Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic music reproducing device that converts musical tone information stored as digital information into an electronic music signal and reproduces and outputs the same.

[Prior Art] In recent years, in musical sound reproduction devices such as karaoke machines, in order to cope with the miniaturization of the devices and the increase in the amount of recorded musical sound information, electronic music playback devices that have a built-in storage medium for storing digital musical sound information have been developed. Playback devices are now being used. Musical sound information stored as such digital signals includes MID, which is information indicating timbre, pitch, volume, etc.
I (MusicaInstruIIlent D
(digital interface) information is known. This is interface information for digitally communicating performance information of each musical instrument, and is created based on international standards (note that "MIDIJ" is a registered trademark).

Such MIDI information is then played back by a music playback device such as a synthesizer.

According to such an electronic music playback device that uses digital musical tone information, there is no problem of the number of disks gradually increasing when increasing the amount of information, unlike laser disk type karaoke devices. This has the advantage that musical tone information can be easily added to or changed on the medium.

When such an electronic music playback device is used as a commercial karaoke device, there is a time when the device is not being used as a karaoke device, that is, a time when no one is singing and no accompaniment sound is being played. In such a case,
It is necessary to play background music to create an atmosphere in the store. Usually, as a means of broadcasting such GM, cable broadcasting is used or music is reproduced and output using another music software.

[Problems to be Solved by the Invention] However, as in the above-mentioned conventional art, during times when the electronic music playback device is not used as a karaoke device,
When broadcasting BGM, there is a problem in that cable broadcasting requires a fee and maintenance costs are required in addition to the karaoke equipment. Also,
When playing BGM using other music software, a separate device from the karaoke device is required, which requires installation and maintenance costs. Furthermore, installation space is also required, which is contrary to the goal of saving space.

Therefore, it is conceivable to reproduce musical tone information in an electronic music reproduction device (such as a karaoke device) and change it to BGM. However, in the case of karaoke equipment, the performance sound played is accompaniment sound for singing, and is inappropriate as BGM, and playing it for purposes other than singing may actually disturb the user. there were.

Purpose of the Invention The present invention was made with the aim of solving the above-mentioned problems, and its purpose is to reproduce each piece of music using only the musical tone information of an electronic music reproduction device, without using two media. An object of the present invention is to provide an electronic music reproducing device capable of reproducing good music for karaoke accompaniment and as BGM.

[Means for Solving the Problems] In order to achieve the above object, the electronic music playback device according to the present invention converts the digital musical sound information sound of each song specified by the input means into electronic music information by the music playback means. In an electronic music playback device that converts the data and outputs audio from a speaker, a musical tone information storage means separately stores each performance data of a main melody part which is a singing part and other parts as digital musical tone information for each song, and a specified musical tone information storage means. a control unit that reads music performance data from the musical tone information storage unit and sends it to the music playback unit; and a control unit that is installed in the input unit and instructs to set the music playback method of the device to either karaoke playback or BGM playback. a reproduction method instruction means for;
A program storage means storing an operation program of the control section, the program storing means storing an operation program of the control section, when a karaoke playback method is specified by the playback method instruction means, the main melody part of the performance data of the read playback music is selected more than other parts. A program storage means having a program that causes the control unit to operate the control unit to set a low volume and, when a BGM reproduction method is specified, set other parts to a volume equal to or lower than that of the main melody part and send it to the music reproduction means. It is characterized by including.

[Operation] In general, when a musical sound reproduction device operates as a karaoke device, it is preferable that the volume of the main melody part, which is the part sung by the singer, is lower than the performance sounds of the other parts. That is, if the main melody part is deleted, it will be difficult for general users to sing, and conversely, if the volume of the main melody part is increased, it will no longer sound like a melodious sound, so the main melody part is made small. Furthermore, when playing BGM, it is necessary to set the volume at a level that does not interfere with people's conversations, and it is preferable that the main melody part has a volume equal to or higher than that of the other parts.

The present invention has been made in consideration of the relationship between karaoke playback and BGM playback, and according to the present invention, the musical sound information storage means stores each performance of the main melody part, which is the singing part, and the other parts. The data is stored separately as digital musical tone information.

Then, the control unit reads the musical tone information of each song and supplies it to the music reproduction means, and here, the reproduction method instruction means instructs either karaoke or BGM.

When this instruction is given, the control section sends the main melody part and other parts to the music reproduction means as performance data at a volume that matches the instructed reproduction method, based on the operation program in the program storage means. In other words, when the karaoke playback method is specified, the volume of the main melody part is lower than that of other parts, and when the BGM playback method is specified, the volume of the other parts is set to be the same as or lower than the main melody part. to the music playback means.

Thereby, two types of reproduction can be performed, one suitable for karaoke accompaniment and the other suitable for BGM, based on one piece of performance data for each piece of music stored in the musical tone information storage means.

[Example] Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing a configuration when an electronic music playback device according to the present invention is used as a karaoke device. In the figure, input means 10 for instructing music selection, playback and stop, etc. is provided with playback method instructing means 12, which is a characteristic component of the present invention. The reproduction method instruction means 12 is formed by installing respective keys for instructing, for example, a karaoke reproduction method and a BGM reproduction method.

The input means 10 is connected to a control section 14, and the control section 14 controls the operation of each part of the apparatus based on operation signals from the human power means]O.

A program storage means 16 is connected to the control section 14, and an operation program for the control section 14 is stored in the program storage means 16. That is, the control section 14 performs control operations according to the operation program stored in the program storage means]6.

Further, musical tone information storage means 18 is connected to the control section 14 . The musical tone information storage means 18 stores musical tone data of a large number of musical pieces, and performance data of each performance part is stored separately for each musical piece.

FIG. 2 shows part of the MIDI performance data of a certain part of one of the stored musical tone data. In this data, N, PROG:CHGJ indicates the setting of the instrument that produces the reproduced sound of this part, and number 20 shown in the figure indicates, for example, a piano. Next, r
2. CRT: CHGJ is for setting the control of MIDI data, and the displayed C11 means the master volume setting among the control settings, and if you enter a value in the X of the rDYNJ part on the right side,
This becomes the master volume setting value. This master volume sets the overall volume of this part.

Next, r3. The display G/MINERJ indicates the key of this song. Furthermore, r4.4/4 indicates the time signature of this song.

The numbers 5 and below indicate the pitch of each reproduced sound, rsTJ indicates the length of the sound, and rGTJ indicates the pitch of each reproduced sound.
This is the gate time for actually keeping the sound generation state on. In other words, the gate time GT is set to be shorter than the standard time ST to prevent the sounds from overlapping, since the generated sound continues to linger even after the sound generation is turned off. "C7" indicated in each pitch data column indicates the volume for each pitch, that is, for each single note, and the number 8 to the right of it indicates the volume for each pitch, that is, for each single note.
0 is the numerical value that sets the volume.

As a result, the X set to master volume C11
The product of this and the volume value of each note becomes the volume of each note.

In this embodiment, the value of rcll XJ is not set, and the value of X for each part is determined according to the playback method set by the playback method instruction means 12.

Next, a synthesizer 20 as a music playback device is connected to the control unit 14, and the synthesizer 20 further includes:
It is connected to a speaker 24 via a mixing amplifier 22. The musical tone data read by the control section 14 is input to the synthesizer 20, and an electronic music signal converted based on the musical tone data is reproduced and outputted from the speaker 24 via the mixing amplifier 22.

A microphone 26 is connected to the mixing amplifier 22, and the singer's voice is inputted from the microphone 26, synthesized and amplified together with the accompaniment sound, and reproduced from the speaker 24.

In this karaoke apparatus, a video playback device 28 and a monitor 30 are connected to the control unit 14, and the background image and lyrics information corresponding to the accompaniment sound are displayed on the monitor 30.

Next, the characteristic operation of this embodiment will be explained based on the flowchart of FIG.

The flowchart in FIG. 3 is a flowchart showing the operation related to the setting of the reproduction method, which is a characteristic feature of the present invention.

First, this operation starts with the designation of a song, and in step (hereinafter referred to as "S") 1, it is determined by the reproduction method instruction means 12 whether the karaoke reproduction method is instructed. Here, if the karaoke reproduction method is instructed (YES), the volume of each part of the musical sound data of the song is set in S2 and S3.

That is, in S2, the volume of the singing heart, which is the main melody part, is set to be low, and in S3, the volume of the other parts is set to be louder than the singing part.

This volume setting is performed by setting the numerical value X of the master volume r C1, 1, J in the data shown in FIG. 2 above. For example, the master volume of the singing part is set to 70, and the master volumes of the other parts are set to 100. This completes the volume setting of 82 and S3.

Next, in S4, a reproduction operation is performed using the master volume set above. That is, the control section 14 supplies predetermined master volume information for each part for karaoke playback to the synthesizer 20 together with the performance data, and the playback operation is performed based on the information.

Next, in S5, it is determined whether or not the karaoke playback has ended, and if it has not ended (No), the playback operation continues, and if it has ended (YES), the next song is reserved in S6. It is determined whether the and,
If it is not reserved (NO), the playback operation ends (S7). And the next song is reserved (YES
), the process returns to Sl again and the following step operations are performed.

On the other hand, in SL, it is not a karaoke playback method (No)
If it is determined that this is the case, it is determined in S8 whether or not the BGM reproduction method is used. Here, it is not a BGM playback method (NO)
In this case, it is determined that no playback method instruction has been given, and S
7 is the playback end operation. And in S8 BGM
If it is determined that the playback method is selected (YES), the volume setting for 80M playback is performed in S9 and 31.0.

That is, in S9, the volume of the singing part is set low,
The volume is set to a low volume similar to that in S2 above.

Then, in S10, the other parts are set to the same or lower volume as the singing part. For example, set the master volume C1,1 of the singing part to 70 or 60.
and set the master volume of other parts to C11.
This is done by setting the value to 50.

In this way, in the BGM reproduction method, the volume of the singing part is set to be the same or lower than that of other parts, but in this embodiment, the volume itself of the singing part is also set to be the same as or lower than that in the karaoke reproduction method. It is set small. In the case of BGM, it is desirable to play it at a relatively low volume so as not to interfere with the user's conversation, so it is possible to keep the volume setting of the mixing amplifier when playing karaoke and play the GM quietly. This is to set the overall volume to a low level so that the music can be streamed.

When the volume setting for the part is completed, a playback operation is performed at the set volume in S11. and,
It is determined in 812 whether or not the BGM playback has ended, and if it has not ended (No), the playback operation S],
1 is continued. Then, BGM playback ended (YE
In the case of S), it is determined in S6 whether there is a reservation for the next song, and similarly to the case of ending the karaoke playback described above, the playback ends in S7 or the step operation from Sl is performed.

As described above, according to this embodiment, the volume of each part suitable for karaoke accompaniment playback and BGM playback can be adjusted in various ways, and two types of music can be played back with one electronic music playback device. can.

Furthermore, by adjusting the master volume C1l of each part in various ways, it is possible to perform various uses such as completely erasing the main melody during karaoke playback, or emphasizing the main melody during BGM playback. can.

[Effects of the Invention] As explained above, according to the present invention, based on musical tone information, which is one medium stored in an electronic music reproduction device, it is possible to reproduce not only accompaniment sounds for singing but also suitable for BGM. It is possible to arbitrarily and selectively play back music, and it is possible to diversify the use of the electronic music playback device.
