A Fast, Simple Way to Sync New Lexicon Playlist Folder Trees to Engine DJ (No Full Rebuild Needed)

I’ve been searching for a quicker way to push new playlist folder trees from Lexicon into Engine DJ without doing a full sync rebuild or waiting through a long re-analysis cycle. Many DJs have run into this for years (there are posts going back to 2021), and the common fixes were either manual work inside Engine DJ or a full rebuild via a full sync from Lexicon. After testing different setups, I found a fast method that works in minutes, and I wanted to share it here.

What was the issue?
New playlist folder trees coming from Lexicon would show up in Engine DJ, but the parent folder didn’t display the tracks inside its child playlists. In simple terms, DJs couldn’t click the main folder and see all the tracks inside it, which is one of Engine’s most useful features.

Why did this happen?
This happened because of how Lexicon sent the playlist structure to Engine DJ. Engine can show the parent folder’s tracks, but only when Lexicon delivers the entire folder tree at once. When only individual playlists were selected for sync, Engine never received the full structure, so the parent folder stayed empty.

How I resolved it: (see images for reference)

  • In Lexicon, I selected only the top-level parent folders and did not select the playlists under them.
  • I used Modified Sync to Engine DJ.
  • Engine DJ automatically created the full folder tree, added all child playlists, and showed all tracks at the parent level while keeping all of my existing track analysis, cues, BPM, and waveform data. No new analysis was required because the tracks already existed and were previously analyzed in Engine.

Why this matters:

  • No full rebuild or full sync is needed.
  • No manual crate creation in Engine DJ.
  • No database resets or risky edits.
  • All existing grids, cues, BPMs, and waveforms are preserved.
  • No new analysis is triggered if the tracks were already analyzed.
  • The entire process took about 2 minutes, and everything appeared exactly where it should.

If you use Lexicon to build new playlist folder trees and still want Engine DJ to show all tracks when you click the parent folders, this method is fast, reliable, and keeps your library completely intact. It has noticeably streamlined my workflow, and I hope it helps anyone dealing with the same issue.
