^You also get problems when you go low so its also the reverse.

It works the most against a vocaloid when the engine is forced to improvise. The samples used in vocaloid are built to cover a certain range, when you are not within that range, the samples are substituted by the engine itself.

The "_0" sound is almost impossible to reproduce naturally by the voclaist, Vocaloid is improvising on this phonetic. Since V2's in V3 can recreate this sound and they never had it in the first place, this is the easiest example of finding Vocaloid doing something it has to work out for itself without a library sound to use.
