Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an apparatus for creating TAB scores used for performances of stringed instruments and the like.

[Prior Art] Conventionally, T A B tt has been used as a musical score for playing stringed instruments such as guitars and basses. This TAB score is
It consists of the strings of a musical instrument and the fret numbers of these strings, and usually the player of the musical instrument would manually convert the standard music notation into TABM according to his or her own playing method.

[Problems to be Solved by the Invention] However, such conversion to TAB notation is troublesome, and some people who are not indignant may consider all the notes, chords, and keys of the sheet music to convert the corresponding musical instrument. It took a lot of time just to find the string and fret number that corresponded to the pitch.

An object of the present invention is to automatically perform conversion to TAB notation, which has conventionally been done entirely manually.

[Means for Solving the Problems] As a means for achieving the above object, the musical score editing device of the present invention, as illustrated in FIG. Musical score data input means MA for inputting musical score data, and musical score data T A B

That is, the musical score editing device first inputs the musical score data, the specifications of the corresponding musical instrument, and the conversion tendency set to reflect the player's preferences, playing method, and the like. Next, a TAB staff data table corresponding to the conversion tendency and musical score data is selected from the rAs = conversion table including one or more TAB staff data tables corresponding to notes, chords, or keys. Next, compare the selected TAB staff data table and the musical score data, and select the matching TAB staff data table.
Determines the score and outputs it as TABI. As a result, the TAB score output from the score editing device conforms to the score data and reflects the conversion tendency.

[Embodiment] Next, a personal score processor 1 (hereinafter simply referred to as PNP1) as an embodiment of the score editing device of the present invention will be described. The PNPI has the appearance shown in the perspective view of FIG.

It has code tables 44 for high and low, and a character generator (CG) 45.

The RAM 35 is for temporarily storing data, and here, in addition to a work area created when the control program is executed, a music score memory 51 that temporarily stores note data, symbol data, and staff data, which will be described later, and a print area. A print buffer 52 that temporarily stores data to be printed by the device 13
It has

The VRAM 37 stores data to be displayed on the display 9 in one-to-one correspondence with the display screen of the display 9. Note that in the block diagram of the electronic control device 15 shown in FIG.
The illustration of the interface section with the other devices is omitted.

Next, the processing performed by the electronic control unit 15 of PNPl is as follows.
Description will be made based on the flowchart of the main routine of this embodiment shown in FIG. 6 and the flowchart of the TAB conversion routine shown in FIG.

When the main routine shown in FIG. 6 is started upon power-on of the PNP1, initial settings of each part of the PNP1 and the electronic control unit 15 are first executed (step 100. Hereinafter, steps are simply referred to as S). After the initial settings, a process is performed to request input of new note data (S110).
An image as shown in FIG. 8 is displayed on the display 9. Note that the portions labeled 81 to S9 at the bottom of the image display the functions of the function key group 21. In response to a request for input of new note data (8th
This part is omitted in the image shown.

), when musical note data is input from the keyboard 3 or 7 or from the floppy disk device 11, the input musical note data is sequentially stored in the musical score memory 51 (S1
20). As shown in FIG. 5, the musical score memory 51 includes an area 60 for storing musical note data such as notes, rests, TAB notes, stroke notes, etc. that represent the sounds themselves input from the outside.
It is mainly composed of an area 61 for storing staff data indicating divisions such as one bar on a musical score, and an area 62 for storing symbol data including musical symbols, chord names, etc. The note data, staff data, and symbol data, detailed below, are integrated to form one musical score, so when the process of writing notes in the note data is performed, as shown in Figure 9, At the same time, the staff data and symbol data are updated.

As shown in FIG. 10, the musical note data consists of a flag indicating the type of data in the first byte and a subsequent data string. For example, if a value indicating a musical note is set in the flag, then there is data on the pitch and length,
If the flag is a rest, the note length, if the flag is a TAB note, the string number, etc.
Fret No. 9 and note length, and if it is a stroke note, there is pitch and note length.

Symbol data is processed in conjunction with musical notes, so the 11th
As shown in the figure, the first accompanying note's first note NO0
is required, and then there is the trailing note NO1.

Next, there are types of data and data strings to be attached to musical notes. As an example of the data type and data string, for example, in the case of code data, a flag indicating a code name is set as the data type, and code name data is set as the data string.

Staff data is used like an index for note data, including the number of total staves, page range, number of columns, number of bars, column range,
It consists of data strings such as bar ranges.

In the flowchart of FIG. 6, when the storage of note data in the score memory 51 is completed, it is then determined whether any key of the function key group 21 has been pressed,
If it is not pressed, input processing of musical note data (S110)
Return to (S130).

Here, if any key in the function key group 21 is pressed, it is then determined whether the pressed key is the key to start TAB conversion (3140).
, if it is another key, the process moves to another processing routine (not shown) such as editing processing or printing processing (S150).

If it is the key that starts the TAB conversion, then the first
By displaying the image shown in Figure 2 on the function display section of the function key on the display 9, processing is performed to request the operator to select a high code or a low code (S
160). With this, the conversion tendency when converting musical score data to TAB score is inputted. Therefore, the operator's playing method, preferences, instrument specifications, etc. will be reflected in the TAB score conversion process that will be performed later. Here, I will explain about high code and low code. When playing a chord (chord stroke) on a stringed instrument such as a guitar, there are generally two ways to press the string that corresponds to the chord (chord).
Exists as follows. For example, the chord "C" on the guitar
There are two ways to press the strings: a relatively low-pitched chord, as shown in FIG. 19, and a relatively high-temperature chord, shown in FIG. 22. When a high code or low code is input by the operator, it is then determined whether the input code is a high code or a low code (5170), and if it is a high code, it is stored in a predetermined area in the RAM 35. Please set the high flag indicating high code 3
180), if it is a low code, set the low flag (
S190). Next, the process shifts to the TAB conversion routine shown in FIG. 7 (S200).

In the TAB conversion routine shown in FIG.
The musical note data is sequentially read out, and the type of the read musical note data is determined (S210>).

For example, in the case of musical note data as shown in FIG. 10, the type is determined based on the flag content of the first byte.

Here, if the note data is a rest, as shown in the score in Figure 13, it is no different from a normal note, so the note data is moved to the next one without changing, or if it is a TAB note, it is already TAB. Since it has been converted into a musical note, the process moves directly to the next step (S220).

Next, note length data is directly attached to the migrated note data and stored in a predetermined area of the musical score memory 51 (S
230), Next, an image of rAs= is constructed based on the note data stored in the score memory 51 and the symbol data and staff data already stored in the score memory 51, and then the character generator 45 constructs an image of rAs=. Image data to be written to the VRAM 37 is created based on the character data, and processing for writing it to the VRAM 37 is performed (S240).
). As a result, the image data written to the VRAM 37 is displayed on the display 9.

For example, an image as shown in FIG. 13 is displayed on the display 9. That is, a normal musical score before conversion and a TAB score corresponding to this musical score are displayed. Here, the normal sheet music is already displayed, and this time T A B F
For example, only rests converted to a are newly displayed on the display 9. In other words, the first symbol data
rGLI ITARJ, rBAssj, rTA on Figure 3
BJ, etc., a single bar as staff data, and rests, notes, etc. of ordinary musical scores are already displayed.

After the image display process, it is then determined whether or not there is next note data and whether or not the end key has been pressed to determine whether or not to end this TAB conversion routine (S250 ＞.If you decide to end at this point,
Returning to step 110 in FIG. 6, if it is determined that the TAB conversion routine does not end, the process returns to the beginning of the TAB conversion routine and proceeds to the process of determining the type of the next note data.

In determining the type of note data, if it is determined that the read note data is, for example, a stroke note (the chord display is omitted here) as shown in the ordinary note in Fig. 14 (S210 ), then it is determined whether there is chord name data as shown in Figure 11 up to this stroke note or in the current measure (S
260>. As shown in Figure 14, a stroke note does not have any information about the pitch and only expresses the tamping of a chord stroke, so if a chord is not drawn, It is completely unknown whether he would play such a pitch.

Here, if it is determined that there is no chord name data, the stroke note should be changed to
Since it cannot be converted to an AB note, some kind of alarm is then expressed as an error (S270>. For example, a display as shown in FIG. 15 is displayed on the display 9, and a process is performed in which a chord name is input.

If it is determined that there was chord name data before in the stroke note processing (8260), then it is determined whether a high flag or a low flag is set (3280).

If the high flag is set, then the high code table stored in the code table 44 in the ROM 33 as shown in FIG. A pitch data string consisting of string-fret number data is read out and used as TAB note conversion data (3290). Note that the code table shown in FIG. 16 only shows a part of the code table. Further, the value corresponding to the first three bits (the number of bits in the binary code) of the hex code corresponds to the string number, and the value of the last four bits corresponds to the fret number. That is, based on the code number (code name data) attached to each code name, as shown in FIG. 17, in the code data address table, the storage address and code data corresponding to the code number are The data length is first read. Next, in the chord data string, the pitch data string stored between the data length and the storage address of the code data is read out. For example, if the code name is "C", as shown in FIG. 16, B3. A3,8
Read the pitch data strings of 5.65 and 45.23.

Once the TAB note conversion data is obtained, it is stored in a predetermined area of the score memory 51 (5230) and displayed (S24).
0), and determination of the end of the TAB conversion routine (S2
50) are performed sequentially. Accordingly, at the time of display, if a hexachord, for example, "B3" is stored in a predetermined area, 37 reds of the 6th string corresponding to this "B3" are displayed with a predetermined note length.

On the other hand, in determining whether the high flag or low flag is set (8280>, if it is determined that the low flag is set, then step 2
90, the low code table shown in FIG. 16 is searched and the TA corresponding to the previous code name data is searched.
Processing to obtain conversion data for the B note is performed (S300).

By the process of converting the stroke notes to TAB notes, the low chord "C" is expressed on the staff as shown in Figure 18, and the low chord "C" to be pressed as shown in the circle above TAB in Figure 19.
" is displayed like a TAB note on the TAB score in FIG. Also, in this case, every time a stroke note comes, T
AB notes are displayed, but instead of this, TAB the first stroke note of each measure, as shown in Figure 20.
It is also possible to convert the stroke notes to musical notes and display them, and to display the stroke notes as they are without converting them until the next chord transition or transition to the next measure. Note that the high code "C" as shown in FIGS. 21 and 22 is also converted using the same method as the low code,
Displayed as a TAB note.

Next, the process when the note data read from the musical score memory 51 in step 210 is a normal note will be explained. First, a search is made from the data string stored in the pitch table 42 in the ROM 33, as shown in FIG.
Read position data consisting of fret numbers (3
310).

Note that the pitch tape shown in FIG. 23 is only a partial example. For example, the musical note data is "C" shown in Fig. 24.
If it is "6" or "B1" two octaves above, then B4
．． Position data of AF, 8A, 65.41 is read out. This read position data is the 25th
This is shown in the figure (note that the 5.6 string is not filled in).

The position data of this hexachord is also the same as the hexachord in the chord table of FIG. 16, and is set in one-to-one correspondence with the string-fret number. For example, in the above position data, it is set as D4→6th string, 20th fret. At maximum, position data is output as many times as there are strings. For example, in the case of 6 strings, a maximum of 6 position data are output.

Although it is possible to output TAB note data by reading position data corresponding to the note data, in this state it is rare that the TAB note desired by the operator will be obtained. Therefore, we next determined the operator's preferences, playing method, etc.
A process for reflecting the conversion tendency, that is, a process for reflecting the conversion tendency, will be performed below.

As a process for reflecting the conversion tendency, it is first determined whether a high flag or a low flag is set (8320). If the high flag is set, the next preselected tonality (C major, A minor, etc.)
Read information about. For example, when C major is selected, the key table 43 in the ROM 33 contains, for example, the second key.
As shown in Figure 6, the stored C major high rough key table is read out, and the contents of this table are compared with the position data read out from the pitch table in Figure 23 to determine matching data (3330 ), Note that illustration of other key tables is necessarily omitted here. for example,
In the high coarse table of C major key, as shown in Figure 27,
The pitches on the musical staff are set, and correspond to the "high" positions as shown in FIG. 28. For example, the second
The rCJ in Figure 3 and the high rough adjustment table in Figure 26 match the 10 ruts of the 4th string.

On the other hand, if the low flag and C major are set, the second
The C major low rough key table shown in FIG. 6 is read out and compared with the position data read out from the pitch table shown in FIG. 23 to determine matching data (S340). For example, in the low rough key table for C major, pitches on the staff are set as shown in FIG. 29, and correspond to "low" positions as shown in FIG. 30. for example,
In "d" in Fig. 23 and the low coarse adjustment table in Fig. 26,
17 Lesotho on the 2nd string matches.

After comparing the key table in Figure 26 and the pitch table in Figure 23, it is next determined whether there is matching data (5350), and if there is matching data, it is
It is converted into musical note conversion data (3360). As a result, the TAB note at this matching position is displayed.

On the other hand, if there is no matching data as a result of comparing the key table in Figure 26 and the pitch table in Figure 23, then it is determined whether or not there is chord name data in the measure of the current note data. (S370). If there is chord name data, next read the pitch data string corresponding to this chord name data from the chord table shown in FIG.
The position data read from the pitch table shown in the figure is compared to determine matching data (S380). Here, if there is matching data (S390), a process is executed to use this as converted data (S360).

Also, by comparing the pitch data string and position data,
If there is no match, or if it was determined in step 370 that there was no previous code name data, then
Next, by the method shown below, conversion data is determined without using the chord table shown in FIG. 16 and the key table shown in FIG. 26 (S400), that is, the operator can select a high chord or a low chord. In order to reflect this in TAB conversion, if the high flag is set, the data closest to the 6th string will be selected from among the position data, and if the low flag is set, the data closest to the 1st string will be selected as the conversion data. Let be the converted data.

As described above, in normal TAB conversion of musical notes, a TAB score that reflects the operator's request can be output by selecting conversion data based on a high or low rough key table, a chord table, or a high or low mode.

In addition to the processing by this TAB conversion routine, as a correction function when the converted TAB note is different from the operator's intention, the converted TA
A process is added in which a TAB note on the B staff is indicated with a cursor on the display 9 and converted into a desired TAB note.

As described above, the PNPI of this embodiment can perform T A B conversion while reflecting the operator's playing method, preference, instrument specifications, etc., so TAB conversion is performed in a state close to the operator's intention. This has an extremely excellent effect of improving the efficiency of converting ordinary musical scores to TAB scores. Moreover, the data converted to the T A B score can be printed as is, and the efficiency of creating -rAB= from an ordinary musical score is improved.

Note that the present invention is not limited to the above embodiments,
Various embodiments can be implemented without changing the gist of the invention.

For example, in the embodiment, an example of TAB conversion of a guitar is given, but instead, any stringed instrument, that is, any musical instrument that has strings and frets that correspond to each other, may be used. Alternatively, the conversion data may be determined using only one of the key table and the chord table.

[Effects of the Invention] The musical score editing device of the present invention inputs musical score data and conversion trends, reflects the specifications of the instrument, the player's preferences, playing method, etc., and outputs a TAB score.

This allows the performer to perform the T.
This has the extremely excellent effect of being able to create AB scores almost automatically.

Furthermore, since the conversion to TAB score reflects the conversion tendency which is the intention of the operator, it is possible to output a TAB score that is very close to the intention of the operator. In other words, the efficiency of creating the T A B score is improved.
