The Roland Boutique JX-03 is a compact 4-voice synthesizer module released in 2015 as a limited-edition run. It uses Roland’s Digital Circuit Behavior (ACB) technology to model the exact sound and behavior of the 1983 Roland JX-3P synthesizer and its companion PG-200 hardware programmer.

- Modulation: Cross-modulation options (Sync, Metal, and two Ring Modulation modes).
- Filter: 24dB/octave low-pass filter (VCF) and a non-resonant high-pass filter (HPF).
- LFO: 1 dedicated LFO with Sine, Triangle, Sawtooth, and Random waveforms.
- Envelopes: 1 ADSR envelope shared across the filter and amplifier.
