# Tapkit sampler one-shots

All 25 bundled sampler WAV files are **CC0 1.0 Universal**. See `CC0-LICENSE.txt`.

## Original electronic sounds

Twenty one-shots are generated offline by the deterministic TypeScript recipes
in `scripts/prepare-sampler.ts`: a saturated deep house kick, sub drops, 808 glides, Reese/wobble/
growl basses, rave/supersaw/acid stabs, warm house keys/chords/organ/plucks, risers, impacts,
laser/zap, a slowing tape-stop chord, ring modulation and air horn. They contain no sampled commercial products or song excerpts.
The generated sounds are dedicated under CC0.

## Format and preparation

Mono 44.1 kHz / 16-bit PCM, 0.32–2.5 seconds, with clean boundary fades.
Rebuild using `node --import tsx scripts/prepare-sampler.ts`. Preparation needs ffmpeg;
curl downloads the three public source MP3s if `.artifacts/sampler-vocals/` has no cache.
The app needs no synthesis, decoder tools, downloads or effects processing at runtime.

Pad IDs are stable across bank revisions, independently of sample filenames, so
replacing a factory sound preserves users' custom keys and pad positions.
