Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for reconstructing a part or all of each page of an electronic work into a plurality of works by electronic processing and outputting the plurality of works, especially a score (score) used for an ensemble or the like. ) Input electronic data to create part data, which can be distributed through a communication network or printed on paper and output.

[0002]

2. Description of the Related Art Scores used for the performance of ensemble such as orchestral music, wind music, and duo are produced by composers using string instruments, wind instruments,
The music score of each part such as percussion instrument is a score that can be seen in parallel in time, called what is called a score, and conventionally, the transcription staff is the individual score for each part from the completed score. I used to write parts. For example, write out the parts for the violin part, the flute part, etc. separately from the orchestral score,
The musicians of each part receive the part score, and they practice and ensemble individually after seeing it.

This method has an advantage in that it is possible to find an easy-to-turn part for each part and make a page break, but there is a possibility that a copy error may occur because of manual labor.
There was a drawback that it took a long time for transcription. In particular, composers take time to complete their works, and the completion of the score is often delayed. As a result, there is a problem in that in order to be in time for the concert on the predetermined schedule, the copying staff is wrinkled, and it becomes necessary to pay an excess fee, and errors occur. In more extreme cases,
Sometimes the parts were too late to hold the concert. In addition, as a method of electronically creating a score, there are roughly two methods widely used. One of them is a method of inputting information of notes (length, height, strength, etc.) by numbers and converting them into musical scores by software processing. The other is a method of selecting each note or rest one by one from a list of notes with a pointing device such as a mouse and arranging them on a staff.

[0004]

However, in any of the methods, since the input is performed by a human, there is a problem in that an error occurs or it takes time, which is not much different from manual transcription. there were. In addition, the total score written by the composer may be photoengraved as it is and printed as a published score, but in this case, there is a problem that a part score cannot be created. Further, there are some inventions of a music score editing apparatus for digitizing and printing a music score (for example, JP-A-6-14).
9235, JP 6-149236 A, JP 7-129156 A, etc.). However, these devices aimed to correct some information and add information such as aligning multiple musical scores in the direction of time progression, moving staff in batches, and adding measure numbers. It was nothing more than a substitute for or support for the transcription business that creates parts from total scores.

In recent years, in the fields other than music, the printing industry has become electronic, and techniques such as printing by sending a published manuscript through a network and printing by digitizing an old manuscript have become common. As one of the specific examples, the fifteenth
The figure shows a block diagram of a general electronic publishing system. According to FIG. 15, when the customer brings a punch-stitched document to the printing company and requests it to print several tens of copies for education, the printing company scans the punch-stitched document.
The document is read from 1, and digitized by the document storage unit 32 and temporarily stored and stored. The purpose of digitization without copying is to prepare for repeat orders from the same customer.
This is to prevent the punched holes from being copied as black circles.

Therefore, the printer trades the computerized data (document data) of the original document stored in the document storage unit 32 with the edit processing unit 33 to perform the editing work for erasing the punch holes. At that time, since the punch holes are at different positions on the left page and the right page, it is determined whether or not there is a double-page spread. Then, if there is a double-page spread, the left-side page is erased from a fixed-size rectangular portion at the right edge of the page at several places (a few punch holes), and the right-page is a fixed-size rectangular portion at the left edge of the page. Is erased at several places (several punch holes). If there is no double-page spread,
The rectangular portion of the fixed size at the end portion of the document on the side where the punch holes are formed is erased at several places (the number of punch holes). When this editing process is completed for all pages, the print processing unit 3
4, the document data is read from the document storage unit 32, transferred to the printing apparatus, and printed on the paper by the required number of copies.

However, even with such a system, it is not possible at all to create a part score of each part from the above-mentioned total score. The present invention has been made in view of such a situation as described above, and it is possible to automatically create a part score of each part from a total score created by a composer, similar to the rewriting of a part by a copyist. West,
The purpose is to enable distribution to the performers of each part as needed.

[0008]

In order to achieve the above-mentioned object, the musical score editing apparatus according to the present invention is an electronic musical score in which musical scores of a plurality of parts are written in parallel as shown in a functional block diagram of FIG. Total score data input means A for inputting total score data which is data (electronic work), and editing means B for editing the total score data input by the means A into each part for each page and editing as the data of each part score. And output means C for outputting the data of each part edited by the editing means B.

The editing means B uses the character string (song name, chapter name, composer name, speed catchword,
And a means for adding the data of the character string extracted by the means to the data of each part obtained by dividing the first page into each part. Information such as the same song name, chapter name, composer name, speed slogan, and terminology indicating a musical idea can be written in the part score. Further, since the editing means B has a means for reconstructing each page by removing the extra blank of each page from the edited data of each part, the extra blank is eliminated, and it is easy to read and It can be a part with a lot of score information.

It is preferable that the means for reconstructing each page has a page break judging means for judging a musical score break for each part and for changing the page at the break. In addition, the page break determination means uses a specific character or symbol in the score of each part (a number indicating the number of rest measures, long rests, long notes, etc.)
Can be used as a means for recognizing, and recognizing a position where the recognized symbols continue for a predetermined number of times as a musical score delimiter, and changing the page. Alternatively, the page break determining means recognizes a plurality of predetermined types of characters or symbols (similar to the above) in the score of each part, determines a weight according to the type, and recognizes the recognized characters or symbols. The page break can be more appropriately performed by calculating with the number of continuations and the respective weights, and determining a position where the calculation result is equal to or more than a predetermined value as a score break to break the page.

Further, it is preferable that the page break determining means has a means for changing the weight depending on the types of the predetermined plural kinds of characters or symbols according to the tempo data described at the beginning of the score. In these musical score editing devices, the page break judging means has a validity judging means for judging one break and then the next break to judge which is a valid break position. Good. The validity determining means can be means for determining the longer break as a new page position within a range in which the score length from the previous page break is within one page. Alternatively, the validity determining means may be means for determining the one having the number of notes and rests from the previous page break closer to the preset number as valid.

In these musical score editing devices, the editing means B in FIG. 1 determines the length of the musical score from the break of the previous page break to the break of the next page break for each part.
By providing a scaling means for enlarging or reducing the score data of that page, it is possible to print the score of each page of the part score with an appropriate page break in a well-balanced and easy-to-see manner. Alternatively, the editing means B changes the designated size of the paper when outputting the data of the score of the page according to the length of the score from the break of the previous page break to the break of the next page break for each part. Means may be provided. It is preferable that the validity determining means has means for changing the validity criterion for an odd page and an even page.

In these score editing devices, the total score data input means A in FIG. 1 is a means for reading the total score with an image scanner and digitizing and inputting it, or a means for inputting the total score data through a network. Good. The output means C in FIG. 1 may be a means for distributing the data of each part edited by the editing means B through a network, or a means for printing on a paper and outputting each part. .

It is used as a memory area for storing the input score data and for storing the data of the created part music. The FDD 16 can insert a removable floppy disk, take in necessary information such as total score data from the floppy disk, and store the created part data in the floppy disk.

The CPU 11 controls the scanner 3 via the scanner I / F 3, causes the scanner 3 to read the information of the total score (score) and binarizes it, and staves and various characters, notes, rests, etc. The symbol or the like is recognized and digitized, input as total score data, and stored in the hard disk of the HDD 17. The digitization process of the musical score data is a known technique, and therefore its explanation is omitted. The CPU 11 creates part score data for each part from the input total score data by a process described later, and stores the data in the memory area of the HDD 17 for each part. By transferring the data of the part music to the printer 4 via the printer I / F 19 and printing it on paper, a paper part music is obtained. Alternatively, it is also possible to connect the NCU 20 to the communication network 5 shown in FIG. 2 and distribute the necessary part data to the personal computer owned by the performer of each part.

Next, various embodiments of the musical score editing process for creating the data of the part musical score of each part from the total musical score data by this musical score editing device will be described with reference to flowcharts and the like. In each of the embodiments described below, in order to make the description easy to understand, the total score 30 of the trio as shown in FIG.
Now, an example in the case of creating each part score of the three parts constituting the part will be described. There are many more parts in an actual orchestral score, etc., and the score on one page is often composed of a score with different parts, but the following example only changes the number of parts. Can be carried out similarly.

[First Embodiment: FIGS. 4 and 5] A first embodiment of the musical score editing process by the musical score editing apparatus shown in FIG. 3 will be described with reference to the flowchart shown in FIG. In the following description of the flowchart, the step is abbreviated as “S”. In this embodiment, the data of the total score 30 of the trio as shown in FIG. 4 is input and the part score of each part is created. In the total score of the trio, each page has a staff notation of three tiers of parts ,, and each stadium is a multiple of three. These are referred to as a first part, a second part, and a third part from the top. This score 30 is set on the scanner 3 shown in FIG.
When the process shown in (1) is started, the scanner 3 reads the information of the total score and digitizes it, and the scanner I stores it as total score data.
Enter in / F18.

The CPU 11 receives the total score data from the scanner 3 in S1, and stores the total score data for each page in the hard disk of the HDD 17 in S2. This is repeated until it is determined in S3 that the reception is completed. This total score data is input from the NCU 2 instead of being input from the scanner 3.
It is also possible to receive it from a terminal device such as another personal computer via the communication network by 0, or read it from the floppy disk storing the total score data by the FDD 16. After that, in order to create this total score data or the data of the drawn part score, unnecessary data is erased for each page. Therefore, in S4, the counter n is set to "1" and the maximum value n _max of n is set to "3". Each line has a staff notation, where n indicates that the created part is the nth part, and the maximum value n _max of n corresponds to the number of parts, that is, the number of lines of a set of staffs. In this example, since the total score data of the trio shown in FIG. 4 is edited,
Set as described above, first set n = 1, and start creating the part score of the first part.

In step S5, the total score for one page is read from the HDD 17 and temporarily stored in the RAM 13. And S6
Then, identify the staff lines in order from the top of the page. Then, in the next S7, data other than the n + n _max · m rows is erased. Here, m is 0 and a positive integer (m = 0, 1,
2, ...). Since n = 1 and n _max = 3 now, the data other than the 1st, 4th and 7th rows of the first part (the data of the 2nd and 3rd part rows) will be erased. The processes of S6 and S7 are repeated until it is determined in S8 that one page is finished. If it is determined that the page is finished in S8, S
In step 9, the data for one page is stored in the memory area for the n-th part (initially the first part) secured in the hard disk of the HDD 17. At this time, since only the score data of the first part remains, it is stored.

Thereafter, in S10, it is determined whether or not n = n _max . If No, in S11, n is incremented by 1 (n = 2), the processes from S5 to S8 are repeated, and S1 is set to 1
When it is judged that the page has ended, this time only the score data of the second part such as 2 lines, 5 lines, 8 lines, etc. remains, so that it is stored as data for 1 page in the memory area for the 2nd part in S9. To do. Then, in the determination of S10, n = n
_Since it is not _max , n is incremented by 1 in S11 (n = 3 is set), and similarly, the processes of S5 to S8 are repeated, and if it is determined in S8 that one page has ended, this time, 3 lines, 69 lines, 9 lines, etc. Since only the score data of the third part remains, it is stored as data for one page in the memory area for the third part in S9.

Then, in the determination of S10, this time n = n
_{Since max} = 3, the process proceeds to S12, where it is determined whether or not there is data for the next page. If there is data, the next page is specified in S13, n = 1 is set, and the process returns to S5, where the next page The total score data is read and the above operation is repeated. Then, the score data of the second page of each of the first part, the second part, and the third part is sequentially created, and the second page is sequentially stored in the memory areas for the first part, the second part, and the third part. Stores the data of. This process is repeated until n = n _max in S10 and it is determined in S12 that there is no data for the next page, and the score data of all pages of the total score is divided into each part as the data of each part. The data can be stored in the respective memory areas for the first part, the second part, and the third part of the hard disk.

When it is determined in S12 that there is no data for the next page, the process proceeds to S14, and the data for each part stored in each memory area is delivered or printed to be output. In the case of distribution, the NCU 20 of FIG. 3 is used to distribute to the terminal device designated in advance via the communication network 5 of FIG. For example, the part number data of each corresponding part is sequentially distributed to the personal computers 6, 7, and 8 owned by the performer of each part shown in FIG. Alternatively, each part score data may be converted into image data, and the image data may be transmitted to a designated facsimile machine. When printing, each part data is converted into image data for printing, transferred to the printer 4 shown in FIG. 3, and printed on paper. Such output processing is performed until it is determined in S15 of FIG. 5 that all parts have ended, and when the output of all parts ends, the processing of FIG. 5 ends.

By automatically creating each part by electronic processing from the total score created by the composer in this way, it is possible to eliminate a transcription error and to create an accurate part, and to manually copy the score. Because you do n’t have to spend time
It will save a lot of time. Moreover, if the data of the created parts is distributed to the terminal devices of the performers of each part via the network, the time and cost of mailing and carrying the completed parts will be saved, which will save time. Both in terms of cost and cost. In addition, in this embodiment, when creating each part by electronic processing from the total score data, data other than the part required for each page is deleted, but the present invention is not limited to this, and for example, for each page. It is also possible to extract only the data of the parts required for the above and store them sequentially in another memory or memory area.

[Second Embodiment: FIGS. 4 to 6] According to the first embodiment described above, it is possible to distribute or print the total score by dividing it into part music. It is easier to understand if the chapter name, composer name, etc. are entered. Also, in the case of a musical piece, a metronome symbol (for example, a quarter note symbol and a number that engraves it in one minute) that expresses the speed of the musical piece, a velocity slogan (Largo, Adigi)
o, Andante, Modelato, Allegr
o, Presto, etc.) and terminology (canta) that expresses the idea
bile, pastorale, elegante, g
(Labe, etc.) is added at the beginning and is usually written only in the top row of the score. In the score shown in FIG. 4, a title (song name) 31, a composer name 32, a speed slogan 33, and a metronome symbol 34 are described above the staff on the first line. Therefore, if the data is erased line by line as described above, such characters, symbols or slogans will be missing in the second and third parts. Therefore, in the second embodiment, when these characters and symbols are present at the beginning of the first page of the score, it is arranged on all the first pages of the part score divided into each part.

Most of the processing of the second embodiment is the same as the flow chart shown in FIG. 5 of the first embodiment, but part of it is changed as shown in FIG. That is,
The processing of S16 to S18 is added between S5 and S6 in FIG. That is, after reading the total score data for one page in S5, it is determined in S16 whether n = 1 and n = 1.
If it is not (first page), the process proceeds to S6 as it is to identify the line, but if n = 1 (first page), the process proceeds to S17, where the character (including the symbol) column before the first staff is identified. Data is extracted and temporarily stored. The extraction of this character string may automatically recognize each character and extract each position data and character (symbol) data of the character string, composer name, metronome symbol indicating tempo, speed catchword, etc. You may make it extract by designating a required part on a display screen. Then, in S18, a predetermined position in the memory area for each part (if the position data is stored, the stored position)
The data of the character (symbol) string of is stored and the process proceeds to S6.

[Third Embodiment: FIG. 5 and FIG. 7] The above-mentioned first embodiment
In the example, each score was created by leaving only the score of one part for each page from the score data and deleting the scores of the other parts, so the number of pages is the same as the score and the white space is The number of pages is increased during the performance, compared to the parts created by the conventional transcription companies.
There is a problem that it is difficult to play. In addition, the amount of data is large when electronically transmitting the created part data,
Another problem is that it takes time and costs. It is the third embodiment and the fourth embodiment to be described below that this point is improved so that a part without wasteful white space can be created.

The process of the third embodiment is almost the same as the flowchart of the first embodiment shown in FIG. 5, except that between S8 and S10, S9 is replaced with S21 shown in FIG.
And S22 are executed. That is, when it is determined in S8 that the processing of one page is completed, the space between the remaining staffs is removed in S21 to adjust it to a predetermined interval, and in S22, the n-th part (corresponding to the number of n at that time). The remaining data is stored in the memory area for the part), and when the area for one page is full, the rest is stored in the area for the next page. Then, the process proceeds to S10. By doing this, it is possible to eliminate the extra space and store the data of n times the total score (three times when there are 3 parts) in the one-page area of each part, and the number of pages is Since it becomes 1 / n, there is no useless data. Then, by printing the data, it is possible to obtain a part score that is easy to see and has a small number of page turns.

[Fourth Embodiment: FIG. 5 and FIG. 8] Next, another processing for eliminating an extra blank and creating a part music which is easy to see and has a small number of page turns will be described as a fourth embodiment. . This process is also the same as S1 to S6 and S14 to S15 in the flow chart shown in FIG. 5 of the first embodiment, but instead of S7 to S13, S23 to S23 shown in FIG.
S27 and S8, S10, and S11 to S also in the processing of FIG.
Execute 13. In this embodiment, a buffer memory having a capacity of one page for each part is prepared in advance, and row (staff) data is sequentially stored for each part in the buffer memory. As data for a page, the data is transferred and stored in a memory area for storing data of parts for each part. Do this from the first part to the third
Repeat up to the part, and create three kinds of new works, part music.

This processing will be described with reference to the flowchart of FIG. In S5, the total score data for one page is read out,
When the staff line is identified in S6, the row is n + in S23.
It is determined whether or not n _max · m rows (m = 0, 1, 2, ...). The n and m are the same as defined in the first embodiment. If so, go to S24 and set the data in that row to 1
Store in the page buffer memory, and if not, proceed directly to S8. After S24, in S25, it is determined whether or not the data stored in the buffer memory is full. If not, the process proceeds to S8, but when full, the process proceeds to S26, where the buffer memory of the n-th part is stored in the buffer memory. After storing the data as one page, the process proceeds to S8.

In S8, it is determined whether or not one page has been completed (processing of the total score data for one page has been completed). If not completed, the process returns to S6, the next staff is identified, and the above-described processing is performed. repeat. If it has ended, the process proceeds to S12 to determine whether there is a next page, and if there is, the next page is designated in S13 and the process returns to S5 to read the total score data for the next one page and perform the above process. repeat. When the next page is exhausted in the determination of S8, the process proceeds to S28, and if there is data in the buffer memory, it is transferred to the memory area for the nth part and stored as the data of the final page. Then
In S10, it is determined whether or not n = n _max . If not, the process proceeds to S11 to increment n by 1. Then, in S27, the first page is designated and the process returns to S5, and in order to create the part score data of the next part, the total score data for the first page is read and the above-described processing is repeated. When this process is repeated and n = n _max in S10, it means that the part score creating process for all the parts has been completed.
The process proceeds to 14 to deliver the data for each part (part number data) to a predetermined terminal device via the communication network 5, or print it on paper by the printer 4 and output it.

[Fifth Embodiment: FIG. 8 and FIG. 9] In the above-described third embodiment, extra spaces between staffs are removed to adjust the intervals between staffs and store them in the memory area for each part. The page break is defined when the area for one page is full, and the page break is defined when the buffer memory for one page is full in the fourth embodiment. Can be difficult to do. For example, if a page break occurs at a fast tempo and a sequence of relatively short notes in time, it becomes difficult to turn pages. This will be improved in each of the embodiments described below. First, in the fifth embodiment, S31 and S32 shown in FIG. 9 are added between S24, S25 and S26 in the flowchart of FIG. 8 of the fourth embodiment.

That is, after the data of the row is stored in the buffer memory for one page in S24, a process for determining whether or not a page break should be performed in S31, and in S32, it is determined and a page break is performed. If so, the process proceeds to S26 at that point, and the data in the buffer memory is stored as one page in the memory area for the nth part. When it is determined in S32 that the page is not changed, it is determined in S25 whether or not the data stored in the buffer memory is full. If the data is full, the process proceeds to S26, and the data in the buffer memory is set to 1 in the memory area for the nth part. Store as pages. If it is not full, the process directly proceeds to S8 of FIG. 8 and the subsequent processes are performed. After performing the process of S26, the process proceeds to S8 of FIG. 8 and the subsequent processes are performed.

Note that it is determined in S32 that a line feed will occur, and S26
If it advances to, it is judged that the line is to be broken on the last line, so the data after it is judged that the line should be broken on the last line is stored in the memory area for the nth part up to that point in the buffer memory. After storing the data of 1 page as one page, a page break mark may be put and stored at the beginning of the next page. In the case of this embodiment, whether or not a page break is to be made is determined by the electronic processing of this device in the same manner as in the next embodiment, by the type and continuation of a specific character or symbol (including rests and notes). Although it can be automatically judged from the number,
As a simple method, each time the data of each row is stored in the buffer memory, it is displayed on the display, and whether or not a page break should occur, and in the case of a page break, the position, the pointing device, etc. Alternatively, the determination may be made based on the presence or absence of the input.

[Sixth Embodiment: FIG. 8, FIG. 10 to FIG. 12] In this sixth embodiment, it is automatically determined by electronic processing whether or not a page break should be made in the fifth embodiment. It is an example of The processing of this embodiment also has many parts in common with FIG. 5 and FIG. 8, and therefore description thereof will be omitted. In this 6th Example, it replaces with S25-S26 of the flowchart shown in FIG. 8, and S33-S4 shown in FIG.
0 and the processing of S26 'is performed. That is, after storing the data of the row in the buffer memory for one page in S24,
In S33, the counter N is reset and started. This counter is a counter that counts the number of consecutive specific rests or notes.

At the next step S34, characters or symbols are sequentially identified in the row direction from the beginning of the row stored last in the buffer memory. The letters or symbols include notes and rests as shown in FIG. 11 and numbers (indicating the number of bars at rest) written above the mark for resting the entire bar as shown in FIG. As described above, the processing of sequentially slicing and recognizing characters and symbols on the staff notation, that is, notes and rests, is known, and is disclosed in, for example, JP-A-6-102868, JP-A-6-102869, and JP-A-6-102870. Since it is described in the official gazette and Japanese Patent Laid-Open No. 6-102871, its explanation is omitted.

Then, it is determined whether or not the identified character or symbol is a specific character or symbol designated in advance (S35).
To judge. The specific character or symbol is, for example, as shown in FIG.
It is assumed that the whole bar shown in FIG. 2 is a number written on the mark for resting, a half rest or a whole rest (specific rest) shown in FIG. 11, or a half note or whole note (specific note). If they are these specific characters or symbols, the counter N is incremented by 1 in S36 to count them. Then, in S37, the count value N becomes equal to or more than the preset value Ns (N
≧ Ns). If not, it is determined in S40 whether it is the end of the line. If not, the process returns to S34 to identify the next character or symbol and repeat the same processing. If it is the end of the line, the page break determination process for this line is complete.
The process proceeds to S8 shown in FIG. 8 to determine whether or not one page has ended.

If it is determined in S35 that it is not a specific character or symbol, the counter is reset in S39, and it is determined in S40 whether it is the end of line. If it is not the end of the line, the process returns to S34 to identify the next character or symbol and repeat the same processing. If it is the end of the line, the page break determination process for this line has been completed, so the process proceeds to S8 shown in FIG. When N ≧ Ns in S37, the process proceeds to S38, it is determined that the page is changed at the end of the bar, and the subsequent data is saved separately. Then, in S26 ', the data of the puffer memory is stored as one page in the memory area of the nth part, and the separately saved data is stored as the first data of the next page. After that, the process proceeds to S8 shown in FIG. 8 to determine whether or not one page has ended.

The count of a specific character or symbol is divided according to the type, for example, a number of rest measures, a long rest or a long note, and the number of consecutive specific characters or symbols of the same type is counted. It is desirable to do so. Then, as a measure of Ns, when there is a rest or pause of one measure or more or a note of the same length, a page break is made at the end of the measure, and the rest of the line is written to the next page. To do so.

[Seventh Embodiment: FIG. 8, FIG. 11 to FIG. 13] According to the above-described sixth embodiment, when the suitability of a page break is judged by, for example, a rest or a series of notes having the same pitch, a rest is applied. Alternatively, the time length differs depending on the type of note, and even if the same number of rests or notes continues for a predetermined number of times, the total time length varies depending on the type. Although not often used in part music, in the case of general music, in order to make it easier to understand the relationship with other parts, short rests may be consecutive to represent long rests. In such a case, even if a long rest is searched for, a long rest may not be found.
In the seventh embodiment, such a problem is solved and the page is changed when there is a sufficient break for turning the page during the actual performance.

FIG. 13 is a flow chart showing the process of the seventh embodiment which replaces the process of the flow chart shown in FIG. 10 of the sixth embodiment. In FIG. 13, steps of the same processing as those in FIG. 10 are indicated by the same step numbers, and similar but slightly different steps are indicated by the same step numbers with a dash. In this embodiment, after the data of that row is stored in the buffer memory for one page in S24 of FIG. 8, the four counters Na to Nd are reset and started in S33 'of FIG. The counters Na to Nd are counters for individually counting 8th rests, 4th rests, 2nd rests, and all rests that are designated as specific rests in advance.

In the next step S34, characters or symbols are sequentially identified in the row direction from the beginning of the last line stored in the buffer memory. Then, it is determined in S35 'whether or not the identified character or symbol is one of the specific rests designated in advance. If it is not a specific rest, all counters Na to Nd are reset in S39 ', and it is determined in S40 whether it is the end of line. If it is not the end of line, the process returns to S34 and the next character or symbol in the line direction. Is repeated and the determination of S35 'is repeated. If it is the end of the line, the page break determination process for this line has been completed, so the process proceeds to S8 shown in FIG. If it is determined in S35 'that the rest is a specific rest, one of S41 to S44 is selected depending on the type of rest (8th rest, 4th rest, 2nd rest, or all rests). The corresponding counter among the counters Na to Nd is incremented by +1.

Then, in S45, the respective rests are set as shown in FIG.
The total sum ΣN obtained by weighting and adding the count values
Is calculated by the following formula. ΣN = Na + 2Nb + 4Nc + 8Nd Then, in S46, it is determined whether or not the total sum ΣN is equal to or more than a preset value Nk (ΣN ≧ Nk). Returning to S34, the next character or symbol in the row direction is identified,
The above process is repeated. If it is the end of the line, the page break determination process for this line has been completed, so the process proceeds to S8 shown in FIG.

When ΣN ≧ Nk in the judgment of S46, S3
Go to 8 and decide that the page will be changed at the end of that measure,
Save the subsequent data separately. Then, in S26 ', the data in the puffer memory is set to 1 in the memory area of the nth part.
The data for each page is stored, and the separately saved data is stored as the first data for the next page. After that, the process proceeds to S8 shown in FIG. 8 to determine whether or not one page has ended. As an example of calculating the sum ΣN in S45, for example, when one quarter rest and one half rest, and one quarter rest are arranged in succession, Nb = 2 and Nc = 1 are set. Therefore, ΣN = 2Nb +
8Nc = 2 × 2 + 4 × 1 = 8. If the time signature is 4/4, this is one bar, so if one bar is considered as the predetermined rest length for page breaks, Nk = 8 should be set. An optimum value can be adopted as a threshold Nk of a rest length for judging whether or not each rest is weighted and whether or not a page break is appropriate.

As a specific character or symbol, FIG.
When the number indicating the number of consecutive bars shown in FIG. 11 is also adopted, the weight is set in accordance with the weighting of the rests in FIG. 11, and when the number is N, it may be 8 × N. . Therefore, as shown in FIG. 12, when the numbers are 2, 4 and 8, the weights are 16, 32 and 64, respectively.
become. Therefore, if Nk = 8 is set as in the above-described example, if there is one number, it is determined that the page will be changed regardless of the number. Alternatively, instead of rests, the number of consecutive notes with the same pitch may be counted, and a page break may be performed even when the total length reaches a predetermined value. The determination of S35 'in 13 is set as a specific note, which is used in S41-
In S44, the number of each note is counted, and in S45, each note shown in FIG. 11 is weighted to calculate the total sum ΣN, and when the value becomes equal to or more than the preset value Nk, it may be determined that the page breaks.

Judgment based on the specific rest sequence described above,
Judgment based on the presence / absence of a number indicating the number of pauses is used together with judgment based on the presence / absence of a number indicating the number of pauses, and determination based on the continuation of specific notes of the same pitch. It is also possible to give top priority to the judgment based on the continuation of, and finally adopt the judgment based on the continuation of a specific note having the same pitch to break the page. If you don't have long rests,
Since you can play the same note for a long time, or where there are a series of easy-to-remember notes that slowly change in scale, you can play without reading the score during that time, so you can break the page. .

Here, it is more preferable to consider the second weight by the numerical value designated by the metronome symbol 34 described at the beginning of the score 30 shown in FIG. For example, when the number of beats of quarter notes by the metronome symbol is M, the value of ΣN calculated in S45 of FIG.
By multiplying by (60 / M) × ΣN, it is possible to obtain the actual break time. For example, when the metronome symbol described in the total score is quarter note = 120, in the case of ΣN = 2 × 2 + 4 × 1 = 8 in the above example, (60 / M) × ΣN = (60/120) × 8 = 4, which means that there is about 4 seconds of rest. Therefore, it is advisable to specify 5 seconds or 10 seconds as the threshold value for determining whether the page break is appropriate.

[Eighth Embodiment: FIG. 14] In the fifth to seventh embodiments, it is decided whether or not the page break is appropriate and the page break is performed, and the part score data for each page of each part is stored in the memory area of each part. However, it is not always optimal, and there are cases where there are too many page breaks or there are other more appropriate page break positions. Therefore, in this embodiment, a page break correction process is performed to check the page data once created and check the page break, and if there is a more appropriate page break position, change the page break position. is there.

FIG. 14 is a flow chart showing an outline of the page break correction process. First, in S51, the page break (break) of the data stored in the memory area for the part
Check the position by searching for the two positions from the beginning. Then, in S52, it is determined whether or not there is a page break position (page break symbol) in the data that fits in the storage capacity of one page. If not, in S57 a page break mark is placed at the end position of the storage capacity of one page. And returns to the main routine shown in FIG. If there is a page break position in the determination of S52, the process proceeds to S53, it is judged whether or not there are two places, and if there are no two places, one found page break position is maintained as it is and the process returns. If there are two places, it is determined in S54 which of the preceding and following page break positions is appropriate. If the former is judged to be appropriate, the subsequent page break symbol is deleted in S56 and the latter is considered appropriate. When it is determined, the previous page break symbol is deleted in S55, and the process returns to S51.
The above process is repeated. Thereby, if there is an appropriate page break position after that, the page break position is changed.

An example of a method for judging the appropriateness of the page break (break) position will be described. For example, it is added to the judgment condition that as many musical score data as possible fit in one page of the part score and that the musical score data does not overflow. This is the same as the parts with a large number of notes and rests and the parts with a small number of notes in the total score, but it is better to keep the number of notes and rests constant when creating parts. This is because it is easier to read by arranging a large number of notes and rests by reducing the size of the bar, rather than arranging a number of large bars each containing only one rest. Therefore, for example, a rough number of notes and rests to be stored in one page is determined in advance, and the number of notes and rests on one page is closer to the determined number and exceeds the storage capacity for one page. Judge that the page break position where there is no one is more appropriate.

Further, the page break position where the number of notes and rests on one page is closer to the determined number, or when there is only one page break position, the page break position is
If the storage capacity for one page is too small or too large, another process may be added. For example,
When the score amount up to the selected page break position is larger than the storage capacity of one page, the score data may be reduced so that the score data fits in one page. On the other hand, if the score amount up to the selected page break position is too small than the storage capacity for one page, the score data may be enlarged so that the score data will be substantially full for one page. This makes it possible to create well-balanced and easy-to-read parts.

In such a case, instead of changing the size of the musical score, the designated size of the paper for printing may be changed. For example, when creating a B5 size part, the length of the score from the page break position to the next page break position may not fit on one page of B5 size paper. At this time, the designated size of the printing paper is changed from B5 to B4 for printing. When using a large sheet of paper, it is not unnatural if the score is changed in the middle of the page.

Further, when judging the validity of a page break,
When creating a two-page spread part, it is better to change the judgment criterion of the adequacy of the page break judgment between the odd page and the even page. To be more specific, when two pages are displayed in a spread, an even page is displayed on the left side, and an odd page is displayed on the right side, the transition from the even page to the odd page does not turn over the page, so it does not require much time, On the other hand, it takes time to move from an odd page to an even page because it involves page turning. Therefore, the threshold for determining a page break may be changed depending on whether the currently created page is an odd page or an even page. In this case, it is preferable that the threshold value for the odd page is made larger than the value for the even page.

In the inventions of all the embodiments described above, the total score data input from the scanner as electronic data or sent through the communication network is input, and divided into part score data and edited. Then, an example has been described in which it is printed on paper by a printer and output, or it is delivered to a predetermined terminal device via a communication network. However, the created part data is converted into image data and transferred to a facsimile, or a floppy disk or CD-
It can also be output to a storage medium such as a ROM and mailed or handed to the performer.

In the description so far, it has been described that a part score is made from a total score and distributed to each musician, but the distribution destination is not limited to the musician as long as he / she needs it. In some cases, all parts may be sent to one person. Further, the present invention can be applied not only to creating a part score from a total score, but also to creating a secondary work from other electronic works.

[0058]

As described above, by using the musical score editing apparatus according to the present invention, a part score of each part similar to that rewritten by a copyist as a part score can be created from the total score created by the composer. Since it can be created automatically, the time and cost required for transcription can be reduced. Further, it is possible to distribute the created part score data to the performers of each part through a communication network as needed, thereby further saving time and cost. As a result, even if the composer slightly delays the completion of the work, the influence on the creation of the part score is reduced. In addition, there are many advantages such as being able to create accurate parts without writing mistakes.
