The Roland Jupiter-8 was manufactured from 1981-1985 and quickly established itself as the premier analog polysynth. Artists like Toto, Duran Duran, Prince, Depeche Mode, and countless others used it as their primary keyboard. Its combination of lush sound, robust construction, and intuitive programming made it the studio standard. Despite its excellence, only about 3,300 units were produced before digital synths took over the market.
Black Corporation released ISE-NIN (the name is a Japanese play on words referencing the legendary status of the Jupiter-8) as their fourth major polysynth. It continues the company's pattern of honoring legendary instruments while making them practical for modern use. The build process is similar to Deckard's Dream and Kijimi, with experienced builders typically completing the project in 60-80 hours.
The DIY community has particularly noted ISE-NIN's slightly more straightforward build compared to Deckard's Dream, making it an excellent entry point into complex analog polysynth DIY. The availability of the ISE-NIN VOICE Eurorack module also allows builders to start with a single voice before committing to the full 8-voice build.
