Catch true duplicates without punching holes in your playlists
Use Find Duplicates. Lexicon compares tracks by their audio signature rather than just filenames or tags, so genuinely identical audio gets flagged even when the metadata reads differently. Because it works across your whole library, you can clear out the copies and your playlists stay correct: the good track stays put and the duplicate is the one that goes. Run this before a big USB export so you are not carrying three versions of the same track into the booth.
Find broken tracks before they find you mid-set
Run Find Broken Tracks. It scans your entire library and checks that every track still exists and that the audio file actually plays. That is the difference between catching a dead file at home and discovering it live with a full floor. Fix or archive whatever it flags, then refresh your DJ app so it drops the stale links to files that are gone. See the Find Broken Tracks manual page for the full walkthrough.
Clean your titles first, then let the tools work
Reach for Smart Fixes. Cluttered Artist and Title fields quietly sabotage every other tool that reads them, from duplicate scans to tag lookups. Lexicon's Smart Fixes tidy up messy titles so your library is consistent and the rest of your cleanup behaves predictably. Make this your first pass on any freshly imported batch before you start matching or tagging, and the downstream steps get noticeably more accurate.
Know why your cues drift, and let Lexicon fix it
Mind the 26/50 ms silence. Different DJ apps parse MP3s slightly differently, and some end up adding a tiny bit of silence (26 or 50 milliseconds) to the start of a file. That is enough to shift your cue points and beatgrids when you move a track between apps. Lexicon scans and adjusts your tracks automatically every time you import or sync, so most of this is corrected before you ever notice it. The Convert Library manual page explains what is happening under the hood.
Move Rekordbox cues across without losing your memory cues
Cue Destination: Both, then Default. When importing from Rekordbox, set Cue Destination to "Both" so your memory cues are merged into hot cues inside Lexicon, with any duplicates from the merge hidden rather than deleted. When you sync back to Rekordbox, choose "Default" and those hidden memory cues are restored to their original positions. If you need to force a conversion instead, the sync step also gives you "All to hot cue", "All to memory cue", and "All to hot and memory cue". The Sync to Rekordbox manual page covers each option.
Mind Rekordbox's hot cue ceiling
16 hot cues, but only 8 arrive via XML. Rekordbox itself can handle up to 16 hot cues, but it only imports a maximum of 8 through XML. If you lean on a dense grid of hot cues, know that the back half may not survive the trip, so put your most important cues in the first eight slots. It is a small planning habit that saves a nasty surprise the first time you load a converted library.
