The Jupiter-8, or JP-8, is an eight-voice polyphonic analog subtractive synthesizer introduced by Roland Corporation in early 1981. The Jupiter-8 was Roland's flagship synthesizer for the first half of the 1980s. Although it lacked the soon-to-be standard of MIDI control, later model Jupiter-8s did include Roland's proprietary DCB interface, and all of them sported advanced features and the ability to split the keyboard into two zones, with a separate patch active on each zone. Features include adjustable polyphonic portamento and a Hold function for infinite sustain of notes and arpeggios. A versatile arpeggiator can be synchronized with external equipment by using the proprietary Roland DCB interface, clock input via CV jacks on the rear panel, or one of the aftermarket MIDI kits from Encore or Kenton. An assignable bender can be used to control pitch or filter frequency. From the factory, the JP-8 could store 64 patches. Patches could be stored to, or loaded from, a standard analog tape/cassette. The Encore JP8MK MIDI kit doubles the patch memory to 128[1] and enables the JP-8 to store and recall patches over a MIDI connection, using a computer with sysex utility software. The Jupiter-8 includes balanced stereo XLR outputs as well as unbalanced 1/4" outputs. In addition to monophonic and polyphonic modes, the Jupiter-8 includes a unison mode, in which all 16 oscillators can be stacked into a single monophonic patch.


Moog One

...who have amassed a decent vintage collection, new Moog things seem overpriced and uninteresting. But for everybody else without a special Jupiter 8 it is still appealing. I like new Moog stuff. I like the artists that feature in their videos and play at Moogfest. It seems a bit of a waste of energy to actively...

BEWARE: AVOID Encore Electronics

I'd never wanted to have to write this post, but unfortunately I had to. The story: I had a Roland Jupiter 8 without MIDI, and as I wanted to add MIDI capabilities to my synth, I chose the Encore Electronic's JP8MK. Very promising on paper, with a not a so complex installation procedure, reasonably priced...

Objective qualities of high-end reverb? big thing in keyboards. Digital sampling of the actual instrument. All those sampled EP's. I'm tired of them. The Jupiter 8 on the other hand, I can kick on, and that true analog buzz saw never gets old. Taking it right from the source. I was never satisfied with the digital technology, but...
