Have any of you heard of these? If not, here is some information. Vocaloid and Utau
They are voice synthesizing programs. This youtube user Sango312 is a very promising user of these programs. If your interested, I suggest getting utau (free) or vocaloid (paid) and looking up tutorials on youtube.
Personally I'm just beginning, and I'm making my first real attempt at a song with Utau at the moment.
