Stock, Aitken and Waterman used a lot of DX7 basses in their hits. In interviews in the 80s they would occasionally talk about their cartridge with DX7 bass patches and how no one would get access to it. Many decades later and the patches can now be found online. Just to make sure I asked Phil Harding if he was able to verify that these are indeed the real mythical patches and he, in turn, asked Ian Curnow. Ian Curnow is of course the guy that actually did the programming of most of it. He also made the Fairlight patches/sounds for "Never Gonna Give You Up" which uses one of these bass patches. Ian Curnow did confirm this is it.
