-If there'​s ​an LED behind the button, ​that is typically ​controlled by sending a message to the controller ​with the same first two bytes (status and note numberthat the controller sends when the button is pressed. As for the value byte, for LEDs that can only be turned on or off, typically ''​0x00''​ turns it off and ''​0x01''​ or ''​0x7F''​ turns it on. For multi-color LEDs, the color is typically controlled by sending different values. Which ones correspond to which colors should be in the MIDI specification document for your controller. If they are not, you will have to look at mappings for other DJ software, or just try a few different values.+If there'​s ​LED behind the button, ​usually it can be controlled by sending a message to the controller ​using the same status and note number that the controller sends when the button is pressed. ​
