XD I wrote it right after I woke up, so I didn't really process your post correctly.
Generally, all I do to a CV UST to make it VCV is clear overlap and preutterance and STP if it is there (select all, right click, last option. Mash the clear button and click in the STP box and press space.)
If the UST is in Mode 1, you have to switch to Mode 2 and either string it so that it just sounds normal, or you have to start over and copy the pitchbends.
Copying pitchbends is easy, but time consuming. I would suggest just sticking to USTs in Mode 2.
Stringing the notes is VERY IMPORTANT in VCV! Without it, it will sound very icky and robotic.
Envelope is also important. If the envelope is set a certain way, it will sound icky and junk.
Well, you want to make sure that none of the pitchbends are too drastic (Don't want them like |, you want them more like /.) and that the envelope is like /---\ instead of |----|.
It's a bad example, but I'm too lazy to get screen shots.
You may want to just experiment to find how to make the vocals flow the best.
Also, having OTOs done right is another HUGE requirement.
Don't just move the blue around to make it fit. Do not use ratios or anything like that.
Just make sure that there is at least .1 second of preceding vowel, the green is where the vowel is tapering off into consonant, the red is between the consonant and the second vowel, the pink is after the consonant and includes some of the second vowel, and the last blue cuts off the rest.
You do have to edit the OTO I gave you... But stealing OTOs makes VCV so much easier!
And, I do not see how anyone who isn't professionally trained could do Ritsu's list without getting light headed and mispronouncing things XD!
