Roland JX-8P
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.

"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).
JX-3P sounds more 'vintage' and edgy, they compliment each other not compete.
I know some will disagree but owners who've had both know the truth.
