Hi Guy`s ,
The actual keyboard sounds are ok , the Piano sounds ARE NOT pure roland , by any stretch the quality of say an FP-7f , of course that is "Super Natural" sampled.
Congratulations on your new keyboard. I find the same thing with Yamaha psr and Tyros- The piano sounds are not very good. I never understood why they don't sound as good as the Motif, S90, MO... Maybe the Tyros 4 has improved the piano sounds?
