“Functionality: 10/10, Appearance: 9/10

This CS-15 has recently been gone through and given a thorough service. All electrolytic and tantalum capacitors have been replaced, along with the power transformer so that it can accept US wall power more easily ( it was from Japan, rated for 100v power). The tuning has been calibrated and tested and everything works and sounds fantastic! Cosmetically, it has a mark here and there, but overall looks great. Please see the photos for more detail. I would prefer local pickup on this, but I will professionally pack it using recycled materials if it comes to shipping.” Click here to visit listing on eBay

Selling this lovely dark horse of a synth from the 70s. This thing is very underrated, sounds huge and has a lovely bottom end. Two of everything – oscillators, filters and envelopes.

In fantastic condition, all pots and switches cleaned. Everything tested and working perfectly. It hasn’t been used much recently (hence sale) as I have got my cs-60 back from repair so that has taken over.

Collection only from East London. Or can look into posting but would much rather collection.” Click here to visit listing on eBay

“A classic Yamaha CS 15 analog synthesiser for sale. Circa 1980.

This was originally a Japanese unit, however a new internal transformer was fitted to convert it to a UK voltage.
At the same time the flying lead was removed and replaced with a much more convenient standard IEC plug.

This synth is in great condition as you can see from the photos and it sounds fantastic.
Just have a listen to some of the demos on youtube, the filters are amazing and smooth.

Also included is a like-new Kenton USB solo, which can provide MIDI over USB, to GATE+CV to control this synth.
I will also include the jack cables I made to connect the two.

The only issues I can think of is there are a few little marks at the top of the front pannel and a couple of the knobs are a tiny bit scratchy when turning them (a clean would sort them out), but given its age thats fairly remarkable.

Has been stored indoors as part of my synth collection in a smoke free studio”

“Item: Vintage Yamaha cs-15, 37 key monophonic (1 note at a time) analog synthesizer.

This item is in good condition, and I just played with it, and it plays fine and sounds fat.

Should work well for the buyer as it seems to be fully working. Nice sound. No returns, sold as-is.

This is the rare u.s. version with a 120v power supply. Missing a couple knob caps (as pictured)” Click here to visit listing on eBay

“Cleaned and calibrated, this vintage synth functions exactly as it should and has been outfitted with a modern power transformer to run reliably on USA 120v power. As the photos can attest, this synth is extremely clean cosmetically, with bright white level keys and all switches, sliders, and knobs intact. The enclosure shows only a couple minor scuffs, and this CS-15 is ready for stage and studio use.

The original black tolex carry case is equally as clean as the synth with a blush plush interior and flawless Yamaha silkscreen on the lid.” Click here to visit listing on eBay

“This synth really has its own sound. Lots 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.

These have been used by countless bands: Astral Projection, Somatic Responses, Moog Cookbook, The Human League, and Vince Clarke. Rare beasts now and much in demand for those musicians looking to escape the ‘in the box’ experience of DAWs or want real analogue rather than virtual.

This item isn’t a time warp piece and so has lost the fader cap on the pitch control and the EG1 release slider stalk has broken off but I haven’t changed it as you can still operate it fine. This unit looks to have been recapped and is signed inside S. Barbieri.” Click here to visit listing on eBay

“Yamaha CS-15 Vintage Analog Monophonic Synthesizer Working – GREAT!
Absolutely lovely and fat sounding synth! My favorite on my collection, that’s why it’s so hard for me to sell it but I have to let it go.
Physical condition is 7.5/10.
This synth has two of everything (oscillators, filters, envelopes, etc). The first filter is a bit noisy and crackly, but I’ve being using the second filter and that has worked for me. If you want an absolutely perfect working synth, you will have to take it to the synth doctor. Otherwise, great!” Click here to visit listing on eBay

“Yamaha CS 15 Rare Vintage Analogue Synthesizer
Massively fun and tweakable synth so many live switching and routing options it demands to be played…
This synth is a classic… a lesser known classic… the closest thing i can compare it to is the MS20
but it is a very different beast than the MS (it doesn’t squeal) in the right hands its a beast…
Duophonic it has CV and GATE (Hz/v s-trig) for each oscillator… then you get 2 of everything with interesting rerouting options…
external in… opens up more possible fun… I lost hours testing this thing… its hard not to get something intersting out of this thing!
Please note this is Hz/v s-trig CV control… I tested it with an Arturia beatstep pro (arturia is good for Hz/v)
Tested CV and GATE ins and both working fine and seperately together!!! 2 lines 2 filters 2 envelopes
I perfer to use just gate triggers and play the keyboard live because the live controls are a breeze!”
