In mid-2009, I discovered Vocaloid, and then UTAU, and started to create my own voicebanks using my voice.
Unfortunately, during a severe depressive episode around 2015~2016, I deleted every video I had uploaded to my Youtube channel at the time. Unless some enterprising soul archived those pages to the Wayback Machine, those videos are lost to time.
THAT SAID, below are archived links of the last-update VBs I remember putting up for download, uploaded through Mediafire. They are free and intended for use in UTAU and OpenUTAU.
