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 However, as on the JX-8P, knobs and sliders have been replaced by low-profile buttons and a nice LCD display.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

JX-10 has 24 oscillators actually.

jupiter 12 voice polyphony means it can play 12 notes at a time. Even though it has more voices than a jp8 it cant even compare to one. The JP8 has 16 oscilators (and they were the fat sounding early 80's ones).

As previous poster Andre said, this thing is a moster pad and string machine! The velocity and after-touch sensitive keyboard is really great for strings - you'll be amazed when you hear what it can do. I've owned mine for the best part of a decade and I still use it regularly. It lets itself down a bit with it's bass and lead sounds though. It's also a shame that it suffers from the same fate as all JX synths and really needs a dedicated programming module. That being said, I don't have one and I can still programme it perfectly well, though it's a bit tedious!

With all the respect to David, I'm not sure he knows exactly what 12 voice polyphony means... Gosh, this is the analog synth with the largest polyphony available at the time ! Even monsters like the Jupiter 8 had only 8 voices ! Noise is a common problem on old analog synth and can be solved by some maintenance really (reacap). It's a beautiful sounding analog synth, and very powerful. The JX8P seems to sound a tad fatter though. The sequencer is only applicable when a cartridge is engaged. The keyboard is one of Rolands best ! With the reasonably low price the go for today, anyone should grab it !
