(I know E-Capsule gave some recomendations, but I think it'd be wiser to get feedback from various users/ listeners.)
I tend to use Sonika and Oliver high around G3 (Oliver's voice works like that of a female's bank) likewise, Tonio sounds squeaky when he goes too high.
Now I've heard people use Oliver, Tonio, and Big Al pretty low, and they can sound great low, but what is generally preferred?
Same-wise with Sweet Ann, Sonika, and Prima. They can sound great High sometimes, but do you prefer them lower?
