Yamaha DX7

“This is a Yamaha DX7 digital programmable FM synthesizer from the mid-1980s with memory cartridges in working condition.

This listing includes the read-only memory cartridges numbered 3 and 4, which contain the “master group”, “keyboard and plucked group”, “orchestral and percussive group”, and the “complex & effects group. These cartridges are tested with this synth and work.

This listing also includes a read-write memory cartridge for you to store your own DX7 patches. This is also tested and works.

The internal memory works too and includes the default set of sounds. However, the internal battery is low and needs to be replaced. If this internal battery dies, you will need to reprogram the internal memory, which can be done using free software like SysEx Librarian and the original soundbanks available from Bobby Blues website. Search the web for “Yamaha DX7 factory reset | Load preset sounds sysex” for instructions. If you can program this synth, you can easily learn how to reprogram the internal memory.

The volume slider is scratchy!

The wheels, buttons, and keys work fine. All the inputs and outputs work: headphones, main output, sustain pedal, MIDI, etc.

This was a working instrument for many years and it was used in smokey rooms in the 1980s and 1990s. This instrument is dirty! It has not been used in a smoking environment for about 15 years and it does not smell like smoke anymore.” Click here to visit listing on eBay

“Up for auction is this nice Yamaha DX7 FM synth. It appears to be in good condition aside from the big crack in one of the plastic side panels. I plugged it in and turned it on and it makes sound. I only played it briefly through a practice amp so I can’t really comment on the quality of the sound but it sounded nice to me. The buttons certainly change the sound and you can switch between the internal presets and the cartridge that is included. The cart is #4 Orchestral & Percussive Group / Complex & Effects Group. ” Click here to visit listing on eBay

Yamaha DX7 with E! Grey Matter Project Machine

“vintage yamaha dx7- the keyboard is clean with standard wear. when turned on the screen says ram corrupted. the internal sounds are zero. if turned on holding down #16 & #32 simultaneously the cartridges will play. I’m told the sounds have to be re-installed and the synth is a half step below C. There is a way to tune it but I don’t know a thing about the keyboard. I’m selling it exactly as photographed. No other parts, no cartridges. Consider the synth in ‘not working’ condition. It may be an easy fix for someone who has dealt with these before. I borrowed a couple of cartridges and the instruments sounded great through an amp. I bought it untested about 10 years ago thinking it was in working condition because it looks great, very clean. I thought maybe it needed a battery but youtube instructions looked too complex for a non-repair guy.” Click here to visit listing on eBay

“Yamaha DX7IID 61 Key Synthesizer- For Parts Or Repair. Cosmetically great condition. All keys, sliders, buttons, etc feel right. Unit powers up but nothing works- lcd display is illuminated, but no display and no sound. I bought this a while ago as is with hopes of replacing the mainboard someday but I never got around it. Prior owner told me thats what it needs, but I am not sure what is wrong with it really. Will ship it in a cheap keyboard case I have for extra protection. Again- sold as is- no returns- broken for parts or unknown repairs.” Click here to visit listing on eBay
