“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!”

“This CS15 is in really nice shape. A couple of minor scratches on the front panel that have been pretty well repaired and no other damage to speak of. Works nicely with very little crackle from any of the pots. I have swaped the transformer to 230v (was Japanese 100v initially), replaced a faulty IC in the power supply circuit and replaced a few capacitors that were on the way out. Finally I have re-tuned as per factory service manual. Im an electronic engineer by profession and restoring & enjoying analogue synths has been a hobby for more than a decade, so it job has been done to a professional standard. Please check my feedback.” Click here to search for synths on eBay

“YAMAHA CS15 Monophonic Analog Synthesizer. This is a great lesser known mono-synth which I’ve used extensively for both bass and lead sounds. It’s added secret weapon is the audio trigger input which is a super cool feature for adding dimension to other sources such as kick drums. Was serviced a little while back by top UK tech Tim Wallhead and is all in good working order apart from one missing slider cap on the pitch bender (see photos). Condition is “Used”.” Click here to search for synths on eBay

“Selling my incredible Korg CS-15 which I had completely serviced last year by Rosen Sound. It’s a 100v Japanese unit that has been rewired for 120v so you will not need a step down converter. Everything works perfectly as it should. It’s got custom black wood side cheeks as well as a 3.5mm Kenton filter socket. Also included is a really nice custom cover. This synth is an amazing machine and capable of some very unique sounds. ” Click here to search for synths on eBay

“Beautiful Yamaha CS-15 and case. The synth is in excellent (beautiful!) condition and sounds quite nice. I purchased it from Soundgas (UK) last year and they cleaned, tuned-up, and inspected it prior to shipping it to the states. Please note: this is a Japanese synth and requires a transformer (not included). Also, the case does have one broken hinge, but otherwise it is in working order. Comes with original manual.” Click here to search for synths on eBay

“Up for auction is this Yamaha CS-15 Monophonic Analog Synthesizer. This works but is being sold for parts or repair. Unit has been in storage for a while and some controls need to be cleaned, they don’t turn, so unable to test if they work. The controls that I could test work fine. Unit is clean inside and out. Cosmetically very good but it does have some wear the worst being a chip by the power button. The tops of two controls on the equalizers broke off but they work. And a few plastic knobs are missing but for the most part the unit is complete. Please check the pictures for condition. ” Click here to search for synths on eBay

” Works. I cleaned all pots and switches it needs a technician to fix the decay or release of the tone . Unit passes audio , vcos and oscillators are functional but needs to be tweaked by synth tech to be 100 percent . I will list sold as is for parts not working but you can call me and I’ll play it so you can hear it . audio no distortion in signal at all . The only problem I see with unit is when you play a note it works but it doesn’t decay .”
