To remap the controls on your primary Serato DJ hardware, open the SETUP screen and make sure “Allow Serato Hardware Remapping” is enabled for your connected primary device in the MIDI Devices list under the MIDI tab. When this option is checked you will be able to use the MIDI assign feature to remap the functions of your primary Serato DJ hardware.

To restore all defaults, click the ‘Restore Defaults’ button in the MIDI tab of the SETUP screen. This will prompt you to save any custom mappings you have made and will unload your current MIDI.xml leaving you with a clean slate.
