Q: Does the AGPL license affect the copyright of the music I create?

No. The AGPLv3 covers the software code, not the media output generated by the software.

Q: Do I need to credit the plugin in my liner notes or track credits?

No. It is not legally required by the license, but we always appreciate the shout-out!

Q: Can I use this plugin in a proprietary DAW (such as Ableton Live, FL Studio, Logic Pro, Reaper)?
