It's a MIDI-only FX version for hosts requiring pure MIDI processing.



This audio effect plugin offers vintage-inspired stereo delay with deep modulation, flexible filtering, and creative timing options. It allows for precise control over echoes, from warm analog sounds to shimmering textures, and integrates an advanced modulation system for unique sound design.


This app offers a vintage-inspired stereo delay effect with advanced modulation, flexible filtering, and precise timing controls. It allows users to sculpt unique echo textures, from warm analog sounds to complex, evolving soundscapes.


This audio effect plugin offers independent control over harmonics and frequencies. It allows detailed sculpting of pitch and frequency shifts across the entire spectrum, enabling unique vocal textures and experimental sound design.


Transform audio into lush pads, frozen textures, or spectral motion with this multi-curve spectral blur and freeze effect. Shape different parts of the spectrum with independent blur times, and explore evolving drones and unique spectral transitions.


This audio effect plugin offers analog-modeled filters with flexible routing and dynamic modulation for creative sound design. It provides extensive control over tone shaping and complex filtering with various filter types and configurations.


This live granular processor allows you to break down audio into small pieces or create atmospheric soundscapes. It features dual live buffers, a musical grain engine with tempo sync, and expressive pitch control with MIDI support. Shape your sound with an intuitive XY pad and mix section for detailed sonic manipulation.


Explore four distinct distortion effects—Saturation, BitCrush, Ring Modulation, and Downsampling—blended and controlled via an intuitive XY pad. Shape harmonics, reduce digital resolution, introduce inharmonic motion, and create classic digital degradation for unique audio textures.


This advanced audio effect plugin offers precise spectral fusion and multi-curve vocoding. It allows users to extract spectral characteristics from one audio source and apply them to another, enabling detailed transformations from subtle shading to extreme effects.


This audio effect plugin allows for intricate, non-linear filter shaping and dynamic spectral transformations. Create unique soundscapes by designing custom filter curves and modulating them for subtle to extreme audio manipulation.


This app offers a unique spectral delay effect with advanced control over thousands of parallel delays using a single curve. It allows for real-time modulation, tempo-syncing, and precise feedback management for expansive sonic exploration.
