Welcome to All Music Inc's Musicdungeon, you are looking at a great piece. 
This is the 1985 Roland Japan Juno-106 61-Key Synthesizer.
The Juno is an institution unto itself, used by everyone from Depeche Mode in the 80s to EDM artists of today.
The Juno-106 is a programmable, six-voice polyphonic, analog, subtractive synthesizer. 
With its relatively simple voice architecture, it is able to produce luscious soundscapes, rich basslines, strings, pads, pianos, leads and percussive sounds. 
Its intuitive interface and diverse sonic palette has inspired musicians from all styles and backgrounds.
The Juno-106 uses six digitally controlled oscillators, capable of producing a sawtooth, pulse and sub-octave square waveforms. DCOs were introduced into Roland synth design during the 1980s, as a means of eliminating inaccuracies such as pitch drift, which arose from the use of the completely analog VCOs in earlier synthesizers. DCOs provided a cheaper and more stable alternative to VCOs, without compromising the overall sonic character of the instrument’s analog sound. These were the same kind of control oscillators that were used in Roland’s famed JX-3P synthesizer.
The sawtooth waveform of the Juno-106 outputs directly from the DCO core, while the pulse wave is derived from the sawtooth, via a wave-shaping circuit. Even though these oscillators are digitally controlled and digitally stable, they produce true analog outputs with no digital stepping. Pitch is selectable via 16′, 8′, and 4′ settings. A square wave sub-oscillator and a noise generator are also provided, with individual sliders to control the levels for each parameter.
The Juno-106 features control for pulse width modulation (PWM). When the PWM switch is set to MAN, the pulse width can be manually set to a certain ratio. In this setting, the PWM slider controls the actual pulse width. When the PWM switch is set to LFO, the pulse width is controlled by the LFO signal. The PWM slider now controls the intensity of the LFO modulation.
The Juno-106 offers two Assign modes – Poly 1 and Poly 2. Poly 1 turns the Juno-106 into a six-voice polyphonic synthesizer, assigning one synth voice to each key that is pressed. This particular setting is generally suited to sounds with envelopes similar to a piano or a guitar and is recommended for standard use. Poly 2 mode is similar to Poly 1, the key advantage being that only the last note or notes played receive natural release length. This makes Poly 2 mode more suitable for performance with the onboard portamento effect. Pressing Poly 1 and 2 moves the Juno-106 into Solo Unison mode. In this mode, the Juno-106 acts as a monophonic synthesizer, with all six voices assigned to each key that is pressed.
Perhaps one of the most revered features of the Juno-106 is its 24dB/octave analog low-pass filter, which provides the instrument with much of its distinctively smooth texture and deep sonic power. The voltage controlled filter (VCF) features adjustable sliders for frequency and resonance level and can be modulated by one of the envelopes, the LFO, and keyboard tracking. Individual sliders for ENV, LFO and KYBD control the modulation level of the three sources. Using the KYBD control, the filter cutoff can track the keyboard, allowing for higher harmonics to be heard on notes with higher pitches.
The VCF has self-oscillating abilities, making it a vibrant and diverse analog filter. In addition to this, the Juno-106 also features a non-resonant high-pass filter (HPF), with four control positions and a dedicated slider for cutoff frequency.
The VCA of the Juno-106 can be switched between simple note gating or envelope controlled loudness, via a switch on the faceplate. A single invertible ADSR envelope can be assigned to the cutoff frequency of the filter, and can also be selected to control the VCA. A triangle wave LFO features controls for rate and delay and can be applied to both the DCO and VCF sections.
This Juno is in very good overall condition as you can see in pics- typical marks from age and normal use.
Fully tested and works as it should.
Includes the Hybrid case in pictures in fair/good condition.
This is your chance to add a Roland classic to your studio.
