Comparison: Vocaloid 5 Amy vs Vocaloid 6 AI Sarah vs Synth V SOLARIA

So, were you as surprised as I was when Vocaloid 6 dropped? I had no idea it was coming. I've downloaded the trial and plan to do more extensive testing, but right now, I did a quick comparison between Vocaloid 5 Amy, Vocaloid 6 AI Sarah, and Synthesizer V SOLARIA (which is an AI voicebank). This clip is from an old song I did originally with Amy, so it was already tuned in the Vocaloid 5 editor. Otherwise, I didn't really do much for Vocaloid 6 Sarah or Synth V Solaria because I wanted the program to show what its AI can do. My belief is that I shouldn't have to do anything at all--a virtual singer AI should handle everything (eventually). I think the Vocaloid 6 AI is better than Vocaloid 5. But, Synthesizer V SOLARIA smokes both of them. I did the comparison in English because I'm not a native Japanese speaker, so I can't really distinguish if the Japanese sounds realistic or not. I did listen to Vocaloid 6 AI Haruka in English, and it actually sounds better to me than Sarah, who is the native English voicebank, so maybe I'll do further testing with Haruka. I really would like to check out AI Megpoid, though!
