# Yuzu shared drum bank — sound credits ## Yuzu acoustic selection Derived from AVL Drumkits / Black Pearl by **Glen MacArthur**.

This derivative sample selection remains CC BY-SA 3.0. Author information and the upstream license and README are included in `acoustic/`. No endorsement by the author is implied. ## Yuzu electronic selection FreePats synthesizer percussion, version 2022-07-18, by **Roberto**. Created with Yoshimi and Geonkick, edited with Audacity. Source: https://github.com/freepats/synthesizer-percussion Revision: 39bbabce8e0e10aa259d5d94fca329f668733185 License: **CC0 1.0 public domain dedication**. https://creativecommons.org/publicdomain/zero/1.0/ Converted from FLAC to WAV and trimmed/faded as above. Original README and license are included in `electronic/`. Both selections are bundled locally. No paid VST, subscription, or external sample CDN is required. Source and derivative SHA-256 hashes, tags, processing, and velocity ranges are recorded in `src/sample-bank/samples.json`. ## Yuzu DRS Studio selection Derived from **DRSKit v1.0** by Lars Muldjord / Bent Bisballe Nyeng and Jes Eiler of DRSDrums. SFZ port and FLAC conversion by kinwie. Source: https://github.com/sfzinstruments/DrumGizmo.DRSKit Revision: b01448990a31f722542f1812e56159a97a6a2a82 License: **Creative Commons Attribution 4.0 International**. https://creativecommons.org/licenses/by/4.0/ This selection uses kick-front, snare-top, hi-hat, tom close microphones and the left overhead for crashes. It retains the upstream velocity boundaries and up to two alternate recordings per layer (82 samples total). Changes: FLAC to PCM WAV conversion, silence trimming with a 2 ms leading margin, 20 ms tail fade, a six-second maximum length, and one gain per instrument to preserve the relative loudness of recorded dynamics. Author README and full license are in `drs/`. No author endorsement is implied. ## Yuzu Red Zeppelin selection Derived from **AVL Drumkits / Red Zeppelin** by Glen MacArthur, under the same CC BY-SA 3.0 terms and author exception described for the acoustic selection above. Pinned source revision: b06cb2c27359cbc68a830a82bddced05bd73d1a0. 35 recordings cover seven voices at five velocity layers. Modified by conversion to WAV, silence trimming with a 2 ms margin, 20 ms tail fade, six-second cap, and 0.9 gain. This renamed selection remains CC BY-SA 3.0. Complete author README, license, and exception are included in `red-zeppelin/`. ## The Silence Say It — original song kit Nine song-derived WAV hits and their playback gains are preserved unchanged from the original demo kit that Justin endorsed in this task. This kit has kick, snare, closed-hat, crash and high-tom recordings; open-hat and low-tom articulations are borrowed from the AVL acoustic bank and retain its credits. Runtime playback reuses the byte-identical, already-published assets under `/local-media/the-silence-say-it/kit/`. This does not grant a standalone sample- library redistribution license. Source timestamps, hashes, and the scope of song permission remain in the bank metadata. No re-separation was performed. ## Save the Best Part — original hats and cymbals Six hits extracted from Yuzu Patch's supplied Suno hi-hat and cymbal exports: three alternate closed hats and three alternate cymbals. Justin approved their song-context audition on September 13, 2026. Source attacks were trimmed to mono 44.1 kHz PCM WAV with a 15 ms end fade; runtime gains preserve the audition's levels. The current live pad envelopes shape their decay. Kick, snare, open hat, and toms reuse DRS Studio recordings with the original credits and CC BY 4.0 terms above. The six song-derived samples are for use in this song; no standalone sample-library redistribution license is granted. Source and output hashes, timestamps, gains, and review scope are in the bank metadata. ## Rhythm's Edge, Snare Maze, and Keep the Little Things — listening drafts Each song has three hi-hat and three cymbal samples extracted from the supplied Suno exports. They are pending listening review. Source attacks were trimmed to mono 44.1 kHz PCM16 WAV with a 15 ms end fade, then assigned playback gains for comparison with the existing kit. The current live pad decay remains in use. These song-use-only samples carry no standalone sample-library license. Rhythm's Edge and Snare Maze reuse DRS Studio for their other voices, under the CC BY 4.0 terms above. Keep the Little Things reuses AVL acoustic voices, with Glen MacArthur's credits and CC BY-SA 3.0 terms above. Source hashes, trim times, output hashes, and gains are recorded in the sample-bank metadata. Pocket Groove also has three pending-review hi-hats from its supplied Suno MP3 export, converted and trimmed by the same process. All other voices, including cymbal, retain the DRS Studio sources and CC BY 4.0 attribution above. ## Song-derived snare contacts — October 8, 2026 Live drums now uses one short snare contact from each song's existing aligned drum source, superseding that song's earlier snare selection above. Other voices retain their original credits. The web catalog has sixteen contacts; the offline native catalog includes only its ten released songs. Original drums still plays the recording and remains the default. The accepted playback clip keeps its specific listening approval; the remaining contacts retain machine-draft status. Preparation uses short source crops, fades and attack-level normalization, without asserting clean isolation. Exact source and output hashes, crop times, processing and review scope are recorded in `song-snares/provenance.json`. The registered audio was approved by Justin for the existing internal-testing release. Commercial content and model-output clearance is not attested, and this does not grant a standalone sample-library license.
