The bayan is a musical instrument, with full chromatic scale on the right of the keyboard and basses and chord accompaniment on the left. The bayan is one of the most perfect chromatic accordions in existence today. Known internationally as a “button accordion”, a multi-timbral version of the bayan is commonly used in concert performance as a solo, ensemble and orchestral instrument. The multi-timbral bayan is available with 4 voices, providing 15 different registers by selecting various combinations of the voices. We present a sample library of a four-voice Bayan for Kontakt.
