It is a MIDI interface circuit for passing in the network. These elements are connected to each other by a bus as shown in the figure.

  FIG. 2 is a diagram showing an example of a score to be edited. In this figure, 21 is a score display frame showing the size of the area displayed in the score display window opened on the display device 3 when this score display control program is started. Of these, only the part surrounded by 21 is displayed. Here, musical notes and other musical symbols are displayed as musical score elements. Among these musical symbols, there are multiple musical notes such as ties, slurs, slides, choking, hammering on, etc. There are musical score symbols (hereinafter also referred to as “concatenated symbols”) and other symbols. The present invention is characterized by the processing of concatenated symbols. Hereinafter, the displayed notes are referred to as note events, and the concatenated symbols are referred to as symbol events.

A pen-type icon 22 in the figure is an icon for selecting and instructing an event to be edited, and is used for selecting the target event with the mouse and deleting or moving the position. The position on the display screen can be controlled. Then, the icon 22 is moved to the position of an event such as a note to be moved, the event to be moved is determined by right clicking the mouse, moved to a desired position, and then the right click is released. The desired event can be moved. Further, it is possible to designate a position where a note in the score is to be arranged with this icon 22 and add an arbitrary note there.
Further, 23 is a notation representing a musical score symbol. Here, a slide (a stringed instrument such as a guitar, picking a string by pressing a string, and then moving the finger while sliding it to the left or right with the sound as a base point) Shows how to change the pitch up and down).

FIG. 3 is a diagram showing a data structure of music information corresponding to the score shown in FIG. As shown in this figure, the music information is composed of music information (performance data) 30 shown in FIG. 3A and symbol information 40 shown in FIG.
The music information (performance data) 30 shown in FIG. 3A is in SMF (standard MIDI file) format in which timing information and information indicating performance events (or symbol events) are sequentially stored as the music progresses. Following the initial setting information 31 for setting the tempo, tone color, etc. of the music, performance event information 33 including symbol information, timing information 32, key-on data 34, step time data 35, and gate time data 36, symbol event information 37 are sequentially stored. Here, the key-on data 34 indicates a key number indicating the pitch of the note, the step time data 35 indicates the number of clocks indicating the note length of the note, and the gate time data 36 indicates the actual pronunciation of the note. The number of clocks indicating the time length is specified. In the present embodiment, the length of one bar is 96 clocks, and the value of timing data in each of the information 32 and 34 to 36 is a value that is reset to zero for each bar.
The symbol event information 37 is data for the symbol event in the musical score, and pointer information indicating the recording position of the symbol information shown in FIG. 3B, which is the substance of each symbol event, is recorded here.

FIG. 3B shows the structure of the symbol information. As shown in FIG. 3, the symbol information is composed of a symbol event name 41, symbol data 42, and performance data 43.
The symbol data 42 and performance data 43 will be described with reference to FIG. Here, the score shown in FIG. 2 is taken as an example, and the case of slide-up as a symbol event is shown.
As shown in FIG. 4, at the beginning of the symbol data 42, template instruction data 51 is provided for designating a template for giving an effect corresponding to the musical score symbol to the performance data. The timing information and performance events (note data 52) of the notes to be played are sequentially stored, and finally the return code 53 is stored.

  The performance data 43 is performance data that is referred to when actually performing an automatic performance, and is performance data in which an effect corresponding to the symbol is given to the symbol data 42. That is, the performance data 43 that can express the effect corresponding to the symbol is created by applying the template specified by the template instruction data 51 to the note data 52 in the symbol data. In the example shown in FIG. 4, a slide-up template is designated, and this template has a characteristic that the pitch increases as time passes. By applying this template to the note data 52 in the symbol data 42, the pitch change by the pitch bend is performed after the performance event of the key number 64, the step time 24 and the gate time 44 at the timing of 48 clocks (the third beat). Thus, a plurality of timing information and pitch bend event data are created so that the pitch of the key number 65 is reached at the timing of 72 clocks (fourth beat). Thereby, performance data 43 having a slide-up effect is created.

The music score edit display process executed using such music information and the above-described score display screen will be described with reference to the flowchart of FIG. As described above, since this embodiment is activated when the score mode is set in the sequence program, the score mode processing will be described.
When the musical score mode process is started, first, in step S1, the musical score is displayed on the display device 3 based on the music information selected in the music selection process in the main process of the sequence program. As described with reference to FIG. 2, this score is displayed in the score display frame 21, and only as many scores as can be displayed in the frame 21 are read from the song information 30 from the beginning position of the song information 30. Is displayed. That is, the position of the note in the measure (how many beats) is determined by the timing information 32 in the music information 30, and on the staff notation corresponding to the pitch of the note by the key-on data 34 in the performance event information 33. The position of the note is determined, the type of the note is determined by the step time data 35, and is displayed in the score display window. When the symbol event information 37 is read, the notes included in the symbol event are displayed by the note data 52 in the corresponding symbol information 40 in the same manner as described above, and the template instruction data 51 of the symbol data 42 is used. An icon corresponding to the symbol event (in the case of a slide, an arc line and a character “s.”) Is selected and displayed in association with a note included in the symbol event.
In this manner, by separately displaying display data (symbol data) and performance data (performance data) as symbol information, accurate correspondence between the score display and the music performance can be easily obtained, Ability can be improved.
When a new musical piece is selected, a blank musical score is displayed.

  Next, proceeding to step S2, it is determined whether or not a display event moving operation has been performed. That is, as described with reference to FIG. 2, whether a desired musical score event is dragged by the user's mouse operation using the pen icon 22 and moved to a desired position, and which event is performed. It is determined whether is dragged. This moving operation can be performed in any direction on the screen. Further, the moving event may be displayed in a mode (for example, red) different from the display of the normal state (for example, black).

When there is no event moving operation and the determination result in step S2 is NO, the process proceeds to step S4 and other editing processes are performed. On the other hand, when the moving operation is detected, the process proceeds to step S3, and after the corresponding moving process is performed, the other editing process of step S4 is performed. Details of this movement process will be described later.
In the other editing process in step S4, editing processes such as addition and deletion of note events and symbol events, and changes of various parameter values are performed in response to user operations. Since this is the same as a normal score clearing software, a detailed description is omitted.
When the user performs an editing process such as adding, deleting, or moving a note event during editing, rests are automatically inserted and deleted in accordance with the process.

  Next, it progresses to step S5 and an automatic performance process is performed. In the vicinity of the score display window, buttons such as music playback, playback stop, and return to the start position are provided, and this automatic performance processing is executed when the user instructs playback. This automatic performance process is performed by sequentially reading the music information 30 to be edited and processing the corresponding performance event information 33 at the timing based on the timing information 32. However, when the read data is the symbol event information 37, the performance data 43 recorded in the symbol information 40 indicated by the symbol event information is sequentially read from that point. Then, when the return data 53 is read, the process returns to reading the data in the music information 30, and the data recorded next to the symbol event information 37 read this time is read. A musical tone control signal corresponding to the performance event information sequentially read out in this way is sent to the sound source device 5 to perform automatic performance.

  Next, it progresses to step S6 and it is determined whether the tablature display instruction | indication was made. This is because the operation of clicking the switch (software switch) for instructing the tablature display provided on the display screen with the mouse or the like, or the tablature display by the user via the pull-down menu etc. This is determined by detecting that the instructing operation has been performed. If an operation for instructing the tablature display is not detected, the process proceeds to step S8, where it is determined whether or not there is an instruction to end the score mode. If there is no instruction, the process proceeds to step S2 again to select The processing for the currently displayed score is continued. If there is an instruction to end the music score mode process, the process returns to the main process.

  On the other hand, if there is a tablature display instruction, the process advances to step S7 to change the score display based on the currently displayed staff notation to tablature display. The details of the tablature display process will be described later. As a result, the corresponding tablature is displayed on the display screen. At this time, the tablature may be displayed so as to correspond to the performance position of the staff in the score display window where the staff was displayed, or a new tablature display window may be opened. .

Next, the movement process will be described with reference to the flowchart of FIG. 6 and the movement examples shown in FIGS.
When the movement process is started, first, a process of automatically scrolling the score on the screen in accordance with the movement of the event is performed until the event movement operation ends (steps S11 and S12). As a result, when the position of the dragged event (hereinafter referred to as “movement event”) is likely to protrude from the display screen, the musical score displayed on the screen is scrolled. That is, when the coordinate position on the screen of the movement event reaches the end of the screen, the reading start position of the music information 30 is changed. Note that the score scrolling process is not limited to the movement process, and is also executed by the user operating a scroll bar arranged in the vicinity of the score display screen.

  In step S12, when it is detected that the drop operation for the movement event has been performed and the movement operation has been completed, the process proceeds to step S13, where the performance data corresponding to the movement event and the position after the movement are displayed. The corresponding recording position is detected. That is, the performance data corresponding to the movement event is detected in the music information 30 and stored in a buffer or the like, and the moved position of the movement event is detected from the coordinates on the display screen. Then, it detects which recording position in the music information 30 corresponds to it, and stores the position information (timing information) in the buffer.

  Then, the process proceeds to step S14, and it is determined whether or not the moving operation is related to a connection symbol. Here, when the movement event is (1) a note event included in the symbol information, (2) when the recording position after the movement of the normal note event is in the symbol information representing the connected symbol, or (3) If a note event included in the symbol information is included in the concatenated symbol as a result of moving the note event included in the symbol information, this step is regarded as related to the concatenated symbol. The determination result in S14 is YES.

In other cases, the determination result is NO, the process proceeds to step S21, and processing for changing the contents of the music information 30 based on the moving operation is performed. That is, the performance data corresponding to the movement event stored in the recording position before movement in the music information 30 is deleted and recorded in the detected recording position after movement.
Further, the timing information is corrected so as to correspond to the recording position. Then, the process proceeds to step S22, and the score is displayed on the score display screen as described above (normal display) based on the changed music information 30 as described above.

  On the other hand, when the moving operation is related to the connected symbol and the determination result in step S14 is YES, the process proceeds to step S15, and the contents of the music information 30 and the symbol information 40 are changed based on the movement. . That is, in this case, since the movement event is related to the connected symbol, the symbol information 40 is rewritten. In addition, as described in (3) above, when a moving event is information in a concatenated symbol and a new event is included in the concatenated symbol due to the movement, the event that is newly included Is deleted from the music information and added to the symbol information, and the music information 30 is also changed.

  In step S16, it is determined whether or not the template instruction data 51 needs to be changed. That is, it is determined whether or not the template specified by the current template instruction data 51 corresponds to the contents of the new note data rewritten in step S15. For example, if a note event located at the back of the note events connected by slide-up is moved and the key number is lower than the note event in front, the slide-down will be replaced with a new slide-down. It corresponds to a special note event. Therefore, it is necessary to change the template instruction data.

If it is determined in step S16 that the template instruction data needs to be changed, the process proceeds to step S17, where the contents of the template instruction data 51 are changed based on the new note data. That is, the content of the template instruction data 51 is changed to data indicating an optimum template for the edited note data in accordance with the change tendency of the pitch (note) and the content of the previous instruction template. For example, when the previous instruction template is a slide-up and the pitch change tendency is reversed, the correspondence is determined in advance so that the slide-down becomes new template instruction data. Based on this, the template instruction data 51 is changed.
After step S17 is completed or when the template instruction data does not need to be changed and the determination result in step S16 is NO, the process proceeds to step S18. In step S18, the content of the performance data 43 in the corresponding symbol information is rewritten based on the symbol data 42 changed in step S15. As a result, the result of the editing operation can be reflected during the automatic performance described above.

Next, proceeding to step S19, it is determined whether or not the note events linked to the movement event cannot be simultaneously displayed on the same display screen. That is, since the display screen is scrolled in accordance with the movement of the movement event as described above, depending on the movement amount, the connected event may not be visible on the display screen.
All the note events connected on the display screen can be displayed at the same time. When the result of the determination in step S19 is NO, the process proceeds to step S22, and the score is normally displayed based on the changed information.

  On the other hand, when the note events linked to the movement event cannot be simultaneously displayed on the display screen, the process proceeds to step S20, where the linked display is changed to the special display and displayed. That is, the display of a connected symbol in a form different from the normal connected symbol is displayed near the note event displayed on the display screen (this is one of the notes connected by the connected symbol). To make it possible for the user to clearly understand the connection symbols. As a form of this special display, a character indicating the content of the concatenated symbol is displayed near the note included in the concatenated symbol displayed on the screen, and an arc line to the other note not displayed on the screen. Is displayed only partially. Thus, the user can clearly grasp the contents of the connected symbol and can display easily because it does not display a long arc line.

The above movement process will be described more specifically based on the movement examples in FIGS. 7 and 8. In this example, before the movement, the example of the music information shown in FIGS. 2 to 4 is the music information before the movement, and after the movement, the state shown in FIG. 7 or FIG. To do.
7 moves the fourth quarter note in the vicinity of the pen icon 22 in FIG. 2 to the second beat (24 clock timing) and moves the pitch to the key number 71 position. FIG. 7A shows the musical score after the movement. As is clear from this figure, in the case of this movement operation, the slide-up before the movement is changed to the slide-down after the movement. Since the rest is automatically inserted as described above, the rest position is changed in accordance with this movement.

7B shows the symbol data 42 after movement, FIG. 7C shows an example of the instruction template after movement, and FIG. 7D shows the performance data 43 after movement, where the dark portion is changed. Is shown. Since this movement is a movement within a concatenated symbol, the music information is not changed.
That is, in this example, as shown in FIG. 7B, in step S15 of FIG. 6, the note event (key number 71) corresponding to the timing (24) before the timing (48) of the symbol data 42 is obtained. Is added. This added event is an event moved by a mouse operation. In step S16, it is determined that the template instruction data needs to be changed. In step S17, the template instruction data 51 is changed from slide-up before movement to slide-down. In step S18, the performance data 43 is changed. That is, a new performance shown in FIG. 7D is applied to the symbol data 42 by applying a slide-down template corresponding to the changed template instruction data 51 shown in FIG. Data 43 is generated. In the illustrated example, a plurality of timing information and pitch bend event data reaching the key number (64) from the key number (71) is generated based on the symbol data 42 updated by the event movement, and the performance data corresponding to the slide that tends to be down. 43 is generated.
In step S22, a score based on the changed information is normally displayed. That is, the note after the position change and the corresponding concatenated symbol, in this case, the slide down are automatically displayed.

  In the example shown in FIG. 8, in the score displayed as shown in FIG. 2, the note event of the fourth beat in the vicinity of the pen icon 22 is increased to the right with the pitch unchanged (the next measure). It shows the case of moving to the third beat). In this case, the screen display position is scrolled by the movement of the event, and the other note connected to the movement event protrudes from the display screen 21 and cannot be displayed simultaneously with the movement event. Accordingly, the determination result in step S19 in FIG. 6 is YES, and the process proceeds to step S20. As shown in FIG. 8A, the linked display (slide up in this case) is a special display (slur in the slide display). Is displayed only in the right half, and the letter “s.” Indicating the slide is displayed in the lower part thereof. Thereby, the display is easy to understand for the operator.

8B shows the symbol data 42, and timing (0) is added to indicate that the event of timing (72) is the position of timing (72) of the next measure. . That is, it can be said that this timing (0) indicates a bar line. Since the slide tendency has not changed, the template instruction data 51 has not been changed.
Further, FIG. 8C shows the performance data 43. Based on the symbol data 42 updated by the event movement, the length of time for the end of the slide is changed to the gate time GT (140), corresponding to it. Thus, it can be seen that the pitch bend event that gives the sliding tendency and the contents of the timing information are also newly created and recorded.

  Note that when the notes that are connected by scrolling the score display screen can no longer be displayed at the same time, the process of changing the display of the connected symbols to a special display is displayed not only when the event is moved but also by the user The same can be said for the case where scrolling is performed using a scroll bar or the like in order to change the range of the musical score.

Next, the tablature display process (step S7 in FIG. 5) will be described with reference to the flowchart of FIG. 9 and the display example of FIG.
When this tablature display process is started, first, a reading start position is set in step S31. That is, when a tab score display instruction is given, an event (music information 30 or symbol information corresponding to the head position of the currently displayed score is displayed in order to display a tab score corresponding to the score section displayed at that time. 40) is set as the reading start position.

In step S32, data for one event is read from the reading start position. At this time, for normal performance data, performance data for one pronunciation (timing information 32 and performance event information 33) is read out as data for one event. Read as one event.
In step S33, the note number (Kon) included in the read performance data or symbol information for one event is converted into a corresponding fret number. This conversion reads out the string and fret number corresponding to the note number in the read event with reference to the conversion table that describes which fret of which string corresponds to each note number. Is done.

  Subsequently, when the read event is a symbol event, the process proceeds to step S35, and it is determined whether or not the symbol event is an event to be specially displayed with reference to the corresponding template. Here, the symbol event is choking (playing a stringed instrument such as a guitar. After playing a string and picking it, the string being pressed is pushed up or down with a finger in the vertical direction to change the pitch), arming (to an electric guitar) When using the attached tremolo arm, the pitch of all strings is raised or lowered), etc., so that the played fret position does not change even if the pitch changes. The result converted by the conversion table cannot be used as it is, and is determined to be a symbol event to be specially displayed. Further, as will be described later in Example 4 (FIG. 10), even in the case of a predetermined symbol event subsequent to the choking or arming, it is determined that the symbol event should be specially displayed.

If the read symbol event is an event to be specially displayed and the determination result in step S35 is YES, the process proceeds to step S36, and the fret number for the special display event is determined according to the content of the symbol event. Reconvert to That is, a plurality of fret numbers present in the read symbol event are converted into fret numbers that match the symbol (playing style) according to a predetermined rule. This reconversion rule is defined in advance for each symbol event to be specially displayed.
In step S37, the fret number or symbol is displayed at a corresponding position on the tablature.

  Also, when the read event is a normal event (when the determination result of step S34 is NO), and when the read event is not an event that should be specially displayed (the determination result of step S35 is If NO, the process proceeds to step S37, and the fret number converted using the conversion table in step S33 is displayed as it is at the corresponding position on the tablature. Here, examples of the symbol event that does not require the special display include hammering on, pulling, trill, and slide.

FIG. 10 is a diagram showing examples of tablature display. Example 1 shows a case where the read symbol event is choking, where the fret numbers are set to 2 and 3 in step S33. In step S36, the fret numbers 2 and 2 and the re-converted fret number are displayed.
Example 2 shows conversion to hammering-on tablature display without special display. In this case, the fret numbers are 2, 3 as output from the conversion table in step S33.
Example 3 shows a case where choking continues, and it can be seen that three musical scores are aligned to the minimum fret number.
Furthermore, Example 4 shows a case where choking and hammering-on are continuous. The choking portion is aligned with the minimum fret number as described above, and the hammering-on portion continuing to the choking is The fret number is shifted by an amount corresponding to the pitch difference from the immediately preceding note. As described above, when the hammering-on is followed by the choking, it is determined that the symbol event is to be specially displayed in step S35, and the fret number is reconverted for the hammering-on. ing.
Thus, according to the present invention, it is possible to perform more accurate tablature display.

  In the above note event moving process, if the musical score symbol assigned to the note event to be moved is a choking symbol, the pitch before choking is higher than the pitch after choking. It is recommended that the movement of the note event be controlled so that it does not occur. As a result, it is possible to prevent a musical score symbol from being added. Even if such movement control is not performed, the template related to choking may be interpreted as choking by the same pitch without changing the template. Alternatively, the choking symbol may be automatically deleted when a movement not suitable for choking is made.

Further, in the above-described embodiment, the score display control program started from the score mode of the sequence software has been described. However, the present invention is not limited to a score clearing program, a single score display editing program, or a single score display device. Can be realized in exactly the same way.
Furthermore, the form of the special display of the above-described score symbols is not limited to the form described above. For example, a number or letter is assigned to the choking symbol, or a specific display color is attached to indicate which musical notation symbol is related, such as making it easy to understand the notes connected by the same choking symbol. You may do it.

Furthermore, the sound source device or the MIDI device 5 described above is a device in which each device is connected as a separate device using communication means such as MIDI or various networks, or in the form of a personal computer + application software. Also good.
Furthermore, the format of the performance information is “event + relative time” in which the time of occurrence of the performance event is represented by the time from the previous event, and the time of occurrence of the performance event is represented by the absolute time in the song or measure. “Event + absolute time”, “pitch (rest) + note length” representing performance data in terms of note pitch and note length or rest and rest length, and a memory area for each minimum performance resolution Any format may be used such as a “solid method” in which performance events are stored in a memory area corresponding to the time at which the performance event occurs.
Furthermore, the score display program of the present invention may be stored in a server computer or the like connected via the communication network 4 and downloaded to the personal computer 1 for use as necessary.
