GPL patches *can* be used as they are not compiled into an application and can 
therefore be updated by the user, satisfying one aspect of the GPL. I handle 
this in PdParty by having the built in patches accessible by the user in the 
app’s Documents folder, so the user can modify them at will.

If you’re using a GPL patch as an abstraction, it’s *similar* to using a 
dynamic GPL library as far as I can tell. But I’m no lawyer...
