Contradicting itself there, it was either the same (discrete) VCO/VCF/VCAs of the OB-X
or OB-Xa 2 voice cards (using CEM/Curtis chips). Couldn't be both.
I wouldn't know, but I wouldn't use VSE as a definitive sourse either. Most of the write ups are out of date, and a fair amount of wrong information too.
