Synchrosoft/Steinberg auth system required now. Their site should be clearer about the whole thing. Only in the support area I've been able to find this:
* Soft-eLicenser: virtual dongle, a kind of cryptographic zone attached to your computer hard drive;
* USB-eLicenser: hardware dongle, under the form of a little USB key.

From a strictly functional perspective, you do not need the hardware dongle in order to operate your instrument on one dedicated computer. But you will need it if you are to use the instrument on several machines.
* The sedentary user, working strictly on one computer, can use the instrument with the Soft-eLicenser virtual dongle , by default installed on this music prduction computer;
* The nomad user, who works on several computers, shall use an USB-eLicenser hardware dongle to run the synthesizer on these machines. This dongle is also used by major editors in the music industry: Steinberg, Korg, etc. therefore definitely handy to hold several licenses on only one dongle. It is a pretty cheap device, that can be found about anywhere on the planet.
