PolyRex - Vintage Polyphonic Synthesizer Plug-In

Inspired by some of our favorite analog polysynths from the early 80s, POLYREX was built around a simple idea: make a synth that feels immediate, fun, nostalgic, and filled with inspiring sounds.

We loved the spirit of classic Japanese polysynths: the glowing chorus, the drifting movement, the soft-but-punchy filter, and the way one simple chord can suddenly feel emotional.

But we didn’t want to build a museum piece. POLYREX is our version of that world, pushed through the weird, colorful Safari lens. Faster, stranger, more playful, and made for modern producers who want to create instead of menu dive.

From dreamy pads and unstable tape keys to punchy basses, glassy plucks, warped chords, and cinematic nostalgia, POLYREX gives you vintage-inspired poly synth sounds with its own Safari personality.
