Overview

Represents a meter change at a specific musical position

MeterEvent marks a point in a musical timeline where the meter (time signature) changes. This is essential for properly calculating musical positions and normalizing bar:beat:tick:subtick values.

Examples:

Creating a meter change to 3/4 at bar 5

position = HeadMusic::Time::MusicalPosition.new(5, 1, 0, 0)
meter = HeadMusic::Rudiment::Meter.get("3/4")
event = HeadMusic::Time::MeterEvent.new(position, meter)

With common time

position = HeadMusic::Time::MusicalPosition.new(1, 1, 0, 0)
meter = HeadMusic::Rudiment::Meter.common_time
event = HeadMusic::Time::MeterEvent.new(position, meter)
