[0010]
When the performance data is automatically played on the computer device 1, the performance data of the musical sound reproduced by the tone generator circuit 17 is read from the external storage device 16 together with the score data in the form of bitmap format corresponding to the performance data. And temporarily stored in the RAM 13. The CPU 10 interprets the performance data to generate a sound generation parameter, and supplies the sound generation parameter to the sound source circuit 17. As a result, the musical sound obtained by reproducing the performance data generated by the tone generator circuit 17 is emitted from the sound system 5. At the same time, the score data is supplied to the display circuit 15, and the score data corresponding to the performance data is displayed on the display 4 by the display circuit 15 as shown in FIG. In this case, as shown in FIG. 3, the cursor C is moved on the musical score data in synchronization with the progress of the performance data. Further, the bus 18 is a bus for exchanging information between the blocks.
The hardware configuration of the computer apparatus 1 described above is the same as that of a personal computer or workstation.
[0011]
Next, a display position information creation method according to the present invention that is performed by the computer apparatus 1 shown in FIG. 1 will be described.
As shown in FIG. 3, the display position information creation method according to the present invention includes a cursor C that moves on the musical score data graphically displayed on the display 4 in synchronization with the progress of the performance data corresponding to the musical score data. This is a method of creating display position information. An example of the data structure of the performance data is shown in FIG. The performance data is filed MIDI data or the like, and is constituted by alternately arranging duration data indicating a time interval between events and event data. Events include note messages that send note-on and note-off, control messages that send information for controlling musical sounds, exclusive messages that send manufacturer-specific data and other data. Further showing the data structure of the note message, the note message is composed of a channel number indicating the channel number to be sounded, a note number indicating the pitch to be sounded, and gate time information indicating the sounding length.
[0012]
When performing the display position information creation method according to the present invention, the computer apparatus 1 selects performance data for which cursor display position information is desired to be played. That is, the selected performance data is read from the external storage device 16. At this time, the musical score data, which is image data such as a bitmap format corresponding to the performance data, is also read. The read performance data is stored in the work area of the RAM 13, the score data is supplied to the display circuit 15, and the score data corresponding to the performance data is displayed graphically on the display 4 by the display circuit 15 as shown in FIG. It becomes like this.
[0013]
If the read performance data has the data structure shown in FIG. 2, the CPU 10 interprets the first event 1 data of the performance data, and if the event 1 data is a note message, the tone generation parameter is set. And waits until the time indicated by duration 1, which is the sound generation timing, elapses. Then, when the time indicated by duration 1 has elapsed, the progress of the performance is stopped. At this time, the cursor C displayed on the display 4 is displayed at the initial position, but the cursor C is not always displayed on the first note corresponding to the event 1 in the musical score data displayed graphically. . Therefore, the mouse 3 is operated, the pointer is placed on the first note, and the mouse 3 is clicked. As a result, the cursor C moves to the clicked position. In this case, the cursor C is displayed on the first note. When the cursor C is displayed at a predetermined position, the key corresponding to the note on the operation element 2 or any key is pressed. In response to this, the CPU 10 supplies a tone generation parameter corresponding to the data of the first event 1 to the tone generator circuit 17. As a result, the musical sound obtained by reproducing the event 1 data generated by the sound source circuit 17 is emitted from the sound system 5. At the same time, the coordinate position data of the cursor C on the display screen of the display 4 is temporarily stored in the work area of the RAM 13 together with the timing information when the performance is stopped (the time when the duration indicated by duration 1 has elapsed). When the time indicated by the gate time information in event 1 elapses, the CPU 10 sends the note-off data to the tone generator circuit 17 to stop the musical sound.
[0014]
Next, the CPU 10 reads out the next duration 2 data and the event 2 data from the performance data, interprets the event 2 data, and generates a sound generation parameter if the event 2 data is a note message. It waits until the time of duration 2 which is timing elapses. In this standby state, the cursor C is displayed so as to move in the direction shown in FIG. Then, when the duration 2 has elapsed, the progress of the performance is stopped. At this time, the cursor C displayed on the display 4 is not necessarily displayed on the note corresponding to the event 2 in the musical score data displayed graphically. Therefore, the mouse 3 is operated, the pointer is placed on the note corresponding to the event 2, and the mouse 3 is clicked. As a result, the cursor C moves to the clicked position and is displayed on the note corresponding to the event 2. When the cursor C is displayed at a predetermined position, the key on the operation element 2 is pressed. As a result, the CPU 10 supplies the sound generation parameter corresponding to the data of the event 2 to the sound source circuit 17. As a result, the musical sound obtained by reproducing the data of event 2 generated by the sound source circuit 17 is emitted from the sound system 5. At the same time, the coordinate position data of the cursor C on the display screen of the display 4 is temporarily stored in the work area of the RAM 13 together with the timing information of the time when the time indicated by duration 2 has elapsed. When the time indicated by the gate time information in event 2 elapses, the CPU 10 sends the note-off data to the tone generator circuit 17 to stop the musical sound.
[0015]
In this way, every time the time indicated by the duration data in the event of the note message is reached, the progress of the performance is stopped, and the display position of the cursor C is adjusted to be positioned on the corresponding note of the musical score data displayed graphically. Thus, the cursor display position information can be created. As shown in FIG. 4, the cursor display position information includes coordinate position data of the X and Y coordinates of the cursor C on the display screen, elapsed time information from the start of performance, which is timing information when the performance is stopped, and And is temporarily stored in the work area of the RAM 13 as cursor display position information for each note in the musical score data displayed graphically. When the performance data is finished and the cursor display position information corresponding to all the notes in the score data is created, the cursor display position information temporarily stored in the RAM 13 is stored in the external storage device 16 as a file. can do.
[0016]
In this way, the performance is stopped at each sounding timing, and the cursor display position information can be easily adjusted by adjusting the display position so that the display position of the cursor is positioned on the note corresponding to the tone to be played. And can be created accurately. The display position can be adjusted by placing the pointer on the displayed note and clicking the mouse 3 to adjust the display position of the cursor on the note. Thus, according to the display position information creation method of the present invention, the cursor display position information can be created easily and accurately in a short time.
[0017]
By the way, when the performance data is selected and automatically played, the corresponding cursor display position information is read together with the score data, and the cursor C moves on the score-displayed graphic data in synchronization with the progress of the performance. It is displayed to go. At this time, the cursor C is always displayed on the corresponding note in the musical score data displayed graphically at the timing when the musical sound is generated.
In addition, the speed at which the cursor C moves between adjacent notes in the musical score data displayed graphically is constant. For this reason, the CPU 10 calculates the difference in elapsed time from the start of performance of the cursor display position information in adjacent notes, and sends display data interpolated between them to the display circuit 15, so that the cursor C is adjacent on the display 4. It is displayed to move between notes at a constant speed. However, the speed of movement between adjacent notes varies depending on the type of adjacent notes and the display interval between the notes.
[0018]
Further, as shown in FIG. 3, when the musical score data is displayed in two stages, a note that appears when the cursor C is moved regardless of the upper part (high part) and the lower part (low part). Each time, the cursor display position information is created. That is, as shown in FIG. 3, the cursor display position information for displaying the cursor C at the position C1 on the upper and lower notes is created by placing the cursor C at the position C2 displayed on the lower note. The cursor display position information to be displayed is generated, and the next created is the cursor display position information for displaying the cursor C at the position C3 displayed on the upper and lower notes.
[0019]
Next, the display position information creation method according to the present invention will be described with reference to the functional block diagram shown in FIG.
In FIG. 5, when creating the cursor display position information, the corresponding performance data is selected and read from the external storage device 16 (S1). At this time, the musical score data, which is image data such as a bitmap format corresponding to the performance data, is also read from the external storage device 16 (S7). The read performance data is stored in the work area of the RAM 13, and the score data is supplied to the display screen creation section (S8) of the application program, and the score data display screen data corresponding to the performance data is created. As shown in FIG. 3, graphic display is performed on the display 4 which is a screen display unit through the display circuit 15 (S9).
[0020]
The read performance data is taken into the CPU 10 constituting the performance section, and the first event data is interpreted. When the event data is a note message, a sound generation parameter is generated. Next, it waits until the time indicated by the duration, which is the sound generation timing, elapses. Then, when the time indicated by the duration has elapsed, the progress of the performance is stopped. At this time, in order to display the cursor C displayed on the display 4 on a note corresponding to the event in the musical score data displayed graphically, the user clicks the mouse 3 with the pointer set to the note (S5). . Thereby, the display position of the cursor C moves onto the note, and cursor display position information for displaying the cursor C at the clicked position is created (S6). The cursor display position information is supplied to the display circuit 15 which is a display screen creation unit (S8), and the cursor C is displayed on the corresponding note of the score data displayed graphically on the screen display unit ( S9).
[0021]
If the cursor C is displayed off the corresponding note of the musical score data displayed graphically on the screen display unit, the mouse 3 is clicked again with the pointer over the corresponding note (S5). ) To adjust the display position of the cursor C. By repeating such an operation, the cursor C can be displayed on the corresponding note. When the cursor C is displayed at a predetermined position, when a key on the operation element 2 is depressed, the detection circuit 14 which is a keyboard input detection unit detects the key depression, and the tone generation parameter generated by the CPU 10 indicates the performance unit. It is supplied to the tone generator circuit 17 which comprises. Thereby, the musical sound which reproduced | regenerated the data of the event produced | generated by the sound source circuit 17 is emitted from the sound system 5 (S3). At the same time, cursor display position information for displaying the cursor C on the note corresponding to the reproduced musical sound is determined. As shown in FIG. 4, this cursor display position information is composed of coordinate position data consisting of the X and Y coordinates of the cursor C in the screen display section, and elapsed time information from the start of performance, and is temporarily stored in the work area of the RAM 13. Saved (S6). When the time indicated by the gate time information in the event elapses, the CPU 10 sends the note-off data to the tone generator circuit 17 constituting the performance unit, and stops the musical sound (S3).
[0022]
Next, by repeating the same operation, cursor display position information for displaying the cursor C on the corresponding notes of the musical score data displayed graphically corresponding to each musical tone when the performance data is played is created one after another. be able to. When the performance data is finished and the cursor display position information corresponding to all the notes in the score data is created, the cursor display position information corresponding to each note temporarily stored in the RAM 13 is externally stored as a file. It can be stored in the storage device 16. Thereby, the cursor display position information can be created easily and accurately in a short time.
