QuatroMod combines four powerful modulation effects into a single plugin, offering a comprehensive solution for enhancing stereo audio tracks. It integrates a through-zero flanger, a rich multi-delay chorus, a diffusion-based chorus effect, and a frequency shifter, each delivering distinctive modulation characteristics. This collection allows producers to explore a wide range of textures and movement, from subtle widening to bold, experimental sound shaping.

The flanger mode features precise control over offset and feedback to create expansive stereo effects, while the chorus mode employs multiple delay lines modulated at different rates for a lush and thick sound. The diffusion chorus adds a unique character by repurposing reverb diffusion techniques, making it particularly effective for creative sound design. The frequency shifter offers smooth pitch shifting that can subtly enhance pads or dramatically transform audio sources, making it an essential tool for modern production workflows.

QuatroMod's user interface is vector-based and resizable, providing crisp visuals on Retina and 4K displays. It supports a variety of plugin formats across Windows and macOS, ensuring seamless integration in diverse digital audio workstations. This makes the plugin accessible for producers seeking high-quality modulation effects with flexible control and broad compatibility.
