Roland Super JX-10

Roland JX 10 Image

Released in 1985 the JX-10 (Super JX) combines two individual JX-8P's for an outstandingly warm, rich and analog sound which is still used in many modern studios all over the world. This synth was the first Roland Synth to be fitted with a quality 76 note keyboard with velocity and aftertouch. Two DCO's per voice, two ADSR envelope generators per voice, and a resonant lowpass & non-resonant highpass filters are only the beginning. It has a 12 voice polyphony for a total of 24 oscillators and it is by far one of the most programmable synths of its time! However, as on the JX-8P, knobs and sliders have been replaced by low-profile buttons and a nice LCD display. Although this may look sleek and elegant, it makes editing a chore. Assign parameters to the alpha dial for tweaking, one at a time, or get the optional PG-800 Programmer to provide traditional, hands-on, dedicated sliders for editing the JX-10's parameters.

The JX10 has a Chorus effect and a chase-play Delay function. The chase-play function allows programmable delayed repeats of voices by alternating patches of the upper and lower modules. The simple chorus effect is either off, slow or fast. It has two programmable sliders (if you don't use the PG-800) for some real-time control which can be recorded along with other effects and keyboard modes into one of the 64 Program Patches. This is in addition to its standard 50 preset and 50 user patch memory. A simple sketch-pad 1-track real-time sequencer is also on-board. It stores sequence data directly to an M16C card, or an M64C card for Patch/Tone OR sequence data. The M16C has a capacity of 400 notes, the M64C 1440, according to the manual.

The JX-10 also comes in a rack-mount version known as the MKS-70. It's worth noting that the JX-10 can not be edited via SysEx, however the MKS-70 can which is one reason many have chosen the rack version over the keyboard. The JX-10 can make bulk dumps of its sounds over sysex, but only with (discontinued) Roland M64C RAM cartridges. The JX-10 has been used by Jane Child, Pink Floyd, Duran Duran, Angelo Badalamenti, Yellow Jackets and The Cure.

@SynthFixist. Well the 3P has the IR3109 which sounds gorgeous as it did on Jupiter 8 and Juno 60. JX10 has a different tone altogether but it's nowhere near as punchy and 'pure' as a 3P. You can hear 3P all over Gorrillaz last album (Plastic Beach) the main bass riff on 'Stylo' is a low end JX-3P, I have the exact sound programmed on my 3P. JX-10 could never do that sound it's like treacle compared to 3P. Also JX10's resonance is never fully shut off even at zero, it has quite a brittle high end when you whack the res up too.

Depends on the tone you like. I personally cant stand the JX-3P..to me it's one of the worst sounding Rolands there is.

Love this site but I find it hillarious that you have the ratings for the JXs all mixed up. If anything this is the worst of the bunch for a number of reasons, even though it's by far the most feature packed.

JX-3P is a 5 (or 4)
JX-8p is one less
JX-10 is not as nice as 8P and both are completely different to 3P.

I know it's all just so called opinion, but 3P SOUNDS like a vintage synth, DCOs never sounded so good + much better filter/chorus than in the 8P and 10.

But 8P is also great for it's differences, 10 is just a bridge too far and was one of Roland's worst designed synths (full of bugs and flaws).

If you can't settle this nor read general opinion on the net about how amazing the little 3P is, I suggest you stick all 3 JXs at 4 stars and leave it there. Don't just give a star rating based on press release and apparent features, the SOUND is first, then the stability/experience.

"I've revisited the JX10 since these experiences, but have not changed my opinion. The cartridge/clock problems might well have been confined to my particular synth, but I still find the flawed MIDI implementation and the concept of shared tones (which should be punishable by law, in my opinion) to be very frustrating problems. How could Roland get it so wrong after the beautiful simplicity of the JX8P? Paul Ward" (sound on sound magazine)

I have 2 Super JX-10's and a MKS-70. The MKS 70 is not thinner at all, it has more clarity in the top end. If you dial back on the top end there is basically no difference in tone or phatness of the rack with it's keyboard brothers. Both versions are super underrated analog monsters that can sound like many other synths (a big big plus)!!!!!
