Native Instruments today announced the immediate availability of Reaktor 4 and Reaktor Session, the latest additions to its music software lineup. “Offering a powerful collection of virtual sound generators and effects that will bring new creative energy into any music studio, Reaktor 4 ($499) and Reaktor Session (US$249) give musicians and producers an endless range of possibilities for creating brilliant, unmistakable sounds. The completely new Library, with over 30 synthesizers, samplers, drum machines, live tools and effects, delivers the most diverse, high-quality collection of instruments ever assembled. The Reaktor family is now compatible with Mac OS X and has been radically expanded, boasting countless new features and a fresh new look. While Reaktor Session can load any Reaktor instrument, Reaktor 4 also lets users construct their own sound machines.”
