- Settings: reference note duration slider (0.5-4s, default 1.5s) applies to
ear-training auto-play, sight-reading auto-play and the manual Play Note
button/keys alike.
- Settings: 'Wait for Silence' toggle holds the next reference note until the
mic detects the instrument has gone quiet (a still-ringing string masking
the next note was easy to miss). Safety cap of 8s so continuously
detectable room noise can't stall the app; without a mic it plays
immediately. The quiet state is a boolean dep (not the per-frame pitch
object) so the play timer isn't reset 60x/sec.
- Gate all live feedback (staff preview, readout, tuner) during speaker
playback: the mic inevitably hears the reference note and would briefly
leak the target in ear training. Virtual fretboard taps (explicit user
input) still display instantly.
