Yamaha CS01

“The synth powers on and makes noise..

However the machine is not working properly 100% of the time. The machine is temperamental.

The sliders function…

Knobs function…

There is one dead key and it is pictured.
Cosmetically it is not the prettiest.

Initially it seemed as though the keyboard was not working properly.” Click here to visit listing on eBay

Yamaha CS-01

“Yamaha CS-01 vintage analog synthesizer with case, strap, and Yamaha power supply. Item is in great shape and plays well. This is a great monosynth capable of very deep basslines. The model was reportedly used for basslines by Steely and Clevie of Jamaican dancehall fame. The synth has some slight discoloration/fading above the keyboard and some discoloring, scratches and paint chipped off (see final 2 photos) around the sides and back of the casing, but is otherwise in good shape for a vintage item. No battery leakage. Battery cover is included. Foam inside battery cover has darkened with age. Internal speaker works or synth can be connected to external amplifier. Carrying case is original and has some discoloration/staining probably rectified with a handwash. Strap ends are on the synth and the strap is included if you want to play it as a keytar.” Click here to visit listing on eBay

“First introduced in 1982, the Yamaha CS01 has been recognised by today’s electronic musicians as a very creditable synthesiser. It can run on batteries or 12volt power supply (not supplied with this offer). In excellent working condition with just a few minor blemishes on the casing.” Click here to visit listing on eBay

Yamaha CS01II

” You are bidding on a fully working Yamaha CS01-ii analog mono-synthesizer. The unit is in great condition, with only a few scratches on the bottom. I took the unit apart and inspected it and cleaned it where I could. All of the knobs and faders have been tested for proper operation. All of the keys work and I cleaned in the contacts on all of them. The unit works with both 6AA batteries or when plugged in (12V power supply IS included!). The circuitry looks to be in great shape (see pics).

This is a super cool synth from the 80s and sounds awesome. I’m amazed at the sounds I was able to get out of it being such a small compact unit from the 80s. This is is the second version of the the CS01, and apparently was the last analog synthesizer produced by Yamaha before they went digital. If you have been looking for a CS01ii, this is a great example.” Click here to visit listing on eBay

“Up for sale is classic Yamaha CS01 monophonic vintage analog synthesizer in a Limited Edition Black color, with rare original BC1 Breath Controller.

The unit appears to be working fine, all the keys and knobs and buttons working well including the built-in speaker. Maybe a slight scratch noise when controlling some of the sliders, which shouldn’t affect play and could probably do with some adjustment/servicing if required.

The BC1 Breath Controller is working fine too.

Cosmetically, the unit is in very nice condition as you can see. There are some wear and minor marks here and there but nothing serious. The battery compartment is clean, it worked fine with batteries as well as with my spare power supply. I’m including plenty of pictures so you can see exactly how it looks.

Both the CS01 and BC1 comes in Original Bags as shown.
I’m also including the Original Owner’s Manual written in Japanese.” Click here to visit listing on eBay

Yamaha CS01II

“Yamaha CS01 II analog synth in very good condition (there are some minor cosmetic scratches — see pictures) with a modification made so that the breath controller VCA knob has been replaced with a pitch bend range potentiometer.

In an unmodified CS01 II, I believe you only get a half or whole step pitch bend range. (It’s been a while since I’ve played an unmodified CS01 II, so I might be incorrect with the original range; suffice to say that it’s fixed and narrow.) With this modification, you get between a half step and an full octave pitch bend range, depending on how far you turn the potentiometer. This modification makes this instrument MUCH more useful.

After adjusting the pitch bend range, you may need to adjust the VCO pitch slider to bring the synth back into concert pitch, as changing the pitch bend range tends to make the overall keyboard pitch slightly different, but that’s a small inconvenience for having a truly useful pitch bend. I do not know if the breath controller will still work with this keyboard since it has been modified to have the pitch bend range potentiometer.

All in all, this little keyboard plays great, sounds great, and is a heck of a lot of fun, especially if you want retro analog synth lead/bass tones or want to make crazy experimental electronic noises.

Also included is a power supply and a photocopied service manual.”

Yamaha CS01

“Right this is a rare Yamaha CS01, a red one which I never see for sale. I think a later model which has blue highlights goes on occasionally but not this version? I pretty confident these things are pretty rare these days. Anyhow, I’ve had this since I was about 9 years old, I’m 43 now!! It’s been hanging around with me for years. I never use it these days, some switches are a little crackly when adjusting but it still works. All keys work great and all would be good until you wonder why it has a silver disc instead of the 2nd breath control knob. Well, I had a nasty habit as a young lad of taking all things electrical apart. I’d take them to bits to see what was in them and put them back together (Astro Wars lasted a month). Well, with this job young me did 99% of the job. I lost the knob and replaced it with another solid sturdy knob of some kind. God knows where from. This means that knob doesn’t work however unless you have the breath control it makes no difference (I never had it). It has lost its battery case and is scratched accordingly underneath. It’s also not been screwed back together perfectly so there’s some creaking going on. However, as I said it works perfectly (some crunching on certain knobs as mentioned). Now price wise I’m not too bothered if it sells and have lived with this chum for many years. I’m trying to raise some cash at the moment and so have plumed for a random start price. ”
