broken or unplayable stem track in Traktor Pro? strip the stray stem flags Lexicon left behind and turn it back into a normal, playable track.
download freeyou might know this as traktor stems fixer — same free tool, just an honest new name. it only ever removed stem metadata; it never “fixed” anything. the full, paid library-repair tool that restores stems (and the rest of the Lexicon→Traktor damage) is traktor library fixer.
removes the <STEMS> block a track should never have had — the thing that makes Traktor treat a normal file as a stem deck.
unsets the stems bit in FLAGS and drops the RATING="STEM" marker, so nothing keeps re-flagging the track as a stem.
the result loads and plays like any other track. the only real fix when a stem is genuinely broken and won't play at all.
some stems just won't play.
a bad export, a half-imported pack, a stem flag stuck on a regular file —
and Traktor refuses to load it.
stems remover rips out the stem metadata so the track behaves like a normal file again. preview exactly what gets touched, then remove it in seconds — your original collection is never overwritten (it writes a .fixed.nml beside it).
point it at your main collection.nml and the playlist NML of stems you want stripped.
see exactly which tracks carry stem metadata before anything changes.
strip the stem flags and write a new .fixed.nml — original untouched.
stems remover changes metadata only. it never touches, moves or deletes the actual stem audio files — they stay exactly where they are on disk.
if you want the stem audio gone too, delete it yourself from your Traktor Stems folder. on a default macOS setup that's usually:
~/Documents/Native Instruments/Traktor/Traktor Stems
not sure where yours is? Traktor shows the exact path in preferences → file management — you can change it there too.
stems remover throws the stem data away. if your stems should work and Lexicon broke them, you want the opposite — TLF restores stem flags (and fixes the rest of the Lexicon→Traktor damage) on every sync.
