Also, is it me having visions or does Rin's hairpin look like an N ? 

Kagamine Rin and Len have powerful and energetic vocals, and have been allowed to sing many songs. For the NT version, we considered the best voice quality and singing style to best suit Rin and Len as the default, and designed it so that Automatic Control and Vocal Morphing (a function that mixes two DB voices, similar to cross synthesis in VOCALOID) would allow for good dynamics.
I think the twin singers will be able to match the inspiration of users by adding tempo changes and singing in tricky ways, so please enjoy it. A free trial version is also in preparation!

This is a soft, ballad-like song with beautiful piano and strings. Rin and Len's expressive, free-flowing vocals resonate deeply in the heart, and are a departure from previous demos .
The first demo was a cool EDM, the second was a powerful rock tune, and this latest demo is an emotional ballad. Through these three different demo songs, you were able to get a feel for the breadth of expression that "Kagamine Rin & Len NT" have, and their potential to be compatible with any genre.
I don't know why, maybe this is just my own opinion, but even though some people might criticize f2 demo song, but I feel like Rin and Len's vocals sound much better in f2 demo song compared to f1 femo song, in terms of perhaps clarity and crispness. Forgive me but I think that f1 demo song has some "old radio effect" mixed to it, not sure if it is due to the tuning or mixing by the producer behind it or not.tomorrow is the release date, and to celebrate, third demo song!
Ooof, definitely heard the dreaded NT buzziness too. It just confirms what I've previously said about NT not handling softer voices well.That NT noise jumped out a bit more here, but imo if it can be easily improved with some mixing then it’s a big step up, and I still feel like they have a very good and faithful sound to them…
Kagamine Rin/Len NT Sonicwire product page:(translated from the original japanese blog post)
"Kagamine Rin" and "Kagamine Len" are each provided with "Original+" and "Whisper+" voice libraries, and the new "Vocal Morphing" feature makes it possible to blend between voice libraries. The voice libraries and singing synthesis engine (M9 engine) have been further refined for this release in pursuit of "Rin and Len's" authenticity, allowing you to experience the higher resolution yet still reminiscent of Rin and Len.
For those who are still considering purchasing, a trial version is also available.
Comment from Producer Sasaki (wat):It's been about five years since the original " Hatsune Miku NT " was released, and the development project has picked up pace since then. "Hatsune Miku NT (Ver.2)", which is more powerful with a new engine and "Automatic Control", was released in March of this year, and "Kagamine Rin & Len NT" was released in October, so we've been moving forward at a good pace recently.
I believe this is made possible by the intertwining of many elements, such as the support and encouragement from everyone, the motivation of our team members who never stop pursuing our own unique style, and the countless respects that arise within User Generated Content culture. I feel as though we too are riding on this kind of invisible force, propelled along on autopilot.
The "NT" development team will continue to conduct research and development that focuses on the unique characteristics of our Singer products.
The search for the next "likeness" continues without a moment's rest. We will keep you updated with further updates!
First released at the end of 2007, Kagamine Rin & Len gained popularity thanks to their distinctive, energetic and powerful voices and the two's catchy characters, and we were able to take on a variety of songs, from original songs by creators, mainly on Nico Nico Douga, to humorous comedy songs and ballads.
Following subsequent releases such as Append and V4X, I believe that in this "Kagamine Rin & Len NT" you can more quickly create the singing voice you like with presets for smooth singing (pitch transitions) and "Vocal Morphing" that blends voices.
As with "Hatsune Miku NT," we will also be increasing the variety and style of voices that can be created for "Kagamine Rin & Len NT," and developing the project so that you can choose and create voices to your liking. First, try the free version!
Yeesh.. Len, you OK there buddy? You don't sound so good... In all seriousness, Len sounds MUCH worse to me than Rin, and will probably need more work to sound on par with Rin/Len V4X. I think I'll pass on buying these, and save for V4X for now.Okay, let’s take a look at some real-life (raw or minimally edited) usage of Rin and Len NT.

We can see that... Rin Len NT's performance is not that much different compared to Miku NT2... Still with heavy engine noise...
So I guess, better wait for V6 voicebank or purchase V4X voicebank, unless want to try something indie or unconventional...
Kagamine Rin & Len NT is out today
We look forward to their voices connecting with people they meet and a new future!
