NotesNot everything was plain sailing, and it appears that Kakehashi infringed one of Bob Moog's filter patents when he designed the SH3. So a new version appeared in 1974. Externally, the SH3A was almost identical to the SH3, but it sported a new VCF and VCA, and it was this model that Vangelis and a handful of other famous keyboard players adopted in the mid-1970s.
