(i dont speak or understand a word of spannish so dont worry lol)
if you scroll down you will find letter in bold and alot of gibberish next to them.
the letters in bold are the sound, and the ones in the brackets are the input letters to make that sound ^^
im not sure if its the same, but this did help me, so maybe it can help you too =D
(you can always use a web translater to translate it all for you ^^)
I sing along to: Prisoner - Len Kagamine Butterfly on Your Right Shoulder - Len Kagamine Bonus Stage - Rin and Len Kagamine Kokoro Kiseki - Rin and Len Kagamine Remote Control - Rin and Len Kagamine Dancing Samurai - Gakupo Kaumi World is mine - Miku Hatsune Panda Hero - Rin and Len Kagaime (Cover version) Matyroshka - Miku Hatsune and Gumi Along with some others. I can sing these easily because I have a good memory. I don't know Japanese save a few phrases and words, although I do hope to learn. I hope you can find some songs you can sing along with in this list and if not find some on your own.
Nope it's just Rin and Len Kagamine
Both of their voice bank are by the same person and both speak in Japanese.
At the moment there is no announcements for a Len/Rin English voicebank, but in the future they may decide to make one.
It honestly is your opinion
December 27th
Actually, Len and Rin are "Mirror Images" of each other. Its because of their last name "Kagamine" from the word "Kagami" which means mirror.
Rin uses an electric guitar while Len uses a bass guitar
Assming you mean Rin Kagamine. Rin Kagamine is a vocal package for the software VOCALOID. So she doesn't really have emotions, but usually she's portrayed as being a couple with her twin Len Kagamine.
