Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic performance device for sequentially reproducing a plurality of music data corresponding to a plurality of music pieces and automatically playing the music data, for example, a chime or music for notifying the predetermined time. The present invention relates to an automatic performance device for generating a sound from a speaker, and more specifically, to an automatic performance device that prevents monotonousness by sequentially playing music with different tempos, for example.

[0002]

2. Description of the Related Art It is widely practiced to play a chime or music at a predetermined time to notify that the predetermined time has been reached. As a device for playing music when the predetermined time is reached, an automatic performance device that stores music data corresponding to one or a plurality of predetermined songs and automatically plays a predetermined song based on the music data It is conceivable that the automatic performance device is combined with a program timer for instructing the start and end of the automatic performance when a predetermined time is reached.

Here, the program timer only sets the start and end of the automatic performance, and the selection of the musical piece to be played is left to the automatic performance device side.

[0004]

When only one piece of music is repeatedly played when selecting the piece of music, when there is a time during which many pieces of music can be played between the start time and the end time of the automatic performance. , Becomes extremely monotonous.
It is also conceivable to use an automatic performance device having a random performance mode in which the automatic performance device randomly selects and plays from among a large number of songs corresponding to a large number of stored music data. However, even in this case, for example, only songs with a fast tempo continue and songs of many genres (classical, folk songs, image music, popular, enka, song, etc.) are stored, but songs of the same genre However, there is a problem that there is still some dissatisfaction with performing a variety of automatic performances.

There is also a problem in that it is very troublesome for a human to set the music to be played. SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems and to provide an automatic performance device capable of performing a wide variety of automatic performances without requiring any special labor.

[0006]

The present invention solves the above-mentioned problems and is applied to an automatic performance device for automatically reproducing a plurality of recorded music data corresponding to a plurality of music pieces in sequence. And adopted the following technical means. That is, (1) a classifying unit that classifies the songs of the music data into a plurality of groups based on a predetermined standard, and (2) randomly selects songs from the songs belonging to each group and circulates the songs belonging to different groups. And a means for selectively selecting a musical piece.

Here, for example, the tempo of a piece of music is selected as the predetermined criterion.

[0008]

Since the present invention is configured as described above, by appropriately setting the predetermined criteria for classification, it is possible to play music of various contents, not monotonous, for a long time in response to the listener's request. You can

[0009]

FIG. 1 shows an embodiment of the present invention. FIG. 1 is a block diagram showing the configuration, including setting means 1, automatic performance means 2, timer 3, control means 4 having a CPU, and display means 5.
The control means 4 is provided with a storage means inside, and operates the automatic musical instrument according to an operation program stored in the storage means.

The timer 3 is a so-called clock that counts time, and the display means 5 displays a set program and time. The setting means 1 has an operation function of setting a program and time. The automatic performance means 2 automatically performs according to the music data input from the control means 4, the output thereof is converted into an analog signal, and is output as a musical sound from a speaker via, for example, an amplifier.

The timer 3 is configured to be programmable, and operates the setting means 1 to set the performance contents (chime, music, etc.), performance start time, performance end time, etc. while confirming them on the display means 5. By setting, the predetermined contents are automatically played according to the program. As shown in FIG. 3, the feature of the present embodiment is that if each song is classified according to genre (classical, folk song, image music, etc.), it is further classified into three according to the tempo, and the genre of the song is designated. , Music of a specified genre is played, but each time the music changes, among the three groups classified by tempo, one music in each group is cyclically played,
Moreover, it is programmed so that one piece is randomly picked up from a large number of pieces belonging to each group and played.

That is, when the genre of music to be played is designated, first, one song is randomly selected from the slow tempo group in the genre and played. Next, one song from the middle tempo group in the genre is randomly selected and played, and then one song from the first tempo group in the genre is randomly selected and played, and this is repeated. It is a thing.

A flowchart showing the performance sequence of this embodiment will be described with reference to FIG. FIG. 2 shows the headers of the stored music data. Each header has a music title,
The genre, tempo information, performance data address, etc. are stored. When the power of this automatic performance device is turned on,
An initial program (not shown) is activated, and the initial program causes the RO in the automatic musical instrument to operate.
The data stored in the header of each music data stored in M (see FIG. 2) and, if a memory such as a ROM card has been added to this automatic performance device, each music stored in the expansion memory The data stored in each header portion of the data is referred to, the tempo information is determined for each genre, and as shown in FIG.
It is classified into a middle tempo group and a first tempo group and stored in the storage means in the control means 4. After that, when a music genre to be played is designated and a random playing mode of music is designated, performance processing is performed according to the flowchart of FIG.

(Step 1) S1 register F is set to 0
Set to (slow tempo). (Step 2) The value of the S2 register F is judged. (Step 3) S3 A memory to be read is selected according to the value F determined in S2. (Step 4) S4 The number N of pieces of music stored in the selected memory is stored in the register.

(Step 5) S5 One numerical value is randomly selected from the number N of pieces of music by using a random function, and the numerical value is stored in the register A. (Step 6) The automatic performance means is instructed to start playing the music corresponding to the numerical value stored in the S6 register A. (Step 7) S7: It is judged whether or not there is a performance end command generated by an operation using the operation function of the setting means or when the performance end time comes. If there is a performance end command, the process jumps to S12.

(Step 8) S8 It is judged whether or not the music currently being played has ended. If not completed, the process returns to S7. (Step 9) Increment the value of S9 F. (Step 10) If the value of S10 F becomes 3, S
11. If it is 0 to 2, jump to S2.

(Step 11) The value of S11 F is set to 0, and the process jumps to S2. (Step 12) S12 The automatic performance ends. By executing the program shown in FIG. 4, the music randomly picked out from each of the three groups classified according to the tempo is cyclically played one by one over each of the three groups.

In the present embodiment, the classification standard is the tempo of performance data, but the present invention is not limited to this, and other elements of music, for example, genres, are set as classification standards, and a large number of genres are set. A wide variety of music may be automatically played by straddling and playing sequentially.

[0019]

As described above, according to the present invention, since it is possible to continuously and automatically play a variety of music, it is possible to play the optimum music according to the TPO, the monotony is prevented, and the mood of the listener changes. Can relax the listener, and can be expected to have excellent effects on mental health.
