Greetings! Trying to get a Korg EPS-1 Electric Piano and Strings keyboard back in shape. While keys are unavailable for it on Syntaur, I’m wondering if keys from similar models of that era would suffice? Specifically looking at the Sigma, Lambda, Trident with similar large poly keybeds and similar assemblies for the era. Has anyone had any success swapping parts? Looking for an E key and an A key.
