What you get per item
One folder per song, one WAV per lane with the producer's lane name, the unmastered mix of the song, a MIDI folder where the session had notes, and the manifest row with one instrument label per lane.
Manifest fields: song_id, creator_id, daw, bpm, key, sample_rate, stems, lane_label, duration, has_midi.
No separation model touched these files. Each WAV is one lane of the producer's session, printed from the original project with its plugins loaded. Each lane carries one of 53 instrument labels in the manifest, taken from the producer's own lane name.
Every delivery includes the unmastered mix of each song, summed from its lanes, so a separation model learns from the source the parts came from, not from a guess. Train on these pairs and it pulls cleaner parts out of any finished mix. A mastered reference of the same song on request.
Rights
Every creator in this set accepted terms that name AI training. Every stem is printed from the creator's own session, part by part, and the manifest says which session it came from. Every creator sells on WeMakeDanceMusic, a music production marketplace online since 2012, under terms that name machine learning, keeps ownership and is paid on every licence. Nothing is scraped. Deliveries are anonymised: pseudonymous IDs, no titles, no artist or producer names.
