The P255's arrived and I think I made the right choice. Now I'm able to play the P255 and the Kawai Grand side by side, the action on the P255 really is very good.
Well, it's arrived.
So, observations- You need an extra midi cable/thing to plug ipad/iphone into the usb port,
There are 50 demo pieces, many of which I've attempted,completed,am attempting, but these can't be paused or slowed down from the start (can be slowed to a lower tempo by reducing tempo once playing.) You can play back left or right hand parts individually.
Volume - does seem quiet, even in a small room.
Rythym tracks (not that I use them as stick to classical) actually sound good.
Very solid, quite heavy construction - possibly another reason the action/touch feels realistic.
I don't understand why the piano sound on digital pianos aren't more realistic - you'd think things would move on, but I think the p255 still has the better sound vs Kawai ES500, ES7, or P105.
