Roland JX-3P

The JX-3P is something of a hidden treasure – there is more to it than meets the eye. It came out about the same time as the venerable JUNO series, but represents a shift away from the traditional analog synthesizer interface and towards a less hands-on format. The JX-3P was mostly aimed towards players looking for those great stable Roland sounds of the time, but with immediate Preset-based access to them, and only the most basic and newbie-friendly of on-board controls to adjust them. (Note the space reserved on-board for holding sheet music in place.)

That is not to say this is a dumbed down synth, but rather, the digital technologies being explored by Roland at the time allowed for greater programability while simultaneously reducing the need for dedicated hands-on controllers per parameter - a path most synth manufacturers walked down during the eighties. This means that sliders and knobs were being phased out in favor of push-buttons, fewer sliders and a powerful programming interface tucked away “under the hood”.

The JX-3P shares the same great analog filters and VCAs as the JUNO and even the JUPITER series. Just like the JUNO, it’s a six voice polyphonic feeding digitally controlled oscillators (DCOs) through analog filters, envelopes and amps. However, the JX-3P has two oscillators per voice instead of the single osc. found in the JUNO synths, and while that does allow for greater flexibility, the onboard programming interface is a lot less fun and hands-on than that of a JUNO, no doubt contributing to the popularity the JUNO series enjoys over the JX-3P. You will need the optional PG-200 programmer if you want a real hands-on experience with the JX-3P.

Surprisingly, the JX-3P is MIDI equipped, in fact it was Roland's first MIDI synth. However, its MIDI was limited to basic note on/off information only. Synths like the JUNO 106 had far better MIDI implementation. But the JX-3P also featured an on-board 128-step sequencer and came in a (slightly modified) rack-mount version called the MKS-30.

Although the JX-3P may not be as popular as a JUNO, it makes a great vintage synth capable of creating some lush, classic analog sounds. And without the cult status of other synths similar to it, they can also be found at bargain prices, making them a definite synth to consider when looking for those classic early eighties Roland sounds. And aftermarket upgrades (like the KIWI-3P) can make it just as good, if not better, than any other polyphonic analog synths out there! It has been used by The Future Sound of London, Astral Projection, Vince Clarke, Orbital, Luke Vibert, Stevie Nicks, Asian Dub Foundation, and Thomas Dolby.

If memory serves, ( and i haven't had my hands on one of these beauties for about 25 years) to get the synth out of omni all you do is depress on of the 16 patch buttons and hold it whilst switching it on, rudimentary but it worked well when the only other option was the Juno 6 that had a weird rs232 based sequencer setup. I miss this baby ; )

Afa midi, when you first turn the unit on, it is in omni. There is a trick for putting it on chan 1 only :( don't have the synth anymore ) I think it has to do with powering it up while switching the load or save switch???? Google it

it really irks me there's no mention of the sequencer anywhere in the write-up. Considering you can generally get these in better shape than a 106, it has all the programmability of the 106, and the sequencing - all for an average of half the price, i don't see how it's not a win-win for everyone. I put them right next to each other - and for strings I think the 3p sounds better.... just saying....

This has 'Ladyhawke' written all over it, and that is a good thing. Also 'The Princess Bride.' Buy one of these and fall in love with the 80's all over again.

I just got one of these babies yesterday and man does it sound sweet!! I paid $500 for the synth with the Pg 200 controller included. Fantastic analog sound! very dynamic. Can't understand why the go for this low? It's easily at the same level, if not better, than a Juno 60.
