I'd say when I tried PoPiPo on Sakanne in her early times x'D As I wasn't knowing how to pitchbend, I wanted for the "wiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii" to make i i i i i i i .... Well you know what I mean
And as she has a sharp voice and her oto was really off on that time I've made it, it was sounding a bit like Len's Migikata no Chou when it goes "wo-oh-ooooooooooho-o-o-o-o-o-o-o-o-o-o-o-o-o-o" except it was derpy and awfully robotic x'D Sorrowfully I haven't saved it so no audio file to show
And then my first attempt at Vocalshifter x UTAU... Oh boy, I wasn't knowing what I were doing and plus, I forgot to make something CAPITAL before pasting the pitchbends and dynamics... To put both samples ON TIME
And as result well... As Kei was also having is old voicebank sounding so weak at that epoca, and was sounding buzzy EVERYTIME EVEN ON TIPS and such, with this failed Vocalshifter use, he sounded totally like a drunk crazy android on Autotune x'D http://app.box.com/s/pyidq51r86hcoaoat7ex
It was so intense (and I died both of laughing and shame) that I even imagined to use this voiceclip one day in a video, when I'll make some MMD drama-like videos starring my UTAUs
Don't worry, with re-recording sessions and proper otoing + more knowledges about the program, he got better and is somewhat fine now. Thankfully for your ears XD
