Currently out of all the released Vocaloids, iLove Iroha ! ;DD
Anyway, there you go ! There have been word that there may be more upcoming products if the fandom requests for certain types of requests (ex. Zero-G may update current released Vocaloids if fandom requests it, etc.).
NOTE: Kagamine Rin & Kagamine Len count individually as ONE VOCALOID; including ACT 1, ACT 2, and Append.
Hope this answered your question ;)
Akita Neru ain't a Vocaloid from the start.
I'm sorry, but no, once a VOCALOID serial number is used on one computer, it is no longer able to be used again. The VOCALOID serial number is a one and only thing. If it is used by another computer, then it will give out an error. If you purchase a VOCALOID you will not have this problem. So if you want a VOCALOID, you'll have to buy it.
Not yet.
on thiefy.com buy vocaloid and don't steal
You have to buy it to have an activation number.
Yes, Ai is a vocaloid. A vocaloid 3 to be exact.
Vocaloid fans like Vocaloid. Vocaloid fans are located around the world. Vocaloid fans also have a tendency to like Japanese animation (anime) and comics (manga).
Piko is the name of both the Vocaloid and the voice provider, who is naturally not a Vocaloid.
Miku Miku Dance software and Vocaloid products are not dependent on each other in any way. You do not need one to use the other.
MMD, or MikuMikuDance, is not the same thing as VOCALOID, as some people may think. It is a program in which the user can take VOCALOID characters and make movies using frame-by-frame motion. You do this by moving their bones and joints, then setting it each frame.Hope this helps~
No Teto is not a Vocaloid. I have heard before that She was made to be a prank. She is mistaken to be a Vocaloid. She sounds like a Vocaloid(y) software.
People are not sure if the second VOCALOID for the 1st generation was LEON or LOLA. They were both released on the same day. For VOCALOID 2nd generation, Hatsune Miku was the second VOCALOID after Sweet ANN. Lastly the VOCALOID 3rd generation, VOCALOID SeeU is the 2nd after MEW.
