————- VCV Rec-Lists ————-

First things First.
you need to know what kind of list you are recording with.
there are lists
2モーラ all the way to 8モーラ (or even higher)
the number is the number of sounds that are in the list.
the most commonly used List is 7モーラ(MOORA):

2モーラ かか (ka ka)
3モーラ かかけ (ka ka ke)
4モーラ かかけき (ka ka ke ki)
5モーラ かかけきか (ka ka ke ki ka)
6モーラ かかけきかき (ka ka ke ki ka ki)
7モーラ かかけきかきけ (ka ka ke ki ka ki ke)
8モーラ かかけきかきけく (ka ka ke ki ka ki ke ku)

for some people, 7モーラ might be too long.
so there are other’s to choose from.
but the smaller the number of Sounds the more recordings you will have to do.

You can get Lists from all over the place:
Yoru’s Rec-Lists: (Posted on YouTube Channel “YoruIkusane”)
N.H.P Website: http://utaunhp.info/ (Japanese Only)
UTAU’s Blog: http://utau2008.blog47.fc2.com/ (Japanese Only)

There is also a Triphonic List Generator (Made by まる@Loop):
↑ the Problem with this is there is no Romanized (or English) version to this list.
↑ Also the sounds are in random order. so there is no set pattern to the recording which could be difficult to record without some error.

——— Recording Triphones ———

This Tutorial will tell you about Recording with one of the following lists:

Before you record. you need to know how the sound’s should look:
1. You should have .5 ~ 1 sec of silence before and after the Recording.
ー If you like you can have a breath in between the .5 ~ 1 sec before you actually start recording.
2. You’d want your recordings to be about this long:
5モーラ → 3 ~ 5 Seconds.
6モーラ → 4 ~ 6 Seconds.
7モーラ → 5 ~ 7 Seconds
3. You want to keep a consistent beat in your mind while you Record so everything is
around the same size and shape.


————bre-|KA KA KE KI KA KI KE|————–
| .5 ~ 1 sec | 5 ~ 7 seconds | .5 ~ 1 sec |


Now that you know how it should Look its time to know how it should sound.

You need to keep the sounds as close sounding as you can.
You don’t want a POWERFULL Recoding mixing in with a WHISPERY recording.

You also want to think of Triphones as normal conversation. so you don’t want to record like
Ka~♪ *waits a sec* Ka~♪ *waits a sec* Ke~♪ *waits a sec* Ki~♪ *waits a sec*
Ka~♪ *waits a sec* Ki~♪ *waits a sec* Ke~♪

↑↑↑ BIG NO NO! ↑↑↑

Big No No #2 is exaggerating your consonants, you should keep them at a normal lenght (do not make them longer than you normally say them)
Example: ssssssssssssssssssssAAAAAAAAAAAA

Another thing you should listen for is Stuttering. It might happen. and if you do it. your UTAU
Will sound like it does.

—————- oto.ini —————–


======== By Hand ========

– The alias should look like → “Previous Vowel” “Space” “VC sound”:
  - Example: Ka_ka_ki_ka_ku_ke_ka → “a ka”, “a ki”
  - Example (In Jap) かかきかくけか → “a か”, “a き”
– THERE ARE 2 TYPES OF SPACES “ ”(Japanese) and ” “(Romaji) MAKE SURE YOU
– If there is no Previous Vowel then put a – in its place
  - Example: ka_ka_ki_ka_ku_ke_ka → “- ka”
  - Example(Jap): かかきかくけか → “- か”
– There are 8 letters that need to go before the CV(Like “Ka” “Sa” “Ta” “Na”) Sound.

– CV
a CV
i CV
u CV
e CV
o CV
n CV
V –

  - The “- CV” and the “V -” can be important.
– the way /I/ see the “-” symbol in this case is the breath in/out sound.

Constant (Pink Area):
– Put after 2nd Vowel (the 2nd V in VCV)
  - If the sound is like “Kya” or “Sua” put over the extending Vowel (i.e. the “a” sound)
– if you put it over the “y” or the “u” that will be extended in the song and not the “a” (depending on the length of the note)

Cutoff (Right Blue Area):
– Depending on the beat you recorded too it may vary.
– use a negative value Like -700 or -100
– -500 ~ -700msec’s will be a good value if your recording is 4 ~ 7 secs long.

Offset (Left Blue Area):
– Because you made the Cutoff a negative number, where ever you move this you will have (if using -700 as the cutoff) 700msec’s of sound.
– 1000msec’s = 1 Second
– play with this till the Consonant is in the VERY MIDDLE of the 2 blue lines (the Offset and Cutoff)
  - You can move the Cutoff value if the next consonant is poking though (you don’t want VCVC.)
– If you do this then the Cutoff will turn into a Positive value and will stay at that point till you choose to move it)

Preutt. (Red Bar):
– Put this RIGHT AFTER THE consonant sound
  -Example: if you are working on the sound “a ka” you want the Preutt here → “ k|a ”

Overlap (Green):
  - If the Preutt is 300 then the Overlap MUST be set to 100.
  - You can put the Overlap where the between the Vowel and Cons → “ a|k ” BUT YOU’D BE WRONG!

======== setParam ========

The reason why i put setParam last is because for future reference you might need to know
How to do a small problem by hand.
  Download Page → http://freett.com/nwp8861/soft/setParam/index.html
  English Patch (By Mianaito) → http://www.youtube.com/user/mianaito
under [OREMO] Instructions are also on this page.

1. Open up setParam and select the Voice Bank Folder.
2. Select Don’t Load.
3. Got to Options
  >When Left Blank is Modified
    >Other parameters are modified accordingly to keep relative positions.
4. Go to Tools
  > Automatic Voice Parameters Estimation (VCV / Continuous Utterance.)
    >Push “Initialise Parameters according to Recording Tempo” UNLESS YOU KNOW THE TEMPO IN WHICH YOU RECORD TOO.
– You might have to mess with the tempo a little depending on how you recorded
      >In the Area with all Japanese is where you tell setParam how many copies of sounds you want it to keep.
    - you will most likely have more than 10 “i” and “n” sounds and maybe copies of other sounds.
Example: you may have more than 1 “i Ki”, “n a” sounds.
    - If you want it to get rid of ALL the duplicates select the option “付ける” and make the Number in the box “0”
    - If you want a maximum of 2 duplicate sounds put “2” in the box with the “付ける” selected. This will keep a max of 2 duplicate sounds if one appears. and will give the 2nd one a “2” after its name.
Example: you can have a “a ki” and a “a ki2” in your oto
    - If you keep “”付けない” selected it will keep all the Duplicates with numbering them.
>Push “Generate Params”
5. The controls for setParam are as followed:
F1: Offset (Left Green Area)
F2: Overlap (Green Bar)
F3: Preutt. (Red Bar)
F4: Constant (Lower Blue Area)
F5: Cutoff (Right Yellow Area)
F6: Moves to the next sound in the oto.ini
F7: Moves to the previous sound in the oto.ini
F8: Play’s the Sound in-between the Offset and the Cutoff
Space: Play’s the whole sound
  - Moves to the next(down) or previous(up) sound in the oto.ini
  - while pushing CTRL will Zoom in/out of the sound.
Right Click:
  - When on top of the Recoding, will show you the options that can be shown in the window
Left Click:
  - Nothing (form what I’ve tried)
6. You might want to open up the Spectrum by going to “Show” or “CTRL + Right Click”-ing. For better results.
7. Saving. CTRL + S or File>Save will do.

—————- Ending —————–

All in all, you the more you record and Play with VCV the more you’ll understand it.

I hope this tutorial helped you at all

Mn, Thank you for this Yoru! Sure to be useful (even if there are a few small details that I’m not quite sure I agree with, they’re not major).
