i have been trying to download openutau for a while now and i succeded but there seem to be no voicebanks available, i want to use kasane teto but i can't find anything related to her for the love of me
Have you tried placing their voicebanks into the 'Singer' folder in the OpenUTAU folder? Similar as UTAU, there is a specific folder to place them there and with that you can automatically use any voicebank in there (well, small tamper and a few adjustments then it should work).
I think they thought that there is a menu to download singers from?
if thats the case, Kasane Teto, and any other voicebanks for utau, must be downloaded elsewhere
you can find her here https://kasaneteto.jp/utau/
then follow the instructions left by the others in this thread
