User blog comment:Angel Emfrbl/Extra vocals XSY and all that.../@comment-32500188-20151201225646

10 voicebanks is clearly overkill IMO. GUMI is one of my top favorite VOCALOIDs to listen to (outside of IA), but honestly, I think Internet did WAY too much with her in those aspects. (Had this been last gen and earlier, it still would've been overwhelming but a lot more welcome than now.)

Don't get me wrong, I absolutely adore at least half of the new tone colors available, but honestly, I firmly believe that 3 VBs max is more than enough to create an even wider vocal range, since there's already the availability of brightness, gender (formant), and breathiness editing ... and had those parameters been even further advanced on top of XSY been created for the functionality of incorporating all 3 being used simultaneously in one parameter (on top of maybe re-introducing the Resonance parameter from V1 era), one would've been able to make some impressive results without having to rely on too many other VBs dedicated for alternate tone colors.

I know I've used the palette analogy in the past when it comes to different voice color availability... but after having had my share of joy in using XSY, sometimes it's good to just work from the primary colors to get the secondary/tertiary/etc. results from such.

(The only thing that kinda negates that feeling, though... Arsloid. And that's because it feels like his extra vocals either are missing crucial transitions or were recorded so differently from the base vocal that they don't really mesh as well as they should. So his existence with the many flaws his banks have definitely proves what you said when it comes to producing high-quality content. Goes to show just how much detail is required in order to make the results work, not just on the editor's development side but the library creation side as well.)
