It might look like a toy keyboard with its colour scheme, but it’s certainly well built, and for all that weight it also weighs in heavy for sound possibilities and quality. 

 

It is an underrated vintage synthesizer, but lacking in hands-on control and an exemplary midi implementation, to be fair it was Roland’s first venture into MIDI synths, all of which one can upgrade as mentioned below.

The unit itself is relatively heavy as were most of the keyboards of the day, inside a mix of wooden bottom, top what appears to be steel on hinges that opens up and away from you revealing the boards inside, and plastic end cheeks.

On the surface of the synth, there is a layout for the rather pricey PG-200 the original controller allowing you to tweak all the synths parameters these can be found on eBay occasionally for around £200-£400 UK Sterling. If you think that I picked my JX3P up for around the £250 mark then up to £400 is pretty steep for a midi controller, also you will need a special DIN cable that is not the standard midi connector, again found on eBay.

Once you have something to control it with then, wow you can have fun with all its other parameters and of course its analogue filter that is meant to be the same as in the Juno and Jupiter series synths.

As mentioned before the midi is somewhat limited and to just on/off information.

The unit does have a built-in 128 step sequencer, which is fun, and you can get some cracking sounds from it, all classic Roland analogue sounding, strings, pads, bass, brass, effects, pretty much any analogue synth sounds you can think of, (its bass sounds surprisingly deep).

If you want some fantastic new features and a proper midi implementation then Kiwi Technics have created a chip upgrade that gives you the following features to bring the unit up to date (A full list can be found on the Kiwi Technics website): https://kiwitechnics.com/jx3pupgrade.htm

 

FINAL WORD:

A lot of synth for the money well worth checking out, and if you can afford the KIWI technics PE controller or the Roland PG-200 controller you will be having fun for years to come!
