rekordbox vs STEM

rekordbox is DJ software for managing music and preparing and performing sets. Its tools cover track analysis, library setup, gig preparation and playback, with versions for Android, iOS, macOS and Windows. Cloud Library Sync uploads tracks and playlists to Dropbox for access across devices; Cloud Analysis is described as reducing track-analysis time by up to 35%. Users can separate tracks into vocals, drums, bass and instrumental parts for playback. The mobile apps provide track-management and performance functions and support DJing on a phone or tablet. A compatible controller connects to the mobile app over USB or Bluetooth. The free plan costs nothing and includes basic music-management and DJ features, 1,000 cloud tracks under stated conditions and one synced device. Paid plans add device allowances and, for Creative and Professional, Dropbox storage. The maker lists 24/7 inquiry-form support, but not telephone support. It has also reported a PRO DJ LINK vulnerability and recommends updating rekordbox and using password-protected Wi-Fi.

STEM is a free web platform for bands and music collaborators to upload, mix and discuss song stems. Its multi-track mixer handles uploaded stems, while invited members can view or work on projects in real time. Timed comment threads can be attached to individual tracks or the master track. Share links use customizable permissions, allowing songs to remain private or become public. Users can render stems to MP3, save mix snapshots and export renders. Songs can be grouped into playable, shareable lists for albums, EPs, setlists or work sessions, and can carry lyrics, chord charts, reference tracks, session notes and other files. STEM is intended for discussion and shared decisions rather than music creation like a full DAW. Certain features require a Google account. The privacy policy says uploaded audio is accessible to the user and explicitly shared people. The Free plan costs nothing, with limited version history.
