GSDSP Quantum Delay is a powerful audio effect plugin that offers a wide range of features for manipulating time and creating unique delay effects. It includes two distinct modes - Tape mode for a retro feel and Fade mode for a clean sound. Users can easily switch between BPM synchronization, 5-tuplets, or specify delay times in milliseconds. The Fine control allows for precise adjustments, while modulation capabilities provide unprecedented control over delay lines.

Nested filters within the feedback path enable users to sculpt echoes with lowpass, highpass, and bandpass filters. Adding modulation adds dynamic movement and depth to the echoes. The feedback intensity can be defined in traditional percentage or dB/s, with options for crossfeed and over-feedback modes for creating classic or intense delay effects.

GSDSP Quantum Delay supports stereo and dual mono modes for enhanced stereo effects and control. Users can introduce randomness with parameter randomization and utilize a comprehensive modulation system featuring LFOs, Random Generators, Envelope Followers, Macros, and dynamic chaotic systems. Compatible with Logic Pro, AUM, Cubasis, GarageBand, as an AUv3 plugin, and also available as a desktop version for Windows and macOS (VST3 / AU / AAX).
