Launched in 1982 as the very first in Roland's beloved Juno series, this synth kicked off a legacy of warm, versatile analog sounds that defined countless 80s tracks, bridging the gap between experimental Jupiters and more refined later models.
At its core sits a single DCO per voice delivering sawtooth, pulse, and square waveforms with PWM—switchable between envelope, manual, or LFO control—plus a sub-oscillator and noise for added depth, all feeding into a smooth high-pass filter and resonant 24dB/octave low-pass VCF with extensive cutoff, envelope mod, and LFO options. A single ADSR envelope shapes the VCA, while the LFO offers adjustable rate (0.3-20Hz), delay up to 214 seconds, and a unique manual trigger button for precise vibrato bursts. Hands-on sliders and switches cover everything from arpeggiator modes to key transpose and dual chorus modes that thicken tones beautifully in stereo. Built sturdy at 1060x378x113mm and 11kg, its 61-key velocity-sensitive keyboard pairs with a spring-loaded bender lever (±fifth on DCO, deeper on VCF) and rear jacks for pedal sustain, VCF control, and balanced outputs.
Players cherish its rock-solid tuning—DCOs stay phase-locked and stable even as the master drifts—and that immediate, no-menu tweakability, though many note the lack of patch memory means dialing in sounds from scratch each time. It's earned a cult following for lush pads, evolving arpeggios, and a raw character that's tough to emulate digitally.
