Up for bid is a vintage Yamaha CS-15, and manual (not original).
Great used condition, however it is missing two of the slider knobs (shown on the left side of the picture). This was used by my brothers band, but they no longer need it. I personally don't know much about it, but here is some info I have been able to find, as well as the web site I found it from.
Site #1: This unit has an external input, 2 outputs, 2 individual oscillators (no sine wave though), 2 filters (low pass - band pass - high pass, wonderful for ext. signal processing. Filters do self-oscillate if one of the two outputs is routed back to the ext. in!), 2 envelopes (can control VCF & VCA + EG #1 can be triggered with ext. signal), two VCA's, LFO with sine - ramp down -sample & hold (controls the VCF's & VCA's), portamento, glide, pitch bend slider, external/white noise signal can be mixed in with osc 1 (roll down the osc to zero with noise on 10 and trigger the cs-15 from a pad with EG 1 on ext trigger -cool hihats!) and lots of other features I can't remember. And oh, two separate VC and trigger inputs -almost a bitimbral synth ;) Triggering works great with Kenton boxes.
The Signal route is drawn on the front panel, so this synth is also good for learning how the analog synthesis works... The sound? With a one word -GREAT! Good for fat basses and thick leads, some weird sounds can be achieved with the S/H. The external input is a _major_ plus with all the triggering possibilities and for signal processing. http://www.sonicstate.com/synth/yamahacs15.cfm
Site #2: This synth really has its own sound. The CS-15's got style. Built like a tank with a lot of nice knobs and best of all, not one but two of those funny sounding multimode filters. It's actually a duophonic / bitimbral synth but you have to connect it to CV (Hz/V like Korg not V/Oct) to get the extra voice. Each of the two VCOs has its own CV/Gate control.
The best things about it are the 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 nice sound of the Yamaha CS family. Other nice 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. It has been used by Astral Projection, Somatic Responses, Moog Cookbook, The Human League, and Vince Clarke. http://www.vintagesynth.com/
