Like the Mellotron was something quite new. the DX7 was another first. It was digital, but it used frequency modulation like normal synthesisers, but it FM's an oscillator which FM'd an oscillator, which... to create pseudo-random noise for those sounds which are noise-based. Quite a revolutionary technique.

Interestingly, the FM'ing of FM'ing of FM'ing arrangement for making random-seeming noise is nowadays employed in current fractional-N frequency synthesisers (the other sort of synthesiser!)
