Excerpt: I perform mostly on baby grand pianos but when I have a gig where there is not one the Roland RD300nx is really good. I like it a lot.The keys are some kind of new plastic that feels very much like ivory. The piano sounds are very good. You can adjust each piano sound with the lid up-down-or in between. The organ sounds are pretty good too. There are several samples of each instrument-not just one accordion, steel drum, marimba or vibes but several of each.
