The computer according to the embodiment of the present invention for achieving the above-described technical problem is a display unit, a MIDI interface for receiving a MIDI signal, and reads the MIDI signal and if the MIDI signal is a control signal to control the computer according to the control signal and And a controller for controlling the computer according to the music signal if the MIDI signal is a music signal.

The display unit may display a score, a menu, and a virtual keyboard.

The control signal may include a movement control signal and a selection control signal.

The menu may include at least one of a play start, a stop, a file call, a right hand, a left hand, a semitone, a command, a measure number of measures from a measure, a practice speed adjustment, a lesson method, a sound control, and a sound off.

The MIDI signal may be received from a MIDI instrument.

The midi musical instrument includes a digital piano, wherein each key of the digital piano generates the control signal.

As described above, according to the present invention, there is an effect that a user can control a computer using a midi instrument without using a keyboard or a mouse connected to the computer. This has the effect of providing an environment in which the user can control the computer with the midi instrument by using the midi instrument.

Advantages and features of the present invention and methods for achieving them will be apparent with reference to the embodiments described below in detail with the accompanying drawings.

However, it is to be understood that the present invention is not limited to the disclosed embodiments, but may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. It is intended that the disclosure of the present invention be limited only by the terms of the appended claims.

Also, the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. In the present specification, the singular form includes plural forms unless otherwise specified in the specification. As used herein, "comprises" and / or "comprising" does not exclude the presence or addition of components other than the mentioned components. Unless otherwise defined, all terms (including technical and scientific terms) used in the present specification may be used in a sense that can be commonly understood by those skilled in the art.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings in order to describe the present invention in more detail. Like reference numerals refer to like elements throughout.

1 shows an embodiment of a computer according to the invention.

Referring to FIG. 1, the present invention relates to a computer 1 that controls a MIDI signal. The computer 1 according to the present invention includes a MIDI interface 10, a controller 20, and a display unit 30.

The MIDI interface 10 receives a MIDI signal from an external MIDI instrument, reads the received MIDI signal, and transmits the read MIDI signal to the controller 20. In this case, the MIDI signal includes a control signal and a music signal. The control signal is an event (for example, a cursor) displayed on the display unit 30 of the computer 1 using a mouse or a keyboard connected to the computer. This is a signal controlled by the MIDI instrument, and the music signal is a signal representing the performance of the MIDI instrument as music.

The control signal includes a movement control signal for movement of an event and a selection control signal for selecting or releasing the event when the event is in a specific menu from the menu displayed on the display unit 30.

The control unit 20 is a part that controls the computer 1 as a whole. In particular, the controller 20 receives the MIDI signal read from the MIDI interface 10, and controls the computer 1 according to the control signal if the MIDI signal is a control signal, and if the MIDI signal is a music signal, the computer according to the music signal. Control (1).

That is, if the MIDI signal is a control signal, the control unit 20 moves an event or selects a specific menu according to the control signal. If the MIDI signal is a music signal, the controller 20 displays the performance of the MIDI instrument as music through a speaker or the like.

For example, if the MIDI signal is a control signal, the control unit 20 moves the event displayed on the display unit 30, or when the movement of the event is stopped, the computer 20 may select a specific menu. To control 1).

The display unit 30 is a part which shows the operation of the computer 1 or the execution of a program so that the user can see it. For example, the display unit 30 may display the score 310, the menu 320, the virtual keyboard 330, or the like.

In addition, the menu 320 may include at least one of a play start, a stop, a file call, a right hand, a left hand, a semitone, a command, a node repeat count, a practice speed adjustment, a lesson method, a sound control, and a sound off. have.

2A to 2E illustrate an example of controlling a computer according to the present invention with a MIDI signal.

Hereinafter, a description will be given with reference to FIGS. 2A to 2E.

FIG. 2A is an example of the music display shown in the display unit 30 when a specific music software is executed in the computer 1 according to the present invention. The display unit 30 displays the music score 310, the menu 320, and the virtual keyboard 330. do. Here, the menu 320 is composed of play start, stop, file recall, right hand, left hand, semitone, commandment, measure from node to repeat, practice speed adjustment, lesson method, sound control, sound mute.

In this case, each item constituting the menu may be selected using a keyboard or a mouse (not shown) connected to the computer 1.

2B illustrates a digital piano 100 as an example of a midi instrument. Each keyboard of the digital piano 100 generates a MIDI signal, and each keyboard may generate both a control signal and a music signal as MIDI signals. Here, the three right keys 110, 120, and 130 of the digital piano 100 are set to the event left movement control signal generation keyboard 110, the event right movement control signal generation keyboard 120, and the selection control signal generation keyboard 130. It is possible. However, it should be noted that the control signal generated by each key can be variously set depending on the setting.

2C illustrates an example of selecting a menu with a specific key.

If the menu 320 and the event 340 displayed on the display unit 30 are the same as (a), when the user presses the event left movement control signal generation keyboard 110 of the MIDI instrument 100, the MIDI instrument 100 Generates a MIDI signal containing the control signal and transmits it to the computer 1. When the MIDI interface 10 of the computer 1 receives and reads a MIDI signal including a control signal, and transmits the read control signal to the control unit 20, the control unit 20 generates an event 340 according to the control signal. Move to the left. At this time, the display unit 30 displays (b).

Subsequently, when the menu 320 and the event 340 displayed on the display unit 30 are the same as (b), when the user further presses the event left movement control signal generation keyboard 110 of the MIDI instrument 100, As shown in the procedure, the control unit 20 controls the display unit 30 to display (C).

2D to 2E illustrate an example of controlling a computer when a user selects a file to be loaded from the menu 320 by using a MIDI instrument.

2D to 2E, when the user selects a file to be loaded from the menu 320 by using a MIDI instrument, the display unit 30 selects a song that can be selected according to each virtual keyboard 330 as shown in FIG. 2D. Display. This allows each key of the digital piano 100, which is a MIDI instrument, to generate a control signal. For example, when a user attempts to select "Arirang", the user presses a specific key 140 set to select "Arirang" and selects "Arirang". The computer 1 allows the user to play "Arirang" or to practice the keyboard. That is, the control unit 20 of the computer 1 controls the accompaniment to come out through the speaker, and the display unit 30 displays the Arirang sheet music and the virtual keyboard according to each sheet music.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, It will be appreciated that one embodiment is possible. Accordingly, the true scope of the present invention should be determined by the technical idea of the claims.
