Continuing a Legacy of Innovation

Combining pitch and string tracking advancements with a cutting-edge sound engine, the GM-800 takes guitar synthesis to new heights.

ZEN-Core Inside: Sonically Vast and Deeply Expressive
The GM-800 is built around the ZEN-Core Synthesis System, the powerful engine behind renowned Roland products like JUPITER-X and FANTOM keyboards. With over 1200 sounds, the ZEN-Core engine merges modern PCM synthesis and advanced modelling, providing an infinite playground for sonic exploration. Play acoustic instruments, classic Roland synths, and craft never-before-heard sounds by combining them all.

Four Tones Plus Rhythm: Shape Sounds to Perfection
Unleash your creativity with the GM-800's four Tone parts and a Rhythm part packed with acoustic and electronic percussion sounds. Dive into a rich array of synth parameters, pitch settings, alternate tunings, and string assignments to sculpt your sounds perfectly.

Intuitive Scene Workflow: Seamless Musical Transitions
The ZEN-Core workflow revolves around Scenes, powerful "super patches" that encompass every element of a sound. Easily switch between 150 user-configurable Scenes, and with the robust DSP, you can carry over the sound of the current Scene to the next, enabling seamless musical transitions. Additionally, enjoy 100 pro sounds ready to play right out of the box.
