"Roland Super JX-10 Synthesizer with PG-800 progammer for sale. The JX-10 basically has 2 JX-8Ps under the hood with 24 DCOs in total, and was Roland’s flagship polysynth in the 80s. The electrolytic capacitors of the power supply in this unit have been replaced, as well as the battery. The synth is both functionally and visually in very good shape but the aftertouch does not work anymore – a common JX-10 issue. It comes with an M-64C memory cartridge. The Eprom has been upgraded to version 2.3 which drastically improves midi-compatibility."
