Functions

Detailed Description

Exact written durations, independent of playback time.

MCC::NoteValue records a power-of-two note base and its augmentation dots. MCC::Note combines that exact value with a spelling-preserving MCC::Pitch. MCC::Meter preserves a written time signature and derives simple or compound beats without guessing irregular groupings. MCC::RhythmPattern records which steps of a cyclic grid are onsets, in the box and interonset-interval notations of Toussaint's The Geometry of Musical Rhythm. None depends on tempo, clocks, PPQN or MIDI.

Function Documentation

HasSameMeasureDuration()

bool MCC::HasSameMeasureDuration ( Meter a, Meter b )

constexprnoexcept

Returns true when two valid meters span the same whole-note length.

Written identity remains distinct: 3/4 != 6/8, but both have the same measure duration.
