Roland JX-8P

Roland JX-8P Image

The JX-8P is a decent analog polysynth. It has 6 voices of polyphony, great MIDI implementation and patch storage as well as an external memory cartridge slot. Though it is far more advanced than its predecessor, the JX-3P, the JX-8P has its drawbacks. Hands-on programming is sacrificed and reduced to assigning the parameter you want to tweak to a data-slider near the pitch/mod bender. Enter the PG-800 controller which gives you total control of all the JX-8P's editable parameters with hands-on traditional slider control. Membrane buttons dominate the front panel of the JX-8P providing access to the various preset and user patches and to page through and assign editable parameters.

Professional features can still be found under the hood of the JX-8P. Its 61 note keyboard is velocity and aftertouch sensitive. Just like the Juno synthesizers it uses DCO's for a very stable system, however its sounds are a little thin and bright. It also features portamento, unsion and solo (monosynth) performance modes. It is used by Biosphere, 808 State, Tangerine Dream, The Shamen, Depeche Mode, Überzone, the Cure, Go West, Ozric Tentacles, Future Sound of London, Jean-Michel Jarre, Europe, and Jimmy Jam.

"although it was a far more powerful and flexible synth than the Juno, it lacked the same degree of mass-market appeal. In part, this was caused by Roland's eagerness to present their new flagship keyboard synth as competition for the DX7. "

"Together with its PG800 programmer, it was a flexible and accessible synth, and thanks to innovative little tricks such as the ability to link the volume of DCO2 to the keyboard velocity (which is useful when the oscillators are sync'ed) it generated a wide range of new powerful sounds. also excelled at Roland's traditional strong suits — strings, brass and pads — and many of its factory presets have remained part of the standard synth vocabulary for the ensuing two decades."

See the JX-3p page for a quote from the same article about that synth.

"There were also two superb new synths, the Juno 106 and, although few remember it as such today, the replacement for the Jupiter 8, the JX8P"

Yes the 'intended replacement' for the Jupiter 8 was the JX-8P (I always felt JX meant Digital Jupiter - the 3P can sound very close to a jupiter 8 sometimes).

These actually have a wide array of useable factory sounds. The PG-800's command a lot of money, too much in fact. I use external processing gear to get more out of the built in sounds. Very easy to use save for programming it. These keyboards are an absolute bargain and most I have found are in excellent condition. Get one. Do it now!

It's more versatile than the 3P and Juno (any variety). It excells at warm/lush strings and pads and can also do some good bass sounds (Not FAST envs but still good). Overall a very powerful and immensely under rated synth... a bargain today simply because it doesn't have built in knobs and sliders (get a programmer - ANY will do not just the official, get a cheap 2nd hand BCR and you have full control!)

JX-3P sounds more 'vintage' and edgy, they compliment each other not compete.

does this have a fatter/warmer or sterile sound compared to the JX-3P and the Juno 60? It would be cool to know more details about how do they compare strictly sound-wise, beside programmability issues.
