If I use your commercially available IR to get the guitar sounds I record onto my record and release for sale to the public, do I owe you a royalty?
Or was that use (for my personal guitar sounds) included in the license you sold me with the IR?
This is the same.
Okay then- so therefore I'm able to use your guitar sounds then for my own performance, which I release for sale to the public. I'm totally free to sample your music and use it for my own commercial purposes. Right?
I say it's not black and white - it's a grey zone that needs to be clarified by legal minds more finely tuned than ours .
