[ethlyn]

is there a limit to how long a note can be? i am trying to extend a note past 4 bars but it does not let me. i am very new to utau so i dont know how to fix this

You can add another note with the same vowel as the previous note. For example, to extend か you'd create a new note with the lyric あ.
