Changes in Note Quest V3.4: extracted individual MP3 files from the above packages, copied byte-for-byte without trimming, normalization, EQ or re-encoding. Playback uses nearest sampled root with playback-rate adjustment and selects a real velocity file. This does not reproduce all SFZ resonance/release/pedal features. Source layer counts do not imply all recordings are loaded into memory.

Appropriate attribution, source/license links and this changes notice must accompany redistribution. Do not imply endorsement by Alexander Holm, Jan Forst or Yamaha. The license permits sharing/adaptation including commercial use subject to its terms; no additional restrictions may be imposed on these recordings.

TimGM6mb: NOT included in the deployable public directory. V3.3's embedded derivatives had incomplete provenance. The unchanged V3.3 file is retained only as a private development baseline outside public/. Do not deploy archive/.
