[Independent beginner] Using Kasane Teto (official voicebank) with OpenUtau Mobile (unofficial fork) for commercial song release – legal & crediting?

I’m an independent beginner producer planning to release an original song commercially on YouTube Music, Apple Music, and other streaming platforms via RouteNote.

Details:

· The instrumental was made in FL Studio Mobile. · The vocals were synthesized using OpenUtau Mobile – the unofficial Android port by vocoder712 (GitHub: vocoder712/OpenUtauMobile), licensed under Apache 2.0. The repo states: “This is NOT the official OpenUtau application and must not impersonate the official OpenUtau.” · The voicebank used is Kasane Teto, downloaded from the official website (kasaneteto.jp).

I want to ask:

  1. Is it legally allowed to monetize a track made with this combination (unofficial fork + official voicebank)?
  2. Can I put (feat. Kasane Teto) in the song title?
  3. Should I also add her as a featuring artist in RouteNote’s metadata, or is it safer to only credit her in the title?
  4. Does the “not official” notice in OpenUtau Mobile affect my right to release commercially?

I’ve checked the voicebank’s terms and it seems to allow commercial use with proper credit, but I want to be extra sure before distributing. Any experience or clarification would be really appreciated. Thank you!
