### 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.

### 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.

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.

Scoreboard
Venue Motion
Venue Mood FX

Venue uses 3D Highway with a small-club stage scene behind the fretboard.

Venue scene assets could not load — playing as plain 3D Highway. Check static/assets/venue/themes/small-club/.

Use Venue for the reactive crowd/stage version.

Venue Motion adds subtle background parallax only — the note highway stays fixed. Mood FX controls performance tint overlays.

Guitar tone

External/Spark: hardware supplies tone; no internal amp warning.
