YAMAHA CS-10 [VINTAGE] A compact and simple analog synthesizer originally released in 1977. This particular unit was manufactured in 1981. The CS-10 is a 37-key analog synthesizer. Although it has a straightforward 1 VCO, 1 VCF, and 1 VCA structure, it offers a wide range of sound-shaping possibilities thanks to its selectable high-pass, low-pass, and band-pass filters, as well as noise, LFO, envelope generator, and external input. It is simple and easy to understand, making it a great choice for beginners who want to get into analog synthesizers. The slanted control panel is easy to operate, and while the design is compact and charming, the sound is solid, rich, and unmistakably Yamaha.
