Product Description

Continuing the legacy of the JX-3P synth, the Roland Boutique JX-03 module has extra waveforms and extended range for both DCOs as well as extra waveforms for the LFO. 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 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 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 K-25m keyboard unit (sold separately) 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 Boutique range, Roland also added a few subtle improvements 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 real-time 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.

What is your opinion of this product?
For $200.00 a full blown 2 oscillator synth with full control of one knob per function. Add to this a built in delay and chorus and you have a powerful synth for the price of a toy. Compare this to....nothing else like it. Roland's ACB is a great leap in digital too, all this technology and the great sound, deep and pure, fantastic! This synth is better than the 80's version with full control without menu"s. Back in the late 80's buying a digital synth meant menu diving and tiny displays of two short lines, this synth has NO menu's tweek and design in 1/10 the time of the old version. The synth stands on its own today as a great synth to design sound. Who cares about presets, you don't buy a synth like this for the presets, you delete them and build your own sound, and this synth sounds as big as any synth.

I love this thing
What is your opinion of this product?
Great build! Thought it was going to be more plastic than metal. Wrong! The body and the chaise are great. The ribbon controllers are a little cheap but not to bad. GREAT sound and ability to shape said sounds.
