Innovative Technologies Deliver Full-Range Fidelity and Enhanced Low-End Response

To achieve the deep, rich tones of an acoustic piano within its compact body, the B1SP Digital Piano relies on KORG’s servo-assisted MFB technology, a pair of full-range speakers, plus a passive radiator.

Together, these elements reproduce the rich resonant tones that emanate from the large body of an acoustic piano, with particular attention paid to the low-frequency range.

MFB (Motional Feedback) Technology: The built-in speaker system is equipped with MFB technology. This active servo system controls the movement of the cone, allowing low frequencies to be reproduced with minimal distortion. In use, the movement (velocity) of the speaker cone (vibrational surface) is detected, and a signal that compensates for the mechanical response of the speaker and speaker chamber is returned to the amp (feedback). This Motional Feedback technology allows the system to achieve ideal frequency response, and permits the low-frequency range to be reproduced accurately; any coloration of the sound caused by the speaker enclosure is immediately corrected. This well-regarded technique reinforces the low-end response—particularly with small speakers—and can also help to compensate for the room acoustics.

Eight Expressive and Highly-Detailed Instruments Sounds

As with all digital pianos, the KORG B1SP uses sampling technology (multiple digital recordings) to capture and recreate the rich, vibrant tone of an acoustic piano. As sampling technology has continued to improve—and as digital memory components have become more abundant—the KORG B1SP Digital Piano is able to deliver a more accurate, authentic, and expressive sound than instruments of just a few years ago.

In addition to capturing the enormous tonal range of a grand piano, the meticulously-sampled sounds created for the B1SP Digital Piano also reproduce the sympathetic string vibrations and damper resonances that give the piano its character.

Three flavors of acoustic piano are provided; the B1SP Digital Piano also provides two electric pianos, a harpsichord, and two organ sounds—each delivered with precise realism. This generous set of frequently-used sounds allows any player to expand their repertoire to cover many musical genres. The dedicated PIANO PLAY button instantly recalls the Concert Grand Piano sound.

NH Keyboard

The B1SP Digital Piano is equipped with KORG’s NH (Natural Weighted Hammer) keyboard action. This Natural Weighting provides a heavier touch in the lower registers, transitioning to a lighter touch in the upper regions—just as on a traditional piano. The dynamic response of the keyboard can be set to match the playing style of any performer.

Modern Design

The efficient design of the B1SP Digital Piano encourages you to enjoy playing and minimizes distractions. Sleek and streamlined, the compact body houses the built-in speaker system, yet weighs only 46.30 lbs. (21 kg.) allowing for east transport—if needed. The depth barely exceeds 13 inches (336 mm), making the B1SP Digital Piano extremely agile and versatile when it comes to placement. Available in either Black or White, the B1SP Digital Piano can complement any décor.

Improved Music Rest

The music rest of the B1SP Digital Piano features a page retention pocket that keeps music pages and folios from turning unexpectedly during performance—printed music up to 10 mm (approx.) in thickness can be accommodated. This thoughtful addition allows you to concentrate on your playing.

This piano comes with a stable stand and a metal three-pedal unit.

The three-pedal unit ensures good operating feel, and securely connects the side panels like a crossbeam to provide even stronger resistance against twisting. You can practice confidently with the assurance that the stand will not interrupt your performance.

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 the student and teacher (or parent and child) 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.
