Ooh, thanks Move! I looked through her site but I guess I must've missed that! I think I'm gonna do a massive saving up and get IA English's starter, ONE's starter (for the talk editor), and IA Talk. Might as well splurge and experience it allYes, she will have a Starter Pack! On her site is the text " [スターターセット (ボイス＋CeVIOソングエディタ) ] … ￥11,800＋税" which translates into "[Starter set (Voice + CeVIO Song Editor)] ... ￥11,800 + tax".
(She's also available without a Starter set.)
Apparently a Talk Editor also exists for CeVIO, so if you are planning to get ONE's talk voicebank, you will need to get this as well.
