Delaylay is a wonderful weird free and open source delay VST Plugin.
It features a lot of different delay modes – from Karplus-Strong like synthesis to DAW tempo synced delay lines – on one controller.
Delaylay works in four different modes from simple stereo to spread, detuned, down-pitched and half-timed stereo delay with ping pong effect applied.
Delaylay interpolates smoothly between different delay times, depending on the last delay time set.
