I hate to be negative here... I really want to love this keyboard. With it's 76 keys, light weight, and chord sequencer,there are some great features. Even though the demonstrators have been very good players, I'm just not digging the sound so far.
No one says you cant just stay with what works for you.....its a new line of arranger keyboards released by Roland ...some may like them others won't no big deal.....try it, listen, if it excites you, if it makes you smile if you hate it you always have the choice top either but it or don't, keep what you have or wait for the next greatest keyboard to arrive in the coming years if you wish to change....meanwhile there is PLENTY of gear out there to create any kind of music you want.
Have fun with what YOU choose..
