Fairlight-CMI

This is a question specifically for Peter Vogel, presumably, but I thought 
I'd ask it here rather than directly as it has general relevance.

Now the Fairlight is about to become available again as a new instrument, 
does this affect copyright on Fairlight samples in any way?

For example, I used the Fairlight dog sample in one of my compositions a 
while ago, and made it generally known that I'd done it in case there were 
any problems with it.  That track is available on my website for free.

If I or anyone else were to use a sample from the Fairlight library now, 
whether in a freely available piece of music or in a piece for sale, would 
that now be an infringement of copyright now that Fairlight is trading 
again?  And is there any problem, retrospectively, with pieces like mine 
with the dog sample?  Or can we use Fairlight library samples without 
infringing anyone's rights?
