  FIG. 5 is a diagram showing a configuration example of a performance information file according to the present embodiment. In the present embodiment, the performance information file 22 has performance information for a plurality of tracks, and each track has a list structure. As shown in FIG. 5, the performance information file 22 stores records (see reference numerals 501 and 502) indicating MIDI events for each track. Each record includes mMsg (MIDI data), ITime (sounding start time), IGate (sound length), * next (pointer to the next note), and * prev (pointer to the previous note). The pitch of the musical tone to be generated is determined by the MIDI data (mMsg). The sound generation start time of the musical sound and the length of time to be sounded are determined by the sound generation start time (ITTime) and the sound length (IGate). In the present embodiment, there may be a plurality of records having the same sound generation start time (ITTime) in the same track. This indicates that each note of the plurality of records is a chord constituent sound. In the present embodiment, for notes that are chord constituent sounds, records are arranged in order of increasing pitches shown in MIDI data (mMsg). That is, by following the pointer “* next”, it is possible to specify notes that are chord constituent sounds in descending order of pitch.

  In the example of FIG. 5, the record of the second note on track 0 (see reference numeral 511) is designated by the item * next of the record of the first note on track 0 (see reference numeral 501). The reverse specification can also be realized by referring to the item * prev of the record 511. Further, the second record (see reference numeral 512) of track 1 is designated by the item * next of the record of the first note of track 1 (see reference numeral 502).

  6 and 7 are diagrams showing a configuration example of the score information file according to the present embodiment. As shown in FIG. 6, in the present embodiment, the score information includes a record group (see symbols 601 and 602) indicating information related to the note graphic of the note drawn on the score for each stage. As shown in FIG. 7, the score information includes a record group (see reference numerals 701 and 702) indicating information on the measure drawn on the score for each measure. Here, that the note graphic is drawn on the “same stage” means that the note graphic is drawn on the same staff. That is, “stage” means a set of staffs. For example, in a four-part choir score, a part (soprano) is drawn in the “same stage” in principle. In addition, a plurality of parts (for example, soprano and alto) may be drawn on the “same stage”.

  As shown in FIG. 6, in the score information file 24, a record relating to a note (for example, reference numeral 601) includes mEvent (pointer to a MIDI event), ITime (pronunciation start time), sMeas (measure number), sBeat (beat). Number), (ix, iy) (coordinates), cLine (line number), cNoteType (note type), cBou (vector of note stem (stick)), cChord (chord), cHata (suffix (hat)) , CRenkouS (continuous digit start point), cRenkouE (continuous digit end point), cTie (tie), * next (pointer to the next note), * prev (pointer to the previous note), and the like.

  Any one of the records of the performance information file 22 shown in FIG. 5 is specified by the pointer (mEvent) to the MIDI event. Further, the sound generation start time (ITTime) matches that of the record in the performance information file 22 specified by the pointer (mEvent) to the MIDI event. The measure number (sMeas) indicates the number of the measure to which the note belongs, and the beat number sBeat indicates the number of the beat in which the note is located in the measure.

  The coordinates (ix, iy) indicate the coordinates of the note graphic of the drawn note, and the line number (cLine) is for identifying the line assigned to the track to which the note belongs at the stage where the note graphic is drawn. Is.

  The note type (cNoteType) includes all notes, half notes, quarter notes, and the like. In addition, the types of notes include rest types (for example, full rest, half rest, quarter rest, etc.). The bar vector (cBou) indicates the direction of the stem (+ for upward,-for downward) and its length. The direction of the stem is determined by the line number. The chord information (cChord) indicates a chord component other than a single tone, a chord start tone (the lowest tone in the chord), a chord end tone (the highest tone in the chord), a chord start tone or a chord end tone. “CHata” indicates the number of stems (for example, 0 to 5). The beam start point (cRenkouS) and beam end point (cRenkouE) indicate the start point and end point of the tuplet, and how many tuplets the tuplet is (the number of links). Further, the pointer to the next record (* next) and the pointer to the previous record (* prev) have the same functions as those of the performance information file 22. Accordingly, the record 502 of the next note can be specified by the pointer “* next” of the record 501 of the first note at stage 0. The reverse can also be specified by “* prev”.

  As shown in FIG. 7, in the musical score information, a record relating to a measure (for example, reference numeral 701) includes iMeasN (measure number), iDanN (stage number), (ix, iy) (coordinates of the reference position of the measure), iMeasLen ( Reference range), cCref (clef), cKeySigSF (key), cMeasBar (bar), * next (pointer to the next note), * prev (pointer to the previous note), and the like.

  The bar number (iMeasN) and the stage number (iDanN) can specify the number of bars in which stage. In addition, the position of the measure in the musical score drawn is specified by the coordinates (ix, iy) of the reference position of the measure. The clef (cCref) is for identifying clefs such as treble, treble, and treble. Further, the key (cKeySigSF) indicates how many sharps or flats are arranged at which position. In addition, the bar line (cMeasnBar) indicates that the bar line of this bar is a bar line that passes through, a bar line having a repetition symbol, a stop line, or the like.

  Next, the score information generation process (step 305 in FIG. 3) according to the present embodiment will be described in more detail. 8 and 9 are flowcharts showing the score information generation processing according to the present embodiment. As shown in FIG. 8, the musical score information generation unit 14 first performs a quantization process and a sound length process (steps 801 and 802).

  In the quantizing process and the sound length process, the score information generating unit 14 refers to the records (for example, reference numerals 501 and 511 in FIG. 5) of the performance information file 22 for the notes in order from the first note in each track. The sound generation start time (ITTime) and the sound length (IGate) of the record are specified. If the sounding start time (ITTime) of the note does not match a predetermined resolution unit, the score information generating unit 14 corrects the sounding start time so as to match the resolution unit. Also, if the sound length (IGate) is shorter than the unit of decomposition or does not match the resolution unit, the sound length (IGate) is corrected to match the resolution unit. The sound generation start time (ITTime) and the sound length (IGate) in the record are updated by the quantize process and the sound length process, and thereby the performance information file 22 is updated.

  Next, the score information generating unit 14 assigns a line number to each track to be drawn on the same stage, and associates a stage number and a line number with each track (step 803). For example, in a chorus score, if track 0 corresponds to a soprano part and track 1 corresponds to an alto part, if the soprano part and the alto part should be drawn on the same stage (stage number: 0) Track 0 is given stage 0 and line 0. Actually, information indicating the stage 0 and the line 0 is associated with the record of the track 0 in the performance information file 22. Also, stage 0 and line 1 are given to track 1. Actually, information indicating the stage 0 and the line 1 is associated with the record of the track 1 in the performance information file 22. Also, if the track 2 corresponds to the tenor part and the track 3 corresponds to the bus part, if the tenor part and the bus part are to be drawn on the other same stage (stage number: 1), the track 2 Are provided with stage 1 and line 0. Actually, information indicating stage 1 and line 0 is associated with the record of track 2 in the performance information file 22. Further, stage 1 and line 1 are given to the track 3. Actually, information indicating the stage 1 and the line 1 is associated with the record of the track 3 in the performance information file 22. For example, the association is realized by storing the track number and the information indicating the stage and the line in the storage device 20 as a set.

  Next, a track variable indicating the number of the track to be processed is initialized, and individual information generation (step 806), chord processing is performed for each track until the processing is completed for all tracks (see steps 805 and 809). (Step 807) and consecutive digit processing (Step 808) are executed.

  In the individual information generation, chord processing, and consecutive digit processing, information necessary for records relating to notes is generated in the score information. In individual information generation, for each note, based on the note length (IGate), the note type, for example, the color of the note head (tama) (black color (black fill) or white color (black color) Only the outline)), the direction and length of the stem (bar), the number of stems, etc. are determined, and the information is temporarily stored in the storage device 20 in association with the note. If there is a silence between adjacent notes in the track, the section becomes a rest. Accordingly, the type of rest according to the length of the silent state is determined, and the rest information is temporarily stored in the storage device 20.

  In the chord processing, a note having the same pronunciation start time (ITTime) is found for each track, and information indicating that these are chords is temporarily stored in association with the note. It is stored in the device 20. Also, in the consecutive digit processing, when a plurality of consecutive notes should be represented as a tuplet based on the sound generation start time (ITTime) and the sound length (IGate) for each track, Information related to the mark is associated and stored in the storage device 20.

  For example, the line number assigned to the track in step 803 corresponds to the line number (cLine) in the record indicating the note in the score information file 24. Further, the direction (upward or downward) of the stem vector is determined according to the line number assigned to the track. For example, if two note notes should be drawn at a certain level, the note stem of the note on the high-side line is up, and the note stem of the note on the low-side line is down The record information related to the notes in the score information file 24 is generated and stored in the storage device 20.

  Information generated in the individual information generation includes a note type (cNoteType), a stem vector (cBou), and a stem (cHata) in the record indicating the notes in the score information file 24. It corresponds to. The information generated in the chord process corresponds to a chord (cChord) in the record indicating the note in the score information file 24. The information generated in the beam processing corresponds to the beam start point (cRenkouS), the beam end point (cRenkouE), and the like in the record indicating the notes in the musical score information file 24.

  Next, the score information generating unit 14 initializes variables indicating the steps (step 901), and repeatedly executes the processing of steps 903 to 905 until the processing is completed for all the steps (see steps 902 and 906). .

  First, the score information generating unit 14 checks the information of the stage and line associated with the record related to the note in the score information file 24, and determines whether there is a track to be merged (step 903). In step 903, when there are a plurality of lines at the same stage, the notes of the track corresponding to each line of the same stage are to be merged. If it is determined Yes in step 903, the score information generating unit 14 rearranges the corresponding notes of the plurality of tracks in time order (step 904).

  In the case where the above-described track 0 corresponds to the soprano part and track 1 corresponds to the alto part, the case where the soprano part and the alto part should be drawn in the same stage (stage number: 0) 0 is associated with line 0 of stage 0, and track 1 is associated with line 1 of stage 0. Therefore, the records of the track 0 and the record of the track 1 in the score information file 24 are rearranged in the order of pronunciation start time (ITTime). In actual processing, information indicating the order of records in the rearranged performance information file 22 may be stored in the storage device 20.

  As shown in FIG. 10, for each record (reference numerals 1001 to 1003) of the performance information file 22 relating to the track 0 of a certain stage, the note N to the note N + 2 of the line 0, the sound generation start time ITime is t, t + 2, Consider t + 3. For each record (reference numerals 1011 to 1013) of the performance information file relating to note M to note M + 2 on track 1 and line 1 of the same stage, it is considered that the sound generation start time ITime was t, t, and t + 3, respectively. In this case, as a result of the rearrangement, the records are in the order of records 1001, 1011, 1012, 1002, 1003, and 1013 (see the bottom row in FIG. 10). When there are a plurality of lines of notes at a certain stage as described above, the notes (records) of these notes are rearranged in the order of the sound generation start time for the tracks to be drawn on the same stage. By rearranging in the order of the sound generation start times, it is possible to refer to the pitches and pitches of the notes in the order of the sound generation start times even in different tracks.

  When it is determined No in step 903 or when step 904 ends, the score information generating unit 14 executes a drawing position information generating process (step 905). FIG. 11 is a flowchart illustrating an example of the drawing position information generation process according to the present embodiment.

  As shown in FIG. 11, in the drawing position information generating process, the score information generating unit 14 refers to the records arranged in the order of the pronunciation start time, and temporarily determines the drawing position of each note of the record ( Step 1101). In step 1101, the coordinates (ix, iy) are provisionally determined according to the pitch (mMsg) and the sounding start time (ITTime) of the note record.

  As described above, in step 803 and steps 806 to 808, the line number (cLine), the type of note including a rest (cNoteType), the vector of stems (sticks) (cBou), and the tail (Hata) ) (CHata), chord (cChord), beam start point (cRenkouS), beam end point (cRenkouE), and the like are generated and temporarily stored in the storage device 20. Therefore, these values and the values of the coordinates (ix, iy) are stored in a record (see FIG. 6) relating to the notes in the score information file 24.

  Next, the note pointer vn for specifying the note to be processed is initialized, and the following steps 1104 to 1109 are repeatedly executed until the processing for the note indicated by “no” and the pointer vn is completed (see steps 1103 and 1110). ). Hereinafter, a note indicated by the note pointer vn is referred to as a note vn, and a note indicated by the note pointer vnx is referred to as a note vnx.

  First, in order to find a note having the same sounding start time as the note vn to be processed, the note pointer vnx is initialized, and the notes arranged in the order of the sounding start times described above are on a line different from the note vn and the note vn. Note that the note that follows is a note vnx. In the record arranged in the order of sound generation start time, the drawing position information correction unit 16 performs note vnx on another line between the note vn and the next note (next note vn) that is the same line as the note vn. The processing from step 1106 to step 1111 is executed (see step 1105).

  The drawing position information correction unit 16 determines whether or not the sounding start time of the note vn and the sounding start time of the note vnx are the same (step 1106). The note vnx is used to determine what relationship a note of a line different from the line of the note vn has with the note vn.

  If the note vn and note vnx have the same sounding start time (Yes in step 1106), the drawing position information correction unit 16 determines whether the note vn and the note vnx are notes (step). 1107). When it is determined Yes in step 1107, the drawing position information correction unit 16 executes a note drawing position adjustment process (step 1108). FIG. 12 is a flowchart showing an example of the note drawing position adjustment process according to the present embodiment. As shown in FIG. 12, the drawing position information correction unit 16 determines whether or not the note vn and the note vnx are within 2 degrees (step 1201), and is not within 2 degrees (No in step 1201). The coordinates in the record relating to the notes vn and vnx of the score information file 24 are not changed (step 1207).

  On the other hand, if it is determined Yes in step 1201, the drawing position information correction unit 16 determines whether the note vn and the note vnx have the same pitch (whether these notes are perfect once). (Step 1202). When it is determined No in step 1202, that is, when the note vn and the note vnx are not in the same pitch, the drawing position information correction unit 16 corrects the position of one note head (step) (step 1203). ). In step 1203, the coordinates of the notes belonging to the bass side line are corrected so that the note head position of the note graphic is shifted to the right. The corrected coordinates (ix, iy) are stored in the record related to the note in the score information file 24.

  When it is determined No in step 1202 (when it is completely 1), the drawing position information correction unit 16 determines whether or not the sound lengths of the note vn and the note vnx match (step 1202). When it is determined Yes in step 1202, the drawing position information correction unit 16 does not change the coordinates in the record relating to the notes vn and vnx of the score information file 24 (step 1207). In this case, in the musical score drawing process described later, both the musical note graphic component (note head, note stem, etc.) related to the note vn and the musical note graphic component related to the note vnx are drawn on the image. However, since the shape and position of the note heads are exactly the same, the shape of the note stem extends vertically from a completely overlapping note head.

  If it is determined No in step 1204, the drawing position information correction unit 16 determines whether the note vn and the note vnx have the same note head (tama) (step 1205). For example, if both are black eggs (black fill) or both are white eggs (black outline only), it is determined Yes in step 1205. In step 1205, it is determined that the note heads (tama) are not the same for all notes and half notes (including half note).

  If it is determined No in step 1205, the drawing position information correction unit 16 corrects the position of one note head (step 1203). If it is determined Yes in step 1205, the drawing position information correction unit 16 further determines whether the note points of the note vn and the note vnx match (step 1206). For example, if there is a mark point on both sides, or if there is no mark point on both sides, “Yes” is determined in step 1206.

  If it is determined No in step 1206, the drawing position information correction unit 16 corrects the position of one note head (step 1203). On the other hand, when it is determined Yes in step 1206, the drawing position information correction unit 16 does not change the coordinates in the record relating to the notes vn and vnx of the score information file 24 (step 1207). Therefore, in the musical score drawing process, both the musical note graphic component (note head, note stem, etc.) related to the note vn and the musical note graphic component related to the note vnx are drawn on the image. However, since the shape of the note head (including the presence or absence of a note dot) and the position coincide with each other, the shape of the note stem extends vertically from the completely overlapping note head. The following example can be considered for the note vn and the note vnx that are judged as Yes in step 1206 and proceed to step 1207. For example, if the note on line 0 is a quarter note and the note on line 1 is an eighth note of the same pitch, it is drawn with the note heads overlapped.

By the above steps 1201 to 1207, drawing of notes according to the following cases is realized.
(1) When the sound generation start time is the same and the pitch (pitch) and the tone length match, the drawing position remains unchanged. As a result, a note with one note head and a note stem extending vertically is drawn.
(2) Even when the sound generation start time is the same and the pitch (pitch), note head, and note point coincide, the drawing position remains unchanged.
(3) Even when the sound generation start times are the same and the pitches (pitches) are the same, if the note heads do not match or the note dots do not match, the drawing position of the note heads on the bass side line is Shifted to the right.
(4) When the sound generation start time is the same and the pitch is 2 degrees (long and short 2 degrees) or 1 degree, the drawing position of the note head of the bass line is shifted to the right.

  When the note drawing position adjustment process (step 1108 in FIG. 11) is completed, the note pointer is moved, and the processes after steps 1105 and 1106 are executed for the next note vnx.

  When it is determined No in step 1107, the drawing position information correction unit 16 determines whether the note vn and the note vnx are rests (step 1109). If it is determined No in step 1109, the process proceeds to step 1111. If it is determined Yes in step 1109, the drawing position information correction unit 16 executes rest drawing position adjustment processing (step 1110). FIG. 13 is a flowchart showing an example of rest drawing position adjustment processing according to the present embodiment. As illustrated in FIG. 13, the drawing position information correction unit 16 determines whether or not the sound lengths of the note vn and the note vnx match, that is, whether or not they are the same type of rest (step 1301). If YES in step 1301, the coordinates (ix of the record of the score information file 24 for each note are drawn so that each note graphic (in this case a rest graphic) is drawn at the same position. , Iy) is corrected (step 1302).

  In the present embodiment, in the drawing position provisional determination process (step 1101 in FIG. 11), with regard to rests, the position in the vertical direction is determined in advance according to the line number. For example, if there are two lines 0 and 1, the rest figure of line 0 on the treble side is positioned higher so that the two do not overlap, and the rest figure of line 1 on the bass side is more By positioning it at the bottom, even if it is the same sounding start time, it is set so that both do not overlap. Therefore, in step 1302, when the two rest figures are made to coincide with each other in the vertical direction, the two rest figures are completely overlapped.

  On the other hand, when it is determined No in step 1302, the drawing position information correction unit 16 does not change the coordinates in the record of the musical score information regarding the notes vn and vnx (step 1303). That is, the two rest figures are drawn in a state shifted in the vertical direction.

  When the rest drawing position adjustment process (step 1110) is completed, the note pointer is moved (step 1111), and the processes following steps 1105 and 1106 are executed for the next note vnx.

  As shown in FIG. 9, when the drawing position information generation process (FIG. 11) ends, the score information generation unit 14 and the drawing position information correction unit 16 perform the processes of steps 903 to 905 for the next stage (step 906). Execute.

  As described above, in the present embodiment, the musical score information generation unit 14 is a stage in which a note graphic corresponding to a note is to be drawn, and for each stage to which any track is assigned, the musical note graphic is added to the corresponding stage. Pointer to the record of the performance information file related to the note to be drawn, position information to draw the note graphic corresponding to the note, note type of note including rest, direction and length of the stem, and note stem A musical score information file 24 including information and a record of musical score information of the note is generated and stored in the storage device. In addition, in order to draw note figures of notes of a plurality of tracks on the same stage, a line number is associated with each track to be drawn on the same stage, and the score information generating unit 14 performs a note according to the line number. The direction of the trunk is determined. Furthermore, in the present embodiment, when the drawing position information correction unit 16 matches the pronunciation start time for notes on different lines, the pitch is within two degrees and is not the same pitch, or the same pitch. If the note heads or the dot points do not match, the position information for drawing the note graphic corresponding to the note is corrected so that the note graphic of one note is moved in the horizontal direction.

  Therefore, according to the present embodiment, for a note having the same pronunciation start time, if the note has a relationship of 2 degrees (long / short 2 degrees or increment 1 degree), the drawing position of the note graphic of one note Is shifted. Even if the pitches are the same, if the note heads or the dot points do not match, the drawing position of the note graphic of one note is similarly shifted. As a result, only when it is appropriate that the note figures of the two lines of notes are drawn at the same position, a note figure with a stem extending vertically from a single note head in the score is displayed. Can be expressed appropriately.

  In the present embodiment, the musical score information generation unit 14 determines the position in the vertical direction where the note graphic corresponding to the rest is to be drawn according to the line number when the note type is rest. . Further, the drawing position information correction unit 16 determines that, for notes of different lines, when the note type of the note is rest and the sound lengths of the rest match when the pronunciation start times match. Then, in order to match the drawing position of the rest corresponding to each note, the information regarding the drawing position of the musical note figure corresponding to the rest is corrected so that the musical note figure corresponding to the rest is moved in the vertical direction.

  Therefore, according to the present embodiment, rest figures having the same sound length that should be at the same position in different lines are overlaid and drawn. On the other hand, rest figures having different sound lengths are shifted in the vertical direction so that it is clear which line rests are clear.

  Next, the score information drawing process (step 306) in FIG. 3 will be described. FIG. 14 is a flowchart showing an example of a score drawing process according to the present embodiment. As shown in FIG. 14, in the score drawing process, the score drawing processing unit 18 draws a background drawing, that is, a staff as a background of the score (step 1401), and then initializes a bar counter (step 1402). ). Thereafter, notes are drawn in units of measures until drawing for all the measures is completed (see step 1403 and step 1410).

  The score drawing processing unit 18 refers to the record (see FIG. 7) related to the measure in the score information file 24, and executes the drawing of the musical note figure based on the information shown in the record related to the measure (step 1404). In step 1404, bar lines, clefs, and the like are drawn according to the coordinates (ix, iy) of the reference position of the bar.

  Next, a note graphic is drawn in the bar. The score drawing processing unit 18 initializes the note pointer (step 1405), and draws a note graphic corresponding to the note at a predetermined position for all notes in the measure (see steps 1406 and 1409). The score drawing processing unit 18 refers to the record (FIG. 6) regarding the note in the score information file 24 for the note indicated by the note pointer, and determines the position where the note graphic should be drawn based on the coordinates (ix, iy). Then (step 1407), a note graphic is drawn at the position to be drawn according to the record information about the note (step 1408). When the process is completed for a certain note, the processes of step 1407 and step 1408 are executed for the next note. When the drawing of the note graphic is completed for all notes of a certain bar, the processing from step 1406 to step 1409 is repeated for the next bar (see step 1410).

  FIG. 15 and FIG. 16 are diagrams showing an example of a score created by the score creation / display apparatus according to the present embodiment. In FIGS. 15A to 15E, musical note graphics of two lines, a high-pitched line and a low-pitched line, are drawn on the same stage. In the example of FIG. 15A, it can be understood that the musical note graphic group 1501 for the high-pitched line and the musical note graphic group 1502 for the low-pitched line are appropriately drawn. In the example of FIG. 15B, the rests and notes on the high-pitched line coincide with the rests and notes on the bass-side line. Accordingly, the rest figures 1511 and 1512 are drawn by superimposing the high-pitched line and the low-pitched line. The note 1513 is also drawn with the note heads overlapped because the note start time is the same and the pitch (pitch) and tone length are the same for the notes on both lines. Therefore, a note figure is drawn with one note head and a note stem extending vertically. The same applies to the note graphic group 1521 for the high-pitched line and the note graphic group 1522 for the low-pitched line in FIG.

  In FIG. 15D, the note 1531 and the note 1532 are in a relationship of 2 degrees, and the note graphic 1532 of the bass line is drawn in a state shifted to the right side. In FIG. 15 (e), the note 1541 and the note 1542 have the same pitch (pitch), but the note heads (tama) do not match, so the note figure 1542 of the bass side line is shifted to the right. It is drawn in the state.

  In FIG. 16, the pitch (pitch) is the same for the notes on the high-pitched line (see reference numerals 1601 and 1602) and the note at the beginning of the beat (see the signs 1611 and 1612) on the low-pitched line. . In addition, note lengths are not the same, but note heads and note points are the same. Therefore, the note heads are drawn in a superimposed manner.

  The present invention is not limited to the above embodiments, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say.

  In the above embodiment, tracks correspond to lines, and notes belonging to a plurality of lines are drawn on the same stage. The present invention is not limited to the above-described embodiment, and it is also possible to divide a single track into a plurality of lines and draw the notes of the single track (a plurality of lines) on the same stage. Applicable.

  FIG. 17 is a flowchart showing a score information generation process according to another embodiment of the present invention. 18, steps 1701, 1702, and 1703 are the same as steps 801, 802, and 804 in FIG. 8, respectively. Steps 1704, 1706, 1707, 1708, and 1710 in FIG. 18 correspond to steps 805, 806, 807, 808, and 809 in FIG. 8, respectively.

  As shown in FIG. 17, in another embodiment, instead of step 803 in FIG. 3, processing (line separation) is performed for each track to which line the notes of the track belong (step separation). 1705). In the line separation, for each track in the score information file 22, the record of the track is referred to, a line number is assigned to the note indicated by the track, and the note and the line number are associated with each other. This makes it possible to determine which line belongs to each note with respect to a note on a certain track.

  Further, when the beam processing (step 1708) is completed, a drawing position information generation process is executed (step 1709). This drawing position information generation process is the same as the drawing position information generation process in step 905 of FIG.

  By executing the processing shown in FIG. 17, a line is associated with a note of a certain track, and the note graphic of the track is drawn in the same stage and in a predetermined note stem direction for each line. .

  As described above, in other embodiments, line numbers are associated with each of the notes belonging to the track to be drawn on the same stage, in order to draw the note figure of the note of the track on the same stage, The score information generating unit 14 determines the direction of the stem according to the line number. Further, when the drawing position information correction unit 16 matches the pronunciation start times for notes of different lines, if the pitch is within 2 degrees and is not the same pitch, or the same pitch and the note head or the dot If they do not match, the position information for drawing the note graphic corresponding to the note is corrected so that the note graphic of one note is moved in the horizontal direction.

  Therefore, in other embodiments, the same operational effects as the above-described embodiments of the present invention can be obtained. That is, for notes with the same pronunciation start time, if the notes have a relationship of 2 degrees (long or short 2 degrees or increment 1 degree), the drawing position of the note graphic of one note is shifted. Even if the pitches are the same, if the note heads or the dot points do not match, the drawing position of the note graphic of one note is similarly shifted. As a result, only when it is appropriate that the note figures of the two lines of notes are drawn at the same position, a note figure with a stem extending vertically from a single note head in the score is displayed. Can be expressed appropriately.

  In another embodiment, in order to draw a note figure of a track note on the same stage, a line number is associated with each note belonging to the track to be drawn on the same stage, thereby generating score information. When the note type is rest according to the line number, the unit 14 determines the position in the vertical direction to draw the note graphic corresponding to the rest. Also, the drawing one-assistance correcting unit 16 determines that, for notes of different lines, when the note type of the notes is rest and the sound lengths of the rests match when the pronunciation start times match. In order to match the drawing position of the rest corresponding to each note, the information regarding the drawing position of the musical note figure corresponding to the rest is corrected so that the musical note figure corresponding to the rest is moved in the vertical direction.

  Therefore, also in other embodiments, rest figures of the same sound length that should be at the same position in different lines are drawn in a superimposed manner. On the other hand, rest figures having different sound lengths are shifted in the vertical direction so that it is clear which line rests are clear.

  Furthermore, in the above embodiment, a line number is assigned to each track to be drawn on the same stage (step 803 in FIG. 3). Also in other embodiments, line numbers are assigned to the notes to be drawn on the same stage (step 1705 in FIG. 17). However, the present invention is not limited to these embodiments, and information indicating an association between a track and a line number and information indicating an association between a note and a line number may be stored in the storage device in advance.
