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 However, as on the JX-8P, knobs and sliders have been replaced by low-profile buttons and a nice LCD display.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

There are only 3 models of synth that I ever bought 2 of...The JX-10 is one of them.
There were few machines (for the price) that came close to it back in ´86....Still a valid synth to this day!

I really think that the JX-10 is a classic. I use it all the time in my music (soft house). I would rate it 80%, but how do I rate the synth on this site?

I own this synth too along with the PG800. For the money it's a great deal that deserves a lot of attention. Sweet luch pads, excellent brass and it can also create some very interesting percusive sounds. I hate the layering function of the sounds and of course in doesn't transmit or receive sysex unless you've done some kind of mod to it. Mine doesn't.

Hey JX Lovers!!
I have also this Synth and have many problems with Midi. BUT NOW I HAVE FOUND THIS SIDE:
http://www.colinfraser.com/jx10/jx.htm
He write this:
"UPDATED 18/2/09: I have now completed and tested my modified sysex code on version 2.3 of the JX10 assigner code. This is the most up to date version of the assigner code.
This file is a zip of binary dump of the hacked version of the JX10 firmware(.........)This is the latest version, based on the v2.3 JX10 firmware."
Yes!!!!! You must only change the EPROM and the JX runs with Midi. Cool!
I have it not testet yet. (Sorry my english is not good, i know)

Lovely synth but got to say the JX-8P is better 'hands on', not as quirky with it's midi, easier to program (from a non layering standpoint) and warmer due to earlier op-amps (I believe this is why it sounds a tad fatter/less sterile).

However, the SuperJX is certainly the best looking of all the JX synths and a flagship monster! (my favourite JX is the JX-3P but that's another story entirely)
