Music compositions and lyrics are inserted on the editors screen according to the desired singing and music accompaniment. The singing sound is taken from the “sound library” which contains the sampling of sound recording from the real singer. Song lyrics are sung in English, Korean or Japanese.
This software was first released Yamaha on February 26, 2003. Techniques used are Connecting and Shaping Articulation Songs with Frequency Domain (Frequency-Domain Singing Articulation Splicing and Shaping).
