There are two main issues with Traktor compatibility:
1.- All songs and playlists exported from lexicon to Traktor have the analyze blocked.
Traktor analysis is the best in class in dj softwares (IMO) so we should be able to export our libraries with tags and comments with the capability to be analyzed by Traktor
2.- All the album covers are wiped off the songs.
This is really a big problem, since the majority of our memory cues are visual and not having the art cover represents a really bid downgrade of implementing Lexicon in our workflow
