A Yamaha hybrid piano is a real acoustic piano action with digital sound instead of strings, so there is nothing to tune and the touch is the touch of an acoustic instrument.
The AvantGrand N1X uses a genuine grand piano action, keys, hammers, and all, with no strings behind it. The NU1X and NU1XA use a genuine upright action in an upright cabinet.
This is the range for a player who will not compromise on feel but wants headphone practice, volume control, and no tuning schedule.
