Just to chime in here: the issue is distribution.  The address space of

the running Cubase application would constitute a "derived work".  It

involves copying (the binary image into memory) so a license is required

but as I understand it, that copying isn't restricted in the GPL like

distribution is.
However, if a user took an image of the running application's address

space and then distributed that image to a third-party, the user would

be in violation of the plugin author's copyright.  I would note as well

that with the proliferation of x86 virtual machines, this isn't actually

such a far fetched idea.
