The amusing thing (to me at least) is that while the DX7 gave users almost infinite options as to how they could create and shape sounds, if you know what to listen for you'll hear the E PIANO 1 and BASS 1 presets an about half of all mid 80s hits. Turns out when they gave musicians a tool with immense flexibility, many of them still chose to use two of the (admittedly great) preset sounds.

To be fair, a lot of that is because the DX7 (or rather, FM synthesis in general) is just absolutely arcane when it comes to programming.
