Hi, this topic has been bugging me a lot lately. Officially, if I'd arrange a piece and made the arrangement public (let's say, recording+sheet music, but non-commercial), and the owner of the copyright would be pissed off about it, or smell money or something, he/she(/the company) could sue. (if that isn't the case please tell me so)
Now, of course most composers are happy about arrangements of their music, (nobuo uematsu, austin wintory etc.) and post them on their social media, but isn't there a possibility that if the game developer company holds the rights (and/or the composer is very evil) that they could sue? (everything regarding this like personal experience is appreciated)
And another thing is, if I'd play a (paid) concert where I'd (partly) play my own arrangements, this would mean twice the trouble, (because it's a commercial use) wouldn't it? (and being from germany, I have to fill out forms for what I play. So I don't know what this would lead to, maybe questions like: "well, did motoi sakuraba give you the permission for this arrangement or not?")
(if this is in the wrong forum category, please move this thread, I just thought "help" was appropriate, and I'm kinda new, so...)
