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

cs-40m “Selling my Yamaha CS40m duophonic analog synthesizer, the synth over all is in good condition with some wear on the wood panel sides. Functionally it’s in great condition, all pots and sliders move fluidly and was recapped and some other maintenance at the beginning of last year.” 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

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

“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

“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.

Ready to play.” Link

“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

” Yamaha CS-40M
duophonic synth with memory from classic Yamaha CS line

Two two oscillator voices (huge 4 oscilaltor unison), multimode filter, VCLFO (voltage controlled LFO), classic yamaha ring modulator, memories, huge amount of interfacing (both voices have their dedicated CV/Gate inputs) make the CS-40M a winner in plenty of aspects. Whether you are into the experimental territory or need a synth with refined sound with solid bass end, the 40M is a serious candidate.

Full service has been performed. All of the pots have been restored (very hard and time-consuming process bearing in mind the amount), the keyboard disassembled and serviced, all of the electronics overhauled and final calibration performed. Needless to say, the memory works just as it should. ” Auction ended. Click here to browse on eBay.
