* 80 character backlit LCD
* Much improved MIDI spec
* 64 internal user patch spaces
* Fully dynamic key velocity across the whole 0-127 range (the original only goes to 99)
* Proper buttons and not the membrane type
* Much clearer audio (the original DX7s are quite hissy in comparison).
* 3.5" floppy disk drive (720k) for large storage of sounds
* Dual mode - play two DX7 patches at once for a thicker, richer sound - with Stereo panning.
* And a whole lot more besides...."
