FIG. 3 and FIG. FIG. 3 is a flowchart showing a process performed by the game control unit 1 of
FIG. 1 when the CD player starts playing a CD and the user plays while listening to music.
[0021]
In FIG. 3, when the user inserts a CD into a CD player and starts reproduction of audio data, the
game control unit 1 performs an initialization operation (step S301). In the initialization process,
the score is first set to 10 points. Subsequently, a G file corresponding to the music file to be
reproduced is acquired from the G file storage unit 3, and a screen as shown in FIG. 4 is
displayed on the display 5.
[0022]
08-05-2019

FIG. 4 shows the screen when the user plays the drum part, and the circle shows the score of the
bass drum, the mark of the rhombus shows the score of the snare, and the mark of X shows the
score of the hi-hat. The left star indicates the current playing position, and is displayed at the
position shown in FIG. 4 at the beginning of playing.
[0023]
In the screen of FIG. 4, a score of two bars is first displayed, and the star moves in units of one
beat as the music progresses. When the music reaches the second measure, the third measure is
displayed where the score of the first measure was displayed. When the music progresses further
and the second measure is finished, the star returns to the start point (at the moment the score of
the first measure of the third measure is displayed at the moment) and the fourth measure is
where the score of the second measure was displayed Display the score of.
[0024]

When the user presses a button, the operation is transmitted from the controller 4 to the game
control unit 1 as a controller event (step S302). Subsequently, the game control unit 1 refers to
the music score data of the drum part of the G file, and selects the closest note on the time axis at
the time when the controller event occurs (the time when the user presses the button).
[0027]
The game control unit 1 calculates a time difference between the occurrence time of the
controller event and the time of the selected note, and determines whether the time difference is
within a predetermined time (step S303). When it is not within the predetermined time (step
S303: No), the score is deducted by one point (step S304).
[0028]
At this time, in order to notify the user that the point has been deducted, the game control unit 1
causes the speaker 8 to generate a deduction sound (step S305). The tone reduction sound or the
volume may be changed according to the score after the point reduction.
[0029]
When the point deduction processing is completed, the game control section 1 applies effects to
the music to be reproduced by the effect section 6 in accordance with the points after deduction
(step S306). FIG. 5 shows the correspondence between the score and the effect in the present
embodiment.
[0030]
In FIG. 5, when the score is 10 points, the effect unit 6 reproduces the music with an original
sound without applying an effect. When the score is 9 points, the effect unit 6 passes a low pass
filter with a cutoff frequency of 10 kHz. The high pass is attenuated by the low pass filter, and a
narrow band sound is reproduced.
08-05-2019

[0031]
When the score is 8 points, the effect unit 6 passes a low pass filter with a cutoff frequency of 5
kHz. Because the cut-off frequency is low, a narrower band of sound is played back than at the 9
point.
[0032]
When the score is 7 points, the effect unit 6 passes a low pass filter with a cutoff frequency of 5
kHz and a high pass filter with a cutoff frequency of 1 kHz. By adding a high-pass filter, the bass
range is attenuated, and a powerful sound is reproduced. At the same time, the sound of a
rhythm musical instrument or the like containing a large amount of low frequency components is
also attenuated.
[0033]
When the score is 6 points, in addition to the effect of the score 7, a vocal cancellation effect is
added to cut the sound localized at the center (monaural component sound). If the score is 5
points, in addition to the 6 points effect, add a medium distortion.
[0034]
If the score is 4 points, in addition to the 6 points effect, add even more distortion. When the
score is 3 points, in addition to the effect with 4 points, the volume is further reduced to about
half of the normal level.
[0035]
If the score is 2 points, in addition to the effect with 3 points, add an echo effect. If the score is 1
point, add 2 points to the effect and further reduce the volume. If the score is 0, the volume is set
to 0 and the game is over.
08-05-2019

[0036]
As described above, as the score is deducted, the effect of the effect added by the effect unit 6 is
increased, and the music has a different impression from the original music. As types of effects to
be added by the effect unit 6, in addition to those listed in FIG. 5, band limitation by a band
eliminate filter, distortion-based effects such as overdrive, and the like can be considered.
[0037]
Returning to FIG. 3, when it is within the predetermined time in the determination in step S303
(step S303: Yes), the game control unit 1 adds one point to the score (step S307). The score is 10
points at the upper limit and does not reach 11 points or more.
[0038]
When the score addition processing is completed, the game control unit 1 applies an effect to the
music to be reproduced by the effect unit 6 according to the score after addition, as in step S306
(step S308).
[0039]
When the music performance has not ended (step S309: No), the process returns to step S302
again, and repeats steps S302 to S309 each time the user presses a button.
[0040]
As described above, using the CD player of the present embodiment allows the user to enjoy not
only listening to music but also participating in the performance.
In addition, when the user plays the music to the end while the score is always 10 points, it is
possible to obtain a sense of achievement that the music has been played.
Furthermore, it is possible to enjoy the pleasure that the user participated in the performance of
08-05-2019

[0051]
The operation in the practice mode will be described in detail below.
When the user operates the mobile phone to instruct the practice mode and selects a music to
practice, the game control unit 1 acquires the G file corresponding to the music from the G file
storage unit 3. On the other hand, the music file corresponding to the music designated by the
user is not reproduced.
[0052]
The game control unit 1 displays the obtained score data of the G file on the display 5. Here, the
screen displayed on the display 5 is the same as that shown in FIG. 4 or 7. In this embodiment,
the practice of the drum part is described as an example, as in FIGS. 4 and 7.
[0053]
Thereafter, when the user instructs to start practice, the game control unit 1 outputs the music
score data including the drum part to the sound source unit 31 for G file. The G-file tone
generator 31 generates tone data from the input score data, and reproduces the tone with the
