Lightbridge

Saving Your Work

Lightbridge stores your work in show files — a single file that contains everything about your current project.

Show files

A show file saves:

  • All performance sets (chains, parameters, modulations, palettes)
  • Controller profiles and MIDI bindings
  • Output configuration and projection mapping
  • Action buttons and pad bindings

New with Cmd+N. Open with Cmd+O. Save with Cmd+S. Save As with Cmd+Shift+S to create a copy.

Auto-save sessions

Lightbridge automatically saves your work to a session file on every change, debounced by 500 ms so rapid editing doesn’t flood the disk. If the app closes unexpectedly, your most recent state is preserved — you won’t lose more than half a second of work.

Sessions are stored in the app’s user data directory under sessions/. On next launch, Lightbridge restores from the most recent session automatically.

Presets

Presets save the parameter state of a single source or effect so you can reuse it later:

  1. Right-click a node in the chain.
  2. Choose Save Preset and give it a name.
  3. Load it later on any node of the same type.

Presets are stored separately from show files — they’re available across all your projects.

Tips

  • Session auto-save covers you during a show — you rarely need to hit Cmd+S mid-gig. Manual saves still work, but the session file is kept fresh automatically.
  • Name your shows descriptively — “2024-festival-mainstage” is better than “Untitled”.
  • Show files are JSON — they’re small, portable, and can be version-controlled if you want.
  • Performance Sets — sets are stored inside the show file; one show can hold many sets.
  • Performing Live — how auto-save and hold mode fit into a gig workflow.
