If you composed original songs by using the four AI voice banks in the VOCALO CHANGER PLUGIN package, in principle you can sell them without entering into licensing agreements or obtaining permission, regardless of the purpose.

However, there may be some restrictions depending on other add-on voice banks.
Please refer to the EULA that is included with each voice bank.
Additionally, please contact the company responsible for third-party products and comply with Article 4 in the EULA.

In particular, please note the following items:
1) Disclosing or providing synthesized voices with lyrics that violate public order and morals.
2) Disclosing or providing synthesized voices with lyrics that violate not only the rights of the singers (voice actors) in this product, but also the honor, personalities, and other rights of third parties.

However, products other than 4 voice banks and third-party products have different terms and conditions. Please contact the respective companies for inquiries.

Please contact us for further assistance.
