Library
DJWhat it's for — The Library screen gives you a searchable, filterable view of all your tracks across every connected source. Browse, find the right track, and send it to Track Prep (where you can also assign it to a Cue Pad).

The screen, region by region
Source tree (left panel) — A tree listing every available track source:
- USB — Tracks on connected Pioneer USB drives, organised by playlist and folder as they appear in your rekordbox library.
- Local — Tracks in your configured local music folders.
- Live decks — Tracks currently loaded on connected Pioneer CDJ/XDJ players are shown at the top with a deck badge, so you can quickly find and prep what is playing right now.
Track list (main area) — Rows for every track in the selected source. Each row shows:
- Title and artist
- BPM — detected or rekordbox-confirmed tempo.
- Key / Camelot — musical key with a compatibility indicator relative to the track playing on the master deck (green = compatible key, amber = relative minor/major, grey = no relation).
- Genre badge — genre tag from your library.
- MATCH badge — lights up when the track's key and BPM are compatible with the currently playing master track.
- PREPPED badge — lights up when CueSync has a completed analysis for the track.
Search bar (top of track list) — Filter by title, artist, or genre. You can also filter by BPM range — type a number like 128 to find tracks within ±4 BPM, or a range like 120-130 for exact bounds.
Sort controls — Click column headers to sort by BPM, Key, Title, or Artist.
Common tasks
- Browse a USB library — Expand the USB node in the source tree. Navigate playlist folders the same way they appear in rekordbox.
- Find a track by BPM — Type the target BPM in the search bar (e.g.
128). The list narrows to tracks within ±4 BPM of that value. - Find a harmonically compatible track — The KEY column shows compatibility with the master deck's current key. Tracks marked MATCH are in a compatible key.
- Send a track to Track Prep — Double-click any row to open it directly in Track Prep.
- Assign a track to a Cue Pad — From the track list within Track Prep, right-click a row → Assign to Pad. The Assign Pad dialog opens; pick the target bank and pad position. (See the gotcha below about where this option appears.)
- Check which deck a track is on — Tracks loaded on a connected deck show a deck-number badge on the left of their row.
Tips & gotchas
- No USB drive mounted — the list is empty. Connect a Pioneer USB drive or configure local folders in Settings → Library to see tracks.
- PREPPED badge means analysis is complete. Tracks without the badge show an analysis prompt when you open them in Track Prep, and auto-analysis will run if Auto Pilot is not armed.
- Assign to Pad is available from the track list inside Track Prep. When you browse tracks within Track Prep, right-click a row to assign it to a pad; the standalone Library screen may not show this option.
- The MATCH indicator updates live. As the master deck changes tracks, key-compatibility indicators across the whole list update immediately. Use this during a set to spot upcoming tracks that will mix well.
- Local folders need to be configured. Go to Settings → Library → Local Sources to add folders. CueSync scans them and makes tracks available under the Local node.
