The Steinberg Key is a copy protection unit (sometimes called "dongle") which is needed to use Steinberg's software range. With the host applications Cubase 4, Nuendo 4 and WaveLab 6, the Steinberg Key is already included in the product package. The Steinberg Key is also required to run Steinberg VST instruments, but is not included in the product boxes and must be purchased separately if no Steinberg Key is already present on the system.

The Steinberg Key comes with a CD ROM containing informative videos and detailed PDF documents about the entire Steinberg product range.

• One copy protection device for all Steinberg licenses
