“This Roland D-50 Synthesizer is in Amazing shape!” 
“Up for bidding today we have a Roland D-50 Synthesizer. This item is in very good shape, with only some minor wear on the sides and bottom. The display is not as bright as it once was, but aside from that everything is functioning as it should. It has been residing in my climate controlled studio for a past couple of years, however due to space constraints I have decided to part ways with this wonderful piece of 1980’s technology. I’m also including a Roland M-256E for storing additional patches. ” 
“Roland D-50 synthesizer. Fully working! Don’t let the fixer-upper condition fool you, it is functional and sounds amazing. I’ve been controlling it via midi and it works perfectly. Obviously will need some TLC; needs the upper 5 keys, is missing all screws for the bottom panel, contacts under buttons and keys need to be cleaned. Rust on inside bottom plate doesn’t affect the electronics.”

“ou are bidding on Roland D-50 linear synthesizer from 80′ era, the synth is in pretty good shape with some very small marks here and there-see pictures. It’s been tested and seems she works, but I noticed a few buttons like #6 and #8 and 2-3 more+ sometimes work, sometimes not or you have to push t harder even a few times. Synth has not been used several years and probably she need some contact cleaning, well, it’s your project. Meanwhile all keys work, display is good, all inputs and outputs work, joystick, sliders, vector joystick etc work fine. The synth goes with power cord, no any other accessories. Due an age and vintage nature item goes as is, no return, but as I said mostly works fine. Due those a few small issues the synth goes twice !!! cheaper, see pictures. Stand is not included, only the synth and power cord(not original) for sale”

“Roland d-50 synthesizer with memory card & power cord
“It powers on and will move through the functions. I hooked it up to a small amp couldn’t get any sound to come out. I don’t know if there’s an issue or it’s because there’s no memory card,or exactly why there’s no sound coming out. it might work fine it might have problems. on the right side there’s something inside loose. Might be a small piece of plastic or a screw I can hear it when I move the keyboard. comes with a Forge 2 hard case. The guy I bought this from said it worked and everything else that I bought from him has worked but I’m not 100% sure so I’m selling it for parts or repair. the price reflects that I think”

“Hi everyone. This a vintage Roland D-50 keyboard. I am the original owner and it has lived it’s entire life in a smoke free home. You’ll be hard pressed to find one in this condition. No problems, No non-functioning keys, or any other nonsense. Just simply a well kept instrument. I have all the original manuals, two rom cards, and all the information that came with it when it was purchased. It can be heard on many albums from the late 1980’s!! Back in the day, every big time artist had one of these on their keyboard racks. The pictures are taken in natural light. There’s barely even any dust between the buttons or keys! It was kept covered with a felt pad. The only thing to note is a small dent on the bottom (see green arrow). It will be well packed in bubble wrap to ensure a safe journey to you!! Thanks!! ”
