It goes against the end user agreement with both Yamaha and the studios in the two vocals.

You can do this in private but you are not suppose to publish result and this is what their doing when they upload onto youtube and soundcloud. You can still make ad revenue money too so its not like your not doing it with no chance of a come back.

XSY groups are the limits of what your allowed, I've seen language ones too but they only work when the samples are the same for both languages, you get really bad results for much of the time. For English they share only 40% sounds with Japanese and even then they have far more samples involved. Then there is a Big Al one out there (V2s aren't able to XSY without modding and their pretty LQ) with a Vocaloid who share none of the range with each other and the singing results where neither suppose the range are terrible.

Outside of mixing the same provider results, XSY can give LQ results. Though some deny this its sadly confirmed. This is why Megpoid V4s pairs where set up as they were, Each pair gave a HQ XSY result. But mixing the vocals outside of the pairings, even if with other Megpoid voicebanks, started to see loss of quality. Mix two very different vocals and you might as well forget about quality.
