The DX7 rebuilt for players who had learned what they wanted from the first one: the same six-operator FM engine, but bi-timbral, so two sounds can be split or layered, in stereo, with a bigger screen and finer control. Sold as the DX7II-D, the DX7II-FD with a floppy drive, and the cheaper single-timbral DX7s, with a 76-key Centennial edition in 1987. It sounds cleaner and quieter than the original, which is a selling point to some and the opposite to others.

The DX7: the sound of the eighties
Yamaha's DX7 put FM synthesis into a keyboard most bands could afford in 1983, and its presets ended up on a remarkable share of the decade's hits. How it came about, why nobody could program it, and eleven records to hear it on.

Why I still go into music shops
Trying the MODX M7 at Yamaha Music London, a chat with a stranger who owns a DX7II, and why the shop that gives you its time should get the sale.
