[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a music information display system and, more particularly, to a music information display system for performing music in accordance with displayed music information.

[0002]

2. Description of the Related Art Conventionally, to display such music information, graphic patterns of various music symbols are displayed in icons at an edge of a display screen, and the same music symbol as the graphic pattern is selected. There are things that create music scores. The graphic pattern of the musical symbol includes a staff, a musical note symbol, a rest symbol, a key signature, an accidental symbol, a time signature, a dynamic symbol, a speed symbol, and the like.

In the selection, for example, a cursor corresponding to the movement of the mouse is displayed on the display screen, and the mouse is moved to move the cursor to the icon of the graphic pattern to be displayed, and the click button of the mouse is turned on. Thereby, the graphic pattern of the music symbol to be displayed is selected. Next, the cursor is moved to a position to be displayed on the display screen, and the click button of the mouse is turned on again. As a result, the graphic pattern of the music symbol is displayed at the position to be displayed. In this case, the mouse cursor changes to the graphic pattern of the selected music symbol when the first click button is turned on. By repeating such operations, a musical score can be created and displayed on the display screen.

[0004]

However, such a musical score display device merely displays a musical score, and it is not possible to confirm as a musical tone what kind of music the created musical score will actually be. Did not. In particular, it is very effective in music education to actually confirm a created musical score as a musical tone in a music teaching tool.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a music information display system capable of automatically performing a performance according to a displayed musical score and actually confirming the displayed musical score by ear. It is intended to provide.

In the conventional music information display system described above, the staff length is fixed, the display position is also fixed, and any length and any display are possible. The position could not be selected. The clef is also displayed together with the staff display, and it was not possible to create an arbitrary score. The present invention also solves such a problem.

[0007]

In order to achieve the above object, according to the present invention, displayed music symbol information is sequentially searched, and the music symbol information is arranged in order from the beginning of a musical score to create performance information. It is like that. Also, various music symbol information is entered for each display part of the display means, and a graphic pattern corresponding to the music symbol information is displayed over a plurality of display parts.

[0008]

According to the present invention, not only the musical score can be displayed, but also the performance corresponding to the displayed musical score can be heard by ear, which is very effective in composition or music education. In addition, each music symbol can be input and displayed at an arbitrary entry point. For music symbols such as staffs, the length can be arbitrarily specified.
It can be input and displayed separately from the staff, and any score can be created.

[0009]

[Examples] 1. Display Screen 20 FIG. 1 shows a display screen 20 of a CRT (CRT) 5. On the left side of the display screen 20, a symbol icon 22 of a musical symbol such as a musical note (rest) or a staff is displayed. At the place corresponding to the desired music symbol of the symbol icon 22, the cursor 25 of the mouse 1 is overlaid and the left click button 1a of the mouse 1 is pressed, whereby a desired music symbol can be selected. After this selection, the cursor 2 of the mouse 1
By moving the mouse 5 into the viewport 21 and pressing the left click button 1a of the mouse 1, the graphic pattern 26 of the music symbol can be displayed at a desired entry point. The CRT 5 may be replaced with a liquid crystal display, a plasma display, or the like.

On the upper side of the display screen 20, command icons 23 for commands such as performance, sound, and file are displayed. A desired command process can be selected by placing the cursor 25 of the mouse 1 and pressing the left click button 1a of the mouse 1 at a position corresponding to the desired command of the command icon 23. Most of the display screen 20 is a viewport 21 and the viewport 2
1, a graphic pattern 26 of the created musical score is displayed.

FIG. 2 shows an example of a graphic pattern 26 of a musical score displayed in the viewport 21.
The viewport 21 is divided into a display part 27 of 3 bits × 5 bits and so on.
The graphic pattern 26 of the music symbol for each unit
Entry is made.

However, the graphic pattern 26 of each music symbol is displayed over a plurality of display parts 27 as shown in FIG. Therefore, for the graphic pattern 26 of each music symbol, a display entry point 24 indicating the entry point is created.
Display part 2 to which this display entry point 24 belongs
7 are entry points of the graphic pattern 26 of music symbols.

The symbol icon 22 includes, in order from the top,
Note (rest) symbol, staff symbol, clef, ensemble concatenation symbol, key signature, vertical bar, accidental symbol, repeat symbol, time signature, tie (slur) / crescendo (decrescendo) / bracket, dynamic symbol Graphic patterns 26 such as, articulation symbols, playing style symbols, speed symbols, hooks (note digits), lyrics, tuplets, free graphics, etc.
Is displayed. The music symbol changes cyclically each time the cursor 25 of the mouse 1 is changed to a music symbol, moved into the viewport 21, and the right-click button 1b of the mouse 1 is pressed.

For example, for a note (rest), upward 4
Quarter note → quarter note down → quarter rest → quarter note upward →
… Or whole note → half note → quarter note → eighth note → 16
It changes cyclically in the order of 1 / 32th note → 2nd note →. In this case, operating the numerical key of "1" on the keyboard 3 adds one dot, and operating the numerical key of "2" adds two dots. In the case of a staff symbol, the circulation changes in the order of five-line type → one-line type →. For clef, G clef → F clef → C clef → G clef →
It changes cyclically. In the case of a time signature, the value of the denominator of the time signature and the value of the numerator are cyclically changed. In this case, the cyclic change of the numerical value of the numerator is executed by pressing the right-click button 1b after determining the numerical value of the denominator by operating the left-click button 1a. The information of this molecule is stored as additional information of the time signature.

In the accidental symbols, for example, the cycle changes from sharp to flat to natural to sharp to. The key signature is almost the same. In the case of dynamic symbols, for example, Forttesimo f
f → forte f →... → pianissimo pp → forttesimo ff →. In addition, other fortissimoassay fff or more, pianissimoassay pp
p or less, Diminuendo dim. Etc. may be included. The speed symbol is input by a numeric key on the keyboard 3.
The entry of these music symbols may be performed by any other method, such as selecting and displaying each music symbol in a window, or inputting from the keyboard 3.

[0016] Here, the beginning and end, such as a staff, an ensemble connection symbol for connecting the staff, a tie (slur) / crescendo (decrescendo) / bracket symbol, a chain hook (note digit) symbol, and a tuplet symbol. Is required to operate the left click button 1a of the mouse 1 at the head position, and then operate the left click button 1a of the mouse 1 at the end position to determine the length of the music symbol. In this case, the display entry point 24 of these music symbols is not at the end position but at the head position, and the length data of this music symbol is stored at the head position.

When the cursor 25 is moved downward after designating the head and length of the staff, a plurality of staffs are sequentially displayed according to the movement interval. The plurality of staffs are each a vertical dimension d + e + f of a staff area 29 described later.
It is displayed for each. The length of each staff is unified to the length already specified above. In this case, cursor 2
When the right-click button 1b of the mouse 1 is turned on while the user 5 is moving downward, the type of staff displayed sequentially is changed. Note that the designation of the plurality of staffs may be such that, after designating the head, the cursor 25 is moved to the lower right, and the staff length and the number of staffs are designated at one time. A plurality of staffs created simultaneously in this way are simultaneously played in parallel.

As shown in FIG. 2, one staff is created and displayed in correspondence with one row of the display parts 27. Also, one space (space), additional line (leisure line), and additional line (leisure space) of each line of the staff are created and displayed corresponding to one line of the display parts 27. This is for making each line of the display parts 27... Correspond to the pitch of the note symbol in the staff in one-to-one correspondence.

When the cursor 25 of the same music symbol is overlaid on the graphic pattern 26 of the music symbol displayed in the viewport 21 and the left click button 1a of the mouse 1 is turned on, the displayed music symbol is displayed. The graphic pattern 26 is deleted. When the cursor 25 of the musical note symbol is slid below the first line or above the fifth line of the staff, a line corresponding to the slide interval is automatically added and displayed. This line is added to the musical notation cursor 25 by the staff area 29 shown in FIG.
It is added and displayed until it goes outside. Further, when a vertical line indicating a bar break is entered in the ensemble-type staff, the vertical line is automatically entered at the same position as the other staffs.

On the command icon 23, graphic patterns 26 of commands of delete, range designation, help, new, file, delete, enlarge, play, print, environment, sound, and end are displayed in order from the left. The deletion is to specify and delete each of the graphic patterns 26 of the displayed music symbols. The range designation is to designate an area in the viewport 21 to delete, move, or enlarge data in the area.

The file is to save the display data and performance data of the musical score created in the viewport 21 to the floppy disk 7 or to load the data from the floppy disk 7. The erasing is to erase the graphic pattern 26 of the displayed music symbol by designating a range. The enlargement is to enlarge and display the graphic pattern 26 such as a musical score created in the viewport 21. The performance is to automatically perform the graphic pattern 26 of the musical score created and displayed in the viewport 21.

Printing means printing out a graphic pattern 26 such as a musical score created in the viewport 21. The environment is to set the tempo, volume, display scale, and the like of the automatic performance. The sound is to designate the tone color of the musical score created in the viewport 21. When a plurality of musical scores are drawn in the ensemble format, the tone color is designated for each performance part. The performance part refers to performance of a melody, chord, rhythm, MIDI (musical instrument digital interface) external input, and the like.

The staff number register 140 stores staff number data SN. The staff number data SN indicates the order of a plurality of staffs displayed in the viewport 21. The timbre register 141 stores timbre data for each performance part set by the command icon 23 of the sound. The tempo buffer 142 stores tempo data, and the tempo data used is the tempo set by the command icon 23 in the above environment or the tempo data displayed on the score in the viewport 21.

The RAM 13 also stores graphic data GF corresponding to the music symbol code data KD, character data corresponding to character codes, and the like.
The music symbol code data KD is converted into such graphic data and the like, written into the graphic memory 6, and the graphic pattern 26 such as music symbols and characters is displayed on the CRT 5. Further, the RAM 13 stores C to execute various processes shown in a flowchart described later.
A program executed by the PU 11 is stored.

The graphic data of the symbol icon 22 and the command icon 23 are also written in the graphic memory 6 and displayed on the CRT 5. The above-described programs and data stored in the RAM 13 are originally stored in the floppy disk 7, read out through the floppy disk driver 8, and transferred to the RAM 13, or conversely read out from the RAM 13 and stored in the floppy disk 7. Or This floppy disk 7 may be replaced by another storage means such as an optical memory and a memory card. The ROM 12 stores programs and the like executed by the CPU 11 for performing various processes and other processes shown in a flowchart, which will be described later. The contents stored in the graphic memory 6 are read by the CPU 11 and printed by the printer 9 through the print driver 10.

The tone generator 14 shown in FIG. 3 generates a tone signal corresponding to the pitch, timbre, tone length, velocity, etc., according to the performance data MP in the performance memory 133.
It is sent to the sound system 15 and is pronounced. The tone generator 14 is provided for a plurality of channels, for example, 16 channels.
A tone generation system for channels is formed by time-division processing, and a tone can be generated polyphonically. Data relating to musical sounds assigned to each channel is stored in an assignment memory (not shown). Note that the tone generator 14 and the sound system 15 may be provided via a MIDI interface (not shown), or the sound generation may be performed on performance data input via another MIDI interface. .

[0035] 3. Data Format Figure 5 shows the code data KD of musical symbols stored in the display code memory 131, FIG. 6 shows performance data MP is stored in the play memory 133 converts the code data KD of musical symbols . Music symbol chord data K
D is composed of content data of each music symbol, an additional code, and the like. The content data indicates the content of a musical symbol, for example, a blank, a clef treble clef, a bass clef, a c-clef..., An upward quarter note, a downward quarter note, a quarter rest. Type, accidental sharp, flat, natural ..., time signature denominator value, dynamics symbol fortessemo f
f, forte f ..., pianissimo pp ..., each of the ensemble concatenation symbols, each of the vertical lines, each of the repetition symbols, ties, crescendos, decrescendos, parentheses, each of the articulation symbols, each of the performance symbols, each of the speed symbols Values, etc. are shown.

The additional code is composed of the above content data only.
When the content of the music symbol cannot be represented, an additional flag bit is set. For example, in the case of a musical note, the presence / absence of overlap with another music symbol, the presence / absence of a line, the presence / absence of forming a chord, the presence / absence of a hook (note digit), the presence / absence of a tuplet, etc. In addition, if it is a time signature, the presence or absence of the numerator of the time signature, the presence or absence of length data such as staff, tie, crescendo, decrescendo, the creation order of each staff, the presence or absence of a connected staff, the beginning of the connection staff Or not. Based on the additional code, additional data described below is stored in the display code memory 13.
1 is stored.

As the additional data, the value of the numerator of the time signature, length data of staff, tie, crescendo, decrescendo, etc. are stored. In addition, in the case of the above-mentioned hook (sign digit), the type data of the hook and the position data of the hook are stored as additional data. The type data of the hooks indicate the number and shape of the hooks as shown in A, B, C, and D of FIG. The position data of the hook indicates whether the position of the note in the hook is at the beginning, between, or at the end. The head corresponds to A in FIG. 9, the interval corresponds to B and C in FIG. 9, and the end corresponds to D in FIG.

The additional data for the staff includes, in addition to the length data, creation order data, width data, and the like. This creation order data is data indicating the order in which the staffs were created, and common creation order data is stored for linked staffs created simultaneously. As the common creation order data, the creation order data of the first staff of the linked staff created simultaneously is used. The staff group in which the common creation order data is stored is simultaneously played in parallel. The width data is data indicating the width of the entire connected staff.

Further, if there is an additional line, data on the staff to which the musical note belongs is stored as additional data. When the cursor 25 of the note symbol is slid from the staff below the first staff line, data indicating that the cursor belongs to the upper staff is stored as additional data. When the user slides above the fifth line of the staff, data indicating that they belong to the lower staff is stored as additional data.

The performance data MP is obtained by converting the code data KD of the music symbols for display into performance data. This conversion is as shown in FIGS. The performance data MP includes step time data ST, gate time data GT, sound-on / sound-off command data KM, note number data NT, velocity data BR, and the like.

The step time data ST is data indicating the length of time from the beginning of a song or the beginning of a bar to sound on. The gate time data GT is data indicating the length of time from sound on to sound off. The command data KM is data indicating a sound on / sound off command. Note number data NT
Is data indicating the pitch. The velocity data BR is data indicating the speed or intensity of the sounding operation or the silencing operation. From the musical symbol code data KD to the performance data M
For conversion to P, intermediate data is created as required, and the intermediate data is converted to performance data MP.

[0042] 4. Overall Processing FIGS. 7 and 8 show flowcharts of the overall processing. This process is started when the power is turned on or a mode is selected by a key operation after the power is turned on. First CPU
11, the display code memory 13 in the RAM 13
1. Initialization processing such as clearing the staff memory 132, the performance memory 133, the scale table 134, the cursor point register 137, the search point register 138, and the cursor symbol register 139 is performed (step 01). Next, based on the program stored in the ROM 12, the graphic data GF such as the symbol icons 22,..., The command icons 23, and the viewports 21 are written into the graphic memory 6 and displayed on the CRT 5, as shown in FIG. (Step 02).

Next, if the mouse 1 moves based on the data from the mouse scan circuit 2, the mouse 1
Is added to or subtracted from the cursor coordinate data in the cursor point register 137 of the RAM 13 (steps 03 and 04). Then, based on the data from the mouse scan circuit 2, the mouse 1
Is turned on (step 0)
5) Whether the cursor coordinate data is on the viewport 21 of the CRT 5 (step 06), the symbol icon 22
Above (Step 07), “Play”, “Sound”
Alternatively, it is determined whether the command icon 23 is on the “file” command icon 23 (steps 08, 09, 10) or another command icon 23 (step 11).

If it is on the symbol icon 22 (step 0
7) The graphic data GF of the arrow-shaped cursor 25 written at the address of the graphic memory 6 is deleted, and the code data K of the music symbol corresponding to the symbol icon 22 is stored in the cursor symbol register 139 of the RAM 13.
D is written, and the same graphic data GF as the music symbol of the symbol icon 22 is written to the graphic memory 6 (steps 12 and 13). With this, mouse 1
Is changed from an arrow to a music symbol. Then, in steps 03 and 04, the music symbol moves as the cursor 25 on the display screen 20 of the CRT 5 in accordance with the movement of the mouse 1.

If the left click button 1a is turned on on the viewport 21 (step 06), the code data KD is stored in the cursor symbol register 139 when the cursor 25 of the mouse 1 is changed to a music symbol. (Step 14), the music symbol code data KD of the cursor symbol register 139 is written to an address corresponding to the cursor coordinate data KC of the display code memory 131 (step 15). The graphic data GF is written in the graphic memory 6 and displayed on the CRT 5 (step 1).
6).

Further, if the left click button 1a is turned on on the "performance" command icon 23 (step 08), a search / performance process described later is performed (step 17). If the left click button 1a is turned on on the "sound" command icon 23 (step 09), processing for setting the tone color of the performance part is performed (step 18). In this case, for the music score in the ensemble format, "part 1 = ..." and "part 2 = ..."
.., “MIDI 1 =...” Is displayed in a window such as “MIDI 1 =...”. Tone color data represented by numerical values is input from the keyboard 3, and tone color data is set in the tone color register 141 of the RAM 13.

Further, if the left click button 1a is turned on on the "file" command icon 23 (step 10), a recording process on the floppy disk 7 or a reproducing process from the floppy disk 7 is performed (step 19). . The recorded data includes performance data MP in the performance memory 133 of the RAM 13 and code data KD of music symbols in the display code memory 131. Also,
If the left click button 1a is turned on on another command icon 23 (step 11), a process corresponding to this is performed (step 20).

Then, the right click button 1b of the mouse 1
Is turned on (step 21), when the cursor 25 of the mouse 1 is changed to a music symbol, that is, when the code data KD is stored in the cursor symbol register 139 (step 22), the music symbol of the cursor 25 is changed. Is determined to be a chain hook (signed digit) (step 2).
3). If it is a chain hook (sign), this chain hook (hata)
Is changed so that the code data KD of this hook is changed.
Then, the additional data indicating the direction of the hook in () is changed (step 24).

As a result, as shown in FIG.
When the note hooks of the four notes of the quarter note, the sixteenth note, the eighth note, and the sixteenth note are connected to form a continuous hook, the second 16th note is obtained.
Right-click button 1 of mouse 1
It is switched by turning on b. In this case, the code data KD itself of the continuous hook may be switched by turning on the right click button 1b of the mouse 1.

In steps 21 to 23, the process of changing the shape of the music symbol of the cursor 25 cyclically every time the right-click button 1b of the mouse 1 is pressed is executed for the code data KD of the music symbol other than the hook. Is performed (step 25). In this case, if the code data KD of the music symbol in the cursor symbol register 139 is, for example, a note (rest), an upward quarter note → a downward quarter note → a quarter rest →
It sequentially circulates in the order of upward quarter note →. This cyclic change is based on the count of the value of the content data in the code data KD.

If only specific bits such as the least significant bit of each quarter note, downward quarter note, and quarter rest code data KD are different, and the other bits have the same bit configuration, only this specific bit is used. What is necessary is just +1 or -1. In order to enter this note, the user operates the numeric key of “1” on the keyboard 3 to add one dot, and operates the numerical key of “2” to add two dots. The code data KD of the symbol is changed.

Next, the middle click button 1c of the mouse 1
Is ON (step 26), and when the ON is performed on the viewport 21 (step 27), the cursor coordinate data K of the cursor point register 137 is read.
For C (x, y), the graphic data GF is written to the graphic memory 6 for all coordinate points where the value of y has been changed while the value of x remains unchanged (step 2).
8).

Thus, the auxiliary line 28 shown in FIG. 2 is drawn on the display screen 20 of the CRT 5 from the music symbol of the cursor 25. Therefore, when drawing a musical score, the upper and lower positions of each symbol can be aligned. The color of the auxiliary line 28 may be the same as or different from the color of the music symbol, and may be a laterally extending one, such as an L-shaped, T-shaped, cross-shaped, or rectangular shape. In this case, a process of writing the graphic data GF into the graphic memory 6 is also performed for all coordinate points where the value of x is changed while the value of y is not changed.

The operation for displaying the auxiliary line 28 in the step 21 may be any operation such as turning on an arbitrary key of the keyboard 3 other than turning on the middle click button 1c of the mouse 1. In addition, auxiliary line 2
The display of 8 is also performed on a pattern other than the graphic pattern 26 of the music symbol described above.

Further, in step 12, when the cursor 25 of the note symbol is slid from below the staff or below the first line of the staff or above the fifth line, the additional data of the note is added to the note symbol. It is written to the code data KD.
Thereby, the graphic pattern 26 of the additional line is added to the graphic pattern 26 of the musical note below the first line or above the fifth line of the staff.

In this case, the range to which the line is added is limited to the staff area 29. Where a plurality of staff areas 29 overlap, a staff is added to the staff on which the note symbol cursor 25 has moved. This is because data on the staff to which the note belongs is also stored in the additional data, and the direction in which the additional line is added is determined based on this data. The number of lines to be displayed is displayed every other display part 27 according to the interval from the first line or the fifth line of the staff. The number of the additional lines may be counted according to the slide interval from the staff to which the line belongs, and may be stored in the additional data.

[0057] 5. Music Symbol Writing Process FIG. 10 shows a flowchart of the music symbol writing process in step 15 described above. In this process, the music symbol of the cursor 25 determined in the above step 14 is a staff, an ensemble connection symbol for connecting the staffs, a tie (slur) / crescendo (decrescendo) / bracket symbol, and a hook (sign digit) symbol. Then, it is determined whether the head and the tail need to be designated, such as a tuplet symbol (step 101).

If YES, when the head has not been designated (step 102), the cursor coordinate data KC of the cursor 25 when the left click button 1a is turned on in step 05 is temporarily stored in the RAM 13.
The head is specified (step 104). If the head is already specified in step 102, if the code data KD of the cursor symbol register 139 is not a staff (step 103), the type of each music symbol
Display coordinate data PC, length of music symbols, etc. are temporarily stored in RAM1.
3 and the end is designated (step 10).
5). This display coordinate data PC is cursor coordinate data K
C is used as is.

In step 103, if the code data KD of the cursor symbol register 139 is a staff and both the head and the end of the staff have been designated (step 103),
Data such as the type, length, and order of each staff is temporarily stored in the RAM 13.
The lower edges of these staffs are designated (step 106). Thereby, a plurality of staffs are created simultaneously. The presence, absence, and designation of the head, tail, and lower edge are stored in the RAM 13 as flag data.

If the music symbol of the cursor 25 determined in the step 14 is a continuous hook (sign digit) symbol (step 107), when the start and end have been specified (step 108), the next Steps 109-111
Write / erase processing of the music symbol code data KD. The change of the direction of the hook (sign) symbol is performed in step 24, and when the desired direction is reached, the direction is determined by turning on the left click button 1a.

Next, when the code data KD of the music symbol is written in the address of the display code memory 131 corresponding to the display coordinate data PC, and when the code data KD of the same music symbol is already written in this address, (Step 109), the code data KD is deleted (Step 110).

If the code data KD of the same music symbol has not been written (step 109), the RAM 1
3 is written or the code data KD stored in the cursor symbol register 139 is written (step 111). In this case, when the code data KD of the already written music symbol is different from the code data KD of the music symbol to be newly written, the code data is written to the spare area of the display code memory 31 or is written as the above-mentioned spare data.

When the vertical line code data KD indicating a bar break is written into the display code memory 131 on the staff in the ensemble format, the vertical line code data KD is automatically placed at the same position on the other staffs. Written. The address of the write coordinates is represented by coordinates (x, y + d + e + f) (x, y + 2d + 2e) with respect to the coordinates (x, y) of the write address of the vertical line.
+ 2f) (x, y + 3d + 3e + 3f)... In this case, when the staff areas 29 overlap, the y coordinate data of the display entry point 24 of each staff is used. In this writing, when a predetermined operation is performed, such as when an arbitrary key of the keyboard 3 is turned on, writing to another staff is not performed.

As described above, each music symbol can be input and displayed at an arbitrary entry point. Musical symbols such as staves, ensemble concatenation symbols that connect staves, ties (slurs) / crescendos (decrescendos) / brackets, chain hooks (digits), and tuplets Can be specified arbitrarily. Further, the clef can be input and displayed separately from the staff, and an arbitrary score can be created.

[0065] 6. Search / Performance Processing FIG. 11 shows a flowchart of the staff search processing in the flowchart of the search / performance processing in step 17 described above. In this process, the CPU 11
The search coordinate data SC of the 13 search point registers 138 is cleared, and the search coordinate data SC (x,
y) = (0, 0), the staff number data SN of the staff number register 140 is also cleared (step 31), and (x, y) = in the display code memory 131.
Data at an address corresponding to the coordinates of (0, 0) is read (step 32).

If the read data is not the staff code data KD (step 33), the search coordinate data SC of x is incremented by 1 (step 34), and the search coordinate data SC of x is displayed on the display screen 20. Until the right end is reached (step 35), the search process of the staff code data KD in steps 32 and 33 is performed. When the search for one row of y = 0 is completed (step 35), the search coordinate data SC of x is set to “0” and the search coordinate data SC of y is set.
Is incremented by 1 (step 36), and the same search processing is performed (steps 32 and 33), and the search coordinate data SC (x,
This operation is performed until y) reaches the end of the display screen 20 (step 37).

By this search, the staff code data K
If D is read out (step 33), the presence / absence bit of the connected staff of the additional code in the staff code data KD is determined, and it is determined whether or not the staffs created and played simultaneously are connected. (Step 38). If another staff is not connected, the data of the staff type and length stored in the searched address of the display code memory 131 is read out, and the size data and the position data are created. The data is written into the address corresponding to the staff number data SN in the memory 132 (step 39), and the staff number data SN
Is incremented by 1 (step 40).

The type of staff is distinguished from a five-wire type, a one-wire type and the like. The position of the staff is the search coordinate data S
C (x, y), that is, the display coordinate data PC of the display entry point 24 of the staff. The staff size is the size a + b + c and d + e + f of the staff area 29. The staff number data SN is data stored in the staff number register 140, and indicates a write address of each data of each staff and a performance order of each staff. The a, c, d, e, and f are determined in advance in accordance with the type of staff, and b represents data indicating the length of the staff as it is. As the values of a, c, d, e, and f, arbitrary values equal to or greater than “0” are selected. In this case, d,
Depending on how the value of f is set, the staff areas 29 may overlap each other.

In step 38, if the searched staffs are connected, a bit indicating whether or not the head of the connected staff in the additional code of the code data KD of this staff is determined (step 41). . If it is the first staff of the connected staff, the data of the type and length of the staff stored in the searched address of the display code memory 131 are read out as in step 39, and the size data and the position data are read. Is written in the address of the staff memory 132 corresponding to the staff number data SN (step 42), and further, the connection order data of "1" is written (step 43), and the staff number data SN is incremented by one. (Step 44).

Then, the search coordinate data SC (x, y)
To the y coordinate data of d + e +
The data of the address in the display code memory 131 corresponding to the coordinates to which f has been added is read, and if there is a connected staff (step 45), the staff stored in the searched address is stored as in steps 42 to 44 described above. Is read out, written to the next address of the staff memory 132, and the connection order data of "2" is written (step 4).
2-44).

Thereafter, the display code memory 1 corresponding to the coordinates of each d + e + f of the read staff size data is read.
The data of the address 31 is read out (step 45), and the data of the type, position and size of the staff are similarly stored in the staff memory 13.
2, and the concatenation order data of "3", "4", "5",...

This processing is performed up to the width data of the connected staff (step 45).
C (x, y) is returned to the display coordinate data PC of the display entry point 24 of the leading staff of the connected staff (step 46). Even if the connected staff is searched again in the subsequent search, data is not overwritten in the staff memory 132 (step 41).

In the search for connected staffs, after searching all staffs regardless of the presence or absence of connection, a search for a connected portion is performed, a connection flag is set for each connected staff, and this flag is present. For this, the step time data ST may be adjusted in step 77 described later.

These search processes are performed in accordance with all the staff code data KD stored in the display code memory 131.
It is done about. When the search is completed for all addresses of the display code memory 131 (step 37), the code data KD of the music symbol transferred to the staff memory 132
Is performed (step 4).
7).

The search direction is the x-axis direction, which is repeated. When a plurality of staffs are displayed,
Those located above are searched first, and when they are on the same line, the one located on the left is searched first, and automatic performance is performed in this search order. Note that the start point and end point of this search are (0,
(0) to (END, END) as well as (0, EN
D) to (END, 0), (END, END) to (0, 0), etc., and the search direction may be the y-axis direction, as in the music symbol search processing described below, or x
The axis and the y-axis may be searched in opposite directions.

It should be noted that the viewport 21 searched in the search / performance processing is a command icon 23 for specifying a range.
May be performed only for the musical score in the range specified using. In this case, the search coordinate data SC (x, y) set in step 31 is not (0, 0) but the upper left coordinate data of the specified range.
Are the x-coordinate data at the right end of the specified range and the coordinate data at the lower right of the specified range.
Is the x-coordinate data at the left end of the specified range.

[0077] 7. Music Symbol Search Process FIG. 12 is a flowchart of the music symbol search process in step 47. In this process, the position data of the first staff of the staff number data SN = 0 of the staff memory 133 written in the steps 39 and 42 by the CPU 11, that is, the display entry point 24
Is read out and is used as data search coordinate data SC (x, y) (step 51).
The code data KD of the music symbol at the address corresponding to the (x, y) coordinates in the display code memory 131 is read (step 52).

If the read data is not the music symbol code data KD (step 53), the search coordinate data SC of y is incremented by 1 (step 54), and the search coordinate data SC of y is equal to the above d + e + f, ie, five. Until the lower end of the line area 29 is reached (step 55), the music symbol search processing of steps 52 and 53 is performed. And
When the search for one column of x = 0 is completed (step 5)
5) The search coordinate data SC for y is set to “0”, the search coordinate data SC for x is incremented by 1 (step 56), and the same search processing is performed (steps 52 and 53).
y) = (a + b + c, d + e + f), that is, until the end of the staff area 29 is reached (step 57).

If the code data KD of the music symbol is read out by this search (step 53), a conversion process to the performance data MP is performed (step 58). If the search reaches the end of the staff area 29 in step 57, it is determined whether or not there is code data KD for another staff (step 59). If so, the search in steps 51 to 58 is performed. Repeat the process. If not, an automatic performance process corresponding to the performance data MP written in the performance memory 133 is performed (step 60).

In this automatic performance processing, the performance data MP described below is read from the performance memory 133, and the sound is turned on at the speed according to the tempo data of the tempo buffer in the RAM 13 every time the step time data ST elapses.
The sound is turned off every time the gate time data GT elapses. In this case, the timbre of the musical tone is based on the timbre data stored for each performance part in the timbre register in the RAM 13, the pitch is based on the note number data NT of the performance data MP, and the velocity such as the volume is the same as the performance data MP.
Based on velocity data BR. In this case, the timbre data is specified by the above-mentioned "sound" command icon 23, stored in the timbre register of the RAM 13, and stored in the performance memory 133 as one of the performance data MP in steps 79 and 80 described below. You may write it.

8. Performance Data Creation Processing FIGS. 13 and 14 show a flowchart of the performance data creation processing in step 58 described above. In this process, C
The PU 11 performs a process of creating the performance data MP from the code data KD of the music symbol searched in the step 53. First, if the searched music symbol is a clef (step 61), the display coordinate data P of each display part 27 in the y-axis direction of the staff area 29 is displayed.
Create note number data NT corresponding to C
Writing to the scale table 134 of M13 (Step 6)
2). For example, if the clef is a treble clef, the display coordinate data PC corresponds to the note number data NT of the pitch E4 for the display coordinate data PC of the first line of the staff.
The display coordinate data PC of the first interval corresponds to the note number data NT of the pitch F4, and the display coordinate data PC of the second line corresponds to the note number data NT of the pitch G4.

If the searched music symbol is a key signature or an accidental symbol (step 63), the note number data NT of the scale table 134 corresponding to the display coordinate data PC of this symbol is raised or lowered by a semitone. It is changed (step 64). If the searched music symbol is a vertical line indicating a bar break (step 65), the scale table 134 changed in step 64 is restored (step 66). In this case, the key signature is not restored. For the score in the ensemble format, the step time data ST up to the vertical line and the gate time data GT
In order to align the total time data with the longest one, the value of the next step time data ST of each musical score is increased (step 67).

If the searched music symbol is a tempo symbol (step 68), the tempo data TP of this tempo symbol is set in a tempo buffer 142 in the RAM 13 (step 69). Thereby, the above step 5
The automatic performance speed of 0 is determined. The tempo data TP may be written in the head area of the performance data MP in the performance memory 133.

If the searched music symbol is a dynamic symbol (step 70), velocity data BR corresponding to the value of the dynamic symbol is created (step 71). The dynamic symbols correspond to a plurality of stages from pianissimo (pp) to fortessimo (ff). In this case, if the code data KD of the crescendo / decrescendo music symbol is searched (step 72), the values from the value of the first dynamic symbol to the value of the last dynamic symbol of the crescendo / decrescendo are proportionally converted in each note. To create velocity data BR (step 73).
If there is no dynamic symbol, preset data is used as velocity data BR (step 74). For the above-mentioned proportional conversion, an operation other than the proportional conversion may be performed based on an arithmetic expression stored in the RAM 13 or the like.

If the searched music symbol is a note symbol (step 75), the display coordinate data PC of this note symbol is converted by the scale table 134 created or changed in steps 62, 64, and 66 to generate a note. The number data NT is set (step 76). Next, the step time data ST is set to a predetermined constant value (step 7).
7) The gate time data GT is obtained by performing an arithmetic operation according to an articulation symbol such as staccato or tenuto on a note length corresponding to the type of note (step 78).

The step time data ST, the note number data NT, and the velocity data BR are stored in the performance memory 1 together with the sound-on command.
33 (step 79), and the gate time data GT and the note number data NT together with the sound-off command are written into the performance memory 133 (step 80). Although the velocity data BR of the sound-off command is set to “0”, an arbitrary value may be set.

If there is connection order data written for the connection staff in steps 43 and 44, the step time data ST determined in step 77 is used.
Are unified. For those without concatenation order data,
The step time data ST is determined so that sound generation starts after the last note of the previous staff is sounded. For each staff in the viewport 21, the performance data MP
The song numbers are stored in a box, and each song is stored in the order of the song numbers in step 60.
You may play with In this case, the same music number is set for the connected staff.

If the code data KD of the searched music symbol is a rest symbol (step 81), the step time data ST of the next performance data MP includes time data of a rest length corresponding to the type of the rest. (Step 8
2).

If the code data KD of the searched music symbol is a tie (step 83), the note length of each note up to the end of the tie is compared with the gate time data GT of the first sound-on command of the tie. Are accumulated (step 84).

If the code data KD of the searched music symbol is a tuplet (step 85), sound-on and sound-off commands corresponding to the number of tuplets are given to the performance memory 1.
33, and the gate time data GT obtained by equally dividing the gate length data GT of the note length divided by the tuplet by the number of tuplets is stored in the performance memory 133 in correspondence with the above sound on and sound off commands. writing,
The step time data ST and the velocity data BR are set to predetermined constant values (step 86).

If the code data KD of the searched music symbol is the code data KD of another music symbol (step 87), data corresponding to the music symbol is written to the performance memory 133 (step 88). When these conversion processes are performed on the code data KD of all music symbols in the staff memory 132 (step 8).
9) Return. Thus, the code data KD of the music symbol can be converted into the performance data MP, and in the above step 60, the automatic performance is performed based on the performance data MP.

The present invention is not limited to the above embodiments, but can be variously modified without departing from the spirit of the present invention. For example, if the code data KD of the staff symbol is found in the step 33, the music symbol search processing in the steps 51 to 57 may be directly performed, and then the process may return to the step 34. Further, the size data of the connected staff may be processed as the entire size of all the connected staff areas 29. In searching for a music symbol, instead of searching for the code data KD of the music symbol, the graphic data GF of the music symbol is searched. When the graphic data GF of the music symbol is found, the graphic data GF is compared with each graphic data in the RAM 13. Code KD of music symbol
May be determined. Further, steps 05, 21, 2
