Warning, this thing is a mess timing wise.
This is timed specifically for koma'n's piano version of the song, and then I also did some timing adjustment in mixing as well. It's not really made for easy use, which is why I hesitated to share it here for quite a while.. Well anyhow! I did the tuning using Rin act2 originally, so the notes are minimally tuned since act2 rin tends to hold notes pretty well. Not sure how this will sound with any other vocaloid. This is my tuning from many years ago, but I think you can still find some helpful pointers with it since it's much more simplistic. (like using built in vibrato tool and PBS set to 2) Also there's one single spot where I used a 2nd track for a single note because I was testing stuff out at the time with that.
