I'm level... 7, if only cause I'm aware that Vocoder was a thing (linked the video of it's demonstration in chat the other day) as well as Cantor (Vocaloid's early competitor). Probably would be more accurate to say I'm on level 6 though until I learn more about Kyoko Date, Euphonia, and MI Talk (Can't really see the words on level 7, so I hope I got the spelling right).
