elementsCarryVoiceNumber property
bool
get
elementsCarryVoiceNumber
True when every Note/Chord in this voice already declares
voice == number.
A null voice does not count as carrying the number, not even for
voice 1: it only means "unassigned". Returns true for a voice that
contains no notes or chords.
Implementation
bool get elementsCarryVoiceNumber => validate().isEmpty;
