The Roland Boutique Series offers virtual analog recreations of classic polyphonic analog synths in module form, with up to 4 voices of polyphony in each unit. Each module also features a 16-step sequencer, two ribbon controllers, a built-in speaker, battery or USB bus power, MIDI/USB in and out, and mini jacks for stereo input, output, and headphones.

The JX-03 recreates the sound of the Roland JX-3P, offering all 24 knobs of the original optional PG-200 controller, which was used to make programming the JX-3P easier. The JX-03 adds more extensive cross-modulation capabilities for the second DCO, as well as new LFO and DCO waveforms and an expanded DCO range.

This price reflects the module paired with accompanying 25-key keyboard.
