“The keyboard powers on and plays sporadically, going from fully working to completely silent when pressing the keys like there is a loose wire or something. When playing sounds great and then will cut out and go silent. There is no middle sound like static or anything. The interior looks super clean and I didn’t not see a loose wire. It is being sold as is as described and will need some sort of repair. My gut says it’s pretty simple but I’m not an expert at all.” Click here to visit listing on eBay

“Classic Yamaha CS 01 mono synthesizer. Eighties vintage. Rare. With original padded case and power adapter. Gray with silver case. Tested and working. Clean. Ready for stage and studio.

I bought this when I was in a band during the Eighties principally for stage performances. It was barely used because the controls were difficult for me to properly operate in the darkness in the rear of the stage back there next to the drummer. As I recall, the songs it was to be used for got dropped from the set pretty quickly anyway. ” Click here to visit listing on eBay

” The Classic! Made only in Japan. Sounds so good. Tested and 100% fully functional.

Some cosmetic scratches, marks, and dings (see photos), but nothing that affects functionality.

Comes with case and manual. Manual not pictured as of posting but I will include it (it is in a storage space). “ Click here to visit listing on eBay

‘Up for auction is a Yamaha CS01 Analogue Synthesizer. If you know about these, you will know that this is not just any old mini keyboard, but a true analogue synthesizer in miniature, portable form. As such, these have been used by many famous musicians, including the Dust Brothers, Underworld, OMD, Richard Barbieri and Chick Corea.

It features a volume knob with power on/off switch, twin controls for the breath controller to apply it to either the VCF, or the VCA, or both in any combination (the input socket for the breath controller is situated on the left side of the synth). Note I am also listing a Yamaha BC1 Breath Controller, the correct one for this synth, in a separate auction. There are Pitch Bend and Modulation wheels, and the Modulation can affect either the VCO or the VCF. There is an LFO with Speed control. Next are the VCO controls, with a slider for Glissando (like Portamento, except that it moves in discrete semitone steps), Pitch slider, Feet multiswitch (with 32′, 16′, 8′ and 4’ settings, plus White Noise). Next is the Wave multiswitch, which selects between various waveforms, plus PWM. The PWM Speed slider is next (see note below about this), and that completes the VCO section.

Next is the VCF, with controls for FREQ CUT OFF, EG DEPTH, and a RESONANCE high or low switch. This is followed by an EG DEPTH slider for the VCA, and finally, towards the right end of the panel, are a set of traditional ADSR sliders for envelope control.

The above represent the standard controls of any conventional analogue monosynth, and anyone familiar with Moogs or similar will be immediately at home with this instrument.

This particular unit was bought for use in my personal studio, and has not been used on stage. It was always well looked after, and kept in the soft padded case it will arrive in. As a result, it is in excellent, barely used condition. I have checked it for faults, and everything is working properly, apart from the PWM Speed slider, which has no effect on the sound at all. Other than that, I would rate it at 100 percent. The starting price has been set with this in mind, and with no reserve this will be a bargain for someone.” Click here to visit listing on eBay

“Yamaha CS-01. Classic Vintage Analogue Monophonic Synthesiser.

Fully tested and working via the built in speaker with 6XAA batteries. Unable to test via AC as I do not have a suitable AC adaptor (easily available). I have not been able to test the Line out and headphone sockets either.

This is a classic early portable synth and is ideal for any musicians looking for that fat early analogy sound.” Click here to visit listing on eBay

“Yamaha CS01 early 80s mini-portable analog synth with original vintage soft case. The strap for the case is missing and no other items are included. This requires 6 AA batteries to operate and I used NiMH rechargeable batteries without any problems. A Yamaha power adapter can be bought for this but that defeats the purpose for a portable mini-synth. Some controls can be noisy when adjusted but that is common on 40 year old synths. Every control has been tested for proper operation and everything works as it should. The speaker, headphone output and line output all work. The only thing that could not be tested is the breath controller input as I do not have a breath controller.” Click here to visit listing on eBay
