Well, I have to agree with NSR. When a keyboard is manufactured with the sole purpose of being sold to musicians or the musically inclined public, how could they possibly expect to withhold permission to use the rhythm backgrounds, fills or intro/endings? It was all created to intice the buyers to spend their money on the lavish, sometimes overpriced product, instead of something like a tuba, so the implied consent is secured along with the sales receipt. Who in their right mind would buy an instrument knowing they could never use it for entertaining others, either through live playing or by recording?!! Maybe that's why the manufacturering reps haven't said a word yet. You'd think one of them would reply and settle the question, especially if they could steer business their way. There are probably volumes of law books with case records concerning implied consent. It's probably a legal quagmire.
