” Yamaha DX7S Digital Synthesizer Keyboard. Working and in good, clean condition. Includes 1 cartridge, volume pedal, music holder, and soft case.
Functionality:
All 64 of the cartridge voices function perfectly
The “internal” voices show unreadable special characters on the screen, and not all of them play a sound. Those that do are special effect type sounds vs instruments
I tested the headphone and 1/4″ outputs, as well as the volume pedal – all working fine. I do not have a way to test the MIDI ports” Click here to visit listing on eBay

“Additional Info: This synthesizer is being sold as is without a cartridge. The synthesizer has been sitting for a while so it could use some general clean up. One of the faders is missing its knob (see pics) but still moves up and down. The synth may have low battery as when we plug it in it does power up and kind of sounds. When we try to play it it seems like it wants to play and makes a static type noise with a very faint sound so it will likely need the battery tested and potentially replaced. The bottom plate is missing multiple screws (not included) and it is loose. “ Click here to visit listing on eBay

“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 search for synths on eBay
