Dezert Audio is giving away PolyFreq, an analog-modeled polyphonic synthesizer that recreates the character and instability of real hardware. Built around dual oscillators, a non-linear analog-style filter, unison, drift, and a smart randomizer, PolyFreq is engineered to add weight, movement, and width to lead lines, chords, and basses without sounding clinical.
What is PolyFreq?
PolyFreq’s analog modeling deliberately leans into the imperfections that make hardware synths sound alive — slight tuning drift, voice-to-voice variation, and non-linear filter behavior. The result is a polyphonic engine that sits in a mix the way a vintage synth would, rather than a sterile, perfectly stable software voice. The unison and drift parameters give you direct control over how loose and wide the patches feel, and the smart randomizer is a fast way to surface starting points that you would not have programmed by hand.
