- Metronome widget: BPM/slider row and pendulum always visible (dimmed
when off); the toggle gates sound + animation only. BPM/Timer mode
switch restored for single-note auto-advance.
- Giuliani right-hand figures as arpeggio patterns: p-i-m, p-i-m-a,
p-a-m-i, m-a-m-i, a-m-i — cycle [root, third, fifth, octave] per figure
with octave register shift per repetition (120-studies feel).
- Pool fix: fretted instruments without active filters now get the full
0-12 fretboard in ALL modes (legacy difficulty ranges no longer clamp
the pool since the Note Set dropdown was removed).
- Tests 174/174.
- Strings filter: per-string toggle buttons (replaces fret-window-only
semantics as a third 'limits notes' control); combines with fret window
and key filter in targetPool (fretted instruments).
- Key sync checkbox: display key signature can follow the target key
(major/minor mapping), default off — both remain independently settable.
- LiveNoteStaff: optional fixed clef — guitar/bass now keep their usual
clef instead of flipping at middle C; octave markers handle range.
- Unified metronome widget (MetronomeWidget) with animated linear pendulum
synced to the audible click; shown in ALL modes next to the tuner.
Phrase BPM now reads from settings.rhythm.bpm (single source); the
phrase-local BPM control was removed from the setup panel.
- Tests: 160/160; tsc + eslint clean; build ok.
- New shared PracticeFilter settings (keyTonic/keyMode/fretWindow), persisted
via AppSettings.practice, defaults off (behavior unchanged).
- music/targetPool.ts: single source for the effective target pool —
base playable range ∩ fret window ∩ key/mode pitch classes (9 modes incl.
pentatonic, same scale machinery as Phrase Mode).
- useGameLogic now builds validNotes via computeTargetPool.
- TargetNoteControls component (key on/off + tonic/mode, fret window on/off +
min/max) rendered in Controls for all game modes; key is independent of the
displayed key signature.
- Phrase Mode binds its key/fret-window setup to the same shared filter
(read/write mirror) and drops the duplicate controls in its setup panel.
- Tests: targetPool.test.ts (7 cases); suite 156/156 green, build ok.
