Description

[Detailed Description of the Invention] This invention relates to a music game device useful for practicing keyboard instruments and listening training.

Generally, when practicing a keyboard instrument, it is impossible to check by yourself whether or not you have pressed the keys correctly corresponding to the notes on the staff, and you cannot practice effectively unless you have a teacher watching.

Also, when conducting listening training, the teacher had to judge whether a problem sound was occurring or not.

Therefore, as seen in Japanese Patent Application Laid-open No. 56-17379, for example, musical tones of each pitch are randomly generated as problem tones, and then the pitches are compared with the pitches specified by the keys pressed on the keyboard. It determines whether there is a match or a mismatch, and notifies the result of the determination (correct/incorrect). Furthermore, it is possible to change the difficulty level of the randomly generated musical tones, and the number of correct answers is displayed every time a predetermined number of determinations are made. A pitch education device has been proposed that can also perform the following tasks.

By using such a device, even a single person can practice being a keyboard player and training his/her listening skills.
As the user becomes more skilled, even if the difficulty level of the generated musical tones is increased, he or she will eventually get most of the answers correct, so there is no longer any goal to strive for, and the user may become bored.

This idea was made in view of these conventional problems, and the purpose is to provide a music game device that allows even experienced players to further improve keyboard operation and listening sensation without getting bored. do.

Therefore, the music game device based on this invention is
A pitch data generating means for randomly generating pitch data; a means for displaying a note corresponding to the pitch data generated by the pitch data generating means or producing a musical tone to present a problem note; a keyboard device that generates pitch data corresponding to a key that is played;
Comparing and determining means for comparing the pitch data generated by the pitch data generating means and the pitch data generated by the keyboard device to determine whether the two pitch data match or do not match;
A timer for measuring the time from when the pitch data generating means generates the pitch data until a matching output is obtained from the comparing and determining means, and based on the timekeeping output of this timekeeping means, the smaller the timekeeping output, the higher the score. The present invention is equipped with a score calculation means that calculates a score as follows, and a score display means that displays the score calculated by the score calculation means.

According to the music game device constructed in this way, problem tones of random pitches are displayed or pronounced as musical notes.
When the user presses a key on the keyboard that they think corresponds to the pitch of the problem sound, it is determined whether or not it matches the pitch of the problem sound, and if it matches, the problem sound is presented and a match is made. A score (the shorter the time, the higher the score) is displayed depending on the time it takes for the question sound to be determined (depending on the time from when the question sound is presented until the user presses the key).

Therefore, no matter how skilled you are, the time it takes to press a key will never become zero, so the goal is to further shorten this time and increase your score, so you can increase your skill level while enjoying the game without getting bored. I can do it.

Further, the pitch data generation means has means for changing the range of the generated pitch data based on the calculation result of the score calculation means, and in the case of a high score, the pitch data generation range is expanded. Then, the questions will automatically follow the user's level, making the game even more interesting.

Further, since the range control means can expand the range of the pitch data randomly generated by the pitch data generation means, it is easy to change the level of the game according to the player's ability.

Hereinafter, embodiments of this invention will be described with reference to the accompanying drawings.

FIG. 1 shows the external appearance of a portable keyboard electronic musical instrument incorporating a music game device according to this invention. Like a normal keyboard electronic musical instrument of this kind, it has a keyboard 1, a speaker 2, a power switch 3, a volume/tempo switch, It is equipped with adjustment knobs 4 such as , select keys 5 for tone, rhythm, etc., and can perform music using a normal keyboard.

This electronic keyboard instrument further includes a display 6 including a staff notation display means for displaying the pitch on the staff, a game start switch 7 for starting the game, and as a problem, a display 6 including a staff notation display means for displaying the pitch on the staff. A shift mode switch 8 for selecting a shift mode is provided to select whether or not to move at regular intervals.

As shown in an enlarged view in FIG. 2, the display 6 includes a staff notation display section 60 in which four sets of note patterns 61 to 64 for displaying pitches on the staff are arranged at intervals in the left-right direction; It consists of a score display section 65 that displays the score, and a piece-possession display section 66 consisting of three quarter note patterns that displays the number of pieces that you have.

Note patterns 61 for each group on the staff display section 60
64 is composed of a whole note-shaped liquid crystal pattern or a light emitting diode (LED), each indicating pitches of 11 tones from "do" on the lower first line to "hua" on the fifth line. # and ♭ symbols indicating semitones and other display patterns are also liquid crystal patterns or
Composed of LEDs.

Next, the configuration of the music game device incorporated into this keyboard electronic musical instrument will be explained with reference to FIG. Note that parts in FIG. 3 that correspond to those in FIG. 1 are given the same reference numerals.

In FIG. 3, reference numeral 10 denotes pitch data generating means for randomly generating pitch data, for example,
A plurality of pitch data corresponding to each note in the musical range obtained by displaying on the staff notation display section 60 in FIG.
A random number generator 11 consisting of, for example, a pseudo-random pulse generator that generates random numbers as a random number, and a latch circuit 1 that latches the numerical data (random numbers).
It consists of 2.

When the self-recovery type game start switch 7 is turned on, the pitch data generating means 10 stops operating the random number generator 11 that has been operating up to now, and generates data when the latch circuit 12 stops operating. is latched and output as pitch data RD.
Thereafter, every time the next data generation signal _S1 is input, the latch circuit 12 latches new random number data and updates the pitch data RD. Further, this pitch data generating means 10 changes the range of the generated pitch data in accordance with a signal _S2 from a detector 39 that detects a score calculation result by a score calculator 31 which is a score calculation means to be described later. The sound range of the pitch data generated when the signal _S2 becomes "1" is expanded.

13 is a keyboard device that generates pitch data corresponding to a pressed key;
and a pitch data generation circuit 14 that generates pitch data KD based on numerical data corresponding to each key.

The pitch data RD generated by the pitch data generating means 10 is input to the music signal generator 18 through the gate circuit 15 and the OR circuit 17, which are controlled to be in a normally open state, and is converted into a corresponding music signal. and the sound is output from the speaker 19.

At the same time, the pitch data RD is set to selector 20.
(When the shift mode switch 8, which will be described later, is open, input A, that is, selects pitch data RD and shift data "0") is input to the staff notation display section 60 of the display 6 shown in FIG. , the notes corresponding to this pitch data RD are displayed, for example, by the leftmost note pattern 61.

That is, these musical tone signal generator 18 and speaker 19, and the staff display section 60 of the display 6
is a means for presenting a problem sound corresponding to the pitch data generated by the pitch data generating means 10, and in this embodiment, the problem sound is presented both as a note display and as a musical sound pronunciation. However, only one of these may be performed.

When the player sees this and presses any key on the keyboard 1, pitch data KD corresponding to the pressed key is generated from the keyboard device 13.

As a result, the output of the OR circuit 21 that ORs each bit of the pitch data KD becomes "1", which enables the digital comparator 22 which is the comparison/determination means, and also changes the output of the NOR circuit 23 to "0". ”, and the output of the AND circuit 24 is set to “1”.

Therefore, the gate circuit 15 is closed, the gate circuit 16 is opened, and the pitch data from the keyboard device 13 is
KD is inputted to a musical tone signal generator 18 through a gate circuit 16 and an OR circuit 17, converted into a corresponding musical tone signal, and produced from a speaker 19.

On the other hand, the digital comparator 22 compares the pitch data RD from the random pitch data generating means 10 and the pitch data KD from the keyboard device 13, determines whether the two pitch data match or do not match, and If so, the output signal _S3 is set to "1".

When this signal _S3 is input to the timer 25, the output signal _S4 becomes "1" after a preset time delay, and the correct sound data generator 26 notifies the player that the answer is correct. Generate the correct sound data SD.

The reason why the timer 25 is provided here is to limit the duration of the key depression sound when the keys on the keyboard 1 are pressed for a long time, and to stop the key depression sound before the correct sound is generated.

Note that the correct sound data generator 26 can be configured by a read-on memory (ROM) storing correct sound data and a data reading circuit thereof.

The correct sound data SD is inputted to the musical tone signal generator 18 through the OR circuit 17, converted into a corresponding musical tone signal, and outputted from the speaker 19.

At this time, even if the key is still being pressed, when the output signal _S4 of the timer 25 becomes "1", the flip-flop circuit 27 is set and its Q output becomes "1", so it is inverted and input. The output of the AND circuit 24 becomes “0”, and the gate circuit 1
6 is closed, pitch data from the keyboard device 13 is no longer produced.

Then, when the correct sound data generator 26 finishes generating the correct sound data SD, the end signal _S5 is set to "1", so that the pitch data KD from the keyboard device 13 disappears and the output of the OR circuit 21 is When it becomes "0" and the output of the inverter 28 becomes "1", the output of the AND circuit 29 becomes "1", which resets the flip-flop circuit 27 and makes its Q output "0". Return to the initial state in which the open gate circuit 16 is closed.

By the way, when the output signal _S4 of the timer 25 becomes "1", the aforementioned next data generation signal _S1 , which is the output of the OR circuit 30, becomes "1", so that the random pitch data generation means 10 is newly activated. Ratana pitch data
RD will now occur.

Therefore, the musical note corresponding to the pitch data RD is displayed on the staff notation display section 60, and when the gate circuit 15 is closed after the correct tone is generated, a musical tone corresponding to the new pitch data is sounded. .

When the pitch data RD and KD do not match and the output signal _S3 of the digital comparator 22 remains "0",
The game may be ended as it is, but in this embodiment, the following various functions are added to make the game more interesting.

First, a score calculator 31 is provided to display a score according to the number of correct answers, and the output signal _S3 of the digital comparator 22 becomes "1", and the output signal _S4 of the timer 25 becomes "1". The score is added for each time, and the score is displayed on a 4-digit score display section 65 using a 7-segment numeric display element on the display 6 in FIG.

In this embodiment, when the shift mode switch 8 is closed, count data CD of a note shift counter 32 (described later) is input to the score calculator 31, and even if the answer is correct, the count data CD The number of points to be added is reduced according to the number of points (increased).

Next, instead of ending the game due to one incorrect answer, the game can be continued until a predetermined period of time (maximum 1 minute in this example) has elapsed. I am trying to display it as a number.

The counter 33 is a counter that controls the display of the piece display section 66, and is set to "1" by a signal _S6 from the timer circuit 34 that becomes "1" every 20 seconds or when the counter 32 counts over during the shift mode described later. This counter inputs the output signal _S7 of the AND circuit 35 to the clock input terminal via the OR circuit 36 and counts from 0 to 3.

And the count data of this counter 33
Every time ND counts up, the number of pieces displayed in the piece display section 66
When the count data ND reaches "3", there are no more pieces left, the count over signal _S8 becomes "1", and the output of the OR circuit 37 becomes "1". The pitch data generating means 10, the score calculator 31, each counter, timer, etc. are all reset, and the game is ended.

Further, in this embodiment, when the shift mode switch 8 is turned on, the notes displayed on the staff display section 60 are shifted in accordance with the passage of time.

That is, when the shift mode switch 8 is closed, the counter 32 is reset and becomes operational, counts the slow clock pulses generated by the oscillator 38, and when it counts up to "4", sets the count over signal _S9 to "1". '', it resets itself, and when the output _S4 of the timer 25 becomes ``1'', it is also reset and the count data CD becomes ``0''.

When the shift mode switch 8 is on, the selector 20 selects the B input, that is, the pitch data RD and the count data CD as shift data, and outputs them to the staff display section 60.

As a result, the staff display section 60 displays pitch data.
When the count data CD is "0", the note corresponding to RD is the leftmost note pattern 61 in Figure 2.
and the count data CD is “1”, “2”,
As the count increases to "3", the musical note patterns 62, 63, and 64 are sequentially moved and displayed, and when the count data CD reaches "4", the musical notes are no longer displayed. In this way, the player is informed of the passage of time and prompted to press a key on the keyboard.

Further, the count data CD is input to the score calculator 31 so that the smaller the count data CD when the output signal _S4 arrives, the larger the score is output. This is because if the count data CD is small, it means that the matching key was pressed early.

Then, when the next data generation signal S1 becomes " ₁ " by the countover signal _S9 from the counter 32 and new random pitch data is generated, the note corresponding to the pitch data is again generated. is displayed on the note pattern 61.

Furthermore, when the score calculated by the score calculator 31 exceeds a preset score, the detector 39 sets the output signal _S2 to "1", thereby
The pitch data generation means 10 expands the pitch data generation range to make the problem more difficult, and the oscillator 38
As the oscillation frequency increases, the scoring criteria become stricter.

As explained above, in the music game device according to this invention, problem tones of random pitches are displayed or pronounced as musical notes, so that the user can respond to the pitch of the problem tones on the keyboard. When you press a key that you think will match the pitch of the problem sound, it is determined whether or not it matches the pitch of the problem sound, and if it matches, the time from the presentation of the problem sound until the match is determined, that is, the problem sound is presented. The shorter the time it takes for the user to press a matching key, the higher the score will be displayed, allowing the user to practice quickly determining the pitch of the presented problem sound and pressing the keys.

Therefore, one person can effectively practice key operations on a keyboard instrument and practice listening.

Moreover, no matter how skilled you are, the time it takes to press a key will never reach zero, so the goal is to further shorten this time and increase your score, so you can enjoy the game without getting bored and increase your skill level. .

Also, if you change the range of the next problem sound depending on the score, and expand the range for high scores, the questions will automatically follow the user's level. , it can increase your interest even more.
