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 However, as on the JX-8P, knobs and sliders have been replaced by low-profile buttons and a nice LCD display.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

New to the synth world and just bought one of these. It's pretty difficult to program, but whats nice is you can save your patches and tones that you've created easily to the cartridge. Dying to find a pg-800, but they're a needle in a haystack. This keyboard is great, however it does not arpegiate, but i have a microkorg xl for that. This is a pretty complex keyboard, i was shooting for something of the juno series, but i got a really great deal on this one. Definitely an overlooked synth that is very cool! I have alot to learn about this instrument.

After owning just about all of them over the years, I still feel the JX10 is the best sounding Roland poly analog I've ever worked with. It's sawtooths and pads are so choice I was finally confident enough to recently let go of my trusty JP-8, OB-Xa, and ESQ-1 (don't knock it...its a killer synth). With the new sysex bugfix ROM and PC MIDI patch editor, this and my Kurzweil are the only 2 physical keyboards I'll continue to use as sound sources in addition to live and composition work.

It sounds terrific. I've only just started using it. It sounds very close to the Jupiter 8. The presets are cheesy if you want real acoustic, don't use it for that. Start to change them and you get some really interesting sounds. Very electronic.

One of the best sounding polyphonic synthesizers ever made is the JX10,many people do not know or want to program this beast,spend some time with the stupid way of programming your own sounds can reward you with the most best synthesizer sounds of al Time!!
Sure the MIDI is very limited and JX8 has alot better MIDI,but for electronic music this synth is a incredible monster!
A classic synth,a winner,wich has a sound of its own,no VST comes even close,even many,many analoge/virtual analoge hardware polysynths of the past and present comes not even close,this is one of the best sounding polyphonic synthesizers ever made,Roland's last treu analoge synthesizer:The SUPER JX-10!!

@Analogika I also have a Polysix (And 8P along with my 3P) and they ALL sound different. They each do things the other can't. The polysix is obviously lovely sounding, but the 3P has an edge when it comes to more advanced sounds and still manages a vintage tone (just not as thick, wooly and warm as the Polysix) and I use the 8P for immense pads and strings.

It's just the JX-10 I have a problem with as it's too damned fiddly with it's tones and poor midi spec. The other 2 + polysix are all 10/10 for me for different reasons.
