[2] Structure of Control Unit 44 of Display Unit 43 FIG. 2 shows a functional block diagram of the control unit 44 that controls the display of the display unit 43. The control unit 44 includes an application determination unit 45 and a display image control unit 46.
The computer 2 uses the name of the operating music playback application software 21, the BPM value previously analyzed by the music playback application software 21, and the music analysis data such as the progress status, beat position, and elapsed time of the music data being played. It is output to the control unit 44 via the cable 3.

The application determination unit 45 determines the type of the music reproduction application software 21 running on the computer 2. Specifically, the application determination unit 45 classifies the music playback application software 21 from the software name, product number, etc. written in the header of the music playback application software 21 output from the computer 2 via the USB cable 3. To judge.
Further, the application determination unit 45 receives the music analysis data output from the music reproduction application software 21 and outputs the music analysis data to the display image control unit 46. The application determination unit 45 may determine the type of the music reproduction application software 21 based on the received music analysis data instead of the name of the software written in the header.

The display image control unit 46 controls the display image displayed on the display unit 43 according to the type of the music reproduction application software 21 determined by the application determination unit 45.
When the music playback application software 21 running on the CPU of the computer 2 is a dedicated product of the DJ controller 4, the music playback application software 21 can be used to determine the BPM value of the music, the elapsed playback time of the music, the progress information of the music, and the music. Beat position information is output.

Based on this information, the display image control unit 46 displays the image G1 shown in FIG. 3 on the display unit 43. Specifically, the display image control unit 46 generates an image G1 that combines a BPM value image G11, a music reproduction elapsed time image G12, a beat position information display image G13, and a music progress image G14, and the display unit 43. Display above. Further, the display image control unit 46 generates a rotation display image G15 that rotates in synchronization with 33 RPM of the LP record according to the reproduction of the music based on the beat position information of the music, and rotates and displays the rotation display image G15 on the display unit 43. ..

On the other hand, when the music reproduction application software 21 is not a dedicated product and the display image control unit 46 is a general-purpose product that receives a specific MIDI, the display image control unit 46 displays the image G2 shown in FIG. 4 as the display unit 43. Display above. The display image control unit 46 generates an image G2 that is a combination of the BPM value image G21, the music reproduction elapsed time image G22, and the rotation display image G23, and displays the image G2 on the display unit 43. Since the music reproduction application software 21 does not output the music progress status information and the music beat position information, the display image control unit 46 regulates the display of the progress status image and the beat position image on the display unit 43. Display in.

Further, the display image control unit 46 displays the image G3 shown in FIG. 5 on the display unit 43 when the music reproduction application software 21 is not operating on the CPU of the computer 2. Specifically, the display image control unit 46 displays the logo image G31 of the manufacturer name of the DJ controller 4 on the display unit 43. Although not shown, when the input of the DJ controller 4 is analog PHONO / LINE, the display image control unit 46 displays an image showing an input state of "EXTERNAL INPUT".
The display image control unit 46 displays the image G4 shown in FIG. 6 on the display unit 43 when the music reproduction application software 21 is authenticating the connection with the DJ controller 4 on the CPU of the computer 2. The display image control unit 46 displays an image G42 indicating that connection authentication is in progress on the display unit 43 under the logo image G41.

[3] Actions and Effects of the Embodiment Next, the action of the present embodiment will be described with reference to the flowchart shown in FIG.
The application determination unit 45 determines whether or not it is connected to the computer 2 by the USB cable 3 (procedure S1).

When the application determination unit 45 determines that the computer 2 is connected, the application determination unit 45 determines whether or not the channel connected to the computer 2 is an active channel (procedure S3).
When the application determination unit 45 determines that the channel is not the active channel, the display image control unit 46 displays the image G3 shown in FIG. 5 on the display unit 43 (procedure S2).

When the application determination unit 45 determines that the channel is the active channel, the application determination unit 45 determines whether or not the music reproduction application software 21 running on the CPU of the computer 2 is a dedicated product (procedure S4).
When the application determination unit 45 determines that the product is not a dedicated product but a general-purpose product, the display image control unit 46 displays the image G4 shown in FIG. 6 on the display unit 43 and receives a specific MIDI from the computer 2. Whether or not it is determined (procedure S5).
When it is determined that the specific MIDI has not been received, the display image control unit 46 displays the image G3 shown in FIG. 5 on the display unit 43 (procedure S2).

When it is determined that a specific MIDI is received, the display image control unit 46 displays the image G2 shown in FIG. 4 on the display unit 43 (procedure S6).
When the application determination unit 45 determines that the product is a dedicated product, the display image control unit 46 displays the image G1 shown in FIG. 3 on the display unit 43 (procedure S7).

According to this embodiment, there are the following effects.
Since the display image control unit 46 displays the image G1 and the image G2 on the display unit 43 according to the type of the music reproduction application software 21 operating on the CPU of the computer 2, the DJ controller 4 is displayed according to the amount of information. Appropriate display can be performed on the unit 43.

Since the display unit 43 is arranged on the jog dial 421, it is easy for the operator to visually recognize the information regarding the music data being reproduced.
Since the display image control unit 46 displays the beat position information display image G13 and the music progress status image G14 that can be displayed by the music playback application software 21, the operator confirms the music progress status and is appropriate. DJ performance can be performed.
