Free Audiomatic Rack Extension?
The Audiomatic Rack Extension is included free in Reason version 7 but is available to owners of Reason 6.5 and Reason Essentials too, as a separate purchase. When buying and registering Reason 7, a license for Audiomatic is automatically issued to your user account. To download Audiomatic, login in to Your Account, and click the Sync All button.
