ZEN-Core InsideThe GM-800 is built around the expandable ZEN-Core Synthesis System, the sound source behind professional Roland products like the JUPITER-X and FANTOM keyboards, the ZENOLOGY software synthesizer, and many others. ZEN-Core is the most powerful synth engine in Roland’s long history, distilling decades of expertise into one sonically vast and deeply expressive creative instrument.
Why Choose The GM-800 Guitar Synthesizer?
Over 1200 Sounds at Your FingertipsThe ZEN-Core engine combines modern PCM synthesis and advanced modeling to bring you an infinite playground for sonic discovery. Play acoustic pianos, EPs, organs, and orchestral instruments. Tap into classic Roland synths like the JUPITER-8, JUNO-106, and many others. And combine them all together to build sounds never heard before.
Four Tones Plus RhythmThe GM-800 features four Tone parts plus a Rhythm part filled with acoustic and electronic percussion sounds. Call up a part with the dedicated panel buttons, then explore a deep array of synth parameters, pitch settings, alternate tunings, and string assignments to shape sounds to perfection.
Intuitive Scene WorkflowThe ZEN-Core workflow is based around Scenes, which are “super patches” containing every element in a sound: Tone selection, parameters tweaks, sensitivity and other play settings, effects, and more. And thanks to the muscular DSP, you can carry over the sound of the current Scene as you select a new one for seamless musical transitions. There are 150 user-configurable Scenes, and 100 come with pro sounds ready to play immediately.
Roland Cloud ExpansionThe GM-800 supports an ever-growing range of creative options through Roland Cloud. Stay inspired with ZEN-Core Sound Packs and Wave Expansions. And play the ZENOLOGY synthesizer and legendary Roland instruments in your DAW from your guitar or bass. You can start using Roland Cloud right away with a free Roland Account and access additional content via three paid membership levels. All plans start with a free 30-day Ultimate trial to experience everything Roland Cloud has to offer.
Massive Effects Power
vast tonal potential The GM-800 packs the full effects range of the modern ZEN-Core system. With an immense variety of effect types available in each Scene, you can shape, enhance, and mangle sounds to your heart’s delight.
Dedicated MFX for Each PartAlong with their sound-shaping parameters, every Tone and Rhythm part has a dedicated MFX processor. Each offers over 90 effect types, including distortions, filters, mod effects, delays, and more. Many selections include two effect types for additional sound-shaping control.
Scene and System EffectsWithin every Scene, you also get two additional FX for processing the combined sound, plus high-quality chorus/delay and reverb effects with independent send levels from each part. And with the Master Comp and EQ, you can shape the GM-800’s sound output for any recording or performance setup.
Unlimited Guitar Expression
advanced pitch detectionThe GM-800 lets you harness an endless variety of sonic textures using the expressive playing characteristics of your guitar and bass. Optimize the performance with continuous pitch control or chromatic operation. Layer Tones to create rich, combined voices. Or assign them to individual strings, such as a bass sound on the low strings and a piano or sax sound on the high strings. You can even assign Tones to specific fret ranges, a powerful new feature made possible with the GM-800’s advanced pitch detection.
Next-Generation Playability The GM-800 delivers accuracy, stability, and real-time playability standards that far exceed previous systems, realized through skilled BOSS engineering and a high-speed processor dedicated solely to tracking. Multiple velocity and feel parameters let you dial in the optimal response for every sound and style. For example, you can set a Scene with piano sounds to respond to every dynamic nuance—from soft to loud—while setting another Scene with vintage analog synth sounds to the fixed velocity response found in the original instruments.
Compact PerformerThe streamlined GM-800 flows smoothly from desktop operation to installation on an advanced pedalboard. The four footswitches default to Scene selection and two unique control settings, such as pedal hold, pitch bend, or Tone selection. But you can freely assign them to control a variety of functions via a powerful Assign matrix.
Two external control jacks are also available, each supporting up to two footswitches or an expression pedal. And with five-pin MIDI I/O, you can interface with MIDI equipment from vintage to modern. s
