Classic Polysynth Character for Modern Workflow
The Safari Audio Polyrex captures the unmistakable character of early-’80s analog polysynths and filters it through a modern, streamlined workflow. Built around a square oscillator with a sub-oscillator for added weight and a noise generator for air and grit, it delivers the harmonic bite and body that defined the classic polysynth sound. From there, PWM movement, LFO pitch modulation, and a musical Resonant filter shape everything from dreamy pads and unstable tape-style keys to punchy basses, glassy plucks, warped chords, and cinematic textures. A full ADSR envelope with selectable Envelope and Gate modes gives you fast, expressive control over how each sound opens up as you play. Nostalgic in tone yet effortless to use, Polyrex delivers vintage inspiration without the fuss of physical hardware.

More movement, more atmosphere, same plugin
Beyond its core voice, Polyrex delivers modulation and effects that bring vintage synth tones to life. A built-in arpeggiator with Octave and Rate controls provides instant rhythmic ideas, while a dedicated LFO section with Rate and Delay controls adds evolving, delayed motion. Additionally, Glide delivers smooth, expressive pitch slides, and dedicated pitch and LFO performance sliders keep your hands on the shape. When it’s time to add space, a trio of onboard effects offers creative flexibility: a wide, shimmering chorus inspired by classic polysynth records, a warm analog-style delay for movement and atmosphere, and a spring reverb that lends vintage depth and dimension. Together, they make Polyrex a complete vintage-synth workstation, accessible from a single window.
