its usually the range the vocaloid was built for and what range is therefore most natural for the, it also produces the highest quality. The samples were recorded for this range.

The further you go from this range, more more bugs normally become apparent. this is because this is when VOCALOID itself has to think about improvising more and more. You can get a lot odf distortion when you go too far from the recommended range/tempo.

You can ignore the recommended range/tempo if your skills are good enough to work around the issues presented by this. Some also like this effect and seek it on purpose.
