Jupiter-6

KeyboardAnalogPolyphonic

One of the first synthesizers to speak MIDI, this 1983 classic demoed the protocol at NAMM by jamming with a Prophet-600, kicking off a revolution in gear connectivity.

Its analog heart pumps through 6 voices with 2 VCOs per voice—saw, square, triangle, pulse, noise—offering sync, cross-mod, PWM, and unison stacking up to 12 oscillators for thick leads or polyphonic pads. A multimode filter (24dB low/high-pass, 12dB band-pass with resonance) pairs with dedicated amp and filter ADSR envelopes, plus dual LFOs for rate, delay, and waveforms like triangle, saw, square, or random. The 61-key keyboard splits for dual arpeggiators (up to 4 octaves, independent upper/lower), poly glide or glissando, and performance tricks via sprung pitch/filter bend lever, wide bender (+/-3 octaves), and modes like Poly-1/2, Unison, or Solo. Hands-on controls cluster synth params up top, memory below, with master volume, headphone out, XLR/phone stereo outs, MIDI In/Out, CV/gate/pedal inputs—all in a sturdy 106cm-wide, 16kg frame sipping just 30W.

Players love its reliable workhorse vibe for ambient drones, lush pads, bass, and zaps, often calling it a hidden gem versus the pricier Jupiter-8. Some note the plain finish and basic MIDI (no channel select or full bend/mod support), but that raw programmability—48 tones, 32 patches—keeps it a studio staple.
