“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 search for synths on eBay

“Yamaha DX7 with hard case, used. Plastic ends are damaged around rear corners, missing knob cap on volume control. Custom hard case. Case is roadworthy, heavy and durable. Everything works great!” 
” Well equipped as a Synthesizer and Master Controller, all keys, controllers, and button switches function well, external samples can be imported via MIDI sample dump standard. Be aware there is a small stain in the bottom right corner of the display.(see the last picture),every bit of programming and required reading of texts in the display are 100% unaffected(no line intrusions,no symbol drop outs).There are light smudges on the top panel,and a few scuffs and nick on the bottom edge in rear. It plays well and sounds great and besides ADSR’S there’s total control of filter cut-off and resonance in programming and in real time w/ slider control and a Quick Edit mode option can get you to a patch result fast.
