Flagship Feature
File Consolidation
One folder. Zero broken links.
Scattered music files across random folders? Cadence moves everything into one organized folder by artist, then rewrites the paths directly inside your rekordbox and Serato databases. Your DJ apps never lose track of a file again.
Complete Overview
rekordbox + Serato in one window.
Stop juggling apps. Browse your full collection from a single interface — see playlists, crates, metadata, and track counts side by side. Filter, sort, and jump between libraries instantly.
Smart Detection
Safe Duplicate Finder
Find doubles. Review first. Undo always.
Cadence intelligently groups duplicates by match type — exact copies, same name different location, shared across platforms. Review every group, pick what stays, and clean up with confidence. Nothing touches your Trash without your say-so.
More Tools
Everything your library needs
Every tool includes preview, backup, and undo.
Safety First
Every meaningful action is
previewed and reversible.
Preview Before Acting
See exactly what will change before anything moves.
Automatic Backups
Your library state is preserved before every operation.
Trash, Never Delete
Removed files go to trash, not oblivion.
Undo Everything
Changed your mind? Roll it back completely.
We built Cadence for DJs who've been burned before. The ones who've lost cue points to a “smart” cleanup tool, or watched a folder reorganization break 200 playlists. Your years of collected music deserve better than crossed fingers and a prayer.
Native macOS App
Built native for macOS with SwiftUI performance.
Fast, lightweight, and designed for your workflow.
FAQ
Questions? Answered.
Cadence reads your library databases to display and analyze your collection. Any modifications (like removing duplicates) are done safely with automatic backups, and files are sent to Trash — never permanently deleted.
No. Cadence works with either library individually, or both. If you only use rekordbox or only Serato, it works great for single-library management too.
Cadence is currently in invite-only beta, and all features are free for beta users — no credit card required. After beta, there will be a free tier for core browsing and health checks, plus paid Pro and Max plans for advanced features. Request access or join the waitlist to get started.
Most library tools treat your collection like a spreadsheet — Cadence treats it like a patient. It's a native app built safety-first: every destructive action requires confirmation, includes automatic backups, and can be undone. No cloud syncing, no format conversion rabbit holes — just a clean, focused toolkit for keeping your library healthy.
Cadence is a native desktop app. macOS is supported first, with Windows on the roadmap. Join the waitlist to be notified when your platform is ready.
No. Cadence focuses on file-level operations (duplicates, paths, metadata) and library health. It does not modify cue points, beat grids, or loop data.
