Free 'to your clients' isn't FREE. They have to buy something VERY expensive to get it.
BTW, just curious, but how much were you paying Norbert per installed Live-Styler? Anything? Or did you merely point your clients to sites where they could grab his program for free?
You have, in the past, said quite plainly and clearly that it is perfectly OK to copy some other manufacturers' sounds and use them (for profit, if able - after all, without a library of good 'stolen' sounds, how good did your original MS sound?). Apparently, back then, NO SOUND whatsoever had any kind of protection on it at all. You could clone a T2, a G70, anything you felt like. You also have said that the loops in an arranger were similar fair game. Plus the styles, etc., etc..
How is this any different..? You were profiting (by selling more MS's than you would have without these sounds) from this. How is Norbert any different..? Let's just say he's jacked up the price on his program, but he's giving YOUR sounds away for free... That's how you used to defend it!
Sauce for the goose...
