“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
