Nope. Not saying that at all! Maybe I am not being clear. I fully understand that I can distribute any song I create with BIAB or with IK samples. And most libraries are like that.
What I am talking about is the re-distribution of your creation (which contains both your patterns/strums AND digitized instrument samples) for the purpose of facilitating others to use it!
No one is going to slice up your song and reuse it. And if they did you would obviously have a copyright claim. BUT, when you create a UserTrack using samples from a licensed library and then distribute that to others so they can use it to create songs that is where you have crossed the line in my opinion!
Let's take a simple example. NI comes out with some brand new, never before digitized rare Mayan flute samples in a Kontakt addon. They are sold as a library to allow you to add Mayan flute to your songs. You can create songs all day long and sell them or give them away and never have to pay NI another dime!
But then your friends over at the BIAB forums say "Hey, I want Mayan flute in my songs too but I do not wanna buy Kontakt!" So you say "No problem. I'll just convert them to UserTracks and give them to you!"
That is where I see a problem.
