“This is a MEGA monster analog synth that will only go up in value! LOW START and NO RESERVE!!
Its huge! loads of great fat warm analogue tone/ sound /clips on youtube (..reviews junkie xl etc..) of this lovely 70s synth in action –
It’s a real bargain for such a rare hard to find vintage synth and in very good condition – The sound is truly Unique very warm fat thick analog sounds..modern synths just do not come close to it –
They don’t make ’em like this anymore..It would just cost too much to make a keyboard like this now days.

I am Only selling as I just don’t have time to use it and need the space – It’s very big hefty and heavy approx 25kg
so pick up welcomed or buyer can arrange their own manwithavan/courier or I can send mainland UK for approx £60 –
I can pack it up very securely –
overall it’s in great cosmetic condition all sliders knobs working on this vintage & all powers up fine-
It is in working condition you can get some really awesome sounds out of this beast of a synth but, please note it is a vintage item – so would really benefit from a good once over service just to get it perfect as mentioned before
I Just haven’t been using it which is a real shame and
It needs to be used, loved and enjoyed – These synths just don’t come up on here eBay UK – It will only go up in Value!!
& Its the only one here !! a very rare item, a really beautiful 1970s electronic analog synthesiser keyboard!! ”

“Beautiful and incredible sounding Yamaha CS-40M vintage analog synthesizer from 1978!
This beast is much sought-after but rarely discovered in such a pristine condition!

It has been cared for in a smoke-free studio environment and never gigged (by me). Cosmetically it is a 9/10, everything looks fantastic.
There are a few dings on the wood work (see pics) but apart from that it is like new, amazing care taken of this keyboard over the decades.
I just had it serviced (see pics) and it plays and sounds like a dream!

This is your chance to get one of these rarities, and in much better condition than usual (see pics)
Functionally it is a 10/10, everything works and sounds great.
I hate to part with this one, it just sounds incredible, but I need to sell it so my loss is your gain, low starting bid and a short auction so don’t wait!” Link

You are buying this as-is

I get sound out of all keys a lot of the knobs work.

I do not know how to work a synthesizer ” Link

” Der Yamaha CS 40m hat 2 VCO und 2 Sub VCO pro Stimme und verfügt über 2 Stimmen! Er kann auch im Unison Modus gespielt werden was bedeutet das er dann 8 VCO gleichzeitig hat!

Ich habe den CS 40 sehr sorgfältig gerecappt mit High End Audio Kondensatoren von Nichicon im Netzteil sind Panasonic Low ESR Kondensatoren verbaut worden. Der CS 40m wurde von Yamaha als Konkurenzprodukt zum Minimoog gebaut! Und hat sogar die Möglichkeit Sounds auf 2 Bänken a 10 Speicherplätzen zu speichern. Man kann seine Sounds auch per Audiospur in seine DAW sichern und das Audiofile dann wieder zurück in den CS 40 spielen.” Link

yamaha-cs40m “This auction is for one vintage used 1979 Yamaha CS-40M analog synthesizer keyboard project. I purchased this keyboard several years ago and intended to restore it but I never got around to it. This keyboard powers up but does not produce sound. The “PORTAMENTO” slider is broken. With that being said, this keyboard is being sold “as-is” for parts or repair. Cosmetically, the keyboard shows wear including some spots where the veneer is worn and some spots where it is peeling on the sides (see pictures). All of the keys are in good shape (see pictures). This auction is for the CS-40M keyboard and power cord only. The keyboard stand in the pictures is not included. ” Link

cs40m” This is a very special and rare piece. Sam Masuko, Owner of Three Wave Music has done all of the maintenance on it. Over $500 in recent maintenance. I can not stress how mint this thing is, you will just have to see it your self.

It comes with a hard case (Calzone like), on which I replaced the high density foam this past month.

I will include a printed and bound manual. I will also include the Three Wave Music receipt which lists all of the current maintenance that was done.” Link

ds40m“Yamaha CS-40M Duophonic Analog Synthesizer

Super cool and rare analog synth.

I just had it serviced By Tim at PCS so it’s ready to play.

It has a couple keys that have to be pressed down a little harder but it only takes a second to get used to.

It has patch memory and it is able to store patches.

The load button isn’t working so you can’t input patches from a tape(the switch probably just needs cleaning).

The portamento slider is broken off but it’s still easy to move up and down.

It’s in good shape but it has some pitting on the front face plate.

It was made in 1979 but it’s in decent shape for its age.

These synths sound amazing and they are really fun to play.

This one is 120 volt American version so you don’t need to have a transformer to run it at 100 volts.” Link

CS-40M, Yamaha @ 19 December 2014, Comments Off on Yamaha CS40M

cs40m“It is mostly working but there is some issues with the pitch and scaling of the VCOs. The portamento is ‘on’ slightly and the control makes no difference (could be related to the pitch issues?) One of the memory LEDs is broken (althought the memory location still works fine) a couple of the pots are a bit crackly but i think a good engineer could get this synth back too perfect working order without too much trouble. (I will include a printout of the service manual too)There are some scratches and chips in the casing and wooden end cheeks, a small rust patch (just above the pitch wheel), some scratches on some of the black keys and one slider cap missing (there’s always one!) – I have tried to show all these defects in the pictures as best i can.PLEASE NOTE 110V ONLY” Link

CS-40M, Yamaha @ 22 November 2013, Comments Off on Yamaha CS40M

“You’re looking at a pristine Yamaha CS-40 analog synth that is fully functional and in nearly flawless condition. Only a few tiny scuffs on the edges betray the fact that this synth is nearly 35 years old! I’ve had it for 15 of those years, and originally purchased it from a seller in Japan. It’s been a dry, smoke-free environment since then. And when I say it’s in FANTASTIC shape, I mean that every single switch and knob on here is solid, tight, and clean. There’s no noise or crackling on any of the pots or I/O. The pitch bend and modulation wheel feel brand new. I even tested the synth-to-cassette desk patch backup function and it worked! (If you don’t know about this, Google the Yamaha CS-40M for more information on its unique functionalities!) This baby isn’t ready for a museum yet! Take it into your studio and start creating wild electronic sounds with a truly pioneering instrument! I’ve had a lot of fun with this over the years and hope that someone else will too. ” Link

“2vco’s , duophonic , with 20 patches of memory and excellent realtime control. Part of the yamaha CS heritage.
This one is in average cosmetic condition but everything is intact and fully working. The slider caps are not original.
Full service, including replacement of most electroytic capacitors (high quality nichicon) tantalum ,etc. Replacement of various op-amps and other IC’s. Working perfectly. ” Link

“You are viewing an auction for a Yamaha CS-40m Synthesizer. It is quite an amazing synth. Very warm classic vintage tones. Being that it’s duophonic, it’s a superb bass synth. There are some scratches on the wood mostly which you should be able to see in the pictures. Also a few of the knob caps are missing but all knobs do function correctly. Everything has been tested except for all the CV connections. These are very rare so don’t pass up an opportunity to own a hidden classic! It’s somewhat similar in tone to a Minimoog but can play 2 notes or also a really heavy unison plus many other added features! Shipping is expensive because this beast weighs around 60 lbs in the box.” Link

“Zum Verkauf steht ein sehr rarer Yamaha CS 40M duophonic analog Synthesizer.

Ein noch etwas unterschätzter analog Synthesizer aus den frühen 80er Jahren.

Der CS 40M hat einen wundervolles Multimode Filter und ein genial klingenden Ring-Modulator.

Es lassen sich ohne Probleme massive Bass und Lead Sounds aus dem CS40M zaubern.

Auch für abgedrehte Effektsounds ist die Maschine ideal.
Der CS40M ist ein richtig großes Schlachtschiff das einiges an Platz im Studio benötigt.

Das Gerät hat einige leichte Gebrauchsspuren.

Voll einsatzbereit, Stimmstabil und komplett getestet.

“Up for auction is an extremely rare, vintage Yamaha CS-40M duophonic analog synthesizer in very good condition. Its features include 2 VCOs (triangle, saw, and square/pwm), noise, LFO, a multi-mode filter (low, high, and band pass), ring modulation, patch memory (20 patches), envelope generators for the VCOs, VCF, and VCA, and tons of modulation routing. It’s an incredibly flexible synth and is great for bass or leads in unison mode (4 VCOs stacked up), or pads and atmospherics in duophonic mode. The sounds is somewhere between a CS80 and CS15 and it has lots of knobs for editing and sexy wood paneling. This one is missing a few slider caps, otherwise in very good functional and cosmetic condition. No noisy pots, switches, sliders, key contacts, etc.” Link

“It’s a sad day, but I’ve given up with this beast. A large and heavy fabulous synth, two note polyphonic. It had some capacitor blow outs a few years back, which took out some chips, loads of 4000 series chips and capacitors were professionally replaced and it worked perfectly, but something else has blown recently and it’s time to give up. It looks in fairly good condition, but the painted front panel has lots of very small dots and blemishes where the metal panel has corroded. It still produces sound and all keys work but the pitch has gone way too high pitched, and the last notes played sustain forever.” Link
