Yamaha CSY-1 Demo / Look inside

Published on Jan 8, 2015 opl3toshiba

"This is a demo of the Yamaha CSY-1 organ / synthesizer. The home organ case can be deceiving; this instrument has a built in fully programmable monophonic synthesizer. The built in synthesizer is identical to the Yamaha SY-1, Yamaha's first monophonic synthesizer made in 1974. When listening to this you'll hear the signature classic synth sound that defined Yamaha throughout their more famous CS-series. The VCO, VCF, and VCA modules in this synthesizer are derived from the circuits in the famous Yamaha GX-1 which was used by musicians including Keith Emerson and bands including Led Zeppelin."
