Compact and affordable, the KORG B1 is perfect for both the home environment and for when portability is essential. The streamlined design delivers the key features most important to any pianist: an authentic keyboard touch, superior sound, effortless ease of use and a stunning design that complements any décor or setting.

Modern Design
Sleek and streamlined, the compact body of the B1 houses a built-in speaker system, yet weighs only 11.8kg. At just 336 mm deep, the B1 Digital Piano can be placed in locations which would be unsuitable for a traditional piano.

Eight Expressive and Highly-Detailed Instruments Sounds
The B1 features cutting edge sound sampling technology developed by KORG to recreate the rich, vibrant tone of an acoustic piano, including the sympathetic string vibrations and damper resonances that give a piano its character, delivering a more accurate, authentic, and expressive sound.

Graded Hammer Action Keyboard
The B1 Digital Piano is equipped with KORG’s NH (Natural Weighted Hammer) keyboard action. This provides a heavier touch in the lower registers, transitioning to a lighter touch in the upper area of the keyboard, as on a traditional piano. The dynamic response of the keyboard can be set to match the playing style of the player.

Metal Damper (Sustain) Pedal
The included metal pedal with the B1 Digital Piano provides a reassuring stability and a great feel underfoot. While the single damper pedal is convenient for many pianists, an optional three-pedal unit (PU-2) is also available.

Partner Mode
By activating the Partner Mode, the keyboard is effectively split into two side-by-side keyboards—each pitched in the same range. This allows student and teacher to play the same passages at the same time—the perfect way to learn a difficult lesson. In a classroom setting, two students can share a single instrument.

Outstanding Sound Quality
To recreate the deep, rich tones of an acoustic piano, the B1 uses KORG’s servo-assisted MFB technology, a pair of full-range speakers and a passive radiator system. Together, these elements reproduce the rich resonant tones that emanate from the large body of a traditional piano.
