The MKS-70 Super JX is the rackmount version of the JX-10 synthesiser and has two JX-8P synth engines. It’s one of the defining synths of the 1980s. Complete with original PG-800 programmer

“The JX10 offers all the sound creating and shaping facilities you could reasonably want from an analogue synth. Features include:

  • Two digitally controlled oscillators, each with a range of 2, 4, 8 or 16 feet; sawtooth, pulse, square and noise waveforms with LFO and envelope modulation, plus tuning (fine tuning on DCO 2).
  • VCF (consisting of a low‑pass filter with cut‑off frequency, resonance, and LFO and envelope modulation), plus a high‑pass filter with three preset values of cutoff frequency .
  • VCA.
  • Two envelope generators (ADSR).
  • Chorus (two preset types).
  • Low‑frequency oscillator, with sine, square and random waveforms, rate and delay.

In addition, the oscillators can be sync’d or cross‑modulated for even wider (nay, wilder) tonal possibilities, envelopes can be inverted, and there are a variety of velocity sensitivity curves” – Sound on Sound

“It is possible to produce rich, fat, bright, gutsy, ethereal, sparkling and/or cutting sounds that work well with no effects — reverb, chorus or some other treatment becomes the icing on the cake” – Sound on Sound
