A dual-delay that behaves like a full delay rack
QDelay is a free dual-delay built for modern mixing and creative FX. It can stay clean for everyday work (vocals, synths, guitars), or get weird—in a good way—thanks to ducking, groove controls, tape-style character, diffusion, reverse, and pitch-in-feedback.
Quick description
- Clean vocal throws: ducking keeps repeats out of the way while the vocal is present, then brings them back in the gaps.
- Groovy rhythmic delays: Tap mode + Swing/Feel makes echoes bounce instead of marching.
- Wide club echoes: Ping-pong + feedback width for big stereo movement.
- Transitions & sound design: Reverse + pitch in feedback for rising/falling tails.
