The Roland Boutique JX-03 sound module not only contains all of the synth power of the original JX-3P but brings with it the interface of the optional PG-200 controller. When these 2 units were combined, there was little left to the imagination. Giving the user total control to create lush, classic analog sounds on the fly, the JX-03 is here to deliver all that power, but in a solid unit the size of a book.

A hidden gem

The JX-3P is often referred to as a forgotten classic despite its easy ability to give the player instantly huge sounds. Rather than using the original button driven interface, Roland went with the deeply editable addition of the 24 knobs from the PG-200 so that you can instantly delve deep into the synth engine.

Further to this, the Roland JX-03 comes with some modern additions such as extra waveforms and extended range for both DCOs as well as extra waveforms for the LFO. The second DCO also gets extra cross modulation options which results in massive sonic capability.

Built in sequencer

The JX-03 comes with a built in 16-step sequencer so you don’t need an additional controller keyboard to begin making music. The built in ribbon controls also let you preview sounds so that you can program patches on-the-fly.

Should you wish to connect a master keyboard, you can use the optional K-25m that was purpose built to connect to the Roland 2015 Boutique range, or you can use your own keyboard via the USB or MIDI ports.

Chain Power

Like other modules in the Boutique range, the JX-03 is capable of chaining up with other units to double the polyphony and thus the output of your music. Connect 2 units and use a single controller to play whilst using the controllers of the master JX-03 to control the slave units into creating some superb sounds.

Perfect for everywhere

The JX-03 is perfectly capable of making music out and about but is just as adept in the studio. The inclusion of MIDI and the USB port mean that you can record directly into your favourite DAW and use the JX-03 as a 24-bit, 44.1 kHz audio interface. There is even an option to back up all of your favourite sounds and sequences via USB memory dump.

For performance, recording or just plain fun, the Roland Boutique JX-03 sound module is a great creative tool for all synth enthusiasts.
