A New Kind of Singers——Virtual singers(Ⅰ)(2)

Last but not least, imagining you're using their voice banks（音源库）to write songs for any of them，actually, you're creating a new soul. Normally speaking, true stars usually perform live on the stage and the only thing you can do is cheering for them. But you can take part in composing and perfecting their imagery（形象） for them.(In my opinion, maybe virtual singers are waiting for you to write some, you probably make friends with them or other composers!)
