Load the next track to the desired virtual deck by using the mouse to drag and drop a file from the library, or use the keyboard shortcuts, shift + left arrow to load onto the left deck (or the active left deck when using 4 decks), or shift + right arrow to load onto the right deck (or the active right deck when using 4 decks).
Alternatively you can use the relevant track-load button(s) on your Serato DJ hardware.
