I asked the support of Garritan (GPO5) if it is possible to intervene on the vibrato of the violin.The answer was:That is a great question. For GPO5, the vibrato for the violin patches was recorded by the players and, as such, it is unfortunately not possible to change or remove the vibrato for these patches. Who knows if it could not be recorded even without vibrato, which not everyone likes. Thanks for your attention Renato
