JX‑Osc

An 80s-era analog synth — your vintage sci-fi sidekick.

Hear it

Real sounds,
straight from JX‑Osc.

Four presets and a full track — every sound below was made with JX-Osc alone.

Tap a sound. It streams, nothing to download.

The thing reviewers say

It looks playful. Then you hear it.

Every knob is drawn by hand, and the sound underneath is a real 80s-era analog synth, sampled shape by shape, run through real spaces.

“The sound here is serious… I really like it.”

What’s under the hood

Familiar sounds.
Refreshing interface.

  1. 12

    Wave shapes, three at a time

    Three oscillator selectors, each with 12 analog shapes from an 80s-era synth — plus per-oscillator pitch and pan.

  2. 30

    Convolution spaces built in

    Cross-synthesis through our favorite outboard reverbs and eurorack effects — 15 reverbs and 15 FX, ready to convolve your sound.

  3. A stepped sequencer with a twist

    It only steps when a note arrives — swapping the loaded wave shape per note to bring melodies and chords to life.

  4. 52

    The LP Pro-52 filter & full envelope

    A creamy LP Pro-52 low-pass with resonance, velocity and key tracking — shaped by a full ADSR with attack-curve and dual sustains.

  5. That signature 80s chorus

    The lush ensemble chorus that made 80s synths iconic — the sound that beams a pad straight into a sci-fi soundtrack. Plus vibrato, glide, slop and spread.
