From the NUAGE page on Steinberg’s site:
“Steinberg’s Nuendo 6 represents the basis for all functions and features that can be operated via the Nuage controller hardware. Large parts of the Nuendo code base have been rewritten in order to make Nuendo the “brain” of the Nuage controller. This also includes the creation of completely new program areas such as the revolutionary mixer concept.”
