FIG. 6 and FIG. 6 are explanatory diagrams of the absolute time display lyrics data in the present embodiment.

The operation of the karaoke music data conversion apparatus according to the present embodiment having the above-described configuration will be described.

In FIG. 1, performance data 1 stores performance data for reproducing a tone, and lyrics data 2 stores lyrics data for displaying lyrics and changing the color of the lyrics. The time information extracting means 3 reads the data of the performance data 1 and extracts performance information relating to time. The lyric character clock conversion means 4 uses the performance information extracted by the time information extraction means 3 to convert the lyric character clock, which is the unit time of the lyric character, into an absolute time. Lyrics data conversion means 5
Reads out the lyrics data from the lyrics data 2, converts the lyrics data into an absolute time display using the lyrics character clock converted by the lyrics character clock conversion means 4, and outputs it in a text file format (hereinafter referred to as absolute time display). Lyrics data). The absolute time display lyrics data 6 stores the lyrics data converted by the lyrics data conversion means 5.

In FIG. 2, performance data 1 and lyrics data 2 are the same as in FIG. The sequencer 7 reads out the performance data from the performance data 1, rearranges the data in chronological order, and provides the musical tone synthesizing means 8 with sound generation information including a pitch, a volume and a sound generation timing. The tone synthesizer 8 synthesizes a tone according to the output of the sequencer 7. The lyrics display control means 10 reads out the lyrics data from the lyrics data 2 and controls the display of the lyrics characters in accordance with the instructions for displaying the lyrics and changing the lyrics color. The synchronizing signal generator 9 sends a synchronizing signal to the sequencer 7 and the lyrics display control means 10 to synchronize the musical sound with the lyrics characters.

Next, the performance data stored in the performance data 1 will be described.

The performance data 1 stores performance data for reproducing musical tones and conforms to a standard MIDI file format (hereinafter referred to as SMF) (“S
MF Reference Book, Ritto Music). Most of the SMF has a structure of timing information + event, and the event includes “MIDI event”, “system exclusive event”, and “meta event”. MIDI events are individual CHs
The message is for controlling (channel), the system exclusive event is for storing information unique to the manufacturer, and the meta event is used for storing information other than MIDI. In other words, it is MID that controls each CH
Control is limited to the I event, and control for each CH cannot be performed in the remaining two events.

As shown in FIG. 3, the musical performance data includes M
Note events, programs and IDI events
Each information of a change event and a pitch bend event is described.

The note events include a note-on event corresponding to an operation of "pressing a key" of a keyboard and a note-off event corresponding to an operation of "release a key". A CH number, a note number (pitch), and a velocity (volume) indicating one CH of the musical tone synthesizing means 8 are written in each of them. Specifically, notes
The on event is data expressed by <note on event status: 9nh (n is CH, h is a hexadecimal number)><notenumber><velocity>.
Note-off event is <Note-off event status: 8nh (n is CH, h is hexadecimal)
><Notenumber><velocity>. A note-on event with a CH number of 3, a note number of 10, and a velocity of 20 is <93
h><10><20>. The note-off event is similarly expressed, and is actually expressed as a pair with timing information. The timing information will be described later.

The program change event is for switching musical instruments, and a CH number for switching musical instruments and a program change number corresponding to the musical instrument to be switched are written. Specifically, it is expressed by <program change event status: Cnh><program change number>.

The pitch bend event is used to change the pitch, in which a CH number and pitch bend information are written. Specifically, it is expressed by <Pitch bend event status: Enh><Lower byte of pitch bend information><Higher byte of pitch bend information>.

The timing information used as a pair with each event is called "delta time" and is expressed by a time interval between two adjacent events, and its time unit is S.
It is defined by the time unit setting of the MF header / chunk. Although multiple expressions are possible, they are usually set at quarter note resolution. For example, when it is defined as “96”, when the time interval between two events is a quarter note, the delta time is “9”.
6 ", and in the case of an eighth note, it is expressed as" 48 ".

The performance data as described above is stored in the performance data 1.

Next, the lyrics data stored in the lyrics data 2 will be described. The lyrics data differs depending on the creator, and the details are often not disclosed. In many cases, the lyrics data are stored in a binary file format so that the data cannot be easily changed. FIG. 4 shows an example of the lyrics data. In the present embodiment, it is assumed that the lyric character clock, which is a time unit when controlling the display of the lyric character, is the delta time of the SMF. As shown in FIG. 4, the lyrics data is composed of a delta time, a data type, and data, and has a format capable of displaying two lines of lyrics characters.
The delta time is equivalent to the delta time of the performance data, and the data type represents the lyrics character processing contents in one alphabet. Data type "A" starts the display of the first line lyrics characters, "B" starts the display of the second line lyrics characters,
"E" indicates lyric character deletion, "S" indicates color change start, "F"
Indicates the end of the color change. In accordance with the instruction of the lyrics data, the lyrics display control means 10 can display the lyrics and change the color. Here, an example is shown in which “Aoi” is displayed on the first line and “Eo” is displayed on the second line. In FIG. 4, (1) after the start of the performance, "192"
After "0" delta time, the lyric character "Aoi" on the first line is displayed. (2) After "0" delta time when "Ai" is displayed, that is, at the same time as the first line, the lyric character "Eo" on the second line is displayed. "
Is displayed. (3) The color change of “A” starts after “198” delta time when the lyrics of the first and second lines are displayed, and (4) The color change of “A” ends after “96” delta time after the start of color change. . (5) After “0” delta time after the end of the color change of “A”, that is, at the same time as the end of the color change of “A”, the color change of “I” starts, and (6)
After the start of the color change of “I”, the color change ends after a “144” delta time. (7) After the “0” delta time of the end of the “i” color change, that is, at the same time as the end of the “i” color change, the “u” color change starts, and (8) “48” after the “u” color change start The color change ends after the delta time. Then, (9) after the delta time “10” after the color change of “Ai” in the first line is completed, the “Ai” in the first line
To delete.

The lyrics data as described above is stored in the lyrics data 2.

The time information extracting means 3 extracts from the performance data 1 information necessary for converting the lyrics character clock in the lyrics data into an absolute time. Here, the lyric character clock has the same delta time as the performance data. Therefore, the “time unit” value in the header chunk of the SMF that defines the resolution of the delta time, and the “set time” for setting the tempo.
The tempo value is extracted and output to the lyrics character clock conversion means 4.

The lyric character clock conversion means 4 calculates the delta time which is the lyric character clock from the "time unit" value which is the resolution of the delta time input from the time information extraction means 3 and the "set tempo" value. Convert to time.
Since the delta time has been described above, the set tempo will be described. The set tempo is set in the SMF meta event. Specifically, <FF><51>
<03> Expressed as <tttttt> and paired with delta time. This value indicates the length of a quarter note in μ seconds. For example, it is assumed that the resolution of the delta time is “96” and the tempo is “106 [microseconds]”. That is,
Since the tempo is 1 [second], the length of the quarter note is “1”.
[Second] ”and the delta time is“ 1/96 [second] ”.
Outputs “1/96 [second]”.

The lyric data conversion means 5 reads the lyric data from the lyric data 2 and converts the lyric character clock conversion means 4
The time information is displayed in absolute time using the output of, and output in a text file format. Hereinafter, this output file is referred to as absolute time display lyrics data. The delta time output from the lyrics character clock conversion means 4 is “1/96
[Second] ”, the lyrics data 2 shown in FIG.
Convert the delta time of the lyrics data read out from to the absolute time and write it out in a text file format. In this embodiment, the absolute time is changed from “0 minute: 0 second: 0 millisecond” to “0 minute”.
0: 00: 000 ". FIG.
(1) is “1920” delta time.
0/96 = 20 [seconds]. Similarly, when the delta time is converted to the absolute time, the result is as shown in FIG. Although this may be used as it is, in this embodiment, the converted data is output as absolute time display lyrics data so that the user can intuitively understand it.
That is, the instructions are arranged in chronological order from the top of the file, and when the order of the instructions is determined, the instructions are omitted. Specifically, the color change of the lyric character is always performed in the order in which the lyric characters are arranged, after the instruction to start the color change of the first character is given, and then the instruction to change the color of the lyrics is given, and then the instruction to change the lyric color of the second character is given. As shown in FIG. The time display is indicated by the absolute time from the start of the performance, and the information on the lyrics color change is displayed by pairing the color change start time and the time interval from the start to the end. As a result, in the lyrics data read from the lyrics data 2, the data indicating the color change information divided into two times has been combined into the data to be output to the absolute time display lyrics data 6 into one instruction. Hereinafter, FIG. 5 and FIG. 6 will be compared. FIG. 5A, which indicates the display of the first line lyrics, corresponds to FIG. 6A, and FIG. 5B, which is the second line lyrics display, corresponds to FIG. 6B. . "Ah"
(3) and (4) in FIG. 5 correspond to (c) in FIG. 6, and the same applies to “I” and “U”. (9) in FIG. 5 instructing erasure of the lyrics on the first line corresponds to (f) in FIG. Hereinafter, the same applies.

The lyrics data converted as described above is output in a text file format and stored in the absolute time display lyrics data 6.

In this embodiment, since the lyric character clock is set to delta time, the data extracted by the time information extracting means 3 is a "time unit" value and a "set tempo" value which are the resolution of the delta time. However, for example, when the lyrics character clock is bar information, the time information extracting means 3 needs time signature information and the like in addition to the "time unit" value and the "set tempo" value which are the resolution of the delta time. become,
The information to be extracted differs depending on the lyrics character clock.

In the present embodiment, the lyrics data of the absolute time display lyrics data 6 display the time information as the total time from the start of the performance, but may display it as a time difference.

Furthermore, in the present embodiment, the karaoke song data is converted and the lyrics edited are played back by the karaoke playback device. However, the karaoke song data conversion can be performed by the karaoke playback device. Any karaoke playback device that can input characters can also edit data.

As described above, according to this embodiment, the lyrics data 2 is converted by the lyrics data conversion means 5 from the musical display called delta time to the absolute time by the lyrics data conversion means 5. In addition, the format can be easily understood by general users without music knowledge. Also,
By outputting in the most common text file format, an editing environment can be easily obtained, so that many people can enjoy it.
