Now you are asking way to much from the PSR2000! There is no sampling ram and there is no way to add sampling ram. This keyboard is a $1200.00 keyoard not a $4000.00 keyboard. Although the interface works much like the 9000, it is still more similar to the 740 in sounds than the 9000. The piano for example is like the 740 piano and not like the 9000 pro. This is because of the amount of rom designated to create the piano. I still think it is by far the best new product in a long time, but high end keyboards still are high end keyboards!
