You don't need any of the build steps below.\n\n## Building from source\n\nThis extension depends on the **Ableton Extensions SDK**\n(`@ableton-extensions/sdk` and `@ableton-extensions/cli`), which is **not yet\npublished to npm**. `package.json` references both as local tarballs under\n`vendor/`:\n\n```jsonc\n\"@ableton-extensions/sdk\": \"file:./vendor/ableton-extensions-sdk-\u003cversion\u003e.tgz\"  // dependency\n\"@ableton-extensions/cli\": \"file:./vendor/ableton-extensions-cli-\u003cversion\u003e.tgz\"  // devDependency\n```\n\nSo before `npm install` will work you have to drop those two tarballs into\n`vendor/` yourself.\n\n### 1. Get the SDK and CLI in place\n\nDownload the Extensions SDK zip (e.g. `extensions-sdk-\u003cversion\u003e.zip`) from the\n[Extensions SDK site](https://ableton.github.io/extensions-sdk) and unzip it.\nInside you'll find two tarballs:\n\n```\nableton-extensions-sdk-\u003cversion\u003e.tgz\nableton-extensions-cli-\u003cversion\u003e.tgz\n```\n\nCopy both into a `vendor/` folder at the root of this repo:\n\n```sh\nmkdir -p vendor\ncp /path/to/ableton-extensions-sdk-\u003cversion\u003e.tgz vendor/\ncp /path/to/ableton-extensions-cli-\u003cversion\u003e.tgz vendor/\n```\n\nThe filenames must match the `file:./vendor/…` paths in `package.json` exactly\n(they carry the version).\n\n### 2. Install dependencies\n\n```sh\nnpm run install:all   # installs the host, then src/dialog\n```\n\n### 3. Build and package\n\n```sh\nnpm run build       # vite-build the dialog + esbuild the host\nnpm run package     # produce Paulstretch-\u003cversion\u003e.ablx\n```\n\n### 4. Run\n\n```sh\nnpm start\n```\n\nopens Ableton Live against the local build (Live must have Developer Mode\nenabled in Preferences → Extensions).\n\n## Dev tips\n\n- `npm run dev:ui` — run the dialog standalone in Vite for UI iteration.\n  In standalone mode the file menu / drag-drop are active; the Apply bar\n  is hidden.\n- The dialog detects \"host mode\" by checking whether `window.__INITIAL_DATA__`\n  contains real values (vs the placeholder text from `index.html`).\n- The .ablx packager includes the entire Vite-built `dist/dialog/` tree as\n  runtime assets (see `package.js`'s `ABLX_INCLUDES`).\n\n## License\n\nPaulstretch For Live is licensed under the GPL v2.0\n\nThe bundled dialog ships two fonts, each under the\n[SIL Open Font License 1.1](https://openfontlicense.org). Their license texts\nare included both in this repo and inside every `.ablx`, under\n`src/dialog/public/licenses/` → `dist/dialog/licenses/`:\n\n- **Inter** — © The Inter Project Authors — `Inter-LICENSE.txt`\n- **JetBrains Mono** — © The JetBrains Mono Project Authors — `JetBrainsMono-LICENSE.txt`\n\n[libpaulstretch](https://github.com/olilarkin/libpaulstretch) is also GPL v2.0\n\n## Credits\n\nPaulstretch For Live.
