The Roland Boutique JX-03 sound module continues the legacy of the JX-3P synth. The original model was launched when button-driven interfaces were popular, so it was designed to give immediate access to preset sounds. It was actually highly programmable though, especially when used with the optional PG-200 controller that added 24 rotary knobs for instant sonic sculpting. The limited-edition 4-voice JX-03 inherits all 24 knobs from the PG-200, as well as the distinctive JX tonal character. Roland has also added some extras not present in the JX-3P including new waveforms, expanded DCO range and cross modulation options. You can even slide the JX-03 into the optional K-25m keyboard unit for a self-contained, go-anywhere synth experience.

JX-3P Sound, Built-In Controller
Often described as a forgotten classic, the JX-3P was all about instant access to big sounds, with a simple button-driven interface rather than lots of knobs and sliders. When used with the optional PG-200 controller however, the power of the highly programmable engine was revealed. The new JX-03 module recreates the panel layout of the PG-200 – including all 24 knobs - giving direct and instant access to the versatile synth architecture.

Additional Sound-Shaping Options
Like the other members of the Roland Boutique range, subtle improvements have been added that weren’t found on the original models. The JX-03 benefits from 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. These additions further expand the sound creation possibilities of the battle-tested JX engine.

Develop Your Ideas with a 16-Step Sequencer
The onboard 16-step sequencer is a sonic scratchpad that lets you try out new ideas without bringing lots of gear – it can even be used without a keyboard. And if there’s no keyboard connected, the ribbon controller lets you preview the sound, making it an ideal way to program patches quickly and easily.

Works with Optional K-25m Keyboard Unit
The JX-03 works especially well with the K-25m, an optional 25-key velocity sensitive keyboard that takes your music making to the next level. Once docked in the keyboard, the module’s front panel can be tilted for convenient access to the knobs and sliders.

Chain Mode
The original JX-3P was a powerful synth featuring 2 digitally controlled oscillators for each of its 6 voices. The JX-03 features a chain mode that allows you to connect two JX-03 modules using the MIDI ports and create one, 8-voice synthesizer. Adding additional modules adds another 4 voices of polyphony with each module. This is especially great when controlling the JX-03 from a larger external keyboard. You can even edit the sound from the master module and control both units. Great for realtime filter sweeps and envelope adjustments.

Battery or USB Bus Power
Some of the best music is made away from the studio, so the module runs on 4 x AA batteries, ready for when inspiration strikes. Alternatively, you can power the JX-03 via USB bus power.

USB Audio Interface for Direct Recording into Your DAW
The built-in USB port also functions as a high-quality 24bit, 44.1 kHz audio interface, for a fast, simple and reliable way of recording directly to your DAW application. You can keep your favorite patches and sequencer patterns safe too, via the USB data backup function.
