DETAILED DESCRIPTION OF THE INVENTION
【Example】
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[0015]
FIG. 1 is a block diagram showing a schematic configuration of a musical amusement system according to an embodiment of the present invention.
[0016]
In the figure, the musical amusement system of the present embodiment includes a keyboard 1 for inputting pitch information, a panel operator 2 for inputting various information, a CPU 3 for controlling the entire system, and the CPU 3 ROM 4 for storing a control program executed by the computer, image information, etc .; RAM 5 for temporarily storing performance data during performance, calculation results executed by CPU 3, and the like; An external storage device 6 such as a cartridge, a display 7 for displaying performance information and various information, and a MIDI interface for inputting an external MIDI (Musical Instrument Digital Interface) signal or outputting it as a MIDI signal. (I / F) 8 and a sound source 9 for converting various musical sounds such as pitch information inputted from the keyboard 1 into musical sound signals, Converting a tone signal from the tone generator 9 to the acoustic, for example, it is constituted by a sound system 10 such as a speaker. The components 2 to 9 are connected to each other via an address / data bus 11, and a sound system 10 is connected to the sound source 9.
[0017]
FIG. 2 is a diagram for explaining the outline of the operation performed by the musical amusement system of the present embodiment. In the figure, (a) shows a normal score, (b) shows a score obtained by rotating the score of (a) by 90 ° in the clockwise direction, and (c) shows the score of (b) along a straight line L1. The score is folded around the center. The musical amusement system of this embodiment operates based on the score (c). In other words, according to the progression (tempo) of the song, the score (c) (c) is scrolled in the scroll direction in the figure, and the player corresponds to the note when each note of the score reaches a predetermined position. Press the keyboard 1 to play the song.
[0018]
Although the musical amusement system of this embodiment can be operated based on the score of (b), it is difficult to take the timing when the performer presses the keyboard 1 because the scroll direction is the vertical upward direction. Therefore, in this embodiment, the operation is performed based on the score (c).
[0019]
FIG. 3 is a diagram showing an example of a display screen that is actually displayed on the display 7 of the musical amusement system of the present embodiment.
[0020]
As shown in the figure, the display 7 displays each note of FIG. 2C in the shape of an apple, and also displays a keyboard so that the player can know which key to play. That is, each note in FIG. 2C is characterized and expanded in the horizontal direction, and each note is arranged at a position vertically above the key to be played by the performer.
[0021]
The applet notes are animated and scrolled from top to bottom on the screen. When the player presses the keyboard 1 to be played at the timing when the apple reaches the “current performance position” line indicated by the straight line L2, the arrow is fired and pierced by the apple. Disappear from the screen. When the apple disappears, the score is added, but when the player removes the timing to play, the arrow does not pierce the apple, the apple does not disappear, and scrolls to the end of the display screen. Similarly, when the key being pressed is released at the expected timing, a score is added.
[0022]
Since this processing is performed by the CPU 3 as will be described later, only when the keyboard 1 is played at the original timing of the song, that is, when the keyboard 3 is accurately played in the minimum time that can be processed by the CPU 3, the arrow is inserted into the apple. Even advanced players will not have an arrow in the apple. For this reason, the key press timing range is set to the sound generation permission range a1, the key release timing range is set to the mute permission range a2, and a certain margin is given to the timing of playing the keyboard 1. Therefore, when the ranges a1 and a2 are approaching the straight line L2, the performer only has to press the corresponding keyboard 1.
[0023]
In addition, when an arrow is stuck in an apple, the sound of the note may be sounded or may not be sounded. Further, whether or not to play a sound may be switched according to the level of the performer. If no sound is played, a song unrelated to the song to be played may be played as BGM. For example, BGM may be rock music when animation scrolling is performed based on a musical score of a classical piano song. However, it is better to match the tempo with the music scrolling animation. This is because the scrolling speed changes depending on the tempo, and the difficulty of playing as a shooting game changes, so it is preferable to change the BGM according to the tempo.
[0024]
Furthermore, in this embodiment, since the note length is unknown because the note is transformed into an apple, the color of the apple, for example, varies depending on the length so that the player can understand the length. do it.
[0025]
In this embodiment, the character is an apple. However, the present invention is not limited to this. For example, it may be an airplane or a bird. In this case, the character may be shot down with a machine gun or a rifle.
[0026]
A control process executed by the musical amusement system configured as described above will be described below with reference to FIGS.
[0027]
FIG. 4 is a flowchart showing the procedure of the main routine executed by the CPU 3 of the musical amusement system of this embodiment.
[0028]
In the figure, first, initial settings such as clearing the RAM 5 and clearing various ports are performed (step S1).
[0029]
Next, note information for a screen display is read from the performance data storage area secured in the RAM 5, and if the note information is included in the read note information, a sound generation permission range and a mute permission range are set for each note. It is determined and stored in a predetermined area of the RAM 5 (step S2), and a note is displayed on the display 7 in the shape of the apple (step S3). Here, the note information stored in the performance data storage area includes, for example, event data indicating the pitch and the type of the note, and duration data indicating the time interval between the event data. Stores end data indicating the end of the performance data.
[0030]
6A and 6B are diagrams showing an example of a screen displayed on the display 7, wherein FIG. 6A shows a screen before starting the performance of the song, and FIG. 6B shows a screen when the song is being played. Is shown. In the figures, numbers indicate the position of data in the performance data storage area, and in each figure, the upper numbers (“1000”, “1395”) indicate the upper limit position of the note information for the screen display, and the lower numbers (“0”, “395”) indicates the lower limit position. The straight line L2 is the “current performance position” described with reference to FIG. Hereinafter, with reference to FIG. 6, the processing of each step S2, S3 will be described in detail.
[0031]
When the range “30” is taken as the margin range (this range is preferably changed according to the type of note), for example, the sound generation permission range a1 is obtained from the event data and the duration data read out in step S2. The range 390 to 420 is determined, the mute permission range a2 is determined to be 590 to 620, the pitch is determined to be “C6”, and each of these pieces of information is stored in a predetermined area secured in the RAM 5. The Based on these pieces of information, the screen (a) is displayed on the display 7.
[0032]
Returning to FIG. 4, it is determined whether or not an instruction to start the performance of the music has been given (step S4). Here, the instruction to start the performance of the music may be performed, for example, by pressing a start switch (not shown) of the panel operator 2.
[0033]
If it is determined in step S4 that a start instruction is given, the process proceeds to step S5. On the other hand, if a start instruction is not given, the process waits until a start instruction is issued.
[0034]
In step S5, the timer interrupt is permitted so that the timer interrupt process of FIG. 5 described later is executed, and in step S6, it is determined whether or not there has been a key pressing event that occurs when the player presses the keyboard 1. To do.
[0035]
If it is determined in step S6 that there is a key pressing event, it is determined whether or not the timing of occurrence of the key pressing event falls within the sound generation permission range determined in step S2 and the pitches match (step S6). S7). This determination is made based on the sound generation permission range and pitch stored in the RAM 5 in step S2.
[0036]
If the answer is “YES” in the determination of step S7, the key press event is sounded (step S8), and the arrow is stabbed into the corresponding apple as described above, and the score of the apple stabbed with the arrow is obtained. It is calculated and added to the score so far and displayed (step S9).
[0037]
On the other hand, if there is no key depression event in the determination in step S6, steps S7 to S9 are skipped and the process proceeds to step S10. If the answer is “NO” in the determination in step S7, steps S8 to S9 are skipped. Proceed to S10.
[0038]
In step S10, it is determined whether or not there is a key release event that occurs when the performer releases the keyboard 1. If there is a key release event, the key release event is generated in the same manner as in step S7. The timing is determined in step S2, and it is determined whether or not it falls within the stored mute permission range and the pitches match (step S11).
[0039]
If the answer is “YES” in the determination in step S11, the key release event is silenced (step S12), and the score is calculated and added to the previous score in the same manner as in step S9. Displayed (step S13).
[0040]
On the other hand, if there is no key release event in the determination in step S10, steps S11 to S13 are skipped and the process proceeds to step S14. If the answer is “NO” in the determination in step S11, steps S12 and S13 are skipped. Proceed to S14.
[0041]
In step S14, the sound that is sounding past the mute range is muted, and in step S15, it is determined whether or not an instruction to stop the performance of the song has been given. Here, the stop instruction may be given by the player pressing a stop switch (not shown) of the panel setting operator 2.
[0042]
If it is determined in step S15 that a stop instruction is not issued, the process returns to step S6 and the above-described processing is repeated. On the other hand, if a stop instruction is issued, an end process is performed (step S16), and then the process returns to step S2. The above process is repeated.
[0043]
FIG. 5 is a flowchart showing the procedure of the timer interrupt process. This interrupt process is performed once every time according to the length of a predetermined note, for example. That is, the interrupt timing is changed according to the tempo. The interrupt is not limited to this, and may be generated at a timing every predetermined time (for example, 10 msec).
[0044]
In the figure, first, the current position is incremented (step S21). Here, the current position refers to the position indicated by the straight line L2 in FIG. 6, and in step S21, this position is incremented by "1".
[0045]
Next, the reading position is incremented (step S22). Here, the read position refers to the upper limit position of the note information for the screen display described with reference to FIG. 6, and in step S22, this position is incremented by “1”.
[0046]
Based on the position incremented in steps S21 and S22, the screen display of the display 7 is rewritten, and the scroll process for performing the above-described animation scrolling is performed (step S23), and the read duration data secured in the predetermined area of the RAM 5 is read. Is subtracted by "1" (step S24).
[0047]
Next, it is determined whether or not the duration time TIME is “0” (step S25). When the duration time TIME ≠ 0, the interruption process is terminated. On the other hand, when the duration time TIME = 0, note information is obtained. Read (step S26).
[0048]
Then, it is determined whether or not the read note information is a “note (that is, the event data described above)” (step S27). If it is a “note”, it is displayed as an apple on the display 7 ( Step S28), the sound generation permission range and the mute permission range are determined on the basis of the read position and the note type, and stored in a predetermined area of the RAM 5 (Step S29), as in Step S2 of FIG. After proceeding by 1 ″ (step S30), the process returns to step S26 to repeat reading of note information.
[0049]
On the other hand, if it is determined in step S27 that the read note information is not “note”, it is determined whether or not the information is “duration data” (step S31). After the time TIME is stored (step S32), the timer interrupt process is terminated.
[0050]
On the other hand, if it is determined in step S31 that the read note information is not duration data, it is determined whether or not the data is “end data” (step S33).
[0051]
If it is determined in step S33 that the read data is not end data, the interrupt process is immediately terminated. On the other hand, if the read data is performance data, the end process is performed (step S34), and then the interrupt process is performed. finish.
[0052]
As described above, in this embodiment, the note information is read out, the animation scroll is performed, and when the character corresponding to the note comes within the sound generation permission range, when the key 1 is pressed, the character is shot down and the score is obtained. When the key is released and the key is released when the key is released, the score is added and the music is muted. Even beginners who cannot read can easily and enjoy playing electronic musical instruments. In addition, since the keyboard is displayed on the display 7 and the character is scrolled at the position of the key to be pressed, the player knows which keyboard should be played sensuously. Further, when the music to be played is difficult, it becomes difficult as a shooting game, so that the user can be expanded not only to users interested in electronic musical instruments but also to game enthusiasts.
[0053]
In this embodiment, the electronic keyboard musical instrument is used as the electronic musical instrument. However, the present invention is not limited to this.
[0054]
In this embodiment, as a musical amusement system, as shown in FIG. 1, it is configured as an integrated type including all the components for carrying out the present invention. However, the present invention is not limited to this, and the components are configured separately. May be. For example, as shown in FIG. 7, an electronic musical instrument 21 that outputs a MIDI signal in accordance with a performance song and the output MIDI signal are input, and according to the processing described in FIGS. 4 and 5, as shown in FIG. A personal computer 22 for displaying on a display and outputting a MIDI signal for instructing sound generation / mute; a sound source 23 and a sound system 24 for inputting the output MIDI signal to actually generate / mute a musical sound; Thus, a musical amusement system may be configured.
[0055]
Furthermore, in this embodiment, as shown in FIG. 2 (c), the screen is scrolled from top to bottom. However, the present invention is not limited to this, and as shown in FIG. The notes (characters) may be gradually approaching.
[0056]
In this embodiment, as described above with reference to FIG. 5, interrupt processing is performed at an interrupt cycle corresponding to the tempo, so if the music to be played is too difficult for the performer, the tempo is set to be slow. It is good to do. If the tempo is slowed down, the game is naturally simpler, so it is necessary to change the weight when adding the score according to the tempo. In this way, the performer can play any difficult song by slowing down the tempo. However, in a performance that is much slower than the regular tempo, even if you can play to the end, you cannot enjoy the “feeling of playing”. Good. And as you play more and more, if you raise the tempo and start the sound and mute when it reaches the regular tempo, it should be able to play to some extent at that level, You can get the feeling that you are playing. Further, in the case where the musical piece has a performance of another musical instrument, for example, a piano concerto or the like, the presence of the orchestra is improved together with the sound generation / silence processing, and the sense of reality is further improved.
[0057]
Further, levels may be provided in the sound generation permission range and the mute permission range, respectively, and more points may be added when the event is closer to the regular timing.
[0058]
FIG. 9 is a flowchart showing the procedure of control processing executed by the musical amusement system according to the present embodiment when a function for changing the score according to the tempo is added.
[0059]
In the figure, first, a difficulty level or a tempo is selected according to an instruction from an operator or automatically (step S41). Here, “difficulty or tempo” means that the difficulty and tempo have the same relationship as usual, that is, the higher the difficulty, the faster the tempo, and the lower the difficulty, the slower the tempo. Therefore, this is to indicate that the tempo of the song may be changed by designating the difficulty level, or the tempo of the song may be changed directly. The “difficulty level” corresponds to a “surface” or “stage” of a game or the like, and the tempo, the sound generation permission range, and the mute permission range change depending on the difficulty level.
[0060]
Next, the performance of the musical composition is started (step S42), and any one of sound generation control, BGM reproduction or accompaniment reproduction is selected according to the difficulty (tempo) (step S43), and the difficulty (tempo) is selected. After the score is added in accordance with (Step S44), the performance of the musical composition is finished (Step S45). Here, the processing of steps S42 to S45 is specifically realized by the same processing as the processing of FIG. Note that the player may select the step S43 by manual operation.
[0061]
Next, a score judgment is performed by comparing the score obtained with the pass line and the fail line with the difficulty level (step S46), and the difficulty level (tempo) in the next stage is changed according to the judgment result. (Step S47), it is determined whether or not a predetermined score or more (Step S48).
[0062]
If it is determined in step S48 that the acquired score is equal to or higher than the predetermined score, that is, if the music can be played, the present control process is terminated. repeat. Therefore, when this control process can be completed, the tempo should be a regular tempo. In other words, as long as the performance cannot be performed at the regular tempo, the number of points to be acquired may be determined so as not to exceed the predetermined score.
[0063]
By adding this function in this way, you can practice the optimal song (or game) according to the level of difficulty, and keep the performer from getting bored when practicing continuously. it can.
[0064]
【The invention's effect】
As described above, according to the present invention, the score information is displayed in the vertical direction according to the performance data stored in the performance data storage means, and the displayed score information is displayed at a tempo corresponding to the performance data. Since it is scrolled in a predetermined direction, even a beginner who cannot read a score can easily and enjoy playing an electronic musical instrument.
[0065]
Further, when it is detected that the performance information has been input within the sound generation permission range given to the note of the scrolled musical score information, the control processing means performs a predetermined control process, so that the performer is sensual. In addition to knowing how to input performance information, it can be enjoyed as a game.
