Korg MEX-8000

“Korg MEX-8000 Memory Expander for DW 8000 EX 8000, DW 6000 Poly 800, Poly 800 mkII, DVP-1 – Maybe SDD-3300

With reprinted manual, 9v power supply * , 2 Midi cables

Fully operational and working with my DW 8000

New Back up Battery replaced with a coin cell holder

Old foam ( to secure AA batteries is you use them ) removed and replaced with new

All 4 banks are loaded with DW 8000 patches

This is a very rare memory expander (like a memory card) for several mid 80’s Korg synthesizers. It is compatible with the DW-8000, EX-8000, DW-6000, Poly 800 mk2, EX-8000, DVP-1 vocoder, and it may be as well for the SDD-3300, but I can not confirm that, and I do not know the DIP setting for that unit.

It has four banks of storage, each with 64 patches per bank. Takes about 5 seconds to Load or Save a bank.

One thing to note is that each of the banks can be used as storage for any combination of the noted Korg units, as you can set the DIP switch for each bank individually per bank.

For example you could have one bank dedicated to a DW-8000 and another bank dedicated to an EX-800 and so on. Or of course you can use all 4 banks , a total of 256 patches for one unit.

* Any 9v center negative 200mA power supply should work, or you can run this on batteries. The 9V supply I included works, but is not a tight fit in the jack. You need to rotate it to the position like in the photo for it to work.” Click here to visit listing on eBay

” This is a very rare memory expander (like a memory card) for several mid 80’s Korg synthesizers. It is to be used with the DW-8000, EX-8000, DW-6000, Poly 800 mk2, EX-800, SDVP-1, and SDD-330. It has four banks of storage, each with 64 patches per bank. One awesome feature is that each of the banks can be used as storage for any of the aforementioned units. You can have one bank dedicated to a DW-8000 and another bank dedicated to an EX-800 and so on. Or of course you can use all 256 patches for one synth.

The unit has some cosmetic wear and is missing one of the button tops (which does not affect it’s usage). The unit is completely functional and has been recently used with my Korg DW-8000 (see pictures).”

“Powers up but not tested as I no longer have anything to use it with

The MEX-8000 provides an additional 4 banks of storage for the following Korg synths and maybe more models from that era:

DW-8000 / EX-8000

Poly-800 II

EX-800

Poly-800 mk1 with MDK (MIDI Dump Kit)

It’s been sat around a while but not used and is untested other than power-up. Does not come with power supply but I tested it with a compatible unit and it powered up no problem. I used to use it with my DW8000 and Poly 800 2 but have moved those on a long time ago.” Click here to visit listing on eBay

“Comes with Power supply. Has some minor scuffing and minor scratching, nothing too unsightly though. Battery compartment looks very clean as well. Unable to test functionality but it turns on just fine. Sold as-is but seems as though it should do what it’s supposed to do.” Click here to search for synths on eBay
