In 1998, the Yamaha Corporation unleashed a product that was convoluted and bizarre like no other: The FS1R Synthesizer.
Like the era-defining DX7, the FS1R is an FM Synthesizer, but it boasts a massive 8 operators per voice, compared to 6 in the DX. And the FS1R sports a new toy, Formant Synthesis, capable of mimicking voices, human and otherwise! Waves and formants can modulate each other in 88 different configurations. Top that off with LFOs, filters, on-board effects… It’s so flexible, and so complicated. So much power.
