Coming soon macOS app Prepare music and USBs

Check a rekordbox USB export before your next set

USB Check inspects an existing rekordbox export without changing it. Choose the export or the mounted USB itself, select a supported player profile and review findings about referenced music, rekordbox analysis files and the drive layout. A saved report keeps the selected export, player choice and inspection date together for later reference.

The aim is to catch visible problems early and explain what a finding means. A copied export folder can be checked for contents, but checking the mounted USB itself is needed to see its drive layout. Unknown or unsupported details stay marked as unchecked rather than being treated as passed.

Availability

This page previews one of nine focused tools planned for a single forthcoming Mac app. The tools are separate workflows inside that app, not browser utilities or nine separate downloads. A public download is not available, and no release date has been announced.

How it works

A clear, reviewable workflow

01

Select the export

Choose an existing rekordbox USB export or a copied export folder; select the mounted USB itself to inspect its layout.

02

Choose a player profile

Select CDJ-2000NXS2 or CDJ-3000 so the read-only checks use the named profile.

03

Review the report

See problems, warnings and checks not performed, then use the corrective guidance to decide what to verify next.

Supported files and libraries

What you can use

Check the supported files and library requirements before choosing a tool.

Export format
Legacy Device Library with PIONEER/rekordbox/export.pdb
Player profiles
CDJ-2000NXS2 and original CDJ-3000
Checks
Referenced media, basic analysis-file checks and drive-layout context from the mounted USB
Does not do
Write, repair, format, speed-test or certify playback on hardware

Compatibility note

OneLibrary-only exports are unsupported. The checker does not listen to the audio, verify every rekordbox database detail, inspect firmware, test USB health or play the drive on a player. A report can identify known issues; it cannot promise that a device will recognize or play the drive.

Useful now

Review your rekordbox library setup

For preparation you can do now, start with a clear folder and export routine. Our rekordbox management guide covers practical organization steps; for a current device-specific result, consult the player maker’s instructions too.

Questions and answers

About USB Check

Does USB Check fix or format the drive?

No. It only reads a supported export and prepares a report. Reformatting erases a drive, so that work requires a separate backup and a fresh export in rekordbox.

Does a clean report mean the USB will play?

No. The tool does not test real hardware playback, firmware, sustained read speed or every export structure. It reports the checks it can perform and clearly marks checks it did not perform.

Can I check an export copied to my Mac?

Yes, for export contents. A copied folder cannot show the original USB’s drive layout, so select the actual mounted USB when you want that part checked.
