v0.17.1 - Migrate sample sources and remove websfz format support

[danigb]

Sample Sources Migration — Summary

Create with Claude code

Goal

Migrate all instruments from danigb.github.io/samples to smpldsnds.github.io repos, then remove the legacy websfz pipeline.

Completed

SplendidGrandPiano

• File: src/splendid-grand-piano.ts
• Changed BASE_URL to https://smpldsnds.github.io/sfzinstruments-splendid-grand-piano/samples
• Converted all sample names from hyphen to space format (PP-C3 -> PP C3)
• Fixed pre-existing MF/Mf case bug in FF layer
• Fixed MF layer mid-range: repo uses MF (uppercase) for C#1-C4 and Mf (mixed case) for low+high range
• Added space URL-encoding (%20) in src/smplr/load-audio.ts
• Added optional formats config (defaults to ["ogg", "m4a"])

ElectricPiano

• File: src/electric-piano.ts
• No longer extends SfzSampler — composes Smplr directly (same pattern as Smolken)
• Fetches raw .sfz files from smpldsnds, converts with sfzToSmplrJson()
• Added optional formats config (defaults to ["ogg", "m4a"])
• New URLs:
  • CP80: smpldsnds.github.io/sfzinstruments-greg-sullivan-e-pianos/cp80/CP80.sfz
  • PianetT: smpldsnds.github.io/sfzinstruments-greg-sullivan-e-pianos/planet-t/Pianet T.sfz
  • WurlitzerEP200: smpldsnds.github.io/sfzinstruments-greg-sullivan-e-pianos/wurlitzer-ep200/Wurlitzer EP200.sfz
  • TX81Z: smpldsnds.github.io/sgossner-vcsl/Electrophones/TX81Z - FM Piano.sfz

SFZ Parser: #define preprocessor

• File: src/smplr/sfz-convert.ts
• Added resolveDefines() step before tokenization
• Handles #define $VAR value directives used by smpldsnds SFZ files (e.g. #define $EXT flac)

Removed legacy websfz pipeline

All websfz support has been removed. The entire src/sfz/ directory was deleted along with the websfz converter:

Deleted file	What it was
src/sfz/websfz.ts	Websfz type definitions
src/sfz/sfz-kits.ts	Kit discovery URLs (3 danigb.github.io endpoints)
src/sfz/sfz-load.ts	SfzInstrumentLoader, fetchWebSfz
src/sfz/sfz-sampler.ts	Legacy SfzSampler class
src/sfz/sfz-regions.ts	findRegions() for Websfz data
src/sfz/sfz-regions.test.ts	Tests for findRegions
src/sfz/__fixtures__/cp80.websfz.ts	CP80 test fixture
src/sfz/__fixtures__/meatbass.ts	Meatbass test fixture
src/sfz/__fixtures__/grandpiano.ts	Grand piano test fixture
src/smplr/websfz-convert.ts	websfzToSmplrJson() converter

None of these were exported from the library. SfzSampler was orphaned after the ElectricPiano rewrite (nothing imported it). The test fixtures and findRegions() were only used by sfz-regions.test.ts.

Already on smpldsnds (no changes needed)

Instrument	Repo
Smolken (double bass)	smpldsnds.github.io/sfzinstruments-dsmolken-double-bass
Versilian	smpldsnds.github.io/sgossner-vcsl
Mellotron	smpldsnds.github.io/archiveorg-mellotron
DrumMachine	smpldsnds.github.io/drum-machines

Demo site improvements

• All 10 example components now show load progress as percentage
• SplendidGrandPiano and ElectricPiano pages have ogg/m4a format selector
• Version number from smplr/package.json displayed in page title
