Gameplay Settings

Left-handed mode
Invert frets on the note highway for left-handed players.
Default arrangement
Which arrangement loads first when you open a song.
Arrangement routes
How arrangement variants are labelled across the app.
A/V sync offset: 0 ms
Positive = audio plays ahead of visual notes; raise to catch the highway up. Adjust live with the [ and ] keys (Shift for ±50 ms). Auto-saves.
Note highway speed: 100%
Master difficulty — lower simplifies the chart (fewer notes); 100% plays the full arrangement.
Miss penalty Not yet active
How harshly missed notes are scored. Saved now; scoring wiring lands in a later release.
Countdown before song
Play a four-beat count-in before a song starts so you can get ready.
Fail behavior Not yet active
What happens when you fail a section. Saved now; gameplay wiring lands in a later release.
Autoplay & auto-exit
Start songs/lessons automatically and return to the menu when the score screen closes.
Show “Up Next”
Display the upcoming-section pill in the top-right of the player during playback.
Ask before leaving a song
Confirm before Escape (or the player’s ✕) exits a song. Off by default — Escape leaves instantly. With it on, a confirm appears; Space, Enter, or “Leave” exits, while Escape dismisses it.

Accessibility

Interface size
Make the app’s menus, buttons and text larger or smaller. This changes the app interface — not the notes on the note highway (set those under Graphics). On desktop you can also press Ctrl + / Ctrl − to zoom the whole window.

Larger sizes are recommended for large or high-resolution displays.

Fine-tune size
100%

Audio Settings

Live guitar tone source
Choose External/Spark if your guitar tone comes from hardware like Spark LIVE. fee[dB]ack still scores your playing but won't warn that no internal amp tone is loaded.
Demucs server (for stem separation)
Optional. Run feedBack-demucs-server on a GPU machine to offload stem splitting and avoid resource exhaustion on the host.

Graphics Settings

Keyboard Shortcuts

Progression Settings

Plugins

Plugin updates
Check installed plugins for newer versions.

System

Library folder path
The folder fee[dB]ack scans for your song library.
Library
Rescan checks for new songs. Full Rescan clears the cache and re-imports everything.
Metadata matching
Matches your charts against MusicBrainz in the background to tidy names, years and genres — display only, your files are never modified. Matches at or above the confidence level apply automatically; the rest wait in the library's review queue. Turning this off never disables manual match fixes.
Sources
Auto-apply
What a confident match may fill in on its own — matches you confirm in the review queue always apply in full.
Artist pages
A page for every artist in your library — their songs, albums and your practice progress, built entirely from your local collection. External links (official site, tour dates, videos, social) come from one MusicBrainz lookup per matched artist and always open in your browser — nothing plays in-app, and they stay off until you opt in.
Backup
Export bundles server config, browser preferences, and opted-in plugin data into one JSON file. Import overwrites current settings and reloads.
Diagnostics
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.
