“Yamaha DX7 keyboard/synthesizer. Has some scratches, scuffs, and labels taped on. Other than that it is a beautifully working and fully functioning machine. Comes with 2 cartridges and power cord. This synthesizer is heavy and the shipping cost will reflect that.” Link

“A series 1 Yamaha DX7 which I’ve had since about 1982. It’s in really good order for its age considering that it was in constant use until about three years ago when the band finally called it a day. The battery is currently reading an acceptable level of 2.8 volts but will possibly need changing over the next year or so.

Included in the sale are a Packhorse Flight Case, the two original data ROMs that came with the instrument and a BC1 breath controller (which has never, to my recollection, been used!

Most of the installed sounds are the original ones – we lost all the bespoke sounds last time we lost the backup battery.

The only modification is an IEC mains socket that has been professionally fitted in place of the rather awful fixed mains cable. I’ll throw in a kettle lead!”

“This keyboard is in good working condition. This is a legendary synth. It has seen better days, for there are some scuffs and scratches here and there. But it does not effect the sound in any way.” Link

“Used Yamaha DX7. Classic FM Synthesizer. Good condition for its age. I believe all functions/inputs/outputs work well as I have used it often over the past two years and never noticed any issues. Comes with additional RAM memory cartridge so that you can save more presets. ” Link

“This is a used DX7 with some cosmetic wear and there is a crack to one corner (see pictures). It also has a problem with one key occasionally and randomly playing itself (a low C#). Other than that it works well. Fine for playing and messing about programming sounds but you’d need to get it fixed for serious recording or live use.” Link

I also have many sound disks. If you need them, just ask.

Absolutely wonderful to play.

Awesome MIDI controller!

I placed a program/edit menu decal above the display.” Link

“Yamaha DX7 with Gray Matter E! Upgrade. I have owned the synthesizer since 1994. I haven’t used it for several years. It appears to be in working condition except that the battery needs replacement. There should be plenty of information online on how to replace the battery. All the keys and buttons appear to be in working order. Keys appear to be in very good shape. Still seems to play fine even with a drained battery. Some cosmetic defects (dent to the right of DX7 logo as seen in picture). There may be operational defects besides the battery that I am not aware of.” Link

“A classic synth I bought ages ago but never had the patience to figure out how to craft new sounds on it.

Comes with cartridge

The cosmetic condition is not great with the paint and one button has a chip on it (pictured) but the button works fine

Synth works great just its paint job isn’t going to win it any beauty competitions”

DX-7, DX-7s, Yamaha @ 09 June 2017, Comments Off on Yamaha DX7s

“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.” Link

“Up for auction is an early production Yamaha DX7, Serial Number: 8155, Manufacture Date Code: CB83000, suggesting that this DX7was manufactured in 1983. You can see this information in the picture of the left rear panel.” Link

DX-7, Yamaha @ 02 June 2017, Comments Off on Yamaha DX7

“For some reason when you play the keyboard to trigger internal patches, the keyboard gets shifted down a couple octaves and only plays low notes. However, when you trigger the synth via midi it works perfectly fine. The keyboard also works perfectly when triggering midi on external hardware. Output has a little noise. Comes with USB midi device so you can load patches onto it from your computer. Also comes with case if desired, will cost more to ship. ” Link

“Yamaha DX7 FD ll in good condition. It is in overall very good cosmetic condition. The first D&E keys have small blemishes at the bottom of them. (See picture) There are no issues with the display. All keys, pitch and mod wheels, and outputs function as should. The number 7 and 30 program select buttons require a firm push to trigger. I am unable to test the floppy disk drive so I can not confirm if it functions or not. ” Link

“Selling my dad’s old DX7 as a result of it suddenly developing a major fault mid-concert this winter.

The keyboard sadly no longer makes any sound, whatsoever, regardless of output used or amplification source. We have no idea what is the cause of the problem, or the fix, and don’t have the necessity for the keyboard any more to bother to find out.

Up until then the DX7 has worked flawlessly. The keyboard is in overall good clean condition. It has had its fair share of use in the nineties, but has been looked after and kept stored well in its case (soft case included in sale). The keys are not sticky and depress and release evenly and fluidly. The keyboard powers up fine and the LCD display works, although as before would display “grand piano” or descriptions of the sound option selected, now displays random characters as though the memory has been wiped. The cartridge is all there and included.

I do apologise for my poor description- I’m much more a pianist than a keyboardist! If you have any questions please feel free to message me, and I will ask my dad and my aunty to help provide as much info as possible. Considering how much of a cracking keyboard the DX7 is, it’d be a shame not to go to an expert in the field who could restore it to its former glory. ” Link

Tried with headphones and sounds great, no hiss or squeal. The DX7 does not have internal speakers, so you either need an amp or headphones. All the keys are free and easy workers with no sticking or chips. Comes with a printed copy (not original) of the complete 32-page owner’s operating manual, and three extra cartridges:

Sound Sources SX RAM 64 1,2
