I don't know how to ask this but it has to do with synthv

[人ロボット歌]

so lately I've watched a lot of videos about kasane teto voicebank on synthv and so I'd like to ask how it's done and the voicebank setup (if you have any info)

teto got an official release on synth V it's like a legit actual paid voicebank from ahsoft lmao
