Description

[Detailed Description of the Invention] [Field of Use of Rakudo] The present invention relates to a music game device suitable for use in music education, and particularly to a technique for notifying the level achieved in a game according to the score.

[Summary of the Invention] This invention allows a gamer to easily auditorily determine the game reach 1/bell according to the score by changing the characteristics such as the timbre and effect of a musical tone having a pitch as a problem depending on the score. It is designed so that it can be recognized.

[Prior Art] Conventionally, while musical tones having a pitch as a problem are generated one by one, the game player is asked to press a key corresponding to the problem pitch on a keyboard, and the problem pitch and key press sound are generated. A music game device is known in which a match with a high score is detected as a score and the score is displayed on a score display (for example,
(See Publication No. 17480).

[Problems to be Solved by the Invention] According to the conventional device described above, in order to recognize the level reached in the game, it is necessary to read the score by looking at the score display, and during the game, it is necessary to shift the eyes from the keyboard to the score display. Therefore, there was an inconvenience in that the smooth progress of the game was hindered. Furthermore, since the score display is provided on the panel surface near the keyboard, the panel configuration inevitably becomes complicated.

By the way, in the above-mentioned conventional device, when the score reaches a predetermined value (for example, 50 points), the speed of change of the problem pitch is increased in order to increase the difficulty of the game. It can be inferred that the attained level has increased because the time interval between musical tones has become shorter. However, changes in the time intervals between musical tones cannot be known unless one listens to a series of musical tones, and it is difficult for beginners to recognize the level reached through hearing.

An object of the present invention is to enable even beginners to easily recognize the attainment level based on the score audibly.

[Means for Solving the Problems] A music game device according to the present invention includes pitch data generating means, musical tone generating means, pitch specifying means, comparison means, and musical tone characteristic specifying means.

The pitch data generating means sequentially (preferably randomly) generates pitch data as a problem.

The musical sound generating means generates a musical sound signal having a pitch corresponding to the pitch data and having musical sound characteristics such as specified timbre and effects each time pitch data is generated from the pitch data generating means. It is something to do.

The pitch specifying means is composed of a keyboard or the like capable of specifying an arbitrary pitch, and is adapted to send out specified pitch data representing the specified pitch.

The comparing means compares the pitch data from the pitch data generating means and the specified pitch data from the pitch specifying means, and sends out a matching output every time the two match.

The musical tone characteristic specifying means counts the matching outputs from the comparing means and specifies the musical tone characteristic of the musical tone signal according to the score corresponding to the counted value.

In the above-described configuration, the musical tone generating means generates a matching sound signal having specified sound characteristics such as tone color and effect each time a matching output is sent from the comparing means, and the musical sound characteristic specifying means The sound characteristics of the matching sound signal may be specified according to the score corresponding to the numerical value.

[Function] According to the configuration of the present invention, musical sound characteristics such as the timbre and effects of the musical sound signal are specified and controlled according to the score, so the game player can change the timbre, effects, etc. even without a score display. The level reached can be easily recognized aurally.

In addition, as mentioned above, if the sound characteristics such as timbre and effect are specified and controlled according to the score of the matching sound signal,
It becomes easier to recognize the level of achievement.

[Embodiment] FIG. 1 shows a circuit configuration of an electronic musical instrument equipped with a music game device according to an embodiment of the present invention, and this electronic musical instrument selectively operates in a normal performance mode and a game mode. be able to.

Normal performance mode operation is game switch (SW) 10.
This is done when the switch is turned off as shown in the figure. That is, when the game switch 10 is in the off state IE, the output of the inverter 12 = "1" is supplied to the gate circuit 14 as the enable signal EN, so the gate circuit 14 becomes conductive. In such a state, When a key is pressed on the keyboard 16, the key press detection circuit generates pitch data KPD corresponding to the pressed key, and this pitch data KP
D is supplied to the musical tone forming circuit 20 via the gate circuit 14. The musical tone forming circuit 20 uses the supplied pitch data KP.
A musical tone signal having a pitch indicated by D is formed and sent to the speaker 22.
As a result, the speaker 22 emits a musical tone corresponding to the pressed key. Therefore, in the normal performance mode, the user can enjoy playing a desired piece of music using the keyboard 16.

The game mode operation is performed when the game switch 10 is turned on. That is, game switch 1
When 0 is turned on, the output of the inverter 12 becomes 0'' and the gate circuit 14 becomes non-conductive, while the rising differential circuit 3
0 rises and differentiates the switch-on signal from the switch 10 to generate a game-on signal GS. This game-on signal GS is supplied to the game control/performance data generation circuit 32.

The game system m/performance data generation circuit 32 includes, for example,
It is constructed as shown in FIG.

The R-S flip-flop 34 is set in response to the game-on signal GS as shown in FIG.
1 is supplied to AND gate 38. At this time, since the game state signal GMCT is 0'' as shown in FIG. 3, the output of the inverter 38 = 11111 is
6. Therefore, the AND gate 3G is
In response to the output of the flip-flop 34 becoming '1', the output becomes '1', and this output = '1' is supplied to the intro performance data generation circuit 40 as an enable signal EN.

The intro performance data generation circuit 4o includes a ROM (read only memory) that stores intro performance data, and when the enable signal EN becomes "111", it sequentially reads out the intro performance data from the ROM and outputs the performance data PFD. The musical tone forming circuit 2o forms a performance sound signal based on the supplied performance data PFD and supplies it to the speaker 22.
As shown in FIG. 3, the speaker 22 generates an intro performance sound for a certain period of time from the start of generation of the game-on signal GS. This intro performance sound is for notifying the game player that the game will be available from now on.

The end detection circuit 42 detects the end of reading the intro performance data and generates a game start signal GMST, and this game start signal GMST resets the flip-flop 34. As a result, the intro performance data generation circuit 40 enters the displeasure state.

The game start signal GMST is supplied to the R-S flip-flop 50 of FIG. Therefore, the output from the flip-flop 50 is “1”.
A game state signal GMCT consisting of " is generated as shown in FIG. 3, and the game is enabled during the period when this signal GMCT is "1".

The random data generation circuit 52 sequentially generates random data RDA for determining pitch and random data RDB for determining the direction of movement (direction of pitch change), respectively.
Random data RDA is provided as input C to register 54. The register 54 contains a game start signal GM.
Since ST is supplied as the capture command signal sc for input C via OR gate 56, register 54 is
The random data RDA at that time is taken in and held in response to the Game Star I signal GMST. The data held in the register 54 is then supplied to the selector 58 as pitch data GPD as the problem. At this time, the selector 58 is in a state of selecting the pitch data GPD as input A, so the pitch data GPD is selected by the selector 58.
The signal is supplied to the gate circuit 6o via the gate circuit 6o. At this time, the gate circuit 60 receives the game state signal GMCT="l" as the enable signal EN and is in a conductive state, so the pitch data GPD is supplied to the musical tone forming circuit 2o via the gate circuit 60.

By the way, the tone control counter 62 receives the game state signal G.
The output of the inverter B4, which receives MCT as an input, is received as a reset signal R via the OR gate 66, and the reset is canceled in response to the game state signal GMCT='"1°. Immediately after the game starts, , the count value of the counter 62 is O, and the count output indicating this count value O is supplied to the musical tone forming circuit 20 as timbre designation data TCD.

Regarding the count values O11, 2, . The tone corresponding to the count value is automatically set. Therefore, when the data held in the register 54 is supplied to the musical tone forming circuit 20 as the pitch data GPD immediately after the game starts as described above, it has the pitch indicated by the pitch data and the count value O of the counter 62. A musical tone signal having a corresponding tone color is generated by the same circuit 20, and this musical tone signal is emitted from the speaker 22 as the first problem tone.

When the first problem sound is generated, the gamer can press a key on the keyboard 16 that corresponds to the problem sound and the pitch. Pitch data KPD corresponding to the pressed key is then supplied from the key press detection circuit 18 to the comparison circuit 68 as comparison human power B. The comparison circuit 68 compares the pitch data GPD as the comparison input A and the pitch data KPD as the comparison human power B, and when the two match in pitch (A=B), generates a match output EQ. - Sporadic sound control circuit 70
supply to.

For example, the coincidence sound generation control circuit 70 has a configuration as shown in FIG.
is inputted to the counter 74 via.

The counter 74 outputs Qo according to the matching output EQ.
1°', and this output QO="1" is OR gate 76
The AND gate 78 is made conductive via the . Therefore, the clock signal φ is input to the counter 74 via the AND gate 78 and the OR gate 72, and the counter 74 starts counting the clock signal φ.

On the other hand, since the output QO="1" of the counter 74 sets the R-S flip-flop 80 via the OR gate 76, the scattered sound control signal EQT consisting of the output Q of the flip-flop 80 generates the coincidence output EQ. in sync with “°
1'. Thereafter, when a predetermined period of time has elapsed since the occurrence of the coincidence output EQ, the output Qo "Q3" of the counter 74 changes from the state of all bits "1" to the state of all bits "1.0". becomes non-conductive, and the counter 74 stops counting. On the other hand, the flip-flop 80 is reset in response to the output of the inverter 82 which receives the output of the OR gate 76 = "l°", and the coincidence sound generation control signal E is reset.
QT changes from °゛1'' to °°Opa.

The matching sound generation control signal EQT is supplied to the selector 58 in FIG.
D is supplied. Therefore, -the scattered sound data EQD is
During the predetermined period when the coincidence sound generation control signal EQT is at 1, it is supplied from the selector 58 to the musical tone forming circuit 20 via the gate circuit 60. The musical tone forming circuit 20 forms a sound signal corresponding to the supplied one-tone data EQD and sends it to the speaker 22. In this case, the sound signal is transmitted to the counter 62
Since it is formed to have a tone color corresponding to the count value O, the speaker 22 emits a matching tone with the same tone color as the first question tone. Therefore, the game player is informed that the key press was correct and matched the question pitch.

The coincidence output EQ is also supplied to a score counter 86.

The score counter 86 receives the output of the inverter 88 which receives the game state signal GMCT as a reset signal R via an OR gate 90, and is reset in response to the game state signal GMCT="1". .

Therefore, the count value of the counter 88 increases by 1 in response to the coincidence output EQ.

The coincidence output EQ is outputted via OR gate 56 to 1/register 5.
4 is also supplied as a capture command signal SC. For this reason,
New random data RDA is taken in and held in the 1/register 54. And in the same way as above,
A question sound is generated in response to the new random data RDA, and if the question tone is pressed correctly on the keyboard 1B, a matching tone is generated and the count value of the counter 86 increases by 1. After this, you can return green with a similar action.

The above is the behavior when a key is pressed correctly every time a problem sound occurs, but if a key is not pressed or a key is pressed incorrectly after the first problem sound occurs, the following behavior occurs. .

That is, the data held in the register 54 is sent to the addition/subtraction circuit 92.
is supplied to the control signal i n and sets the numerical value 1 corresponding to a semitone to
The pitch is changed by adding or subtracting according to c/de c. The control signal inc/dec is “0”.
If ゛, add (pitch rise); if ``'l°°, subtract (
This circuit is formed by a circuit including a direction determining circuit 94, a clock generator 96, a rise differentiation circuit 9, and an AND gate 100.

The traveling direction determining circuit 94 has a configuration as shown in FIG. 5, for example. 4-bit signal B forming random data RDB from random data generation circuit 52
Of O-83, BO and Bl are input to the register 102, and B2 and B3 are input to the conversion circuit 106. The register 102 receives as a load signal LD the frequency-divided output of the frequency divider 104 that divides the clock signal CLK from the clock generator 9G by 1/16, and the signals BO and B1 are output every 16 Hals of the clock signal CLK. loaded. Here, the clock signal CLK includes pulses generated at a period corresponding to a predetermined musical note (for example, a quarter note).

Conversion circuit 101 (is OR gate OG+, OG2
.

The AND gates AG, AC3 and NOR gate NOG are connected as shown in the figure, and the operation as shown in FIG. 6 is possible.

That is, in case (A) where inputs bo and bl are "00", inputs B2 and B3 are "00" to "11".
If the output DS changes randomly within the range of , the output DS will be "]" only when the inputs B2 and B3 are "11", and the forward (pitch rise) probability will be 75%. In addition, in the case of (B), (c), and (D) where the inputs bO and bl are ro IJ, "10", and "11", respectively, the forward probabilities are 50[%] and 50[%], respectively, as shown in the figure. %], 25[%]. In other words, the register 102 operates to randomly switch the advance probability every 16 pulses of the clock signal CLK.

The rising differentiation circuit 88 differentiates the rising edge of the clock signal CLK to generate an output pulse DC, and in accordance with this output pulse DC, the AND gate 100 converts the output DC of the circuit 94 at that time into a control signal i n c / de c The signal is supplied to the addition/subtraction circuit 82 as a signal. Therefore, if the output of the circuit 94 is "O", the adder/subtractor circuit 92 sends pitch data that is a semitone higher than the data held in the register 54, and if the output of the circuit 94 is 1", pitch data is sent out by 1/2". Pitch data that is a semitone lower than the data held in register 54 is sent out. Pitch data from addition/subtraction circuit 82 is then supplied to register 54 as input B.

The register 54 is adapted to receive the output pulse DC of the rising differential circuit 9 as the acquisition command signal SB for the input B, and the register 54 receives the output pulse DC from the addition/subtraction circuit 82 every time the output pulse DC is generated. The pitch data of is captured and retained. The data held in the register 54 is transferred to the selector 58 and the comparison circuit 6 as pitch data GPD.
8. As a result, a problem sound is generated from the second speaker 22 in such a way that the pitch changes by a semitone at a cycle corresponding to the clock signal CLK, and the game player presses a key to match the pitch of the generated problem sound. You can enjoy playing the sound guessing game. In this case, the pitch of the problem sound is
For example, when the advance probability is 75%, microscopically it changes randomly by semitones, but macroscopically it changes (advances) toward the higher notes, and as mentioned above. Since the advance probability is randomly changed by the action of the register 102, it is possible to enjoy a game rich in variety.

When a key is pressed on the keyboard 16 as a problem tone is generated for each pulse of the clock signal CLK as described above, each time the pressed key pitch matches the problem tone pitch, the comparator circuit 68
A coincidence output EQ is sent out from. And each matching output E
In response to Q, a single sound is generated in the same manner as described above, while new random data RDA is taken into the register 54 and held in response to each coincidence output EQ. Thereafter, based on the data held in the register 54, problem tones that change in semitone increments are generated in the same manner as described above.

Incidentally, the score counter 86 counts the coincidence output EQ and generates an output pulse FT at the timing when the counted value reaches 30. This output pulse FT resets the counter 86 via the delay circuit 108 that provides a minute delay and further via the OR gate 90, so the counter 86 starts counting the coincidence output EQ again after this.

The output pulse FT from the counter 86 is supplied to the counter 62, and the count value of the counter B2 increases by 1 in response. For example, when the count value of the counter 62 is 0, it becomes 1, and in response to this, the tone forming circuit 20 automatically sets new tones for the problem tone and the -dissonant tone. Therefore, the game player can easily recognize the level reached according to the score (30 points) from the change in tone color.

The counter 62 outputs an output pulse FT generated every 30 points.
When a predetermined maximum score (for example, 120 points) is reached, an output pulse M is sent from the counter 62.
This output pulse M is the output pulse PT from the counter 86.
is supplied to an AND gate 110 having as input. Therefore, the AND gate 110 outputs the highest score signal MX.

The R-S flip-flop 112 selects Sera! in response to the highest score signal MX.・The output Q=“1” is sent to the game control/performance data generation circuit 32 as a high score signal HSC.
The data is supplied to the score performance data generation circuit 46 in the.

The highest score signal MX is also supplied to flip-flop 50 via OR gate 114 to reset it.

Therefore, the game state signal GM'S'T becomes "O" as shown in FIG. 3, and the output of the inverter 38 in FIG. Since it is in the state reset by GMST, its output page = “1” and the output of inverter 38 =
The AND gate 44 which inputs "i" has an output =
It generates "1" and supplies it to the score performance data generation circuit 46 as an enable signal EN. Incidentally, when the game state signal GMCT becomes "0'°, the counters 62 and 88 are set, and the game circuit GO becomes non-conductive.

The score performance data generation circuit 46 receives an enable signal EN.
When receiving the high score signal H3C=1'' and the high score signal H3C=Pa1, the high score performance data stored in the ROM etc. are sequentially read out 17 and supplied to the tone forming circuit 20 as performance data PFD. The musical tone forming circuit 20 forms a performance sound signal based on the supplied high score performance data and sends it to the speaker 22.
Since the high score performance sound is supplied to the speaker 22, high score performance sound is emitted from the speaker 22.

The end detection circuit 48 detects the end of reading performance data in the circuit 46 and generates a score performance end signal SCE, and this signal SCE is sent to the flip-flop 1 in FIG.
12 is reset. As a result, as shown in FIG. 3, the score performance (high score performance in this example) that started when the game state signal GMCT became "0" is synchronized with the generation of the score performance end signal SCE. It will end.

The timer circuit 116 is provided to regulate the game time, and when the game state signal GMCT becomes l'', the reset is canceled via the inverter 118 and the OR gate 120, and the timer circuit 116 starts counting the predetermined game time. Then, when the output pulse FT is not generated from the counter 86 within the game time (there is no score), the game end signal GE="l" is generated from the timer circuit 11B at the end of the game time. This game end signal GE causes the flip-flop 50 to be reset via the OR gate 114 in the same way as the above-mentioned highest score signal MX, so the game state signal GMCT becomes 0''. For this reason, the counter 62. When H is reset), the gate circuit 60 becomes non-conductive, and the timer circuit 11
6 is also reset. In addition, in the circuit 32 of FIG. 2, an AND gate 44 is connected to the score performance data generation circuit 46.
An enable signal EN=“1” is supplied from the ROM. At this time, the high score signal H3C is OP, and the circuit 4B reads out the low score performance data stored in the ROM etc. and supplies it to the musical tone forming circuit 20. The forming circuit 20 forms a performance sound signal based on the supplied low score performance data and supplies it to the speaker 22, so the low score performance sound is emitted from one speaker 22.Then, the low score performance ends. It is stopped in synchronization with the generation of signal SCE.

If a point is scored within the predetermined game time,
Each time the counter 86 generates an output pulse PT, the timer circuit 11B is reset via the OR gate 120, and the game time measurement is restarted from this reset time.

As a result, the game time is extended beyond the predetermined time.

Note that the timer circuit 1 is also activated when no points are scored during the game time when timing is restarted according to the output pulse FT.
．． 1[1, the game end signal GE is generated, and the same operation as in the case of no points is performed.

[Modifications] This invention is not limited to the embodiments described above, but can be implemented in various modified forms. For example, the following changes are possible.

(1) The musical tone characteristics specified according to the score.

In addition to tones, effects such as sustain effects and vibrato effects may also be used.

(2) The tone color etc. may be changed not every 30 points but every 1 point.

(3) As the pitch specifying means, a keyboard dedicated to the game may be provided instead of using the keyboard of an electronic musical instrument.

(4) Rather than proceeding with the condition of -.match, the game may proceed regardless of -.match/mismatch.

(5) The musical tone characteristics may be directly designated by the matching output of the comparing means.

[Effects of the Invention] As described above, according to the present invention, musical tone characteristics such as timbre and effects are changed according to the score for a musical tone signal having a pitch as one problem, so even beginners etc. You can also easily recognize the level you have achieved through your hearing. Therefore, since there is no need to look at the score display, the game progresses smoothly, and since the score display is not required, the panel configuration can be simplified.

Furthermore, if the sound characteristics such as timbre and effect of the matching sound signal are changed according to the score, the achievement level can be more easily recognized.
