Interesting question...can we take it a little further?
I too have been curious regarding the usage of Acid loops. I know the loops are royalty free, but how does that relate to copyrighting a song or CD, recording credits, etc? (This may be more of an ethical consideration than a legal one.)
A brief elaboration: I use Acid to create scratch tracks to take into the studio for bandmates and/or hired session players. I create complete songs with full instrumentation (my genre is blues, so for me this is primarily drums, bass, guitar...with vocals, harmonica and keyboards recorded by me). The intent being to give the basic feel and style of the song, but allowing the guitarist, drummer, etc., to lay down his/her own riffs.
In the event that I preferred some, or all, of the Acid loops on a particular song, what are the legal ramifications of copyrighting, publishing, and selling it as "my" song?
Even if I could do this legally, I would have considerable ethical problems with doing such a thing. Who would I credit with the appropriate instrumental parts? Although I may be the "composer/arranger", it was guitarist, or bassist, "X" who originally recorded the loops for Sony/Sonic Foundry. What if I created an entire "one man" CD? Who would or should get credit?
And what of the consumer? (This is for discussion's sake...I'm not flattering the commercial appeal of my music!) Don't they have a right to know that the CD they're buying was largely created from loops?
As the quality of recording gear and software increases, and the price drops, more and more people have the capability of recording their own music without having to resort to the expense of studios and other musicians.
Food for thought,
