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 However, as on the JX-8P, knobs and sliders have been replaced by low-profile buttons and a nice LCD display.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

Its not 2 individual JX8Ps in one, difference is coming from chorus units in it - thats not at all the same as JX8P has.

I bought my JX-10 right when they came out and I still have it! Some of the greatest string sounds ever. I also still have my MKS-70 and my D50, Yamaha dx7 and I just bought a Korg m1 used for the great crisp piano sounds(unfortunatly the other synths kind of lack that) I bought everything new except for the Korg and when I was performing live I would midi them all together to create my own sounds; it was pretty tricky live as if you didn't get the volume of each sound at the exact tone you wound up with a whole new sound! I loved it and would never sell any of my keys!

I loved my JX-10, but a total pain to program with out the external programmer.
While the filter is bit harsh, Roland (analog) synths have the ability to sit well in
a mix, both live and in the studio, giving them a kind of unique edge over what
I would consider better sounding instruments. I will say, you did feel like a pro
when you played this. Why everyone was in a rush to design synthesizers that
looked slick ( no knobs or faders ) always seemed strange to me. I felt like I
had to take a step down to get something more programable.

Mine arrived today! The sound is everything I thought it would be, but it is a pain to program. You can't even use the control sliders to adjust the filter. I will probably get the MIDI upgraded as an alternative to buying the PG-800. Even with all its flaws, it is still more than worth it for the sound!
