TLDR: put it into moresampler because the auto oto generater isnt good on setparam
The auto generater oto sucks, at least in my experience. when i tried to make a voicebank once, someone told me to just take the voicebank file and drag and drop it into Moresampler.exe and answer the questions.
Jsyk when i used moresampler to oto my vb i found out it cant read any subfolders, so i had to rearrange my vb file to be like this:
Parent folder > Sound files
Sorry if i said anything wrong, this is just from my experience
