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 However, as on the JX-8P, knobs and sliders have been replaced by low-profile buttons and a nice LCD display.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


Overall, the JX-10 is difficult to fault sonically or as a performance instrument. The Alpha dial is, of course, economical but if you can't get on with it the PG-800 Programmer isn't too expensive an accessory. Dumping sounds and sequences to cartridge is expensive but those entrepreneurial folk at Skyslip are coming up with a cheaper alternative to Roland's own cartridges I am reliably informed, just as they did for the Yamaha DX7.

The JX-10's keyboard is very pleasant to use - a little firm for the school of cheap plastic keyboard lovers but sufficiently resilient to give the pianist something to work with, so the JX-10 could be favoured as a mother keyboard. Fast and easy to use on stage, its sequencer and Chase-Play facilities both represent a significant bonus.

Unfortunately, the JX-10 is bound to suffer in sales terms with the velocity and pressure-sensitive Alpha Juno 2 at only £799 and the splittable Yamaha DX21 at £700 or so. Is there room left in today's market for a £1900 analogue synth? Roland obviously think so. If there is, the JX-10 deserves to be it.
