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.

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

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.

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.

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.
