PolyFreq
Key Features
- Dual-oscillator analog modeled synth engine focused on basses, warm pads, aggressive leads, chords, and melody parts.
- Circuit-modeled signal path adds saturation, drift, instability, and nonlinear response for animated vintage-style tone.
- Soviet-style multimode filter provides low-pass, band-pass, and high-pass modes for broad sound shaping.
- Unison and drift controls help create wider, less static patches without needing a large modulation setup.
- Smart randomizer speeds up sound discovery when you want playable synth ideas quickly.
- Built-in character effects cover BBD-style pitch-shifting delay, granular layers, analog-style delay, reverb, drive, lo-fi, chorus, phaser, and texture processing.
Description
PolyFreq is an analog modeled software synth from Dezert Audio built for bold, vintage-leaning basses, pads, chords, and leads. It uses dual oscillators, a nonlinear analog-style filter, unison, drift, and a smart randomizer to create sounds that feel less static than a basic subtractive plugin.
The official page frames the instrument around real circuit behavior rather than sampled source material. Its signal path leans into saturation, instability, and nonlinear response, with a Soviet-style multimode filter offering low-pass, band-pass, and high-pass modes for broad tonal shaping.
PolyFreq also includes a set of character effects that push it beyond a dry two-oscillator synth. The page lists BBD-style delay shifting, granular and micro-looper layers, Memory Man-inspired delay, multiple reverb types, tube/tape/op-amp drive, lo-fi degradation, Juno 60-style chorus, MXR Phase 100-style phaser, and texture modes inspired by cassette, 80s digital hardware, and 12-bit samplers.
As checked on May 4, 2026, Dezert Audio presents PolyFreq as a free download with optional donations, while launch coverage confirms that it requires a free checkout, account creation, and email/password activation inside the plugin. Because the installer is delivered through that gated store flow, the review worktree links to the official product page rather than mirroring a private checkout file.
Frequently Asked Questions
Is PolyFreq a Kontakt instrument?
No. Although Dezert Audio is also known for Kontakt products, PolyFreq is a native software synth plugin. The official page lists AU and VST3 support rather than Kontakt requirements.
Does PolyFreq require an account to use?
Yes. Launch coverage states that users complete a free checkout, create an account, then enter their email and password when opening the plugin for the first time.
What makes PolyFreq different from a basic subtractive synth?
The focus is on analog modeled behavior: saturation, drift, nonlinear response, and a bold multimode filter. It also includes several character effects, so patches can move into lo-fi, granular, delay, modulation, and textured territory without extra inserts.
What styles does PolyFreq suit best?
Its stated range covers basses, pads, leads, melodies, and chords. The vintage filter, drift, unison, and texture effects make it especially natural for synthwave, hip-hop, electronic, ambient, and cinematic sketching.
