Having trouble with this.
I've seen a YouTube video about mapping NI controllers to Rekordbox with Controller Editor, but unfortunately, the latest version of the Controller Editor does not include the X1 MK3, even though the latest update notes says it does.
Inside Rekordbox I've mapped several functions, but they won't respond when I take it out MIDI mode, and only one responds when the controller is in MIDI mode.
Any advice?
