Here a list of Voicebanks that I found good quality to use. I may Find more in the future. so check this if you want. 
(this is just my opinion on voicebank choice ok? everyone have they own likes.)

Voicebank That I Reccomend (myopinon...Ok?)

USTs to Try/Have 3

GUESS WHO I'M BRINGING BACK, AND IS FINALLY FINISHED!!

Art for the song will be added once I get some done.

Here's Akihiro Utaiji's ACT 3/REBOOT bank! Last minute VCV parts have been added, and are used in this cover!


UST: Pandamo-nium
Song: Minato-p
UTAU: Akihiro Utaiji

He really doesn't have a proper usage clause, as long as you don't claim his bank as your own.

Long time no see.
I write ORIGAMI-I and it is ORGAMI.

I tried to record E4CV to commemorate the long time.

It's a murmuring CV.
I imaged the drizzle and recorded it.

Also includes VCV of vowel and breath and humming.
BPM 100 one beat CV. So long tone is not very good.
Please use long vowels.
Aliases are "あL" and "a L".
There is "i <" as an infinite variety.

UTAU Cover + VB /// weekday (cloudy) /// ORIGAMI - I

Song: Yuyoyuppe
UST: 混乱-P

The fellow who made this UST is a genius, and there is no way I can ever reproduce whatever they mixed from it. ( ; v; )

But that aside, I’m super happy to say that Tsux’s CVVC is finally done and ready to be released for real~! Not to mention, I can reveal that the voicebank will now go by the name of XANADU.

Why? I dunno, I picked the name because it sounded vast. ^^;

As I’ll state in the Release Video, this voicebank contains three voice types: Normal (Default), ASTRAL Z (Soft), and CATHARSIS X (Loud), the latter two used by adding a Suffix to the end of each sound.

ASTRAL Z= Add “_Z” after a sound. (eg: “あ_Z”)
CATHARSIS X= Add “_X” after a sound. (eg: “あ_X”)

I hoped to try to use each set as best I could in this cover, so you should be able to hear and/or discern each one when listening.

Once again, I’m very thankful to @CyberneticEden for helping me fix and redo the oto’s, because I am a boober who didn’t know what she was doing at first! I would have been lost without them.

So to stop myself, here be another new voicebank for Tsux.
I can’t believe she’s grown so much since her first CV bank, here’s to more progress in the future!

notes I forgot in the readme

- some of the lyrics did not match at all what was being sung, im sorry if I got these wrong

- the growl used the MG flag, not vibrato or some magic defoko growl sample, so keep that in mind.

- either im paranoid or some parts may be off time. I am not sure why. its easily fixed in mixing
