The updated version of Hatsune Miku, in which the individual voicebanks are improved versions of the corresponding V3 voicebanks of the same names. It has slight improvements over the Kagamine Rin & Len V4x package and expands further adjustments made to E.V.E.C. It can be bought by itself or bundled with Hatsune Miku V4 English. However, the Hatsune Miku V4 Chinese voicebank is not included in any existing bundles with this release.
This package comes with Piapro Studio plug-in version. It was announced in August 2017 with the release of Hatsune Miku V4 Chinese that this vocal would have its own version of the Standalone Piapro Studio software. However, as of 1st Jan 2019 this version of Piapro Studio has failed to be released.
The software comes with a Piapro Studio version of Cryptons DAW "Studio One ARTIST", which includes various vocal effects and other tools. This includes also a resource pack with 200 virtual instruments. The complete package of Piapro Studio and Studio One ARTIST means that anyone buying this release can get started in music straight away with no need to purpose any further software, and all will work together with each other without any problems. This bundle is included in both the normal and English bundled versions of the software.
Amazon also offered the following bundles:
"Sakura Musical Instruments" starter set: Came with the Hatsune Miku V4 English vocal as well. Included in the package was a mic and stand, as well as the UAS-366-SC unit. Also included was the KORG MIDI Keyboard "microKEY-25 Air", Stereo headphones, a music stand plus two microphone cables and popguard.
This bundle was not intended for normal PC set up and were designed for a special set up. These offers were done as a promotion from DTM magazine.
Vocal traits as noted:
The vocals parameters are more effective overall and cleaner sounding.
It enjoys being mixed between 4K-9K equalization, meaning it can handle a variety of genres.
Due to the popularity of the Miku voice and the previous incarnations, the Hatsune Miku V4x can feel a little "standard" for VOCALOID because Miku has become "The Vocaloid" of the software.
Her release did not heavily get impacted by the update as Megurine Luka V4X was when VOCALOID5 was released as she can be used within VOCALOID5 without issues. Her V4x release did not rely as heavily on E.V.E.C. or additional Piapro Studio functions like Megurine Luka V4x did. Users should still be aware of the current situation with Piapro Studio in regards to VOCALOID5.
In total, the package offers the equivalent of 20 additional voicebanks achievable via XSY. The total tone variation offered by the package comes to a theoretical 25 voicebanks in total.
From Ver.4.3.0 of the Vocaloid engine, a XSY group "Miku V4x" was added to Vocaloid. All vocals within the "Miku V4x" group can XSY with each other. This vocal release is part of this group. If the User owns another vocal from the "Miku V4x" group, XSY between the vocals can occur.
The XSY group "Miku V4x" is the 3rd largest XSY group overall having a total of 12 voicebanks. If old versions that have since been re-released are removed, there are currently 7 unique voicebanks. These voicebanks are; "Original", "Soft", "Solid", "Dark", "Sweet", "Vivi" and "Light".
In total, the combined packages offer the equivalent of 132 additional voicebanks achievable via XSY. The total tone variation offered by the package comes to a theoretical 144 voicebanks in total.
This is not taking into mind the impact of E.V.E.C. on vocal XSY combinations within VOCALOID4 itself.
Note that "GWL" does not become viable for use with any V3 vocals used as the primarily vocal. This should be considered when using any vocal for XSY within the "Miku V4x" group from V3.
XSY is only possible with the full VOCALOID4 software.
Note that unlike many other voicebank updates such as Megpoid V4, the voicebanks have undergone slight changes compared to their past versions. Thus, XSY between "Hatsune Miku V3 Original" and "Hatsune Miku V4x Original" produces a slight change in comparison to "V3 Megpoid - Native" and "Megpoid V4 Native" which has very little change in comparison.
The only Voice colours are "Power" and "Soft". Like with the Kagamine Rin & Len V4X package it focuses on colouring tones with expression, instead of expression with tones like Megurine Luka V4X did.
The "Pronunciation Extension Function" has been expanded allowing for softer consonant impact in addition to the strong consonant impact. This allows for greater expression than the Kagamine Rin & Len V4x package offered. Miku's voice saw many new recordings for this function as a result.
