“As good as you will find anywhere in the world. A few minor abrasions/dinks, if you look for them; but considering the instrument is nearly 44 years old, it is in great condition. Complete with original legs & music stand.” Click here to visit listing on eBay
“Has a small chip on front right and rear left, but all keys and pressure is working and is in very good order for such an old vintage synth. Been cleaned up from storage and plugging in and noodled around and all functions and controls appear to be fine. Could likely do with a tune up or once over but hard for me to tell, yet all functionality appears in good order – happy to demonstrate on pick up. Only selling due to moving and will not have space to play or store.” Click here to visit listing on eBay

For sale is a rare Yamaha CS-50 vintage analog synthesizer. This CS50 is in incredible condition. Hardly any signs of wear. It comes from the original owner and spent a majority of its life tucked away, and the condition shows how little it has been played. It comes complete with original manual, original foot-pedal (and soft-case for the foot-pedal) plus case lid and original legs. It’s fully functional and sounds excellent, a class synth. Being in such great condition it makes an excellent investment and should go up in value over time.” Click here to visit listing on eBay

“This is a fully functioning clean synth! Comes with original manuals, ID Warranty card, and the original pedal with case and legs. The exterior case in in decent shape. It has some marks and dings. I had this synth serviced in Portland, Oregon by Control Voltage. It has been in my personal synth collection the last 10 years. It is missing one input volume knob on the back exterior panel. (see photo). You can still easily adjust the level. I babied this thing and it sounds amazing! I am offering 200$ shipping and insurance on this item. If you pick up the synth in person however, I will refund you 300 dollars off the sale price. I would much rather it picked up in person than shipped due to its age and value.” Click here to visit listing on eBay

Huge sounding 70’s synth!! Plays and sounds like a dream!

“This is my original purchase in 1976. I can make you a mp3 or video of it in operation. Comes with the original expression pedal.(Newer expression pedals will not work) This is the classic baby brother of the CS-80. Same sounds less voices. This is a 4 voice. Aftertouch, glissando/portamento switch adjustable time for notes or chords that can slide or gliss to other chords or notes. Very cool implementation. I have not been able to duplicate that in modern equipment.
This is heavy. With the cover on and the legs and accessories which all fit nicely in the cover to make this a brick house suitcase it weighs almost 80lbs.
Check out youtube for sound demos from other cs-50s. Great instrument. Works great. Sounds great. ” Click here to visit listing on eBay
“The CS-50 is known to be like the younger brother of the famous CS-60 and CS-80. The CS-50 is a more simple version of the CS-80. While having the same audio quality at a much lighter weight, the CS-50 is a 4 voiced polyphonic synthesizer with 49 note keyboard which also has after touch feature. The CS-50 has 13 presets of various instruments and a panel section which allows you to design your own sound. You can be sure to get the classic Yamaha sounds from this synth!!” Click here to visit listing on eBay
“I am selling this fine piece of equipment because of lack of space.
It´s been under storage for the last 20 years, just tried it yesterday, still works like a charm.
I don`t use analog synths anymore, so I have no real use for it at this time, it should go to someone that is interested in going old school retro, Herbie Hancock used to play with an older version of this. ” Click here to visit listing on eBay
“There is 2 of the 4 voices sounding. Sounds like the 3rd is faintly there. Could be trimmers or a chip.

“I had this synth for many years. It’s been sitting for the past 15 years. It was working fine then but now for some reason, none of the “E” keys are working. I have no idea why. The sounds are working. The levers are working. There are no missing knobs or broken keys. I have the top cover and the music holder. I do not have the legs. I’m really going to miss this synth. It’s one of my many children. I just have too many bills to pay and I can’t keep everything.” Click here to visit listing on eBay

Fully serviced and tuned
Kenton MIDI Kit installed
Legs are sturdy and pack away securely in the case.
The only defect is the catch on the door behind which the power cable lives (pictured) won’t click shut but could probably be easily fixed by someone who knows how.” Click here to visit listing on eBay
Please see pics for condition – this wonderful synth has clearly been used and dinged up a bit, but it is still capable of producing some beautiful and mind-warping sounds. I’ve owned this synth for 8 years or so – not sure about the previous owner. I inherited it in the condition it is currently in – working but in need of a tune-up by a qualified service technician. Most everything works, although I could never get the “external in” to work (supposedly you can input sounds to run through the filters, etc). That said, the oscillators could use a tune up for sure.. I mostly used this for abstract sound and compensated for the occasional out-of-tune note by tweaking the pitch knob. If you want to play “normal” music with this in its current state, it would need to be properly tuned…
The knobs and sliders are mostly in tact (some missing.. see pics), but are far from mint condition. However, they all work. There is one broken key that needs to be replaced (see pic, a low E).
There are some goofy stickers on one side of the synth (see pics). The main On/Off switch looks like it has been chipped, and the panel by the On/Off switch is peeling off a bit (again, see pics).
All oscillator and filter functions seem to be working fine, and the ring modulator is glorious. Ditto for the touch sensitivity – one of the wonderful features of this magical synthesizer.
Again, this synth is being sold “As is” – priced accordingly for its rarity.”

“for sale is Yamaha CS-50 Vintage Analog Synthesizer. All sliders and buttons work but one voice is missing. Overall this synth works great and it’s in great shape yet has the normal wear and tear of a 40-year-old synth, so it’s sold as is.
It comes with the original wooden cover and with 4 chrome legs.” Click here to visit listing on eBay
“This one has ALL of the original pieces. The original case top, the original legs, the original leg braces, the original music stand, and the original manual. There is a nut that connects the original braces to the body of the CS-50, and I don’t know if it’s original, but it is perfect if it is not. This is a collector piece… it has everything that came with the original. The manual isn’t in the best of shape, but it’s all there. Also, sloppy use of the original legs can lead to stripping… but both the original owner and I have avoided using the original legs, so they are NOT stripped, and 100% functional.
The interior is CLEAN. It looks almost new.
Unlike the CS-80, this synthesizer is a BREEZE to tune, and it keeps its tuning. The CS-80 is sensitive and variable due to its complexity and case design. The CS-50 is MUCH more simple and open inside, and has ventilation and an arrangement that means that it doesn’t go out of tune. I haven’t tuned this since I got it, and it is STILL in tune with itself, and in tune with external sources. It is NOT unreliable, it is ROCK SOLID.
This synthesizer has been one of my favorites… and for years, it was my ONLY polyphonic. I am only letting it go because there is a synth I simply must have.” Click here to visit listing on eBay

“Vintage Yamaha CS-50 4-voice polyphonic analog synthesizer, unique Yamaha sound, in very nice condition. This synth comes complete with legs and rare music rest. Very expressive synth, with wicked ring modulator. The potentiometer for the External In level has a slightly bent shaft (see photo 5), but works fine. Otherwise, this keyboard is in excellent condition.
The synth is configured for 117-volt North American use. It is very heavy, and will be packed well, or local pick-up would be great. See our 100% positive feedback, and buy with confidence!” Click here to visit listing on eBay

The YAMAHA CS-50 is 4 voices of the legendary YAMAHA CS-80 (http://www.vintagesynth.com/yamaha/cs80.php), said to be the ultimate vintage analog polysynth by many specialists.
This one comes with its 4 original metal legs and lid (lid has additional metal reinforcements as shown on 1st picture). The power supply has been fully recapped before the sale and the sound cards recalibrated. In addition to these, it is equipped with a tuning card* and a MIDI kit that has :
– all of the main features of the Kenton kit
– control of brilliance (cutoff) of HPF via CC or velocity or aftertouch (impossible with the Kenton kit. The Kenton kit only allows control of LPF !)
– control of LFO depth to VCO and VCF via CC or aftertouch.
Full MIDI kit instructions are included
Kenton kit + installation sell for £612, here you have an even more developped MIDI kit which should then could be valued at at least £650. Meaning the CS-50 alone has a value of £1450 ! A true bargain…
*The tuning card installed allows you to tune the instrument yourself instead of going to or calling a technician to do it (like a guitarist tunes his instrument before playing…).” Click here to visit listing on eBay
“Up for auction is a Yamaha CS-50 analog synthesizer with four-voice polyphony. Same synth family as its famous big brother, the CS-80.

This synthesizer Includes original instruction manual, power cord, detachable legs and detachable hard cover. Instruction manual explains analog programming.

“This listing is for a Yamaha CS-50 synthesizer in remarkable condition considering its age (very hard to believe she is circa 37/ 38 years old). It sounds amazing, looks fabulous cosmetically and the keyboard plays like new. Any blemishes are clearly shown in the pictures so please inspect them closely. I can supply more photos on request. It comes with original legs/ braces and an external ac – ac convertor so you can run it from a British mains power supply (you can have the power supply switched over for circa £100 but I don’t personally feel it is worth it).” Click here to visit listing on eBay
