The problem happens with only Japanese VCV banks. I haven't tried with CV-VC because I never use them in the first place. It sings samples that are like, for example, -か, か, or samples completely in romaji. It plays CV Japanese and CVVC English normally. If the note is like "a か" , or any mix of romaji and hiragana, it doesn't play. I tried with multiple voicebanks, multiple resamplers and multiple usts, and it never works. All the voicebanks have the samples and the oto.ini. When I try to play the notes, the resamplers take their time to render them, which means that the computer does recognize that the notes are there, but they just won't play.
