I just wanted to chime in and say that if you are thinking about whether to get the mz x500 or something else....THIS KEYBOARD ROCKS!!!!!
I AM 70 YRS OLD AND HAVE PLAYED ALL KEYBOARDS...INCLUDING HAMMOND B3...SO IT WAS IMPORTANT TO HAVE 1- cool sounds
2- cool keyboard touch and feel....do0 not listen to the idiots who say the keyboard sucks...I LIKE IT BETTER THAN MOST OTHER KEYBOARDS.
The keys are not loose...in fact, they are fast, smooth and have a nice touch....comkpared to the Roland or yamaha in the same price range , these keys are waaaay better to play on.
The organ sounds cool and then you can create and save sounds easily...I am GLAD I bought this from sam ash....
