Independent shopping perspective
The Korena take
GM-800 brings ZEN-Core synthesis to guitar or bass through the Serial GK interface. It holds more than 1,200 preset tones and 150 Scenes, so a player can build and recall layered instrument and synth parts as a performance changes. Each Tone and Rhythm part has its own 93-type MFX processor, while the Scene offers two additional MFX systems with serial or parallel routing. Dedicated tracking processing and adjustable velocity and feel parameters let response be tailored separately for different sounds.
Strong match
Who this is for
- Building recallable Scene-based guitar or bass synth setups with layered tones and rhythm parts.
- Performance changes that call for different velocity behavior between piano-style and fixed-velocity synth sounds.
- Sound design using per-part effects plus serial or parallel Scene-level MFX routing.
