Module chart_process 

Chart Processor

Unified Y coordinate definition:

• In the default 4/4 time signature, the length of “one measure” is 1.
• BMS: When the section length is the default value, each Track has a length of 1. The section length comes from the #XXX02:V message per measure, where V represents the multiple of the default length (e.g., #00302:0.5 means the 3rd measure has half the default length). Cumulative y is linearly converted with this multiple.
• BMSON: info.resolution is the number of pulses corresponding to a quarter note (1/4), so one measure length is 4 * resolution pulses; all position y is normalized to measure units through pulses / (4 * resolution).
• Speed (default 1.0): Only affects display coordinates (e.g., visible_notes distance_to_hit), that is, scales the y difference proportionally; does not change time progression and BPM values, nor the actual duration of that measure.
