Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a music playback device that plays back music based on music information stored in a storage medium, and particularly to a music playback device that selects a playback range of one piece of music and continuously plays back music based on music information stored in a storage medium. The present invention relates to a music playback device with a shortened playback function.

[Prior Art] In recent years, musical tone reproduction devices that use a musical tone information storage medium that stores musical tone information of a large number of songs, read out the musical tone information stored therein, and reproduce musical tones have been used in, for example, karaoke machines. Generally widespread.

In conventional karaoke machines, the singer first selects a song title, and then selects the medium (e.g. cassette tape, compact disc, etc.) on which the musical information for that song is recorded.
is set on the karaoke machine. Then, in order to play a desired song from among the song titles recorded on the set media, the number corresponding to the desired song is input from the input means for specifying the song, and the karaoke machine responds to this human input signal. Based on this, the recording position in the medium is recognized, and the desired song is played back in the playback section.

Generally, the musical tone information for each song recorded on the media includes enough playback information for a singer to sing a full chorus (usually, for example, the first to third verses). Therefore, the music to be played starts with the prelude and continues with the accompaniment sound of the full chorus.

In addition, in recent years, it has become necessary to purchase new media such as disks every time a new song is released, so the number of disks, etc. has to increase as the number of songs increases. In view of this, a device has been developed in which the musical tone information of a large number of songs is stored in advance as digital data in a musical tone information storage medium (such as a disk) provided within the device body. According to such a device, when a new song is released, the number of songs can be increased by writing the new data to this musical tone information storage medium, and the problem of an increase in the number of media does not occur. do not have.

General 1: MID (Musical Instrument) data is stored in this musical sound information storage medium.
rumentDigital Interrace)
(rMIDIJ is a registered trademark) Applications using information have also been filed. This is internationally standardized information that indicates timbre, pitch, volume, etc. That is, this MIDI information is read out and predetermined accompaniment music is played back by a musical sound playback device such as a synthesizer via a MIDI interface.

Even with a karaoke device that uses such a musical sound information storage medium, just like the karaoke device that uses the above-mentioned normal media, when a song is selected, the accompaniment is played back so that the full chorus of that song can be sung. It has become.

[The problem that the invention attempts to solve! i] However, as mentioned above, with conventional karaoke equipment,
The smallest unit a singer could select was a song, so if a singer selected a song, he or she had to sing the full chorus of that song.

Therefore, when a plurality of people use one karaoke machine at the same time, there is a problem in that the accompaniment music for the full chorus of all the songs is played, resulting in a long time spent waiting for their turn to sing.

However, some singers do not wish to sing a full chorus of a convex song, and may think that it is sufficient to sing one or two choruses from the first to third choruses, for example.

That is, there are cases where the user wishes to sing only the first part or only the first and third parts of the song.

In such cases, with conventional devices, in order to shorten the accompaniment of a song, it is necessary to interrupt the song in the middle, for example, by manually or automatically fading out in the middle of the song. All I could do was finish it.

Therefore, since the accompaniment song ends before reaching the second part, the end of the song may be unnatural, and the climax part of the ending part of the song may be omitted, making it difficult for the singer and the listener to fully enjoy the song. The problem was that I couldn't enjoy it.

The present invention has been made to solve the above problems, and its purpose is to arbitrarily cut a predetermined range of musical tone information of each song and continuously reproduce the shortened information. To provide a musical sound reproducing device with a shortened reproducing function capable of singing only a desired part without causing deterioration of accompaniment sound.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the musical tone reproduction device with a shortened reproduction function according to the present invention provides information on each section in which musical tone information of one song is divided into predetermined ranges, and each section. Musical tone information including start instruction data indicating the beginning of each piece of information and end instruction data indicating the end of each piece of information is stored in a musical tone information storage medium, the musical tone information is read from the musical tone information storage medium, and musical tone reproduction is performed based on the read information. The musical sound reproducing device is equipped with a musical sound reproducing unit that performs a music reproduction, and the musical sound reproducing unit includes a reproduction designation input means for selecting and designating the classification information to be reproduced in one song, and a human input to the reproduction designation input means. The apparatus is characterized in that it includes a control section that reads the segment information to be reproduced based on the start instruction data and the end instruction data as indicators, and controls the information to be reproduced continuously.

[Function] According to the above configuration, a user such as a singer can select the classification information to be reproduced with respect to musical tone information regarding one song using the reproduction specifying manual means. That is, by first selecting the classification information of the designated song, the user can select, for example, the classification information of the prelude part, the first chorus part, the third chorus part, and the second part.

Based on this designation, the control section reads the classification information of each song from the start instruction data and end instruction data, and controls the musical tone reproduction to be performed based on the shortened musical tone information. As a result, accompaniment is performed only for the desired chorus part, and the prelude and back part can be played continuously, making it possible to meet the user's needs without deteriorating the accompaniment music. becomes.

[Example] Hereinafter, an example of the present invention will be specifically described based on the drawings.

FIG. 1 shows an example of one stroke of musical tone information stored in the musical tone information storage medium of the present invention.

A feature of the musical tone information of each song of the present invention is that it is divided into predetermined ranges, and in this embodiment, the prelude,
It is divided into each chorus part (from the first verse to the last verse) and the second part.

The musical tone information for this -fraction starts from a musical tone information start position 10, and a prelude section 12 is recorded first. Next to the prelude section 12, a first chorus section (the first verse of the song) 14 is recorded, and at its beginning and end positions, beginning instruction data 14a and 14b are recorded, respectively.

Next to the end instruction data 14b of the first chorus section 14, the start instruction data 16a of the second chorus section 16 is recorded.
Similarly, end instruction data 16b is recorded at the end position of the second chorus section 16. Then, in order, the beginning instruction data 18a of the 3 chorus parts 18, ff13 chorus part 1
8. End instruction data 18b is also recorded, and finally, musical tone information end instruction data 22 indicating the end of the musical tone information of the rear part 20 and the music piece is recorded.

In this manner, the musical tone information of each song recorded on the musical tone information storage medium of this embodiment is recorded with each chorus section sandwiched between the beginning instruction data and the end instruction data.

FIG. 2 is a schematic configuration diagram showing an example of the musical sound reproducing apparatus with the shortened reproduction function of the present invention used as a karaoke apparatus, in which a CD (compact disc) 24 is used as the musical sound information storage medium. This CD 24 records a large amount of musical tone information for each piece of music as shown in FIG.

Note that the method for recording musical tone information on CD24 is P.C.
M (Pulse Code Modulation
) etc. are used. Then, the musical tone information on the CD 24 is read out by the CD player 26. A CPU 28 is connected to the CD player 26, and the CPU 28 is connected to the CD player 26.
The PU 28 functions as a control unit and performs system control of the entire karaoke apparatus.

An input device 30 having a function as a reproduction designation input means is connected to the CPU 28. The input device 30 includes an operation panel and an input buffer, which have keys for selecting a song and keys for instructing information on the category in which the song should be played.

Further, a memory 32 is connected to the CD player 26 and the CPU-28, and the CPU 28 controls the CD player 2-2.
6 stores information read from the CD 24.

Furthermore, the CPU 28 includes a D/D converter for converting the musical tone information read out from the memory 32 by the CPU 28 into an analog signal.
An A converter 34 is connected.

This D/A converter 34 is further connected to an audio amplifier 36, and a microphone 38 and a speaker 40 are respectively connected to this audio amplifier 36.

Next, the operation of the karaoke apparatus shown in FIG. 2 will be explained. First, the user specifies a song. This is done by, for example, specifying the song number by operating keys on the operation panel of the input device 30. Then, the user selects the classification information desired to be played within the specified song. In this embodiment, the prelude part 12 and the second part 20 are configured on the premise that they are always played back, so the selection of classification information is performed by operating a key that specifies the chorus you want to sing among the plurality of chorus parts. conduct. Alternatively, it may be possible to specify a chorus section that is not to be played back. Thereby, the prelude part 12, the chorus part to be sung, and the back end part 20 can be configured as musical tone information of one song.

Note that in the example of musical tone information shown in Figure 1, there is no interlude between each chorus section, but songs with an interlude are naturally separated by this interlude, and the ending instruction is also provided in the same way. The data and head instruction data will be recorded.

Next, the CPU 28 causes the CD player 26 to play a CD.
24, musical tone information about the specified song is read out.

FIG. 3 shows a flowchart of the reading operation of the CPU 28 and the storing operation of the read information in the memory 32 at this time, in which the second chorus section 16 is omitted, and the first chorus section 14 and the third chorus section 18 are omitted. This shows an example of a case where only the following files are played back.

First, the CPU 28 starts reading the musical tone information of the designated music piece from the musical tone information start position 10. Then, the reading is continued until the musical tone information end instruction data 22 indicating the end of the music piece is detected (Sl). Then, the second chorus section 1 is sequentially read out from the prelude section 12 and omitted.
It is detected whether or not the beginning instruction data 16a indicating the beginning of 6 has been read out (Sl). Then, until this leading instruction data 16a is detected (while Sl is NO), musical tone information is sequentially read out and the information is output to the memory 32 (S3), excluding the instruction data portion where musical tones are not reproduced (S3). S4).

That is, in S3, only the musical tone information of the accompaniment tone information portion is sequentially stored in the memory 32, so if it is the instruction data portion (Yes in S3), the information is not output to the memory 32. The process advances to the next pointer (S5).

Then, the step loop from 81 to S5 is performed until the beginning instruction data 16a of the second chorus section 16 is reached, and the musical tone information is sequentially stored in the memory 32. When the CPU 2g detects the head instruction data 16a (Sl is Yes)
, without outputting information from this second chorus section 16 to the memory 32 (without performing S4), proceeding to the next pointer (S6
), end instruction data 1 indicating the end of the second chorus section 16
The next pointer is advanced until 6b is detected (S
7).

Then, when the end instruction data 16b is detected (S7 is Y
es), proceeds to the next pointer (S5), and performs the step loop of 81 to S5, thereby outputting information on the third chorus 58 and the rear gable portion 20. And the second wife part 2
When the storage of the shortened musical tone information to 0 is completed and the musical tone information end instruction data 22 is detected (Sl is Yes), the storage of the shortened musical tone information in the memory 32 by the CPU 28 is completed (END
).

Next, the CPU 28 sequentially reads out the shortened musical tone information 32a stored in the memory 32 and sends it to the D/A converter 34.

The D/A converter 34 converts this shortened musical tone information 32a into an accompaniment tone signal 34m, which is an analog signal, and sends it to the audio amplifier 36. Then, the audio amplifier 36 amplifies and outputs the singer's audio signal 38a inputted from the microphone 38, and generates accompaniment sound and singing voice from the speaker 40.

In this way, according to the karaoke device according to the above embodiment, only the chorus parts (for example, the first and third verses) that the singer wishes to sing of the song selected according to the singer's wishes are continuously performed in a manner that includes the prelude and the second part. The length of a song can be shortened to satisfy the singer's wishes.

The present invention is not limited to the configuration of the above embodiments, and various modifications can be made without changing the gist of the invention. For example, as in the karaoke furnace shown in FIG. 4, the musical tone information recording medium is not a CD but a node disk 42 built into the karaoke apparatus, and a large amount of music information is stored in the hard disk 42 as MIDI information. By storing it as musical tone information as shown in Figure 1,
A similar effect can be obtained.

In the embodiment shown in FIG. 4, a synthesizer 44 is used as a device for converting the shortened musical tone information 32a read out from the CPU 28 into a music signal.

Note that such a karaoke device is connected to an external host device 46 via a telephone line 47 as shown in the figure, and the MID stored in the storage means 46a of the host device 46 is
It is possible to send new MIDI information from the host device 46 to the musical tone information storage medium 42 by sending the I information via the transmitting/receiving means 46b and the transmitting/receiving means 48a on the karaoke apparatus side.

Although the musical tone information for one song shown in Figure 1 above is divided into the prelude section, each chorus section, and the back end section, it is not limited to this method of division, and may be divided into more detailed sections. It is also possible to perform separate classifications.

[Effects of the Invention] As described above, according to the musical sound reproduction device with a shortened reproduction function according to the present invention, it is possible to reproduce musical sounds only for a desired portion of one selected song. That is,
It is possible to construct musical tone information in a shortened form using only the specified range.

By playing back musical tones based on this shortened musical tone information, the musical tones can be shortened as desired by the user without damaging the continuity of the accompaniment music, etc., and the playback time per song can also be reduced. It is possible to shorten the length.
