As you might already know, I posted some of my own observation on the DGX series keyboard. I thought the piano sound is good and even better than the higher end models such as the PSR1000 and PSR550.

However, the DGX200 and DGX300 has serious drawbacks that would prevent me from using it LIVE - no way of storing the registration.

DGX500 has registration memory but you cannot change the split voice independently. Just one shortcoming but a very serious one.
