Jupiter-8 is an iconic performing synthesizer with an all analog signal path (VCO + VCF + VCA) created by Roland in 1981. It has 8 voices of polyphony, 2 parts of timbrality and features 2 VCOs per voice. The LFO produces triangle, square, saw and random waveforms. There are two ADSR envelopes one of which is for the VCF represented by 2-pole/4-pole resonant low pass and non-resonant high pass, while the second envelope is for VCA. The instrument appeared on the market in 1981. The flagship synthesizer of Roland didn’t feature MIDI although some versions of Jupiter-8 offer DCB interface allowing for interaction with other Roland products.
The synthesizer has a 5-octave keyboard with aftertouch.
Considering 8 voices with 2 oscillators per each the synth delivers a thick sound based on 16 oscillators. The osc section produces triangle, saw, pulse, square and there’s also a noise generator offered. Unison mode allows for stacking all of the 16 oscillators onto one note and if more keys are held the synth would divide down which is a unique feature of Jupiter-8. Memory features 64 patches.
The programming is easy and intuitive, there are many sliders, knobs and buttons presented on the front panel. Jupiter-8 provides with one of the best analog sounds ever heard. The possibilities include keyboard split, layering, cross modulation, oscillator sync. There’s an arpeggiator onboard. The instrument comprises such features as adjustable polyphonic portamento and a hold function.
The connectivity features balanced stereo XLRs outputs and unbalanced 1/4” outputs.
Jupiter-8 was used by Dire Straits, Damon Albarn, Phil Collins, Duran Duran, Michael Jackson, Madonna, The Prodigy, Queen, Talk Talk, Tangerine Dream, Tears for Fears and many others.
Today Jupiter-8, as well as other synthesizers of the leading Japanese company, is a desirable purchase for those collecting music instruments. The secondary market price of the unit in good condition easily reaches $10,000.
