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 However, as on the JX-8P, knobs and sliders have been replaced by low-profile buttons and a nice LCD display.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

Just been bangin' on a pristine JX10. Picked this up yesterday so just a 1st impression review here. OMFG! Nice. Really nice. Best atmospheric/pad synth I've come across. Georgeous. Chase play & dual modes add depth & character compared to 8P (had a couple over the years). Does BIG BASS too! DCOs are actually analogue oscillators, w/ pitch digitally controlled. Load of rot about them being digitally generated & cold. Yes, MIDI spec a tragedy but what a sound. Upgrades available online for the believers.
4 Osc dream synth. Warm, silky, rich, deep. Yup.

I have big plans for this synth.

I just picked up one of these synths, and it sounds beautiful.I am having a little bit of trouble with the programming though. Can Any of you guys tell me how to start with a blank tone? How can I build a sound from the ground up? Thanks alot.

I am a regular piano player and recently came in possession if a JX 10. Can anyone help or inform me if there is a manual that I can get to learn how to use its best potential?

The JX10 is bit of a hit and miss, the sound is rich but the way the tones and patches are organized doesn't really work well, it is not straight forward. In spite of having the same sound engine as the JX 8, they don't sound exactly the same, the JX-8 actually sounds better and is more fun to program. Having 76 keys is a huge bonus though and I use it as my main keyboard controller and I use it for the warm sounds it can create also, right above it I have my JX-8 and above that I have my JX-3. The JX-8 is the best sounding DCO synth of all the Roland's, even the Juno 106 - yes I said it!
