The karaoke apparatus can be configured to receive and store song data from a host, but the description of the necessary data reception and transmission units is omitted. The operation will be described below. At the time of a normal karaoke performance, when a performance music is designated by the operation of the controller 6, the CPU 1 refers to the music list stored in the storage device 4 and encodes the music data of the performance music and the back chorus. The transferred audio data is transferred to the RAM 2 and the control is transferred to the sequencer 15. Sequencer 15
Is based on multiple event data included in song data,
Simultaneously execute a plurality of events including music performance in parallel. That is, the sequencer 15 sends data relating to the timbre, pitch and sound of the musical instrument to the sound source 14, the encoded audio data to the digital audio decoder 16, and the background video number to the background video recording / reproducing unit 7. And the image designation information for displaying the lyrics are supplied to the image / lyrics forming unit 8. As a result, the background image is displayed on the entire surface of the monitor 10 and the lyrics are superimposed on a part of the background image, while the speaker 13 is in a performance state in which the performance music and the back chorus are output. As shown in FIG. 2, the music data includes a header section,
It consists of a data sequence section and an audio data section. In the header portion, a song number, a song name, a composer name, a singer name, background image selection information, and font selection information for lyrics are written as information unique to the song. In the data sequence portion, a plurality of tracks describing a plurality of types of events that are executed in parallel and simultaneously are set. A plurality of pieces of audio information selected by the audio data instruction track of the data sequence section are written in the audio data section. Among the tracks included in the data sequence portion, the performance data track describes in time series data that causes the tone generator 14 to emit the musical tones of the performance music. In the pseudo sound data track, data for generating a pseudo chorus sound (for example, "Wow" or "Wow") from the sound source 14 is described in time series. In the audio data instruction track, an audio data number indicating a chorus audio to be decoded by the decoder 16 (for example, “Hakodate” or “Nagasaki”),
The pitch and pitch data are described. In the lyrics data track, data indicating lyrics to be displayed on the monitor 10 along with the performance is described in time series. In the effect control data track, control data for controlling the mixer and the effector 12 is described in time series. FIG. 3 is an explanatory diagram showing details of the performance data track. The performance data track events include a note event, a tone change event, and a pitch vent event. In the note event, a CH number, a note number (pitch), a velocity (volume), and a note length indicating one CH (channel) to be sounded by the sound source 14 are written, and correspond to this event. By transmitting the command (data) to the sound source 14, a musical tone having a predetermined tone color, pitch, and volume can be generated according to a predetermined note length. A CH number and tone color data are written in the tone change event, so that a predetermined CH tone can be changed. CH number and pitch bend information are written in the pitch bend event, whereby pitch bend effect control of a tone assigned to a predetermined CH can be realized. FIG. 4 is an explanatory diagram showing details of the audio data instruction track and the lyrics data track. In the audio data instruction track, each information of the audio instruction event is described. That is, the information includes the audio data number, the pitch, and the volume. The audio data number is the number of the encoded audio data to be decoded by the decoder 16, and is the audio number of the audio data in FIG. In the lyrics data track, information of the lyrics event, that is, display character data, display time, and a wipe sequence are described. The display character data includes a character string to be displayed on the monitor 10, generally a type of display character for one phrase, and an address number on the monitor for displaying each character. The display time is time information indicating the time during which the display character string is displayed. The wipe sequence is
This describes a procedure for sequentially changing the display color of a character string being displayed in the progress direction of a music piece in synchronization with the progress of a music piece. As shown in FIG. 5, all the tracks have a structure in which the types of events and the waiting time ΔT until the next event occurs are arranged in time series. When playing a game with the karaoke apparatus, the controller 6 specifies the type of the game. In this case, the CPU 1 stores the corresponding game program in the HDD.
4 to the RAM 2. This game program is R
When developed to AM2, the sequencer 15 controls game processing, not normal karaoke performance. Various game programs are conceivable. FIG. 6 is a processing flow of a game in which the lyrics are not displayed and the music is performed while changing the tempo of the music, and the title of the music / composer / singer is applied. When this program is started, initialization is performed in step S1. In the next step S2, the difficulty level is input from the controller 6. The "difficulty level" is difficult to understand, and for example, the lower the request frequency, the higher the difficulty level. In practice, each terminal temporarily stores the number of requests for each music piece (terminal frequency file), and when exchanging information with the center, such as distributing new songs, transmits the frequency file of each terminal to the center. A frequency file is created by summing the results.
The frequency file indicating the degree of difficulty is downloaded in advance to the HDD 4 when distributing a new song from the center and used, or the frequency file is created (updated) on the karaoke apparatus side from the actual number of requests. . Since a plurality of music pieces having the same frequency are registered in the frequency file, a music piece is automatically selected from them in step S3. Here, when one song is selected, the CPU
1 transfers the corresponding music data and the reproduction tempo rule from the HDD 4 to the RAM 2 in step S4. In step S5, the sequencer 15 starts playing based on the music data written in the RAM2. At this time, the lyrics data track is not reproduced. That is, the lyrics forming unit 8
The lyrics display on the monitor 10 is prohibited by not transferring the lyrics data to the monitor 10. Also, the performance is a part of the music, for example, only one phrase of the intro part, but the audio data for the back chorus is not reproduced. The music is performed while changing the tempo over time according to the reproduction tempo rule. FIG. 8 illustrates two reproduction tempo rules. (A) is an example in which the tempo is linearly reduced from the start of the performance and eventually becomes the standard tempo. (B) is an example in which the tempo is curvedly reduced from the start of the performance and eventually becomes the standard tempo. These examples are
Although this is an example in which the tempo is shifted from a tempo faster than the standard to the standard tempo, a playback tempo rule that shifts from a tempo slower than the standard to the standard tempo may be used. In step S6, the timer for answering the time limit is started simultaneously with the start of the performance. In step S8, it is monitored whether there is any data input from the controller 6 within the time limit. If there is no data input, the process returns to step S7. If there is, however, it is determined in step S9 whether the input number is equal to the music number ( This example is a game in which a “song name” is applied by a “song number”. If they are not equal, an incorrect answer process is performed in step S10, and the process returns to step S7. If they are equal, the process branches to step S12 to display the answer. If the timer count exceeds a predetermined value (exceeds the time limit) in step S7, the process proceeds to step S11, and it is determined whether an answer display is necessary. When the elapse of the time limit is the first time, the process proceeds to step S15, where the performance including the lyrics data is restarted, and the timer is restarted in step S6. That is, in the second time, the tune is played while the lyrics are displayed on the monitor 10, and the tune name is applied. The second performance may be at standard tempo or variable tempo. If it is determined in step S7 that the second time limit has expired, it is determined in step S11 that an answer display is necessary, and the process proceeds to step S12. Step S1
In step 2, the correct song title is displayed on the monitor 10. In the next step S13, scoring and other processes are performed, and in step S14, it is determined whether or not the game is over. If it is determined that the game is over, an end process (END) is performed. If it is determined that the game is not over, the process returns to step S3 to select the next song. FIG. 7 is an example of a song name answer input screen displayed on the monitor 10 by display control included in the game program. In this example, up to four persons can use the controller 6 to input an answer. PLA
Y1 to PLAY4 indicate the input screens of the respective respondents, and scores 0, 5, 10, 20 and the like are displayed as scores next to them. This example shows a music piece input screen of each player when the music piece name "Seriously Mysterious" is the correct answer.
The character input is converted into a song number and compared in step S9 in FIG. In the display example, the PLAY1 person does not know the correct answer, and the cursor has not moved from the "a" part of the Japanese syllabary display. Since the person of PLAY2 knows the correct answer, “Kikikaikai”, the cursor is located at “KA” in the middle of moving the Japanese syllabary cursor to “KI”. The person on PLAY3 has moved the cursor to "", and at this stage, the controller 6
Press the OK button to display PLAY from the 50-sound screen.
The screen switches to a song name list screen, such as 4, which starts with "ki". The player moves the cursor up and down on the song list screen and presses the enter button, and the answer converted to the song number is compared in step S9 in FIG. In the above example, the game in which the song name is applied has been described. However, the game in which the lyrics, composer name, singer name, and the like are applied can be implemented in the same manner. As described above, according to the present invention, in a karaoke apparatus having a function of displaying lyrics on a monitor as the music is played, the lyrics are not displayed on the monitor and the tempo of the music is not changed. Karaoke apparatus that enables a game in which the player plays a song while changing the song title and assigns lyrics or song titles.
