Get the D-50 , it's capable of a wider range of sounds from analogue to digital . The V-50 is a pathetic 4 operator FM synthesizer like the D-21 , DX-100 , DX-27 . It has a very thin sound , very weak and anemic . The D-50 will be able to create some sounds that are somewhat like there older analogue gear and it can also do digital sounds as well . So basically you get the best of both worlds with the D-50 , later on down the road you can get the PG-1000 programer for it so you can have real time controls for it .
