A vintage, single oscillator analog monosynth. Part of the CS line that included the much sought after CS-80, used by Vangelis on the Bladerunner soundtrack. Used by Siouxie and the Banshees on the “Kaleidoscope” album, as well as Depeche Mode. This synthesizer has a very unique tone that some might describe as smooth, or bubbly. Certainly capable as a bass, lead, or sound FX machine! All the keys and knobs are fully functional.
