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 However, as on the JX-8P, knobs and sliders have been replaced by low-profile buttons and a nice LCD display.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

Thanks. So I won a JX 10 on Ebay. On the day it arrived, the singer in my band just randomly happened to trash pick a JX-8p and bring it to rehearsal for me. It works! Now I get to compare them both side to side. Life is great!

@jimmy: Thoughts on that? There's only one thought to be had: if you can get this thing, get it. It's a very capable machine that can turn out a pretty wide range of excellent sounds. (For your strings/pads/brass, check out SynthMania's demo recordings of the MKS-70 - it can definitely crank out the analog strings and brass!) I'm still saving to buy one from a guy in my area, but having gotten to play it beforehand, I can tell you that it's absolutely worth having.

Thanks for the info. I'm looking for a board for my new setup to be used only live for strings/pads and some ripping synth brass. I can hear the metallic brightness and thought this baby may just be the ticket.
