BEST MODE FOR CARRYING OUT THE INVENTION

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a block diagram showing a schematic configuration of a musical amusement system according to one embodiment of the present invention.

In FIG. 1, a musical amusement system according to the present embodiment has a keyboard 1 for inputting pitch information.
A panel operator 2 for inputting various information; a CPU 3 for controlling the entire system; a ROM 4 for storing a control program executed by the CPU 3 and image information;
A RAM 5 for temporarily storing performance data during a performance, a calculation result executed by the CPU 3, and the like; an external storage device 6 such as a memory card or a ROM cartridge for storing a plurality of performance data; A display 7 for displaying, and an external MIDI (Musical Instrument)
A digital interface (I / F) 8 for inputting a digital interface (DIG) signal or outputting the signal as an external MIDI signal, and a sound source for converting various musical tones such as pitch information inputted from the keyboard 1 into musical tone signals. 9 and the sound source 9
And a sound system 10 such as a loudspeaker, for example, for converting a musical tone signal from the speaker to a sound. The components 2 to 9 are connected to the address / data bus 11.
And a sound system 10 is connected to the sound source 9.

FIG. 2 is a diagram for explaining the outline of the operation performed by the musical amusement system according to the present embodiment. In the figure, (a) shows a normal score, and (b)
FIG. 9A shows a score obtained by rotating the score of FIG.
(C) shows a score obtained by folding the score of (b) around the straight line L1. Then, the musical amusement system of the present embodiment operates based on the score of (c). That is, the score of (c) (that is, each note) is scrolled in the scroll direction in the figure according to the progression (tempo) of the music, and the player, when each note of the score reaches a predetermined position, corresponds to the note. Key 1 to play a song.

The musical amusement system of this embodiment can be operated on the basis of the musical score shown in FIG. 2B. However, since the scroll direction is vertically upward, the timing at which the player presses the keyboard 1 is performed. Therefore, in the present embodiment, the operation is performed based on the score of (c).

FIG. 3 is a diagram showing an example of a display screen actually displayed on the display 7 of the musical amusement system of the present embodiment.

As shown in FIG.
Each note in FIG. 2C is displayed in the shape of an apple, and a keyboard is also displayed 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 a key to be played by the player.

Then, the appled note is displayed on the screen,
The animation scrolls from top to bottom and moves. The player measures the timing at which the apple approaches the straight line of the “current playing position” indicated by the straight line L2, and presses the key 1 to be played. When the keyboard is pressed, an arrow is fired and pierces the apple. It disappears from the screen. When the apple disappears, the score is added. On the other hand, when the player loses the timing to play, the arrow does not stick to the apple, the apple does not disappear, and the arrow is scrolled to the end of the display screen. Similarly, when the key being depressed is released at an appropriate timing, the points are added.

Since this process is performed by the CPU 3 as will be described later, an arrow is stuck in the apple only when the keyboard 1 is played at the original timing of the music, that is, only when the CPU 3 accurately plays the keyboard in the minimum processing time. In this way, even advanced users will not be able to stick an arrow on an apple. For this reason, the range of the key-depression timing is set as a sound-permitted range a1,
The range of the key release timing is set as the silencing permission range a2, so that the timing of playing the keyboard 1 has some allowance. Therefore, when the ranges a1 and a2 are approaching the straight line L2, the player may press the corresponding keyboard 1.

When an apple is struck by an arrow, the sound of the note may or may not be emitted. Further, whether or not to sound a sound may be switched according to the level of the player. In the case where no sound is produced, a tune irrelevant to the tune to be played may be played as BGM. For example, when the animation scroll is performed based on the music score of a classical piano song, the BGM may be rock music. However, it is better to match the tempo with the song that is performing the animation scroll. This is because the scroll speed changes depending on the tempo, and the difficulty of playing as a shooting game changes, so it is desirable to change the BGM also according to the tempo.

Further, in this embodiment, since the note length is unknown because the note is transformed into an apple,
For example, the color of the apple may be changed according to the note length so that the player can understand the note length.

In this embodiment, the character is an apple. However, the present invention is not limited to this. For example, the character may be an airplane or a bird. In this case, the character may be shot down with a machine gun or a rifle. Good.

The control processing executed by the musical amusement system configured as described above will be described below with reference to FIGS.
This will be described with reference to FIG.

FIG. 4 is a flowchart showing a procedure of a main routine executed by the CPU 3 of the musical amusement system according to the present embodiment.

In the figure, first, initialization such as clearing of the RAM 5 and clearing of various ports is performed (step S).
1).

Next, note information for the screen display is read out from the performance data storage area secured in the RAM 5, and if the read note information includes a note, the tone generation permitted range, mute for each note, etc. Determine the permitted range, and
(Step S2), and the musical notes are displayed on the display 7 in the shape of the apple (step S2).
3). Here, the note information stored in the performance data storage area is composed of, for example, event data indicating a pitch and the type of the note, and duration data indicating a time interval between the event data. Stores end data indicating the end of the performance data.

FIGS. 6A and 6B are views showing an example of a screen displayed on the display 7, wherein FIG. 6A shows a screen before the performance of the music is started, and FIG. The screen at the time is shown. In the figures, the numbers indicate the positions of the data in the performance data storage area. In each figure, the upper numbers (“1000”, “1395”) indicate the upper limit positions of the note information for the screen display, and the lower numbers. ("0", "39
5 ″) indicates the lower limit position.
Is the "current playing position" described in FIG. Hereinafter, the processing of steps S2 and S3 will be specifically described with reference to FIG.

If a range "30" is taken as the margin range (this range is preferably changed according to the type of note), the event data and the duration data read in step S2 are used to determine, for example, a sound generation permission range. a
1 is determined to be in the range of 390 to 420, the silencing permission range a2 is determined to be in the range of 590 to 620, and the pitch is set to “C
6 "is determined, and these pieces of information are stored in a predetermined area secured in the RAM 5. Based on these pieces of information, the screen (a) is displayed on the display 7.

Returning to FIG. 4, it is determined whether or not an instruction to start playing the music has been given (step S4). Here, the instruction to start playing the music may be made by, for example, pressing a start switch (not shown) of the panel operator 2.

If it is determined in step S4 that a start instruction has been issued, the process proceeds to step S5. If no start instruction has been issued, the process waits until a start instruction is issued.

In step S5, a timer interrupt is permitted so that a timer interrupt process shown in FIG. 5 to be described later is executed. In step S6, it is determined whether or not there is a key press event generated by the player pressing the keyboard 1. Is determined.

If it is determined in step S6 that a key-press event has occurred, it is determined whether or not the key-press event occurrence timing falls within the tone generation permitted range determined in step S2 and the pitches match. (Step S
7). This determination is made based on the tone generation permitted range and the tone pitch stored in the RAM 5 in step S2.

In the determination in step S7, the answer is "YE
In the case of "S", the sound generation process of the key press event is performed (step S8), and as described above, the arrow is stabbed into the corresponding apple, and the score of the apple stabbed by the arrow is calculated.
The score is added to the previous score and displayed (step S9).

On the other hand, if there is no key press event in the determination of step S6, steps S7 to S9 are skipped and the process proceeds to step S10. If the answer is "NO" in the determination of step S7, steps S8 to S9 are skipped. Then, the process proceeds to step S10.

In step S10, it is determined whether or not there is a key release event that occurs when the performer releases the keyboard 1, and if there is a key release event, the key release event is performed in the same manner as in step S7. The occurrence timing of the event is determined in step S2, and it is determined whether or not the pitch falls within the stored silencing permission range and the pitch matches (step S11).

In the determination in step S11, the answer is "Y
In the case of “ES”, the key release event is silenced (step S12), and in the same manner as in step S9,
The score is calculated, added to the previous score and displayed (step S13).

On the other hand, if there is no key release event in the determination of step S10, steps S11 to S13 are skipped and the process proceeds to step S14, and if the answer is "NO" in the determination of step S11, steps S12 and S13
And skip to step S14.

In step S14, the sound that is sounding beyond the mute range is muted. In step S15, it is determined whether or not an instruction to stop the performance of the music 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.

If it is determined in step S15 that a stop instruction has not been issued, the flow returns to step S6 to repeat the above-described processing. On the other hand, if a stop instruction has been issued, end processing has been performed (step S16). Returning to S2, the above processing is repeated.

FIG. 5 is a flowchart showing the procedure of a timer interrupt process. This interrupt process is performed, for example, once every time corresponding to a predetermined note length. 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).

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.
At 21, this position is incremented by "1".

Next, the read position is incremented (step S22). Here, the read position refers to the upper limit position of the note information for the screen display described in FIG. 6, and in step S22, this position is incremented by "1".

Based on the position incremented in steps S21 and S22, the screen display of the display 7 is rewritten to perform the scroll processing for performing the above-described animation scroll (step S23). Then, a soft counter TIME (hereinafter, “duration time TIME”) storing the generated duration data is decremented by “1” (step S24).

Next, the duration time TIME
Is determined to be "0" (step S25), and when the duration time TIME ≠ 0, this interrupt processing is terminated. On the other hand, the duration time TIME =
When it is 0, note information is read (step S26).

Then, the read note information is
It is determined whether or not it is a "note (that is, the above-described event data)" (step S27), and if it is a "note", it is displayed as an apple on the display 7 (step S28). Similarly, based on the readout position and the note type, a sounding permitted range and a sound muting permitted range are determined and stored in a predetermined area of the RAM 5 (step S2).
9) After the read address is advanced by "1" (step S30), the process returns to step S26 to repeat reading of note information.

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). Is stored in the duration time TIME (step S32), and then the present timer interrupt processing ends.

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).

If it is determined in step S33 that the read data is not end data, the present interrupt processing is immediately terminated. On the other hand, if the read data is chlorine data, end processing is performed (step S34). The interrupt processing ends.

As described above, in the present embodiment, note information is read out, an animation scroll is performed, and when the character corresponding to the note comes within the sounding permitted range, the key 1 is pressed to drop the character. The score is added and the tone is pronounced, and when the key that has been pressed is released when the tone comes within the silencing permitted range, the score is added and the tone is muted. Thus, even beginners who cannot read music scores can easily and enjoy playing electronic musical instruments. Also,
Since the keyboard is displayed on the display 7 and the character scrolls at the position of the key to be depressed, the player can intuitively know which key to play. Furthermore, when the tune to be played is difficult, it becomes difficult as a shooting game, so that the range of users can be expanded not only to users interested in electronic musical instruments but also to game enthusiasts.

Although the present embodiment has been described using an electronic keyboard instrument as the electronic musical instrument, the present invention is not limited to this.

Further, in this embodiment, as a musical amusement system, as shown in FIG. 1, an integral type including all the components for implementing the present invention is used. However, the present invention is not limited to this. May be configured. For example, as shown in FIG. 7, an electronic musical instrument 21 that outputs a MIDI signal in accordance with a music piece to be played, and the output MIDI signal is input, and according to the processing described in FIGS. MI to display on the display and instruct sound on / off
Personal computer 22 for outputting DI signal
A sound source 23 and a sound system 24 which receive the output MIDI signal and actually generate / mute a musical tone.
May constitute a musical amusement system.

Further, in this embodiment, the screen is scrolled from the top to the bottom as shown in FIG. 2C. However, the present invention is not limited to this, and as shown in FIG. A note (character) may be gradually approached.

In the present embodiment, as described above with reference to FIG. 5, since the interrupt processing is performed at an interrupt cycle corresponding to the tempo, if the music to be played is too difficult for the player, It is good to set late. If the tempo is slowed down, the game naturally becomes easier, so it is necessary to change the weight for adding points according to the tempo. By doing so, the performer
Any difficult song can be played by slowing down the tempo. However, if the performance is much slower than the regular tempo, even if the user can play to the end, he / she cannot enjoy the “feeling of playing”. Good. Then, as you can play, gradually increase the tempo, and when the tempo reaches the regular one,
If the mute processing is performed, the player should be able to play to some extent at that level, so that he / she can obtain the feeling of "playing". In addition, in the case where the musical piece has a performance of another instrument, for example, a piano concerto or the like, the presence of the orchestra together with the sound production / silence processing further enhances the realism.

Further, a level may be provided in each of the sounding permitted range and the sound muting permitted range, and more points may be added when the event is closer to the regular timing.

FIG. 9 is a flowchart showing the procedure of a control process executed by the musical amusement system of the present embodiment when a function for changing a score or the like according to the above-mentioned tempo is added.

In the figure, first, a difficulty level or a tempo is selected by an operator's instruction or automatically (step S41). Here, the “difficulty or tempo” is defined as a relationship between the difficulty and the tempo, which are usually the same.
The tempo increases as the difficulty increases, and the tempo decreases as the difficulty decreases.Therefore, the tempo of the song may be changed by specifying the difficulty, or the tempo of the song may be directly changed. This is to indicate that it may be changed. The “difficulty level” corresponds to a “face” or a “stage” of a game or the like, and the tempo, the sounding permission range and the mute permission range change according to the difficulty level.

Next, the performance of the performance music is started (step S).
42), any one of sound control, BGM reproduction, and accompaniment reproduction is selected and performed according to the difficulty (tempo) (step S43), and a score is added according to the difficulty (tempo) (step S44). After that, the performance of the music piece ends (step S45). Here, steps S42 to S4
The processing of No. 5 is specifically realized by the same processing as the processing of FIG. The selection in step S43 may be manually performed by the player.

Next, a score judgment is made by comparing the acquired score with a pass line and a reject line of the difficulty level (step S46), and the difficulty level (tempo) in the next stage is determined according to the judgment result. Is changed (step S47),
It is determined whether or not the score is equal to or higher than a predetermined score (step S48).

If it is determined in step S48 that the obtained score is equal to or greater than the predetermined score, that is, if the music can be performed, the control process is terminated. Is repeated. Therefore, when this control processing can be completed, the tempo should be the normal tempo. Conversely, before you can play at the regular tempo,
The score to be obtained may be determined so that the score does not exceed a predetermined score.

By adding this function in this way, it is possible to practice (or play a game of) the most suitable music in accordance with the difficulty level, and to keep the player from getting tired when practicing continuously. can do.

[0064]

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 scrolled in a predetermined direction at a tempo according to the performance data, so that the score cannot be read. This has the effect that even a beginner can easily and enjoy playing an electronic musical instrument.

When it is detected that the performance information has been input within the sound-permitted range assigned to the notes of the scrolled score information, the control processing means performs predetermined control processing. Can understand how to input performance information intuitively, and can also enjoy the game.
