YuE2 covers frequently break: one mistimed word derails the whole song's lyrics

Gyramuur · reddit · 2026-09-17

A user reports open-source music model YuE2 works fine for text-to-audio in ComfyUI but fails often on covers: lyrics get wrong despite being explicitly written, or a single word sung early derails the timing of the rest of the song, sometimes degrading into gibberish or omitting entire bars.

They're unsure whether the bug lies in the model, ComfyUI, or sheetsage transcription, and are asking for workarounds.
