Portable control USB copy protection unit (sometimes called ‘dongle’) that is necessary for using Steinberg’s software range. It stores licenses for Steinberg products and connected to a USB port on the computer – all of the products use a same system for copy protection. Several licenses can be stored on one unit and can be transferred between units with certain restrictions. This device is already included in all Cubase/Nuendo/WaveLab full versions, and is also required to run Steinberg VT instruments but is not included in the product boxes.
