Copyright & Included Content
The demo projects and their custom content (vocal recordings, music data, samples etc.) are not 'included content' for your use. They are provided as instructional projects to demonstrate what FL Studio can do. You are not allowed to use any part of these demos or their content and to publish it (e.g. upload to YouTube, SoundCloud, CD Baby, Tunecore, Monotunes, MySpace - yes it still exists, private websites etc.) or to directly share derivative works without written permission from the author/s.
You are not allowed to use:
I really want to use something from above! - Open the demo project and look at the project information (press F11 or Options > Project info). Note the author/s and contact them for permission. If you are having issues contacting them, please ask on Loop Talk.
You are free to use all content that:
Additionally, FL Studio comes with a wide range of other cleared content (patches, video generator ZGameEditor Visualizer patches etc).
'Copyright' is one of the few legal terms that is almost self-explanatory. It is the right of an author to decide who can publish copies of their work (i.e copy right). But WAIT this also extends to derivatives of their work. Derivative works include remixes and new songs that include any part of the original work, no matter how short. Copyright is automatic, the author has this right the moment they create something new. Specifically what 'rights' does the author have? The right to use the legal system of any country signed up to the Berne Convention to stop their work being used and to have it removed from publication. Copyright does not require any formal registration, although it can be useful for establishing legal ownership in a dispute and provide compensatory or punitive penalties against the copyright offender, in some countries.
Regardless of what you see happening on the Internet, using another's work (music, samples, vocals) without permission is an infringement of their Copyright. Listing the original author/s does not change anything. You must obtain written permission to use anything that is not explicitly provided or sold as copyright cleared for use in music production. For your information, we also needed to obtain written permission from the authors to include their demo content for distribution along with FL Studio.
If you use something from another author, without permission or explicit clearance, then they have Copyright over your work. For example, say you use a kick sound from another track, and that kick sound was the original creation of the author, and you publish your track in any format, then you are in breach of their Copyright. It's simple, if you did not create content AND the content is not specifically provided as or sold as cleared for commercial use, then you should not use it.
The simple rules!
