i have a question re the mega voices on the MM6 and the Motif XS

Tyros 1 only had about 10 mega voices.
Tyros 2 has much more example - mega nylon, mega sax, mega brass etc

does the MM6 and the XS have the new mega voices that the Tyros 2 has??? becuase i dont think the MOTIF ES or the MO has these new mega voices...
