Ableton RC Setlist

Ableton RC Setlist is a source-available setlist extension for Ableton Live. It turns Arrangement locators into an operator setlist, synchronized lyrics, tempo and click feedback, and guarded transport controls for rehearsals and live shows.

Network safety: Ableton RC Setlist serves browser controls on your local network. Use it only on a trusted LAN, keep the controller URL/token private, and never expose port 4444 directly to the public internet. See SECURITY.md.

Highlights

• Locator-driven songs and sections with [loop], [loop Nx], [stop], [next], [bpm N], [click], [click off], [skip] and [hidden] tags.
• Setlist and performance views for desktop, notebook, tablet and phone.
• Synchronized .lrc lyrics plus an in-browser timing and editing workflow.
• Guarded transport, quantization feedback and counted-loop handling.
• Per-profile ordering, lyrics and CSV export stored locally.
• Fullscreen stage mode with Screen Wake Lock when the browser supports it.
• English and Brazilian Portuguese interfaces in the same .ablx.
• No account, cloud sync, analytics or telemetry.

Requirements

• Ableton Live 12.4.5+ Suite (Beta) with Extensions support.
• AbletonOSC installed as a Live Control Surface for transport and Live Object Model operations.
• Node.js 24.16.0 or newer in the Node 24 LTS line only when developing from source. End users install the .ablx and do not need Node.js.

Windows is the validated release platform. macOS support remains experimental until this release is exercised on real macOS hardware.

Quick start

1. Install AbletonOSC from its upstream repository.
2. Download Ableton-RC-Setlist-0.4.0.ablx from the latest release.
3. Open the .ablx and approve installation in Live.
4. In Live, open Extensions > Ableton RC Setlist and start the server.
5. Use the panel URL or QR code to open /setlist or /performance.
6. Choose English or Português (Brasil) from the language menu.

The browser may show a warning for the per-install self-signed certificate. Accept it only when the address matches the host shown by Ableton RC Setlist on your trusted local network. Full instructions are in docs/INSTALL.md.

Locator format

Neon Signal [bpm 122] [click]
Neon Signal > Intro
Neon Signal > Chorus [loop 2x]
Neon Signal > Outro [stop]

Architecture

Ableton Live + AbletonOSC
          │ OSC 11000 / cooperative listener
          ▼
     Ableton RC Setlist extension
          │ local HTTP(S) + WebSocket :4444
          ├── /setlist       operator workspace
          └── /performance   stage display

The extension is local-first. The SDK-facing files sit at the edge; parser, state, transport policy, persistence and browser clients are testable through the public dependency gate.

Development

npm ci
npm run ci:public

The Ableton SDK and CLI are not redistributed in this source repository. Authorized developers can configure a complete build using vendor/README.md and docs/DEVELOPMENT.md.
