In 1984, Kurzweil introduced a new industry standard of sampling excellence with a focus on future-proof expansion. The music world has undergone significant changes since 1984, but the K250 and 250RMX are still respected as leaders in the world of digital music technology. Forty years later the K250 has been reborn and is now capable of keeping pace with the present and future of music synthesis. We have developed a powerful new family of sound and memory upgrades providing direct connection to modern devices via USB. With these upgrades the K250 becomes more than a collectible and effectively give the K250 endless capacity for sounds created over the last 40 years and far into the future. Learn more about our new UltraMEM and UltraROM installation kits and other upgrades - which are continuously being updated. Today, your K250 can live up to its full potential and thrive.
