Have you used XSY with a v4 before? XSY works best for vocaloids that where meant to XSY so V3 vocaloids have varying results. I personally think XSY banks and appends are better than voice banks in another language, because no bilingual vocaloid yet have masters both of their language. All of the vocaloids that are in a language non- native to the voice provider all have accents and pronunciation errors. Using your logic "right tool for the right job"  they have no reason to be used because there are native vocaloid in that language. They take away from development time where it could be used to perfect and expand the naive voice bank ex.(SeeU, Yohioloid, Macne Nana). Xsy is a usefull tool because you can get realistic and natural variation which couldn't be done before. Now you can have subtle phonetic variation so it's [a] phoneme isn't the same all the time. You can also use XSY to make realistic doubled vocals.I have used gumi v4 demo and have to say she XSY perfectly. Gumi v4 is the best v4 update yet. It has the original 5 Gumi voice banks for the people who want gumi to sound like how she was in her previous releases and then 5 new voice banks using new recordings to blend with original gumi but can also stand on it's own. When you compare it to other v4 releases this has both of best worlds.
