Korg's first preset synthesizer, using the same parts probably as the others of the era with a bunch of preset arrangements and attack/sustain and traveller much like the later M500, but 16' 8' 4' 2' sliders and a touch bar like Sigma but with Repeat, Forte, Pitch, Vibrato, Portamento routed into it's control rather than just vibrato! Cool!
Never seen one.
I believe you'll draw mostly blank looks from Korg on these units. I have some parts that are the same so feel free to ask what the current stock is on a given thing. Some of the less common parts are getting quite hard to find though. Contact
