Roland Super JX-10 76-Key Polyphonic Synthesizer & Retroaktiv PG-800 programmer & Vecoven 3.23 & memory expansion & all tact switches replaced

This is the amazing (and ultimate version due to the upgrades installed) I’ve made Yamaha GX1 style strings and pads that are creamy rich, synth bells and FM Electric pianos, and killer brass and long pads, all are on my albums. Roland 16 voice Polyphonic Analog DCO Synthesizer that is in excellent condition Always kept in smoke free climate controlled home studio. Must sell to make space. I am the second owner, the first owner was just a collector and kept it in her apartment then sold it to me in 2021. In 2021 I had all the tact switches replaced because they all fail on these keyboards. I also installed the (look it up) Vecoven 3 Chip set (Rom A, B&C) which upgrades the entire operating system and increases the onboard patch storage to the equivalent of 32 cartridges ! and adds an Arpeggiator.. Also included synth comes loaded up with the two original Roland factory sound banks, and 9 more banks (cartridges) of sound patches from super-jx.com database and a patch list! Also included the Retroactive PG-800 MINI programmer for real time hands on patch tweaking and creation! I take great care of all my synths and this one is a beauty. Only the aftertouch strip was not replaced so there is no aftertouch however it will respond to after touch messages from another controller or computer/ DAW. Everything else works plays and sounds like new. 2 upper keys have slight scratch on them. Do the research and realize what you are about to buy, a powerhouse Poly Synth with upgraded parts, operating system, increased memory, and a Programmer. I also have all the original Roland rom chips that were replaced by Vecoven upgrades Should you wish to revert to factory chipset.
