Hello. I'm new to UTAU, and I like it so far. But when my UTAU tries to sing "shu", only a thumping noise comes out. This has happened to me before, but resetting the 周波数 doesn't work like it did there. I checked, the file is there, and it even played for me when I clicked on 原音の設定 , but he just won't sing. He also suddenly can't sing a note he did sing fine before after I changed the oto since it sounded wrong. Help?
