@Nathan > Sorry, the beat jump pad values are not user-configurable.
You could certainly change the MIDI mapping if you like, the default rekordbox pad modes don't match the labels of the RX2 buttons as the hardware itself (when used in stand-alone mode) only offers certain functions, but when connected to rekordbox, matches the modes available on other DDJ controllers. You can find the diagram and list of functions here.
Simply analysing tracks in rekordbox does not make them available for the RX2; you must export them to that USB drive.
