HATSUNE MIKU V4X [初音ミク V4 X ] is the update of HATSUNE MIKU V3 [初音ミク V3] (which in turn is the update of of VOCALOID2 Hatsune Miku [CV01] and VOCALOID 2 Hatsune Miku APPEND [CV01a] ), made for VOCALOID 4.
In the HATSUNE MIKU V4 Bundle edition (初音ミク V4X バンドル), comes along with HATSUNE MIKU V4 English
HATSUNE MIKU V4X [初音ミク V4X] includes 5 Japanese female voices:
MIKU_V4X_Original*
MIKU_V4X_Soft *
MIKU_V4X_Solid *
MIKU_V4X_Sweet
MIKU_V4X_Dark
Three of the voices (all 3 with " * ") include EVEC.
This package continues to use the same original VOCALOID2 recordings from Hatsune Miku/Hatsune Miku APPEND . However, those recordings were "enhanced" and "cleaned up" for HATSUNE MIKU V3 , and again for HATSUNE MIKU V4X .
It is also supposed to include new recordings.
HATSUNE MIKU V4 ENGLISH is a new English voice for VOCALOID4.
This time, Miku sounds more powerful, with better pronunciation and clarity than HATSUNE MIKU V3 .
As far as we know, no recordings from HATSUNE MIKU V3 ENGLISH were reused, although it sounds suspiciously similar to MIKU_V4X_Original.
HATSUNE MIKU V4 ENGLISH can use cross synthesizer [XSY] with HATSUNE MIKU V3 ENGLISH since the November 19, 2016 update.
