"Reaktor 5.5 hat es wirklich in sich: Mehr denn je vermag die Software eine lange Zeit zu fesseln, denn Reaktor ist weit mehr als nur facettenreich. Vielmehr verdient das modulare Soundstudio den Titel 'König des Facettenreichs'."

"Native Instruments ist mit Reaktor 5.5 ein deutlicher Sprung nach vorne gelungen. Die Benutzeroberfläche ist wesentlich aufgeräumter als bisher.
