Macne Nana + Macne Petit -> Reason/Garagaband -> UTAU (note; they did not become official UTAU until their 2S releases) -> Vocaloid

That's the best we've seen so far in terms of engine skipping overall, CeVIO's engine is a bit worst then Vocaloids in terms of engine noise... So aside from one or two phonetic differences, the results overall likely will sound worst. Same thing happens with the Japanese vocaloids as it is. With Nana and Petit, the change was beneficial as each jump improved things in some little way, though the Vocaloid jump is the closet one to sound as they intended in Reason and Garage band. Jumping engines can make a vocal sound different.

I don't think its fishy as technically... Yukari, Akari and Zunko are on two different engines, one for speech and one for singing, namely the speech is Voiceroid.
