When you bought the refill, you should've received a User Agreement that clearly states what you can and can't do with the refill. However since it's a PH product, I wouldn't be surprised if it falls under the Reason End User License Agreement (https://www.propellerheads.se/agreements/#eula
(1.e.) "The musical examples
connected to the Software may NOT be used in any commercial music production
