You would put Harry Houdini to shame for avoiding what's in front of him. I ask you one question and you STILL do not answer me. So for the third time here goes.

Where do you think all keyboard manufactures get their sounds from?

Forget what you think about everything else and just answer that question. When you do, then apply the answer to your logic and you will see how it does not fit in at all with your concept of what copyright law on this issue is. I've had this debate countless times in all my years and nobody can prove it in writing what is right or wrong regarding this subject. All anyone can do is point out the obviously which is that everyone, Yamaha, KORG, Roland and everyone else are all at it.

So.... if everyone is at it and this is something you cannot disagree with,.... well what does that say to you?
