[kcwisao]

so, i like this one utau that i reeally like, i wanted to do a cover with them for a long time now. but i cant find any info on said UTAU (im nervous that it might a dscontinued UTAU that should not be used anymore idek)?????? there IS a wiki page for them (https://utau.fandom.com/wiki/MonoDia), though the links on it dont really give anything

I do have similar issue about keep using discontinued voice bank, if you can find terms of use that's great but, if terms of use doesn't exist, i think it's fine to keep using it even though it's discontinued. I do asked a lot of people about this on different forums and different commu, most people don't have any problem with it.
