Finally Satisfied With Sonika's Vocal

I think I can just let go and move on. But I can't. After hearing some tweaked vocal track from one of the member in Vocaloid Otaku, Shoukka I decide to do more experiments.

I've change the key chord to low, middle and finally I decide it sounded good at A# or Bb.

Here's how it sounded.



But to my surprise, when I exported it as .wav file, the sound match to A instead of A#. I guess that's bugs?
