"This Oberheim Matrix-6R is fully functional, in excellent condition and has been fully serviced. The Matrix 6 was one of the last few synthesizers from Oberheim to come out during the mid-eighties following the classic OB-series. The Matrix 6 utilized high-tech but less expensive digital and midi features and still retained a totally analog sound. It did this by using DCOs (digitally controlled oscillators) to provide stability, programmability and more. All the Matrix synthesizers featured Matrix Modulation which allows for extremely wild virtual patching for almost unlimited range of sounds and modulation capabilities! The Matrix 6R is a rack-mount version of the Matrix 6 retaining its membrane programming interface."

"Mint condition Kawai SX240. Replaced original eprom with Tauntek upgraded firmware (will include original eprom firmware if you'd like to swap back). Previous owner made a small modification to the left side of the synth. There is an xlr input and toggle switche installed into the metal chassis, but he never wired it up to anything (pictured). Includes original SX240 retail box."

No pics of the original box, but you can find some here. It appears to be the same one based on the XLR input mod. Different pics though.

"Probably one of the best kept instrument one could find. Hardly a scratch, not a spot of rust, inside or out. 100% functional, all six voices work perfectly. New backup battery installed. Nothing more to say. Perfect condition. From non-smoking studio."

According to the seller:

"This is a brand new, never turned on never used, just opened for photos Korg DSM1 Rack which is the rack version if the legendary Korg DSS Synth. It came from a Korg dealer that kept the unit for him but never opened it until I bought it. Comes as it came from Japan as it’s a Japanese made with all available sounds of that synth on floppies."
