[Outline of music information display editing]
The music information display editing program executed in the music information display editing system according to one embodiment of the present invention includes a score display program and a performance data editing program, and a management for managing the operation of the entire system and operating both programs in cooperation with each other. Including programs. In this system, musical score display means for executing a musical score display program and performance data editing means for executing a performance data editing program are prepared separately, and music information (performance data elements) that the user wants to edit on the musical score display means is provided. When instructed to cause a predetermined action, the performance data editing means is activated and the performance data can be edited on the performance data editing means.

  FIG. 2 is a functional block diagram schematically showing functions of the music information display editing system according to one embodiment of the present invention, and FIG. 3 shows transition examples of display screens displayed according to the functions of the system. As shown in FIG. 2, this system includes a performance data storage unit M1 and an operation detection unit M2, and a score display unit (also referred to as “score display data generation unit”) M3 and a performance data editing unit M4 as function execution modules. Is provided.

  The performance data storage unit M1 is a functional block that stores performance data Dp to be displayed or edited. The performance data Dp is described in the SMF (Standard MIDI File) format or any other data format, is fetched from the ROM 3 or the external storage device 4 or the external devices 30 and 50, and is a predetermined storage area set in the RAM 2. Is remembered.

  The operation detection unit M2 is a functional block that detects the content of the user operation (setting operation) of the setting operator 15 and inputs the detected content to the score display unit M3 and the performance data editing unit M4. Includes functionality. This setting operation includes, for example, a specific action Ac for the music information symbol Sbs in the score display screen Ds displayed on the display 16 in FIG. 3 and an editing operation for the performance data editing window We.

  The “specific action Ac” means a predetermined action (operation technique) given to the music information symbol Sbs in the score display screen Ds in order to activate the performance data editing means M4. For the specific action Ac, for example, on the musical score display screen Ds of FIG. 3A, the music information symbol Sbs is indicated with the instruction cursor Cs operated with the mouse of the setting operator 15 and the mouse button is double-clicked. The method is adopted. In addition, the “music information” can be displayed on the score display screen Ds or the performance data editing window We by reflecting the contents of the performance data Dp, such as sound rests and various music symbols, and can be edited. An individual performance data element that can be.

  The score display unit M3 is a functional block that analyzes the performance data Dp stored in the performance data storage unit M1 and generates score display data in accordance with the score display program (SP). The action is called a “specific action”, and for example, a double click of a mouse button can be applied.) When setting operation information representing Ac is input, an activation instruction is given to the performance data editing unit M4. It has a function.

  In generating the score display data, a predetermined score display rule is applied to music information (performance data elements) in the performance data Dp so that the score display is easy to see from an aesthetic or visual point of view. Determination of direction (pitch direction) position / direction / tuplet, determination of bar line position, determination of horizontal (time direction) position (= time position) for placing musical rests and various musical symbols, each stage A number of processes are performed, such as positioning of the same-timing music information between the high-frequency staff notation (grant part) and the low-frequency part notation (fave part). Thus, since a lot of processing is required to obtain easy-to-read score display data, it takes a certain amount of time from the start of the analysis of the performance data Dp to the end of the analysis to obtain the score display data.

  The score display data generated by the score display unit M3 is output to the display circuit 7, and the display circuit 7 displays a score display screen Ds on the display 16 based on the score display data. FIG. 3A shows a display example of the score display screen Ds (however, a part of the screen Ds). In order to distinguish the display elements in the score display screen Ds from the display elements in the performance data editing window We described later (which may be expressed by “edit”), “display” is used as necessary. ", And the score on the score display screen Ds is sometimes called" display score ". Further, it is preferable that the score display screen Ds can be displayed on the entire display screen.

  The score displayed on the score display screen Ds is the same as that of a normal score publication printed on paper, as shown in FIG. It is devised so that it is easy to see and looks nice and clean. For example, the chord progression is displayed on each column score, and the bar number is displayed at the necessary place (for example, the beginning of each column score). It appears prominently in the arrangement of music information.

  For example, in a place where short notes are continuous, the interval between each note is increased to make it difficult to see the notes overlap, and in places where there are long notes or rests, the actual physical time interval is increased. The interval between notes and rests is reduced rather than the typical time interval, so that the music sheet user is not given the feeling of being extended between the notes and rests. Therefore, the scale (scale) of the time axis changes depending on the position (time position) in the time direction (that is, the time scale is indeterminate = free pitch = and the bar width is not constant), and the bar position and within the bar The position of music information such as notes does not exactly match the actual physical time position. The displayed score can be scrolled or paged, and the overall display size can be changed, but a specific area in the score can be expanded or contracted in the left / right (time) direction or up / down (pitch) direction. I can't do it.

  However, such a displayed score is easy for the score user to understand the music characteristics of the performance data Dp and has excellent visibility of the music information, so that the portion of the performance data Dp to be corrected is accurately grasped. Can do. Therefore, in this system, the performance data Dp to be edited is displayed as a score in the score display screen Ds, and the user indicates the music information symbol Sbs such as a note or a music symbol in the displayed score with the indication cursor Cs. When a specific action Ac such as a double click is performed on the instruction cursor Cs, the musical score display unit M3 activates the performance data editing unit M4, and music information corresponding to the symbol Sbs under the management of the performance data editing unit M4. (Performance data element) An editing operation can be performed on Sbe with good workability.

  Specifically, the score display unit M3 instructs the performance data editing unit M4 to start in accordance with the first specific action Ac (a), and music information (in response to the second and subsequent specific actions Ac ( ("Note / symbol") is designated (b). In response to this, the performance data editing unit M4 opens or activates an editing window (We) through which the user can edit the performance data Dp.

  The performance data editing unit M4 is a functional block for editing the performance data Dp stored in the performance data storage unit M1, and displays music information (elements) in the performance data Dp as symbols in the performance data editing window We. A function that enables editing, and instructs the score display unit M3 to update the score display on the score display screen Ds based on the performance data Dp after the editing processing after a predetermined editing process. Have.

  The staff in the performance data editing window We displayed on the display 16 through the display circuit 7 by the function of the performance data editing unit M4 is similar to the score displayed on the conventional editing screen from the viewpoint of performance data editing. The performance data Dp is displayed so as to simulate physically. FIG. 3B shows a display example of the performance data editing window We displayed corresponding to the score display screen Ds of FIG. In FIG. 3 (2), in order to avoid complexity, the display of music information such as notes in the bass staff staff is omitted. The display element in the performance data editing window We may be expressed with “Edit” as necessary, or the staff in the window We may be called “Edited staff”.

  In the edited staff, as shown in FIG. 3 (2), bar lines (vertical solid lines) Ms are arranged at equal intervals with a predetermined bar length Lm in the time direction (that is, each bar has a fixed pitch). In addition, a large number of timing grids (auxiliary lines) Gr are displayed at equal intervals between the bar lines Ms to make it easy to understand the timing positions at which symbols Sbe representing music information such as notes are arranged. In the example of FIG. 3B, the grid Gr is displayed at a time interval of 16th note length. Thus, in the performance data editing window We, the time axis scale (scale) of the edited staff is constant regardless of the time position (that is, the staff is displayed at a constant time pitch and the bar width is constant). Since the position in the time direction (time position) corresponds to the physical time, the user can easily edit the performance data Dp.

  Regarding timing, symbols such as beat timing notation [“4.1” (4th measure 1st beat) to “5.2” (5th measure 2nd beat)] are displayed outside the staff as necessary. The Next, the vertical line on the beat timing “4.1” indicates the timing cursor Cte. During editing, the vertical line can be dragged in the time direction by a user operation. The editing position at the same timing can be confirmed. The timing cursor Cte is automatically selected according to the progress of the performance data while the user operates the audition button (not shown) in the function button group at the end of the display screen to audition the performance data. The time position is moved in the direction of time to inform the user of the time position currently being played.

  The timing cursor Cts is also displayed on the score displayed on the score display screen Ds corresponding to the timing cursor Cte, and this timing cursor Cts is moved so as to follow the time position of the timing cursor Cte of the edited staff. The user can check the editing or performance position on the score display screen Ds.

  In addition, the edited staff can change the staff in the predetermined area displayed in the performance data editing window We according to the user's setting operation by the scale changing function separately provided in the performance data editing unit M4. Can expand and contract in the direction. In addition, the display position of a staff including measures and note symbols can be adjusted in the horizontal direction by operating the horizontal scroll button Bh, and can be adjusted in the vertical direction by operating the vertical scroll button Bv. Further, music symbols such as clef, key signature, tone symbol, etc. that dominate the displayed measure are displayed on the left side of the score. In the left part of the score, the time position in the left-right direction does not change, but the position in the vertical direction and the display scale change with the staff including the bars and note symbols.

  Now, when the score display screen Ds of FIG. 3 (1) is displayed on the display 16, the user wants to correct a part of the score displayed on the screen Ds, and the music information to be edited. A specific action Ac such as a double click of a mouse button is added to the cursor Cs indicating the symbol Sbs. As a result, (a) activation instruction or (b) music information instruction (“musical note / symbol” instruction) is given from the score display section M3 to the performance data editing section M4, so that the function of the performance data editing section M4 is activated. The

  When the function of the performance data editing unit M4 is activated, as shown in FIG. 3 (2), the performance data editing window We displaying the staff including the symbol Sbe corresponding to the music information is opened or activated. Thus, the performance data Dp can be edited. Note that the performance data editing window We may be displayed so as to be superimposed on the score display screen Ds so that the displayed edited score portion is not superimposed on the corresponding displayed score portion, as shown in FIG. As shown in FIG.

  When the performance data editing window We is opened or activated, the performance data editing unit M4 displays, for example, a symbol Sbe corresponding to the display symbol Sbs on which the specific action has been performed on the score display screen Ds, in red. The method highlights and informs the user that the music information corresponding to the symbol Sbe is currently designated for editing and can be edited.

  Thereafter, the user can edit the performance data Dp by correcting any music information including the symbol Sbe using the performance data editing window We, whereby the performance data editing unit M4 can perform the performance data storage unit. The contents of the performance data Dp stored in M1 are updated sequentially. Note that the score display process in the score display unit M3 takes time, and updating the score display every time data correction is performed reduces the operability. Therefore, the performance data Dp is being edited using this window We. Then, the score display unit M3 does not reflect the edited contents on the displayed score.

  Instead, the display score is displayed in the score display unit M3 when there is an instruction to update the display based on a user operation, or when the user finishes all editing operations and the editing process in the performance data editing unit M4 is completed. Update. That is, when a predetermined editing process is executed and a display update instruction is issued (c), or when the operation of the performance data editing unit M4 is completed (d), the performance data editing unit M4 displays the score display unit M3. Is instructed to update the score display, and the result of the performance data editing is reflected in the score display on the score display screen Ds.

  Next, a series of operations for displaying the score and editing the performance data will be described in order. When the user first uses the guidance screen on the display 16 to select performance data to be displayed or edited from the performance data list of the storage means 3, 4, the performance data storage unit M 1 stores the performance data. Corresponding performance data is called from the means 3, 4 and the like and stored in the performance data storage area in the RAM 2. Next, by an operation for instructing activation of the score display function, the score display unit M2 analyzes the performance data Dp to generate score display data, and the display circuit 7 replaces the guide screen with FIG. Is displayed on the display 16.

  When the user performs a specific action Ac on the musical score display screen Ds using a setting operator 14 for a musical information symbol such as a note or a musical symbol desired to be edited, the musical score display unit M3 displays performance data. An activation instruction (a) is given to the editing unit M4.

  The performance data editing unit M4 starts in accordance with the start instruction (a), immediately opens the performance data editing window We on the display 16, and edits a predetermined area including the symbol Sbe corresponding to the symbol Sbs on which the specific action Ac has been performed. The staff is displayed in the window We, and the symbol Sbe is highlighted to inform the user that the music information corresponding to the symbol Sbe is instructed to be edited. Thus, the user can edit the performance data Dp by correcting the music information of the symbol Sbe by an editing operation. Also, other music information in the performance data editing window We can be edited by designating a corresponding symbol with the pointing cursor Cs and performing a predetermined editing operation.

  A publicly known method can be arbitrarily employed for the editing operation in the performance data editing window We. For example, an icon palette in which the designated music information is dragged to another time or pitch position or outside the window We (moving or deleting music information) on the edited staff, or icons representing various types of music information are prepared. There is a method in which an icon of desired music information is designated and dragged onto an edited staff and dropped at a desired time or pitch position or dropped on music information to be changed (addition or change of music information).

  The performance data editing unit M4, after executing the editing process desired by the user, is instructed to update the display, for example, by operating a display score update button (not shown) in the function button group at the end of the display screen. In this case, this is detected, and the score display unit M3 is instructed to update the displayed score (c). In accordance with the display update instruction, the score display unit M3 displays a new display score on the score display screen Ds based on the performance data Dp of the performance data storage unit M1 updated by the editing process. The editing result can be confirmed on the display screen Ds.

  The user not only performs the editing operation by instructing the music information symbol Sbe in the performance data editing window We with the instruction cursor Cs, but also moves the instruction cursor Cs to the score display screen Ds to create a new music information symbol Sbs to be edited. It is possible to continue the editing work by performing the specific action Ac. In this case, the score display unit M3 gives the music data (“note / symbol”) instruction (b) to the performance data editing unit M4, and the performance data editing unit M4 immediately activates the performance data editing window We. An editing staff in a predetermined area including the music information symbol Sbe corresponding to the symbol Sbs is displayed, and the editing target is indicated by highlighting the symbol Sbe.

  As described above, since the processing corresponding to the display update instruction (c) and the music information (“note / symbol”) instruction (b) is independent, the user performs an editing operation while viewing the display score that is not displayed and updated. It is also possible to perform editing work while viewing a new display score after the display is updated. When the user completes all editing operations and performs an operation for instructing the end of editing, the performance data editing unit M4 ends the performance data editing process and sends a final display update instruction (d) to the score display unit. Give to M3.

  In response to this, the score display unit M3 displays a score reflecting the final result of the performance data editing on the score display screen Ds, so that the user can check the results of all editing operations. Of course, if it is desired to further correct this result, the editing operation can be resumed by adding a specific action to the music information symbol Sbs.

  When the user performs an operation to end the score display, the score display unit M3 ends the score display process, and when the edited performance data Dp is to be stored, the performance data storage unit M1 is operated by operating the save button. The performance data Dp stored in the above can be recorded in a desired storage area or storage medium of the external storage device 4, and this music information display editing process can be terminated.

  The contents of the music information display editing described above can be summarized as follows: This music information display editing system is based on the analysis of the performance data Dp, and each piece of music information (musical notes and various types) constituting the performance data Dp. A score display function M3 for displaying a score Ds [music symbol) represented by a symbol Sbs (for example, an indefinite time scale with respect to the time position (the scale of the time axis varies depending on the time position) and good visibility of music information). Then, the contents of the performance data Dp are displayed as they are on the staff We (for example, having a constant time scale regardless of the time position and good workability of editing), and editing the performance data Dp based on the editing operation on the staff We A performance data editing function M4 is individually provided. When the specific action Ac is caused for the music information symbol Sbs designated as the editing target on the score Ds, the performance data editing function M4 is activated and the performance data Dp can be edited on the staff We. In this case, the performance data Dp including the data element Sbe corresponding to the music information symbol Sbs is displayed on the staff We by the specific action Ac, and the data element Sbe is highlighted. In addition, the display of the score Ds is not updated while the performance data Dp is being edited on the staff We, but is updated only when a display update or editing end instruction is given by a user operation.

[Example of processing flow for music information display editing]
In the music information display editing system according to one embodiment of the present invention, the processing as described above can be executed in accordance with a music information display editing program including a score display program and a performance data editing program. FIG. 4 is a flowchart showing the procedure of music information display editing processing according to one embodiment of the present invention. In this system, as shown by broken lines (a) to (d) in FIG. 4, the function executed by the score display unit M3 according to the score display program SP and the performance data editing unit M4 according to the performance data editing program EP. Are linked to each other.

  In FIG. 4, when the score display program SP is activated, the score display unit M3 starts its operation. First, in step S1, the performance data storage means M1 analyzes performance data Dp prepared in a predetermined storage area of the RAM 2. Music score display data is generated according to a predetermined score display rule, and a score having an indefinite time scale with respect to the time position is displayed in the score display screen Ds on the display 16 based on the score display data.

  In the next step S2, it is determined whether or not there is a specific action Ac for music information symbols Sbs such as notes and various music symbols. If there is a specific action Ac (S2 → YES), the process proceeds to step S3. An instruction (a) for starting the performance data editing program EP is output, and a performance data element (music information) Sbe corresponding to a music information symbol Sbs such as a note or various music symbols that is the target of the specific action Ac is specified. .

  When the performance data editing program EP is activated by the activation instruction (a) from the score display section M3, the performance data editing section M4 starts its operation, and first, the performance data editing window We is opened at step E1. In the next step E2, the performance data Dp is displayed in the window We as “a score including a performance data element Sbe instructed from the score display data generation unit M3 and having a constant time scale regardless of the time position”. The editing position of the performance data Dp is moved to the position of the performance data element Sbe, and the performance data element Sbe is highlighted.

  Subsequently, in step E3, the performance data Dp is corrected / updated in accordance with the editing operation of the performance data Dp by the user. Thereafter, in step E4, it is determined whether or not a display update instruction is given by the user's update instruction operation. To do. Here, when there is a display update instruction (E4 → YES), in step E5, a display update (c) is instructed to the score display data creation unit M3 executing the score display program SP.

  When there is no display update instruction (E4 → NO) or after the display update instruction (E5), it is determined in step E6 whether or not there has been an instruction to end the performance data editing program EP by the user's end operation. . If there is no instruction to end the program (E6 → NO), the process returns to step E3, the processing operations of steps E3 to E6 are repeated, and the editing process of the performance data Dp is continued.

  When the user completes the editing operation and operates the program end instruction (E6 → YES), the process proceeds to step E7, and the display update instruction (d) is sent to the score display section M3 executing the score display program SP. And the performance data editing program EP is terminated.

  On the other hand, in the score display section M3, when there is no specific action Ac (S2 → NO) or after an instruction (S3) of the performance data element Sbe, the process proceeds to step S4 and a display update instruction (c) is sent from the performance data editing section M4. , D) is determined. When a display update instruction is given (S4 → YES), in step S5, the performance data Dp updated in the editing process (E3) in the performance data editing unit M4 is analyzed, and the score in the score display screen Ds is analyzed. Update the display.

  When there is no display update instruction (c, d) (S4 → NO) or after the display score update (S5), it is determined in step S6 whether or not there is an instruction to end the score display program by the user's end operation. To do. If there is no instruction to end the program (S6 → NO), various score display control processes are performed on the score display screen Ds in step S7, and the process returns to step S2 to perform the score display processing operations in steps S2 to S7. repeat. Note that various musical score display control processes in step S7 include, for example, page turning and display size change.

  Further, when it is determined that the specific action Ac has occurred when returning to step S2 (S2 → YES) and the process proceeds to step S3, the performance data element corresponding to the music information symbol Sbs that is the target of the specific action Ac ( Music information) Sbe is instructed to the performance data editing unit M4 (b). In response to this instruction (b), the performance data editing unit M4 immediately executes the display process of step E2.

  In other words, while the performance data editing window We is opened (E1) while the performance data Dp is being edited, the music information (notes / symbols) at other positions is specified on the score display section M3 (program SP) side. It is also possible to shift to editing of performance data elements at other positions by causing the action Ac. In this case, as described above, the performance data editing window We is not newly opened, and only the editing position (the edited staff part to be displayed) is moved.

  Then, when the user confirms the content of the final performance data Dp after the completion of the editing work based on the score displayed on the score display screen Ds updated in step S5, and operates the program end instruction (S6 → YES) ), The score display program SP is terminated.

[Various Embodiments]
The preferred embodiment of the present invention has been described above with reference to the drawings. However, this is merely an example, and the present invention can be variously modified without departing from the spirit of the invention. For example, with respect to the edited staff, in the embodiment, the performance data editing unit M4 displays performance data in a musical score display format such as a staff score, and accepts editing. It may be an event list format. Those formats are also included in the “staff” of the present invention.

  When displaying performance data in the score display format in the editing window, the left and right direction (time direction) can be expanded and contracted so that the density of notes can be reduced even in densely packed parts. Is desirable. Similarly, it is further preferable that the vertical direction (pitch direction) is also extendable. These matters can be similarly applied to the piano roll format.

  The specific action (Ac) for the music information symbol (musical note, various music symbols, etc.) to be edited on the score display screen is not limited to the double click with the mouse as in the embodiment. “Click with mouse (single)” + “operation with other controls (eg, enter key)”, “click with mouse” + “select“ edit ”command from menu”, or mouse Other pointing devices (track points, touch pads, joysticks, etc.) may be used, and if the display unit is an electronic music device provided with a touch panel, the operation of the touch panel may be used.
