Your rights
You keep the copyright in your recording. You are not signing it over.
What you give me is permission, and that permission is not exclusive — the recording stays entirely yours to release, sell or reuse anywhere else, including in your own work. You are credited on the release under whatever name you choose.
The licence
This is what the checkbox on the upload form refers to, in full:
The contributor retains copyright in the recording. The contributor grants Ömer Kurtuluş a worldwide, perpetual, royalty-free, non-exclusive licence to use, adapt, transform and recombine the recording within the corpus, and to publish the resulting works. The contributor may continue to use the recording for any purpose. The contributor is credited on the release.
Two things I would rather say than bury
The album is released under a Creative Commons licence. That means the finished pieces can be reused by other people — not your recording, but what the system makes out of it. If that is not something you want your sound inside, this is the moment to say no, and no hard feelings.
The album may be sold, on Bandcamp and elsewhere. The licence is royalty-free, so a contribution does not carry a share of income. Say no if that is the wrong deal for you.
The credit
The album comes out on Bandcamp in February 2027. Everyone who contributes a recording is named in the credits under their chosen credit name — there is no threshold, no "major contributors" tier, and one file counts. You will get the release link whether or not you buy anything.
Why the licence is perpetual
Because a release cannot be unpicked afterwards. Once a corpus is built, a track rendered and a record published, a recording cannot be pulled back out of it without withdrawing the whole thing. A licence that could be revoked would be a licence that could force the album offline years later, so it is perpetual and I would rather be plain about that than quiet.
Your details
The form asks for your legal name so the permission means something. Only your credit name is published. Your legal name and email are used for this project only, are never shared with anyone, and I delete them on request — write to contact@omerkurtulus.com and it is done.
This is a plain-language description of an arrangement between two people, not legal advice. If you want a lawyer to look at it before you send anything, that is entirely reasonable — ask me and I will wait.
