Aye, if you jump from one note to 4 notes higher, its been pretty normal to get warp sounds since V2, in V1 it was barely anything human-like at times. Going from the lowest note to the highest note in a Vocaloids recommended range along gives 0.4 seconds of awful results, depending on the range it can get worst and vocal type... Sonika sounds better for example then Big Al. Though some Vocaloids are noted for particularly having sweet spots where it doesn't happen, or points where its really bad. I think Cul is such a case.

On a different note, since you don't have Vocaloid Viper.

A lot of the people who pick up Vocaloid and ignore the vocal ranges presume because vocals like Piko *can* produce low results, that those results outside his recommended range are good. It is the same for all Vocaloids. They don't understand tonal collapse occurs outside the vocal ranges often or that the Vocaloids loose their abilities to sound natural and end up with a forced tone or other problems. You can't go outside a Vocaloids normal range unless you know what your doing and can repair the major tone collapse or bugs like pronunciation issues without it. There is also the issue of what tempo works for a Vocaloid best in their recommended range changes once you leave. Meaning the result is the Vocaloids samples can get muddled and slur or a few times be known to skip sounds, though that may have been addressed over time. But definately, slurring in more noticeable outside a vocaloids recommended vocal range at tempos they would normally be able to handle.
