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 However, as on the JX-8P, knobs and sliders have been replaced by low-profile buttons and a nice LCD display.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 one of these, I have a JX-8P and a JX-3P also all with programmers. The JX-8P is one of my favorite synths, it is just perfect, the JX-10 sounds identical but the way that the patches are structured is a bit different than on the JX-8 and it turned some people off. Essentially you have 2 JX-8P's working together here and that leads to some very thick and fat sounds, this thing is WARM and can also sound digital. I love it, but it does have some short falls - midi and the way that the tone architecture is set up - its just annoying, however the sound is amazing, and that's what counts.

I've just made a virtual programmer in Logic Pro for the JX-10. I always loved this synth for it's pads, but now it really opened up it's sonic potential! Programming has become very easy without having to spin the Alpha-dial 10 times, searching for parameters, etc..
I'd like to share it with you (you'll need the Colin Fraser sysex mod 2.3):

Undiscovered or long forgotten gem, better than any Jupiter and way more cheaper. Keeper!

Does anybody else find that they need to spin the alpha dial like 10 times for a change in parameter values? I mean, it takes like 10 seconds to toggle from a noise waveform to a sawtooth! Love the sound on this beast, but man editing blows.
