struck by a sequencer, for example, the tempo is relatively slow and the intro, ad lib, ending , Etc., and the part after the 8th and 16th note tuplets are detected, and the mute sound stored in memory is added to this part as a decorative sound to enhance the existence of the sound. wear. In addition, the configuration is such that the degree of addition can be reduced, so that even a beginner can easily perform guitar expression. It should be noted that a part other than the guitar part can be expressed like a guitar by using this method.

In one embodiment of the present invention, the addition of a guitar hammering technique is used as one of the articulations of a sequencer, and by incorporating this function, any melody phrase of the music is automatically added. The hammering playing style of the guitar is added, and the number of occurrences of hammering can be arbitrarily increased or decreased. Therefore, a phrase as if playing on a guitar can be automatically created.

For example, if the location of the hammering-on is not specified on the score of the guitar part, this function is used to automatically create the performance data with the hammering-on added and make the guitar-like sound heard. be able to. Also, by applying this function to other instrument parts, performance data close to a guitar phrase can be obtained.

In one embodiment of the present invention, a chord, a hammering, a chopping, a hammering, etc. are previously performed by a MIDI guitar or striking corresponding to a standard phrase in a solo part such as an ad lib, a riff, an ending of a guitar part.
Several types of phrase data including articulations such as pull-offs and slides are prepared as MIDI data. Even if these data have different tempos and tones, the sequencer automatically converts them and makes them compatible. Then, when necessary, necessary data is pasted into the calling sequence. This allows for difficult phrase performances.

Since these phrases include the habits and feelings of the player (name player), the process of preparing the phrase data in advance is as follows.
You have to choose a player. In addition, by preparing performance phrases of all other musical instruments such as saxophones as well as guitars, the characteristics of the musical instruments and players can be realized by the sequencer.

In the embodiment of the present invention, the arpeggio of the guitar can be heard more naturally by making the arpeggio rules. In other words, if you have an arpeggio in the guitar part of the driving music,
However, even if you type according to the music, no expression is born,
In the present invention, rules are created as if a human were playing. For example, a predetermined rule is used to automatically give an arpeggio tuplet an optimal tone length and automatically give the velocity of each musical tone.

In one embodiment of the present invention, when there is a lot of vibrato in the vicinity, the vibrato adding process for slightly changing the vibrato is performed without making the vibrato characteristics constant.
In this process, vibrato data is sampled in advance as MIDI data. For example, on a guitar,
Swing the string in a direction parallel to the string (change the tension of the string)
Such delicate vibrato data, vibrato data that shakes a string in a direction perpendicular to the string (particularly choking frequently used in an electric guitar, etc.), and the like are sampled. Then, the sampled vibrato data is automatically added according to the flow of the phrase, the duration, the tempo, the musical composition, and the like. The added vibrato data is configured such that its depth, speed, and the like can be edited according to the user's preference. Therefore, it is possible to add vibrato of a natural expression corresponding to the flow of the phrase, the duration, the tempo, the musical composition, and the like.

Stores a predetermined control program for controlling this system, and these control programs include:
Along with the basic performance information processing, various processing programs, various tables and data relating to the panel setting and processing according to the present invention are included. The RAM 3 is used as a work area for storing data and parameters necessary for these processes, and for temporarily storing various registers and flags, various data being processed, and the like. Therefore, these devices 1 to 3 can read out programs and various set values and process the performance data according to the set items.

The external storage device 4 includes a floppy (registered trademark) disk (FD), a magneto-optical (MO) disk, a smart media, and a compact disk (CD) in addition to a hard disk (HD) built in the system in advance. For example, a storage device using a movable storage medium such as a storage device is used. The HD drive (HDD) is a storage device for storing a control program and various data. When the control program is not stored in the ROM 2, the control program is stored in a hard disk in the HDD, and is stored in the RAM 3. The CPU 1 can cause the CPU 1 to perform the same operation as when the control program is stored in the ROM 2. In addition, CD drive
It is also possible to read out a control program and various data stored in the HDD or the like and store the data in a hard disk in the HDD. Further, since a control program and various data can be stored in a hard disk in the HDD from a server computer or the like through a communication interface (not shown), addition of a control program and version upgrade can be easily performed.

The panel operator device (operation panel) 5 includes a plurality of setting operators for performing various settings for performance data processing. These setting operators are, for example,
These are various switches attached to an operation panel of an electronic musical instrument, various keys of a PC keyboard, a pointing device such as a mouse, and the like, and are called “panel operators”. The performance operator device 6 includes performance operators for designating and inputting tone data. These performance operators include, for example, performance operators such as a keyboard of various electronic musical instruments and P
These are predetermined keys or the like assigned for performance on the C keyboard, and are called "performance operators". The display device 7 controls the display state of a display and various indicators (not shown) connected thereto. In addition, by pointing various buttons on the setting screen and data input screen displayed on the display with a pointing device,
Various settings and designation and input of musical sound data can also be performed.

Sound source 8, DSP 9 and sound system 1
The tone output section consisting of 0 is for outputting a tone based on performance data. In other words, the tone generator 8 composed of software or hardware generates tone data based on the performance data processed and generated by this system, and the generated tone data is further subjected to digital signal processing by the DSP 9. The sound system 10 performs DA conversion (DAC), amplification (amplification), and sound emission (speaker).

In this embodiment, the performance data is a CD or F
In addition to music data from a portable recording medium such as D, the data can be input to the system from an external performance data generation device 13. That is, performance data such as MIDI can be received from the performance data generation device 13 connected via the interface 11.

[Main Processing] FIG. 2 is a flowchart of the main processing representing the entire performance data processing according to an embodiment of the present invention. In step R1, the system is initialized. In step R2, a panel setting for setting modes and parameters and a processing for processing performance data are performed in accordance with an operation of a panel operator of the operation panel 5.

In the next step R3, the performance operation device 6
Music data corresponding to an operation (key depression or the like) by the performance operator of the music data input unit, music data is read from the external storage device 4, or the performance data from the external performance data generating device 13 is transmitted to the interface 11 The data is input by inputting the data as music data via the.

In step R4, tone data is generated by the sound source 8 based on the music data generated by the processing in step R2 or the raw music data input in step R3, and the signal is processed by the DSP 9. The sound system 10 converts the signal from digital to analog, amplifies it with an amplifier, emits it as a musical sound from the beeker, and repeats the processing in steps R2 to R4 until there is an instruction to end the main processing. .

[Panel Setting and Processing] FIG. 3 shows an example of a panel setting and processing routine in step R2 of the main processing (FIG. 2). In the first step S1 of this routine, it is determined whether or not a setting input operation has been performed by a panel operator. If an operation has been performed, the process proceeds to step S2. If no operation has been performed, the panel setting and processing process ends. Then, the process returns to step R3 (FIG. 2). In step S2, it is determined whether or not the content of the setting input indicates "setting of automatic editing processing".
If there is an instruction for automatic editing process setting, step S
3. Proceed to step S4; otherwise, step S4
Go to 5.

In step S3, an edit target is set. This edit target is automatically set when the currently executed performance mode is real-time performance.
Set for the entire performance data. When the music data stored in the external storage device 4 is read and processed, "whether the entire music is to be processed"
“Which channel is targeted” or “Which channel is targeted (specified by channel or by tone type)” is determined by the setting of the panel control. You. Note that the real-time performance refers to processing musical tone data by operating the performance operator of the performance operator device 6 or processing performance data transmitted from the external device 13 as it is.

In the next step S4, an edit type is set. The setting of the edit type sets, for example, what kind of processing is performed on music data of a specified channel or tone color. For example, the guitar tone includes "bolt neck playing technique", "volume playing technique", and "mute ornamental sound addition". Step S
After the setting process of No. 4, the process returns to step R3 (FIG. 2).

On the other hand, if the instruction is not for automatic editing processing setting, it is determined in step S5 whether or not "execution of automatic editing processing" is instructed. If the instruction is for automatic editing processing setting, the flow proceeds to step S6. If not, step S
Go to 7. In step S6, it is checked whether or not "automatic editing processing" is set, and if it is set, the process proceeds to step S8 and subsequent steps in order to perform processing as set. If the automatic editing process is not set, the process proceeds to the setting flow of steps S3 and S4 described above.

In step S8, it is determined whether or not the designated music data has been recorded. That is, it is determined what performance data is to be processed, and if the processing of the recorded performance data has been designated, the process proceeds to step S9 to read the recorded music data. In the case of music data of a real-time performance, such as processing music data such as MIDI transmitted from the external device 13 as it is or processing music data based on a performance signal input from the performance operator 6, The process proceeds to step S10. In step S10, a process of directly loading the input music data of the real-time performance into the RAM 3 is performed. In the next step S11, when music data for a certain period of time capable of securing an analyzable data amount is accumulated. Next, the music data is read.

When the music data is read out in steps S9 and S11, the process proceeds to step S12, where the read music data is processed, and when the processing is completed, the process returns to step R3 (FIG. 2).

When the process proceeds from step S5 to step S7, an instruction for "other input" is executed in step S7. The “other inputs” include input items by various other setting operations such as “designation of automatic performance data”, “reading” of performance data, “playback start”, “edit instruction”, and “real-time performance” mode. There is. Then, after referring to these input items and executing corresponding processes, the process returns to step R3 (FIG. 2). For the setting operation of the “real-time performance” mode, the performance mode information is set to “real-time performance”.
And this information is reflected in the processing of step S3 and the like.

[Processing] FIG. 4 shows an example of a processing subroutine in step S12 of the panel setting and processing (FIG. 3). In this subroutine, first, in first to fifth steps S121 to S125, "tempo information", "position in musical piece of musical sound data to be processed" and "channel and tone to be processed" are detected, After detecting and analyzing various pieces of music information, such as analyzing a flow or detecting a music idea, the process proceeds to step S12.
The process proceeds to the characteristic changing process of No. 6.

In step S126, step S
Based on the items detected and analyzed in steps S121 to S125, a process of changing the characteristics of the music data to be processed in the music data is executed. After this characteristic change processing, step S12
At 7, the song data whose characteristics have been changed and the bar are newly recorded separately from the original in the external storage device 4 (original performance data is also recorded as necessary). Then, it is checked whether the simultaneous playback mode is set.

If the "simultaneous reproduction" mode is set, the flow advances to step S129 to perform a performance process using the corrected music data. That is, when the simultaneous reproduction is set, the processed performance data is output to the sound source 8, subjected to signal processing by the DSP 9, and emitted by the sound system 10. Then, after performing the reproduction process in step S129, or when the setting of the simultaneous reproduction is confirmed in step S128, the processing process is terminated and step R3 is performed.
It returns to (FIG. 2).

As described above, in the performance data expression processing apparatus of the present invention, the state of a plurality of musical tones (tempo, music position, tone color, flow of phrases and musical ideas) constituting the music performance data.
Are analyzed (S121 to S125), and based on the analysis result, the characteristic of the specific musical tone in the performance data is changed to a characteristic corresponding to the specified musical instrument playing style, and performance data of a predetermined tone (for example, guitar) is generated. (S126). Also, in advance, tone data or tone characteristic change rules corresponding to the playing style of the musical instrument corresponding to the predetermined tone color are stored, and based on the analysis result, the tone properties of the specific part of the performance data are changed according to the designated playing style. It can also be changed so as to correspond to the music data or music characteristic change rule. Note that the characteristic change processing can be executed with randomness or a predetermined probability.

[Characteristic Change Processing] FIGS. 5 to 7 show schematic processing flow examples of the characteristic change processing in step S126 of the processing processing (FIG. 4). In this example of the processing flow, first, in step T1, it is determined whether the tone detected in step S123 is a predetermined "tone A" (for example, a guitar), and if the tone is A, the process proceeds to step T2. If not, the process proceeds to step T3 (FIG. 7). Step T2
Then, it is further checked whether or not the simulated volume playing style is set. If it is determined that the simulated volume playing style is set, the process proceeds to step T4, and the simulated volume playing style processing described with reference to FIG. 8 is executed. Thereafter, the process proceeds to step T5. If not, the process immediately proceeds to step T5.

In step T5, it is determined whether or not a simulated bottleneck playing style has been set. If it is determined that the simulated bottleneck playing style has been set, the process proceeds to step T6, where the simulated bottleneck playing style described with reference to FIG. After executing the neck playing method processing, the process proceeds to step T7, and if not, the process immediately proceeds to step T7. In step T7, it is determined whether or not there is a setting for inserting a phrase. This phrase contains a mute ornament. When it is determined that the insertion of the phrase including the mute ornament is set, the process proceeds to step T8, and after performing the phrase insertion process described with reference to FIGS. 10 and 11, the process proceeds to step T9 (FIG. 6). Otherwise, the process immediately proceeds to step T9.

In step T9, it is determined whether or not the arpeggio special performance method is set. If it is determined that the arpeggio special performance method has been set, the process proceeds to step T10, in which the arpeggio special performance method processing described with reference to FIG. Is executed, the process further proceeds to step T11. If not, the process immediately proceeds to step T11. In step T11, it is determined whether or not there is a setting for adding vibrato. If it is determined that insertion of a phrase has been set, the process proceeds to step T12, where the vibrato adding process described with reference to FIG. Proceed to T13; otherwise, immediately proceed to Step T13.

In step T13, it is checked whether or not other changeable characteristic items are set to be changed. If there are any changeable characteristic items, the characteristic change process is executed. . Then, after the processing in step T13, the characteristic change processing ends, and the flow returns to step S127 (FIG. 4).

When the process proceeds from step T1 (FIG. 5) to step T3 (FIG. 7), it is determined whether the tone detected in step S123 is another "tone B", for example, a saxophone. If the tone color is B, the process proceeds to step T14; otherwise, the process proceeds to step T15. Step T
In 14, the same processing as in steps T2 to T13 is performed.
For the music data, the timbre B according to various conditions
Are performed, and after performing these processes, the process returns to step S127 (FIG. 4). Also,
In step T15, similarly to steps T2 and T3, it is determined whether or not there are still other timbres C, D,..., And if these timbres are the same, similar to steps T2 to T13 and T14, After performing processing for changing the characteristics corresponding to the tone colors C, D,... According to various conditions, the process returns to step S127.

[Simulated Volume Performance Method] FIG. 8 shows an example of a flow chart of the simulated volume performance method executed in step T4 of the characteristic changing process. In the first step VL1 of this processing flow, the tempo information detected in step S121 is compared with a certain predetermined value "X". As a result, if the tempo is slower (slower) than the predetermined value "X", the process proceeds to step VL2. If not, the process returns to step T5 (FIG. 5) of the characteristic changing process.

In step VL2, it is further determined whether or not the relevant portion of the music data is a section such as intro, ad-lib, ending, and the like. If so, go to step VL3; otherwise, return to step T5. I do.
In step VL3, it is further determined whether or not it is the start of the pulling. If so, the process of adding the volume rendition style is executed in step VL4. If not, the process returns to step T5. In the processing of the volume playing technique in step VL4. As shown in FIG. 14, for the portion determined as the position to which the volume playing technique is added,
What is necessary is just to change the characteristic of the music data so that the volume changes from MIN to MAX.

It is preferable that the simulated volume performance method processing conditions in steps VL1 to VL3 take into account the performance state of other parts. Such a condition is, for example, a part where the half note continues, as shown in FIG. 14, and a part other than the guitar part (particularly, the drum part) is resting, as shown in FIG. A part starting with a guitar part and keyboard strings is detected. Then, in step VL4, E
G, amplitude, volume, etc., the volume playing method of the guitar [For example, as shown in FIG. 14, picking is performed with the MIN (minimum value) of the volume knob of the guitar silent, and this knob is moved in the direction of MAX (maximum value). By turning it, a playing method of obtaining a violin-like sound rise] is realized. By realizing the volume playing method of the guitar in this way and obtaining a fairy tale effect,
It can be expressed like a guitar.

[Simulated Bottleneck Performance Method] FIG. 9 shows an example of a flow chart of the simulated bottleneck performance process executed in step T6 of the characteristic changing process. In the first step BN1 of this processing flow, the musical sound of the music data is examined, and it is determined whether or not an UP process for adding an Up slide to the preceding sound has been performed (BN6, BN9).
If the tone has been processed, it is determined in step BN2 whether or not the pitch of the musical tone is lower than the preceding tone. If it is determined in step BN2 that the sound is lower than the previous sound, in subsequent step BN3, a process of adding a Down slide is executed. In the DOWN processing of step BN3, randomness is given, and the addition rate is changed to change the Do rate.
wn slide is added. On the other hand, the first step BN1
If it is determined that the previous sound has not been subjected to the UP processing, the process proceeds to step BN4, and if it is determined in step BN2 that it is not lower than the previous sound, the process proceeds to step T of the characteristic changing process.
7 (FIG. 5).

In step BN4, it is determined whether or not DOWN processing for adding a Down slide to the sound before the musical sound has been performed (BN3). If the previous sound has been DOWN processed, the process proceeds to step BN5. Further, it is determined whether or not the pitch of the musical tone is higher than the preceding tone. If it is determined in step BN5 that it is higher than the previous sound, in step BN6, an UP process for adding an Up slide is performed in consideration of a predetermined condition. Step BN6 UP
In the processing, Up slides are added with randomness and at a different addition rate. On the other hand, if it is determined in step BN4 that the previous sound has not been subjected to DOWN processing, the process proceeds to step BN7, and if it is determined in step BN5 that it is not higher than the previous sound, the process returns to step T7.

In step BN7, it is further determined whether or not the musical tone is located at an intro, ad-lib, ending, etc., and if so, the process proceeds to step BN8. It is determined whether or not the sound is the first sound. If the sound is the first sound, the process proceeds to step BN9 to perform an UP process for adding an Up slide to the musical sound. In the UP process in step BN9, an Up slide is added with randomness and at a different addition rate. On the other hand, step BN
If it is determined in step 7 that the sound is not a position such as intro, adlib, or ending, and if it is determined in step BN8 that the sound is not the first sound, the process returns to step T7.

When a slide is generated in steps BN3, BN6, and BN9, each musical tone is processed so as to generate a deviation of several cents from the original pitch, and is added with randomness and a different addition rate. . In this case, it is preferable to use a process of adding vibrato to a sound having a long note length including an eighth note. As this vibrato, unique vibratos including those having unstable periods and modulation degrees are effective. By these processes, the instability of the pitch of each musical tone of the phrase can be produced. Furthermore, the sound generated by rubbing the strings when performing a slide performance is stored in advance as a “slide sound”,
This slide sound is added when a slide occurs.

In the simulated bottleneck playing method processing, it is possible to further add a sound not present in the score. Bottleneck playing often uses open tuned guitars to generate sounds other than notes on the score. Accordingly, the key of the music data is detected, and assuming a guitar tuned to the key, when a slide occurs, the sound of the position of the slide bar of the string adjacent to the musical tone is added. Also in this case, the randomness is given and the addition rate is changed.

[Phrase Insertion Processing] FIGS. 10 and 11
Shows an example of a flowchart of phrase insertion processing executed in step T8 of the characteristic change processing. In a first step PH1 of this processing flow, it is detected whether or not the tempo detected in step S121 is slower than a predetermined value "Y". If the tempo is slow, processing for adding a mute sound in steps PH2 to PH5 is performed. Is executed, and if not slow, the flow advances to step PH6 (FIG. 11) to proceed to the next phrase insertion processing.

In the first step PH2 of the process for adding a mute ornament sound, the music sound of the music data is
It is determined whether it belongs to a section such as ad-lib or ending. If it is in these sections, the process proceeds to step PH3; otherwise, the process proceeds to step PH6. In step PH3, it is determined whether or not the musical tone is the start of playing in the section. If the musical tone has begun to play, the process proceeds to step PH5. Otherwise, in step PH4, the musical tone is further set to a predetermined note state (8, 16). After the note tuplet). Here, if the state is after the predetermined note state, the process proceeds to step PH5; otherwise, the process proceeds to step PH6.

In step PH5, a process of adding a mute ornament sound stored in advance is executed. For example, sounds appropriately muted in a guitar are separately stored in a predetermined area of the external storage device 4 for about four sounds one by one. When a music data portion as shown in FIG. 15 (1) is detected, for example, in accordance with the automation criterion as in steps PH2 to PH4 described above, the stored mute sound data is read out in step PH5, and FIG. As described above, the mute ornament M is added to the detection portion so as to match the phrase, tempo, and the like. In this case, it is preferable to reduce the degree of addition (addition rate) and the number of decorative sounds to be added.

When the process proceeds to step PH6 (FIG. 11), it is determined whether or not the corresponding portion of the music data satisfies the condition a. The condition a is, for example, a portion suitable for hammering-on and pulling-off where the melody is rising or falling. If it is determined that the part is a relevant part, the process proceeds to step PH7 to perform a process of adding the articulation A to the corresponding portion of the music data, and then proceeds to step PH8. Otherwise, the process immediately proceeds to step PH8. move on.

In step PH7, for example, hammering on and pulling off are added as articulation A to the relevant portion. The hammering on and the pulling off are set in advance in a rule. That is, as in the example shown in FIG. 16, when the melody rises, the hammering-on H is used, and when the melody falls, the pulling-off P is often used. Therefore, hammering-on is generated alternately in the melody ascending portion determined in step PH6. The degree of occurrence can be increased or decreased to match the melody, rhythm, speed, etc. Also, as shown in FIG. 16, when returning to the same pitch as the immediately preceding pitch, a pull-off is generated. In this case, it is preferable that the volume of the hammering-on is lower and the volume of the pulling-off is higher than that of the hammering-on.

Here, an example of the hammering-on rule will be described. The resolution for the phrase is set in advance, and processing is performed on the notes extracted at the set resolution. For example, notes with the same pitch continue,
Resets the count of the number of target notes under the condition that a quarter-tone note continues, the note is falling, and performs the following processing: If the target note has a count of “2”, 1-2 When the target note has a count of “3”, 1-2 (2-
3) When the target note has a count of “4”, 2-3 (1-
2) If the target note is odd, then 1-2 (2-3). If the target note is even, then 2-3 (1-2). When the target note has a count of “3”, 2-3 (1-
2),

The rules for hammering on and pulling off include, for example:
Resets the count of the number of target notes when the condition that notes separated by more than a semitone continues continues and performs the following processing:-When the target note has a count "2", 1-2. In the case of 3 ", 1-2 (2-
3) When the target note has a count of “4”, 2-3 (1-
2) If the target note is odd, then 1-2 (2-3). If the target note is even, then 2-3 (1-2).

The occurrence of such hammering-on and pulling-off simply came to mind when the musical score data did not specify hammering-on or pulling-off, or when the user wanted to hear another instrument part as a guitar. This is an effective way to enter a melody and make it look like a guitar.

At step PH8, it is determined whether or not the corresponding portion of the music data satisfies the condition b. This condition b
Is a solo part such as ad lib, riff, ending, etc. If it is determined that the part is a relevant part, the process proceeds to step PH9, in which the articulation B of “chalking, hammering, pull-off, slide, etc.” prepared as MIDI data is added to the corresponding part of the music data. Perform addition processing.

For the processing in step PH9,
Several kinds of phrase data including articulations such as chalking, hammering, pull-off, and slide are prepared as MIDI data. These data are automatically converted on the system side even if the tempo and key are different so that they can be handled. Then, when the corresponding portion is detected in step PH8, necessary data is called and added to the portion. The phrase to be added includes a habit and feeling of a predetermined musical instrument, for example, a player (name player) of a guitar, and a characteristic display of the player can be realized.

Then, after the process of adding the articulation B in step PH9, or
If it is determined in H8 that the part is not the corresponding part, the insertion processing of this phrase is terminated, and step T of the characteristic change processing is performed.

[Arpeggio Special Performance Method Processing] FIG. 12 shows an example of a flowchart of the arpeggio special performance method processing executed in step T10 of the characteristic change processing. In a first step AR1 of this processing flow, it is detected whether or not the relevant portion of the music data is an arpeggio performance part, and if it is an arpeggio, the processing for the arpeggio special performance method in steps AR2 and AR3 is performed.関係 The relationship between the musical tones related to the geo is detected, and predetermined characteristics are added to the musical tones according to the relationship.
After this processing and if it is not an arpeggio, the process returns to step T11 (FIG. 6) of the characteristic change processing.

In the guitar arpeggio playing method, the sound in the arpeggio is played after the next sound is played, and the bass sound and the highest sound take a relatively long time for the next sound to come, so that the sound is kept growing. There are many. Therefore, in the special playing method processing according to the present invention, by giving the rules of the arpeggio as if a human is playing, it is possible to give an expression that makes the arpeggio of the guitar sound more natural. For this reason, first, in step AR2, the highest tone and the bass tone are detected, and correction is performed to give each tone of the arpeggio tuplet a predetermined volume.

In the correction of the tone length in step AR2,
For example, the following rules are used to automatically give the optimal duration for arpeggio tuplets: In each measure, the highest note having the highest pitch among the arpeggio tuplets (often corresponding to the first string and the second string) is detected, and the length of the detected highest note is increased. I do. 2. Each bar often corresponds to the sound of the fifth and sixth strings of the bass sound having the lowest pitch among the arpeggio tuplets. ) Is detected, and the length of the detected bass sound is lengthened. 3. Appropriate sound duration is given to the detected arpeggio component sound, and further expression is performed. 4. To correct the length of each musical tone, perform appropriate thinning,
Reduce its execution.

Next, in step AR3, as shown in FIG. 17, several kinds of velocities are automatically given to the musical tone in accordance with the pitch elevating pattern in the arpeggio. For example, the change pattern of the arpeggio pitch is shown in FIG.
As shown in FIG. 7 (1), in addition to a pattern that simply rises and a pattern that simply falls, there are a pattern that rises after falling and a pattern that rises and then falls. For example, several types of velocity patterns as shown in FIG. 17 (2) are prepared. Then, an appropriate velocity pattern is selected according to the detected elevation pattern of the arpeggio, and a corresponding velocity value is given to each musical tone. If there is a large pitch difference between adjacent sounds, such as in three-finger picking, and the strings are not adjacent, the velocity difference between the two sounds should be set to a relatively large value. Is preferred.

[Vibrato Addition Processing] FIG. 13 shows a flowchart example of the vibrato addition processing executed in step T12 of the characteristic change processing. In the first step VB1 of this processing flow, it is detected whether or not the musical tone of the music data has a duration corresponding to a note longer than an eighth note. In other words, in order to detect the place where the vibrato is added, it is determined whether the sound is a relatively long sound including the eighth note. If the note is a comparatively long note, the process proceeds to step VB2 as a vibrato addition target, and if not, step TB of the characteristic changing process.
13 (FIG. 6).

In step VB2, a vibrato depth value whose standard value is determined corresponding to a predetermined tone color, for example, a guitar tone color, is read out, and this is determined as a vibrato depth value (vibrato modulation degree) of the musical tone. . in this case,
For electric guitars, especially guitars with a distortion effect, increase the vibrato modulation depth,
For acoustic guitar, make it shallower. In the case of a nylon string guitar, a delicate vibrato with a small degree of modulation is added by swinging in a direction parallel to the string. Further, vibrato on a slide guitar adds vibrato that modulates in both high and low directions based on the center pitch of the pitch.

In step VB3 following step VB2, it is detected whether there is a plurality of vibratos added near the target musical tone to be added. If detected, the flow advances to step VB4 to execute the previous step. A vibrato waveform different from (previously added vibrato sound) is formed, and vibrato is added to the target musical sound based on the waveform. On the other hand, if there is no vibrato added especially in the periphery, the process proceeds to step VB5, and a vibrato waveform is formed based on the read standard value and added to the musical tone. In this way, the vibrato addition can be made random.

When it is determined that the vibrato to be added is too much, a target portion to which the vibrato is added may be selected at random, and the vibrato may be added with randomness. In addition, it is preferable to apply a delay to a portion to which vibrato is added. After the processing of steps VB4 and VB5, the process returns to step T13.

[Various Embodiments] Most typically, in order to acquire (input) performance data (song data), music data stored in the external storage device 4 of the system is read out, analyzed and analyzed. The music data to be processed may be data transmitted from the external device 13 in the MIDI format. In this case, even if the transmitted data is processed in real time, Once
The information may be stored in the external storage device 4 (for example, an HDD) and then read and processed. In addition, the characteristics of musical tones may be changed in accordance with the tone generation instruction data obtained by operating the performance operator 6 attached to the system. In this case, the tone may be processed in real time. And then read it out for processing.

[0082]

As described above, according to the present invention, a plurality of musical tones constituting performance data are analyzed, and the tempo, key, tone, position of musical tones, mutual relation of musical notes, tone generation instruction status of musical tones, Determine the conditions for applying the playing style of the musical instrument corresponding to the predetermined tone, such as the musical idea and the flow of the phrase, and then, according to the results, specify the characteristics of the pronunciation for each specific musical tone in accordance with the specified playing style. It changes or adds characteristics corresponding to previously stored musical tone data or characteristic changing rules, so that the tone of the pitch selected by the selected tone is not a sound, but Automatically determines a target to which a sound quality characteristic peculiar to a musical instrument operation that is entered by operating the musical instrument should be given, and adds an appropriate characteristic to the target. Therefore, it is possible to more naturally express emotions, environments, and atmospheres, and to generate performance data sufficiently expressed according to the musical instrument playing style.
