“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!” Click here to visit listing on eBay

” 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.” Click here to visit listing on eBay

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. ” Click here to visit listing on eBay

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.” Click here to visit listing on eBay
