Treating authorship, phoneme placement, and rendered pitch as one editing surface obscures cause and result. The three modes separate those concerns while preserving one vocal part.
Plan records intent
Plan contains the durable score objects: Notes, lyrics, pronunciation, slurs, articulations, expression, and voice assignment. An edit belongs here when it changes what should be sung.
Timing records placement
Timing shows how planned phones occupy musical time. A Timing Nudge changes a phone boundary without changing the written Note. An edit belongs here when the words are correct but an onset sounds early or late.
Pitch records the result
Pitch displays the continuous Pitch Line from the latest bake. Note expression and processor parameters shape the next result. An edit belongs here when the score and diction are correct but the sung contour requires revision.
One evaluation loop
The modes are not separate pipelines. They are views of the same vocal part: author the Plan, evaluate Timing, evaluate Pitch, then bake and listen again. The separation keeps each correction close to the noun it changes.
