PolyIvoks Filter is a standalone and AUv3 plug-in developed by RRS OOO. This time-limited demo version allows you to experience the legendary Soviet analog sound for 5 minutes of free play time. If you want unlimited access, you can purchase the full version as an in-app purchase.

Based on the filter of the iconic Soviet synthesizer from the 1980s, PolyIvoks Filter brings the vintage analog sound to your iPhone in stereo mode. The precise port of the Rack Extensions plug-in ensures an authentic and high-quality experience.

With PolyIvoks Filter, you can expect a range of features including undo/redo functionality, A/B comparison, and 2x/4x/8x upsampling. The GUI is also scalable, allowing you to customize the interface to your preference.

The modulator section houses the LFO controls, offering four waveforms including noise and a stepped function for sample and hold effects. The filter section provides controls for cutoff, resonance, LPF to BPF switch, modulation (LFO) level, and envelope level. Additionally, there is a repeating attack/decay envelope in the envelope section. The master unit includes controls for envelope level, volume, and a digital/analog switch.

To use PolyIvoks Filter, you will need an AUv3-compatible host app such as GarageBand, Auria, AUM, Cubasis, and more. Once installed, PolyIvoks Filter will appear in the list of audio unit extensions for effect plug-ins in the host app.
