When I connect a USB storage device (that I've previously exported tracks to from rekordbox) to this unit, the caution "rekordbox Device Library Plus not found!" appears. Why?
There is no library (Device Library Plus) in the USB storage device that can be read by the unit.
Please convert your library to [Device Library Plus] in rekordbox for Mac/Windows before using the unit.
You can learn how to convert to [Device Library Plus] [here].
