Roland JX-3P 61-Key Programmable Polyphonic Synthesizer w/ KIWI 3-P Mod upgrade

This isn’t just a Roland JX‑3P — this is a Kiwi‑3P‑powered monster. The classic 80s analog tone is still here, but the Kiwi upgrade blows the doors wide open: deeper modulation, huge patch memory, dual LFOs, dual envelopes, full MIDI control, and a way more expressive, modern feel. It hits that warm Roland sound but with way more punch, movement, and flexibility.

The Kiwi‑3P (by KiwiTechnics) is a full internal upgrade board that transforms the JX‑3P into a modern‑spec analog polysynth while keeping the original tone.
