Yamaha sound versus the Roland sound...

For me its Yamaha allways trying to be superrealistic when creating sounds...
Where Roland in general tries to create sounds that sound great and are dynamic and expressive while played, but not necessarilly as naturall sounding as Yamaha..

To be honest, i had to listen a 2nd time and use my sennheiser headset, listening to them on my PC speakers only gave me a possitive expression of the soundquallity
