D-550

“Listing today a Roland D-550 rackmount synth. One of the older D-550’s Serial Number 832896 made in October 1987. Everything works well. it has been in storage (the back shelf for the last 5 years) As expected the screen was dim so I replaced it, loaded from SysEx Librarian the PN-50-00.syx Roland patches. It does have some rack rash and scratches from being racked and reracked for a few decades. This is an older vintage synth so returns are accepted.” Click here to visit listing on eBay

“Pulled from a studio that closed six months ago. Powers on but no further testing was able to be completed as we do not have any midi equipment on hand that will allow us to send signal. ” Click here to visit listing on eBay

“This is a Roland D-550 synthesizer module in excellent condition. It’s the rack mount version of a D-50, and is an absolutely ICONIC ’80s vintage synth. I recently checked all components, replaced the battery, and restored the synth to factory presets. It works perfectly.

I am also including the original manual (in excellent shape), power cable, and a model M-256D memory card with extra patches (these cards are rare, and can sell for $80-$100 on their own!)

There is a scratch on the LCD screen and another on the power button (see pictures), but they don’t interfere with the readability of the LCD or the function of the unit. The Memory Card has a slightly fussy pin shield mechanism (the little sliding protector that covers the data terminals), which is why I am throwing it in for free instead of selling separately. It works fine, but please consider the Memory Card as-is.

This is a legendary synth in excellent shape, and a great collection to any vintage collection :)”

“I bought this in 1994 and used it till around 2000 but have not used it at all since then.

It was always in a air conditioned pet free smoke free studio and I have only turned it on a few times since 2000 to 2012 and recently to record the MIDI parts into audio and it works great

It is in great shape as you can see in the pictures, the back light isn’t like new but better than some others you see on ebay recently, please zoom into the pictures to confirm condition, there are a few scratches here and there and it is a little bent on the bottom rack screw holes, it is difficult to tell but under bright light you see a bit of a reflection…it is not exactly museum condition but still better than recent ones I have seen sell on ebay, so it is priced to sell considering” Click here to visit listing on eBay

” This is a Roland D-550 Linear Synthesizer Synth Module Rack , considered vintage. Used in a smoke free studio, all features appear to be functioning normally including accepting midi commands. The main output may need some cleaning but other than that the unit is in good shape. There is just some normal scratches. Comes with power cord.” Click here to visit listing on eBay

“The internal memory of the first module is loaded with the Voice Crystal 2 card and the other with the Voice Crystal 3. Special note that the cards are not included, I loaded them into the internal memory when I had access to the them. You can factory reset them at any time for their original patches. Each had their batteries replaced at the time of this listing as well.

These also come with a custom-made rack house made to be carried and traveled with. There’s rubber feet on the bottom (circled in photo) and felt feet for carrying with the handle on the side (last photo). This was a well maintained unit, the only flaw is the top unit’s screen is no longer lit. If you are a DIY gearhead, this is a very easy fix. Both units come with their own power supply cable and the electrolytic capacitors seem to be in good shape as well upon visual inspection. I used both units with the D50 to have three different voice cards after purchasing these from an estate. They were previously owned by an member of the New York chapter of American Guild of Organists, who was the only owner. Again these are in great shape, I just don’t have the space to justify keeping them. ”

“Roland D 550 Linear Synthesizer in very good condition with card and manuals. A claasic synth used on a ton of albums from the 1980’s and early 1990’s. See http://bobbyblues.recup.ch/roland_d-50/d-50_examples.html#Jackson for a listing of some. Great sounds. Comes with original manual and a programmed sound card. This was used in my home studio which I had in the late 1908’s and early 1990’s. When I moved and took the studio down, I intended to set it up again and held on to everything. I now realize that that is not going to happen. This synth looks perfect to me. It has lived in the same rack all that time. When I powered it up, I got a message to change the battery (reasonable after 30+ years) so I replaced the internal battery. The manual looks new as well. This is still a great addition to any studio or any keyboardist’s rack.” Click here to visit listing on eBay

“Great unit. Pulled from a smoke-free, home studio. Cool sounds. I have two D550’s and a D50 and it is time to start parting with some of this stuff. The only issue with this one is that the backlight LED on the display went dark on me. However, it is easy enough to read and work with (see second pic.) Some scratches from being racked but nothing serious. Well loved. No cards or manual included.” Click here to visit listing on eBay

” Classic 90’s mega synth.. this D550 has so much sonic potential, amazing pads, strings, brass, basses, leads and more.. Nothing quite like a D50.. This rack works great.. No issues.. New battery installed yesterday.. good to go for years to come! ” Click here to visit listing on eBay

“Roland D-550 Linear Synthesizer for sale. Unit is in working condition, it passes MIDI messages, the internal battery has been replaced, the volume control and potentiometers have been cleaned with Deoxit F5. Due to the old battery being drained, the unit might need to have the factory patches restored by the next owner. There are some scuffs and scratches on the top panel, and a small dent on the left edge. The faceplate has numerous small nicks along the top edge, and there are some marks on the “tune” and “undo” buttons. The sides, rear, and bottom are in very good shape. Overall, the unit presents itself very well.” Click here to visit listing on eBay
