Super JX and the MPG-7X

  / starskycarr   The Roland Super JX (MKS-70 / JX-10) is one of Roland’s most underrated analogue polysynths. Released in 1986, it was effectively two JX-8P synth engines in one instrument, giving you 12 voices of DCO analogue synthesis, huge pads, powerful basses, and classic mid-80s Roland character. In this video I take a deep dive into the Roland MKS-70 Super Jupiter rack synth, paired with the Retroaktiv MPG-7X programmer and the Vecoven PWM upgrade, which massively expands the capabilities of the original synth. We explore how the controller transforms the experience compared with the original menu-driven interface, and look at the additional synthesis power introduced by the Vecoven upgrade including true PWM, additional envelopes, extra LFO, and expanded modulation routing. Along the way I demonstrate a range of sounds including pads, basses, evolving textures and layered patches, showing why the Super JX became famous for its huge analogue pads and rich detuned sounds. I also look at some of the performance features of the MPG-7X such as assignable controls, patch generation, chord mode, velocity crossfading and MIDI integration, which make this combination feel like a modern analogue synthesizer despite the vintage hardware. If you're into vintage Roland synths, analogue polysynths, or classic 80s synthesis, the Super JX is a fascinating instrument sitting right at the transition between the analogue era and the rise of digital synths like the DX7.
