+# CueHarbor Starter Instruments
+
+Multisampled instruments for the CueHarbor browser DAW library track (`src/audio/multisample`). Every file is **CC0-1.0 or public domain**; nothing here needs attribution and nothing is under CC-BY, Sampling+, or custom "royalty-free" terms.
+
+The app reads `catalog.json` at the root, fetches one preset (`.sfz` or DecentSampler `.dspreset`) when you pick an instrument, and streams each WAV the first time its zone plays. Sample paths in presets are relative to the preset file.
+
+## Layout
+
+```
+catalog.json                     { "instruments": [{ id, name, license, path, bytes, description, ... }] }
+<id>/instrument.sfz | .dspreset  preset the app loads (path in catalog.json)
+<id>/instrument.sfz              (dspreset instruments also ship an SFZ alternate with release envelopes)
+<id>/samples/*.wav               PCM WAV, original sample rate and bit depth (44.1/48 kHz, 16/24-bit)
+<id>/provenance.json             per-file source URL, source filename, license, mapping and format
+```
+
+Sample files are kept at their source resolution (no resampling, no bit-depth reduction). Processing was limited to trimming leading/trailing digital silence (below −66 dBFS before the attack, −80 dBFS after the tail), a short fade on trimmed tails, and, for long piano/bell decays, a length cap with a 1 s fade (felt piano 12 s, grand 16 s, upright 20 s). Octave naming in the sources was checked per folder with pitch detection, so roots are correct MIDI notes. The kalimba is retuned to equal temperament with per-zone `tune`.
+
+Velocity layers, round-robins (`seq_length`/`seq_position`, DecentSampler `seqMode="round_robin"`) and release-trigger samples are mapped wherever the source has them.

+Notes:
+- VSCO-2 CE's bundled Readme.txt asks that the samples not be resold as-is and encourages credit; the repository LICENSE is the full CC0 1.0 text, which governs.
+- Karoryfer Emilyguitar's readme carries an older "royalty-free, copyright 2014" line; the repository LICENSE (by the same author) is the full CC0 1.0 text.
+- The felt piano was released by its author, Tom Guder, as "Public Domain" (Polyphone soundfont page license field and the author's forum post linking the WAV set).
+- The synth choir is a synthesized (ZynAddSubFX) choir pad; no recorded CC0 choir multisample was found.
+- No CC0 source with separate microphone positions was found for strings, so `string-section` has one (main) mic.

+Credit is not required, but thanks to Versilian Studios (Sam Gossner), Ivy Audio (Simon Dalzell), Tom Guder, FreePats (Roberto), and Karoryfer Samples (D. Smolken).
