What I do is keep the same file structure used for VDJ on the SSD and create the Engine DB directly on the drive. It’s easier for syncing new files etc. Also any VDJ lists created can be imported to engine via iTunes so they can be used on the standalone side too. I don’t use Lexicon at all so just set the cue points and beatgrid on Engine separately. I don’t process a huge amount of new tracks so that method works for me.
