TagWave — Built for people who live music.
TagWave detects musical key with precision beyond Rekordbox and Serato, classifies every track by energy, organizes your library into crates — and syncs everything to Serato, Rekordbox and Engine DJ in one click. The complete alternative to Mixed In Key and Lexicon DJ — one tool for key/BPM analysis and library management — for DJs and producers on macOS and Windows.
TagWave is DJ library management built for your DJ workflow — Serato organization, Rekordbox playlists and Engine DJ sync, with clean music metadata (key, BPM, genre) enriched from Spotify and Apple Music.
Why TagWave instead of Mixed In Key or Lexicon
- vs Mixed In Key: Mixed In Key only analyzes (key, BPM, energy). TagWave analyzes and manages — crate organization, batch tagging, duplicate detection and one-click sync to your DJ software. And Mixed In Key charges again for every major version (MIK 10 owners paid again for MIK 11); TagWave Lifetime includes two years of updates and never stops working.
- vs Lexicon: Lexicon organizes your library but relies on external analysis. TagWave does its own key/BPM detection and the library engine in a single native app — no subscription lock-in required, with a one-time Lifetime option.
- Try before you pay: 14-day free trial with everything unlocked, no credit card. If you don't subscribe, you keep a free mode to view and organize.
What TagWave does
- Sub-beat BPM & key detection on every track, written as a consistent ID3v2.4 tag block with album art.
- Automatic metadata — pulls and cross-checks key, BPM, genre, album, year and cover from Spotify and iTunes.
- Duplicate detection — matches by title and artist, finds the same track at different bitrates and merges it.
- One naming convention for your whole library, applied in seconds.
- One-click sync to Serato, Rekordbox and Engine DJ, preserving cue points, hot cues and beatgrids.

Frequently asked questions
- What is TagWave? A DJ library engine that detects key, BPM and energy, organizes tracks into crates and syncs to your DJ software.
- What formats are supported? MP3, AIFF, WAV, FLAC, ALAC, AAC and OGG.
- Is there a cloud component? Where does my data go? Everything runs locally. Metadata lookups are anonymous HTTPS calls — no library upload.
- Will it overwrite my Rekordbox cue points? No. Sync preserves cue points, hot cues, beatgrids and key-lock.
- Does it work with older versions of Serato, Rekordbox or Engine DJ? Yes — Serato DJ Pro 2.x–4.x, rekordbox 6 and 7, and Engine DJ 2.x–3.x. Older releases may need an update, and TagWave warns you instead of failing silently.
