Slim, light & compact design

The NP-31 is a truly portable piano-style keyboard, perfect for use in a wide variety of situations.

Graded Soft Touch keyboard

With Yamaha’s Graded Soft Touch keyboard, the lower keys are heavier in touch and the higher keys are lighter, just as on an actual piano, whilst retaining the softer touch of a digital keyboard.

Advanced Wave Memory (AWM) stereo sampling

Advanced Wave Memory stereo sampling is a system which uses sound wave data that mirrors the tone and expression of the original instrument using advanced digital technologies. It creates a rich and expressivesound by using multiple waveforms.

Built-in stereo speaker system

This instrument uses highly efficient amplifiers that create a poweful, natural sound from a compact speaker system.

10 voices including Natural Grand Piano

An ultra-realistic piano sound together with a selection of other instrument voices, controlled through an expressive touch-sensitive keyboard.

Dual voice

combine two voices together ( e.g. piano and strings) for greater versatility

Auto Power Off mode

The NP-31 comes with a new eco-friendly function that turns off the power automatically if the keyboard has not been used for a set amount of time.
