I'm using Ms. Atia Soft, a VCV Japanese bank developed by Ms. Valentine. She won't sing any notes at C4 and below, but can sing everything else perfectly fine. I've tried it with two separate USTs. Her recorded pitches are F#4, E5, C#4, and B5, but unless I'm an idiot, it should still sing C4 and under. Her other voice banks also stop at C#4, but they sing perfectly fine. I'd appreciate some help!
