Throwaway guy here yet again with some updates
Ok, so first of all, HUGE shoutouts to the person who gave me Oliver and V4Flower, you're goated fr.
Secondly, I found out about vocakey (the website with a bunch of baidu links), but I have no freaking clue how it works due to me being a big dum dum. Like, is it a torrent? Do I need an account or something? Am I going to get malware if I somehow click the wrong link on there? Pls help.
Last but definitely not least, I stumbled upon a tool that basically converts Retrieval-based Voice Conversion (RVC) models into these sorta pseudo-Diffsinger voicebanks you can use in OpenUtau. I tried it on models of Miku and Peter Griffin and it sounded surprisingly decent. The only downsides are that one, it still has that RVC jankiness, and two, it only supports Japanese and/or Chinese.
