Topic: External screen
What is the preferred technical way to transport your vdj skin to a diy midi controller with one usb connection (like the denon and Pioneer controllers)?

There's no preferred way.
The "easiest" way would be for that controller to contain a screen that's shown as a display under windows/mac os.

Now the way AlphaTheta (Pioneer) and InMusic (Numark, Denon, Rane e.t.c.) does it is different:
They have a microcontroller that draws graphics on the screen based on the MIDI data they receive.
So, for instance, they "read" the value of let's say MIDI note 0x30 at channel 0 that can take up to 128 values (o to 127) and then, based on that value they set the JOG Rotation Disc at an angle.
They follow pretty much the same logic for all the elements they show up on screen.
For more complex displays, they follow exactly the same logic, but they use HID protocol instead which has some advantages over MIDI at sending big chunks of data / complex data.
 

Hi thnx for your reply.

For instance how does the main computer, where vdj is running, see the screen of a Denon Prime, as its only have an usb connection.

I have seen vdj had a skin for this controller. Is this transported via HID?
