Boutique JX-08 Virtual Analog Synthesizer Module

Back in the '80s, the JX-8P brought a sleek, programmable edge to analog synths with its PG-800 programmer panel, letting players dial in exact tones that defined countless tracks—and this module nails that same vibe in a pint-sized package.

At its heart, it's a digital recreation of the JX-8P's dual digital oscillators, classic filter, dual envelopes, and LFO, now boosted to 20-voice polyphony for thicker chords and layers. You've got hands-on knobs mimicking the original programmer for real-time tweaks, plus bi-timbral operation with dual and split modes across two parts. A 64-step polyphonic sequencer holds 128 patterns with motion recording and random generation, an arpeggiator for instant grooves, and 17 effects like JUNO-106 chorus, SDD-320 reverb, lo-fi comp, and pitch shifters. Connections include stereo audio I/O, headphone out, full-size MIDI, USB-C audio/MIDI, and external clock— all in a sturdy metal-front chassis measuring 300 x 128 x 47 mm and weighing just 2 lbs, powered by four AA batteries or USB-C, with a built-in mini speaker for on-the-go jams.

Players love how it captures the JX-8P's warm, evolving pads and leads with modern reliability, though some note the sequencer could use more voices per step for denser programming. It's a Boutique standout, perfect for stacking in a rack or pairing with the K-25m keyboard.
