Dione's Act 1 supports both Latin and Japanese. The bank has syllables for both ecclesiastical ("church") Latin, and classical ("real") Latin. It is encoded in Romaji with hiragana aliases, and includes a tuned oto.ini: Since most Latin music is choral, Dione is intended to be able to sing as a miniature choir. However, her current voicebank is weak in the bass range. This is planned to be fixed with future updates/appends.
