Library Folder Path
Left-handed (invert frets on the note highway)
Autoplay & auto-exit (start songs/lessons automatically and return to the menu when the score screen closes)
Default Arrangement
Arrangement Names
A/V Sync Offset: 0 ms

Positive = audio plays ahead of visual notes; raise this value to catch the highway up. Adjust live with the [ and ] keys (Shift for ±50 ms). Auto-saves on every change.

Demucs Server (for stem separation)

Optional. Run feedBack-demucs-server on a machine with a GPU to offload stem splitting and avoid resource exhaustion on the host running FeedBack.

Library

Rescan checks for new songs. Full Rescan clears the cache and re-imports everything.

Backup

Export bundles server config, browser preferences, and opted-in plugin data into one JSON file. Import overwrites current settings and reloads.

Diagnostics
System info Hardware (CPU/GPU/RAM) Server logs (last 5 MB) Browser console + errors Plugin diagnostics Redact paths & song names

Bundles server logs, hardware info, plugin inventory, and the browser console transcript into one zip for bug reports. Redaction strips DLC paths, song filenames, and IP addresses by default. Attach to GitHub issues; AI agents can parse the included `manifest.json`.
