Original readme: licenses/organ.txt https://creativecommons.org/publicdomain/zero/1.0/ Changes for Guitar Crossroads: curated pitch and dynamic ranges, leading-silence and residual-tail trimming, moderate level balancing, WAV/MP3 conversion, pre-mixed drum microphones, prepared string sustain loops, and decaying electric-piano tails rendered from the original embedded loops. Brush sweep skin/wire microphones are premixed; individual sweeps receive tempo-aware fades during playback. Organ loop points and piano/electric-piano pitch corrections follow the source mappings. No source creator endorses this adaptation. These are subsets, not full libraries. Pinned source revisions are in manifest.json. Every original sample URL and SHA-256 checksum, with level adjustments, is listed in provenance.json. Metronome click/accent recordings are original synthesized one-shots generated by scripts/prepare-natural-audio.py for Guitar Crossroads.
