The Fantom-X (Xa/X6/X7/X8/XR) is a music workstation/synthesizer produced by Roland Corporation. It was introduced in 2004 as an upgrade from the Fantom S series. The Fantom-X competes with the Korg Triton/Triton Extreme, the Yamaha Motif ES and other similar large-scope keyboards such as the discontinued Alesis Fusion. In 2008 it was succeeded by the Fantom-G, which was devised to compete with the new Korg and Yamaha flagship keyboards.
