"Roland’s ultimate polyphonic flagship from 1981, never bested! I purchased the unit (s/n 171654) in 1995 with the Encore MIDI already installed. A key feature of the Encore is arpeggiator sync via MIDI. It was a mainstay of our private smoke-free studio, and it’s the only Jupiter-8 I know of that has not needed any servicing for the past 19 years. It spent last week at The Analog Lab anyway, where the following spruce-ups were performed: The front panel was dropped and all controls were cleaned. The white modulation switch was refurbished with new contact material (it goes bad after a number of years). The keyboard was removed, all contacts cleaned and reinstalled. A full calibration was performed and all functions checked. Finally, the factory patches were re-loaded."
