The Roland Boutique JX-03 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. Weâ€™ve 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.
