("JP" "EN" means they have voices in Japanese or English language.)
How do you think about CeVIO's voice quality?
CeVIO uses HMM parametric system to generate the voice.
That may decay smoothness a little, but that makes the voice more natural and animated in the aspect of ways of pronouncing and singing.
Does it have English voices?
In June 29, 2018, the first CeVIO English song voice "IA ENGLISH C -ARIA ON THE PLANETES-" is released.
It has two type of voices, "Natural" and "Powerful".
The official site is here.
Does it have English interface?
CeVIO has English interface.
The interface language depends on your Windows settings, though you can change it at the toolbar →「ツール(T)」→「オプション(O)」→「表示言語」and pull down「英語」→「OK」button→ close and relaunch CeVIO.
2. How to use trial version

You can use the trial version for free for 30 days.
The characters you can use are Sasara (song&talk), Tsuzumi (talk) and Takahashi (talk).
You can also use HAL-O-ROID (song) for free while you can use song editor.
The contents of the trial version is same as the product version, except for the limitation of period and no function of exporting to wav file.

3. How to buy and install product version
How can I buy CeVIO product version?
You can buy the product version online with credit card or other payments.
The tutorial is here or here (made by Uchuu).
When you bought one, don't forget to back up your serial number outside of your computer!
How can I buy CeVIO physical package version?
Probably you can also order physical package version (below) through amazon.jp.
For example, the starter pack for Sasara song voice is basically 8,640 JP yen.
If you have already bought song editor, you can use HAL-O-ROID for free (without registration).
If you once bought starter pack (editor + voice) and are going to add some voice, you need to buy new voice only (a lot cheaper than starter pack).
Each price of CeVIO products is here (please read with translation).
2. Buy the CeVIO product
Buy the product as above.
Check the serial number (or called "licence key"), which is informed through the e-mail after the payment, or printed inside the package. It is like "aBCd1-2EF3g-H4IjK-L5mN6".
3. Fill in the serial number of editor
Launch CeVIO and wait for the window as below (if you are using the trial version, launch CeVIO and click 「ヘルプ(H)」→「ライセンス認証(L)」).
Select 「ライセンス認証を行う」, fill in the serial number and your mail address as below.

Get the voice installer, which can be get through the e-mail after the payment, or the DVD of the package.

Launch CeVIO and click 「ヘルプ(H)」→「ライセンス認証(L)」.
Fill in the serial number of each voice.
Also the voices are sometimes updated, so check here (as below) so as you have the newest voice.
I think it is better to update it (when you aren't focusing on work with it), as newest version often has solved the problems or has new useful functions.
I want to transfer CeVIO to my new computer.
1 licence (serial number) corresponds to 1 computer.
If you want to transfer CeVIO to your new(other) computer, you have only to install CeVIO with the new computer and enter your serial number. You don't need deactivation.
Keep in mind if you install it to different computers more than 4 times, you might need re-authenticate (re-register) to launch it.

Your computer needs to be online when you first launch CeVIO product version and every 365 days.
Your computer needs to be online everytime when you launch CeVIO trial version.
If you get the dialog box containing "ライセンス再認証", you need to ask CeVIO official to re-authenticate (re-register) your computer from here. You need to fill in "メールアドレス" the mail address you entered when you first launched CeVIO. As for "お問い合わせの種別", choose "ライセンス再認証が表示された".

【IA & ONE】ARIA STATION「ONE先生のIA ENGLISH C講座 ＃1」（18/7/6）【English Subtitle】

users' tutorials in English
CeVIO Basics/Tutorial - Singing by Rinshuu
CeVIO Creative Studio S Tutorial (The Basics) by Zefurry
How can I import MIDI/ust/vsq files?
MIDI: drag & drop the MIDI file to CeVIO's upper area.
ust: convert it to smf(MIDI) by UTAU, or convert ust to ccs by UtaFormatix
vsq or vsqx or vpr: convert it to ccs by UtaFormatix, or convert it to smf(MIDI) by UTAU
How can I export MIDI files?
Choose the red track (in the upper window), right-click on it and select "エクスポート" → "MIDIの書き出し".
How can I enter lyrics?
You can enter lyrics directly or by phonemes.
enter by lyrics
Click NOR button and doubleclick the note, and you can enter the lyrics. To move to next note, just press TAB key.
You can enter words of several syllables like [twin][-kle].
To enter 1 vowel in several notes, enter "-" in other than the first note (like [a][-maz][-ing][-][-]). The consonants following that vowel (like [ng]) automatically laid out in the last note.
enter by phonemes
To enter phonemes directly (with alphabets), rightclick the piano-roll and click "音素で歌詞入力(P)". Phoneme palette rises up and you can directly enter phonemes through the palette or your keyboard.
CeVIO uses (for English voices) phonetic signs called "Arpabet", widely used in voice synthesis researches. Arpabet is written in 1 or 2 (or 3) alphabets for 1 phoneme, so you can enter it directly with your keyboard. The conversion table is here (Wikipedia).
You can enter 1 or several phonemes in 1 note. You can even enter 1 consonant only, or several vowels in 1 note.
To enter plural phonemes in 1 note, put in “,” between them (when entering on "音素で歌詞入力(P)” mode).
What's TMG?
TMG = timing of phonemes.
When you want to change the timing of a whole phoneme, first click the pen tool and drag the dark gray zone at the bottom of the piano-roll to left/right.
Each phoneme is composed of five parts. Each part corresponds to how humans produce sounds and open/close the mouth. When you want to change the timing of a part of a phoneme, drag the each line to left/right.
Click TMG button and click the font of VOL, and you can easily see how the volume (and other parameters) changes in response to TMG.
What's VIA/VIF?
VIA = vibration amplitude.
VIF = vibration frequency. The bigger, the more frequent vibrato gets.
Click PIT button and click the font of VIA/VIF, and the pale vibrato line appears on pitch line.
If you want to generate vibrato on the area naturally has no vibrato, you need to draw both VIA AND VIF on the area.
I want to turn off the automatic vibrato to draw it manually.
If you want to turn it off in a part of a track Open VIA, and draw the line on the bottom (0.00cent) at the part.
If you want to turn it off in the whole track Right-click the piano roll, and click 「調整モード(M)」→「ビブラート無効(V)」.
I think Sasara sings too choppy.
Edit TMG(timing) parameter between vowels or "ん(N)" as below.
2. voice quality: look at the link.
Default is 50 (or +0.00). The higher it is, the more mature the voice gets.
http://guide2.project-cevio.com/songtrack/song06
It works in the whole track. If you want to change it in some notes, you can copy the track, change it and put them together on DAW.
3. use TMG
CeVIO voices change its quality in each area of "TMG(timing)".
http://guide2.project-cevio.com/songtrack/song07
If you want breathy voice in some notes, the last TMG area of each notes often has breathy quality, so you can make it wide.
If you want powerful voice in some notes, some of the 2nd~4th TMG area often has powerful quality, so you can make it wide.
4. death voice / vocal fry: delete the parameter of PIT by selecting eraser tool and dragging with Shift key on PIT in the note
https://cevio.jp/guide/cevio_cs7//songtrack/song05
It gets complete death voice (or breathy voice). Some use it as lapping it over the ordinary notes on DAW.
If you use it at the certain short part of the note (such as beginning), it sounds like vocal fry.
