The Roland JX-10 Super JX, JX-8P and JX-3P are brought to life in the Syntronik DCO-X. Manufactured from 1983—1989, the JX line expanded Roland’s use of DCO – Digitally Controlled Oscillator – technology from the Juno-60, in an attempt to compete with the Yamaha DX7 digital FM synthesizer that ruled the mid-80s.
The JX models employ two oscillators per voice instead of the single oscillator of the Juno-60. This allows for classic oscillator detuning for the traditional analog synth sounds that we all know and love but also cross-modulation where one oscillator modulates the other. And while Roland added the second oscillator, they kept the beautiful chorus from the Juno-60. The JX synths are definitely fat and warm, but in a more midrangey, horn-like way than the Jupiter and Juno. This makes the JX ideal for dark pads and brass sounds in addition to its unusual FM metallic and percussive tones.
