“Yamaha DX7s Keyboard Digital Programmable FM Synthesizer with Original Cartridge

This keyboard has had the onboard battery replaced with a new separate board isolating the battery from the rest of the circuit board. I read up on it enough to know that the coin battery had a propensity to leak which is why I replaced it with a separate coin battery holder and while I had it taken apart I took the opportunity to clean all the crud out from under the keys and even replaced a few.

The pictures attached show close-ups of the front the keys which are all mostly level. I suppose you could adjust the felt underneath one or two of them if you want to get them to a more precise level.

All 50 of the sound banks work though buttons 14 and 15 require a little more pressure to switch. I cannot test programming because I have no MIDI setup as I am not a musician. One of the reasons I originally wanted to sell this locally was that whoever bought it could test it out before committing to the sale.

The pitch wheel moves the notes up and down as I might expect but the modulation wheel does not appear to do anything noticeable to the note when I move it with a key pressed down. I don’t know if it has to be programmed or if the effect is only on certain sounds or maybe I just don’t have the ear to detect it.” Click here to visit listing on eBay

“Here’s your chance to allow me to thin out my vintage keyboard collection, and my loft insulation, and for you to benefit from owning a classic bit of 80’s kit at the same time!

Up for grabs is this original 1987 Yamaha DX7S, in full working order, and with the original factory patches installed.

I have owned this synth since new, and in that time, it has never missed a beat.

Cosmetically, it is in very good condition, with only a couple of marks. All keys still play perfectly, velocity and aftertouch work as new, and the semi weighted feel is very even and reliable. The display is still bright and legible after all these years.

The only reason I’m selling it is that I have 10 other keyboards in the collection, and very little space to actually set them up to play – so in preparation for that inevitable point in time where we “downsize”, I have to make a tough call.” Click here to visit listing on eBay

“This is an original Yamaha DX7s FM Digital Synthesizer.

It is important to disclose that while I am not a musician, and have not tested 100% of the functions of this piece, all the presets and buttons associated, from 1 to 64, were completely functional. The modulation and pitch controls also work. The edit, perfomance, and other keys also work. This machine has had a fresh factory reset, and uses the original cartridge that the machine came with from the factory. However, the dreaded “battery change” notification appears after powering on.

The unit is in excellent clean condition. No holes, burn marks, or even major scratches can be seen on the body of this unit. The display has some light micro scratches, but otherwise it is an exceptionally clean unit. The pictures do a great job at illustrating this. Units this clean and damage free do not come up very often.

The case unfortunately used foam inlays, and all the foam was rotten and falling apart. I did my best to clean and remove the foam so it would not get the keyboard dirty. To fill in the space, the voids will be filled with strong paper filling and the keyboard will be wrapped in plastic wrap to keep the unit in good clean order.

So due to the condition, I want to make it perfectly clear that I cannot guarantee the 100% functional order of this piece. ” Click here to visit listing on eBay

“I am selling this DX7s, which hasn’t been used for a very long time (I’d guess at least 20 years). I have turned it on and plugged it into an amplifier – and it makes sounds, so appears to be working. It does need a new battery (message appears on the screen). It has been carefully stored and comes with a ROKSAK gig bag which is only about 10 years old, or so. It has the cartridge inserted into the slot.” Click here to visit listing on eBay

“I’m selling my trusty Yamaha D7s keyboard. It has served me well but it needs a new home! I am the original owner.

I recently had the battery replaced professionally. One of the photos shows a full 2.9V charge. The pitch bend and mod wheel both work and all the keys deliver velocity and after touch info. Included is the Yamaha Data Rom cartridge with both internal and external factory voices. So, this DX7s currently has 64 internal and 64 external voices on-board. A few of the buttons (voice 24, 26, and 28 for example) require just slightly more than gentle fingertip pressure to operate.

I’m including a crinkled nylon “Cover Your Ax” dust cover. This cover has a small, clear glue stain and the elastic is not as tight as it once was.

The shipping case is a custom, hand-made case made out of approximately 1/2″ plywood wrapped in dark blue oil cloth. The interior of the case is lined with foam to provide a secure resting place for the keyboard. There are a couple small tears in the blue oil cloth. I would recommend adding a lid prop to keep the lid from opening flat and stressing the two bottom hinges.

I will ship the keyboard in its case – all in a cardboard container mainly to protect the shipping case’s cover.” Click here to visit listing on eBay

“This synth is honestly amazing, Ive had a lot of fun with it but as of lately it has been collecting dust, its missing the factory patch sounds due to the internal battery dying from being unused for so long, Ive replaced the battery already and it turns right on and works 100% fine other than that.
Reinstalling the patches is pretty easy you can do it using midi from your computer or from buying a cartridge and loading on it that way!
No cracks or any major damage on this synth just a few minor scratches on the bottom of the synth.” Click here to visit listing on eBay

yamaha-dx7s “mega awesome yamaha dx7s
you will know this from a million records
this has had a hard life..
cracks on the casing on the end- seems solid enough though
there is 1 spring missing from the lowest key and the highest key sits a couple of mm higher than it should
as far as i can tell everything works great – all the keys,all the buttons
im not sure the aftertouch works… its quite a complex thing to get my head round so i maybe havent turned it on somewhere?
screen lights up green
breath controller works with it!
was a good idea but i really am shit on keyboard – a one finger monosynth is more my style
its a heavy beast – weighs sooo much more than the roland sh2000 im selling
the sounds on this are absolutely stunning
this has a memory cartridge as well
think this is the 2nd version of the dx7 with better buttons and much more memory than the original?” Click here to visit listing on eBay

dx7s “This is a Yamaha DX7s Digital Programmable Algorithm Synthesizer keyboard with one data rom cartridge. It was pulled working from an audio production bay a long while back and has been sitting in the facility’s air conditioned storage room since then.

The long and short of this keyboard is that it may work or it may not. It powers on and comes up with the display exactly as you see it in the pictures. I don’t know how to service or program it. It may just need someone who knows what they’re doing or it may not be working, so it’s being offered for Parts or Restore. Please bid on this as if it is NOT working just to be safe.

At the very least it’s chock-full of great parts! Heck, just the cartridge may be worth the starting price… (of course I have no way to test it either)… ” Click here to visit listing on eBay
