Yamaha DX5

Released in 1985

The DX5 is identical sound-wise to the legendary DX1 synthesizer - it is essentially two 6-operator FM synth engines (basically two DX7s) in one, that are layered together for a much richer sound. The 76-note DX5 keyboard does have aftertouch, but it does not have the wooden keys and polyphonic aftertouch that the DX1 offers.
