Kanochi Neko has a VCV and so does Teto? Though Kakoi doesn't still.
(I have a huge collection of around 500 banks, hah. ;; )
But seriously, around three years ago, maybe even just two and a half, VCV was an uncommon thing that mainly only JP banks had. Overseas was starting to catch on, but the otos back then were horrendous because I think people were still thinking CV. Even if someone was close, there was always something wrong (a popular rumor back then was you put the Overlap in the middle of drawn-out consonants like M and such, lolwat). I remember learning from really closely looking at Namine Ritsu's oto, and it made a lot more sense than CV did for me (back then there was only 1000 styles of CV, and there still kinda are). I made a tutorial, and even though it's bad and noobish and I need to redo it, I'm glad it helped move everyone forward.
Other people made tutorials before me, but they were either a bit incorrect or way too complicated (I remember Halo's custom VCV parameters tutorial, it only made some sense to me back then). I feel like I'm strutting too much though, it was the time when everyone was figuring it out and explaining it to one another, not just me.
now to understand these whippersnapper's cv vc stuff, english lite and things, full was hard enough to grasp
Yeah, VS4U is a resampler. Utalis is a plugin that, somehow when you plug in vocals it draws pitchbends and I really don't understand it well, you need to watch a tutorial to get it. Vocashifter (or was it Vocalshifter, maybe I've been typing it wrong) is a Japanese program that lets you see the pitchbends of a singer, and if you want transplant then and the dynamics onto another singer, though extensive editing it required to make it sound nice. This is how many UTAU/VOCALOID users make incredibly realistic singing. I'm pretty sure Mitchie M utilizes a device like this or Vocalistener (a VOCALOID only Utalis kinda thing) to do his stuff because it's even beyond Ciel-P level Vocaloid realism and her stuff actually is a VSQ.
There are a few UTAU screamo banks (Maiko, Teto's Rikimi, Ritsu's joke banks, C02, even Tree hah, and many others), but they've been rendered slightly moot by a new resampler called Utagrowl - it's brand new and there's a thread in Discussion about it. It's fantastic. Maiko and such still have their places as even Utagrowl I don't think can go that far, but now you don't need to make an append for your UTAU to achieve that type of vocal.
What's Vocascreamer? Sounds like a cool VST. I've mainly used Charsiesis, but I'm curious.
