The heart of a Wersi sound system uses an OEM version of the Creamware DSP cards using the scope platform.
To give you an idea as to what this system is capable of, here is the link to the manufactures site, which includes demos of some of the sounds both they and 3rd parties produce with the system. http://www.sonic-core.net/en/home/index.html
Wersi of course produces its own sounds and effects; however it still uses the scope platform.
On top of this, the Wersi can also use VST instruments in combination with its own sounds.
