With my last comment, I need to say that I am not a recording artist, nor do I have that much knowledge of sample library creation.
(I'm just living off of my parents' wifi in their basement so I comfortably complain at bigger corporations and encourage piracy to internet strangers.)
I don't know how NI handles their developers, so I'm going to imagine it's hard and frustrating to the point where retiring a well-known library is the better option (when you say "order new batch of serials", I didn't even know that's how it worked!). I don't believe ProjectSam is saying "we'll just get rid of it lol".
I think my previous input should be more directed towards NI themselves. If anyone can comment on this, maybe their handle on the sampling industry is forcing these sample developers to take these measures? I know there has to be something, with the rise of all these new samplers. If it makes vst's easier and cheaper to manufacture, I'm all for it.
You do you, ProjectSam. If it's troubling for you to keep True Strike around, then retire it. I'll be fine, I promise!
