The information extraction unit 120 extracts information about a note or velocity from the MIDI sound source input from the sound source input unit 121. Here, the notes refer to each single note constituting a MIDI sound source, and the MIDI sound source is composed of a number of notes. Velocity is information about the speed at which a key corresponding to a note is pressed. Also, the sound source input unit 121 may be an input means such as a USB terminal through which an administrator can input a MIDI sound source from the outside, or a digital musical instrument such as a digital keyboard capable of generating a MIDI sound source by a player's manipulation.

That is, the information extraction unit 120 extracts the number of notes constituting the MIDI sound source, the playing time of the note, the length of the note, and the velocity of the corresponding note. Here, the information extraction unit 120 provides information on the extracted note or velocity to the control signal generation unit 130. The control signal generation unit 130 is based on the information on the notes or velocity of the MIDI sound source extracted from the information extraction unit 120 so that the operation of the moving lighting unit 110 can be controlled according to the MIDI sound source.

On the other hand, when one moving lighting unit 110 is provided in the moving lighting system 100, the control signal generation unit 130 moves the moving with a preset operation pattern for the note value of the MIDI sound source included in the score data. The flow data may be generated by generating a control signal for operating the lighting unit 110.

For example, as an operation pattern, the E3 note (E3 note) is a function of the channel 12 (Ch12: Blue from dark to bright) of the moving light unit 110, that is, the value of the blue light output and the blue light brightness (Value) ), G3 note (G3 note) is the function of the channel 12 of the moving light unit 110 (Ch12: Blue from dark to bright) (Function), that is, the value of the blue light output and blue light brightness (Value) When set, the control signal generation unit 130, when the E3 note (E3 note) is displayed in the score data, the moving light unit 110, the control signal to output a blue light at a brightness corresponding to the velocity value of the note When the G3 note is displayed in the score data, a control signal is generated to output a blue light at a brightness corresponding to the velocity value of the note, thereby generating flow data.

As another example, as an operation pattern, the E3 note (E3 note) is a function of the channel 12 (Ch12: Blue from dark to bright) of the moving light unit 110, that is, the value of the blue light output and the blue light brightness ( Value), G3 note (G3 note) is the function of the channel 13 (Ch13: White from dark to bright) of the moving light unit 110 (Function), that is, the value of white light output and white light brightness (Value) When set to, the control signal generating unit 130 controls to display the blue light at the brightness corresponding to the velocity value of the note when the E3 note is displayed in the score data. When a G3 note is generated from the score data and a signal is generated, flow data is generated by generating a control signal to output white light at a brightness corresponding to the velocity value of the note.

Although the control signal generation unit 130 is not shown in the drawings, the administrator may further include a reference setting module to set the selection criteria and operation patterns. Before the moving lighting unit 110 is operated through the reference setting module, the selection criteria and operating patterns may be set or the selection criteria and operating patterns may be changed after the moving lighting unit 110 is operated.

Meanwhile, the control signal generation unit 130 is not limited to the above-described example, but is a method for generating flow data when a plurality of moving lighting units 110 are provided, and when one moving lighting unit 110 is provided. The flow data can be generated by combining the method of generating the flow data, and various messages defined in the MIDI protocol of the MIDI sound source can be mapped to a specific lighting, channel, and value.

Here, the control signal generation unit 130 transmits the generated flow data to the lighting control unit 140.
