Conversion Limitations
There are a few limitations when converting between DJ apps since not every DJ app has every feature or uses it in the same way.
Cues
Traktor does not have colored cue points so any colors on your cue points will not be visible in Traktor.
Last Played
Rekordbox does not store last played date.
Serato & Engine DJ Playlist Folders
Serato and Engine DJ both allow tracks inside playlist folders. Other DJ apps and Lexicon do not allow this so any track directly inside a folder will not be visible in the Lexicon playlist folder or when converting to any other DJ app.
Remix Sets
Traktor remix sets are not currently supported.
Rekordbox
There are a few limitations and incompatibilities when using Rekordbox, you can read more about that here.
Serato
Serato FLIP is not currently supported.
Serato 3 does not support streaming tracks (Beatport, Tidal, etc) in crates. So if your playlists contain streaming tracks in Lexicon, you will not see those in Serato 3. Serato 4 and Serato 5 do not have this limitation.
If you use streaming tracks, make sure the correct streaming track service is enabled in the Serato settings or those streaming tracks will not show up in Serato.
Serato supports up to 128 beatgrid markers per track. A beatgrid with more markers, like a fluid beatgrid, is reduced to 128 markers when syncing, keeping the markers where the tempo changes.
Only Serato 5 has loops on hot cue slots (cue loops). When syncing to Serato 3 or Serato 4, those loops are saved loops only.
Djay Pro
There are some limitations when syncing to Djay Pro. More info here. Fluid Beatgrids are only imported from and synced to Djay Pro on macOS.
