“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
DX Yamaha Data Cartridge 3: A (Master Group) and B (Keyboard & Plucked Group
DX Yamaha Data Cartridge 4: A (Orchestral & Percussive Group) and B (Complex & Effects Group)” Link

The last key is loose. Might be an easy fix, no idea.

I can get sound out but i really don’t know how this works. The screen seems good but I don’t know how to load the sounds. So it is what it is. The midi out was connected to another unit and it worked well so this is likely operator error.” Link

The keyboard itself is perfect, all buttons and functions work fine and there are no missing slider knobs. The display looks and works fine, and the internal data battery has plenty of power left in it.
Most of the original factory patches are still programmed in for those classic 80’s sounds.”

The keyboard itself plays like new: no chipped, wobbly, sticky, etc. keys All keys play at the same tension and attack.. All wheels, switches, soft switches, in perfect working order. I have never had it out of my house or lab; no gigging. A few scratches, previous owner had marked it with an “F”; none of which are noticeable unless you are right on top of it. It comes to you in the original sexy dark brown finish. There are thousands of original and custom patches available on line, we would be happy to help you download and set them up. I must repeat, this Dx7 is in amazingly excellent condition, like a trip to the past. From my own personal collection. ” Link

The membrane buttons even surprised me with how snappy their response is. It has a backlight installed, as well as a 90’s Grey Matter E! expansion, loaded with all the classic DX7 patches from the sound carts, plus some wild ones I programmed myself. I’ll ship it with priority mail, the cheapest fastest option, but shipping will be a bit costly because of how heavy this bub is.” Link

It featured a whole new type of synthesis called FM (Frequency Modulation) for those times.
Comes w/Cartridge & Stand.
Cosmetically is fine shape, with some minor scratching on the exterior.
Tested onsite and is in great working order.
Keys are all solid.
