2. Description of the Related Art With the spread of personal computers in recent years, anyone can play music using DTM (desktop music) that plays, composes, arranges, and synthesizes timbres using computers. It's becoming free and easy to enjoy. Especially the recent DT
In M, by automatically arranging a desired note or musical symbol on a staff displayed on a display screen such as a display and performing score editing, performance information corresponding to the score is automatically generated. You can do it. According to this, for example, MIDI (Musical Instrume
nt Digital Interface) Even if the user has little specialized knowledge about the standard, or has little musical knowledge such as not being able to read notes, a more natural performance, a beautiful performance, a lively performance, a habit It is possible to generate performance information capable of performing various performances with different expressions such as a unique performance by a simple operation such as editing a score. In such a DTM, the score display information for displaying the score on the display screen and the performance information for reproducing the music corresponding to the displayed score (that is, automatic performance) are separately provided from the start to the end of the score. I remember about the whole score.

[0003]

By the way, the above-mentioned D
In the conventional score display device used in TM etc.,
There is a section where the corresponding score can be displayed only with the performance information. That is, even if the score display information for displaying such a score is not stored for the section for displaying a simple score, the corresponding score can be displayed if there is performance information for such a section. Nevertheless, in the conventional score display device, since the score display information and the performance information are not associated with each section, the score display is performed even for the section where the corresponding score can be displayed if there is the performance information. I had to display the score using information. Therefore, as described above, it is necessary to store both the score display information data and the performance information data for the entire score. in this way,
As for the section where the score can be displayed only by the performance information, the score display information had to be stored in duplicate with the performance information, so the amount of information was unnecessarily increased and the song As the number increases, a large storage capacity is required, which is inconvenient.

The present invention has been made in view of the above-mentioned points. The score display information is stored only for a section in which a complicated score is displayed, and the performance information is used for a section in which a simple score is displayed. An object of the present invention is to provide a score display device and a score display program for displaying a score by using the score display information for a section displaying a complicated score.

It is characterized in that the score display in the score display means is completed by using the information and the score display information in combination.

According to the present invention, according to the score display information for displaying the score corresponding to the predetermined performance section only in the predetermined performance section in the performance information, the performance information for playing the predetermined music in the other performance sections. By displaying the score according to the above, it is possible to display a clean score as in the conventional case even with a small amount of information. That is, performance information for playing a predetermined music piece is stored in the first storage means, and score display information for displaying a score corresponding to a predetermined performance section in the performance information is stored in the second storage means. It should be noted that the musical performance information can be displayed accurately using the performance information, and the musical performance information can be used as it is, and the musical performance information can be displayed for the musical performance section that cannot be accurately displayed using the musical performance information. The score is displayed without using the score display information. Thus, the musical score display is completed by using the performance information and the musical score display information in combination. In this way, the musical score is displayed according to the dedicated musical score display information for displaying the musical score only for a predetermined performance section of the musical performance information, and the musical score is displayed for the other parts according to the musical performance information for musical composition performance. While reducing the amount of information required for, it becomes possible to display a clean musical score as in the conventional case.

That is, the timer 1A generates clock pulses for counting time intervals and for setting a performance tempo to be used when a music piece is reproduced in accordance with the performance information in the music information generated by the score editing. Such a clock pulse from the timer 1A is given to the CPU 1 as a processing timing instruction or is given to the CPU 1 as an interrupt instruction.
The CPU 1 executes various processes according to these instructions.

The ROM 2 includes various control programs (for example, programs for music information editing processing described later) executed by or referred to by the CPU 1, various data (for example, music symbol definition table and music template described later), and a plurality of musics. It stores a plurality of music symbol image data for displaying each of the symbols, note image data for displaying notes, and the like. The RAM 3 includes music information representing one music score and music corresponding to the music score generated by the music score editing operation by the user (as described later,
(Including performance information and musical score display information) and various data generated when the CPU 1 executes a predetermined program, as a working memory, or a control program currently being executed and data related thereto. It is used as a memory etc. A predetermined address area of the RAM 3 is assigned to each function and used as a register, a flag, a table, a memory, or the like.

Now, the music symbol definition table and the music template stored in the ROM 2 will be briefly described. First, the music symbol definition table will be described. The music symbol definition table contains type definition information for each music symbol, that is, all the music symbols that can be input on the staff displayed on the display device 6A (for example, the display) during score editing. Is the definition information for classifying into a predetermined type. The music symbols can be roughly divided into predetermined types, and the first type is for the entire song (for example, all melody parts related to melody, accompaniment parts related to bass and chord performance, all rhythm parts related to rhythm accompaniment). Symbols that have a musical influence, as a second type, have a musical influence only on one part, and the image data of the prepared musical symbols can be displayed as they are without the need to edit the note display. As a third type of symbol to be used, it has a musical effect on notes at specific points in one part, and requires editing of the note display at specific points. There is a symbol for generating new image data for display and using it for display. The music symbols classified into the first type are music symbols mainly used for controlling the tempo (for example, allegro or ritardando), and in this embodiment, such music symbols are called "master independent symbols". Second above
Music symbols classified into types are music symbols mainly used to control the volume of each part (for example,
Meso-Forte, Pianissimo, etc.), such musical symbols are referred to as “(usually) independent symbols” in this example. The musical symbols classified into the above-mentioned third type are mainly used for changing the pitch of notes, changing the pronunciation length, continuously connecting to adjacent notes, and adding ornamental sounds. It is a musical symbol (for example, choking, trill, etc.), and in this embodiment, such a musical symbol is called a “decoration symbol”. The above-described music symbol definition table is prepared in advance in the ROM 2 in order to classify each music symbol input on the staff by the user into any of the above three types.

Next, the music template will be briefly described. A music template is roughly divided into data composed of music symbols and information representing a method for creating reproduction data (described later) from display data (described later). That is, each song template stores a method of creating reproduction data for each music symbol, and creates tone control information (that is, reproduction data) for realizing musical characteristics according to each music symbol using display data. Is able to. For example, the correspondence between a musical symbol and musical tone control information for facial expression is set as a rule in a predetermined facial expression algorithm, and generation method information representing this facial expression rule is stored in advance for each musical symbol (that is, A music template) and musical tone control information are generated and added to the performance information according to a facial expression assigning algorithm corresponding to the inputted musical symbol. Regarding the generation of musical tone control information using such a music template and display data, there is, for example, Japanese Patent Laid-Open No. 2001-159892 filed by the present applicant.

In the music information editing apparatus as described above, the operator 5A, the display device 6A, the sound source circuit 7, etc.
It goes without saying that the device is not limited to being built in one device body, but may be configured separately and connected to each device using a communication means such as a MIDI interface or various networks. Nor.

In the music information editing apparatus shown in FIG. 1, the user places a desired note or musical symbol at an appropriate position on the staff displayed on the display device 6A using a mouse or the like. By going, it is possible to generate predetermined music information. The generated music information is information representing one music, and is data including music score display information for displaying a predetermined music score on the display device 6A and performance information for reproducing music corresponding to the music score. Therefore, the music information generated in accordance with the music score editing operation in the music information editing device to which the music score display device according to the present invention is applied, that is, the respective data structures of the performance information and the music score display information will be respectively described with reference to FIGS. explain.

First, the data structure of the performance information included in the music information will be described with reference to FIG. FIG. 2 is a conceptual diagram showing an example of a data structure of performance information. This performance information is data for reproducing one entire music piece generated in accordance with the score editing operation, and is composed of a plurality of parts recorded in a predetermined file format such as a conventionally known SMF (Standard MIDI File) (or This is data of a plurality of tracks).

As can be understood from FIG. 2, the performance information can be roughly divided into one master track data and a plurality of track data. The master track data is information for setting various reproduction modes used when reproducing music, and for example, tempo data that defines a performance tempo used during automatic performance, tone color data that defines a tone color, and volume that defines a volume. Including data etc. This master track data is data commonly used for all track data. On the other hand, each track data such as the first track, the second track, ... Is the information indicating the reproduction content of the automatically played music, and each part (for example, a melody part regarding a melody, an accompaniment part regarding a bass or chord performance, a rhythm). This is data in which a set of timing data and event data for each rhythm part regarding accompaniment is stored in the order of progress of reproduction.

The timing data stored in each track data is data representing the time (that is, the timing) at which various event data for reproducing music such as pronunciation and mute should be processed, and the number of clocks according to the MIDI clock. It is data that can be represented by. This timing data indicates the timing at which the event should be processed, as the absolute time (that is, the absolute number of clocks) from the beginning of the song or the beginning of each bar, or the relative time from the previous event (that is, relative time). The number of clocks). The event data stored in each track data is data representing the contents of various events for reproducing music such as pronunciation and mute. The contents of these various events include key-on, key-off, tempo change, tone color change, etc., and music reproduction (that is, automatic performance) is performed based on these events. An identifier (ID) representing object data (see FIG. 3 described later) corresponding to the event data is added to the timing data and the performance event data as needed. That is, the identifier ID is added only to the timing data and performance event data in which the object information exists, and the performance event and the object data (specifically, display data) are made to correspond by this identifier ID. There is. As this identifier (ID), one unique identifier (ID) is assigned to one score editing. For example, unique symbols such as ID1, ID2, ID3, ... Are assigned as identifiers (IDs) for each musical score edit.

It should be noted that the performance information is not limited to the one in which the master track data and each track data are continuously stored in the storage area as shown in FIG. 2, but is stored in scattered storage areas in a scattered manner. May be. For example, the master track data and each track data may be stored in different memories. However, in this case, it goes without saying that it is necessary to separately manage the scattered data as continuous data. For example, by preparing a table in which master track data and each track data are associated with each other, and referring to this table, 1
You may decide one performance information. Furthermore, timing data and performance event data relating to a plurality of parts may be mixedly stored in one track data. In this case, track identification data for identifying a track is added to each timing data and performance event data. It is good to do it.

Next, the data structure of the score display information included in the music information will be described with reference to FIG. Figure 3
It is a conceptual diagram which shows one Example of the data structure of score display information. The musical score display information is data for displaying the musical score related to the music symbol input at the time of editing the musical score on the display device 6A, and is stored in association with the performance information regarding the input music symbol. .

As can be understood from FIG. 3, the score display information can be roughly divided into object information and ID list information. The object information is a plurality of object data (first object, second object,
..) and each object data includes an identifier (ID) and display data. Identifier (ID)
Is data for identifying individual object data, and a unique symbol (for example, ID1, ID2, ID3, ...) Is attached to each object data. By this identifier (ID), each object data is associated with the timing data and performance event data of the performance information to which the same symbol identifier (ID) is attached. The display data is data for creating a display image such as a music symbol input according to the score editing or a note edited by the music symbol, and the music in the score editing is displayed on the staff displayed on the display device 6A accordingly. It is possible to display the musical score of the content according to the input of the symbol. The display data includes the timing data for displaying the score and the event data for displaying the score in the order of progress of performance (that is, the display order of the scores displayed on the display device 6A).
Remember. For example, when a decoration symbol is input during score editing, the input decoration symbol and a series of notes and other decoration symbols attached to the decoration symbol (that is, the input decoration symbol causes a musical influence). Data representing all of the above) is recorded in the display data as one event data that is a combination of the note event and the decoration symbol event. The note event is data representing the content of the note to be displayed. The decoration event is data representing the content of the decoration symbol to be displayed. The musical score display timing data is data representing the display position of the note event data (or the event data in which the note event and the decoration symbol event are combined) on the display device 6A. The musical score display timing data is data represented by the same clock number as the MIDI clock similar to the timing data in the performance information described above. When an independent symbol is input during score editing, only data representing the independent symbol is recorded as one event data.

The ID list information is data in which the identifier (ID) information used for each track is recorded in the order of display. The master track ID list records master independent symbols, that is, identifiers (IDs) assigned to symbols that affect all parts (or tracks).
The first track ID list is an independent symbol or a decorative symbol, that is, an identifier (ID) attached to a symbol affecting the first track (part) is added to the decorative symbol ID list or the independent symbol ID list for each symbol. Classify and record.

In the music information editing apparatus shown in FIG. 1, the user uses a mouse or the like to place musical notes or musical symbols at appropriate positions on the staff displayed on the display device 6A. Then, music information can be generated. In particular, when the user inputs a music symbol on the staff, the score display information for displaying the score in accordance with the score editing operation is generated, and the generated score display information and the prepared song template are used. An identifier (ID) is added to the reproduction data corresponding to the created score edit and stored in a predetermined position of the performance information. Therefore, a music information generation process, that is, a music information edit process for generating music score display information and performance information, which is performed along with the score editing by the user on the staff displayed on the display device 6A, will be described. FIG. 4 shows C in the music information editing apparatus shown in FIG.
It is a flow chart which shows an example of "music information edit processing" which is performed in PU1. This "music information editing process"
Is a process that operates from the start of the program to the end of the program. The operation of this process will be described below with reference to the flowchart shown in FIG.

In step S1, a staff is displayed. That is, in order for the user to place a note or a musical symbol at an appropriate position using a mouse or the like to easily generate a music,
The staff is displayed on the display device 6A. In step S2, it is determined whether or not an instruction to display the score on the display device 6A by selecting the created music information is given. The instruction to select and display the created music information is an instruction issued when editing the existing music information, or when creating new music information while using the existing music information. If there is an instruction to select the created music information and display the score (YE in step S2)
S), "display score" processing is performed (step S3). In this "display score" processing, the score is displayed on the display device 6A in accordance with the selected music information. That is, when the user uses the operator 5A or the like to select desired music information from the music information stored in advance in the ROM 2, the RAM 3, the external storage device 8 or the like, the display device 6A displays the music information according to the selected music information. Musical notes and musical symbols are sequentially displayed at predetermined positions on the staff displayed in step 1 to complete the score display of a predetermined music piece (details will be described later). on the other hand,
If there is no instruction to select the created music information and display the score (NO in step S2), the above "display score" process is not performed, and the process proceeds to step S4. In other words, when creating new music information from the beginning to the end without using existing music information, it is not necessary to select the created music information and give an instruction to display the score. Not done Therefore, in such a case, the "display of score" processing is not performed.

In step S4, it is determined whether or not there is an instruction to input a performance event. That is, the user adds a new note on the staff by using the manipulator 5A or the like, or edits a note already displayed on the staff (specifically, deleting the note or changing the placement position of the note). , Or change of note type) is determined. If there is an instruction to input a performance event (YES in step S4), the data of the input performance event is written in the corresponding position of the performance information (step S5). For example, when a new note is added to the staff, the performance event data related to the input note is written to the corresponding position in the performance information, and when the note already displayed on the staff is edited, the performance is played. Delete the existing performance information at the corresponding position of the information,
The performance event data relating to the input note is written in the corresponding position of the performance information. Then, the display of the score of the edited portion is changed to the display of the score according to the content of the edited performance information (step S6). That is, the display on the staff is changed from the score display before editing to the score display after editing. On the other hand, if there is no instruction to input a performance event (NO in step S4), the processes in steps S5 and S6 are not performed.

In step S7, it is determined whether or not there is an instruction to input a music symbol event. That is, the user newly adds a music symbol on the staff by using the operator 5A or the like, or edits a music symbol already displayed on the staff (specifically, deleting the music symbol or deleting the music symbol). It is determined whether or not there is an instruction such as a change of type) or an instruction to edit a note affected by a musical symbol (that is, a note event included in the object information). When there is no instruction to input the event of the musical symbol (NO in step S7), step S11
Jump to the process of. On the other hand, if there is an instruction to input the event of the musical symbol (YES in step S7)
S), it is determined whether or not the input music symbol is an independent symbol (step S8). If the input music symbol is an independent symbol (YES in step S8), an "independent symbol edit" process is executed (step S9). If the input music symbol is not an independent symbol, that is, if it is a decoration symbol (NO in step S8), an "edit decoration symbol" process is executed (step S10). In these "independent symbol editing" processing or "decoration symbol editing" processing, the data relating to the event of the input musical symbol is written into the performance information and the score display information in the music information, respectively. Since such processing will be described later, detailed description thereof is omitted here. When the reproduction of the music is instructed, the music is reproduced according to the performance information in the music information (step S11). For example, SMF (Sequ
ential MIDI File) is used for automatic performance processing. In step S12, it is determined whether or not there is an instruction to end the music information editing program. If there is an end instruction (YES in step S12), the process ends. If there is no end instruction (NO in step S12), the process returns to step S2 and the above step S2 is performed.
By repeating the processing from 2 to step S12,
The music information generation process according to the score editing operation is continuously executed.

Here, with respect to the "musical score display" process started in step S3 of the "music information editing process" described above,
This will be described with reference to FIG. FIG. 5 is a flowchart showing an example of the “musical score display processing”. First, the score corresponding to the performance information of the selected music information is displayed (step S21). That is, according to the timing data of the performance information and the performance event data, the display device 6A
The musical score is displayed by placing notes and rests at appropriate positions on the staff. At this time, the timing data and the performance event data to which the identifier ID is added are extracted from the performance information of the selected music information, and the respective data to which the extracted identifier ID is added are not displayed. Set in advance. Therefore, the musical notes displayed on the display device 6A by the processing of step S21 do not display the notes or the like affected by the decoration symbol. In step S22, it is determined whether or not there is an ID list in the ID list information. That is, the musical composition has already been subjected to some score editing for the master independent symbol, the independent symbol, and the decorative symbol, and the ID list of the ID list information in the score display information (that is,
Master track ID list, first track ID list,
It is determined whether or not the identifier ID has been registered in at least one of the ID lists of the second track ID list, ...

If there is no ID list in the ID list information (NO in step S22), the process ends. That is, in this case, the music is not edited in some way with respect to the master independent symbol, independent symbol, decoration symbol, or the like, and in the process of step S21, all the scores related to the song are displayed on the staff. Since it is displayed, the processing is ended without performing the processing of steps S23 to S32 described later. On the other hand, if the ID list information includes an ID list (YES in step S22), the ID lists for all tracks (that is, the first track ID list, the second track ID list, ...) Are added to the decoration symbol ID list. It is determined whether or not the data is recorded (step S2
3). If the data is recorded in the decoration symbol ID list (YES in step S23), that is, if the score is the score of the musical composition for which the score editing for the decoration symbol is performed, the identifier is selected from the decoration symbol ID list. The ID is read, and the display data corresponding to the identifier ID is read from the object information (step S24). Then, the score data to be displayed (specifically, the display image) is created using the read display data (step S2).
5) The data of the created score is displayed at the corresponding position on the staff (step S26).

The musical score data creation process executed in step S25 is performed by a dedicated program other than the "musical score display process" program. That is, regarding the display of the decoration symbol, the display position of the decoration symbol must be adjusted according to the display position of the note. Therefore, in order to perform such a display-related process quickly and efficiently, a display image of a musical score to be displayed on the staff is created using display data read from the object information according to a dedicated program. In this way, the data related to the decoration symbol input according to the score display is stored in the score display information different from the performance information, and the display image related to the decoration symbol is collectively created by the dedicated program using the score display information. By doing so, there is an advantage that such a score can be displayed more quickly and efficiently.

In step S27, it is determined whether or not data is recorded in the independent symbol ID list for the ID lists (that is, the first track ID list, the second track ID list, ...) For all tracks other than the master track. judge. If data is recorded in the independent symbol ID list (YES in step S27), that is, if the score is the score of a musical composition in which the score related to the independent symbol is edited, the identifier is selected from the independent symbol ID list. The ID is read, and the display data corresponding to the identifier ID is read from the object information (step S2
8). Then, the image data prepared in advance corresponding to the music symbol indicated by the read display data is read and displayed at the corresponding position on the staff (step S2).
9). In step S30, it is determined whether or not data is recorded in the master track ID list of the score display information. If data is recorded in the master track ID list of the score display information (YES in step S30)
S), that is, when the score is a score of a musical composition in which the score of the master independent symbol is edited, the identifier ID is read from the master track ID list, and the display data corresponding to the identifier ID is read from the object information. Read out (step S31). Then, the image data prepared in advance corresponding to the read display data is read and displayed at the corresponding position on the staff (step S32). The display of these independent symbols and master independent symbols does not need to be displayed in combination with the display of musical notes, unlike the display of decorative symbols described above. It is only necessary to display it at the position represented by the timing data in the data), and there is no need to display it while adjusting the display position of the independent symbol or master independent symbol according to the display position of the note. It can be displayed without using a program.

As described above, in the "score display process" shown in this embodiment, the display of the timing data and the performance event data to which the identifier ID is not attached and the timing data and the performance event to which the identifier ID is attached are displayed. Separately display the data display. That is, the score related to the data to which the identifier ID is not attached is first displayed according to the performance information, and the master independent symbol or the independent symbol or the decoration symbol (that is, the data to which the identifier ID is attached) is displayed on the display. Display additionally. At this time, for displaying the timing data and the performance event data to which the identifier ID is not attached, the SMF data is used as it is because it is an ordinary note (that is, a note that is not edited with music symbols). Display processing. On the other hand, the display of the timing data and the performance event data to which the identifier ID is added is edited by some musical symbol, so that the master independent symbol or the master independent symbol is used without using the SMF data. The display processing may be performed by using the display data of the portion where the score editing is performed for the independent symbol or the decorative symbol. In this embodiment, the display of the entire musical score is completed by displaying the musical notes for all tracks, the decoration symbols for all tracks, the independent symbols for all tracks, and the master independent symbol for the master track in this order. Has become. As described above, the entire musical score is displayed on the display device 6A by using the display data of the musical performance information and the musical score display information in combination in accordance with the contents of the musical score editing.

In the above-mentioned "musical score display processing", timing data and performance event data with an identifier ID are extracted from the performance information of the selected music information, and the extracted identifier ID is added. Although the display of each data is not performed, the display is not limited to this. For example, when displaying the score in step S21, regardless of the presence or absence of the identifier ID, all the timing data and the performance event data in the performance information are displayed, and in each processing from step S23 to step S32. For the display of the timing data and the performance event data to which the identifier ID is added, the already displayed content may be replaced with the displayed content or may be overwritten.

Next, the "editing of independent symbols" process started in step S9 of the "music information editing process" will be described with reference to FIG. FIG. 6 is a flowchart showing an example of the "independent symbol editing process". In step S41, an ID number (that is, an identifier ID) that is not used in the music information is detected and set as a new ID number. For example, if master independent symbols, independent symbols, or decorative symbols have already been added to the score, and up to "ID5" have already been used as ID numbers for these musical symbols, "ID6" will be used as the new ID. Number. In step S42, display data corresponding to the input music symbol (here, an independent symbol) is created. The display data corresponding to the independent symbol created here is instruction data for reading out image data for displaying the independent symbol.
That is, according to the instruction data, the image for display prepared in advance for each independent symbol is read out, so that the independent symbol is independently displayed on the score. In step S43, the new ID number and the created display data are added to the object information as one object data. The display data added in this case is data for displaying the input independent symbol on the staff, and only the data for displaying the independent symbol is recorded. In step S44, the new ID number is set to ID.
Write to the corresponding position in the corresponding list of list information. For example, when the music of the melody part is recorded as the first track and the independent symbol is added to the desired performance part of the melody part, the independent symbol ID list of the first track list in the ID list information. A new ID number is written at a predetermined position (see FIG. 3) (that is, a position in the order corresponding to the performance progress of the symbol edited this time). In step S45, reproduction data is created according to the created display data and a predetermined music piece template prepared in advance, and the created reproduction data is written at a position corresponding to the performance information calculated by timing detection or the like. The reproduction data created in this case is data for reproducing the music corresponding to the independent symbol. When writing the created reproduction data in the performance data, an identifier ID having the same ID number as the ID number is added. In step S46, the image data prepared in advance corresponding to the music symbol indicated by the created display data is read out and displayed at the corresponding position on the staff. A specific example of the performance information and the score display information (including the object information and the ID list information) recorded by the "independent symbol editing process" will be described later, and thus detailed description thereof will be omitted.

In the above-described embodiment, the reproduction data created according to the display data and the song template is recorded only in the performance information, but the reproduction data created in the object information is recorded together with the performance information. You may leave it. This is convenient when sequentially editing the score while using a plurality of music symbols. In particular, it is convenient in the "undo function" that can sequentially return the musical score editing state to the editing state one step before according to the operation. That is, by recording the reproduction data in the object information together with the identifier ID and the display data, the reproduction data is recreated in accordance with the display data of one step before and the corresponding song template each time the "undo function" is used. Even without it, the performance information can be easily rewritten to the edited state one step before.

Next, the "editing of decoration symbol" processing started in step S10 of the "music information editing processing" described above will be described with reference to FIGS. 7 and 8. 7 and 8 are flowcharts showing one embodiment of the "decoration symbol editing process", FIG. 7 is a flowchart showing the first half process, and FIG. 8 is a flowchart showing the latter half process. That is, the process shown in FIG. 8 is a process that is continuously executed after the process shown in FIG. 7.

First, the first half of the "edition symbol editing" process will be described with reference to the flowchart of FIG. In step S51, a performance event affected by the input music symbol (here, a decoration symbol) is detected from the performance information. In step S52, the detected performance event is deleted from the performance information. In step S53, the display corresponding to the deleted performance event is erased. That is,
The note display is erased from the staff displayed on the display device 6A. However, this processing may not be performed, and the note display that affects may be left as it is and a new image may be overwritten and displayed.

In step S54, it is determined whether the performance event detected in step S51 has an identifier ID added. That is, before adding the decoration symbol, it is determined whether or not it is a performance event to which some music symbol is already added. When the detected performance event is not the one to which the identifier ID is added, that is, when the decoration symbol of this time is the music symbol added to the performance event for the first time (N in step S54).
O), display data is created from the detected performance event and the input music symbol (step S55). On the other hand, if the detected performance event is the one to which the identifier ID is added, that is, the performance event to which some music symbol has already been added (Y in step S54).
ES), display data is read from the object data corresponding to the added ID (step S56), and new display data is created from the read display data and the input music symbol (step S57). That is, the display data for displaying both the previously input music symbol and the currently input decoration symbol is newly created. In step S58, an ID number (identifier ID) not used in the music information is detected and set as a new ID number. In step S59, the new ID number and the created display data are added to the object information as one object data. It should be noted that the object information taken in the object information added at this time (that is, the object information regarding the previously input music symbol) may be deleted. In step S60, the new ID number is set to I
Write to the corresponding position in the corresponding list of the D list information. For example, when the music of the melody part is recorded as the first track and the decoration symbol is added to the desired performance part of the melody part, the decoration symbol ID list of the first track list in the ID list information. A new ID number is written at a predetermined position (see FIG. 3) (that is, a position in the order corresponding to the performance progress of the symbol edited this time). Then, the ID of the object data captured in the newly created object data (that is,
The ID of the object data read in step S56) is deleted from the decoration symbol list.

Next, the processing of the latter half of the "decorative symbol editing" processing will be described with reference to the flowchart of FIG. In step S61 of FIG. 8 following step S60 of FIG. 7 described above, it is determined whether or not there is an instruction not to edit the performance information when the decoration symbol is input. When giving an instruction not to edit the performance information, the decoration symbol may be input while pressing a predetermined operator such as a "SHIFT" switch. If there is an instruction not to edit the performance information when the decoration symbol is input, for example, "SHIFT"
If the decoration symbol is input while pressing the switch (YES in step S61), blank data is written at the position of the performance information where the reproduction data created by the created display data and the performance information should be written (step S61). S6
2). The blank data is data indicating that the playback data should have been recorded at the position of the data, but the playback data was not recorded, and it is the time range (that is, the display data of the edited symbol that the edited symbol affects). Performance time corresponding to the displayed image) and an ID number added to the object data of the edited symbol. On the other hand, when there is no instruction not to edit the performance information when the decoration symbol is input, for example, when only the decoration symbol is input without pressing the "SHIFT" switch (NO in step S61), it is created. Reproduction data is created according to the displayed data and a previously prepared song template, and the created reproduction data is written in a position corresponding to the performance information (step S63). At this time, a new ID number (see step S58) is added to all the event data in the created reproduction data. In step S64, score data to be displayed is created using the created display data. This musical score data creating process is performed by a dedicated program different from the "decorative symbol editing process" program. In step S65, the created score data is displayed at the corresponding position on the staff. A specific example of performance information and musical score display information (including object information and ID list information) recorded by this "decoration symbol editing process" will be described later,
Detailed description here is omitted.

Next, the "direct input" processing for editing the blank data of the performance information by directly inputting the performance event without the score editing using the staff notation will be described with reference to FIG.
Will be explained. FIG. 9 is a flowchart showing an example of the “direct input process”. In step S71, it is determined whether or not there is an instruction to input a performance event. For example, it is determined whether or not the user has given an instruction to directly input the performance event by inputting the performance event by using a piano roll or the like, or by inputting the performance event by inputting a numerical value. . If there is no instruction to enter a performance event (step S
No of 71), the said process is complete | finished. If there is an instruction to enter a performance event (YES in step S71)
S), it is determined whether or not there is blank data at the timing instructed to input (step S72). If there is blank data at the input timing (step S
72: YES), the identifier I added to the blank data
D is added to the input performance event and the data is written to the corresponding position of the performance information (step S7).
3). In this way, the performance event directly input and the display data of the object information are associated with each other by the identifier ID. If there is no blank data at the input instruction timing (NO in step S72), the performance information is rewritten based on the input performance event, and the score display is changed (step S74).

Here, the display contents displayed on the display device 6A during the music information editing process, the recording information recorded in the performance information and the score display information (including the object information and the ID list information) are shown for each score editing content. It demonstrates sequentially using 10-FIG. 10 to 16 shown below
In each of the above figures, a musical score display example on the display device 6A, performance information created when the input shown in the musical score display example is made, and objects created when the input shown in the musical score display example is made in order from the top A specific example of the information and the ID list information created when the input shown in the musical score display example is made will be shown. Further, the data added along with the score editing is shown surrounded by a thick frame. It should be noted that in the following description, a case will be described in which the musical score is edited only for the musical composition of the first track (for example, the melody part).

First, as the score editing, only the ordinary notes (that is, the notes to which no musical symbol is added) are displayed on the display device 6A.
The music information editing process in the case of inputting on the staff displayed on the screen will be described with reference to FIG. Figure 10
[Fig. 7] is a conceptual diagram for explaining a music information editing process when only normal notes are input.

As shown in the score display example of FIG. 10, only ordinary notes such as note A, note B, note C, and note D are input on the staff displayed on the display device 6A in the order of progress of the musical score. When editing is performed, Y is selected in step S4 of FIG.
Since it is determined to be ES and NO in step S7, only performance information is created and score display information is not created. That is, for the score display information, the note A
~ When the note D is input, neither the master independent symbol, the independent symbol, nor the decoration symbol is input. Therefore, the object information and the ID list information (that is, the decoration of the master track ID list and the first track ID list) Symbol ID
No data is recorded in the list and the independent symbol ID list). On the other hand, with respect to the performance information, no data is recorded on the master track, but on the first track, each timing data of note A to note D and each note event data (in the figure, for example, timing data of note A is shown. Together with the note event data of the note A are simply displayed as “note A”) in time series, that is, in the order of performance progress (step S5 in FIG. 4). An identifier ID is given to each timing data of note A to note D and each note event recorded on the first track of the performance information in this way.
Is not added. Therefore, in this case, only the timing data of each of the notes A to D and the note event data of the notes A to D are read out from the performance information and the display processing is performed, and the musical score including only the normal notes as shown in FIG. Is displayed (step S6 in FIG. 4).

Next, as score editing, a decoration symbol (choking in this embodiment) is added to the score display shown in FIG.
The music information editing process in the case of inputting will be described with reference to FIG. FIG. 11 is a conceptual diagram for explaining the music information editing process when a decoration symbol is input.

As shown in the musical score display example of FIG. 11, of the musical notes A, the musical notes B, the musical notes C, and the musical notes D displayed on the display device 6A, the musical notes B (indicated as musical notes b as a new musical score display in the figure). To note C (note c is displayed as a new musical score display in the figure) is edited to perform choking, it is determined as NO in step S8 of FIG. 4, and the musical score display information is created and the performance is performed. The corresponding part of the information is edited. That is, for the score display information, the identifier ID “ID
The display data “note b + cho (choking symbol) + note c” (data for performing the display surrounded by the dotted line in the score display example shown in the figure) to which “1” is added is recorded in the order of creation (step S59 in FIG. 7). ). First of ID list information
In the decoration symbol ID list of the track ID list, the same identifier ID “ID1” as the identifier ID recorded in the first object of the above object information is recorded in the order of performance progress (step S60 in FIG. 7). On the other hand, for the performance information, no data is recorded on the master track, but the created reproduction data is recorded on the first track in place of the data of "note B" and "note C" ( Step S63 in FIG. 8). The reproduction data is data generated according to the display data and a music template prepared in advance. For all performance events included in the reproduction data created in this way, the identifier ID “ID
1 ”is added. Therefore, in this case, the note A and the note D are displayed by processing the timing data and the note event of the note A and the note D from the performance information, and the note ID is added from the object information to the performance information. By reading out the display data corresponding to "ID1" and performing display processing, a musical score in which the notes b and the notes c are decorated with choking symbols is displayed (step S65 in FIG. 8).

Next, as score editing, a decoration symbol (choking in this embodiment) is added to the score display shown in FIG.
Is input while pressing the "SHIFT" switch (that is, when YES is determined in step S61 of FIG. 8)
The music information editing process in will be described with reference to FIG. FIG. 12 is a conceptual diagram for explaining the music information editing process when the decoration symbol is input while pressing the “SHIFT” switch.

While pressing the "SHIFT" switch, similarly to the musical score display example shown in FIG. 11, among the musical notes A, B, C, and D displayed on the display device 6A, the musical note B (new musical note B in the figure) is displayed. When the score editing is performed so that choking is performed from the note B as the score display) to the note C (note C as a new score display in the figure)
The same score display information as that shown in 1 is created. That is, for the score display information, the display data “note b + cho (choking symbol) +” to which the identifier ID “ID1” is added as the first object of the object information
“Note c” is recorded in the order of creation (step S5 in FIG. 7).
9). In the decoration symbol ID list, the identifier ID “ID1”
Are recorded in the order of performance progress (step S60 in FIG. 7).
On the other hand, in the first track of the performance information, blank data is recorded instead of the data of “note B” and “note C” (FIG. 8).
Step S62). The blank data is the identifier ID “ID
It is data that does not include a performance event indicating that the performance event corresponding to the display data added with "1" is to be recorded. This blank data has an identifier ID
"ID1" is added. In this case, the musical score in which the notes b and the notes c are decorated with choking symbols is displayed, but even if the performance information is reproduced, the section corresponding to the blank data is not sounded. By directly inputting a performance event to such blank data, the user can perform the performance at the choking display position by his own performance. In the above embodiment, the note B and the note C are deleted from the performance information to record the blank data, but the present invention is not limited to this, and the note B and the note C are left when the blank data is recorded. The identifier ID "ID1" added to the blank data may be added to the performance event and recorded.

Next, as the score editing, the music information editing process in the case where another decoration symbol (trill in this embodiment) is input to the score display shown in FIG. 11 will be described with reference to FIG. FIG. 13 is a conceptual diagram for explaining the music information editing process when a decoration symbol is further input in a portion to which the decoration symbol is added.

As shown in the score display example of FIG. 13, from the note B displayed on the display device 6A (displayed as a note b as a new score display in the figure) to the note C (displayed as a note c as a new score display in the figure). (Display), choking is performed, and then score editing is performed so that the note b is trilled. Then, the performance event detected in step S51 of FIG. 7 corresponds to the first track created in FIG. Since it is reproduction data, YES is determined in step S54 in FIG. 7, and new object information is created from the object information created in the previous score editing process. That is, the display data “note b + tr (trill symbol) + cho (choking symbol) + note c” added with the identifier ID “ID2” as the second object of the object information (displayed by the dotted line in the score display example shown in the figure is performed. Data) is created and recorded based on the display data “note b + cho + note c” to which the identifier ID “ID1” is added (steps S56 and S in FIG. 7).
57). Therefore, the display data to which the identifier ID “ID2” is added includes the contents of the display data to which the identifier ID “ID1” is added. In the decoration symbol ID list of the first track ID list of the ID list information, only the latest identifier ID “ID2” among the identifier IDs is recorded. That is, the identifier ID of the object information used
Only record. On the other hand, no data is recorded on the master track of the performance information, but the reproduction data with the identifier ID "ID1" is deleted on the first track,
The newly created reproduction data with the identifier ID “ID2” is written at that position (step S6 in FIG. 8).
3). Of course, the identifier ID "ID2" is added to all the performance events included in the created reproduction data. Therefore, in this case, the note A and the note D are displayed by reading out each timing data of the note A and the note D and each note event from the performance information, and the display processing is performed, and the object information corresponds to the identifier ID “ID2”. The display data is read out and subjected to display processing to display a musical score in which the notes b and the notes c are decorated with choking symbols and trill symbols (step S6 in FIG. 8).
5).

Next, as music score editing, a music information editing process when a master independent symbol (allegro in this embodiment) is further input to the score display shown in FIG. 10 will be described with reference to FIG. FIG. 14 is a conceptual diagram for explaining the music information editing process when the master independent symbol is input.

As shown in the score display example of FIG. 14, when the score is edited so that Allegro is performed at the beginning of the section of the notes A to D displayed on the display device 6A, the score of FIG. If YES is determined in the step S8, the reproduction data corresponding to the master independent symbol is added without modifying the content of the performance information. That is, the display data “Allegro” to which the identifier ID “ID1” is added as the first object of the object information is added to the score display information.
(Data for performing display surrounded by a dotted line in the score display example shown in the figure) is recorded (step S4 in FIG. 6).
3). In the master track ID list of the ID list information, the same identifier ID “ID1” as that recorded as the first object of the above object information is recorded in the order of performance progress (step S44 in FIG. 6). On the other hand, reproduction data (tempo data in this case) corresponding to the added Allegro symbol without affecting the performance event is added to the master track of the performance information. At this time, if the tempo data is previously recorded at the position where the reproduction data of the master track of the performance information is added, the tempo data is deleted and the newly created data becomes valid. . Since no data is additionally recorded on the first track, the timing data of note A to note D and the note event data are still recorded in the order of performance progress. Therefore, in this case, note A to note D are displayed by reading out each timing data and note event from note A to note D from the performance information and display processing is performed, and the identifier ID “ID1” from the object information is displayed. By displaying the display data corresponding to and displaying the same, the score with the "Allegro" symbol is displayed (step S46 in FIG. 6).

Next, as music score editing, a music information editing process when an independent symbol (mezzo-forte in this embodiment) is further input to the score display shown in FIG. 10 will be described with reference to FIG. FIG. 15 is a conceptual diagram for explaining the music information editing process when an independent symbol is input.

As shown in the score display example of FIG. 15, note B among note A, note B, note C, and note D displayed on display device 6A (note B is shown as new score display in the figure) When the musical score is edited so that the mesoforte (mf) is added to, the answer is YES in step S8 of FIG.
It is determined that the reproduction data corresponding to the independent symbol is added without modifying the content of the performance information. That is, for the score display information, the display data “mf (meso / forte symbol)” (enclosed by a dotted line in the score display example shown in the figure, in which “ID1” is added as the identifier ID to the first object of the object information Data for displaying)
Is recorded (step S43 in FIG. 6). In the independent symbol ID list of the first track ID list of the ID list information, the same identifier ID "ID1" as that recorded as the first object of the above object information is recorded in the order of performance progress (step S44 in FIG. 6). On the other hand, reproduction data corresponding to the added meso / forte symbol is added to the first track of the performance information without affecting the performance event. In this embodiment, expression data corresponding to meso-forte (that is, volume data that affects only the corresponding track) is added between the data of “note A” and “note B”. Therefore, in this case, note A to note D are displayed by reading and processing each timing data and note event from note A to note D from the performance information, and the object information is changed to the identifier ID "ID1". By reading out and processing the corresponding display data, the score with "mf" is displayed (step S46 in FIG. 6).

Next, as the score editing, FIG. 1 shows the music information editing process when a decoration symbol (trill in this embodiment) is further input to the score display shown in FIG.
This will be described using 6. FIG. 16 is a conceptual diagram for explaining a music information editing process when a decoration symbol is further input to a portion to which an independent symbol has already been added.

As shown in the musical score display example of FIG. 16, for the note B already displayed with the meso-forte displayed on the display device 6A (in the figure, a new musical score is displayed as the note b), When the score is edited to perform the trill, a performance event corresponding to "note B" in FIG. 15 is detected in step S51 of FIG.
Since the D number is not added, NO is determined in step S54, and in step S55, the object information of the portion in which the decoration symbol is added to "note B" is newly created. In this case, the existing object information about the independent symbol is not modified. That is, the display data “note b + tr (trill symbol)” (data for performing the display surrounded by the one-dot chain line in the musical score display example shown in the figure) with the identifier ID “ID2” added as the second object of the object information It is newly created and recorded together with the first object (step S5 in FIG. 7).
9). That is, the display data "mf (meso / Forte symbol)" to which the identifier ID "ID1" is added is left. In the decoration symbol ID list of the first track ID list of the ID list information, the same identifier ID "I" newly recorded as the second object of the above object information is added.
"D2" is recorded in the order of performance progress (step S6 in FIG. 7).
0). On the other hand, the identifier ID “ID1” is recorded as it is in the independent symbol ID list of the first track ID list of the ID list information. That is, it does not affect the data of the independent symbols (meso-forte symbols) performed before adding the decorative symbol. On the other hand, for the performance information, the reproduction data corresponding to the added decoration symbol (trill symbol) is overwritten on the performance event at the position corresponding to the performance information. That is, in this embodiment, the reproduction data having the identifier ID “ID2” is overwritten and recorded at the position where the data of “note B” existed. Therefore, in this case, the note A, the note C, and the note D are read by processing the timing data of the note A, the note C, and the note D and the note events from the performance information to display the note A, the note C, and the note D. The display data corresponding to “ID1” is read out and processed to add the “mf” symbol, and the identifier ID “ID
The display data corresponding to "2" is read out and processed to display the musical score in which the note b is decorated with trill symbols (step S65 in FIG. 8).

The process of selectively writing the reproduction data and the blank data in the performance information (see FIG. 8) may be applied in the editing of the independent symbols. The format of the performance information generated by the “music information editing process” (see FIG. 4) described above is the “event + absolute time” format in which the event occurrence time is represented by the absolute time in the song or bar. "Event + relative time" format in which the time of occurrence of the event is expressed as the time from the previous event, and the "pitch (note) (Rest) + note length "format, a memory area for each minimum resolution of the performance, and a" solid method "format in which events are stored in the memory area corresponding to the time when the performance event occurs. It may be of such a format.

[0062]

According to the present invention, the score display information is stored only for the section displaying the complicated score, and the performance information is used for the section displaying the simple score to display the complicated score. Since the score is displayed by using the score display information for the section, it is possible to display the same clean score as the conventional one while reducing the amount of information required for the score display.
