POLYSUN
The Completely Free Analog Colossus
Vintage polyphonic heritage, cinematic brass, and Solina strings fused into an expressive virtual instrument.
“Ten years in the studio and a lifetime obsession with classic hardware led to POLYSUN. I wanted a synth that delivers massive low-end punch, lush vintage warmth, and unmistakable soul, all in one place. It’s completely free for the community. Go make something unforgettable with it.”
Designed for tactile depth and harmonic presence.
Every module in POLYSUN has been crafted with hardware-grade precision, delivering immediate visual feedback and the warm, uncompressed authority of classic analog circuitry.
Three Legendary Instruments in One Monster Synth
Experience the sheer power of three iconic instruments playing together in perfect harmony: a massive analog synthesizer for roaring leads and deep sub-bass, cinematic brass that bursts through any mix, and lush, silky strings wrapped in vintage chorus. Packed with hundreds of production-ready presets, POLYSUN gives you immediate inspiration and unmistakable analog soul.
Dynamic Step Modulator & Sidechain Duck
From kinetic sidechain ducking to evolving polyrhythmic patterns — sculpt cutoff, timbre, pitch, and stereo dimension with musical fluid control.
500-Series Modular FX Rack
Curate your sonic path with modeled 500-series modules including magnetic tape saturation, optical dynamics, flexible series/parallel routing, and vintage drive.
Performance XY Matrix
Take command of your sound in real time with four multi-assignable Kaoss-style XY touchpads. Seamlessly morph filter sweeps, space dimensions, wavefolding, and modulation depths with tactile hardware response.
Precision Scope & Stereo Imaging
Real-time dual-trace waveform monitor, Lissajous phase scope, and FFT spectrum analyzer with stereo correlation tracking for perfect mix balance.
Performance Zen Mode
Strip away technical readouts. Immerse yourself in a generative, living visual universe that breathes in sync with your playing dynamics, touch velocity, and MPE expression.
Expressive Control & Circuit Ageing
MPE Polyphonic Expression
Every voice responds autonomously. Modulate bow friction on the Trident string ensemble, open resonant 24 dB/oct brass filters with Silence Note triggers, or introduce individual note vibrato through key pressure.
Analog Circuit Drift
Master Spatial Acoustics
Broadcast stereo cross-feed delay and high-density shimmer reverb with infinite decay damping, modulation diffusion, and tape high-frequency attenuation.
Sound in Motion
ARP Berlin School Tangerine
Hypnotic Berlin-school step arpeggio with resonant vintage filter modulation
BASS Solid Sub Classic
Heavyweight analog sub-bass with dual-oscillator warmth and low-end punch
BRASS Chariots Of Fire
Iconic Vangelis CS-80 multi-trigger saw brass with soaring harmonic presence
KEYS Melodica Blow Reed
Expressive acoustic reed texture responding to dynamic touch and key pressure
PAD Stone World
Expansive cinematic solar pad with three-phase chorus drift and infinite air
SYNTH Triton Nitrogen Geysers
Evolving extraterrestrial modular textures with reactive harmonic modulation
