Origins
Roland introduced the Juno series in 1982 with the Juno-6, establishing what would become one of the most influential synthesizer lines in history. Designer Roland Corporation, under the direction of their engineering team led by key designer who created the DCO (Digitally Controlled Oscillator) technology, sought to create affordable polyphonic synthesizers that maintained professional sound quality. The Juno series succeeded spectacularly, defining the sound of 1980s pop music.
Design & Technology
The Juno-6 and its successor Juno-60 (1982) featured six-voice polyphony using DCOs for tuning stability, a single analog voltage-controlled filter with envelope and LFO modulation, a high-pass filter, and a chorus effect that became the Juno's signature. The 61-key keyboard supports portamento and a simple arpeggiator.
The Juno-106 (1984) added MIDI capability and increased memory to 128 patches. It replaced the arpeggiator with a more capable one and added separate VCA and VCF envelope generators. The 106 became the definitive Juno, selling approximately 100,000 units.
All Junos feature the distinctive Roland chorus—a lush stereo effect created by modulating delay lines that contributes significantly to the instrument's spacious sound.
Production History
Roland produced the Juno-6 (1982), Juno-60 (1982-1984), and Juno-106 (1984-1988). The Alpha Juno series (1/2/HS-10/MKS-50) followed with different interfaces. The 106's longevity and sales made it the definitive Juno model. Roland has revisited the Juno concept with the Juno-D, Juno-G, Juno-DS, and Boutique JU-06/06A, though these are distinct instruments sharing only the name.
Notable Users
The Juno's user list encompasses virtually every 1980s pop, new wave, and synth-pop act: Duran Duran, Tears for Fears, Wham!, A-ha, and countless others. Its warm pads, punchy basses, and distinctive chorus defined an era of popular music. The 106 remains widely used in contemporary productions for its classic analog sound.
Cultural Impact
The Juno demonstrated that affordable polyphonic synthesizers could achieve professional quality, democratizing access to analog synthesis. Its chorus effect became so iconic that software emulations are standard in DAWs. The Juno sound remains a reference point for analog emulation, with countless plugins and hardware attempting to capture its character.
Market & Collectibility
Juno-60s command $2,000-$4,000 depending on condition and modifications. Juno-106s typically sell for $1,500-$3,000, though voice chip failures affect many units and require repair. Original Juno-6s are rarer and command similar prices to the 60. The Alpha Juno series is more affordable at $400-$800. The Juno is essential for any serious vintage synthesizer collection.
