It's just a grown-up version of the Lionstracs concept, but without the included arranger software (just as well, with how poor the MS's arranger section was).

As I've always said, it's the INTEGRATION of the sounds and the arranger software AND the styles that makes modern TOTL arrangers the amazing tools they are today. This is simply one more 'DIY' project for people that don't realize the skill it takes to 'roll your own'...
