Left Hand Labs MusicCredits and licences
Drum kits v1.0.0 and the free practice plugin.
Applies to all nine LHL drum plugins (VST3 + standalone, Windows) and the All 9 Kits bundle. Each kit folder also ships CREDITS.txt, PROVENANCE.csv (output file → source kit, instrument, licence) and a Licenses folder with the full licence texts.
All drum sounds are real acoustic drum recordings from open-licence sample libraries (CC BY 4.0 and CC0 1.0). No samples come from commercial, personal or unlicensed libraries. The samples are not encrypted: each kit folder contains plain FLAC and SFZ files.
Drum samples provided by DrumGizmo.org (CC BY 4.0).
CC0 items need no credit. We list them anyway as a courtesy and so you can see exactly where every sound came from.

How the recordings were changed (CC BY 4.0, section 3(a)(1)(B), all kits)
Individual hits were selected from the original multi-microphone recordings; for each hit the close, overhead and room microphones were mixed down to stereo; hits were trimmed, level-matched, sorted into velocity layers and round robins, saved as FLAC and mapped in SFZ files (which apply fixed level, envelope and, for some drums, gentle EQ settings at playback); the whole kit was loudness-normalised. No synthesized sounds, impulse responses or reverb were added to the sample files. The plugin can add its own optional effects at playback (big knob, Room, Tune).
