Abstract

(57) [Summary] [Purpose] The rhythm pattern is determined based on the barcode data read from the barcode, and the rhythm pattern rich in chance is easily created. A barcode BC is read by a barcode scanner 7, and a corresponding one is selected from a plurality of rhythm patterns stored in advance for each rhythm instrument sound based on the numerical data. The third digit "6" from the left corresponds to the bass drum, and the fourth to twelfth digits correspond to the snare drum, low conga, hibongo, rimshot, cymbal, hi-hat, maracas, shaker, and whistle, respectively. When started in the play mode, each instrument sound is output according to the corresponding rhythm pattern. In this way, the selection of the rhythm pattern is made very simple simply by reading the barcode BC.

Description

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 obtaining rhythm pattern performance information based on bar code data obtained by reading a bar code.

[0002]

2. Description of the Related Art Conventionally, the rhythm pattern of an electronic musical instrument is determined by the manufacturer side so that it cannot be changed by the user, like the one attached to an electronic organ, or the It was common to have a huge number of parameters so that the rhythm pattern could be created freely.

[0003]

However, with the one attached to the electronic organ, the rhythm pattern cannot be freely created by the user. On the other hand, with a so-called rhythm machine, it is possible to freely create rhythm patterns, but there is a problem that it is difficult for anyone other than a user who is familiar with some hardware to freely create rhythm patterns.

Further, the procedure for creating the measure is, for example, 1 bar per 1
It is time consuming and not easy, such as dividing into 6 and inputting data one by one so that a sound is emitted at a corresponding timing. There is also a method of storing the information actually played by a so-called real-time recording method instead of a data input method, but in this method, if the performer is a beginner, the rhythm tends to be irregular, and in practical terms There was a problem that you could only make simple rhythm patterns.

Therefore, the present invention uses a bar code medium, which is very widespread today, and determines a rhythm pattern based on the bar code data to facilitate the creation of a rhythm pattern rich in chance. The purpose is to do.

[0006]

In order to achieve the above object, the electronic musical instrument of the present invention stores a plurality of rhythm patterns in advance for each predetermined musical tone of a rhythm system, as shown in FIG. A pattern storage means M1, a bar code reading means M2 capable of reading a bar code, a selection means M3 for selecting a corresponding rhythm pattern for each musical instrument sound from the pattern storage means M1 based on the read bar code data, and a predetermined value. Sound source means M4 for outputting the corresponding musical instrument sound in accordance with the selected rhythm pattern when the pronunciation command is input.

[0007]

According to the electronic musical instrument of the present invention having the above structure,
The pattern storage means M1 stores a plurality of rhythm patterns for each predetermined rhythm-type musical instrument sound in advance, and the selection means M3 selects a pattern based on the barcode data read from the barcode BC by the barcode reading means M2. A corresponding rhythm pattern for each musical instrument sound is selected from the storage means M1. Then, for example, when the start key is pressed, a sound generation command is input, and the sound source means M4 outputs a corresponding rhythm instrument sound according to the selected rhythm pattern.

The selection of the rhythm pattern is made very simple simply by reading the bar code BC of the sundries and the like, and the rhythm pattern rich in chance can be obtained. So, for example, "The gum rhythm is this."
"The rhythm of the pencil case is this," and it has the potential to be enjoyed even by children of a relatively young age group.

EXAMPLE A first example of the present invention will be described below. Figure 2
Shows the appearance of the electronic musical instrument 1 of the present embodiment.
Includes a panel 5, a pen-shaped barcode scanner 7 for reading the barcode BC, a speaker 35, and the like. The panel 5 has operation buttons such as a read button 9, a play button 11, a stop button 13, a save button 15, and a selection button 17 for setting the barcode reading mode, and a volume operator 19 for volume control. It is arranged.

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, ROM 23, and 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. An amplifier 33 that amplifies the output acoustic signal and a speaker 35 that produces a sound are connected to the sound source 31.

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

The ROM 23 previously stores a plurality of rhythm patterns for each predetermined rhythm-type musical instrument sound. In the present embodiment, numbers are assigned to ten types of instrument sounds, mainly bass drum, cymbal instrument sounds, bass drum, snare drum, low conga, hibongo, rim shot, cymbal, hi-hat, maracas, shaker, and whistle. 1 determined by "1" to "9" and "0"
0 kinds of rhythm patterns are stored. An example thereof is shown in FIG.

FIG. 4 shows a rhythm pattern of a bass drum. In this embodiment, a basic rhythm pattern is made to correspond to a smaller number, and the larger the number, the more complicated the rhythm pattern. In this embodiment, the one corresponding to the number "0" is the most complicated rhythm pattern.

The selection of these musical instrument sounds and the setting of the rhythm pattern are not limited to the types described above, and may be appropriately changed depending on the situation. Further, since the number of types is limited to 10 in the above embodiment, it is preferable that the rhythm pattern data itself can be supplied from an external storage device such as a floppy disk.

Next, the operation of this embodiment will be described by taking as an example the case where bar code data is read from a bar code BC using a JAN code (a kind of bar code). J
The AN code is a code that uses a numerical value of 0 to 9,
There are two types of standard codes for digits and reduced codes for eight digits. Here, as shown in FIG. 5, a 13-digit standard code will be described.

The bar code can be read by pressing the read button 9 to enter the bar code reading mode. And
For example, the familiar barcode BC (such as the one printed on the candy packaging) is read by the barcode scanner 7. If the reading is successful, a buzzer (not shown) sounds. When the bar code is not normally read, the bar code reading waiting state continues. Bar code B
If you want to stop reading C, press the read button 9 again.
Press to cancel.

In the case of the standard code of the read bar code data, the left two digits are the country code, and the code attached in Japan is "49" and is constant. Therefore, when determining the control data of each parameter described above, it becomes constant and no change can be obtained in the rhythm pattern.
Data is assigned sequentially from the third digit from the left.

Specifically, the third digit "6" from the left is the bass drum, and the fourth to twelfth digits are the snare drum, low conga, hibongo, rim shot, cymbal, hi-hat, maracas, shaker, and so on. Correspond to each whistle. The 13th digit is used for a spare instrument sound.

Next, when the play button 11 is pressed to enter the performance mode, each musical instrument sound is output from the sound source 31 according to the corresponding rhythm pattern and is output from the speaker 35 via the amplifier 33. Therefore, the performance is performed with different rhythm patterns according to the read bar code BC. To stop playing, press the stop button 13. When the desired performance is completed, the save button 15 is pressed, and then the select button 17 having a number from "1" to "4" is pressed, and the selected number is saved. The performance data of the predetermined rhythm pattern once stored can be selected by pressing the selection button 17 of the corresponding number.

This rhythm pattern selection is made very simple by simply reading the bar code BC, whereby a rhythm pattern rich in chance can be obtained. Therefore,
"Gum rhythm is this" and "pencil box rhythm is this," and unexpected rhythm patterns appear, which may be enjoyable enough for children of a relatively young age group.

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

[0022]

As described above, according to the present invention, a very widespread medium called a barcode is used,
Since a rhythm pattern is selected based on the bar code data and a musical instrument sound is played according to the selected rhythm pattern, it is possible to easily create a rhythm pattern rich in chance.
