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 However, as on the JX-8P, knobs and sliders have been replaced by low-profile buttons and a nice LCD display.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.

I have heard somewhere, that there is a software mod for increase the attack time. to get a sharper aggressive attack, is this thru or false.

Huge sounding, with a massive bottom end. A little brighter and wider than the JX-8P perhaps (because of differences in op-amps and chorus circuitry), but both sounds great. Mind boggling that it isn't much more expensive.

Terrific, and a 'proper' musical instrument, powerful and refined. Still ridiculously cheap compared to the fashionable classics. Master the sync settings and it will also produce very delicate acoustic like tones. Layering what amounts to two almost independent synths for each sound allows for some very detailed voicing.

Had mine since 2010 and it's still surprising me. Don't let the poor MIDI spec or lame presets put you off. PG800 if you can to get the best out of it, which will unfortunately raise the cost, or get the sysex mod.

I lucked out and picked this synth up for $300.00 from a local studio, rarely used. Along with the Patch Editor, this synth is just that: one monster of a REAL synth...with all that comes with it. Ups/Downs/Strengths/Weaknesses..........simply put, a real analogue treasure with the best brass pads on earth imho, that will take over anywhere you want to use them. HUGE SOUND!!!!

Get the Colin Frasier sysex chip upgrade, get the PG800, Kiwi or a BCR/BCF 2000 and rock this sweet machine. Presets are junk except for a few, but don't be fooled, spend some time and make your own sounds, it is a really fun machine to dig into. I program my sounds using the whole key mode so I don't confuse which sound I am editing, lower or upper. Get a MC card to save your patches on. I love the sync option to create PWM. Don't sleep on the mono or unison modes. Editing using the PARAM VALUE buttons is easy. The slower you move the alpha wheel the faster numbers move. This tank crushes!
