DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described.
[0010]
FIG. 1 is a block diagram of an electronic musical instrument in which a score display device according to an embodiment of the present invention is incorporated.
[0011]
The electronic musical instrument 10 shown in FIG. 1 includes a CPU 11, a RAM 12, a ROM 13, a tempo clock unit 14, an operator group 15, a floppy disk drive 16, a display unit 17, and a sound source 18. . The CPU 11, RAM 12, ROM 13, tempo clock unit 14, operator group 15, floppy disk drive 16, display unit 17, and sound source 18 are connected by a data bus 19. A speaker 180 is connected to the sound source 18.
[0012]
The CPU 11 reads out the program stored in the ROM 13 via the data bus 19 and performs various processes.
[0013]
The RAM 12 stores music data transferred from the floppy disk drive 16, various flags, and the like.
[0014]
The ROM 13 stores a program for controlling the entire electronic musical instrument 10 shown in FIG.
[0015]
The tempo clock unit 14 generates a tempo clock interrupt at a tempo instructed by the CPU 11, that is, at a timing (tick) obtained by dividing a quarter note into 96 equal parts. This tempo clock interrupt becomes a basic clock for performing automatic performance and the like.
[0016]
The operating element group 15 is provided with a plurality of switches for setting various states of the electronic musical instrument 10 shown in FIG.
[0017]
The floppy disk drive 16 controls a floppy disk 160 inserted from the outside of the electronic musical instrument 10. The floppy disk 160 stores a plurality of pieces of music data divided into a plurality of tracks. For example, accompaniment data is stored in the second track, and performance data for the left hand is stored in the third track. The fourth track stores right-hand performance data, and the tenth track stores rhythm data. The first track stores performance data played by the performer.
[0018]
The display unit 17 corresponds to display means according to the present invention, and displays a musical score played by the performer for a plurality of measures and changes the display in accordance with automatic accompaniment.
[0019]
The sound source 18 emits a musical tone having a pitch specified by the CPU 11 through the speaker 180 into the air.
[0020]
The electronic musical instrument 10 configured as described above incorporates a display unit 17 and a score display device including a control unit by the CPU 11 and the ROM 13, and the control unit by the CPU 11 and the ROM 13 starts playing by the performer. When a plurality of automatic accompaniment is performed before the performance, the musical score played by the performer is displayed on the display unit 17 while skipping display of at least some of the plurality of measures.
[0021]
In this electronic musical instrument 10, first, the performer inserts a floppy disk 160 into the floppy disk drive 16, and selects music data to be played from a plurality of music data stored in the floppy disk 160 with the operator group 15. Specify by operating. The designated music data is transferred to the RAM 12.
[0022]
Next, the performer operates the operator group 15 to select whether to perform with both hands, left hand, or right hand from the designated music data. Furthermore, the performance start position, whether to play from the first measure or from the middle measure, is selected. In this embodiment, only automatic accompaniment is performed from the first bar to the third bar. Here, a starter (not shown) of the operator group 15 is pressed by the performer. Then, the routine shown in FIG. 2 is started.
[0023]
FIG. 2 is a flowchart showing a timer routine started by a tick when the start switch is pressed.
[0024]
First, in step S1, the bar position of the performance part played by the performer is searched. As a result, a search is made as to how many bars of the selected performance part the performance data starts. In other words, the number of bars from the beginning of the selected performance part is searched.
[0025]
Next, in step S2, the searched bar position (position where performance data is present) is compared with the current performance position. As a result of the comparison, if the current performance position has not yet reached the searched bar position, the process proceeds to step S3. On the other hand, if the current performance position has reached the searched bar position, the process proceeds to step S4. In step S2, the process also proceeds to step S3 when the current performance position is in the ending section (four bars including the last performance data). At the first time point, only automatic accompaniment is performed from the 1st bar to the 3rd bar, and the performance data is after the 4th bar, so here the process proceeds to step S3 first.
[0026]
In step S3, it is determined whether or not the current performance position is in the ending portion. Since the current performance position is at the first measure at the first time, the process proceeds to step S5. In step S <b> 5, the first display screen is displayed on the display unit 17.
[0027]
FIG. 3 is a diagram showing a first display screen that is displayed when the performance position is at the first or second measure.
[0028]
In the screen shown in FIG. 3, the display of the musical scores from the third bar to the sixth bar is displayed with the display of the musical scores of the first bar and the second bar being skipped. A ball mark 17a (corresponding to a mark referred to in the present invention) to be described later is displayed on the score of the third measure. In this embodiment, when displaying the score, the rest of the 4th to 6th bars where the player starts playing is displayed rather than displaying rests from the 1st bar to the 3rd bar where only automatic accompaniment is performed. A display mode is adopted in which the display is made in advance and the player waits until the player comes to that portion. As described above, in the present embodiment, in the intro section where the automatic accompaniment is performed for three bars before the performance by the player is started, the musical score played by the player is represented by two bars out of the three bars. Since the display is skipped and displayed on the display unit 17, the player can easily know the timing of the first performance, compared to the conventional technique of displaying only rests, and the operability of performance Will increase.
[0029]
Returning to FIG. 2 again, the description will be continued. The process proceeds from step S5 to step S7. In step S7, since the current performance position (here, the beginning of the first measure) is at a position outside the displayed score, the ball mark 17a is displayed so as to bounce up and down in FIG. By doing so, the performer can recognize that the current performance position is at the first measure or the second measure. Next, the process proceeds to step S8, the automatic accompaniment is performed, and the process proceeds to step S9. In step S9, it is determined whether or not the stop switch of the operator group 15 has been pressed or whether or not the performance has been completed. When the stop switch of the operator group 15 is pressed or when it is determined that all the performances are finished, the process proceeds to step S10, where the automatic performance is stopped and this routine is finished. On the other hand, when it is determined that the stop switch of the operator group 15 is not pressed and it is determined that the performance is not yet finished, this routine is exited, and the timer routine started by the tick shown in FIG. Repeat each step described above. In this way, the screen shown in FIG. 3 is displayed until the automatic accompaniment up to the second bar is completed, and the ball mark 17a continues to bounce up and down in FIG.
[0030]
The automatic accompaniment for the second measure ends, and the current performance position moves to the third measure. Then, in step S2, it is determined that the current performance position is within two bars, that is, the third bar with respect to the searched bar position (position where the performance data is present), and the process proceeds to step S4. In step S4, the second display screen is displayed on the display unit 17, and the process proceeds to step S7.
[0031]
FIG. 4 is a diagram showing a second display screen displayed when the performance position is at the third measure.
[0032]
Compared with the screen shown in FIG. 3, the screen shown in FIG. 4 is displayed in step S7 so that the ball mark 17a moves while bouncing from the left to the right in FIG. 4 as the score progresses. . The performer can more easily know the start timing of the performance by looking at the ball mark 17a. In the performance after the fourth measure, the performance can be easily performed by performing the performance in accordance with the progress of the ball mark 17a. Thereafter, the four bars are sequentially displayed on the display unit 17 so as to turn the page, and the ball mark 17a is also bounced from left to right.
[0033]
Eventually, the current performance position moves to the ending section. Then, in step S2, it is determined that the current performance position is in the ending part, and the process proceeds to step S3. In step S3, since the current performance position is in the ending part, the process proceeds to step S6, and a third display screen is displayed on the display part 17 in step S6.
[0034]
FIG. 5 is a diagram showing a third display screen displayed when the performance position is in the ending section.
[0035]
On the screen shown in FIG. 5, the last four bars, ie, bars 51 to 54, are displayed. From the 51st bar to the first half of the 53rd bar, as described above, the ball mark 17a is displayed so as to move while bouncing from the left to the right in FIG. Performed by performers. The performance is completed in the first half of the 53rd bar, and the ball mark 17a is displayed so as to bounce up and down in FIG. Only the automatic accompaniment is performed after the 54th bar, but the ball mark 17a continues to be displayed so as to bounce up and down in FIG. 5 until the automatic accompaniment ends.
[0036]
In the present embodiment, when the current performance position is indicated, the ball mark 17a is displayed so as to move while bouncing from left to right as the score progresses, and the current performance position is displayed. In the above description, the ball mark 17a is displayed so as to bounce up and down when it is off the score. However, the present invention is not limited to this, and the present invention is not limited to this. If a mark indicating the position is displayed and the current performance position is out of the displayed musical score, a mark having a different aspect may be displayed.
[0037]
Further, in the present embodiment, the example in which the score played by the performer is skipped in units of measures and displayed on the display unit is described, but the present invention is not limited to this, and the present invention skips in units of beats. May be displayed on the display means.
