The eight files above are single velocity-layer one-shots taken from **MuldjordKit**, an
acoustic drum kit recorded by **Lars Muldjord** (drum kit v3.0, originally captured for
DrumGizmo). They were acquired 2026-09-02 from the FreePats stereo derivative of the kit
(version 2020-10-18, assembled by roberto@zenvoid.org).

Each file was processed for Practice Beat as follows: decode FLAC, trim leading silence,
peak-normalise to -1.0 dBFS, cap the length per voice, apply a short tail fade-out, and
export as stereo 44.1 kHz 16-bit WAV. They drive Practice Beat's live step-grid playback
and the accompaniment export; no drum loops are used.
