The ROM 21 stores a system program, a sequence program, a game program, a loader, and pattern data. The system program is a program for controlling the basic operation of the apparatus and data transmission / reception with peripheral devices. The sequence program is a program that drives the sound source 29, the audio data processing unit 30, the DSP 31 and the like based on the music data, generates karaoke performance sounds, and controls the display of lyrics and the reproduction of background video. The game program is a program that displays a game screen on the monitor 39, advances a frame according to an operation by the user, selects a karaoke song, and determines a performance mode. The loader is a program for downloading music data from the distribution center. The pattern data includes character pattern data (font data) for displaying lyrics, song titles, and the like, and graphic patterns for displaying game graphics. The communication control unit 26 is a controller for communicating with the distribution center via a communication line and downloading music data and the like. The communication control unit 26 has a built-in DMA circuit, and can directly download downloaded music data to the HDD 27 without using the CPU 20.
[0009]
An effect device 40 such as a lighting device or a confetti device is connected to the MIDI interface 28. This peripheral device is controlled by peripheral device control data included in the music data. That is, during the performance of a karaoke song, the color of illumination and the illuminance are controlled so as to meet the atmosphere and progress of the song.
[0010]
The commander receiving unit 23 receives the infrared signal sent from the commander 41 and restores the data. The commander 41 includes various key switches such as command keys such as normal mode keys and game mode keys, and numeric keys. When the user operates these key switches, the commander 41 outputs an infrared code signal corresponding to the operated key switch. The commander receiving unit 23 receives this infrared code signal and transmits it to the CPU 20. The operation unit 24 is provided on the front panel of the karaoke device, and includes a mode selection switch and a numeric keypad similar to those of the commander 41. The display unit 25 is also provided on the front panel of the karaoke apparatus, like the operation unit 24, and includes an LED matrix display that displays the number of the currently played song, the number of reserved songs, and the like.
[0011]
The sound source 29 forms a musical tone signal based on the musical tone data included in the music data. The audio data processing unit 30 reproduces an audio signal such as a back chorus based on the audio data included in the music data. The tone signal formed by the sound source 29 and the sound signal reproduced by the sound data processing unit 30 are input to the DSP 31. The DSP 31 imparts effects such as reverb and echo to these musical sound signals and audio signals. The type and degree of the effect provided by the DSP 31 is controlled based on the DSP control data included in the music data. The musical sound signal and sound signal to which the effect is applied are converted to an analog signal (karaoke performance sound) by the D / A converter 33 and then output to the amplifier 33. A singing voice signal is also input from the microphone 34 to the amplifier 33. The amplifier 33 mixes and amplifies the karaoke performance sound and the singing voice signal to drive the speaker 35.
[0012]
The pattern development unit 36 develops a character pattern on the screen corresponding to the character code data of the lyrics track and creates a game screen in the game mode. The LD changer 37 reproduces a predetermined background video (moving image) during karaoke performance. The character pattern developed by the pattern development unit 36, the game screen, and the background video reproduced by the LD changer are combined by the display control unit 38 and displayed on the monitor 39.
[0013]
In the normal mode, when the user operates the commander 41 to input a song number, the song number is displayed on the display unit 25, and the corresponding song data is read from the hard disk 27 to the RAM 22. Then, each track of the music data is read based on the tempo clock, and the read event data is transmitted to the sound source 29, the audio data processing unit 30, and the DSP 31, whereby a karaoke performance sound is formed, and the lyrics display event The lyrics are displayed by transmitting the data to the pattern development unit 36. On the other hand, in the game mode, a graphic game screen is created according to the instructions of the game program.
[0014]

In the case of a game, it is determined how much the song can follow the melody. Then, a score is given with a maximum score of 100, and this is output to the CPU 20. When the game is executed, the CPU 20 determines the progress of the frame according to the score.
[0015]
FIG. 2 is a diagram showing an example of music data. FIG. 2A shows the overall composition of the music data, and FIG. 2B shows the structure of the melody track included in the musical tone track. The music data is composed of a header, a musical sound track, a lyrics track, a sound control track, a DSP control track, a peripheral device control track, and a sound data section. The header is a portion in which various data relating to the music data is written, and data such as a music title, genre, release date, and performance time (length) of the music is written.
[0016]
The musical tone track, lyrics track, voice control track, DSP control track, and peripheral device control track are all described in the MIDI format as shown in FIG. The MIDI format includes a plurality of event data and duration data Δt indicating a time interval between each event data. The sequence program counts Δt at a predetermined tempo clock, and when Δt is counted up, reads the event data that follows it and outputs it to a predetermined processing unit.
[0017]
The musical sound track includes a melody track and a rhythm track as well as various parts. The performance event data in the melody track shown in FIG. 5B includes musical tone generation (note-on event), musical tone mute (note-off event) data, etc., event type (note-on, note-off, tone change, etc.), note It consists of data such as number (pitch) and velocity.
[0018]
When a sequence is performed with such track data, the tempo can be slowed by processing the value of the duration data Δt longer, and the tempo can be speeded up by processing the duration data Δt smaller. Also, by rewriting the note number, you can change the key or change the tonality.
[0019]
The lyrics track is a track that stores sequence data for displaying lyrics on the monitor 39. This sequence data is not musical sound data, but this track is also described by a system exclusive message in the MIDI data format in order to make the implementation uniform and facilitate the work process. The audio control track is a sequence track for designating the generation timing and reproduction pitch of audio data stored in the audio data section. The voice data section stores voices such as back chorus and harmony singing that are difficult to synthesize with the sound source 29. In the DSP control track, DSP control data for controlling the operation of the DSP 31 is written together with duration data. In addition, data for controlling the color and brightness of illumination is written in the peripheral device control track.
[0020]
FIG. 3 is a view showing a screen of a sugoroku game which is a game executed by the karaoke apparatus. The board surface 45 of the sugoroku game is formed by arranging a plurality of cells 51 between the start 50 and the goal 52. Each square 51 describes the selection conditions for karaoke songs such as enka, pop, foreign songs. A plurality of frames 60 are displayed on the sugoroku board. Each frame 60 is displayed in a different color. At the start of the game, all the pieces are placed on the starting square. Each user (player) of the karaoke apparatus is in charge of one frame. Each player arrives at the goal as soon as possible while following his own rules.
[0021]
4 to 9 are flowcharts of the game program of the karaoke apparatus. The progress of the game will be described with reference to this flowchart.
[0022]
FIG. 4 shows the main routine of the game program. When the game starts, first, a game start processing operation is executed (s1). In FIG. 5, in the game start processing operation, each player first inputs a name (s11) and receives designation of a frame color (s12). For example, the colors of the frames are red, orange, yellow, green, blue, indigo, purple, etc., and the order of play is determined in this color order. The color in the previous order is specified in the order in which the names are entered. When everyone's registration is completed, the first karaoke song is performed.
[0023]
First, the player selects the song that he wants to sing the most. The karaoke apparatus stores this song number in association with the player name in order to play this song even at the goal (s14). Then, only one chorus of this song is played (s15). In order to sing this song, the player detects and stores the range of the player by this singing (s16) and scores the song. The scoring method may be a general method. Based on this scoring result, the progress of the frame (the number of cells to advance) is determined (s17). The frames displayed on the monitor 39 are advanced by this number (s18). When the processing from s14 onward is completed for all players, the game start processing is finished and the process returns to the main routine.
[0024]
Next, the second and subsequent processes are executed for each player (s3). In FIG. 6, a plurality of cards corresponding to the place where the playing player's piece is stopped are displayed face down and shuffled (s21). This shuffling is continued until the player instructs opening (s22). When opening is instructed, the card at the top at that time is turned to the front and the contents are displayed (s23). All of the above processes are executed as graphics on the screen of the monitor 39. The player's open instruction may be given by the commander 41 or the like.
[0025]
The contents of the card are as follows, for example.
[0026]
"Sing at 1.5 times the tempo"
"Sing at half tempo"
"The tempo changes randomly"
"Raise it five times and sing"
"Sing it down five times"
"Keys change randomly"
"Please sing in major / minor"
Etc. The karaoke device stores this content (s24), and changes the karaoke performance according to this instruction during the karaoke performance. Note that switching between major and minor keys is a game, and it is sufficient to simply raise and lower the sound of “mi” by a semitone. Moreover, you may create the card | curd which combined said conditions. The contents of this card and the genre of the song written on the cell are the singing conditions for this player. Therefore, for example, singing conditions such as “Sing Enka in tempo with a fast tempo” or “Sing in the best 10 of this week 5 times and sing in minor” are set.
[0027]
In s25, the music selection process is executed. This music selection process is a process in which the player selects one song from the genres specified by the squares. In FIG. 7, it is first determined whether or not one song has already been determined (s31). The case where one song has been decided is the case where the title of the song is directly written on the square, or when only one song is indicated, such as “This week's best 1” or “Last year's record award” It is. In this case, the process returns directly based on the determination at s31. In other cases, the NG counter is set to 0 (s32). The NG counter is a counter that is counted up when a song having a designated condition (genre) is not selected. In step s33, a song selection (input of a song number) is accepted, and it is determined whether the song number is a song that meets the designated condition (s34). If the condition is met, return that number. If the condition is not met, 1 is added to the NG counter (s35), and if the NG counter is less than 3, the music selection is accepted again (s33). When NG becomes 3, the player's frame is returned to the start (s37), and the processing operation (FIG. 6) after the second round of this time is finished (s38). Thus, for example, by describing difficult-to-understand music selection conditions such as “Record Grand Prix of the Showa 40s”, the music selection itself can be made into a game.
[0028]
In FIG. 6, the music selected in s25 is played under the performance conditions of s24 (s25). FIG. 8A shows the basic operation of the performance execution process, and FIG. 8B shows the timer interrupt process during performance execution. In FIG. 1A, the music data of the selected music is first read into the RAM 22 (s41), and a karaoke performance sequence is started (s42). At the same time, the play flag is turned on. Then, it waits until the play flag is turned off by a timer interruption operation described later (s43).
[0029]
In FIG. 8B, this operation is executed by a tempo clock interrupt while the play flag is on. First, 1 is subtracted from Δt indicating the time interval of the sequence (s45). If Δt becomes 0 by this subtraction, the operation from s47 is executed, and if it does not become 0, the operation returns as it is (s46). However, this operation is executed in parallel for all tracks included in the music data.
[0030]
When Δt = 0 and the operation proceeds to s47, the next data is read from the corresponding track. Then, it is determined whether this data is event data, end data or duration data (s48, s49). If it is event data, this data is changed according to the performance condition (s50), and is output to the corresponding operation unit (s51). Thereafter, the next data is read again (s47). The change of the data is, for example, a change such as adding 7 to the note number data indicating the pitch and raising it by 5 degrees. Thereby, a karaoke performance can be changed to meet conditions. If it is end data, all the tracks are muted (s52), the play flag is turned off (s53), and the process returns. It is assumed that this end data is written in one track among all the tracks of music data. If it is duration data, it is changed according to the condition (s54), the changed value is set in the Δt register (s55), and the process returns. The change of duration data is, for example, halving the size and doubling the tempo.
[0031]
In FIG. 6, when a karaoke performance is performed by the performance execution process (s26) and a karaoke singing is performed at the same time, the singing is scored by a grader (s27). In the above karaoke performance, the tempo and key are changed, so whether the following singing is performed is subject to scoring. The progress of the top is determined based on the scoring results. The correspondence between the scoring result and the progress of the frame is set as shown in FIG. 10, for example. As shown in the figure, if the score is high, the piece advances up to three, but if the score is bad, the piece is moved backward, and if it is extremely bad, the piece is returned to the starting point. Can be linked. The frame is advanced by the number of cells determined in this process (s28), and the process returns to the main routine.
[0032]
In FIG. 4, it is determined whether or not the player has scored as a result of the advance of the frame in the second round and subsequent processing (s2) (s3). When a goal is reached, goal processing is performed (s3 → s4). If the goal is not reached, the order is passed to the next player (s6), and the second and subsequent processes (s2) are executed for the player. Also, after performing the goal process (s4), it is determined whether or not everyone has scored (s5). If everyone has scored, the game is terminated. If all have not yet scored, Then, the order is passed to the next player (s6), and the second and subsequent processes (s2) are executed for the player.
[0033]
Here, the goal process (s4) will be described. FIG. 9 is a flowchart showing goal processing. In the goal processing, a song selected by the player at the start and only one chorus is sung (see s14 and s15 in the game start processing) is congratulated on the goal, and effects such as full chorus, mirror ball, confetti, and clapping roar It is an operation to sing along with. In FIG. 9, first, the music played at the start is again read into the RAM 22 (s60). Then, the effect device is activated (s61), and the karaoke song is played as a full chorus (s62).
[0034]
In this Sugoku board, there is no branching of the route, but it may be branched. However, in order to link with karaoke performance, it is preferable not to complicate the sugoroku game more than necessary.
[0035]
The contents of the game and the instructed music selection / performance (singing) conditions are not limited to those described above. In the above embodiment, the music selection condition (genre) is displayed on the square and the performance condition is selected by turning the card. However, the music selection condition may be displayed on the card, and the performance condition is displayed on the square. You may make it do.
[0036]
Further, in the above embodiment, the progress of the frame is determined based on the singing scoring result, but in addition to this, a dice or a roulette is displayed on the screen, and the progress may be determined by operating this.
[0037]
【The invention's effect】
As described above, according to the present invention, the game and the karaoke singing can be linked, so that the karaoke singing can be performed as a part of the game while enjoying the game, so everyone can enjoy both the game and the karaoke. it can.
