“This listing is for a vintage Yamaha DX7 Digital Programmable Algorithm Synthesizer. It comes with Voice ROM #3 – A) Master Group

 B) Keyboard & Plucked Group  

It has been in storage for several years and has been dropped a couple times so the case is damaged. Also the plastic overlay has a couple of holes on the Memory Select Buttons.

It turns on and plays sounds when the keys are pressed. The velocity sensitivity seems to work like it should & the polyphony appears to be right.”

” This Yamaha DX7 is the cornerstone of 80’s synths… a beautiful instrument…

Trust me, I’ve owned 5 of them! This one is my favorite because it has the Grey Matter Expansion inside, which, if you do not know about it, please visit this website: http://www.muzines.co.uk/articles/grey-matter-response-e/2082

But, it is awesome…and it is in excellent shape (other than the physical wear from being over 30 years old).

I PERSOANLLY opened it up and cleaned and adjusted each and every contact inside so that there are no keys that have issues upon being pressed. (often, over the years, the contacts get dirty or bent, which impairs the touch sensitivity.

Rest assured, every key works perfectly and the inside is in excellent condition.

If you are not put off by the scratches and scuffs, you will be getting one of the best DX7’s around.

The Grey Matter E! expansion (which I photographed for you) is what sets this instrument apart from others.

ALSO, just another annoying thing that you won’t have to worry about: I replaced the battery inside (a little CR 2032 battery which controls the memory…often they are dead in 30 year old instruments…but I replaced it and soldered it onto the board as it is supposed to be).” Click here to visit listing on eBay
