Sorry to come so late to this thread, but it's the most relevant one I could find and I have a specific question.

If I create a song with my own chord progression, key and tempo, but it is entirely composed of realtracks, which I have generated repeatedly to find the one that fits best, and then used individually by exporting the .wav files and remixing them in my DAW...

Then is it a violation of the licensing agreement if I put that song onto a commercial album, without adding any other instrument layers to it?

Thanks for any light you can shed on this concrete use case.
