Your collection.
Already there.
Set Lab mirrors your rekordbox collection with no export. Click a record and it plays. Split it into stems on your own machine. Plug in the stick from last night and the set you played is already on the gig, and it asks you which records went off.
Desktop app on macOS. Web companion in the browser.
Six tools.
One library.
Open it and your whole collection, playlists and cues are already there, refreshed on their own, with no export. Proven on 15,077 tracks and 940 playlists.
Click any record and it is playing in about a millisecond, first play of the session included. A three-band colour waveform on the deck and on every row, in four switchable looks, sample-accurate around the playhead.
Every track carries a key you can trust, with Mixed In Key's answer winning where it exists. 8,603 tracks got their key back in one pass.
Drop a record on STEMS and it splits into vocals, drums, bass and everything else, on your own machine, offline, with a real percentage while it runs. The four parts land in your library with the parent's key, Camelot and tempo, in a Stems playlist.
Eight cue pads filled and snapped to the beat, the bar and the phrase, without touching cues you set yourself. Artist and title split apart, cover art pulled from your files and Discogs, and how rare each record is shown on the row.
Pick any record and Crate Dig walks Discogs by label, artist, style and credit to surface records you have never heard of, plus three fresh picks a day. Run a Shortcut on your phone mid-set and the record lands in your Track IDs playlist. Your last 20 playlists on any device.
Stay in the music.
