Actually, I saw that statement on the ZynAddSubFX site and assumed it was an extra clause in addition to the GPL. As Paul owns the copyright (which I assume he does) he's entitled to add any extra licence restrictions he likes to his own software, as a 'GPL plus'. That might mean it's not strictly 'software libre' of course, but Paul does say 'please' rather than 'you may not use' though. I'm unsure how the heavy metal clause is measured against, or enforced. We're not Satanists here, but the guitar riffs can get a bit heavy sometimes. Cheers Daniel
