The instrument
The Sequential Circuits Pro-One is a monophonic analog synthesizer released in 1981. It played a significant role in the development of 1980s electronic music, particularly in genres like synth-pop, new wave, and especially in the early days of techno music. Whether creating striking basses or high-pitched sounds, it quickly became a reference instrument for many musicians, including techno's founding father Juan Atkins.
"The Pro One is my heart. I'll use that Pro-One until it falls apart, and then I'll probably still use it if it makes any sounds." (Juan Atkins, "Future Shock" in Music Technology, December 1988)
Although its production lasted only three years, the Sequential Circuits Pro-One left a lasting mark on its decade and beyond with its sonic footprint. Today, it holds a cult synthesizer status and continues to be used in numerous contemporary productions. Like many vintage instruments, other brands have also produced hardware and software imitations of this famous instrument.
