Thank you, I was frightened nobody would understand I was aying how they use Luka for experimentation all the time.

After V4x Luka entered my least favourite vocaloids, though i not at the bottom like Len, Rin and Miku. For me, the biggest issue with V4x is we waited about 6 years for Luka Append and each time CFM ended up for one reason or another not meeting a deadline. So they lead with the 1 member of the CV series who never saw an Append.

Maybe they felt she was more of a "clean slate" due to no previous version Append to compare with, but the result is a mess. I had taken in the last 6 months to saying the package basically has 3 vocals in it which were lazy reprinted to make 6, because even the English had a bit of laziness to it since all they did was reprint the one with a little more breath... You can tell by the fact the two vocals have no just the same flaws but exactly the same flaws, phonetically and their wavelengths are similar in behaviour.

Funny thing about Sonika is she is their only processed vocal and was designed to mimic how the Japanese were making their vocaloids. She too was also an experimentation, one that didn't pay off. The process brought out and created a lot more bugs then a normal Vocaloid would and thats not even touching some the phonetic data,this is just how badly her samples suffered.

They've not done it with any of their other vocaloids, except the odd repitch, which has to often occur with any vocaloid as Vocaloid itself often changes the pitch of samples. I've had to point this out to people over the last year because there are some who try and pin some of the issues with Ruby on So and PowerFX nd claim Vocaloid has no effect on the vocal... This was countered by Misha who said her raw vocals are not nasally and the nasal tone was either gained in the process of developing the vocal as a result of slicing and combining sounds, or by Vocaloid itself... The latter being more likely as some vocals have slightly changed tone when imported into newer engines. V1 was the worst offender of this and its vocals were really badly effected.
