pub const VOICES_CONVENTION: &str = "each note counts from its onset to its note-off knee, or to \
25 ms before its end without one, so a release tail holds no voice, and a held part stops at the stem end; pitches within 60 cents form \
one voice; max_polyphony is the most voices that have started by any onset and are held 50 ms after \
it, mono when that is 1; mean_polyphony is the mean count over the time any note is held, so short \
overlaps can lift it above max_polyphony; null without notes, or when no note holds a sounding part";Expand description
