1980s Yamaha CS-15 Vintage Analog Synthesizer Duophonic Japan, Fully Serviced

Up for sale, a Yamaha CS-15 vintage duophonic analog synthesizer in excellent condition and in perfect working order. A step up from the CS-10, the CS-15 is great for strange blips, bass lines, and tiny high-pass sounds, with a distinct sonic range all its own. Thoroughly cleaned and calibrated by our techs here at Mike & Mike's Guitar Bar and a very well-constructed instrument, the CS-15 is particularly user-friendly, with a knob, switch, or slider dedicated to every function. This synth boasts two multimode filters, and while it's a duophonic/bitimbral synth "on paper", a connection it to CV is required to get the extra voice. Each of the two VCOs has its own CV/Gate control.

The CS-15 offers exceptional flexibility of the VCFs and the routings to the filters and envelopes. You can rout VCO 1 to both VCFs and the VCFs to any of the envelopes positive or negative voltage. The VCFs are 12 dB/Oct and are switchable between low, band, or high-pass. They are the key to the sonic properties of the Yamaha CS family. Other features are noise, external-in for processing other sounds, LFO with Sample & Hold (for those bubbling sounds) and an individual auto-bend for the VCOs.

As the photos can attest, this synth is very clean cosmetically, with bright white level keys and all switches, sliders, and knobs intact. The enclosure shows only a few minor scuffs, and this thoroughly cleaned and serviced CS-15 is ready for stage and studio use.
