To achieve the deep, rich tones of an acoustic piano within its compact body, the B1 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.
As with all digital pianos, the KORG B1 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 B1 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 B1 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 B1 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.
