The 'Tears in Rain' monologue at the end of 'Blade Runner' is one of the most celebrated quotes in cinema. To support this philosophical moment, composer Vangelis used the Yamaha CS-80 synthesizer. The CS-80 is legendary for its 'polyphonic aftertouch,' which allowed Vangelis to add vibrato and expression to individual notes just by how hard he pressed the keys, giving the electronic music a 'living' quality. The lush, brassy pads and the melancholic solo leads of the CS-80 created the rain-soaked, neon-lit atmosphere of futuristic Los Angeles. It provided a soul to the 'Replicants' who were searching for their own humanity. The instrument itself became a legend among electronic musicians, as it perfectly translated the film's questions about what it means to be alive into a series of shimmering, analog soundscapes that felt both high-tech and deeply ancient.
