Description

  The present invention relates to an electronic musical instrument or a computer that uses a MIDI signal, and an LED (light emitting diode).

  Conventionally, MIDI (electronic musical instrument digital interface) conforming to the JIS standard is a standard for exchanging music performance information in an electronic musical instrument.

  The MIDI function is to control electronic musical instruments, sound devices, computers, etc. that receive MIDI signals from MIDI controllers and computers that emit MIDI signals. In the multimedia field such as live performances, music recording, video production, etc. It's being used.

  In addition to simply energizing the LED, the LED lighting control method can control complex lighting patterns by using a lighting control program. When multiple LEDs are used, lighting, characters, pictures, and animations are displayed. Can be expressed.

  Since the LED can emit light strongly by itself, the expression by lighting is easily visible from a distance, and is used as various information transmission devices such as an electric bulletin board.

  In addition, the following nonpatent literature 1 can be mentioned as a well-known technique relevant to this invention.

  "Japan Standards Association Standard No. JIS X 6054-1: 1999" Electronic Musical Instrument Digital Interface (MIDI)

  When a musician performs a live performance, a device using computer software is required for the player to instantly send character information and animation to the audience, and for the character information to be exchanged between performers. On the monitor screen, the amount of light is small, and the expression is poor in visibility especially from a distance.

  In order to control LED lighting with good visibility from a distance and express it as a character, picture, or animation combined with music, a technique relating to a lighting control program is necessary, and it is difficult to realize for those who do not have electrical engineering knowledge.

  The present invention has been made in view of these points, and its purpose is to control the lighting of the LED by a MIDI signal used by a musician in an electronic musical instrument, thereby lighting the LED collective screen and attaching it to the performer. It is to contribute to the performance of music performance as an LED accessory.

  The MIDI LED lighting control device of the present invention that achieves the above-mentioned object has a converter that displays characters, pictures, animations, etc. on the LED collective screen by a MIDI signal, and also has an LED collective screen that controls the lighting by the converter. It is characterized by that.

As described above, according to the present invention, when a music performance using MIDI is performed, the performer instantly emits an animation synchronized with the tempo of the music, character information to the audience, or the music score and character information between the performers. It can be exchanged and shared.
Since the LED is used, the visibility is good even in a dark performance hall, and it is extremely effective for obtaining a gorgeous performance for the audience.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  1 to 4 relate to a first embodiment of the present invention, FIG. 1 is a front perspective view of the appearance, FIG. 2 is a rear perspective view of the appearance, FIG. 3 is a plan view thereof, and FIG. It is a flowchart until it reaches screen lighting.

  As shown in FIGS. 1 to 3, the LED lighting control device 11 using MIDI is provided with an LED aggregate screen 13 in which LEDs are aligned on the outer surface of a box-shaped structure 12 made of iron, plastic, or the like. And the converter 16 that controls the lighting of the LED collective screen 13 is built in the box-shaped structure 12.

  As shown in FIGS. 2 and 3, a household power input terminal 14 and a MIDI signal input terminal 15 are provided on the rear surface of the box structure 12, and are connected to a converter 16 built in the box structure 12. Is done.

As shown in FIG. 4, the MIDI signal input terminal 15 is a terminal for connecting a MIDI cable conforming to the MIDI standard, and the shape of the terminal conforms to the MIDI standard.
A MIDI controller or a computer that emits a MIDI signal is connected to the MIDI signal input terminal 15 with a MIDI cable, and the MIDI signal is received.

  As shown in FIG. 4, the converter 16 inputs household power from the household power input terminal 14, and converts the MIDI signal input from the MIDI signal input terminal 15 to a lighting signal that controls lighting of the LED collective screen 13. It has an electric circuit and software to convert.

  The software included in the converter 16 refers to a MIDI signal input from the MIDI signal input terminal 15, that is, music information (pitch, size, length, timbre effect, etc.) to light up the LED collective screen 13 to display characters, It is a program that has the function of controlling pictures and animation.

  The box-shaped structure 12 has a rectangular parallelepiped shape having dimensions of W430 mm × H300 mm × D50 mm, for example, and is standardized as a suitable size when mounted on a commercial 19-inch rack (standard number JIS C 6010-1: 1998). To do. This facilitates design and installation.

  The LED arrangement method on the LED collective screen 13 is, for example, a total of 2,048 rectangular screens in which 16 vertical x 128 horizontal are aligned on the same plane. As a result, a maximum of 2,048 notes (128 notes × 16 channels per channel) of the note information that can be handled simultaneously per MIDI cable and LEDs are combined in pairs to help create characters, pictures, and animations.

  While the embodiments and examples of the present invention have been described above, the scope of the present invention is not limited to this. For example, the size and the material of the box-shaped structure are arbitrarily selected without being limited to the box shape according to the use of the LED lighting control device according to the present MIDI.

  Further, the LED arrangement method on the LED collective screen is not limited to the arrangement method described in the embodiment, and the number of LEDs to be arranged and the LED arrangement shape can be arbitrarily selected. Further, the size, emission color, and brightness of the LED can be arbitrarily selected.

  The power source supplied to the converter is not limited to a household power source, and a dry battery or a rechargeable battery can also be used.

  The installation location of the converter is not limited to the inside of the box-type structure, and can be used by being removed outside. Since the LED collective screen is independently reduced in weight, it is effective in improving the installable range and portability.

  The present invention can be used in the industrial field of manufacturing and selling electronic musical instruments.
