DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic musical instrument capable of determining a performance pattern of an automatic performance based on bar code data obtained by reading a bar code and obtaining an automatic performance rich in chance.

[0002]

2. Description of the Related Art Conventionally, automatic performance of an electronic musical instrument has been determined on the maker side such as a so-called automatic performance piano so that the user cannot change it, or conversely, the user inputs performance information and freely creates the performance. Performance information storage devices such as sequencers that can be used have been common.

[0003]

However, in the case where the maker determines the performance, such as an automatic performance piano, the performance pattern creation is not permitted to the user at all. On the other hand, with a sequencer, it is difficult for anyone other than those who are familiar with some hardware to enter the performance information freely, and since the user has to enter the performance information in detail one by one, considerable time is required to create the performance information. There was also the problem of spending time.

Accordingly, the present invention determines a performance pattern based on bar code data read from a bar code,
The purpose of the present invention is to make it easy to perform an automatic performance rich in chance.

[0005]

In order to achieve the above object, an electronic musical instrument according to the present invention, as shown in FIG. 1, divides a music piece into a plurality of parts along the flow of performance and corresponds to each part. The performance pattern storage means M1 for storing a plurality of performance patterns in advance, the barcode reading means M2 capable of reading barcodes, and the performance pattern storage means M1 based on the read barcode data. Selection means M3 for selecting a corresponding performance pattern for the part
And automatic performance means M4 for automatically performing each of the parts in accordance with the selected performance pattern while following the flow of the performance when a predetermined performance command is input.

The above-mentioned tune is divided into a plurality of parts along the flow of the performance, for example, a prelude (intro), a first chorus, an interlude, a second chorus, and a ending (ending). No. Alternatively, the music piece may be divided into predetermined measures along the flow of the music. How to set these parts may be appropriately changed according to the situation.

[0007]

According to the electronic musical instrument of the present invention having the above configuration,
The performance pattern storage means M1 stores a plurality of performance patterns in advance corresponding to each of a plurality of parts obtained by dividing the music into a plurality of parts along the flow of the performance, and the barcode reading means M2 reads the plurality of performance patterns from the barcode BC. Based on the read barcode data, the selection means M3 selects a corresponding performance pattern for each part from the performance pattern storage means M1.

Then, for example, when a play button or the like is pressed, a performance command is input, and the automatic performance means M4 outputs
While performing along the flow of the performance, the automatic performance of each part is performed according to the selected performance pattern. The selection of the performance pattern can be made very simply by simply reading the barcode BC of generally sold miscellaneous goods. Therefore, for example, "the playing of the gum is this" and the "playing of the pencil case is this", there is a possibility that children of relatively young age can fully enjoy it.

[0009]

Next, a first embodiment of the present invention will be described. FIG.
1 shows the external appearance of the electronic musical instrument 1 of the present embodiment.
Is provided with a panel 5, a pen-shaped bar code scanner 7 for reading a bar code BC, a speaker 35, and the like. The panel 5 has operation buttons such as a read button 9 for setting a barcode reading mode, a play button 11, a stop button 13, a save button 15, and a music selection button 17, and a volume operator 19 for volume control. Are located.

FIG. 3 shows a block diagram of a signal processing system of the electronic musical instrument 1. As shown in the figure, the electronic musical instrument 1 is configured as a microcomputer including a well-known CPU 21, a ROM 23, and a RAM 25.
The OM 23 and the RAM 25 are mutually connected to the barcode scanner 7, the panel 5, and the sound source 31 via the bus line 27. The sound source 31 is connected to an amplifier 33 for amplifying an output audio signal and a speaker 35 for generating sound.

The above-described bar code scanner 7 forms an image of reflected light from the bar code BC on an image sensor (not shown), takes in an electric signal corresponding to the formed information image, amplifies it, and binarizes it. It is a well-known method that performs processing and decoding to decode barcode data.

In the ROM 23, a plurality of performance patterns are stored in advance corresponding to each of a plurality of parts obtained by dividing a tune along a performance flow. First,
The part will be described. In general, there is a common song in popular music. Specifically, an example is shown: Intro → No. 1 A of the song → No. 1 B → No. 1 so-called chorus → No. 2 A → No. 2 B → No. 2 chorus → Interlude → No. 2 chorus → It's like ending.

In this embodiment, a music piece is divided into these ten types of parts, and a plurality of performance patterns are stored for each part. Next, the performance pattern will be described.
Generally, in the case of the above-described ten types of part division, one part generally has a length of eight measures. In the present embodiment, for example, enka 1
The performance pattern of each music genre is set in advance in such a manner as enka 2, rock 1, rock 2. More specifically, the intro pattern of Rock 1 is characterized by intense drum performance, and the interlude pattern of Rock 2 is characterized by electric guitar performance. Also, the intro pattern of Enka 1 is characteristic of a shakuhachi tone, and the interlude pattern of Enka 2 is characteristic of shamisen performance.

In addition, how to set these performance patterns,
That is, the way of setting the genre may be set in any manner. Further, in the above-mentioned embodiment, the number of genres is limited to ten, so that the performance pattern data itself can be supplied from an external storage device such as a floppy disk. Good.

Next, the operation of the first embodiment will be described by taking as an example a case where bar code data is read from a bar code BC using a JAN code (a type of bar code).
The JAN code is a code using numerical values of 0 to 9 and is 1
There are two types: a standard code of three digits and a reduced code of eight digits. Here, as shown in FIG. 4, the description will be made using a 13-digit standard code.

The bar code can be read by pressing the read button 9 to set the bar code reading mode. And
For example, a familiar barcode BC (such as one printed on a candy package) is read by the barcode scanner 7. If the reading is performed normally, a buzzer (not shown) sounds. If the reading is not performed normally, the bar code reading standby state is kept. In addition, bar code B
If you want to stop reading C, press the read button 9 again.
Press to cancel.

In the case of the read bar code data, in the case of a standard code, the left two digits are a country code, and the number added in Japan is "49", which is constant. Therefore, when the above-mentioned performance pattern is determined, for example, the intro is always constant and no change is obtained.
Assign sequentially from the digit data.

Specifically, the first digit from "6" in the third digit from the left is 1
The ten parts from the intro to the ending described above are sequentially assigned to ten pieces of numerical data up to “8” in the second digit, and for each part, the corresponding performance pattern (enka 1, rock 2, etc.) Select The 13th digit is used for a spare part.

In this way, the performance pattern of each part is determined. For example, the intro is a pattern of rock 2, the next No. 1A is a pattern of Enka 1 and the first No. B is a pattern of Kayo 2 Next, when the play button 11 is pressed, the performance mode is set, and the automatic performance starts with the performance pattern described above. When the performance is stopped, the stop button 13 is pressed. When a favorite song is completed, the user presses the save button 15 and subsequently presses the song selection button 17 having a number from "1" to "4", and the song is saved corresponding to the song selection number. The music data once saved can be selected by pressing the music selection button 17 of the corresponding number.

The selection of the performance pattern can be made very simply by simply reading the bar code BC, whereby a performance with a high chance is obtained. Therefore, unexpected performances can be obtained, such as "Gum performance starts with rock and ends with enka." Or "Pencil case starts with nursery rhymes and ends with reggae."

Although one embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and various embodiments can be adopted without departing from the gist of the present invention.

[0022]

As described above, according to the present invention, a bar code, which is very widely used today, is used.
Since a performance pattern is selected based on the barcode data and an automatic performance is performed according to the selected performance pattern, it is possible to easily perform a performance rich in chance.
