The product has issues with ⟨A⟩ when used in conjunction with [-].
As pointed out by producer Cillia, Rin and Len are now easier to mix.
The total variation offered by E.V.E.C. and XSY combined is notably less compared to other V4X packages.
Discounting E.V.E.C., both Rin and Len each have access to the equivalent of 6 additional voicebanks achievable via XSY. The total tone variation offered by the package comes to a theoretical 9 voicebanks each in total.
E.V.E.C colors offer a further of 2 variations per vocal to each Kagamine. Once used with XSY 8 additional tones are achievable. So E.V.E.C. offers a further 10 tone variations per Kagamine.
All of his voicebanks are recorded in a chest voice.

All of his voicebanks can XSY with each other.

Has access to E.V.E.C.
The Kagamine V4X package, in contrast to the Megurine Luka V4X package, has only two E.V.E.C. colors; Power and Soft. This is because the situation was reversed, instead of having expressions and coloring them with tones, they have tones which were then colored with expression.
The Pronunciation Extension Function enables a to switch to a stronger pronunciation when moving from consonant to vowel.
This Stronger Pronunciation is intended to work along with GWL when creating a screaming voice, by turning on Stronger Pronunciation and adding a sufficient amount of Growl.
This can also create a trilled R.
His overall tempo and range has increased, allowing POWER to cover slower genres of music.
As well as Rin's POWER range being increased, Len's POWER also has a slightly increased range compared to his V2.
As with many other power voicebanks, the general performance of his POWER vocals produce a notorious sharp and metallic tone.
POWER serves to create tone variation and expression for Len by combining it via XSY with SERIOUS and COLD.
The expression can be controlled with both of his voice colors, Soft and Power. When used for XSY, this will adjust the expression further, allowing for combinations such as a softer POWER/SERIOUS XSY.
The vocal tone is that of a forceful vocal to give strong sounding lyrics.
Compared to Rin's POWER it is intended to be a more solid vocal with a chunky sounding tone.
He suffers from low-to-high octave transitions where he sounds less masculine in the higher octaves.
This vocal has strong consonants.
This was designed to compliment Rin's POWER vocal.
POWER is strong but flexible with a thick timbre.
Vowels drop randomly if XSY'd too much with COLD.
Usage of E.V.E.C. can make him sound like his throat is tight. Outside of this it has little to no effect.
Vocals should be compressed carefully when mixing to avoid overemphasis on consonants and to avoid overpowering the music.
Can produce very emotional and expressive singing when paired with some parameter and VSQ editing as well as vibrato.
Over emphasizes [h]. This is especially noticeable on his ⟨HA⟩.
Has difficulty transitioning between extended ⟨A⟩ based vowels when extended with [-].
He can use Pronunciation Extension which is designed to take GWL and other options into account. This version is only designed to strengthen the voice.
Sounds closest to his original ACT1.
⟨RA⟩ samples are noticeably weaker than her other samples but can be fixed with E.V.E.C..
Gives her more power.
A soft and gentle voice.
Range: E2~C4
Tempo: 60~160
Tone: Soft
Genre: Soft Rock, Ballad, Pop, Folk
Slightly increased vocal range compared to the VOCALOID2 version.
Without being used to combine with POWER, or just using POWER with no E.V.E.C. functions at all in place, COLD acts as a normal voicebank and will function the same as any other.
As noted in a comparison made by VOCALOID TV, both Len COLD and SERIOUS do not offer many differences between them, both having a soft airy timbre in the performance.
In this version of the vocal, COLD's ideal purpose is adding a tone to POWER mostly so is better suited as a second vocal in XSY. It will add the effect of a gentle soft tone which can then have its expression greatly adjusted using E.V.E.C.
COLD is the mirror vocal to Rin's WARM.
It is also supposed to be a moody atmospheric vocal.
It uses soft pronunciation that is not too loose.
COLD has a more open tone than SERIOUS, but is softer than POWER.
Len's COLD Append serves as a bridge between his POWER and SERIOUS Appends.
According to Wat, during the development of the original Append, it is like a combination of Miku's DARK and SOFT appends.
COLD is more focused on the highs of his range resulting in fuller high sounds but less attractive lower sounds.
Range: F2~C4
Tempo: 55~155
Tone: Soft, Mellow
Genre: Post Rock, Psyche, Ambient, Electronica
Without being used to combine with POWER, or just using POWER with no E.V.E.C. functions at all in place, SERIOUS acts as a normal voicebank and will function the same as any other.
As noted in a comparison made by VOCALOID TV, both Len COLD and SERIOUS do not offer many differences between them, both having a soft airy timbre in the performance.
In this version of the vocal, SERIOUS's ideal purpose is adding a tone to POWER mostly so is better suited as a second vocal in XSY. It will add the effect of a lonely soft tone which can then have its expression greatly adjusted using E.V.E.C.
SERIOUS is meant to be a contrasting vocal to Rin's SWEET vocal.
SERIOUS has a natural breath-sound, and is considered the most emotional of Len's Append voicebanks.
Len's SERIOUS Append can handle softer and slower songs better than POWER or COLD.
SERIOUS, being a whisper voicebank, has the potential to suffer from raspiness.
His range has been slightly increased.
